Availability and Utilisation of Science Laboratory Facilities on Science Teacher-Trainees’ Pedagogical Content Knowledge in Science
Full text linkThis study assessed final-year science teacher-trainee perceptions of the impact of the availability and utilization of laboratory facilities on science students' pedagogical content knowledge (PCK) in science at Accra and Ada Colleges of Education. This research was motivated by an initial study that stated that the majority of junior high school science teachers were unable to teach science effectively so it was easier for students to understand. This research used a quantitative approach with a cross-sectional descriptive survey design involving 62 intern teachers, 15 science tutors, and two school principals. The research instrument (tutor and teacher questionnaire) was declared suitable for use after a slight revision with the Validity and Reliability scores of 0.84 and 0.86. The research revealed that final-year science teacher candidates at the Accra College of Education were of the opinion that the availability and utilization of laboratory facilities had a moderate but neutral impact on PCK in science, in contrast to the results of research by science teachers at Ada College which stated that the availability and use of Laboratory facilities have a high and positive impact on PCK Science. It is recommended that science tutors engage science trainee teachers in efficient hands-on activities, and also focus on on-campus and off-campus practicums to develop the training of PCK science trainee teachers.Keywords: Laboratory Facilities, Science Teacher-Trainees, Pedagogical Content Knowledge (PCK in Science, Impact of Availability and UtilisationStudi ini menilai persepsi guru-peserta pelatihan sains tahun terakhir tentang dampak ketersediaan dan pemanfaatan fasilitas laboratorium terhadap pengetahuan konten pedagogis siswa sains (PCK) dalam sains di Accra dan Ada Colleges of Education. Penelitian ini dilatarbelakangi oleh penelitian awal yang menyatakan bahwa sebagian besar guru IPA SMP belum mampu mengajarkan IPA secara efektif sehingga lebih mudah dipahami oleh siswa. Penelitian ini menggunakan pendekatan kuantitatif dengan desain survei deskriptif cross-sectional yang melibatkan 62 orang guru magang, 15 orang tutor IPA, dan dua orang kepala sekolah. Instrumen penelitian (angket tutor dan guru) dinyatakan layak digunakan setelah dilakukan sedikit revisi dengan skor Validitas dan Reliabilitas sebesar 0,84 dan 0,86. Hasil penelitian mengungkapkan bahwa calon guru IPA tingkat akhir di Accra College of Education berpendapat bahwa ketersediaan dan pemanfaatan fasilitas laboratorium berdampak sedang namun netral terhadap PCK bidang IPA, berbeda dengan hasil penelitian guru IPA di Ada College yang menyatakan bahwa ketersediaan dan pemanfaatan fasilitas Laboratorium memberikan dampak yang tinggi dan positif terhadap PCK Sains. Disarankan agar tutor sains melibatkan guru peserta pelatihan sains dalam kegiatan praktik langsung yang efisien, dan juga fokus pada praktik di dalam kampus dan di luar kampus untuk mengembangkan pelatihan guru peserta pelatihan sains PCK

Critical Thinking of Prospective Teachers In Solving Math Problems In Terms of Learning Styles
Full text linkThis study aims to identify how the process of critical thinking of prospective teachers in solving mathematical problems in the Department of Mathematics Education, Faculty of Science and Technology, Walisongo State Islamic University, is viewed from a qualitative learning style. The purposive sampling method was used to determine six prospective teachers as research subjects. Each visual, auditory, and kinesthetic learning style is represented by 2 subjects. The auxiliary instruments in this study consisted of a learning style questionnaire, a critical thinking ability test, and an interview guide. Critical thinking indicators were developed through consideration of the main elements of FRISCO, the level of cognitive thinking according to Bloom and the Steps of Problem Solving According to John Dewey. Data processing through the stages of data collection, data reduction, and data verification with the triangulation method. The results of the study show that auditory and kinesthetic learning styles have lower critical thinking process characteristics than visual learning styles in solving math problems. From the interview process it was revealed that the ability to argue based on valid and logical facts, all types of learning styles is still quite low. However, all three have strong potential to develop critical thinking skills through stimulation from educators

Full text linkGame Penjelajah Ruang (The Space Exploration Game, Ganjaran) is a learning media in the form of an Android-based educational game to practice the mathematical reasoning skills of class VIII students on SPLDV questions. The purpose of this study was to describe students' mathematical reasoning abilities in solving SPLDV questions on Android-based of Ganjaran. The students' mathematical reasoning ability can be seen from the results of working on the SPLDV questions by students which are made based on mathematical reasoning indicators. The type of research used is descriptive qualitative research. The subjects of this study were students of class VIII SMP Negeri 2 Krian as many as 4 students who had played the Ganjaran. The test instrument used in this study was a 5-point SPLDV reasoning question with short answers. From the results of the study, the average value of students' mathematical reasoning abilities was 56.25 which was quite sufficient. Overall, the indicator of mathematical reasoning ability that is mostly mastered by students is indicator c (drawing conclusions, compiling evidence, providing reasons or evidence for the correctness of the solution), while the indicator of student mathematical reasoning that is less mastered by students is indicator a (proposing conjectures)
Development Mathematics Realistic Education Worksheet Based on Ethnomathematics in Elementary School
Full text linkLearning mathematics at the elementary school level is an interesting to research. This is due to the mathematical material that requires children to reason mathematically. Many learning models are introduced to students, but are not in accordance with the surrounding cultural conditions. Culture is something that is close and real in students' lives. The purpose of this research is to see the effectiveness of ethnomathematics-based realistic mathematics learning in elementary school. Realistic mathematics learning model based on ethnomathematics in elementary schools can be implemented with the help of worksheets that contain guided reinvention and didactical phenomenology and self-developed models with ethnomathematical-based materials in the form of batik typical of Pekalongan. This research is a research and development research which includes a define, design, development, and dissemination. Data collection techniques were carried out using observation, interviews, questionnaires, tests, and documentation methods. The data analysis technique was carried out with the Independent t-test to determine the effectiveness of the learning model. The results of this study indicate that 1) LKS is feasible to use as a source of practical, valid, and effective mathematics learning tools, 2) ethnomathematics-based realistic mathematics learning is effective viewed from student learning outcomes in elementary school
