Abstract

Objective: Students are said to understand the concept comprehensively if they master the concepts from dimensions of ontology, epistemology, and axiology. One of the topics that still needs to be clarified is chemical equilibrium. Therefore, it is necessary to develop instruments to diagnose conceptions about the chemical concepts taught. The STDT is one of the instruments that will be developed by researchers, which contains three scientific questions to identify misconceptions in chemical equilibrium. Method: This development research used the ADDIE model. The instrument's effectiveness refers to the empirical validity after applying the STDT instrument. The effectiveness of the STDT instrument was obtained through the correlation of misconceptions experienced by students with the level of difficulty of the items. The STDT instrument was applied to 86 students. Results: The percentage of students who experienced the highest misconceptions occurred in the chemical equilibrium section of the equilibrium shift due to the influence of a catalyst. In each item of questions, most students need more knowledge or knowledge. The composition of the difficulty of these items should be considered from the start of the instrument's preparation. In the developed STDT instrument, the item difficulty obtained from empirical trials on students did not meet the ideal conditions for the composition of the item difficulty level. Novelty: The resulting instrument for detecting misconceptions. It is a tier diagnostic test that is integrated with three scientific questions.

Abstract

Objective: This study aims to develop a lecture set designed to reduce the occurrence of logical fallacies by training students' argumentation skills. Method: The lecture sets were developed to refer to the stages of the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). Validity was validated by three validators on student activity sheets and argumentative ability assessment sheets. The validity of the test results was obtained based on the mode of calculation and the percentage of agreement between validators. Results: The lecture sets are structured by containing six types of logical fallacies, namely relative privation, blind authority fallacy, hasty generalization, questionable cause fallacy, reification fallacy, and non sequitur, and includes general chemistry lecture material, namely stoichiometry, atomic structure, periodicity of elements, chemical bonds, the concentration of the solution, the equilibrium of ions in the solution, and the colligative properties of the solution. The chemistry lecture sets for reducing logical fallacies in arguing has been declared valid by the validator. Novelty: The results of this study can be used as a reference by teachers, lecturers, or other researchers who wish to study more about logical fallacies.
