Authors: İLERİ Onur , AVCI Süleyman , KOÇ Ali
Published: December 2021

In this study, some common forage pea cultivars (Golyazi, Ozkaynak, Taskent, Tore, and Urunlu) and a population of Ardahan were investigated during 2015 and 2016 years in Eskisehir condition to determine the forage yield and quality parameters. The fresh forage yield of autumn-sown forage pea (24,36 t/ha) was higher than the spring-sown plants (13,42 t/ha). Golyazi and Urunlu cultivars had lower fresh forage yields (14,63 and 14,81 t/ha respectively) than the other genotypes and Ozkaynak, Taskent, Tore (cvs.), and Ardahan (pop.) were statistically ranked in the same group (between 22,52 and 19,92 t/ha). The dry matter yield of forage pea genotypes did not differ significantly between the autumn and spring seasons. The highest dry matter ratio was 25,06% in Taskent while the lowest was 22,06% in Ozkaynak. The crude protein was higher at autumn sowing (21,17%) than the spring sowing (18,36%) and Ozkaynak had the highest value (21,53%) while Ardahan population was the lowest (17,76%). NDF content was higher in the spring season (37,62%) but only the difference between Taskent (37,60%) and Golyazi (34,06%) was significant among the genotypes. Variation in the ADF content was only significant among the genotypes and the difference between Taskent (33,41%) and Golyazi (31,62%) was significant only as similar to NDF. In sum, Ozkaynak, Taskent, Tore cultivars produce more yield with a satisfying quality by sowing in autumn at Eskişehir conditions, and the population of Ardahan has a high potential to develop new cultivars suitable for the region.
THEORETICAL BASIS AND SCIENTIFIC VIEWS ON SELFMANAGEMENT IN THE ORGANIZATION
Authors: Mietule Iveta , Chenchak Oksana
Published: December 2021

The changes that have taken place in the economy, politics, technology and innovation increase the requirements for management personnel, their professionalism, training and retraining. Organizations cannot take on the development of all the skills of all managers, so maintaining their constant growth and development becomes a necessity for managers and, in general, for any other person who wants to use their time efficiently and make it work. This should become a kind of habit, which is achieved by long work on yourself, the development of perseverance, as well as the ability to think rationally. Nowadays, selfmanagement and self-development of personnel are becoming a factor in the survival of the economy in market conditions, strengthening the position of management in various countries. The aim of the paper is to analyse various research studies in regard to selfmanagement and to give recommendations to improve it. The paper discusses the effective concepts and approaches of various scientists, shows the importance of self-government in work and daily life to achieve the desired success and helps to assess the effectiveness of selfgovernment at the global level. The research used the theoretical information of foreign scientists and Internet resources. The scientific research methods that were used in the research are as follows: literature analysis and synthesis, the monographic method, and content analysis.
COMPARISON OF VEHICLE REGISTRATION SERVICES IN THE BALTIC STATES
Authors: Romaņuka Ilona , Puzule Anita
Published: December 2021

The problem of the study is that Latvian citizens often express dissatisfaction with vehicle registration prices, speculating that these services are available at lower prices in the neighbouring countries – Lithuania and Estonia. The aim of the research: to compare and analyse vehicle registration services in the Baltic States in order to provide suggestions for the improvement of the services. The research uses general scientific research methods: the monographic and descriptive methods, the document analysis method, the comparative analysis method, the horizontal analysis, the ranking method, the logical construction method and the graphical method. Based on the cases analysed, the authors conclude that vehicle registration costs are the lowest in Lithuania, yet these costs may depend on factors such as vehicle age and technical parameters, so not always the cheapest price is reported in Lithuania. Vehicle registration costs in Estonia, regardless of any parameters, for all light vehicles are the same at 192,00 euro. The authors compared and analysed vehicle registration services in the Baltic States, evaluated the price of services and the elements included in them. The study shows that when receiving vehicle registration services in the Baltic States, the conditions and price for receiving them differ. It is mainly influenced by the tax policies and pricing strategies of each country.

