Asking Questions

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.

Materials Used

This study aims to analyse textbooks used by students based on the scientific approach as the realization of learning objectives using the 2013 curriculum. This study did several things: first, an investigation of the teaching materials used by students based on the scientific approach, second studied the suitability of the content of textbooks used by students with the syllabus in the 2013 curriculum, thirdly investigating the contribution of textbooks used to higher-order thinking skills. Research method used is mixed methods namely descriptive method and survey study at Islamic Junior High School in Medan. There are 3 textbooks that will be analysed, the textbooks from three different publishers which used by the school. The total number of students who participated in this study were 201 students. Where students who participated in the study were selected based on purposive random sampling through certain considerations, the students come from Islamic Junior High School An Nizam, Islamic Junior High School Ulun Nuha, and Islamic Junior High School Al Fityan, the condition and character of schools are almost same, so is expected the homogeneous sample. The results obtained are: (1) From the three books, the results of conformity assessment with the syllabus in book A are 65%, book B is 80%, and book C 40%; (2) The evaluation results of the textbooks by using the scientific steps find that book A obtained a score of 53 in the low category, book B got a score of 58 in the low category, and book C got a score of 55 also in the low category; 3) The results of the assessment of HOTS ability of students from each school that use books A, B, and C are on the average low category.
