Published: September 2023

Magnolia citrata Noot. & Chalermglin was collected in the Central Highlands of Vietnam and examined for its essential oils’ chemical compositions and antimicrobial activities. The essential oils were obtained from the leaves, twigs, and stem barks of M. citrata using hydrodistillation, then analyzed using Gas Chromatography-Mass Spectrometry (GC-MS) and evaluated for antimicrobial activities. The yields of essential oils were 0.06, 0.51, and 0.16% from twigs, leaves, and stem barks, respectively. A total of forty-three compounds were identified in essential oils, accounting for 98.0, 98.8, and 98.4%, respectively. The major constituents of the oils from leaves and twigs varied slightly. Accordingly, geranial (23.1%), neral (22.5%), linalool (22.5%), and sylvestrene (6.3%) were found in the leaves, while geranial (30.9%), neral (29.6%), sylvestrene (11.8%), and linalool (6.1%) were found in the twigs. In addition, sylvestrene was the major component comprising 51.8% of the stem bark oils. Other compounds present in high quantities in this oil included safrole (11.6%), geranial (6.9%), sabinene (6.9%), and neral (6.6%). The antimicrobial activities of the essential oil samples were tested against six bacterial strains and one yeast strain for the first time. The results indicated that essential oils from M. citrata had strong antimicrobial activities. At the concentration of 64 µg/mL, the essential oils from its three parts effectively inhibited the growth of the Gram-positive bacteria Enterococcus faecalis, Staphylococcus aureus, and Bacillus cereus, as well as the yeast Candida albicans. Against the Gram-negative bacteria, including Escherichia coli, Pseudomonas aeruginsa, and Salmonella enterica, the effective concentrations of the oils for inhibition varied from 128 µg/mL to 256 µg/mL.

According to The Simple View of Reading, both decoding and linguistic comprehension processes are needed for reading comprehension for L1 as well as L2 students. Previous research has shown that early support is important for students who struggle with reading. The thesis aims to investigate the role of decoding and comprehension for students learning to read in Swedish as L2 and how teaching and early special support can promote reading development. The first study in the thesis has a cross-sectional design and examines scores on decoding, vocabulary, and reading comprehension. The results showed that L2 students in grades 1-3 in Sweden had significantly weaker scores on all three tests than L1 students and that both decoding and vocabulary are related to reading comprehension. The results also showed that a significantly higher proprtion of L2 students were in need of extra support in reading. The second study is a systematic scoping review that identifies findings from reading intervention studies of L2 students. The results showed that additional small group or within-class programs can support L2 students when teaching is matched to their individual needs. The study also supported the view that instruction in skills in one language can transfer to skills in another. The third study has a between-groups design and investigates the impact of a Response to Intervention (RTI) model with a focus on decoding. The results showed that the RTI model had the potential to promote both L1 and L2 student's reading ability but to a lesser extent among L2 students. The forth study has a single subject design and examines the impact of a systematic word decoding intervention in Swedish for students learning Swedish as L2. All students improved their word decoding ability. In conclusion, it can be seen that differentiated balanced reading instruction and early support in an inclusive setting can promote reading ability in students learning Swedish as a second language. A second language perspective in early reading education is discussed.

Resilience: A Cognitive and Psychosocial Phenomenon
Authors: Nemeth Darlyne , Capps Cody , Palamar Olesia
Published: September 2023

Resilient individuals may be identified as those who are firmly grounded in today, who have benefited from yesterday, and who have the capacity of seeing themselves in tomorrow. Therefore, it is important to understand the underlying dynamics that allow these people to be resilient. The nature-nurture concept contributes to an individual’s resilience. Via neuroscience research it is becoming abundantly clear that nature is the stronger factor. The contribution of nurture, however, must also be considered. What does nurture contribute to the individual and/or the environment? Does proper caretaking of the individual and the environment increase resilience, or does resilience merely depend upon the neuroscience of genetics? This article will explore the multifaceted concept of resilience.