AN INVESTIGATION OF RESIDENTS’ PERCEPTIONS OF POSITIVE FESTIVAL IMPACTS, COMMUNITY ATTACHMENT AND WELL-BEING: A STUDY ON THE JAMESON FESTIVAL, VICTORIA FALLS, ZIMBABWE
Authors: Banga Cathrine , Kilic Hasan , Musarapasi Stewart
Published: December 2021

The Study aims to examine residents’ perception of positive festival impacts, social cohesion and cultural benefits on the relationship between community attachment and well-being. An integration of the Social Exchange and Affect Theories are employed to develop and test a conceptual model that test the interrelationships. The quantitative research approach is used to conduct the study on resident attendees of the Jameson Festival in Victoria Falls, Zimbabwe. Via the convenience sampling technique data are collected. Results of the study indicate that festivals foster community cohesiveness and community attachment. They also show that the perceived positive festival impact: community cohesiveness is strongly related to community attachment and well-being; community attachment mediates the relationships. Contrarily, though the relationship between festival cultural preservation and community attachment was partially supported, there was no significant association to well-being. The theoretical implications of the study lay mainly on the introduction of a new theory to the festival body of studies and the study’ findings shed light and direction on practical implications and future directions for festival organizers and scholars

Authors: Gaile Samanta , Dembovska Iveta , Silicka Inese , Teirumnieka Ērika
Published: December 2021

The consumption of functional food is increasing in almost all industrialized countries, not only because of an aging population but also because of a more enthusiastic lifestyle, which makes meeting the nutritional requirements more difficult. In part, the transition to processed, easily packaged and pre-cooked foods is considered to be a response to long working hours. It resulted in an increased demand for ready-to-eat foods in recent years and it is expected to continue growing. The aim of the research is to study and analyse the need for extruded field bean flour food products in the market. Methods used in the research – monographic, synthesis, statistical analysis methods. The research developed proposals for the sale of extruded field bean flour as a food raw material in different markets.

Authors: Rivza Baiba , Plūmīte Uldis
Published: December 2021

Amusement parks have grown rapidly in Latvia over the last 20 years. The development of Latvian amusement parks is determined by several factors related to the economic, political, geopolitical and international market situation. According to the CSB data, the country has a population of 1.9 million and a total of 14 amusement parks or companies providing attractions and entertainment. Part of the problem that the authors emphasize in the paper is that in Latvia, data on amusement parks are not collected separately, but are included in overall data on the tourism industry. This topic has been little studied in all Baltic countries. The topicality of the research relates to the future directions of sustainable development of Latvian amusement parks, which would add value to the growth of this industry. The aim of the research study is to determine the possible directions of development of amusement parks and their main influencing aspects, which determine the future development of these aspects.

The young personâs guide to the PDB
Authors: Minor Wladek , Dauter Zbigniew , Jaskolski Mariusz
Published: December 2021

The Protein Data Bank (PDB), created in 1971 when merely seven protein crystal structures were known, today holds over 120,000 experimentally-determined three-dimensional models of macromolecules, including gigantic structures comprised of hundreds of thousands of atoms, such as ribosomes and viruses. Most of the deposits come from X-ray crystallography experiments, with important contributions also made by NMR spectroscopy and, recently, by the fast growing Cryo-Electron Microscopy. Although the determination of a macromolecular crystal structure is now facilitated by advanced experimental tools and by sophisticated software, it is still a highly complicated research process requiring specialized training, skill, experience and a bit of luck. Understanding the plethora of structural information provided by the PDB requires that its users (consumers) have at least a rudimentary initiation. This is the purpose of this educational overview.
Tackling the problem of HIV drug resistance
Authors: T. Weber Irene , W. Harrison Robert
Published: December 2021

