Thinking Disposition

This study was aimed at producing an argument-based science teaching textbook for junior high school students to improve student’s critical thinking disposition and critical thinking skill. This text book was produced by following Borg and Gall’s (1983). Research and development model for three years. The first year research collected information (need analysis) used to design the draft of the product in the form of argument-based science text book for junior high school to improve student’s disposition and critical thinking skill. The product of the first year research was in the form of a draft of the argument-based science textbook. The second year research tried out the argument-based science text book for junior high school in a limited scope, conducted in three SMP’s in Bali province. This try-out used pretest-posttest one group design. The number of students involved in the second year research was 88 students. The result of the second year research showed that the argument-based science text book for junior high school could improve students’ disposition skill by 21.48% and critical thinking skill by 57.22%. The third year research tried out the argument-based science text book for junior high on a large scale in three SMP’s in Bali province. The study used the pretest--posttest one group design. The number of students involved was 194 students, the control group and experiment group had 97 students respectively.  As the comparison the text book entitled Buku Ajar IPA SMP Kurikulum 2013 was used. The data obtained from this third year research were in the form of scores for critical thinking disposition and critical thinking skill. These data were analyzed using multivariate covariance analysis at 5% level of significance. The large scale tries out in the third year was aimed at determining the effectiveness of the argument-based science teaching textbook for junior high school to improve student’s disposition and critical thinking skill. The results showed that there was a significant effect of the argument-based science teaching text book for junior high school students to improve student’s disposition and critical thinking skill on the student’s critical thinking disposition and critical thinking skill both simultaneously and partially or individually. Based on the test of means difference, the argument-based science teaching text book for junior high school students was better than Buku Ajar IPA SMP Kurikulum 2013 in improving the student’s critical thinking disposition and critical thinking skill both simultaneously and partially.

Critical Thinking Skill

Until recently, not only students in middle high schools but also in a university have difficulties in understanding either mathematical representations or physical concept behind scientific phenomena. Those difficulties are then associated with a low level of critical thinking. For instance, in physics, it seems to be not easy for students to attain proper relation among wave speed, wavelength, and frequency. This unproper understanding contributes to students’ low critical thinking skill. One of the most effective ways to overcome the problem is to use student-centred learning with interactive, animated, and game-like learning experiences. Guided inquiry learning and a freely App “Physics Education Technology (PhET)” are believed to meet the criteria. This study focused on the students’ knowledge construction process to be able to think critically the wave-related concepts. This PhET-assisted guided inquiry learning strategy was addressed to 25 students at a junior high school in Indonesia. The objective is to explore the stages of inquiry learning approach using PhET, especially on training them to attain their critical thinking skill. This is a qualitative study that purely involves in-class observation. The lesson plan and student worksheets were prepared as the research instruments. As the results, we found that the use of PhET in the guided inquiry learning model can help students acquire to learn the concept of wave speed, wavelength, and frequency with critical thinking.

Penelitian ini bertujuan untuk mendeskripsikan keefektifan pembelajaran matematika dengan pendekatan metakognitif, pendekatan konvensional, dan perbandingan keefektifan pembelajaran matematika dengan pendekatan metakognitif dan pendekatan konvensional ditinjau dari prestasi belajar, kemampuan berpikir kritis, dan minat belajar matematika siswa. Penelitian ini merupakan penelitian eksperimen semu. Populasi penelitian ini adalah seluruh siswa kelas VIII SMP Negeri 3 Banguntapan yang terdiri atas delapan kelas. Teknik pengumpulan data dalam penelitian ini adalah tes dan non tes sedangkan instrumen yang digunakan untuk mengumpulkan data berupa soal tes prestasi belajar dan soal tes kemampuan berpikir kritis, serta angket minat belajar matematika siswa. Data dalam penelitian ini diuji menggunakan uji proporsi dengan hampiran normal. Hasil penelitian ini mengindikasikan bahwa pendekatan metakognitif efektif ditinjau dari prestasi belajar siswa dan minat belajar matematika siswa, namun tidak efektif ditinjau dari kemampuan berpikir kritis siswa. Pendekatan konvensional tidak efektif ditinjau dari prestasi belajar siswa dan kemampuan berpikir kritis, namun tidak efektif ditinjau dari minat belajar matematka siswa. Selain itu diperoleh pula hasil bahwa pendekatan metakognitif lebih efektif dibanding pendekatan konvensional ditinjau dari prestasi belajar siswa dan kemampuan berpikir kritis, namun tidak lebih efektif dibanding ditinjau dari minat belajar matematika siswa. Kata kunci: pendekatan metakognitif, pendekatan konvensional, prestasi belajar, kemampuan berpikir kritis, dan minat belajar matematika siswa.   THE EFFECTIVENESS OF METACOGNITIVE APPROACH ACCORDING TO LEARNING ACHIEVEMENT, CRITICAL THINKING SKILL, AND INTEREST IN LEARNING MATHEMATICS Abstract This study is aimed to describe the effectiveness of metacognitive approach, the effectiveness of conventional approach, and the effectiveness of the comparison between metacognitive approach and conventional approach according to learning achievement, critical thinking skill, and student’s interest in learning mathematics. This study was a quasi experiment whose object was all the 8th graders of State Junior High School 3 Banguntapan. The instrument to collect the data was a test to indicate the learning achievement and critical thinking skill, and also a questionnaire to reveal student’s interest in learning mathematics. The data were analyzed using the proportion test with normal approach. The results of the study indicate that the metacognitive approach is effective according to learning achievement and student’s interest in learning mathematics but ineffective according to critical thinking skill. The conventional approach is ineffective according to learning achievement and critical thinking skill, but effective according to student’s interest in learning mathematics; the metacognitive approach is more effective than conventional approach according to learning achievement and critical thinking skill but less effective than conventional approach according to student’s interest in learning mathematics. Keywords: metacognitive approach, conventional approach, learning achievement, critical thinking skill, student’s interest in learning mathematics.