Cognitive A Priori and Amodal Perception in the Focus of Experimental Philosophy
Authors: Zaitseva Natalia
Published: September 2023

The article discusses the prospects of neurophenomenology as a substantiative theory with respect to the results of neurocognitive research. Some relevant ideas and theoretical findings of the phenomenology of Edmund Husserl, which are of great importance for the interpretation of experimental data from neuroscience, are consistently presented and analyzed. In particular, the emphasis is made on the procedure of analogizing apperception (appresentation), based on an even deeper pairing mechanism. In so doing, I consider and trace the evolution of these ideas in Husserl's works of different years and periods. As an example, that clearly demonstrates the universal a priori rock-bottom role of appresentation in cognition and perception, the procedure of amodal completion is chosen. Amodal completion is the process of perception by which an object is apprehended as a whole while some parts of it are occluded by other objects. These research seems to open up wide opportunities for neurophenomenology as the theoretical basis of the sciences of consciousness, mind and brain.

Neuroticism, Preoccupied Attachment Style, and a Chronic Disease Condition as Predictors of Reminiscence During an Illness
Authors: Ecer Emrullah
Published: September 2023

The main aim of the study was to analyse to what extent attachment styles, personality traits, and a chronic disease condition were predictors of reminiscence during an illness. The second goal was to examine the relationship between personality traits, attachment styles, and reminiscence during an illness. Reminiscence during an illness was divided into two categories as emotional and cognitive patterns of the past experiences. In the study, there were 73 Turkish participants (43 males, 58.9%). The mean age of participants was 40.2 (SD = 11.8). Results indicated that preoccupied attachment style, agreeableness, and whether having a chronic disease explain with 22.4 percent of the total variance of reminiscence during an illness. Reminiscence during an illness was positively related to preoccupied attachment style and negatively correlated with agreeableness along with extroversion. Gender had a significant effect on openness to experience, preoccupied attachment style, neuroticism, and negative cognitive reminiscence during an illness. Finally, chronic illness had a significant impact on reminiscence during an illness and neuroticism. The study suggested that personality traits, attachment styles, and gender affected the reminiscence during an illness.

Authors: Tokareva Yulia A. , Volik Svetlana V.
Published: September 2023

At the present stage of the development of the system of psychological and pedagogical support for the subjects of the educational process, the goal of timely diagnosis and identification children with developmental problems that are the reason for the lack of the necessary psychological basis to master the educational program becomes the most urgent. According to research over the past 10 years, the number of primary school pupils who fail to cope with the program with preserved intelligence is steadily growing. The study aimed at identifying the psychological characteristics of children with developmental disabilities having learning problems involved 230 pupils of junior high school in the Sverdlovsk region, 111 of them girls (48 %) and 119 boys (52 %). The main diagnostic method was the Toulouse-Pieron test, universal for psychophysiological assessment. The most expressed signs of the minimal brain dysfunction are deficiencies in the formation of memory, thinking, voluntary attention, increased mental fatigue, distractibility, motor uncontrollability, weakness of self-regulation. As a result of the study hypotheses were confirmed that in children with the minimal brain dysfunctions, depending on the severity of the type, there are features of the development of the higher mental functions and the nature of behavior in the learning process that require special techniques for monitoring and evaluating pupils’ knowledge.
Sources of Population Records of Early Yekaterinburg: Peculiarities and Information Potential
Authors: Borodina Elena , Tsemenkova Svetlana
Published: September 2023

