Abstract

Interest is an essential element in designing chemistry learning. Teaching students based on interest trains sensitivity and as a reinforcement of chemical content, including triggering students' thinking processes through relevant teaching materials. However, the development of teaching materials focused on the interest approach is still limited, especially in chemistry education in higher education. The research method uses the ADDIE development model (analyse, design, develop, implement, evaluate), with data collection techniques using questionnaires, observation, and documentation, including product feasibility criteria (valid, practical, and effective). The data analysis technique uses a quantitative approach, especially in the aspects of validity to product effectiveness. The results show that the products obtained through the development model and show that the product is declared feasible, with a high validity of 88.80%, practical implementation of 94% (aspect of implementation), and effectiveness in learning management of 94% (aspect of teacher ability to manage learning). Developing interest-based teaching materials is a strategic step to improve students' structure and mental models as prospective teachers, including conceptual understanding and intrinsic motivation. Thus, empowerment of interest influences students' thinking ability, which also helps them experience cognitive transformation as an improvement in mental structure and model in understanding context. This research is also a provision to face various global challenges that are increasingly complex and connected.

Abstract

This study aimed to assess high school student’s understanding of Banjarmasin by Rasch modeling, preci-sely the cognitive aspect. The research method was descriptive with a quantitative approach to assess the pattern of reactions and symptoms of Rasch data. According to the research findings, the person reliability (students) was +0.66 based on the Rasch modeling analysis, with the criterion satisfactory, indicating that the students knowledge was adequate. At the same time, Cronbachs’ alpha score had a value of +0.71 and met the criteria of excellent. In addition, the students with the highest level of understanding were coded 127P12B with a logit value (person measure) of 2.52 and average students with logit value of -0.77 or <0. In contrast, the students with low abilities were coded 030P10B and 059L11B (same logit value, -3.27 or <0). Other data were INFIT MNSQ and OUTFIT MNSQ (person) with average values of +0.99 and +1.14 (closer to 1, the better), while the INFIT and OUTFIT ZSTD values were -0.1 and 0.0 respectively (closer to 0, better). The most difficult question was Q16, which had a logit score of 1.96; students’ logit values carried this question. Students were regarded to have appropriate knowledge even though their ability excee-ded the problem ability. In conclusion, the Rasch model-based pre-learning evaluation was found to be useful in measuring students’ cognitive grasp of chemical bonding material. This study could serve as the primary reference for teachers in assessing students’ level of knowledge before they begin learning. In addi-tion to interpreting student knowledge through various Rasch data presentations, a study of the structure of questions with varying difficulty levels could be used to assess the full group of students’ understanding of chemistry.
