B a c k g r o u n d . The article examines the appearance, essence and formation of the concept of "echo chamber" in the field of philosophy. The main interpretations and practical aspects of the application of this concept by representatives of the philosophical community are considered. Considering the lack of an established version of the concept of "echo chamber", an attempt was made to define its meaning by analogy with the already established interpretation of a physical analogue, namely, a resonator. The appropriateness of such an analogy is justified. The specifics of the operation of echo chambers are considered by analogy with the operation of the resonator and its associated phenomena. The phenomenon of "intellectual inbreeding" ("geistiger Inzucht") described by H. Franke is considered. M e t h o d s . The theoretical and methodological foundations of the research are based on the principles of scientific objectivity, impartiality and systematicity. During the research, general scientific, philosophical, and special methods of studying social and political phenomena were used, including general methods of analysis, synthesis, and comparative methods. R e s u l t s . The author's understanding of the meaning of the concept of "echo chamber" and the prerequisites for its stability, which are determined by the properties of human consciousness, namely: "comfort zone", "clipping of thinking" and the principle of "own-foreign" are offered. The appropriateness of consideration and the main properties of the echo chamber as a technology of effective communication influence are substantiated. Among the methods of destroying echo chambers, the development of critical thinking skills and digital literacy, compliance with the principles of diversification of information sources and "range of reasonable alternatives", the occurrence of cognitive dissonance, as well as the phenomenon of emotional resonance are considered. C o n c l u s i o n s . Echo chambers pose a significant threat both to the harmonious development of the human personality and to the stable existence of civilized societies. Methods of countering echo chambers require further development and dissemination in society.
NATO’s Securitisation of Climate Change in the Arctic
Authors: Balkan Şahin Sevgi , Çetiner Özge
Published: April 2024

This study analyses how and why the North Atlantic Treaty Organisation (NATO) securitises climate change in the Arctic. The study recognises that climate change has not only endangered the environmental security of the Arctic but has also intensified geopolitical competition over the region’s resources and trade routes as a threat multiplier. Regarding the impact of the changing structure of the region from the “cooperation front” to the “competition area”, the study reveals that NATO considers climate change as a part of the collective defence dimension of its organizational identity, along with increasing geopolitical competition, to develop an integrated approach in its Arctic policy. Drawing on the Copenhagen School and social constructivism, the study presents that NATO resorts to securitisation discourses that concretise the threat to address climate change within the scope of its organizational identity.

Published: April 2024

Background. The outcome of complex treatment of implant-associated infection (IAI) depends on various factors, but one of the most important is the etiology of the inflammatory process. Treatment of orthopedic infection caused by Gram-negative microorganisms in general and representatives of the family Enterobacteriaceae in particular causes many difficulties, one of which is the rapid growth of antibiotic resistance.
Aim of the study — to evaluate the factors affecting the course and prognosis of implant-associated infection caused by Klebsiella spp.
Methods. We performed a retrospective analysis of case histories of 85 patients who underwent treatment of IAI caused by Klebsiella spp. in the clinical departments of the center from January 1, 2017 to December 31, 2021. According to the results of the telephone survey, the patients were divided into 2 main groups depending on the outcome of the 2-year follow-up period determined in accordance with the Delphi criteria.
Results. It was found that the prognosis was significantly worsened by the number of sanitizing surgical interventions in the anamnesis (p = 0.022), the need for sanitizing intervention in the early postoperative period (p0.001) and the presence of Klebsiella spp. growth in postoperative culture tests (p = 0.002), hypoalbuminemia on 7-14 days after the surgery (p = 0.008). The administration of trimethoprim-sulfamethoxazole for the outpatient treament stage significantly improved the outcome (p = 0.038), which is most likely due to a high proportion of polymicrobial associations — 69.5%.
Conclusions. There is a statistically significant direct relationship between the probability of an unfavorable treatment outcome of patients with IAI caused by Klebsiella spp. and the number of sanitizing surgical interventions in the anamnesis, low serum albumin (g/l) on 7-14 days after the operation, revision intervention in the early postoperative period, positive growth of Klebsiella spp. in postoperative culture tests. The probability of a favorable outcome was increased by the prescription of trimethoprim-sulfamethoxazole for oral administration at the outpatient stage.

