Lifetime and Current Predictors of Non-Suicidal Self-Injury Among College Students
Authors: SULAK AKYÜZ Bilge , BHAT Christine Suniti
Published: January 2024

Informed by previous research on non-suicidal self-injury, researchers in the current study sought to understand further the relationships between non-suicidal self-injury, self-esteem, anxiety, and biological sex among college students. Further, the researchers were interested in both current non-suicidal self-injury engagement and lifetime non-suicidal self-injury engagement, which could provide information on prevalence before and after commencing college. In order to examine the predictive relationships between lifetime non-suicidal self-injury engagement, current non-suicidal self-injury engagement, self-esteem, anxiety, and biological sex, participants completed several instruments assessing aforementioned variables. Results yielded that non-suicidal self-injury engagement rate was higher before commencing college. It was further found that while trait anxiety was a significant predictor for current non-suicidal self-injury occurrence, self-esteem was a significant predictor of lifetime non-suicidal self-injury occurrence. Concerning non-suicidal self-injury functions, affect regulation was the leading reason to engage in non-suicidal self-injury followed by self-punishment and anti-dissociation/marking distress.

Published: January 2024

Various international and national tests are applied to assess curricula across the world. About 250.000 students’ knowledge and skills are tested via Trends in International Mathematics and Science Study (TIMSS). Many international and national comparisons are made with the test results. However, to be able to compare the test results of such a big crowd of people, the test results must not differ because of any other variable but achievement; in short, they must represent the same results of measurement. In the light of this information, the purpose of the study is to examine the measurement invariance of the model of the science affective factors of the eighth graders participated in TIMSS 2015 Turkey which is constructed via structural equation modeling, among Nomenclature of Territorial Units for Statistics – Level 1 regions and genders in Turkey, through multi-group confirmatory factor analysis. The sample of this research consists of 5344 students and the analyses was made by using SPSS 23.0 and AMOS 23.0 softwares. As a result of this study, the model met strict invariance for genders and scalar invariance for regions

Authors: YILDIZ Avni , KARADUMAN Engin
Published: January 2024

Developing entrepreneurial skills at all educational levels, but especially in the early years of education is critical for growing individuals that are able to adapt to a world that is rapidly changing and for the development of society at large. In order to stimulate students' entrepreneurial endeavors, educators, policymakers, and scholars need to understand the characteristics of their entrepreneurial behavior. Thus, the purpose of this study is to examine a number of variables about the relative characteristics of entrepreneurship such as leadership and leadership responsibility, personal gain, need for achievement, and self-confidence among gifted students and those who are not identified as gifted in 5th grade. The present study employs a descriptive research model in order to reach generalizations by comparing some variables and entrepreneurship between gifted students and 5th-grade students who are not identified as gifted. Additionally, the causal comparison approach was utilized, by examining the research question separately by gender, school type, participation in science activities outside of school, the choice of a career related to mathematics and the perception of competence in mathematics. In terms of the scale, the results of the research show that there is no significant difference between gifted students and students without a diagnosis of giftedness. However, the average for gifted students is higher than the average for non-gifted students.

Published: January 2024

Environment problems and the effects of climate crisis give rise to different consequences and affect the lives of people. Therefore, educating students with awareness and sensitiveness about this subject at an early age has become obligatory. In other words, the environmental education instructed at schools is always supposed to be up to date in this context. In this research, the historical background of the content of the Environment Education and Climate Change Lesson's curriculum is investigated which is instructed to secondary school students as a selective course in Türkiye. The instruction durations at schools, content, learning fields, distribution of the subjects and the number of the outcomes of environmental education's curriculum are examined progressively. In this research, the weekly schedule of the lesson and document analysis of the curriculum are performed, and the results are presented. Consequently, it is understood that there was not any independent lesson named as environmental education in Türkiye until the 1990s; the instructional statute of the lesson from the beginning of primary schools differentiated as selective or compulsory in the meanwhile; the names of independent lessons about environmental education are changed in time; the instructional levels of the grades are increased in number with the latest updates; the climate crisis and disaster trainings are highlighted as independent subjects, and the content is developed mainly for practical applications rather than transfer of academic knowledge.