The virally-encoded HIV-1 protease is an effective target for antiviral drugs, however, treatment for HIV infections is limited by the prevalence of drug resistant viral mutants. In this review, we describe our three-pronged approach to analyze and combat drug
resistance. Understanding the molecular basis for resistance due to protease inhibitors is a key initial step in this approach. This knowledge is being employed for the design of new, improved inhibitors with high affinity for resistant mutants as well as wild type enzyme. In parallel with experimental studies of diverse mutants and inhibitory compounds, we are developing efficient algorithms to predict drug resistance phenotype from genotype data. This approach has important practical applications in the clinic where genotyping is recommended for individuals with new infections.

Adventures in cooperativity
Authors: Derewenda Zygmunt S.
Published: December 2021

Macromolecular X-ray crystallography has undergone a dramatic and astonishing transformation since its inception in mid 1950s, almost exclusively owing to the developments in three other fields: computer science; synchrotron radiation; and molecular biology. The process of structure solution from a single crystal, provided the quality of diffraction data is adequate, has been shortened from many years to hours, if not minutes. Yet, in spite of the exponential increase in the available structural information (~120,000 structures in the Protein Data Bank today), many fundamental problems continue to be the subject of scientific controversy. This article contains personal recollections of the author, pertaining to two research projects â conducted nearly four decades apart â both of which touch upon such long standing discussion of the Monod-Wyman-Changeux theory of cooperativity (or âconformational selectionâ) vs the Koshland-Nemethy-Filmer theory of âinduced fitâ. It is dedicated to Dr. Alexander Wlodawer on his 70th birthday, with best wishes of continuing success.

Type II and type V CRISPR effector nucleases from a structural biologistâs perspective
Authors: Fernandes Humberto , Pastor Michal , Bochtler Matthias
Published: December 2021

The type II and type V CRISPR effector nucleases Cas9 and Cpf1 are âuniversal” DNA endonucleases, which can be programmed by an appropriate crRNA or sgRNA strand to cleave almost any DNA duplex at a preselected position (constrained only by short, so-called PAMs). In
this review, we briefly introduce CRISPR bacterial adaptive immunity as the biological context in which Cas9 and Cpf1 proteins operate, and then present the structural insights that have been obtained in the last two or three years that illustrate the mode of operation of these proteins. We describe the R-loop structures at the core of the Cas9 and Cpf1 complexes, and the structure of the 5â- or 3â-handles that help anchor the nucleic acid complexes to the proteins in a manner that is independent of the target sequence. Next, we describe the molecular architecture of the Cas9 and Cpf1 proteins. We illustrate how Cas9 and Cpf1 proteins scan double stranded DNA for so-called protospacer associated motifs (PAMs), we explain how the phosphate loop (PLL) and basic helix (BH) promote the separation of target and non-target DNA strands and the formation of hybrids between crRNA or sgRNA and the target strand of DNA. We also describe the current understanding of the catalytic mechanisms of RuvC and HNH domains, and a possible, but still very uncertain catalytic role of the Nuc domain. At the end of the review, we briefly summarize key developments that have initiated the field of genomic engineering using Cas9 or Cpf1 nucleases..

Published: December 2021

Despite the massive disease burden worldwide caused by parasitic nematodes and other infectious pathogens, the molecular basis of many infectious diseases caused by these pathogens has been unduly neglected for a long time. Therefore, accelerated progress towards novel therapeutics, and ultimately control of such infectious diseases, is of crucial importance. Capitalising on the wealth of data becoming available from proteomic and genomic studies, new protein targets at the pathogen-host interface can be identified and subjected to protein-based explorations of the molecular basis of pathogen-host interactions. By combining the use of systems and structural biology methodologies, insights into the structural and molecular mechanisms of these interactions can assist in the development of therapeutics and/or vaccines. This brief review examines two different proteins from the body wall of blood flukes â annexins and the stress-induced phosphoprotein 1 â both of which are presently interesting targets for the development of therapeutics.
The remarkable solubility-enhancing power of Escherichia coli maltose-binding protein
Authors: Waugh David S
Published: December 2021