Published: April 2024

In recent years, epidemiological studies have increasingly recognized the significance of heavy metals as an important pathogenetic factor in many gastrointestinal diseases, particularly those associated with in gut microbiota functions. The toxicity of heavy metals towards essential intestinal microflora goes beyond causing dysbiotic disorders; it can also exacerbate intestinal infections, alter metabolic processes, and influence the development of antibiotic resistance. Since the negative effects of heavy metals are environmental in nature, there is a need to systematize the etiological role between the effects of heavy metals on the microbiome and possible nosological conditions for a more accurate approach to treatment and further research. Given the environmental origins of the abovementioned effects, there is a need to systematize the impact of heavy metals on the microbiome and their role in disease development to improve approaches to treatment and further research.
We aimed to analyze the latest scientific evidence on the associations between heavy metals exposure and the intestinal microbiome and its role in the development of gastrointestinal disorders. For this scoping review we used PubMed and eLIBRARY.ru databases. We searched for keywords: «gut microbiota», «intestinal infections» (disorders), «antibiotic resistance» «heavy metals» in both Russian and English. Based on the research reviewed in this study, we can infer that heavy metals act as exogenous toxicants contributing to the development of dysbiotic, metabolic and trophic disorders of the gastrointestinal tract. They also influence the progression of infections and the development of antibiotic resistance in bacteria. Further studies should focus on exploring the toxicity of heavy metals in relation to specific populations of intestinal flora and associations with metal and antibiotic resistance. It is important to consider the therapeutic potential of microbiome modulation in the management of gastrointestinal diseases.

Authors: Vorontsova Tatyana Sergeevna , Vasilyeva Natalia N. , Isakova Larisa S.
Published: April 2024

BACKGROUND: Stress is an integral part of life in both humans and animals. Up to 70% of the Russian population have reported a certain degree of stress associated with approximately 80% of diseases. This heavy burden of stress explains a significant body of research on the issue of stress and its associations with health indicators.
AIM: To study the effects of rotating electric fields on blood metabolic parameters in experimental animals with different levels of resistance to stress.
MATERIALS AND METHODS: A total of 54 non-inbred white male rats comprised the sample. We measured serum levels of 11-hydroxycorticosteroids, glucose, C-reactive protein, total sialic acids and the activity of hepatospecific enzymes, such as aspartate transferase, alanine transferase, and alkaline phosphatase at the 10th and the 20th day of exposure to a man-made rotating electric field and in the non-exposed control group. By the level of resistance to stress all rats were divided into stress-resistant, stress-unresistant and ambivalent groups using the "open field" method.
RESULTS: On the 10th day of exposure, the levels of 11-hydroxycorticosteroids, glucose, C-reactive protein, total sialic acids increased in all three groups of animals. The activity of aspartate transferase, alanine transferase, and alkaline phosphatase also increased in all rats. On the 20th day, the studied parameters remained elevated compared to the control group. The most pronounced changes were observed in the group of stress-unresistant individuals.
CONCLUSION: Our results demonstrate significant effects of rotating electric fields on blood metabolic indicators in rats. The degree of change depends on individual level of stress resistance.