Authors: GÜMÜŞ Özge , BAŞÖZ Tutku
Published: January 2024

Recent trends in the field of second language learning motivation have led to a proliferation of studies that scrutinize Directed Motivational Currents (DMCs). However, there remains a paucity of evidence on the individual difference variables that induce DMCs. In particular, research to date has not yet determined the role of ideal L2 self and mindset in explaining variations in the DMC disposition. This quantitative study aims to fill these gaps in the literature by exploring the role of ideal L2 self and growth mindset in explaining EFL Learners’ DMCs. The current study was conducted with a total of 176 preparatory class students enrolled in the department of English Language and Literature or English Language Teaching at various state universities in Turkey. The data were gathered using a composite survey instrument that includes the DMC Disposition Scale, the Mindset Instrument, and Ideal L2 Self Scale. The findings of the multiple linear regression analysis indicated that growth mindset explained 32% of the variance in EFL learners’ DMCs whereas ideal L2 self contributed to the prediction of DMCs, explaining 24% of the variance in participants’ DMC disposition. The results offer new insights into how teachers could exploit these motivational surges to promote learning in EFL settings.

opinions were examined; it is understood that participants often use social
media to follow the agenda / people. When the codes are examined, it is seen
that the participants mostly talk about communication / interaction and educational
use while explaining the reasons for using social media. It is understood that
the participants prefer not to use social media mostly because of lack of
technical knowledge and skills. Afterwards, it is seen that the reasons for not
making any contribution / unnecessary, health problems, not attracting
attention and not being widespread / not being used in the past were among the
reasons for not using social media.
An Analysis of Turkish Pre-service Preschool Teachers’ Self-image on a Science Education Course
Authors: ATASOY Volkan , AHİ Berat
Published: January 2024

The purpose of the current study is to investigate the changes of self-image occurring in pre-service preschool teachers during a course of science education. The study employed the phenomenological research method within the framework of a qualitative perspective. A total number of 75 pre-service preschool teachers participated in the study on a voluntary basis and they were asked to draw a picture to reflect their state during the science education course and to explain it. The findings derived from these drawings were found to be subsumed under four categories: cognitive, implementation, affective and social. It was also found that the pre-service preschool teachers had difficulties in understanding science while emphasized a teacher-centered approach to its teaching. Moreover, inconsistent feelings and attitudes towards the subject were observed and social interaction was not depicted very much. In the light of the findings, it is suggested that preschool teacher education programs should be revised to provide effective science education. It is thought that teacher educators and mentors play an important role in pre-service preschool teachers acquiring adequate knowledge and skills and developing positive attitudes

Authors: ÖZER Mahmut
Published: January 2024

The importance of vocational education and training (VET) becomes more visible during coronavirus pandemic in Turkey. With increased capacity in production VET has become one of main supplier of society needs in these days. In this study, developments in production via VET within the scope of coronavirus measures are briefly reviewed. Additionally, improvement areas and steps that need to be taken for strengthening VET are discussed. In pandemic days, cleaning materials, medical masks, and disposable materials are main products, which are experiencing difficulties in procuring. With the support of Ministry of National Education, 10 million masks are producing in VET high schools monthly. Cleaning material needs of all schools around Turkey can meet with the productions of VET high schools. Face protection shields, disposable materials, and face masks with N95 standard are produced via R&D studies in VET and they are shared with healthcare professionals. This study shows that VET in Turkey can respond to needs of society quickly in pandemic days with developments in VET in recent two years after the announcement of 2023 Educational Vision. A strengthened VET system with mentioned points in the study can play a major role in meeting the society needs in crisis period.

Authors: UZUN Ayşenur , KILIÇKAYA Ferit
Published: January 2024

One of the most important dynamics of the educational setting all over the world is examinations, and some of those are English tests. In Turkey, English tests for the students preparing for the high schools were included in the national exams with the Level Determination Exam (SBS) in 2008 for the first time, and Transition Examination from Primary to Secondary Education (TEPSE) replaced them in 2013. The effects of these exams have been investigated; however, to the best knowledge of the author, other principles of language assessment such as validity and reliability have not been investigated based on the analysis of documents. This study, therefore, aimed to investigate content validity of the English tests in TEPSE, which were conducted between 2016 and 2017. Data collection procedure included the analyses of TEPSE English tests, the coursebook, the curriculum of 8th grade and semi-structured interviews held with 21 English language teachers. The analyses of the frequently used items in the coursebook and table of specifications were used to examine the content validity. The results revealed that despite some factors, TEPSE English tests between 2016 and 2017 have content validity based on the alignment between the coursebook and TEPSE English tests.