A common problem encountered during the production of recombinant proteins, particularly in bacteria, is their tendency to accumulate in an insoluble and inactive form (i.e., as inclusion bodies). Although sometimes it is possible to convert the aggregated material into native, biologically active protein, this is a time-consuming, costly, and uncertain undertaking. Consequently, a general means of circumventing the formation of inclusion bodies is highly desirable. During the 1990s, it was serendipitously discovered that certain highly soluble proteins have the ability to enhance the solubility of their fusion partners, thereby preventing them from forming insoluble aggregates. In the ensuing years, Escherichia coli maltose-binding protein (MBP) has emerged as one of the most effective solubility enhancers. Moreover, once rendered soluble by fusion to MBP, many proteins are able to fold into their biologically active conformations. This brief review article focuses on our current understanding of what makes MBP such an effective solubility enhancer and how it facilitates the proper folding of its fusion partners.
Introduction to high-resolution cryo-electron microscopy
Authors: Czarnocki-Cieciura Mariusz , Nowotny Marcin
Published: December 2021

For many years two techniques have dominated structural biology â X-ray crystallography and NMR spectroscopy. Traditional cryo-electron microscopy of biological macromolecules produced macromolecular reconstructions at resolution limited to 6â10 Ă. Recent development of transmission electron microscopes, in particular the development of direct electron detectors, and continuous improvements in the available software, have led to the âresolution revolution” in cryo-EM. It is now possible to routinely obtain near-atomic-resolution 3D maps of intact biological macromolecules as small as ~100 kDa. Thus, cryo-EM is now becoming the method of choice for structural analysis of many complex assemblies that are unsuitable for structure determination by other methods.
Designing a synchrotron micro-focusing beamline for macromolecular crystallography
Authors: Grochulski Paweł , Cygler Mirosław , Yates Brian
Published: December 2021

After a successful 10 years of operation, the Canadian Macromolecular Crystallography Facility 08ID-1 beamline will undergo an upgrade to establish micro-beam capability. This paper is mostly focussed on optics and computer simulations for ray tracing of the beamline. After completion, the focussed beam at the sample will have a much smaller size of 50 Ă 5 Îźm2 (H x V), allowing measurement of X-ray diffraction patterns from much smaller crystals than possible presently. The beamline will be equipped with a fast sample changer and an ultra-low noise photon counting detector, allowing shutter-less operation of the beamline. Additionally, it will be possible to perform in-situ room-temperature experiments.
Evaluation of the correlation between perfusion index and prognosis in patients with chronic obstructive pulmonary disease
Authors: DEMİR Mehmet , CANDER Basar , AYVACI Barış Murat
Published: December 2021

Objectives: This study aims to investigate whether perfusion index (PI) values, which are measured non-invasively, affect emergency management, especially in hospitalization and discharge decision in patients with Chronic Obstructive Pulmonary Disease (COPD).
Methods: Patients who were admitted to the emergency department of Okmeydanı Training and Research Hospital with a COPD exacerbation in 3-months period and who volunteered to participate were included in the study. Vital parameters and PI values of the patients at the time of admission, at the first, second and third hour of the admittance and at the time of hospitalization (in the case of hospitalization) were recorded. The patients were treated for COPD exacerbation according to the Global Initiative for Chronic Obstructive Lung Disease 2011 guide and the decision of discharge, hospitalization in the emergency department, andhospitalization in the intensive care unit was taken based on the relevant guideline.
Results: A total of 57 patients were included in the study. Of the patients, 45 (78.9%) were male. The mean age of the patients was 65.65 ± 9.90 years. There was no statistically significant difference in arrival vital parameters and PI in terms of the gender (p > 0.05). The change between PI values at the time of admission and the first hour in the patients admitted to intensive care unit was found to be significantly lower compared to patients who were hospitalized in the emergency department or discharged (p = 0.035; p = 0.033). The difference between the PI values at the time of admission and at the third hour of the follow up of the discharged patients was found to be significantly higher compared to the hospitalized patients (p = 0.035). There was no statistically significant difference between the arrival PI measurements in terms of the presence of comorbid diseases (p > 0.05).
Conclusions: Considering the hourly changes, the PI values of patients admitted to the emergency department with COPD exacerbation may be helpful in predicting the decision of discharge, hospitalization in the emergency department or intensive care unit.

