ABSTRACT
This study was conducted to determine the influence of guided discovery and group investigation learning strategies on science process skills and higher order thinking skills (HOTS) of senior high school students in SMA Negeri 1 Kutacane-Indonesia. This research was quasi experimental with the samples of three classes, determined by purposive sampling. Students in class X IPA Plus were taught by guided discovery and class X IPA 1 were taught by group investigation as experimental groups, and class X IPA Inti were taught by conventional learning strategy as control group. The research instruments were the essay tests to collect the data of science process skills and HOTS. Analysis of Covariate (ANCOVA) was used to analyze the data by using SPSS 22.0. The results showed that there was a significant influence of learning strategies on student’s science process skill (F = 141.52; P = 0.00). The students’ science process skills taught by guided discovery (84.49 ± 5.92) was significantly higher than student’s science process skills of group investigation (78.76 ± 5.76) and conventional learning strategy (62.08 ± 4.45). There was also a significant influence of learning strategies on student’s HOTS (F = 117.86; P = 0.00). Students’ HOTS taught by guided discovery (81.76 ± 4.48) was significantly higher than students’ HOTS by group investigation (71.31 ± 5.47) and conventional learning strategy (64.31 ± 4.61). As a follow-up, teachers were suggested to apply guided discovery learning strategy in teaching ecosystem topic as an effort to improve students’ science process skills and higher order thinking skills.
Key words: Guided Discovery learning strategy, Group Investigation, science process skills, higher order thinking skills