Authors: Fatikasari Tanty , Nurhasanah Iis , Khumaeni Ali
Published: January 2024

There are numerous green methods for synthesizing silver nanoparticles using plant extracts such as leaves, flowers, stems, and fruit extracts. However, most of those synthesized have weaknesses such as slow reduction and inefficient time. This study used a microwave to accelerate the reduction process of Ag+ ions into Ag0 nanoparticles using an aqueous extract of Citrus sinensis peels. A heating time of 5 minutes produces silver nanoparticles in optimal condition with a color change from yellow to reddish brown. According to UV-Vis, silver nanoparticles at power 100 W and 300 W show peaks at 404 nm and 406 nm. FTIR indicates that phytochemical compounds are involved in the reduction of nanoparticles. XRD shows silver nanoparticles are FCC crystalline. TEM reveals that power 100 W yields an average diameter of 12 nm while 300 W shows a smaller diameter of 5 nm.

Authors: Pytlík Petr
Published: January 2024

Článek představuje výsledky šetření, které proběhlo mezi osobami s mezinárodní ochranou v České republice v letech 2020–2022 a bylo zaměřeno na otázku využívání médií při autonomním učení se češtiny jako cizího jazyka. Hlavním cílem bylo zjistit, nakolik se z pohledu osob s mezinárodní ochranou projevil nástup nových médií v autonomním, ale i řízeném rozvoji řečových dovedností v češtině jako druhém jazyku, a – pokud došlo k zásadním změnám – na které dovednosti je nutno se v integračních jazykových kurzech češtiny nově zaměřit.
Metody – V rámci šetření proběhlo celkem 27 strukturovaných rozhovorů s kvalifikováním odpovědí v dotazníku, které byly posléze interpretovány na základě fenomenologické analýzy.
Výsledky a závěry – Z šetření vyplynulo, že osoby s mezinárodní ochranou jsou dobře obeznámeny s možnostmi využití médií při autonomním učení se češtiny a že za tímto účelem cíleně využívají jak tradiční, tak nová média. Současně bylo možno vysledovat, že jsou si vědomy rozdílů v rozvoji jednotlivých řečových dovedností. Zejména rozvoj produktivních dovedností, tedy mluvení a psaní, očekávají od jazykových integračních kurzů nabízených státem.
Transformative Dynamics of Youth Involvement in the Just Transition Process: The Case of Active Youths in the Region of Western Macedonia, Greece
Authors: Stergiou Konstantinos , Filippidis Kostas , Papoutzis Lazaros , Zourka Stefania
Published: January 2024

Western Macedonia, a region nestled in the northwestern part of Greece, has long been renowned for its rich natural resources, particularly its abundant coal reserves. Τhe imperative to transition away from coal-related industries has brought to light the need for economic diversification. Western Macedonia's heavy dependence on coal mining and energy production has left it vulnerable to the inevitable decline of fossil fuels (Ziouzios, Karlopoulos, Fragkos, Vrontitsi, 2021). To secure its future and ensure the well-being of its residents, the region must identify and develop new economic sectors that align with a sustainable, low-carbon future.  However, as the global shift towards sustainable energy production gains momentum -and as the climate crisis shows its harsh face-, Western Macedonia has found itself facing a myriad of challenges that have constrained the initiation of a Just Transition process in regions that were dependent on lignite (Vatalis, Avlogiaris, Tsalis 2022). The transition seeks to address critical issues, such as staggering unemployment rates, the significant brain drain of the region, and the need to diversify its economy away from coal-dependent industries.
Comparative the effect of distribution transformer coil shape on electromagnetic forces and their distribution using the FEM
Authors: Hameed Kassim Rasheed , Suraiji Ahlam Luaibi , Hanfesh Abduljabbar O.
Published: January 2024

During the normal life of the transformers, they are subjected to different electromagnetic stresses. One of these stresses is the electromagnetic forces resulting from the passage of short-circuit current in the transformer coils due to internal or external faults and may lead to the failure of the transformer when this electromagnetic force exceeds the threshold level. This work deals with the computation and analysis of leakage magnetic flux and electromagnetic forces when the worst-case fault (symmetrical short-circuit current) occurs in distribution transformer (DT) coils using the finite element method (FEM). The three types of DTs that were adopted in this work are similar in capacity and voltage transformation ratio (250 kVA and 11,000/416 V), but they are different in the shape of coils (oval, cylindrical, and rectangular coils).