Authors: YARADILMIŞ Yüksel Uğur , OKKAOGLU Mustafa Caner , ÖZDEMİR Erdi , ATEŞ Ahmet , DEMİRKALE İsmail , ALTAY Murat
Published: December 2021

Objectives: Limited data is available regarding the quality of life of hip fracture patients following surgery. This study examined the mid-term quality of life of hip fracture patients and compared these patients with healthy elderly patients devoid of hip fractures.
Methods: A total of 103 patients (aged > 65 years) with pertrochanteric femoral fractures were treated with proximal femoral nail surgery in our clinic between January 2012 and December 2016. A healthy control group (n = 100) was demographically matched to the patients. The final follow-up visit included their Harris Hip Score and completion of a Short Form-36. The eight sub-parameters from the Short Form-36 form were also assessed.
Results: The mean follow-up time for the patients was 36.4 ± 12.3 (range, 24-72) months. The mean Charlson comorbidity score for the patient group was 4.4 ± 2.1 and the mean Harris Hip Score was 77.24 ± 10.2. The comparison of the Short Form-36 sub-parameters revealed that the quality of life of the patient group was found to be lower than that of the control group for the following parameters physical function, physical roles, vitality, and social function (p < 0.05).
Conclusions: Even if the fracture had healed of patients with hip fractures, QoL related to physical and social functions was not improved accordingly, new healthcare policies should be developed for these patients based on the premise that their physical capacity may not be fully regained. Moreover, the importance of hip fracture prevention was demonstrated by this study.

Living at the Margins: Black Feminist Pedagogy as Transformative Praxis During the 1980s-1990s and Epistemic Exclusion in the 21st Century—Where Do We Go Now?
Authors: Mogadime Dolana
Published: December 2021

In this essay I argue that Black women who teach Black feminist pedagogy experience “epistemic exclusion” (Buchanan, 2020) while advocating for the intersections between three disparate contexts: their activism in their communities, the women’s movement, and their work as educators in postsecondary settings. The period examined is the 1980s–1990s. I consider the institutional challenges and limitations Black women have undergone as knowledge producers and teachers. While pushing the boundaries erected between university settings and the Black liberation movement taking place in their communities (Joseph, 2003), they were limited to a precarious status as Black women teaching within White-male dominated institutions. The trailblazing theoretical pedagogical insights Black feminists have advanced in their work as educators in postsecondary settings is discussed at length. Additionally, connections are made to the present-day struggle among Black feminists for inclusion within contemporary educational contexts (Evans-Winters & Piest, 2014; Mogadime, 2002, 2003; Wane, 2009, 2011).
Between the Tides: Developing an Indigenous-Informed Cultural Safety Training Impact Assessment Survey Tool for Post-Secondary Institutions on Vancouver Island, BC
Authors: Whitinui Paul , Dick Skip , Hancock Rob , Alan Billie , Loppie Charlotte , Erb Tara , Duerksen Rebecca , Baldwin Cortney
Published: December 2021