Published: April 2024

BACKGROUND: Epithelial barrier dysfunction, including their permeability increment, is supposed to be a pathogenetic link in the development of various immunoinflammatory diseases, including Crohn’s disease and axial spondyloarthritits. Endothelial permeability regulation is provided by both intercellular contacts and endothelial glycocalyx.
AIM: To study the microcirculatory state by measuring the endothelial glycocalyx thickness in patients with axial spondyloarthritits associated with Crohn’s disease. To identify an association between the endothelial glycocalyx thinning and the epithelial permeability severity in patients with Crohn’s disease, axial spondyloarthritits and their combination.
MATERIALS AND METHODS: 12 patients with axial spondyloarthritits associated with Crohn’s disease (group A), 22 patients with idiopathic axial spondyloarthritits (group B), 24 patients with Crohn’s disease (group C) and 16 healthy individuals (group D) were examined. The endothelial glycocalyx thickness was assessed in the sublingual region using dark-field microscopy. Fecal calprotectin and fecal zonulin was studied.
RESULTS: A statistically significant increase in the perfused boundary region high flow was found (p = 0.001), as well as the MicroVascular Health Score (p = 0.004) in group A compared with the control. In Group A, a positive correlation between perfused boundary region high flow and scores Ankylosing Spondylitis Disease Activity Score, Bath Ankylosing Spondylitis Disease Activity Index, Bath Ankylosing Spondylitis Metrology Index 10 (p 0.05) was found; perfused boundary region 5–9 mµ correlated positively with the fecal calprotectin (p = 0.007). Perfused boundary region high flow measurement provides 77.1% accuracy for correct classification of axial spondyloarthritits associated with Crohn’s disease and idiopathic axial spondyloarthritits (p = 0.010). In group C, a positive correlation between fecal zonulin and perfused boundary region 5–9 mµ, 10–19 mµ, 5–25 mµ (p 0.05) was also found.
CONCLUSIONS: The findings suggest that the patients with axial spondyloarthritits associated with Crohn’s disease have endothelial glycocalyx impairment; the detection of these abnormalities may be useful in assessing the disease integral activity and in the differential diagnosis of axial spondyloarthritits associated with Crohn’s disease and idiopathic axial spondyloarthritits. Further studies of microcirculation will allow better understanding of spondyloarthritis and inflammatory bowel diseases pathogenesis and improve the management of patients with these diseases.

Published: April 2024

The categorization of Cali as a special district has led to intricate debates in different fields, including the legal, political-administrative, and social spheres. However, primarily, the issues revolve around governance guarantees. It is argued that this pivotal concept contributes to understanding efficient and effective public management. This article aims to analyze the effects of the Special District of Santiago de Cali political-administrative division on governance in the territories. The employed methodology combines social science hermeneutics and normative analysis inherent in legal hermeneutics. This article presents two major challenges to governance: the social, political, environmental, and economic heterogeneity of the territories, and their ability to adapt to institutional change. The new district localities must consider the socio-economic and environmental characteristics, as well as the capacity for coordination and organization, in terms of public management, within the city.

In 1937, the elixir sulphanilamide disaster was one of the mass poisonings. It occurs due to the presence of the diluent diethylene glycol in the elixir preparation of sulphanilamide. Because of its therapeutic use, around 100 patients died. In response to the calamity, Federal Food, Drug and Cosmetic Act was passed in the year 1938 by U.S congress and this ensured the proof of safety before the drug comes to market. The similar incident occurred for thalidomide in late 1950s and early 1960s when the drug was used for the treatment of nausea in pregnant women and resulted in children with birth defects. The development of drugs is a complex and costly process and it takes around 10-15 years for the drug to develop. Because of these reasons, the development of generic drugs is essential and this review will deal about the use of generic drugs and also its advantages with limitations.

Published: April 2024

Abstract: The article attempts to reconstruct the biographies of two prominent historical figures of the first decades of the XX century – Counts Alexander and Mstislav Tolstoy, older brothers of the writer A.N. Tolstoy. Having begun their career path in Samara and in the Samara province, where both alternately headed the Samara district nobility, they made excellent careers (one of the brothers met the 1917 revolution as governor of Vilna, and the other as vice-governor of St. Petersburg), many and productive worked for the benefit of their hometown of Samara and the country as a whole, but after the revolution they were forgotten and erased from Russian history, a slow return to which began about three decades ago, but has not yet fully taken place. This article is an attempt at such a personal return, where, on the basis of rare and unique documents from the family collections of the descendants of Count Tolstoy, memoirs, newspaper publications, etc., their biographies are restored, including both official, public, and personal, family moments. The attempted biographical reconstruction is interesting and significant both in historical and local history terms, and in historical and literary terms – as a context for the historical trilogy of the younger brother of the heroes of this article by A.N. Tolstoy – the trilogy «The Road to Calvary».