ANSYS software was used to build two-dimensional models of the three transformers, which were different in coil shapes and in the type of iron core. The objective of this work is to compare the effect of coil shape on the distribution of electromagnetic forces and their value, in order to find out which coil shape is the best to withstand electromagnetic forces when short-circuit current is passed in the coils. The results of the simulation of the finite element models were approximately equivalent to the results of the design calculations that depend on the classical method (the analytical method), but the FEM is more accurate, due to the accuracy of calculating the magnetic flux and its distribution, which cannot be calculated using the classical method. One of the most important contributions of this research is the analysis and calculation of electromagnetic forces for three types of DTs with different coils by applying the same design parameters to all the transformers. The research also contributed to determining the best coil shape by comparing simulation results, and it was found that transformers with cylindrical coils are the best to withstand electromagnetic forces due to the homogeneity of the cylindrical coil structure from all sides.
Personality as technology of self: MBTI and English language learning in South Korea
Authors: Park Joseph Sung-Yul
Published: January 2024

This paper considers how a particular understanding of personality, as manifest in the way discourses about personality types are circulated and employed, may serve as a foundation for rationalizing the logic of human capital and its concomitant inequalities. Focusing on the recent popularity of the Myers-Briggs Type Indicator (MBTI) in South Korea and the way it is adopted in online content offering advice on English language learning, this paper suggests that a conceptualization of personality as simultaneously enduring and inherent, on the one hand, and standardized and technologized, on the other, allows personality testing and personality type to serve as moral technologies of self that conceal the contradictions underlying the promotion of English language learning as a key to developing one’s human capital in neoliberal Korean society.

Published: January 2024

Towards a Poetics and Ethics of Climate ProtectionThe study addresses the urgent need for a comprehensive approach to climate change, emphasising the role of individual responsibility and political action. It advocates for a shift in thinking, where each person acknowledges their responsibility for climate change, which is crucial for developing effective strategies to combat it. The author agrees with the consensus among climate scientists and scientific circles that human activity is the primary cause of global warming. However, argues that a democratic society lacks a single authoritative figure to dictate actions, placing the onus on individuals to act responsibly and ethically. Exploring the ethical dimensions, the text delves into the philosophical and ethical implications of our relationship with the Earth, drawing on Saint Augustine's reflections on time and the nature of the past. It discusses the concept of exploiting the Earth's resources, likening it to enslaving the past, and emphasises the need to treat these resources as partners in our survival rather than mere commodities. The author argues for a sustainable and ethical approach to resource management, advocating for a balance between taking from and giving back to the Earth. The text concludes by discussing the role of technology, ethics, and legislation in reversing climate change. It highlights the need for more excellent knowledge, responsibility, and collective action to understand and mitigate the adverse effects of climate change. János Boros calls for extending Kant's categorical imperative to include the Earth, emphasising the moral obligation to protect and sustain the planet for future generations. Overall, the study is a comprehensive and philosophical exploration of climate change's ethical and practical challenges, advocating for individual responsibility, strong legislative action, and reevaluating our relationship with the Earth.

Influence of Moisture Content on Physical and Mechanical Properties of Chinese Ash Bolts for Anchoring Earthen Sites
Authors: Wang Nan , Yan Feifei , Qiu Qibo , Zou Hongyu , Zhang Jingke , Bai Dongming , Suo Chenyang
Published: January 2024

