Abstract

Understanding the concept of ionic and covalent compounds is a fundamental foundation in basic chemistry education, as these concepts underpin the structure, properties of compounds, and their applications in daily life. Misconceptions about ionic and covalent bonding are common and negatively impact students' ability to analyze compound properties, critical thinking skills, and scientific argumentation. On the other hand, Generation Z demonstrates weaknesses in deeply reflecting on conceptual errors, as evident in basic chemistry lab reports. Lab reports can reveal both the depth of understanding and the patterns of conceptual errors experienced by students. This study aims to analyze students' conceptual errors related to ionic and covalent compounds in Basic Chemistry I lab reports. The research employs a case study method with a qualitative descriptive approach. The researcher acts as an instrument to assess students' conceptual errors by discussing their lab reports. The findings reveal three conceptual errors in the sub-topic of melting point comparison and five conceptual errors in the sub-topic of solubility.

Abstract

Students in teacher education programs often experience difficulties in understanding statistical concepts due to their abstract nature and limited connection to real-world contexts. Nevertheless, statistics serves as a fundamental foundation for developing quantitative thinking skills in science education. This study aimed to develop the KIMATIKA Student Worksheet (Lembar Kerja Mahasiswa/LKM), which integrates mathematics and chemistry concepts in the Educational Statistics course to enhance students’ quantitative understanding. The study employed a Research and Development (R&D) method by adapting the ADDIE model and was conducted up to the development stage. The results of expert judgment validation indicated that the KIMATIKA worksheet demonstrated a very high level of feasibility. The material experts’ evaluation yielded an average score of 4.74 with an ideality percentage of 94.71% (Very Good), while the media experts’ evaluation resulted in an average score of 4.81 with an ideality percentage of 96.25% (Very Good). In addition, students’ evaluations produced an overall average score of 4.58 with an ideality percentage of 91.51%. These findings indicate that the KIMATIKA worksheet is substantively sound, well-structured in its presentation, linguistically appropriate, and visually effective, and it received very positive responses from students in its implementation.
