Abstract

The purpose of this study is to strengthen the mental model of prospective elementary school teacher candidates by using the MIKiR (mengalami, interaksi, komunikasi, internalisasi, and refleksi) method, which is directed towards conceptual growth and is based on the MIKiR framework (CDOI Model). The research was carried out utilizing a pre-experimental approach with a pretest-posttest design in one group for this study. The research was carried out on pre-service primary teachers at the Universitas Riau, in Indonesia. The instrument used to collect data was a heat transfer conceptual understanding test (HTCU Test), which consisted of three sections of the question, each of which had previously been verified and evaluated to ensure that the participants were eligible. Using the MIKiR approach (experiencing, interaction, communication, and reflection), this study found that implementing the CDOI model of conceptual development-oriented instruction had a high level of success in enabling the creation of mental models. Furthermore, it can aid in the conceptualization and development of the concept of heat transfer and the formulation and overall knowledge of the concept.

Abstract

Mathematics is a universal science that will continue to develop along with the times, a science that is obtained carefully, clearly, and accurately. Learning and understanding math is difficult, complicated and scary because it requires students to think logically, carefully, diligently, systematically, and must have learning motivation. Learning motivation is a description that is often used to explain the success of students' learning tasks, the time and effort they devote to them, so that the desired learning goals are achieved. The higher the child's motivation, the higher the learning outcomes obtained by students. To increase students' motivation and learning outcomes in this study using the Student Teams Achievement Division (STAD) cooperative type. The purpose of this study was to determine the learning motivation and mathematics learning outcomes of students in classes that used Student Teams Achievement Division (STAD) cooperative type. The population in this study was the learning motivation and mathematics learning outcomes of grade XI students of MA Negri 1 Indramayu. The sample was selected randomly. The instruments used were a test of description questions and observation sheets of student motivation. The results of data processing obtained the average in cycle 1 for learning outcomes is 78.75 and the average motivation in cycle 1 is 2.86 with a sufficient category of 19 students and a less category of 7 students. The results of data processing in cycle 2 obtained an average for learning outcomes of 80.00 and an average motivation in cycle 2 of 3.36 with a sufficient category of 23 students and a good category of 3 students. And the results of data processing in cycle 3 obtained an average for learning outcomes of 86.92 and an average motivation in cycle 3 of 3.86 with a good category of 25 students and a very good category of 1 student. So it can be concluded that cooperative learning type Student Teams Achievement Division (STAD) can increase students' motivation and math learning outcomes. For further research, other methods can be developed to improve student learning outcomes.

Abstract

As an international benchmark, the Programme for International Student Assessment (PISA) 2022 evaluates the educational performance of 15-year-old students across various countries. It has been observed that the average mathematics score globally declined in 2022. Understanding the responses of mathematics teachers, as practitioners, to the PISA 2022 results is crucial for evaluating the reasons behind this decline in mathematics scores. This research aims to explore and understand the perspectives of Indonesian mathematics teachers on the factors contributing to the low PISA 2022 mathematics scores. This study employs a qualitative approach, with participants being randomly selected and includes interviews with 36 mathematics teachers in Indonesia. According to the statements provided by teachers, the decline in mathematics scores in the 2022 PISA, relative to the years 2018 and 2015, can be attributed to six primary factors: pandemic-related issues, curriculum, individual factors, resource limitations, student factors, and parental involvement. Subsequently, mathematics teachers provided several recommendations for the government, schools, and parents that might enhance student mathematics achievement. These recommendations include conducting more training, improving ICT facilities in schools, and strengthening parental knowledge about the importance of parental support. The findings of this study offer various recommendations that could be implemented by the government, schools, and mathematics teachers to improve student mathematical achievement and potentially increase PISA scores in 2025.

Abstract

Ethnochemistry is the study of chemical practices by specific cultural groups that are used for activities following the ideology of the community, including the Banjarese community. Banjar ethnochemistry can be integrated into science learning, especially for Indonesia’s senior high school chemistry learning context. This study aims to analyze the results of exploring the local wisdom of the Banjarese community, which is included in ethnochemistry, and to take an inventory of Banjar ethnochemical knowledge as a source of Indonesia senior high school chemistry learning. The study uses an exploratory qualitative approach with ethnographic methods. The subjects in this research are community leaders and academics who understand Banjar ethnochemistry. Data collection techniques used interviews, observation, and documentation. The results of the Banjar ethnochemical exploration include Banjar soup, sasirangan, basungu, rub ash, batimung, sepat dry fish, diamond, tanggui, tapai Gambut, laduman, kelakai, ironwood, ironwood hair oil, fish pentol, selangat shredded fish, Mangurak wells, mandai, and lahang ice. An inventory of Banjar ethnochemical knowledge that can be used as a source for Indonesia senior high school chemistry learning consists of acids and bases, chemistry and its scope, alkane derivatives, macromolecules, elemental chemistry, and colligative properties of solutions.

Abstract

Mathematics anxiety is a persistent psychological barrier that negatively affects students’ learning processes and academic performance in mathematics. While previous studies have examined psychological and cognitive predictors of mathematics anxiety, limited research has explored their interaction using an integrative moderated mediation framework. Using a cross-sectional design, data were collected from 145 Grade VIII students at an Indonesian public junior high school. The relationships among variables were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The results indicate that self-efficacy significantly reduces mathematics anxiety and positively predicts mathematical reasoning. Mathematical reasoning also negatively predicts mathematics anxiety and partially mediates the relationship between self-efficacy and anxiety. In addition, self-efficacy moderates the relationship between reasoning and anxiety (β = 0.149), indicating that reasoning skills are more effective at reducing anxiety when students have greater confidence in their mathematical abilities. Mediation analysis further reveals that mathematical reasoning partially mediates the relationship between self-efficacy and mathematics anxiety. These findings highlight the critical interplay between psychological and cognitive factors in mitigating mathematics anxiety, suggesting that reducing anxiety requires a dual-track approach that strengthens students’ mathematical reasoning while simultaneously fostering self-efficacy through confidence-supportive instructional practices such as problem-based and case-based learning.
