This study aims to describe the 3D model's online modules effectiveness in the practicing mastery of conceptual knowledge in solar system learning using an instrument which tested 58 7th-grade respondents from one of the junior high schools in Jombang, East Java, Indonesia. The respondents were then divided without randomization into 29…

Research on active learning that emphasises question formulation activities has received less attention. This study was conducted to address the said gap identified in the literature by testing the thinking empowerment by questioning (TEQ) strategy on the level of conceptual understanding (CK) and critical thinking (CT) of students in Biology…

The purpose of this research is to see what physics misconceptions students have regarding heat material. This study employs a three-tier diagnostic exam designed to identify students' physics misunderstandings. 150 grade VII students from five Lamongan district state junior high schools were included in the study. Creating a closed-ended the…

The students' explaining skill is interrelated with their conceptual understanding. This study aimed to determine the effect of the implementation of the student facilitator and explaining model assisted by the media game on the students' explaining skills related to environmental pollution. This quasi-experimental research was using a pre-test…

A practicum is beneficial in science learning to provide a concrete manifestation of a topic. This study aimed at creating a simulation-based interactive learning multimedia product to assist students' practicum. The product was developed for the topic of cell metabolism process focusing on the energy in living systems. The study employed the…

Most junior high school students considered chemistry as a complicated science subject with an abstract concept, symbols, and terms that must be memorized. The difficulty of learning chemistry made students had low positive perceptions of chemistry. It was needed the right ways to introduce chemistry to them. The purpose of the multiple case study…

There is growing interest in the introduction of Einsteinian concepts of space, time, light and gravity across the entire school curriculum. We have developed an educational programme named 'Einstein-First', which focuses on teaching Einsteinian concepts by using simple models and analogies. To test the effectiveness of these models and analogies…

Among three levels of chemical representation, the sub-microscopic level is the most difficult to learn by students. To solve the problem, it is assumed that the concept of the discontinuous nature of matter or particle concept should be mastered initially by students before they learn sub-microscopic representations of further chemical phenomena.…

An efficient way to improve the quality of education in critical thinking is developing the better tests. The test has been shifted towards the use of computer-based procedures. Lack of specific topic of critical thinking tests in science and the advanced of technology made the researcher intended to develop and validate a test to measure…

This study investigated the impact of the problem-solving model on students' concept mastery and motivation in learning heat based on gender. The method which was used in this research was quasi-experiment with pretest-posttest design in girls and boys class. Data are collected from girl class (N=16) and boys class (N=16) of a 7th grade in one of…

In designing the lesson teachers have to adapt the method or learning model with the material to be taught. In the teaching of measuring concept, students frequently faced with measuring instruments, micrometer, screw, scale, and so on. Direct Instruction Model would be suitable for teaching the measurement concepts specifically the skill of using…
