The aims of developing classroom based assessment for science teacher at secondary school in Koto Tangah district are enhancing the science teacher’s competency and strengthening the principle of developing classroom based assessment. Participants are consisted of 35 junior high school science teacher in Koto Tangah district. Training and workshop method were used in this program to accomplish the goals. Before implementing the program, participants were given a prior knowledge about the basic rules of classroom based assessment. In addition, participants were given the instruction sheets to arrange the classroom based assessment and exercising to develop it with instructor’s guidance.

The purpose of this developmental research was to develop a scientific approach based science worksheet on the dynamic electrical material topic for ninth-grade junior high school students.  The worksheet were developed based on scientific approach. The stages include:  observing, asking questions, gathering information, processing information, and communicating. The development model used is the 4-D Model consists of 4 stages: define,  design, develop, and desimanate. The results of the validation, a small and large group trials indicated that the used of the scientific approach based science worksheet was appropriate for use. Thus, the developed worksheets can be used in the process of learning for Junior high school science students. Keywords : Worksheet , Scientific approach

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.
