Low learning results, learning motivation, and student confidence are frequently encountered when teaching mathematics in junior high school. To address these issues, it is vital to use learning methods that are appropriate for the student's qualities. The purpose of this study is to investigate and compare the impact of different learning strategies, such as video modelling examples, worked-examples, and practice problems, on students' self-efficacy, motivation, and learning outcomes in the cognitive parts of mathematics teaching. This study used a quantitative methodology and a quasi-experimental design. The study involved eighth-grade pupils from a junior high school in Serang City, who were divided into three classes and given different learning techniques. A learning outcomes exam, a self-efficacy questionnaire, and a motivation survey were used to collect data. To identify significant differences between groups, the obtained data were evaluated using a t-test, one-way ANOVA, and a post hoc Tukey HSD test. The study found that the three strategies had a substantial impact on self-efficacy, motivation, and learning results in the cognitive domain. The practice problem method is more effective at boosting self-efficacy, the video modelling example at raising learning motivation, and the worked example at enhancing learning results in cognitive areas. These findings emphasize the necessity of selecting instructional approaches that are consistent with the targeted learning objectives. Future research should look into the effectiveness of these methods across different topic areas, grade levels, or in combination with other pedagogical approaches to acquire a more complete knowledge of their effects.

The Contextual Teaching and Learning (CTL) approach emphasizes the interconnectedness between academic knowledge and real-life contexts so that learners can build meaningful understanding through authentic experiences. Although many studies on CTL were conducted in Indonesia, the results are still scattered and have not been comprehensively synthesized. Therefore, this study aims to conduct a Systematic Literature Review and meta-analysis to assess the effectiveness of CTL in improving student learning, motivation, communication, and collaboration outcomes in Indonesia. This study uses the Systematic Literature Review (SLR) approach with reference to the PRISMA 2020 guidelines. Articles published between 2013–2025 were searched from Google Scholar, Garuda, Scopus, and DOAJ databases using the keywords "Contextual Teaching and Learning," "effectiveness," "learning outcomes," "motivation," "communication," and "collaboration." Of the 187 articles identified, 19 met the inclusion criteria. The analysis was carried out descriptively, thematically, and quantitatively with a random-effects meta-analysis model. The results of the meta-analysis showed a large and statistically significant combined effect size (SMD = –0.781; 95% CI [–0.938, –0.625]; p < 0.001) with a moderate–high level of heterogeneity (I² = 71.85%). CTL has been proven to improve learning outcomes, intrinsic motivation, and collaborative abilities of students. In addition, the trend of implementing CTL in digital learning and blended learning is increasing in line with the Technological Pedagogical Content Knowledge (TPACK) framework. CTL has proven to be effective at various levels and fields of study in Indonesia. This approach strengthens the theory of constructivism and Self-Determination Theory, and supports the Freedom of Learning policy in shaping 21st-century skills such as critical thinking, communication, and collaboration. Further research is suggested to conduct a cross-border meta-analysis and examine the digital adaptation of CTL in the context of new learning.

This study aimed to examine the effect of the worked-example strategy on students’ learning outcomes in complex mathematics across three time points (pre-test, post-test, delayed-test), and to analyze whether this effect differed based on students’ gender and initial ability levels. A quantitative one-group within-subjects quasi-experimental design was used with 31 eighth-grade students from SMPN 1 Pulosari. Data were collected through validated and reliable test instruments and analyzed using Rasch modeling and inferential statistics. Results showed that the strategy significantly improved learning outcomes (p<0.05), particularly from pre-test to post-test. Although delayed-test scores slightly declined, performance remained high. Moreover, initial differences based on ability levels were observed in the pre-test but they were no longer significant (p>0.05) in the post-test and delayed-test results, suggesting that the strategy helped lower-ability students catch up, reducing learning gaps. Additionally, the study found no significant differences in learning outcomes based on gender (p > 0.05), nor any interaction between gender or ability level and the effectiveness of the worked-example strategy (p>0.05). This study demonstrates the worked example strategy’s effectiveness across time, abilities, and genders in reducing cognitive load and strengthening students’ conceptual understanding. Future studies may compare types, involve varied levels, and use more rigorous designs.