Chinese ash bolts are extensively utilized for anchoring earthen sites in China, but their physical and mechanical properties are influenced by changes in moisture content during the grout curing process. This study reveals significant effects on compressive strength parallel to the grain and flexural strength, with a comparatively lower influence on tensile strength parallel to the grain. As moisture content increases, the failure mode shifts from fiber fracture to inter-fiber destruction, resulting in a transition from brittleness to elastoplasticity in the bolts’ properties. Additionally, we observed that the diameter of the samples has a less pronounced effect on mechanical strength and modulus compared to moisture content, though it notably enhances resistance to deformation. Scanning electron microscopy images show interlocking textures within the wooden fibers, effectively enhancing the strength and toughness of the bolts. Importantly, this research presents quantitative results: Chinese ash bolts exhibit a natural density range of 0.65 to 0.78 g/cm3 and a saturation moisture content spanning from 93.15 to 114.15 %. Furthermore, in their natural state, these bolts display remarkable tensile strength (126.56 MPa), compressive strength (55.91 MPa), and bending strength (106.34 MPa). This study highlights the critical significance of carefully choosing the most suitable bolt diameters to fortify resistance against deformation. The concrete data provided contribute significantly to improving conservation practices for earthen sites.
Research on Magnetic Memory Detection of Weld Fatigue Damage Based on Two-Dimensional Spectral Entropy
Authors: He Zhenfeng , Zhou Jianting , Liu Dingkun , Liao Leng
Published: January 2024

In light of the intrinsic relationship between weld fatigue damage and the characteristics of magnetic leakage signals, fatigue experiments were conducted on butt welds to analyze the evolution of magnetic leakage signal as fatigue cycles increased. The introduction of two-dimensional spectral entropy allowed for the construction of a fatigue stage division model based on the two-dimensional spectral entropy diagram. The results revealed that distinctions between magnetic leakage signal under loaded and unloaded conditions were solely evident in their magnitude, with consistent curve distribution trends observed across various fatigue cycles. Furthermore, the distribution pattern of magnetic leakage signal displayed significant fluctuations, characterized by a sharp gradient increase following the emergence of fatigue cracks. These distribution characteristics of magnetic leakage signal differed markedly from the magnetic field distribution at other fatigue stages, with a higher growth rate observed as fatigue cycles increased. The two-dimensional spectral entropy spectrum analysis of magnetic leakage signals at different fatigue stages indicated the disorder in the magnetic leakage signal distribution within the high fatigue zone, signifying the expansion of fatigue microcracks. To some extent, two-dimensional spectral entropy can serve as an early warning system for detecting fatigue cracks in welds and achieving early identification of fatigue microcracks.

The Legend of Lola Casanova
Authors: McKee Irwin Robert
Published: January 2024

This article contrasts two stories of nineteenth-century interracial romance, the Mexican borderlands legend of Lola Casanova and the U.S. borderlands novel Ramona. It argues that the Casanova legend suggests Mexican attitudes toward interracial marriage that differ significantly from those understood in recent readings of Ramona by U.S.- based scholars. This disparity draws attention to a blind spot in U.S.-based border studies: its tendency toward an exclusive focus on the U.S. Southwest that utterly disregards a Mexican borderlands perspective. I argue that border studies scholars need to engage more readily in cross-border dialogue.
Queer Chisme
Authors: Gutierrez Lizeth
Published: January 2024

This essay examines chisme as a form of feminist knowledge production. Various scholars have theorized gossip as an oral practice of sharing information to affirm and/ or police membership in social groups. Using Josefina López’s play Real Women Have Curves (1996), this essay queers chisme as an antinormative feminist practice, defining it as a culturally specific homosocial form of bonding that reconfigures emotional security beyond the boundaries of heteronormative kinship structures. I begin by exploring the historical and political processes linked to global capitalism, the feminization of labor, and heteronormative US immigration policies, illustrating how these systems of containment discipline Mexican women to specific heteronormative networks of emotional security. I then articulate chisme as a “slippage” of this imposed discipline by theorizing the ways in which chisme deploys its own performative erotic power within global capitalism, allowing immigrant women to create an alternative definition of emotional security that centers community, fights back against patriarchy, and produces feminist knowledge. In this way Mexican immigrant women’s discourses are not only feminist acts but also political countersites of revolutionary love.
Yearning to Belong, Drawn to Be Mexican
Authors: Estill Adriana , Bebout Lee
Published: January 2024

This essay analyzes two contemporary Hollywood films—Fools Rush In (1997) and McFarland, USA (2015)—to highlight the mainstream imaginary of the relationship between Mexicanness and whiteness. We argue that these fi lms reveal how the existence and persistence of an emotionally impoverished whiteness becomes visible beside, against, and through Mexican affective fullness. We develop the term “white lack” to represent how whiteness, in all its modernity and focus on individual autonomy, is exposed as incomplete and even insufficient once it knows and “feels” the warmth and abundance of Mexicanness. We show that the political logics of white lack reveal a yearning not just for human connection but also for a different social order and relationship to place. Yet even as these fi lms gesture toward moments of interracial harmony and anticapitalist possibilities, they both retain the centrality of the white hegemonic gaze; indeed, Mexican affective fullness must be contained and reabsorbed into the body of whiteness by the end of each film.
Mapping Opposition in the Sonora- Arizona Borderlands
Authors: Rivera Díana Noreen
Published: January 2024