This article studies the demographic history of Yekaterinburg in the second quarter of the eighteenth century. The authors focus on the population changes in the city between 1723 and 1744. This issue remains relevant since currently, there are no books or articles that would provide consistent data on the number of residents who settled near the Yekaterinburg plant. The analysis of historiography demonstrates that a significant part of scholars provide information about the composition and population of the city only for some years of its existence, without explaining the features of the primary sources underlying their research. This, in turn, has led to the fact that historians are split when it comes to estimates of the population of the fortress factory in the first years of its existence. In connection with the celebration of the city’s tercentenary, the researchers’ appeal to the history of the population of Yekaterinburg in the second quarter of the eighteenth century becomes even more significant. The work aims to analyse the features and information capabilities of primary sources containing data on the population of the fortress and plant. The main research methods include methods of primary source studies. In addition, the authors use the comparative method and method of system analysis, as well as the method of diachronic analysis. Employing these methods, the authors establish the approximate number and reconstruct the composition and main groups of residents of the future city. Also, they demonstrate that along with national censuses, the mining administration exercised police control over the structure and population numbers to solve various tasks. Among them are the organization of production processes, the defence of factories during the Bashkir uprising of 1735–1740, control over the population on the territory of the city, etc. One of the results of the study is the clarification of the male population of Yekaterinburg. Comparison of data from different years helps draw conclusions about the positive dynamics of the number of inhabitants in the first decades of the city’s existence. The increase in the figures and change in the composition of the population affected the appearance of the settlement. It acquired urban features. Thus, in the second quarter of the eighteenth century, there were all the prerequisites for Yekaterinburg to acquire the status of a city.
W. de Henning’s Position on the Privatisation of State-Owned Metallurgy
Authors: Akishin Mikhail
Published: September 2023

The formation of metallurgy in Russia occurred during the Northern War, which predetermined the dominance of state ownership in this sector of the economy. During the end of the war, Peter I embarked on a policy of privatising the state-owned industry. The regulatory and legal basis for privatisation was the Berg Privileges of 1719. However, having begun the policy of transferring state-owned factories to companies of private industrialists, Peter I was not consistent. He thought about the development of the state-owned metallurgy of the Urals and, at the same time, considered the possibility of its transfer to private industrialists in the future. This article examines the position of W. de Henning on the issue of privatisation. During his leadership of the local mining industry in 1720–1722, V. N. Tatishchev was the first to raise the question of the need to privatise the state-owned metallurgy of the Urals. In 1722, Peter I appointed Henning as head of the state mining industry of the Urals, giving him extensive administrative power. In 1722–1724, Henning managed to reconstruct the old state-owned factories and build new ones – Yekaterinburg, Polevskoy, Pyskor, and Yagoshikha. Meanwhile, in 1724, Tatishchev presented to Peter I projects for the privatisation of state-owned factories in the Urals. The emperor “accepted these projects as beneficial ones” but at the same time, developed a complex procedure for considering privatisation issues in the relevant central and local state bodies. In 1724, Tatishchev’s projects received negative reviews from the Berg Collegium and Henning, who pointed to high profits from state-owned factories. At the same time, Henning proposed his projects which either meant the transfer of state-owned factories to the company of Peter I, A. D. Menshikov, F. M. Apraksin, etc., or the transfer of Pyskor plants to him, A. Stroganov, and M. Turchaninov. However, Tatishchev and Henning’s discussion of the projects ground to a halt due to the death of Peter I. Again, the question of privatisation of the state-owned metallurgy of the Urals arose during the so-called “sales crisis” of 1729–1732 and was already post-suppressed by Henning. Henning’s privatisation projects were discussed in the Senate, the Berg Board, and the Monetary Commission. In 1733, a Commission on state-owned factories was established. However, in 1732, the “sales crisis” was overcome, and Henning abandoned his privatisation projects. He finally came to the conclusion that state ownership in metallurgy was no less effective than private ownership and began a new stage of construction of state-owned factories in the Urals. The same position was held by Tatishchev, who replaced Henning in 1734–1737 as head of the Ural plants. The subsequent history of privatisation campaigns of the second half of the eighteenth – early twentieth centuries confirmed the validity of this conclusion, with considerable state ownership in metallurgy not only remaining but also expanding.
The Construction of the First Volga-Don Canal of Peter the Great
Authors: Kiyashko Yakov , Kleitman Alexander
Published: September 2023

