Abstract

Stoichiometry is one of the essential chemistry topics that is an abstract concept, involves complex calculations, and is related to other chemical concepts. It can cause not a few students to have difficulty learning it. Scaffolding is needed in the learning process of stoichiometry concepts to help students understand concepts more easily and improve learning outcomes. This research aims to determine differences in students' cognitive learning outcomes on the stoichiometry topic after implementing the IMWR scaffolding model. This research used experimental research with the one-group pretest-postest design. Respondents were 32 high school students who were determined by purposive sampling. The instrument test consisted of 32 items of essays that were valid and reliable. Data is collected and carried out through pretest and posttest. The differences in students' cognitive learning outcomes were analyzed descriptively using the N-gain test and statistical analysis using the paired sample t-test. The paired sample t-test showed a significance value of 0.000 (sig. <0.05), meaning there were differences in student learning outcomes after implementing the IMWR Scaffolding learning model. However, the resulting difference is not significant and is in a low category (N-gain 0.27). Implementing IMWR scaffolding needs to be designed as best as possible by paying attention to students' character to help students understand the concept using procedural knowledge, which impacts better learning outcomes.

Abstract

Atom, ion, dan molekul merupakan salah satu konsep dasar kimia yang bersifat abstrak dan saling berkaitan dengan konsep lainnya, serta menitikberatkan pada definisi konsep dan perhitungan. Hal tersebut menimbulkan adanya miskonsepsi. Peserta didik yang mengalami miskonsepsi pada konsep tersebut, maka akan kesulitan memahami konsep selanjutnya seperti persamaan reaksi, tata nama senyawa, stoikiometri, serta ikatan kimia. Miskonsepsi perlu diatasi agar pengajar dapat menghindari kesalahan pada proses pembelajaran yang menekankan pada konsep yang dianggap sulit. Oleh karena itu, dilakukan pengembangan instrumen untuk mengidentifikasi miskonsepsi peserta didik. Instrumen three tier test dinyatakan valid dan reliabel, serta dapat mengetahui tingkat konsepsi peserta didik. Hasil uji CVR melebihi 0,49 dan nilai cronbach’s alpha 0,842. Tingkat konsepsi peserta didik yaitu 43,72% memahami konsep, 13,32% kurang memahami, 8,92% miskonsepsi negatif, 12,70% miskonsepsi positif, dan 17,93% miskonsepsi.
