Abstract

This research aims to determine the validity of the conceptual identification assessment sheet and argumentation skills on chemical equilibrium material. This research uses the Research and Development type of research. The development model uses the ADDIE model by applying the Analyze, Design and Develop stages. The research subject is SMAN 16 Surabaya. Later, this research will use qualitative and quantitative data analysis. The validation results of the product validity assessment show that the data on the material aspect is in the very good category which is get mode score 4, the construct aspect is in the good category which is get mode score 3, and the language aspect is in the good category which is get mode score 4. The results of the teacher's response to the assessment instruments developed are good and can be used.

Abstract

Research into misconceptions is crucial in the field of education, particularly in subjects like chemistry, which are complex and prone to misunderstandings. Misconceptions—ideas held by individuals that deviate from established scientific understanding—can arise from various sources, including students, teachers, textbooks, and instructional methods. These inaccuracies can hinder effective learning and need to be addressed to enhance educational outcomes. Identifying and remediating misconceptions is challenging, requiring specialized tools and methods. Therefore, research into misconceptions aims to uncover and correct these misunderstandings to improve teaching strategies and student comprehension. Therefore, the research in this article is concerned with the practicality of the application of chemical representation diagnostic tests to identify chemical misconceptions, particularly on chemical equilibrium and chemical bonding materials. This research was carried out at Surabaya State University participated by 24 students from the Chemistry Education Study Program. In this research, the practicality of the chemical misconception diagnostic test application was obtained at 98.6% which indicates that the application is practical to use. In addition, obtained data on student diagnostic results, namely: 88.3% did not understand the concept; 10.4% had misconceptions; and 1.3% understood the concept on the topic of chemical bonding. Keywords: misconceptions, five-tier diagnostic test, chemical bonding, online application

Abstract

This study aims to produce a valid four-tier multiple-choice diagnostic test instrument based on validity and reliability and to detect students misconceptions the concept of chemical bonds using the developed instrument. The research design used in this development uses research and development (R&D) of Thiagarajan's modified 4D model consisting of four stages, namely the stages (define, design, develop, disseminate). Based on the results of the study, it can be concluded that (1) the validity of the instrument who reviewed from the content and construct aspects has a score mode of 4, (2) the Cronbach Alpha value is 0.825 which means it is reliable and (3) the misconception profile owned by students for each sub-material of ionic bonds is 33%, metal bonds are 40% and covalent bonds are 51.51%. Based on the results of validity and reliability, the diagnostic test instrument developed can be declared valid for use.

Abstract

This research aims to describe the validity of the Electronic Learner Activity Sheet (E-LAPD) for reaction rate to improve critical thinking skills with the 7-E learning cycle learning model developed. The development model in this research is ADDIE with four stages Analyze, Design, Development, and Evaluate. The validation results were analyzed based on the mode in each aspect. Based on the validation results, it was found that the developed reaction rate E-LAPD has a good category with a score of 3 on the content validity aspect and a good category with a score of 3 on construct validity. Furthermore, reaction rate electronic learner activity sheet can be used in the learning process in the classroom to determine the practically and effectiveness of the developed reaction rate electronic worksheet