This paper highlights the development of an Indigenous Cultural Safety Training (ICST) impact assessment survey tool working in collaboration with Indigenous leaders, Elders, faculty, staff, and students from across four post-secondary institutions on the traditional lands of the Songhees, Esquimalt and WSÁNEĆ Peoples on Vancouver Island, British Columbia. What emerged from a series of Indigenous-led workshops was the development of an ICST impact assessment survey tool to measure the impact of the training as well as for ICST participants to reflect on their own cognitive and behavioural change within their practice over a 12-month period. In addition, a validation process with ICST experts, facilitators, staff, faculty, Elders, and participants was carried out to help refine the proposed co-constructed assessment variables, statements, and questions underpinning the survey tool. The finalized ICST impact assessment survey tool will not only improve the quality of ICST in post-secondary settings, but will also enable staff, faculty, and leaders to reflect on how the ICST improves their personal and professional practice working with Indigenous students in these settings.
Intersections between Human Trafficking and Education: Toward New Research Agendas
Authors: Spires Bob
Published: December 2021

Human trafficking is a social issue that has gained attention in the media and in scholarship. A growing number of anti-trafficking organizations and actors have begun to use education to diverse ends. Although not often associated with human trafficking, education is a common tool used by anti-trafficking organizations, whether as a prevention tool to reduce the vulnerability of people at-risk of trafficking, or as a service to trafficking survivors to improve their lives. Lack of access to education, or to quality education, is also a factor in exposure to human trafficking, whether that be in terms of debt bondage, domestic servitude, forced labor, child marriage or other issues related to human trafficking. More explicit connections need to be made between the work being done in anti-trafficking spheres and the scholarship of education in order to better understand how to improve the quality and effectiveness of education-related efforts. This essay explores the connections between human trafficking and education.
English Language Learners, Labels, Purposes, Standard English, Whiteness, Deficit Views, and Unproblematic Framings: Toward Southern Decoloniality
Authors: Chaka Chaka
Published: December 2021

This paper argues for revisiting ways in which English Language Learners (ELLs), and the learner labels attributed to them, are negatively, racially, and pathologically framed and constructed based on, putatively, their English language competence, or their lack of it. It contends that this framing tends to give rise to a raciolinguistic profiling of these learners, as they end up being classified by their race, pan-ethnicity, nationality, immigrant/refugee status, regionality, and at times, by their skin color, in addition to their language abilities. This raciolinguistic framing often engenders other framings such as White, deficit, and poverty framings, and sub-framings like an othering framing (e.g., the racial others and the linguistic others). These framings, together with the normative ways in which ELLs’ language problems are constructed, have been characterized in this paper as misframings. Additionally, employing southern decoloniality, the paper problematizes and critiques the way ELLs are constructed and labeled, and the appropriation of Standard English (SE) as the sole touchstone of acceptable English in the midst of the other varieties of SE and of pluriversal speakers of English. Finally, the paper calls for the provincialization/localization or the deparochialization of English in keeping with its southern decolonial approach.
How COVID-19 Has Exacerbated Inequality in Higher Education in Brazil
Authors: Pinto Francisco
Published: December 2021

Drawing on educational census data and a review of news articles and higher education policies in Brazil, this article examines the impact of COVID-19 on the access and retention of the low-income Brazilian population in higher education. Guided by the question, “What is the impact of COVID-19 on the most vulnerable population in Brazil in terms of access to, and retention in higher education?”, the paper is structured in two sections: the first offers a short historical overview of Brazilian higher education; the second examines the impact of the pandemic on student retention in higher education, looking at factors such as social isolation, job and income precarity, use of Information and Communication Technologies (ICT), internet access, and technological resources.
I argue that distance education offered by private higher education institutions benefits the privileged students and that the effects of the pandemic are detrimental to the socially disadvantaged students since those who are in public universities do not always have access to technology, and those who study in private universities feel the impact of not being able to pay tuition fees, besides the loss of several jobs in different sectors. In conclusion, I recommend policy initiatives to improve access to higher education.

