This study aims to develop thermal length expansion practicum sets that are expected to improve high-school science process skills (SPS) in expansion material on metal rods. This research was conducted at SMAN 2 Bekasi in class XI by comparing the control and the experimental class. This study uses the ADDIE approach to analyze, design, develop, implement, and evaluate the thermal expansion length practicum sets. The feasibility test of this practicum sets was carried out in two ways: conducting experiments and validating tests from experts. The experimental results for the linear expansion coefficient of an iron bar are 3.09%, the brass is 5.81%, and the aluminum is 7.39% from the reference value. All of the experimental data still below the error acceptance level which is below 10%. The validation results give 85.5% from media experts and 86.1% from material experts. The trials on users obtained 93.9% of teachers and 85.4% of students. The N-gain in control and experiment class then compared to see the increase in SPS in each category. There was an increase in the experimental class SPS value 7.3% higher than the control class, where the SPS value in the experimental class increased by 47.8%. Therefore, it can conclude that the thermal expansion practicum sets is feasible to use and can improve the science process skills of high school students.

The study aims to evaluate the effectiveness of an inquiry-based virtual reality (VR) science lab used in junior high school science classes. The Scientific Investigation VR Lab (SIVRLAB) is designed for 9th-grade students to learn about electrochemical cells. It is situated in a guided problem-solving context, where learners need to review the concept of oxidation-reduction reactions and assemble a voltaic cell to save a robot. The SIVRLAB features several cognitive supports and guides for students to plan and record experiments and resolve the problem. It has both a head-mounted display (HMD) version and a desktop VR version. The study recruited 66 9th graders from three classes to evaluate the two versions of the SIVRLAB. The students were assigned to one of three conditions, namely, (1) using immersive HMD SIVRLAB individually, (2) using desktop SIVRLAB individually, and (3) observing one student use immersive HMD SIVRLAB. The students were briefly introduced to the concept of electrochemical cells in the first class and were instructed to use the SIVRLAB sessions in the next class. The results from knowledge pre- and post-tests, a user experience survey, and students’ reflections were collected and analyzed qualitatively. The findings revealed that students who used the desktop VR obtained the highest test scores among the three groups. However, in the follow-up physical laboratory test, the performance of the students in the original HMD VR experimental group was better than those in the desktop VR experimental group. The paper also discusses student feedback and teacher observations regarding the design and interaction with immersive VR. Lastly, the implications of the study and recommendations for future studies are presented.

Peserta workshop sangat antusias selama mengikuti kegiatan dan merasa sangat terbantu dalam mengatasi kendala dan permasalahan yang dialami guru-guru IPA di sekolah masing-masing. Perlu perluasan peserta workshop di berbagai daerah agar mampu meningkatkan peran laboratorium dalam mendukung tujuan pembelajaran IPA yang meliputi pengetahuan, sikap dan keterampilan ilmiah peserta didik.The laboratory has a very important function as a means of science learning to facilitate students to build their scientific competences. Therefore, we need proper management which is performed by the competent laboratory managers. This workshop was conducted to strengthen the teachers’ competence in optimizing the functions of a science laboratory. The workshop methods including lectures, discussions, inquiry-based laboratory practices and implementation of school’s laboratory management. The participants were 19 junior high school science teachers in Banjarmasin City and Banjar Regency. This workshop was able to strengthen teachers’ knowledge and skills in mining school’s laboratory, teachers’ skills to design and implement guided inquiry-based practicum, and teachers’ ability to apply skills in managing science laboratory. The participants appear very enthusiastic during the workshop and they felt greatly helped in overcoming many laboratory obstacles and problems. It is necessary to expand the workshop’s participants in various regions in order to increase the role of laboratories in supporting science learning objectives which include scientific knowledge, attitudes, and skills of students.