Published: April 2024

This study aims to investigate the combined impact of governance regulations and controls on the accuracy of financial reporting. The study also sought to determine how the application controls for the accrual basis affected the link between governance rules and financial reporting quality. A questionnaire research methodology was used to evaluate the study's postulated model. Only 242 of the 348 completed surveys were returned and could be used. The partial least squares method was applied to structural equation modelling. The statistical results confirmed the influence of application constraints on governance norms on the calibre of financial reporting. The influence of governance rule application controls on the calibre of financial reporting was also shown to be mitigated by application controls on an accrual basis. This study, like others has limitations on the variables, years, nation and sample. As a result, several restrictions and recommendations for further research investigations are given at the end of this study. Additionally, the market might use the study's conclusions to help management strengthen their financial reporting inadequacies. This is a rare and unique empirical study that examines the relationship between financial reporting quality and governance rules application controls (GRAC) and takes into account both the influence of GRAC on financial reporting quality and the moderating effect of accrual basis application controls (ABAC).

Authors: Bhekti Fadilla Nanda , . Siti
Published: April 2024

Information literacy is an essential skill in the 21st century. This skill is required for students to find, select, evaluate, and use information they have gathered effectively. The implementation of a specific learning model aids students in developing their information literacy. One of the learning models expected to enhance students’ information literacy is the Reading Concept Mapping-Think, Talk, Write (Remap-TTW). This study aimed to discover the effects of the Remap-TTW learning model on students’ information literacy. This quasi-experiment study used a non-randomized control group pretest-posttest design. The study was carried out in the State Senior High School 1 Kencong, Jember, Indonesia, in the even semester of 2021/2022. The test instrument was in the form of an essay test. Students’ information literacy was measured using numerous indicators: determining the extent of information needed, accessing the needed information, evaluating information and its sources critically, using information effectively to accomplish a specific purpose, and accessing and using information ethically and legally. The scores were analyzed using the normality and homogeneity test, followed by One-Way ANCOVA. The analysis results showed a significance value of 0.000 (P-value < 0.05), signifying different information literacy between students attending learning with three different learning models. The obtained scores were considered significant, indicating that the learning model significantly influences students’ information literacy. Thus, Remap-TTW can be used as an alternative learning model to improve students’ information literacy.

This study aimed to analyze the TPACK (Technological Pedagogical Content Knowledge) profiles of biology teachers in their learning process after participating in numerical taxonomy and its training program. TPACK is a construction of knowledge that must be possessed by teachers in the 21st century. Numerical taxonomy and its training aim to develop biology teachers’ TPACK in the classification of living things. This training equips biology teachers with the knowledge needed to integrate TPACK components into the learning process, including contents related to TPACK and to the classification of living things, especially numerical taxonomy, learning technology, learning strategies, and methods to integrate TPACK into the learning process. This research is a descriptive study in which the data of biology teachers’ TPACK during the learning process were obtained from PaP-eRs and the results of the learning performance assessment. The results showed that biology teachers’ TPACK during the learning process after numerical taxonomy training had good results, and there has been an interactive phase between the TPACK components in the learning process. This is proven by teachers’ ability to develop good PaP-eRs and teachers’ performance based on the learning assessment results. It was further found that the use of technology in the learning process has been optimally applied by teachers. Meanwhile, the delivery of motivation and misconception were less developed by the teachers during the implementation of the TPACK learning process.