This article studies the history behind the construction of a navigable canal meant to connect the Volga and the Don through their tributaries, the Kamyshinka and the Ilovlya, in 1697–1698. The authors aim to clarify the history of the first project of Peter the Great to modernise the country’s transport infrastructure and analyse it in the context of the events of the initial stage of the Petrine era. The study refers to maps and plans of the area, materials of office work – documents that both have been previously published and are introduced into scholarly circulation for the first time and come from the funds of the Russian State Archive of Ancient Acts, as well as the results of archaeological exploration carried out at the Selimov Val cultural heritage site in the village of Petrov Val in Kamyshin district of Volgograd Region. The study demonstrates that the period of 1697–1698 saw the construction of a structure meant to perform both fortification and hydraulic functions in the interfluve of the Kamyshinka and the Ilovlya. B. A. Golitsyn and E. I. Ukraintsоv controlled the construction, while Prince A. F. Shakhovsky directly supervised it. The project was authored by engineer J. Bröckell, and Peter I attached great importance to it, repeatedly discussing it with European statesmen and scientists during the Great Embassy. Pososhniye lyudi (people in sokha-based military service) were recruited in the settlements and districts of the Volga cities and did the construction work on the Kamyshinka. Logging was carried out along the River Sura in Alatorsky and Yadrinsky uyezds. By the end of 1697, a fortification was built where the Kamyshinka and the Ilovlya were closest to each other, the remains of the fortification perfectly preserved to this day. However, it turned out impossible to build a navigable canal. Having received news of the departure of J. Bröckell, the author of the first project, from the country in the winter of 1698, Peter I and other members of the Great Embassy began to look for and invite “sluice masters”, i. e. specialists in the construction of navigable canals. Thus, the first unsuccessful attempt to connect the Volga and the Don was why the tsar paid close attention to the theoretical and practical issues of building navigable canals as a significant area of science and technology.
Adam Laxman’s Expedition in the Colonial Conflict in the North Pacific
Authors: Petrov Alexander
Published: September 2023

This article examines the history of the emergence of official Russian-Japanese relations in the late eighteenth century. The work focuses on unique archival materials from the SARC, RSA of the Navy, MD RSL, RSAAA, etc. The article refers to collections of documents, works by V. N. Berkha and E. A. Bolkhovitinov, and modern authors. The author analyses the first contacts between Russia and Japan, which became the prerequisites for the 1792–1793 expedition of Adam Laxman to Japan. Also, he studies the role of Dembei, San’emon, Sōza, and Gonza, the first Japanese nationals who visited Russia, in the development of Russian-Japanese relations and the study of Japanese culture and the Japanese language in Russia. In light of the struggle for colonies in the North Pacific in the late eighteenth century, the article also considers a peaceful but quick way of establishing relations, characteristic of Russia at that time, opposed to Japan’s desire to ritualise and slow down this process. The optimism, widely spread in the late eighteenth century in the establishment of trade and diplomatic relations, was fuelled, on the one hand, by numerous petitions from merchants with a request to establish trade with Japan and, on the other hand, by the desire of the state to win the struggle for spheres of influence in the North Pacific, in which Great Britain actively participated in the 1790s. Despite the success of Adam Laxman’s expedition, this approach to establishing international relations between countries was not to be preserved, and by the middle of the nineteenth century, it was replaced by a military-coercive one.

Arguably the most popular remote-sensing products are classified images. However, there are no definitive procedures to assess classification accuracy that simultaneously consider resources available and field efforts. The explosive usage of unmanned aerial systems (UAS) in land surveys adds new challenges to classification assessment, as orthorectified images usually contain significant artifacts. This study aims to identify the optimal ratio between training and validation sample size within a supervised classification approach applied to UAS orthophotos. As a case study, we used a wetland area west of Portland, OR, USA, treated with various glyphosate formulations to control Phalaris arundinacea, commonly known as reed canary grass. A completely randomized design with five replications and six glyphosate formulations was used to assess P. arundinacea vigor following repeated herbicide applications. The change in P. arundinacea vitality was monitored with high-resolution four-band imagery acquired with a SlantRange 3PX camera installed on a DJI Matrice 210. The orthophotos created from images were produced with Pix4D, which was subsequently preprocessed with ERDAS Imagine 2020 to reduce the noise, shadows, and artifacts. All images were classified with the maximum likelihood classification algorithm. Simple random and stratified random sampling methods were applied to collect training and validation samples, evaluating eight ratios of training to validation samples to assess their classification accuracy. We found that increasing the training-to-validation sample size ratio enhances accuracy, with the 3:1 ratio being the most reliable in classifying P. arundinacea vigor. Our study provides evidence that image preprocessing and enhancement are essential for UAS-based imagery.

