This study aims to describe local wisdom on the island of Lombok that has the potential for ethnoscience to develop a learning model at Junior High School. This research uses a qualitative approach. The data collection method is done by using observation, interview, documentation, and literature study. The results showed that local wisdom on the island of Lombok that has the potential for ethnoscience is Sasak Sade Village, Bau Nyale Tradition, Sesek Weaving, Gendang Beleq, and Poteng Reket. Sasak Sade Village has a traditional house using certain sizes, namely length (Sedepa), width (Sesata), and height (Sprunjung). The Bau Nyale tradition is the hunting tradition of Nyale (sea worms). Sesek Weaving has various motifs and philosophies, various preparation processes, weaving and finishing processes to traditional waste utilization. Gendang Beleq is a traditional musical instrument made of animal skin and the two sides are closed, when it is hit the sound will bounce off the other side and go through a damping process so the resulting sound will sound smoother. Poteng Reket is a conventional biotechnology product. This local wisdom that has the potential for ethnoscience can be utilized in the development of learning models, especially in science subjects at Junior High School.
Abstract. It has been developed instruments of Causalitic Thinking Approach (CTA) in Physics learning to increase Problem Solving Ability (PSA) of pre-service teachers (low and high groups). Causalitic means causality and analitic. Implementation of the CTA at kinematics and Newton's law about movement increased the PSA of students (significance 5%) and the increases were not different between the low and high groups. PSA includes abilities of understanding (IPSA-1), selecting (IPSA-2), differentiating (IPSA-3), determining (IPSA-4), applying (IPSA-5), and identifying (IPSA-6). The differences between pre-test (initial PSA) and post-test (final PSA), and between PSA-gain of low and high groups were tested using Wilcoxon signed-ranks test. Pairs of tcounted and ttable (tcount, ttable) at IPSA-1 to IPSA-6 for low group were
Critical thinking has been a crucial competence in 21st century learning and encouraging critical thinking ability at the university level is assumed as an important achievement at higher education. This study was aimed at developing Reflective-Inquiry Learning (RIL) model to promote critical thinking ability for preservice teachers in particular. This study was a pre-developmental stage in which the developed RIL model was constructed in line with the supporting theories and empirical findings. With the result that, it produced a hypothetical framework from RIL model itself. Then, the product of the RIL model was validated with involving 7 experts as validators through a focus group discussion (FGD) process. The assessed aspect of the product consisted of the content validity and construct validity. The results of the product validity were analyzed through a descriptive analysis viewed from the average score of the validity. The result of the validity showed the validity level (Va) of the RIL model was 4.28 and it was said very valid. The conceptual framework of the developed model and the validity result would be further elaborated in this article.
This study aims to explore the effectiveness of Reflective-Inquiry Learning (RIL) model to improve the critical thinking ability of preservice-teachers viewed from cognitive style. Quasi-experimental research using one sample group was conducted in this study. The research sample consisted of 24 (twenty-four) preservice-teachers consisting of 14 (fourteen) males and 10 (ten) females. They are preservice-teachers (PTs) in the physics education study program – Universitas Pendidikan Mandalika (Undikma). Measurement of cognitive style using GEFT to classify the sample group into the field dependent (FD) and field independent (FI) cognitive style. Pre-test and post-test to measure the critical thinking ability of preservice-teachers. Data were analysed descriptively and statistically, where the n-gain test, normality test, and t-test (pair-t test) were conducted. The results of the study have shown that the RIL model is effective in improving the critical thinking ability of preservice-teachers in both the field dependent (FD) and field independent (FI) cognitive style. The results of further studies are described in this article.
This study aims to examine the effect of the problem-based learning model on students’ physics problem-solving abilities on work and energy materials. The type of research used a quasi-experimental research design with a nonequivalent control group design. The population of this study was students of class X SMA Negeri 1 Empang for the 2021/2022 Academic Year. The research sample was taken using the cluster random sampling technique so that 27 students of class X IPA 2 were selected as the experimental class and 26 students of class X IPA 4 were selected as the control class. The experimental class was given treatment in the form of learning using a problem-based learning model, while the control class used a conventional model. The instrument used to measure the problem-solving ability of students was a description test which is first tested for the validity, reliability, different capability, and difficulty of question level. The result obtained in the form of the average value of KPM obtained by the two classes in the pre-test was the experimental class of 15,48 and the control class of 13,38 and the average value of KPM obtained by the two classes in the post-test was the experimental class of 88,81 and the control class of 80,73. The result of the data analysis test showed that the pre-test and post-test data were homogeneous and the post-test data were normally distributed and the hypothesis test they were analyzed using the t-test in order to obtain the value of 3,15. The value at a significant level of 5% is 2,007, then the value is bigger then. Thus, it is concluded that there is a positive effect of the problem-based learning model on students' physics problem-solving ability in the matter of work and energy.