This study aims to analyze the mathematical representation ability of junior high school students on plane figures subject in the new normal era. To prevent the spread of Covid-19 in schools, learning was carried out alternately with 50% face-to-face learning and 50% independently at home. This research is a qualitative descriptive study. The subjects of this study were 20 students studying in seventh-grade students, in the second semester, at Dharmasraya West Sumatra for the academic year 2020/2021. The instruments used in this study were tests of students’ mathematical representation abilities and interviews. The indicators measured are visual representation, expression representation, and word representation. Based on the research conducted, it was found that the level of students’ mathematical representation ability was still low (52.65). In general, students still experience problems in using their mathematical representation skills; therefore, students must be able to hone their representation skills in visual, symbol, and verbal representations. Mastering mathematical representation skills can make it easier for students to solve mathematical problems, and there will be fewer conceptual errors. Moreover, it is necessary to conduct additional research to enhance students’ mathematical representation skills.

This study aims to describe the metacognitive self-management of students in developing rigorous mathematical thinking. This study uses a qualitative method with a case study approach. The participants were three students from the thirdlevel mathematics education department, who were selected and made a contract with for real analysis lectures. The first student experienced a significant change from the beginning of the meeting, resulting in the metacognitive self-management process being well-conditioned. He completed the task more confidently than the initial presentation, used several references and sources of information to complete the job, and represented each answer in the form of mathematical symbols. This studentscognitive function appears to be of level-1, with qualitative thinking. For the 2nd student, a change was observed in the learning process and the teacher’s motivation and guidance. The results of the interviews showed that the student applied strategies in completing assignments. He answered them systematically, based on experience, and mastered the prerequisite material. This student showed improved thinking skills related to mastery of concepts from new material, analyzing the problems given, being critical and focused when answering, and looking hard to get maximum evaluation results. This 2nd student entered the level of quantitative thinking with precision. Lastly, in the 3rd student, self-management seems stable, but was still lacking in adjusting the understanding of prerequisites with understanding concepts from new material. The development during the learning process shows that he can activate his mathematical knowledge, compose logical proofs of Real Analysis material problems, and build relationships between prerequisite concepts and new material. This type of student enters the level of abstract relational. The results of the study can be a reference for teachers to determine the learning model and the related instruments, so that they can grow the level of mathematical thinking before, during, and after the learning process.

Analysis of Student Communication in the Discovery Learning Model Using Transcript-based Lesson Analysis
Authors: Irvan Irvani Asep , Agus Dian
Published: April 2024

This study aimed to analyze student and teacher communication in discovery learning through transcript-based lesson analysis (TBLA). The research was conducted in one of the junior high schools in Garut Regency on science subjects. The learning material studied in this research was about Coulomb’s Law. The learning video was taken from one of the open class activities from a series of lesson study activities. As many as 16 students of grade 9 were included in the study. Through descriptive research methods, researchers revealed learning trajectories and student communication methods while learning through the transcripts made. Learning activities are divided into three main parts, namely introduction, core activities, and closing. There are five stages in the core activity, namely literacy activities, critical thinking, collaboration, communication, and creativity. The results of the analysis show that in the preliminary activity, communication is dominated by the teacher. The dialogue that appears is just a minimalistic dialogue. In core activities, student communication had started to dominate, especially at the collaboration and communication stages. The use of interactive simulation media at the collaboration stage improved the communication between students. The creativity stage was mostly dominated by the teacher, until the closing activity, and less by student communication. The lag time between teacher questions and student answers is the key to student responses. When the pause is given too quickly, there was no communication from students at almost all stages.