Phenolic compounds are very effective for the cure of various neurological and pathological diseases. Current study was conducted to estimate the Phenolic compounds through HPLC and to perform the anti-Alzheimer activity from two aquatic Leptosporangiate ferns; Marsilea quadrifolia L. and Salvinia molesta D. Crushed leaves were subjected to Microwave Assisted Extraction to prepare plant leave ethanolic extract of plants under study. Aluminum chloride induced Alzheimer’s disease model in rats by estimating behavioural and biochemical parameters were measured for ethanolic extract of both plants. Different behavioural tests were performed for neuromuscular coordination estimation and hole board test for exploratory behaviour were performed. The levels of AChE inhibitory activity and antioxidant enzymes were estimated on brain homogenates and Histopathological analysis were also performed. Phenolic compounds of leaf extracts were noted for HPLC chromatograms of standard compounds with Gallic acid (33.76 ± 0.08) higher in M. quadrifolia L. and Salicylic acid (12.45 ± 0.07) higher in S. molesta D. S Mitchel. Histopathological analysis showed that M. quadrifolia and S. molesta reversed the neurofibrillary tangles, degenerative changes, neuronal loss and neuroinflammation in the brain architecture. Both ferns at a dose of 500 mg/kg and 1000mg/kg significantly improved the Aluminium chloride induced neurotoxicity by modulating cognitive disabilities and motor dysfunctions, and normalized the biochemical alteration of acetylcholinesterase and antioxidant enzymes. In conclusion, both plants M. quadrifolia and S. molesta improved behavioural and biochemical parameters and therefore will be effective in treatment of neurodegenerative disorders via countless underlying mechanistic pathways.
Physicochemical, bioactive compounds and antioxidant activities of sweet red corn under different drying methods
Authors: PHUSEERIT Onanong , CHUMROENPHAT Theeraphan
Published: September 2023

This study investigated the physicochemical properties, bioactive compounds, and antioxidant activities of sweet red corn under different drying methods. The color characteristics of the corn varied significantly based on the drying method employed. Freeze-drying resulted in the lightest color, while sun drying and hot air drying at different temperatures showed intermediate and varying color parameters. The total phenolic and flavonoid content decreased after drying, with heat drying methods exhibiting a greater decrease compared to freeze-drying. Microstructural analysis revealed changes in cell structure and starch granules, with freeze-dried samples displaying distinct characteristics. The sugar content decreased in all drying methods compared to the fresh sample. The amino acid content also decreased after drying, with heat drying methods affecting certain amino acids more than others. Different phenolic acids and flavonoids were detected, with their concentrations varying depending on the drying method. Fresh corn exhibited the highest antioxidant activity, while freeze-drying retained a significant amount. Sun drying and high-temperature drying methods resulted in decreased antioxidant activity. These findings underscore the importance of selecting appropriate drying techniques to preserve desired attributes and beneficial properties of corn.
Structure–property relationship in edible pectin–alginate/orange peel biocomposite films
Authors: Mocan Merve , Uncu Sinan Barış
Published: September 2023