This essay, part of a larger study, speaks to the Syrian Diaspora’s lived reality in Canada, a complex topic that delves into issues of dislocation, displacement, loss, exile, identity, resilience and a desire for belonging (Alatrash, 2019; 2020). The study seeks to better understand these issues and the lived experience and human condition of the Syrian Diaspora in Canada. I engage autoethnography as a research methodology and as a method as I think and write from my own personal experience as a Syrian immigrant so that I could better understand the Syrian refugee’s lived experience (Alatrash, 2019). My research participants were three Syrian refugee families in Calgary, in addition to myself as an autoethnographer. As I autoethnographically analyzed, presented, and interpreted the stories of the three families, I identified a number of themes (Alatrash, 2019; 2020); this essay addresses one of these themes: On creating new possibilities: Activating and actualizing the Third Space (Alatrash, 2019).

Published: December 2021

[English]: This study aims to examine the effectiveness of the problem-based calculus learning model (PB-CLM) towards students’ higher-order thinking skills (HOTS). PB-CLM is a modification of problem-based learning’s (PBL) syntax. It was a quasi-experimental with a group pretest-posttest design involving 351 11th-grade students as the population. Seventy-one students of two classes were randomly selected as a sample. Data was collected through pretest and posttest developed from three aspects of HOTS; analysis, evaluation, and synthesis. To determine the effectiveness of PB-CLM, paired sample t-test and independent sample t-test with a significance level of 5% (α = 0.05) were used. The results show that students’ activities during the learning process in PB-CLM has a positive effect on increasing their HOTS (mean difference = 30.141; sig one-tailed = 0.000). Furthermore, there was no significant difference in HOTS among male and female students, both at the pretest and posttest (mean difference = 0.81731; sig.= 0.295). Likewise, the increase in HOTS scores (posttest-pretest) did not differ significantly between gender (mean difference = 0.88141; sig. one-tailed = 0.740).

Data penelitian dikumpulkan dengan menggunakan pretest dan posttest yang dikembangkan dari 3 aspek HOTS; analisis, evaluasi, dan sintesis. Untuk mengetahui keefektifan PB-CLM digunakan paired sample t-test dan independent sample t-test dengan taraf signifikansi 5% (α = 0,05). Hasil analisis menunjukkan aktivitas siswa selama pembelajaran dengan PB-CLM efektif dalam meningkatkan HOTS (mean difference = 30,141; sig.one-tailed = 0,000). Lebih lanjut, tidak ditemukan perbedaan yang signifikan antara HOTS siswa laki-laki dan perempuan, baik pada pretest maupun posttest (mean difference = 0,81731; sig.= 0,295). Begitu pula peningkatan skor HOTS (posttest-pretest) juga tidak berbeda signifikan antara siswa laki-laki dan perempuan (mean difference = 0,88141; sig. one-tailed = 0,740).

Autoconcepto del profesorado rural, urbano y privado y rendimiento académico de sus estudiantes durante la pandemia
Authors: Ibarra Aguirre Enrique , Acevedo Pedro Macias
Published: December 2021

Su objetivo es describir el autoconcepto del profesorado de educación básica primaria públicas urbanas y rurales y de colegios privados, así como sus vínculos con el promedio de calificaciones grupal de los estudiantes a su cargo, durante la pandemia por la COVID-19. Es un trabajo cuantitativo, descriptivo y de corte transversal. Participa una muestra de conveniencia conformada por 115 docentes del Estado de Sinaloa, México; 88 (83.8%) son del sexo femenino y 17 (16.2%) del masculino. Fue utilizado el Cuestionario de Autoconcepto Forma-5. La dimensión emocional presenta puntajes menores, pero con más declive en las mujeres. El grupo de edad de 41-46 años expresa un autoconcepto multidimensional mayor que los otros grupos. Los profesores de escuelas urbanas públicas, presentan medias del autoconcepto más altas, que los de colegios y de escuelas rurales. El rendimiento académico es más alto en escuelas privadas, seguido de las urbanas y las rurales. Se percibe asociación entre el autoconcepto académico y el rendimiento académico, pero no es significativa. Los hallazgos impelen al sistema educativo a brindar acompañamiento psicológico a los profesores, para su bienestar en tiempos y experiencias difíciles y para que ofrezcan el mejor servicio educativo, en beneficio del logro educativo del estudiantado.
Instrumentos pedagógicos de la alternancia y sostenimiento de la escolaridad en tiempos de COVID-19
Authors: Miano Maria Amalia
Published: December 2021

