Abstract

One of the 21st century life skills that needs to be developed in the education process is critical thinking skills. The importance of being trained in critical thinking skills in learning science is motivated by the results of the 2015 PISA test. critical thinking as 'the correct way of assessing statements' and 'reasonable reflective thinking focused on deciding what to believe or do'. In this study, indicators of critical thinking skills measured are providing simple explanations, building basic skills, providing further explanations, and concluding. One potential learning approach to help students become actively involved in learning activities and be able to improve critical thinking skills is the STEM approach. The purpose of this research is to develop a STEM approach digital book with certain characteristics, determine its validity, its practicality, and its effectiveness of the product towards improving students' critical thinking skills. This study uses a development plan from Sugiyono. The subjects of this research are the 8th graders of SMPN 26 Semarang, academic year 2019/2020. The sample as an experimental class (the product is applied in the learning process) is VIII B class, and the control class (used ordinary textbooks) is VIII D class. Data analysis techniques used in this study include descriptive data analysis related to the validity and practicality of the product, while to find out the effectiveness of the product used a normalized N-gain test and a two-sample t-test. Results show that (1) the characteristics of the digital book contained all components of the STEM approach which included aspects of science, technology, engineering, and mathematics (2) the developed digital book has valid criteria regarding to the material, media and language aspects (3) digital book developed effectively to improve students' critical thinking skills, and (4) the practicality of using digital book is considered very good by students and teachers).

Abstract

Penelitian ini bertujuan untuk mengetahui tingkat miskonsepsi siswa pada materi struktur atom menggunakan instrumen tes diagnostic multiple choice berbantuan CRI (Certainty of Response Index). Penelitian dilakukan di SMA Negeri 2 Demak dengan teknik pengambilan sampel purposive sampling dengan pertimbangan kelas rata-rata hasil belajar tertinggi yaitu kelas X MIPA 1. Metode yang digunakan dalam penelitian ini menggunakan rancangan analisis deskriptif dengan teknik pengumpulan data melalui tes tertulis. Hasil penelitian ini menunjukkan tingkat pencapaian konsepsi siswa pada materi struktur atom yaitu sebanyak 37,03% siswa pada kelompok tahu konsep, 28,91% siswa pada kelompok tidak tahu konsep, dan 34,06% siswa pada kelompok miskonsepsi. Persentase tingkat miskonsepsi siswa pada materi struktur atom tersebar pada setiap sub konsep. Secara berurutan persentase miskonsepsi siswa untuk sub konsep teori atom Dalton, teori atom Thomson, teori atom Rutherford, teori atom Bohr, dan teori atom mekanika gelombang adalah 24,85%; 27,27%; 45,45%; 39,395; dan 33,33%. Miskonsepsi terjadi pada seluruh sub konsep pada materi struktur atom dengan persentase tertinggi pada sub konsep teori atom Rutherford yaitu sebesar 45,45%.

Abstract

Penelitian ini bertujuan untuk mengetahui keefektifan model Think Pair Square (TPS) berbasis Guided Inquiry pada tema sistem transportasi terhadap peningkatan hasil belajar kognitif dan sikap ilmiah siswa, serta untuk mengetahui tanggapan siswa terhadap model pembelajaran tersebut.Jenis penelitian ini yaitu quasi experimentdengan desain non-equivalent control group design. Sampel penelitian ini diambil dengan teknik purposive sampling, kelas VIII G (kelas eksperimen) yang diberi perlakuan model TPS berbasis guided inquiry dan kelas VIII H (kelas kontrol) yang diberi perlakuan model TPS berbasis structured inquiry. Data diambil dengan metode tes(pre-test dan post-test), observasi (sikap ilmiah), dan angket (tanggapan tentang model dan penilaian diri). Uji hipotesis yang dipakai yaitu uji perbedaan dua rata-rata (hasil belajar kognitif dan sikap ilmiah).Hasil penelitian menunjukkan bahwa rerata hasil belajar (post-test)kelas eksperimen lebih tinggi dari kelas kontrol (78,80> 76,13). Nilai N-gain kedua kelas masing-masing meningkat sebesar 0,56 dan 0,48 (kategori sedang). Ketuntasan klasikal kelas eksperimen (96,88%) > kelas kontrol (90,32%). Dari uji hipotesis, diperoleh thitung> ttabel (1,704> 1,671). Rata-rata nilai sikap ilmiah kelas eksperimen (79,3) lebih tinggi darikelas kontrol (77,6). Dari uji hipotesis diperoleh phitung<α (0,044< 0,05).Tanggapan siswa tentang model TPSberbasis guided inquirydinyatakan efektif (80,78). Hasil penelitian tersebut menunjukkan bahwa model TPSberbasis guided inquirypada tema sistem transportasi efektif terhadap peningkatan hasil belajar kognitif dan sikap ilmiah siswa. The aim of this study was to examine the effectiveness of Guided Inquiry based Think Pair Square (TPS) on the chapter of transport system. This study was concerned on raisingstudents’ cognitive skill and scientific attitude, alsoon finding outof the students’ response. The type of this study was quasi experimental design, especially non-equivalent control group design.The samplesof this study wasgrade VIII G (experiment) and VII H (control) of SMPN 26 Semarang, taken with purpossive sampling method. The data was taken by test method (pre-test andpost-test), observation (scientific attitude), also questionnaire (students’ responses and self-assesment). The results showed that the average of experiment classis higher than the control ( (78,80 > 76.13). This result proved by the t-test which achieved tvalue> ttable (1.704> 1.671). The N-gain value of both classes were increased by 0.56 and 0.48 (medium category). The classical completeness of experimental (96.88%)> controls (90.32%). The average value of the scientific attitudesof experimental (79.3) and control (77.6). This result verified by the Mann-Whitney test which obtained pvalue<α (0.044 < 0.05).The students’ responses about Guided Inquiry based TPSwas effective (80.78). In conclusion, students in the experimental group had better cognitives skill of Transport system, and more positive attitude toward Guided Inquiry based TPS.