Biodegradable plastics can help tackle plastic packaging waste, which has serious consequences on the environment. However, current bio-based materials often lack strength, have poor thermal and barrier properties and are expensive. This study proposes a solution: biodegradable, edible pectin–alginate films reinforced with abundant and inexpensive orange peel powder (OPP). This study stands out for its comprehensive analysis of mechanical, thermal, barrier, morphological and biodegradable properties by adjusting the type, amount and size of OPP in the formulation. The resulting fully biodegradable films with 2% calcium chloride (CaCl2), 0.7 g/g glycerol and 30% finely ground OPP not only matched the quality of commercial packaging films in terms of mechanical properties but also exhibited promising qualities in terms of thermal, morphological and water barrier properties for packaging applications. Made from natural, edible and vegan materials, these films offer an eco-friendly alternative to non-biodegradable plastics, enhancing biocomposite properties and also providing a sustainable solution to organic waste.

Introducción: Las expectativas académicas representan aquello que los estudiantes esperan alcanzar durante su formación y son un factor predictivo del desempeño académico y social. Estas expectativas académicas son moldeadas por los padres, luego la educación de estos es una variable importante en el desarrollo académico de los hijos. Si bien los progenitores proyectan sus aspiraciones sobre sus hijos, los motivan a tener altos niveles de aspiración y son los responsables de crear ambientes intelectualmente más estimulantes, el objetivo de este estudio fue identificar las diferencias en las expectativas académicas de una muestra de estudiantes, según el nivel de escolaridad de sus padres.
Método: esta investigación contó con la participación de 261 estudiantes colombianos universitarios quienes estén cursando su primer año de pregrado, entre los 16 y 54 años (media=21.9). Para este estudio se utilizó el Cuestionario de Percepciones Académicas-Expectativas (CPA-E), se obtuvo los puntajes de cada participante, junto con sus datos sociodemográficos que estipulaban el nivel de escolaridad de los padres, y se corrieron los datos descriptivos y los análisis de varianza unidireccional (ANOVA).
Resultados: las expectativas académicas de los estudiantes con ambos padres sin educación superior, se encuentran por debajo de la media, siendo significativamente diferentes a los puntajes de expectativas académicas de individuos con uno o ambos padres con estudios superiores.
Discusión: se demuestra la relevancia y necesidad del acceso a la educación para la mayoría de la población colombiana, entendiendo que este es un factor influyente en las expectativas académicas de una persona, y que debe tenerse un acompañamiento diferencial a los estudiantes con padres sin formación profesional.

Today, information security reigns in absolutely all areas of human activity. Security breaches always have consequences, but depending on the structure, they can be invisible, or vice versa, stop the activities of an organization or even a country. The issue of ensuring information security of critical information infrastructure facilities has become the most discussed today. The state and its regulators to develop many regulatory legal documents that contain requirements for the system of protection of critical information infrastructure facilities of various levels of significance. However, no one has ever created a single technique that would show the real state of information security of a critical information infrastructure object. As a result, both the organization and regulators see only a general picture of the state of the defense system, which in turn creates many vulnerabilities that an attacker can use to carry out an attack. As a result of the attack on the object of critical information infrastructure, harm can be done not only to organizations, but also to people, the work processes of the entire state can be violated. That is why the issue of creating such a methodology becomes not only relevant, but also necessary both for the internal control of the organization itself and for automating the work of regulators during the next inspections. The methodology will show not only a high-quality assessment of the state of the protection system, but also show the possible vulnerabilities of the organization that need to be closed to improve the effectiveness of all protection.

Os resultados indicam que a maioria desconhecia a divulgação científica até cursar a universidade e que a participação nas atividades colabora com a compreensão dessa prática. Foram identificadas cinco aprendizagens principais: capacidade de comunicação, mediação de atividades pedagógicas, pensamento crítico, planejamento e fundamentos teórico-práticos da ação docente. Tais categorias se relacionam diretamente a conhecimentos necessários à prática docente, em especial às dimensões propostas por Shulman de: conhecimento pedagógico geral; conhecimento dos aprendizes e suas características; conhecimento dos contextos educacionais; conhecimento dos fins, propósitos e valores da educação. Em menor grau apareceram indicações ao conhecimento de conteúdo, onde a participação em ações de divulgação científica pode contribuir para formar professores que analisam seu planejamento, suas estratégias comunicativas e os impactos para a aprendizagem.
Um olhar sobre as definições de abordagem temática na perspectiva de Paulo Freire: o que dizem os autores?
Authors: Morschheiser Luana Marciele , Della Justina Lourdes Aparecida , Franzen Leite Rosana
Published: September 2023

