Penerapan Inkuiri Terbimbing Berbasis Pendekatan Kontekstual Untuk Meningkatkan Keterampilan Berpikir Kritis Peserta Didik Pada Materi Laju Reaksi

Implementation of Guided Inquiry Based On Contextual Approach To Improve Students Critical Thinking Skills On Reaction Rate Material

Penelitian ini bertujuan untuk mendeskripsikan peningkatan keterampilan berpikir kritis peserta didik pada materi laju reaksi melalui penerapan model pembelajaran inkuiri terbimbing berbasis pendekatan kontekstual. Sasaran penelitian ini yaitu peserta didik kelas XI MIA 7 SMA Negeri 1 Gedangan dengan desain penelitian yang digunakan yaitu One Group Pretest-Posttest Design. Metode pengumpulan data yang digunakan yaitu metode observasi, tes, dan angket respon. Instrumen penelitian yang digunakan yaitu lembar tes keterampilan berpikir kritis, lembar observasi aktivitas peserta didik, lembar keterlaksanaan model pembelajaran, dan lembar angket respon peserta didik. Data dianalisis dengan mengggunakan teknik kuantitaif dengan berbantuan SPSS 23. Hasil penelitian menunjukkan bahwa (1) Persentase keterlaksanaan model pembelajaran inkuiri terbimbing dengan pendekatan berbasis kontekstual pada pertemuan I dan II yaitu 98,66% (sangat baik) dan 99,48% (sangat baik). (2) Aktivitas relevan peserta didik pada pertemuan I yaitu 98,06% dan pada pertemuan II yaitu 97,78%. (3) Keterampilan berpikir kritis peserta didik berhasil ditingkatkan dengan rata-rata gain skor pada indikator interpretasi yaitu 0,85 (tinggi), indikator inferensi yaitu 0,82 (tinggi), indikator analisis yaitu 0,77 (tinggi), dan indikator eksplanasi yaitu 0,75 (tinggi). (4) Respon positif peserta didik terhadap penerapan model pembelajaran yaitu 96,35% (sangat baik). Hasil penelitian tersebut menunjukkan bahwa keterampilan berpikir kritis peserta didik pada materi laju reaksi berhasil ditingkatkan melalui penerapan model pembelajaran inkuiri terbimbing berbasis pendekatan kontekstual.

The purpose of this study is to describe the improvement of students' critical thinking skills on the reaction rate material by implementing a guided inquiry based on a contextual approach. The subjects were students of class XI MIA 7 SMA Negeri 1 Gedangan with a one-group pretest-posttest research design. The methods used to collect data are observations, tests, and response questionnaires. The research instruments used were critical thinking skills test sheets, observation sheet of learning model implementation, students activity observation sheets, and students response questionnaires. Data analysis was carried out using quantitative techniques assisted by SPSS 23. The results showed that (1) The percentage of the implementation of the guided inquiry with a contextual-based approach at I and II meetings is 98.66% (very good) and 99.48% (very good). (2) The relevant activities of students at I meeting is 98.06% and at II meeting is 97.78%. (3) Students' critical thinking skills are successfully improved with an average gain score on the interpretation indicator is 0.85 (high), the inference indicator is 0.82 (high), the analysis indicator is 0.77 (high), and explanation indicator is 0.75 (high). (4) Students' positive response to the learning model implementation is 96.35% (very good). The results showed that students critical thinking skills on the reaction rate material were successfully improved by implementing a guided inquiry learning model based on a contextual approach.