Published: April 2024

The global crisis due to COVID-19 demanded changes in people’s behavior to adapt to the pandemic. One factor that determined behaviors was literacy skills, especially in the health sector. A study related to the COVID-19 pandemic was carried out on high school students to assess students’ health literacy and determine related factors. Data collection was carried out from December 2021 to February 2022 by dividing urban areas, developing districts, and remote regions. The Health Literacy Questionnaire (HLQ) was adapted to suit the conditions of the COVID-19 pandemic. The data was interpreted as descriptive-narrative. Differences in literacy ability and the relationship with influencing factors were analyzed using ordinal regression and SEM-AMOS analysis. Limited health literacy was found in students from remote areas. A significant relationship was found between health literacy and class interest based on the ordinal regression test results. In contrast, health literacy was not related to gender, grade level, infected experience, and domicile. It was found that the ability to navigate health system information had a significant effect on students’ understanding of health literacy. Health literacy, which was low and unequal, is expected to improve strategic and sustainable education programs through science learning and physical health.

Effects of Multiple Representation in Student's Conceptual Understanding and Metacognitive Awareness in Mechanics
Authors: Orillo Mark Joseph F. , Mistades Voltaire M.
Published: April 2024

Using a mixed-method design, the study investigated the effect of the use of multiple representations on 207 (106 male and 101 female) Grade 11 students’ conceptual understanding and metacognitive awareness in learning concepts in physics (mechanics). There were five multiple representations (MRs) used in this study namely: (a) drawing/sketch, (b) free-body diagram/FBD, (c) description, (d) mathematical equation, and (e) concept map (Know - Want to know - Learn). These MRs were embedded in the teacher’s lesson plan as a strategy for teaching and learning selected topics in Mechanics. All these MRs were used by the teacher to discuss each lesson, and by the students to understand and do the tasks given to them. The conceptual understanding of the students was measured by obtaining the mean scores from the formative test scores in the form of a 10-item quiz for the following topics - Kinematics, Laws of Motion, and Universal Law of Gravitation. The students’ metacognitive awareness was measured using the 52-item metacognitive awareness inventory (MAI) questionnaire, given before and after the implementation of the teaching-learning intervention. Students’ perceptions on the use of MRs were also gathered in the form of short responses to a 5-item questionnaire. Their responses to these questions were used to elaborate and explain the results in the subcategories of the MAI. Mean scores in the formative tests revealed that students obtained passing grades in all three quizzes. Results also showed that there was an increasing trend in the students’ mean scores from Quiz 1 to Quiz 3. Paired t-test also showed that the increase in the students’ scores moving from Quiz 1, Quiz 2, to Quiz 3 were significant at p < 0.05. The results of the Metacognitive Awareness Inventory (MAI) questionnaire revealed that a significant difference was observed, when comparing the students’ profile scores before and after the implementation of the teaching-learning intervention. The use of multiple representations (MRs) made the students more aware of how they think about learn the physics concepts.

The 21st-century competencies are needed as provisions for college graduates to face the era of society 5.0. These competencies include creative thinking skills, critical thinking, collaboration, and communication. The research aims to illustrate the influence of discovery learning on students’ collaboration skills during real laboratory activities. Discovery learning was chosen because the implementation of practicum activities was carried out in a real laboratory because it requires all the students to play an active role and be able to collaborate in carrying out practicum activities. This type of study uses one pretest-posttest design group. The subject of this study was 30 first-year students from two different classes who took the Basic Physics Practicum II course at the Department of Physics Education, UIN Sunan Gunung Djati Bandung. The implementation of practicum activities is carried out offline so that cooperation and collaboration between groups can be seen. Aspects of the indicator include positive dependence between members, individual responsibilities, group cooperation, and face-to-face interaction. Research data was processed statiscally using the help of SPSS software version 25. Analysis of research results showed that student collaboration skills were complete and appropriate in all indicators. Based on the analysis, an average N-Gain score of 53.2% was obtained with the category being in the criteria for improving collaboration skills.

