Analisis Miskonsepsi Peserta Didik Menggunakan Certainty of Response Index (CRI) pada Materi Stoikiometri

Abstract

Many students are misconception, so the researchers do research with the aims to analyze the level of understanding of the participants’ concept students and the factors causing students’ misconceptions on the subject matter stoichiometry. Data collection uses open-ended diagnostic tests with a scale CRI with 18 numbers and interviews. The results showed the percentage of understanding concepts of 21% with a low percentage category, understand the concept but not sure at 7%, with the low category, the percentage of misconceptions of 12% with low categories and percentage do not understand the concept of 61% with a high category. Factors that cause misconception include a) students; c) how to teach.

Development of MISTION Software to Detect and Reduce Students' Misconception with Conceptual Change Text Strategy on Stoichiometry Materials

“…Students are very prone to misconceptions, especially in the material that has many abstract concepts, such as stoichiometry. It is supported by various research that shows many students experience misconceptions on stoichiometric material (Djarwo, 2020;Wiwiana et al, 2020;Wulandari & Rusmini, 2020). Concepts in chemistry are interrelated, so the understanding level of one concept affects others.…”

“…Stoichiometry is a difficult material because of the many abstract concepts and concepts related to the ratio or proportion of reactants and products in chemical calculations, giving rise to misconceptions about the stoichiometric concept (Nikmawati et al, 2019). It is supported by various study that shows many students experience misconceptions on stoichiometric material (Djarwo, 2020;Wiwiana et al, 2020;Wulandari & Rusmini, 2020) Identifying student misconceptions is very important for the student learning process in the future. One way to find out the misconception is by using a diagnostic test.…”
