PENERAPAN LKPD BERBASIS TUMBUHAN Angiospermae DI LINGKUNGAN SEKOLAH TERHADAP PENGUASAAN KONSEP SISWA

Abstract

Low students’ conceptual understanding of the classification of living things indicates the need for innovative learning that connects biological concepts with the real environment surrounding students. This study aimed to analyze the effect of implementing a Student Worksheet (LKPD) based on the classification of Angiospermae plants found around the school on students’ conceptual understanding of the classification of living things. This study employed a quantitative approach using a quasi-experimental method with a Nonequivalent Control Group Design. The sample consisted of an experimental class that received learning using an LKPD based on the classification of Angiospermae plants with a scientific approach and a control class that received conventional learning using the lecture method without the research LKPD. Data were collected through a conceptual understanding test, learning implementation observation sheets, and student response questionnaires. Data analysis included validity, reliability, item difficulty, item discrimination, N Gain, normality, homogeneity, hypothesis testing, and effect size analyses. The results showed that the improvement in conceptual understanding in the experimental class was better than that in the control class, with a significant difference between the two classes. The effect of LKPD implementation was categorized as large, while learning implementation and student responses were categorized as very good. Thus, the implementation of an LKPD based on the classification of Angiospermae plants around the school using a scientific approach can be an alternative contextual, active, and meaningful learning strategy for improving students’ conceptual understanding.