Federico Ronstadt’s Borderman, a memoir written between 1944 and 1954, recounts the businessman’s immigration to Tucson and his life in the Sonora- Arizona borderlands during the late nineteenth and early twentieth centuries. Paradigms of opposition that inform the recovery of early Mexican American memoir and autobiography—centering the life writings of elite, dispossessed Mexican Americans and Hispanic immigrant literature written in Spanish—have discouraged study of Ronstadt’s English-language, seemingly assimilationist memoir. In my critical recovery of Borderman, I argue that it should be read as part of the legacy of oppositional literature written by people of Mexican descent in the United States. I historicize Ronstadt’s writing moment as the decade that culminated in Operation Wetback and introduce images from his archive to support a critical reading of Borderman as oppositional to the anti-Mexican border policies of its era. Building upon Genaro Padilla’s, Tey Diana Rebolledo’s, and Nicolás Kanellos’s discussions of oppositional textual politics, and mobilizing Chicana literary spatial studies, I use the term “cartographic opposition” to evaluate Borderman’s discursive remapping of southern Arizona from associations with the Anglo Southwest to a transfrontera geopolitical and cultural expanse.
Mapping the Burrito Circuit
Authors: Martinez-Cruz Paloma
Published: January 2024

Formed in 2002 in Los Angeles, the Aggrolites contribute to the Chicano reggae and ska revival scene while maintaining fi delity to the Chicano power soundscapes that gained cohesion along the “Burrito Circuit.” This essay defi nes the Burrito Circuit based on interviews, an analysis of three representative Aggrolites songs, and album cover art that reflects the early Chicano movement’s visual representations of cultural affirmation. Featuring bands such as Thee Midniters, the Premiers, Tierra, and Los Lobos, the Burrito Circuit helped develop a nonrepresentational stylistic influence that expands our understanding of Chicano soundscapes beyond the Mexican corrido and Afro-Cuban styles previously associated with cultural reclamation. As national popular music catalogs remain organized along a grid of R&B (“black”) and pop (“white”) music, Chicano identity markers within these racialized categories have largely gone unacknowledged. By examining the Aggrolites’ brand of Chicano soul, funk, and garage rock–infl ected reggae, as well as their visual profi le that hails working-class Chicano experience, we can discern how the Burrito Circuit’s sound and sights that began on Los Angeles’s Eastside continue to be sensually available and politically relevant to audiences as an expression of cultural audibility and spatial entitlement.

Agricultural extension has long been the subject of scholarly critiques for its hierarchical approach to knowledge transfer and its complicity in promoting agricultural intensification and farm sector consolidation. Here, however, we suggest that there are already-existing examples of different kinds of agricultural extension practices, ones that challenge the capitalist—understood here as synonymous with racial capitalist—paradigm that dominates in California’s agricultural landscapes and elsewhere. We discuss one such example, providing a case study of Diana’s efforts to support Spanish-speaking, small-scale, Latine farmers in California. Drawing from feminist political economic theory, we argue that extension is a site of heterogeneity, where existing power asymmetries are both maintained and transformed. Diana’s efforts to transform such power asymmetries illustrate the labor that some extensionists mobilize to support small-scale Latine farmers and other farmers of color in the context of U.S. agri-capitalism. We highlight 4 ways in which Diana’s labor disrupts extension norms, including (1) filling gaps in state programs with invisible labor, (2) building mutual trust through social relationships beyond work, (3) blurring distinctions between extension work and farm work, and (4) broadening definitions of “farmers” beyond business ownership and land tenure. In doing so, we advocate for a critical understanding of heterogeneity among extension practices, as extensionists both contribute to and challenge racial-economic inequalities in the agri-food system. With this approach, we hope to identify and better understand how contestations of dominant power arrangements can and do occur in extension contexts in the hopes of supporting these efforts.