Background: The growing emphasis on higher-order thinking skills has positioned case-based learning (CBL) as a prominent pedagogical approach in contemporary education. Although prior studies highlight its potential to enhance critical thinking, research trends and thematic focus particularly involving preservice teachers remain insufficiently synthesized. Aims: This study aims to identify research trends, bibliometric characteristics, and gaps related to the effectiveness of CBL in improving critical thinking skills, with a specific focus on preservice teachers. The scope includes Scopus-indexed publications from 2015 to 2025. The use of Scopus is considered by taking into account several factors, including quality assurance standards (peer-reviewed publications), reputation and credibility indicators (Scimago Journal Rank/SJR), and its broad multidisciplinary coverage. However, certain limitations remain, such as publication bias related to language and geographical representation, the presence of grey literature, and bias associated with publication types. Methods: A Systematic Literature Review (SLR) combined with bibliometric analysis was conducted. Articles were selected based on predefined inclusion criteria and analyzed by country, subject area, journal quartile, SJR, and H-index. Keyword co-occurrence mapping was performed using VOSviewer. Results: A total of 86 articles met the inclusion criteria, predominantly published in Q1 and Q2 journals within the Social Sciences domain. Bibliometric visualization shows that CBL and critical thinking are widely explored topics; however, studies focusing on preservice teachers and their relationship with decision making (CBL and critical thinking) remain limited. Conclusion: The findings indicate strong scholarly interest in CBL while revealing a clear research gap concerning preservice teachers populations. Future research should prioritize the development of standardized instruments and expand empirical investigations to strengthen evidence-based practices in teacher education.

The Kurikulum Merdeka policy has been implemented extensively in Indonesia since 2022, with one of its focuses being the integration of culture in teaching and learning. Several studies have been conducted on the integration of ethnosciences in science education. However, so far, there have been very few studies that attempt to review the results of the analysis of these articles. Therefore, this study aims to analyze a number of articles related to research on the topic of ethnosciences in science education as an implementation of the Kurikulum Merdeka policy, in order to classify them based on predetermined categories. This study utilizes the systematic literature review (SLR) method, which includes the stages of data search and article collection, article screening, assessment of the quality and suitability of scientific articles, and analysis and data classification. Based on these stages, six scientific articles were obtained, published in six SINTA-accredited journals with a focus on education and published between 2022 and 2023. The results of the quality assessment indicate that four out of the six articles meet the criteria for suitability. Thus, these articles can be considered as sources of information related to research on the topic of ethnosciences in science education as an implementation of the Kurikulum Merdeka policy. The classification has been conducted based on Indonesian culture integrated into science education, educational levels, subjects, and forms of integration of ethnosciences in science education.

Mastery of arithmetic operations is fundamental for students pursuing science education, as these skills are essential in solving complex problems in physics, chemistry, and biology. However, gaps in students' arithmetic proficiency can hinder their academic and professional development. This study aims to examine the arithmetic skills of pre-service science teachers in solving mathematical problems across six domains: addition, subtraction, multiplication, division, exponentiation, and mixed operations. A total of 37 short-answer questions were administered, and the results were analyzed by domain. The findings indicate that students demonstrate proficiency in basic operations involving whole numbers, particularly in addition and subtraction. However, challenges persist in the areas of fractions, decimals, and mixed operations, where accuracy rates were notably lower. These gaps in understanding may affect students' ability to apply mathematical concepts in their science courses and future teaching roles. The study's limitations include a focus on quantitative results without exploring the cognitive processes behind student errors. Future research should investigate intervention strategies to address these weaknesses, potentially through targeted instructional approaches or the use of technology to enhance learning outcomes

The integration of computational thinking (CT) has become increasingly essential in mathematics education, particularly in topics that require spatial reasoning and structured problem solving, such as flat-surfaced solid geometry. This study aims to synthesize empirical evidence on students’ computational thinking abilities within this specific mathematical context through a Systematic Literature Review (SLR). Using a descriptive qualitative approach, this review analyzed seven peer-reviewed articles published between 2020 and 2025 in nationally accredited journals indexed at SINTA levels 1–5. The literature search was conducted using Google Scholar and Publish or Perish, guided by predefined inclusion and exclusion criteria, and the study selection process followed PRISMA guidelines. The findings reveal that students’ computational thinking abilities are generally at low to moderate levels and unevenly developed across indicators, with abstraction and decomposition more prominent than pattern recognition and algorithmic thinking. Instructional designs incorporating visualization, contextualization, and structured problem engagement effectively supported CT development, whereas unplugged and manipulative-based activities proved beneficial at the elementary level. However, most studies emphasize outcome-based assessments and provide limited insight into students’ cognitive processes during problem solving. These findings highlight the need for theoretically grounded instructional designs and process-oriented assessment frameworks to support a more integrated and sustainable development of computational thinking in geometry learning.
