Development and Validation of Discovery-Based Modules in Teaching Chemistry

Abstract

This study is focused on developing and validating the discovery-based modules in chemistry. This exploration was initiated in response to the criminology student's least-learned concepts in the general (organic) chemistry course. A descriptive–developmental approach was utilized and guided by the Analysis-Design-Development-Implementation-Evaluation (ADDIE) model in the development and validation of the discovery-based modules. In the study, two discovery-based modules were developed. Each module had the following parts: a pre-test, an overview, safety precautions, preparation, a review, the activity itself, a discussion after the activity, a post-activity test, an application, and a reference. Five (5) chemistry teacher experts and five (5) criminology student-users evaluated the aspects of the discovery-based modules using the validation and evaluation forms of the study. The researcher interviewed the criminology student-users using the validated interview guide questions to determine their feedback using the modules. Findings revealed that both chemistry teacher experts and criminology student-users rated the two developed discovery-based modules as excellent and strongly agreed on all pertaining aspects of the modules, in terms of objectives, content, format and language, presentation, and usefulness. The feedback of the student-users revealed interactive, well-designed, discovery-based, and outcome-based themes perceived as the characteristics of the developed chemistry modules. Therefore, it was concluded that the developed discovery-based modules in chemistry are valid, acceptable, and could be used as supplementary material for criminology students and further recommended for possible replication to cover the other least-learned chemistry concepts.

Analisis Pendahuluan sebagai Dasar Pengembangan Modul Kimia Organik Bermuatan Hasil Riset untuk Mahasiswa Pendidikan Kimia

“…Penggunaan modul sebagai bahan ajar dapat membantu proses pembelajaran peserta didik sehingga mereka bisa belajar secara mandiri. Hal ini dikarenakan di dalam modul terdapat petunjuk untuk belajar sendiri (Ramadani et al, 2020) (D. Medina & G. Baraquia, 2023. Hal ini disebabkan karena salah satu faktor keberhasilan dalam kegiatan pembelajaran sangat bergantung pada penggunaan sumber belajar atau media yang digunakan selama proses pembelajaran (Ramadani et al, 2020).…”