The pre-research data of mathematics prospective teachers in one of the universities in Bandung showed that the deductive reasoning ability in complex analysis was still not at good level. Beside the cognitive aspect, the affective aspect could be considered too in doing learning process, such as mathematical resilience. This study aims to analyze and identify the correlation between deductive reasoning and mathematical resilience in complex analysis. The research was conducted in one of the mathematics education departments of a university in Bandung. Correlation was the method used in this study. Mathematics prospective teachers were the sample of this research. This study concluded that mathematical deductive reasoning of prospective teachers was on a moderate level, the mathematical resilience of prospective teachers was on the positive category, and there was a significant correlation between deductive reasoning and the mathematical resilience of prospective teachers on a moderate level.

Analysis of Students' Combinatorial Thinking Model in Solving Combinatorics Problems
Authors: Desfitri Rita
Published: April 2024

The purpose of this study was to analyze students’ combinatorial thinking in solving combinatorics problems. This study was organized into two related areas. The first focused on whether students applied combinatorial thinking in Lockwoods’ model, and the second emphasized on students’ ability in solving the given combinatorics problems. This research method used was a qualitative descriptive method. Participants of this study were students majoring mathematics education at Bung Hatta University who took combinatorics courses. Five combinatorics problems were given to the students and then analyzed. The result showed that based on Lockwoods’ model, the aspect of combinatorial thinking that was more widely applied in solving combinatorics problems was the counting process. However, most students who were able to solve problems quite well, and tended to solve problems with steps from formulating, followed by the process of counting to reach a set outcome. Whereas students who did the counting process stage without formulating problems into mathematics expressions, generally checked a set of outcomes by trial and errors. It can also be noted that in general, f/or any problem given, the percentage of students who faced difficulties when formulating problems into mathematical expressions or on the counting process was more that 50%, and the number of students who reached the correct set of outcomes was relatively low.

During the COVID-19 pandemic, it became a challenge for the world of education, all exposure to the implementation of learning was carried out online, however, adjusting the learning process required the readiness of students and teachers in the field of technological literacy. The purpose of writing this paper is: to analyse the ability of mathematical connections between students who carry out GeoGebra-assisted brain-based learning and conventional learning, viewed by gender. The research method used was a quasi-experimental design with a non-equivalent control group. The sample consisted of an experimental class and a control class which were not selected randomly but were selected homogeneously. The implementation was carried out at one of the state middle schools in Bandung, Indonesia. Class VIII-C consists of 30 students as an experimental class carrying out GeoGebra-assisted brain-based learning and class VIII-F consists of 28 students as a conventional class. The instrument used is a mathematical connection ability test. Data analysis using two-way ANOVA. Research results: There is a difference in the achievement of increasing the ability of mathematical connections between students in the experimental class and the conventional class. There is no difference in the achievement of increasing the ability to relate mathematics based on gender (male, female). The brain-based learning approach with the help of GeoGebra facilitates the process of construction, interaction, reflection, and easy-to-understand material, so as to improve students’ mathematical connection abilities.

The purpose of this study was to determine the hypothetical learning trajectory through a problem-based learning model to class VIII junior high school students. Learning mathematics requires a meaningful process and that process cannot be obtained in a relatively short time because it requires good preparation in conveying mathematical concepts to students. The preparation is designed according to the characteristics of students so that the delivery of the material goes well as expected. The preparation referred to in this case is to design a good hypothetical learning trajectory (HLT) according to the needs and subject matter. Hypothetical learning trajectory (HLT) is a temporary hypothesis about students’ activities in the learning process on certain materials. This study uses a design research method with stages referring to Plomp (2013) which consists of three phases including (1) preliminary research; (2) development or prototyping phase; and (3) assessment phase. However, in this research, it is only in the first phase, namely preliminary research. In designing the HLT, it is based on a problem-based learning model which has five stages in each process. The instrument used in this study was a teacher and student interview sheet. The results obtained are the HLT design on linear equation material that is adjusted to the stages in the problem-based learning model. The results obtained from this study can be used as an initial reference for mathematics teachers in designing learning material for linear equations that are in accordance with the real context of students.