O presente trabalho surge da dificuldade em identificar e elencar definições padronizadas para as terminologias empregadas ao uso da palavra “Tema”, em especial a utilização da Abordagem Temática. Diante disso, apresentamos o emprego do termo Abordagem Temática como metodologia de ensino conforme descrita pelos autores pertinentes à área de ensino, aos quais destacamos Paulo Freire, famoso filósofo e educador brasileiro, precursor da metodologia de ensino em estudo. Apresentamos assim, um artigo de reflexão cujo objetivo é justamente explorar os caminhos percorridos pela metodologia da Abordagem Temática, elencando algumas de suas definições relacionadas à pesquisa em ensino de ciências, ao qual destacamos: Tema Gerador, Investigação Temática, Abordagem Temática Freireana e por fim uma breve articulação com o currículo, por meio da Práxis Curricular via Tema Gerador. Atrelada a proposta de educação de Freire, uma metodologia que priorize a ruptura do ensino propedêutico só tem a contribuir com as concepções de ensino e aprendizagem, com isso o uso dos temas em sala de aula permite uma ampla variação de atividades, sendo possível identificar a importância da associação entre os conceitos científicos com o meio social e cultural em que determinada comunidade escolar se encontra inserida.
Revisión documental sobre la formación y el conocimiento del profesor de matemáticas
Authors: Cruz-Rojas Gilbert Andrés
Published: September 2023

Este artículo presenta los resultados de una revisión documental de artículos de investigación publicados en el periodo 2015-2019 en el Congress of the European Society for Research in Mathematics Education (CERME), Psychology mathematics education (PME) y North American Chapter of the International Group for the Psychology of Mathematics Education (PME-NA). Esta revisión se realizó con la intención de determinar los problemas de investigaciones, enfoques teóricos y metodológicos que se utilizan en el estudio sobre el conocimiento del profesor de matemáticas que se ocupan de habilidades situadas, y los enfoques que permiten estudiar prácticas con tecnología. Se toma como perspectiva metodológica la investigación documental, la cual, se desarrolla mediante una clasificación de documentos, a través de palabras claves como la Formación Docente, Conocimiento del Profesor de Matemáticas, Competencia Matemática y el Enfoque Documental. Se reconoce a partir del desarrollo metodológico, que existe una discusión al interior de la comunidad de educadores matemáticos, frente a los procesos de formación docente y su incidencia en las prácticas de enseñanza; en especial al sentido, alcances y limitaciones de programas de formación de profesores de matemáticas.

Published: September 2023

En España se han diseñado e implementado diversos programas de intervención para la mejora de las competencias emocionales y el desarrollo del Conocimiento Didáctico del Contenido (CDC) de los maestros en formación inicial, los cuales mediante la indagación se comprometen en aspectos emocionales e intelectuales en el aprendizaje científico. En este artículo se analiza el cambio en las emociones hacia la metodología indagatoria en una asignatura de Didáctica de las Ciencias con intervención emocional, en el cual participaron 54 estudiantes matriculados en el Grado de Maestro en Educación Primaria de la Universidad de Huelva, España, quienes manifestaron en un cuestionario con escala tipo Likert su grado de acuerdo en la intensidad de siete emociones negativas y siete emociones positivas, antes, durante y después de la intervención; también, a través de observaciones de aula, narrativas, entrevistas a la formadora y a una profesora novel, se establecen las posibles causas del cambio. El tratamiento de los datos se basó en análisis descriptivo, análisis factorial exploratorio y pruebas no paramétricas, donde los resultados confirmaron el predominio de las emociones positivas en los tres momentos, pues se registra un incremento significativo en entusiasmo, satisfacción, interés, aceptación, tranquilidad, bienestar y asombro; también se identifica una disminución significativa en susto, temor y aburrimiento, donde el abordaje de una cuestión sociocientífica vinculada al contexto andaluz, la aplicación de estrategias de regulación y la salida al medio natural, potencian el cambio en las emociones.
¿Qué nos cuenta Pachamama? Una experiencia de diálogo de saberes, vivires y formación docente descolonizadora en educación ambiental

