UPAYA MENINGKATKAN KEAKTIFAN DAN HASIL BELAJAR PADA MATA PELAJARAN IPAS DENGAN METODE GROUP INVESTIGATION PADA SISWA KELAS IV MI IMAM PURO BRENGGONG

Abstract

This study aims to: 1) Determine the application of the GI method in science. 2)

Determine the increase in student engagement in science. 3) Determine the

improvement in student learning outcomes in science. This study used a classroom

action research (CAR) approach, implemented in two cycles, each consisting of

planning, implementation, observation, and reflection, using the Group Investigation

method. The study subjects were 20 students, consisting of 10 boys and 10 girls. Data

collection techniques included observation, interviews, tests, and documentation. Data

analysis was conducted qualitatively and quantitatively. The results showed that: 1) The

implementation of the GI method was carried out through six stages: grouping,

planning, investigation, organizing, presenting, and evaluation. 2) The increase in

student engagement was evident from observations: 36% in the pre-cycle, increasing to

58% in the first meeting of cycle I and 65% in the second meeting of cycle I, reaching

78% in the first meeting of cycle II and 93% in the second meeting of cycle II. The

category of student activity developed from “less active” to “quite active”, to “very

active”. 3) Student learning outcomes also experienced a significant increase. With an

average score of 69 in the pre-cycle, 74 in cycle I, and 88 in cycle II. The percentage of

classical completion in cycle II reached 95%, exceeding the learning objective

achievement criteria (KKTP). Thus, the application of the Group Investigation method

has proven effective in increasing student activity and learning outcomes in the subject

of science.
