This paper explores the spatial dimension of Fleming's Left Hand Rule (LHR), commonly-used in Physics instruction for determining the direction of force using the left hand's thumb, forefinger and middle finger. A new instrument was developed to gauge students' ability to coordinate their fingers in 3D space (egocentric frame of reference) based…

Critical thinking (CT) is a type of convergent thinking explored when students learn mathematics. This study aims to obtain a comprehensive representation of students' mathematical Critical Thinking (CT) abilities, based on the mathematical ability level. Data were obtained from 35 students using CT skills tests and semi-structured in-depth…

If using different instruments obtained a different analogical reasoning component. With use people-piece analogies, verbal analogies, and geometric analogies, have analogical reasoning component consists of encoding, inferring, mapping, and application. Meanwhile, with use analogical problems (algebra, source problem and target problem is equal),…

Evidences showed that students' chemistry learning outcomes were still low. One of the causes was the chemistry practicums carried out so far were traditional chemistry practicums. Therefore, it needed to be reoriented towards the practicum. Thus, this study aimed to investigate the effect of green chemistry practicums on students' learning…

This study introduces a small-scale chemistry practicum technique with the concept of acid-base identification, determination of pH with indicators, and neutralization reactions with the concept of titration. The first experiences of teachers and students in small-scale chemistry practicums are revealed. Action research was carried out to…

The magnetic field is a more complex and abstract physics subject than other physics subjects, causing students' low ability to solve problems. So there is a need for learning instruments to overcome these problems, especially when online learning during the COVID-19 pandemic. Research creates and implements an online problem-based learning (OPBL)…

This research development is motivated by low learning outcomes Art Culture students of class XI software engineering 1 SMK Negeri 14 Medan. This study aims to (1) describe the design of blended learning development, (2) to describe the validity of the blended learning development result, and (3) to know the effectiveness of the use of blended…

This study targets to 1) describe students' mathematical reasoning skills in terms of guardian personality type; 2) knowing the causes of student mistakes in answering questions. This type of study is descriptive qualitative. The subjects in this study were students of class XI MIPA four Wanasaba 1 Senior High School in East Lombok in the…

This study aimed at determining the category and analyzes the mental models of the students from three senior high school clusters (low, medium, high) on the solubility and solubility product topic, knowing students' opinions on chemistry subject, knowing learning methods and assessment that teacher used in solubility and solubility products…

This research aims to determine whether there is an influence of applying the Problem Based Learning (PBL) Model with the Technological, Pedagogical, and Content Knowledge (TPACK) Approach on the historical learning outcomes of high school students of Sultan Iskandar Muda Medan. This study uses a quasiexperiment research method. The population in…

Students' scientific thinking skills can be empowered by implementing certain learning models in which they are given opportunities to perform some scientific activities. This study aims at investigating: (1) effect of guided inquiry learning model on scientific thinking skills; (2) effect of different types of scientific activities on scientific…

Indonesia's geographical positioning along the 'Ring of Fire' exposes it to frequent seismic activities, making effective disaster mitigation education crucial. Current educational strategies may not adequately foster the necessary empathy and understanding among students regarding the socio-environmental impacts of disasters. This study aims to…

The mathematical reasoning ability is one of the essential hard skills of a student, especially in solving everyday problems. In supporting the achievement of this mathematical reasoning ability, meaningful teaching materials are an essential part of keeping exciting and not dull a learning process. This study aimed to design and develop an…

The excretory system should be taught through constructivism so as conceptual understanding could be built well, and students could apply their knowledge in daily life. The research aims to find out the influence of a learning model of Cooperative Integrated Reading and Composition (CIRC) based on scientific approach (Cirsa) on conceptual…

The goal of this research is to determine whether the Role Play Technique may improve students' speaking skills, particularly in grade XI. The study was carried out at SMAN 1 Cisarua, Bandung Barat, with 34 students from grade XI Science-3 serving as the sample. This is a pre-experimental study. After 16 hours of treatment (two hours per meeting…
