The objectives of this study are to: a) Produce an Android-based Interactive Physics Mobile Learning Media (IPMLM) that is eligible for improving Higher-order Thinking Skills (HOTS) of high school students; b) Determine the effectiveness of the use of Android-based interactive physics mobile learning media with a scaffolding learning approach in improving Higher-order Thinking Skills (HOTS) for high school students. The research subjects were 1070 high school students in five regencies/cities. The technique of analyzing the data of empirical test questions used item response theory analysis by looking at the compatibility of items with the model based on the INFIT MNSQ (infit mean square) value. Extensive test data were analyzed with descriptive statistics and inferential statistics. Inferential statistics were performed using the ANOVA mixed design test with a significance level of α = 0.05. The results show that a) Android-based interactive physics mobile learning media applications and learning devices are appropriate to be used to improve higher-order thinking skills; b) the use of android-based interactive physics mobile learning media (IPMLM) with an effective scaffolding learning approach in improving higher-order thinking skills. The effective contribution of the experimental group in increasing the ability of HOTS is 84.80%. The effective contribution of the control group that uses learning tools with the direct learning assisted by Physics textbooks in increasing HOTS ability is 55.50%.
The study objectives are to (1) produce an android-based Interactive Physics Mobile Learning Media (IPMLM) product in impulse and momentum material that is feasible to improve higher-order thinking skills (HOTS) of high school students; (2) know the effectiveness of android-based IPMLM in impulse and momentum material with a scaffolding approach toward HOTS of high school students. This research was Research and Development (R&D) with a 4D model. The development steps were: (1) Defining, including needs analysis activities; (2) Designing, the selection and design of research instruments and IPMLM activities; (4) Developing, an activity of developing research instruments and IPMLM, assessment of the feasibility of learning instruments, validation of research instruments, and assessment of the feasibility of IPMLM by experts, limited tests, and extensive tests; (4) Disseminating, an IPMLM dissemination activity. IPMLM feasibility assessment was carried out to determine the feasibility of IPMLM. Products that have been assessed by experts were further limited and extensively tested. The limited test subjects consisted of 13 students in the SMA Yayasan Pendidikan Kristen, Pontianak, while the extensive test subjects consisted of 48 students in SMA Koperasi Pontianak. The results show: (1) IPMLM is feasible to be used for enhancing students’ HOTS with “very feasible” criteria based on expert judgment; (2) IPMLM is effective for enhancing students' HOTS. The learning process assisted by IPMLM media with a scaffolding approach can help student complete tasks in the HOTS aspect and improve learning with 21st-century learning-based activities.
This paper studies the effect of scaffolding approach assisted by PhET simulation on the achievement of science process skills in physics. This paper used pre-experimental design with a one-shot case study. The sample of this study was students of class XI MIPA MAN 1 Yogyakarta. The sample consisted of 2 classes with the total of 57 students from the whole 3 classes selected by purposive sampling technique. The scaffolding approach in this paper consists of three levels, those are environmental provision, reviewing and restructuring, and developing conceptual thinking. The data was collected through observation of science process skills by using a checklist sheet. Aspects of science process skills which was observed included observing, formulating hypotheses, conducting experiments, interpreting, concluding, and communicating. The data analysis used descriptive analysis, calculation of the percentage of achievement of each aspect of science process skills, and calculation of the percentage of categories of achievement of science process skills. The results of the study show that the scaffolding approach assisted by the PhET simulation has a very good effect in physics learning for the achievement of the science process skills in physics.
Combination of Android-based IPMLM and scaffolding acts as a synergism that increase students' actual abilities towards their potential abilities (ZPD). Thus, it can bridge students to achieve HOTS. This study aimed to: a) produce an Android-based IPMLM with scaffolding learning approach in Newton's law of motion material that is feasible to apply to increase high school students' HOTS; b) examine the effectiveness of android-based IPMLM with scaffolding learning approach in Newton's law of motion material in increasing high school students' HOTS. This R&D used the 4-D model consisted of defining, designing, developing, and disseminating stages. Empirical test subjects of HOTS items were students of class XI MIPA, subjects of IPMLM readability test and extensive trial were students of class X MIPA. The extensive trial took two classes in each school, namely experimental and control class. Data collected through questionnaires and tests. Data analysis techniques included calculation of average scores, Aiken's validity index, item fit MNSQ INFIT-OUTFIT parameters, item reliability, and Anova mixed design test. The results showed that: 1) the developed Android-based IPMLM is feasible to be used in learning with scaffolding approach in Newton's law of motion material to increase high school students' HOTS; 2) The increase of HOTS in the experimental class is greater than the control class. Hence, an Android-based IPMLM with scaffolding learning approach is effective to increase high school students' HOTS, especially in Newton's law of motion material.
This study aims to find out know the effectiveness of learning using android-based IPMLM to improve psychomotor and self-efficacy of high school students. The research design uses Pretest-Posttest Control Group Design. The research subjects were 185 students of Class X MIPA from SMA N 1 Pakem, SMAN 2 Sleman, and MAN 3 Sleman and 210 students from class XI MIPA from SMAN 2 Kupang, SMAN 5 Kupang and SMAN 5 Kupang. Each school was taken two classes, namely the experimental class and the control class. Data collection instruments were selfefficacy questionnaires and psychomotor observation sheets checklist. Data were analyzed using descriptive statistics and inferential statistics. Descriptive statistical analysis was used to know the achievement of students' psychomotor and self-efficacy. The results showed that learning using Android-based IPMLM can improve students' psychomotor and self-efficacy. Psychomotor skills increased by 46.6% through learning using Android-based IPMLM. Meanwhile, the effective contribution of Android-based IPMLM to self-efficacy was 53%.
