Get PDFHigher-order thinking skills are essential skills for a pre-service teacher to have. This study aims to develop the instrument and measure the higher-order thinking skills pre-service physics teacher UIN Walisongo Semarang with science literacy-based learning using the High Order Thinking Skills instrument. The data collection method used was a test, consisting of 20 selected questions with open reasons; structured interviews with lecturers and pre-service physics teachers; and documentation to collect pre-service physics teachers’ data required for research. The test instrument developed by reacherchers and validated by expert in the field of evaluation and physics. The instrument developed was in the form of questions grids, test questions, answer keys, scoring and assessment guidelines, and guidelines for the interpretation of high order thinking skills. The results of product development obtained 14 test items representing four indicators on Simple Harmonic Motion material. The results showed that the higher-order thinking skills of pre-service physics teachers were in the poor category, with an average percentage of 39%. The highest thinking skills are in the indicators determining the period and frequency of vibrations in simple harmonic motion that is in the good category with a percentage of 60.8%. The lowest thinking skills are on the indicator of analyzing energy in simple harmonic moving objects, which are in the inferior category with a percentage of 12.8%. The results of the research show that the higher-order thinking skills of pre-service physics teachers are still low, so that lecturers need to follow up to improve higher-order thinking skills of pre-service physics teachers UIN Walisongo Semarang

Problem Based Learning Model For Increasing Problem Solving Skills In Physics Learning
Get PDFThe role of creativity in learning is more associated with problem-solving activities, meaning that creativity is measured through the ability of students to approach and solve problems. However, the PBL model has not been implemented optimally by the teacher, so that the problem solving ability and learning achievement of students have not been optimally stimulated. This research study is proposed to develop a model of Problem-Based Learning to stimulate the improvement of the skill of problem solving in physics learning for students of Senior High School. The development of Problem-Based Learning model for physics learning applied the ADDIE model. The form of observation sheets, questionnaires and question sheets were used as the instrument of data collection. The product was validated by the experts and tested on the eleventh grade students of SMA 9 Padang with a value of 3.85 very valid categories.The practicality of the learning model was determined by the implementation of learning, teacher’s response and students’ response with a value of 3.73 with category done. The effectiveness of the learning model was determined by student activities, problem solving skills and knowledge aspect. show that Asymp.C. 001 <0.05 means that Ho is rejected. The research has found a Problem-Based Learning model for physics learning which is abbreviated with the problem based learning model to physics learning (PBL-PL) . The findings indicated that the Problem-Based Learning model can stimulate the improvement of students' problem solving skills for Physics learning in Senior High School. For this reason, it is recommended for the teachers and prospective teachers to apply the Problem-Based Learning model for Physics learning in Senior High School

Get PDFThe unavailability of learner autonomy-oriented physics teaching materials which are capable of enhancing students’ science process skills (SPS) of students is becoming a hindrance in one of the public high schools in Banjarmasin, as well as the lack of SPS in students. Thus, this study was carried out with the aim to produce learning materials oriented on learner autonomy orientation to enhance students’ SPS properly. This was based on the validity, practicality, and effectiveness of the developed teaching materials in terms of learning outcomes in the students’ cognitive and psychomotor domains. This research utilized research and development method with the use of the ADDIE development model (Analyze, Design, Develop, Implement, Evaluate). The trial subjects in this study consisted of 34 students of Grade X in one of the public high schools in Banjarmasin. The data were obtained through validation sheets, lesson plan implementation sheets, SPS observation sheets, and learning outcomes tests (LOT). The results indicated that the teaching materials developed were: 1) valid, based on the results of the validator's assessments with the average score of 3.35, categorized in the “valid” category; 2) practical, based on the implementation of lesson plan with the average score of 3.66 in the very good category; 3) effective, seen from the gain score obtained of 0.67 in the “medium” category; 4) SPS achievement of 72.17 in the “good” category. It is then concluded that the learner autonomy-oriented learning materials are feasible to be implemented in classroom activities
Identification of Slip Surfaces Using the Geoelectric Imaging Method in the Kalirejo Area, Kokap District, Yogyakarta, Indonesia

From Teachers’ Views to Explore the Implementation of Energy Education in Taiwan’s Elementary Schools
Get PDFThis study intended to explore the implementation of promoting “energy education” in Taiwan’s elementary schools. The research adopted a questionnaire (Likert five-point scale) from teachers’ view in three dimensions to construct examination. The 45 participants come from 10 different primary schools distributed across Taiwan, which participate in energy education program in the second period (2015-2017). The data was analyzed by ANOVA, mean and standard deviations of the viewpoints of the participants in the energy education learning achievement of the primary schools. The first findings in this research is, the program of energy education was most effective in “energy attitude” (M=4.282, SD=0.814), followed by “energy awareness” (M=4.049, SD=0.720) and “energy behavior” (M=3.983, SD=0.875). It shows that students have positive energy attitude, but they were relatively weak at energy saving behavior. Secondly, there is statistically significant difference in overall students learning performance with urban areas are higher than rural areas. Finally, it is suggested that in addition to strengthen energy attitudes and energy awareness, we should encourage students to take action in save energy in their daily life. Furthermore, we should invest more resources to rural areas to balance the students’ performances between urban and rural areas