Con la intencionalidad de aportar a una formación docente descolonizadora en Educación en Ciencias Naturales, Ambiental y en Salud, presentamos la reconstrucción narrativa de un proceso de formación docente en educación ambiental. Enfocado desde el Pensamiento Ambiental Latinoamericano, fue implementado desde el diálogo de saberes entre grupos académicos y organizaciones socioterritoriales que defienden humedales en disputa con el extractivismo inmobiliario. Desde una metodología de sistematización de experiencias educativas, analizamos escenas que nos permiten caracterizar elementos descolonizadores del proceso de pedagogización de un conflicto ambiental llevado adelante.
El razonamiento covariacional y su papel en el estudio de la integral definida desde la resolución de problemas
Authors: Martínez-Miraval Mihály André , García-Rodríguez Martha Leticia
Published: September 2023

El objetivo del presente estudio fue analizar si existen descriptores asociados con un razonamiento covariacional en los procesos de resolución de problemas sobre la integral definida. En las investigaciones sobre este tema se identifica de forma implícita o explícita la presencia del razonamiento covariacional, lo que sugiere la necesidad de conocer sobre la relación entre este tipo de razonamiento y los procesos de resolución que involucran el concepto de integral definida. En este estudio se adoptó el constructo teórico de razonamiento covariacional y se llevó a cabo una investigación documental mediante una revisión sistemática de trabajos de investigación que abordaron el estudio de la integral definida y que fueron publicados durante los últimos ocho años, de acuerdo con cuatro índices de valoración en el área de Educación Matemática. Como resultado de la revisión sistemática, se identificaron cuatro trabajos que abordan este concepto mediante procesos de aproximación o acumulación; en ellos se reporta que los estudiantes hicieron referencia a: cambios en el valor de una cantidad como si ocurrieran simultáneamente con los cambios en el valor de otra; dos variables cambiando continuamente; y, un elemento que resulta de la coordinación de los valores de dos cantidades que varían juntas, todos descriptores de diferentes niveles de razonamiento covariacional. Se concluye que los estudiantes razonan covariacionalmente durante la resolución de problemas sobre la integral definida y parece que las características de su razonamiento están relacionadas con el éxito en el proceso de resolución, aspecto que requiere de mayor investigación.
Enseñanza de la biología y cuidado de la vida. Aporte para una Colombia en paz
Authors: Bravo-Osorio Leidy Marcela , Pacheco-Calderón Diana
Published: September 2023

Se presentan resultados de la investigación: “Enseñanza de la biología y cuidado de la vida”, la cual incluye reflexiones respecto al cuidado de la vida desde la comprensión de las relaciones entre naturaleza y cultura, las ontologías relacionales y el pluralismo epistémico. Parte de la sistematización de seis trabajos de grado para optar al título de licenciados en Biología, los cuales se desarrollan desde una mirada de la enseñanza de la biología en contexto con enfoque intercultural, teniendo como apuesta política para la formación de maestros, una reflexión que implica comprender la enseñanza de la biología como práctica cultural y que la paz no es solo entre humanos, sino también con los otros seres y existencias con los que compartimos la vida. Dentro de los resultados se encuentra la pertinencia de vincular las concepciones sobre la vida para la enseñanza de la biología, como aporte para la renovación de memoria biocultural y por esa vía, el fortalecimiento de la identidad y del territorio, expresado en el empoderamiento de las comunidades que conduzcan a posicionar el derecho a una vida digna, donde la paz es plural, desde cada una de las formas en que es posible vivirla.