El cierre de escuelas en el contexto de la pandemia ocasionada por el virus SARS COV2 no contempló la diversidad de situaciones socioeconómicas y geográficas de las familias que habitan en ámbitos rurales. La mayor parte de estas familias no cuentan con conexión estable y de calidad a Internet como recurso para dar continuidad a la escolarización de sus hijos a través de la virtualidad. El objetivo de este trabajo es demostrar que, a pesar de las dificultades mencionadas, los instrumentos pedagógicos de la alternancia han permitido dar un sostén a la continuidad pedagógica de los estudiantes de estas escuelas ya que se contaba con una experiencia de trabajo previa vinculada a la autogestión y el acompañamiento de las familias. Metodológicamente, analizamos los resultados de una encuesta aplicada a escuelas rurales de alternancia de la provincia de Buenos Aires para conocer lo ocurrido durante la pandemia. Complementamos este análisis con la codificación de entrevistas realizadas a actores vinculados con estas escuelas. Concluimos en la importancia de considerar a la autogestión y el acompañamiento de las familias no únicamente como una solución circunstancial para un momento específico sino como parte de un proyecto educativo y político para las comunidades rurales.

El objetivo de esta investigación es analizar las representaciones de profesores de primarias rurales y urbano-marginadas sobre su trabajo durante la pandemia por COVID-19 en el inicio del ciclo escolar 2020-2021. El referente teórico que orienta el estudio es la concepción de trabajo docente del interaccionismo sociodiscursivo, particularmente las dimensiones de trabajo representado y prescrito. Como parte de la metodología se aplicó un cuestionario con preguntas abiertas y de opción múltiple a 24 profesores de dos estados mexicanos: San Luis Potosí y Veracruz. Los resultados muestran que, para los profesores participantes, la educación a distancia aumenta el rezago educativo o dificulta el aprendizaje. Además, permiten identificar las dificultades previstas para el nuevo ciclo escolar (conexión a internet, explicación de contenidos y la comunicación con las familias) y reconocer que WhatsApp se convirtió en la principal alternativa para el desarrollo de las clases síncronas, el envío de tareas y la comunicación con los estudiantes y sus familias.

Este artículo tiene como objetivo exponer el estado del arte de los recursos digitales y tecnológicos utilizados en los procesos de enseñanza y aprendizaje en las escuelas rurales. Estos han de promover la transformación digital y un modelo educativo inclusivo, flexible, que permita la cooperación y una educación abierta. Su uso ha de contribuir a la mejora de la didáctica multigrado y a reducir la brecha digital. Se realiza una revisión sistemática a nivel internacional de los artículos publicados en los últimos diez años en revistas indexadas en las bases de datos Scopus y Web of Science. De un total de 671 trabajos identificados en el campo de la educación rural, se analizaron los referentes a los recursos digitales en base a unos criterios de selección (N=18). Los primeros resultados muestran la necesidad de crear recursos que permitan el trabajo multigrado y en línea, desarrollando la competencia digital de los alumnos, teniendo en cuenta la idiosincrasia de las escuelas rurales. También el establecimiento de redes de apoyo al profesorado, compartiendo recursos y mejorando la formación permanente en tecnologías emergentes para la innovación educativa. Las conclusiones refieren a oportunidades relativas al uso de recursos educativos abiertos y plataformas de crowdsourcing.