This study aims to explore the concepts of ecology and biodiversity, the value of environmental preservation in gunungan wayang kulit purwa, and its correlation to science learning or environmental education in a science subject at the junior high school level to increase environmental awareness. This research employed a qualitative descriptive approach. This research included ethnographic research associated with symbolic interpretation in anthropology. The informants of this study were a puppeteer (dalang), a javanology expert, a gunungan wayang kulit purwa creator, and a biodiversity expert chosen by purposive sampling. Data were collected through semi-structured interviews, literature reviews, and content analysis. Data triangulation was applied to ensure the data validity. The data were analyzed using a spiral analysis model, including managing, reading, marking, describing, classifying, interpreting, and visualizing data continuously. The study results show that the gunungan wayang kulit purwa contains the conservation value and concept of ecology and biodiversity. This concept has a correlation with the material on ecology and biodiversity in the independent curriculum in a science subject at schools. The ecological concept includes biotic and abiotic components, symbiosis, pollinators and predators, food chains, food webs, competition, and the value of environmental preservation. The findings in the form of a link between ecological concepts and biodiversity in the gunungan wayang kulit purwa have implications for the potential use of gunungan wayang kulit purwa as a learning resource for science education in schools or environmental education to increase environmental awareness of the young generation.

The starting point of this research is the absence of understanding of students’ conceptions of the human movement system material, as well as students’ unformed creativity. This study aims to analyze the effect of the STEM-approach PjBL model on students’ conceptual understanding and creativity. This research was quantitative research with a quasi-experimental method with a post-test-only control design type. The sampling used a purposive sampling technique. The instruments used were concept comprehension tests, syntax implementation observation sheets, and creativity questionnaire sheets. The paired sample t-test was used to analyze the data. Based on data analysis, the average post-test results for the experimental and control classes are 83.44 and 79.14, respectively. The data analysis of the student creativity questionnaire results suggest that 19 students are quite creative. The paired t-test result for students’ concept understanding is 0.002, indicating that the research hypothesis is accepted, while the result for creativity is 0.64. With moderate criteria, the PjBL model with the STEM approach effects students’ conceptual understanding and creativity.

This study examined students’ attitudes, study habits, and academic performance in science using self-learning modules. This type of research is a descriptive-correlational design utilizing a standardized survey questionnaire. The research subjects were 174 secondary students in a public school. Data analysis used descriptive techniques, Pearson’s correlation coefficient, and multiple regression analysis. Findings revealed that students have a positive attitude toward science and have fair study habits. Students are very satisfactory in time management, concentration, goal setting preparation and follow-up, comprehension, and use of resources. Hence, students positively perceive that Science teachers in distance learning using the SLMs make science enjoyable and present material. This study concluded that using the self-learning modules, students have positive attitudes toward science, very satisfactory study habits, and most of the students have satisfactory academic performance. No correlation was found between students’ academic performance and attitudes toward science using self-learning modules and between academic performance and study habits in science. However, a positive correlation existed between students’ attitudes toward science and study habits using self-learning modules. This study will have important implications for education in the new normal, including improving student engagement and motivation by understanding the relationship between attitudes, study habits and academic performance will help educators to design self-learning modules that support students in developing positive attitudes, study habits, leading to improved engagement and motivation.

This research aims to investigate the potential impact of STEM-based scientific learning on the critical and creative thinking skills of students at Universitas Pendidikan Ganesha in Indonesia. To achieve this goal, we conducted a quasi-experimental research design to collect data. We provided students with hands-on experiences in conducting scientific experiments to solve real-world problems related to energy and air. Data regarding students’ critical thinking skills were gathered through tests, while data about creative thinking skills were obtained by observing students’ performance in mind-mapping exercises. The collected data underwent thorough statistical analysis, including descriptive and inferential techniques. The results of this research show that students taught using the STEM-based scientific learning model outperform those taught using the conventional model (lecturing). Furthermore, inferential statistical research shows that using the STEM-based scientific learning model predicts students’ critical and creative thinking skills considerably. These results imply that using the STEM-based scientific learning model can help students improve their critical and creative thinking skills. This shows the potential to add to the body of literature on the influence of STEM-based scientific learning in developing students’ critical and creative thinking skills. Further, this study can serve as a basic reference for future studies aimed at investigating the influence of STEM-based scientific education on students from various educational backgrounds and cultural settings.
