This research aimed to reveal the effectiveness of using a Problem-Based Learning (PBL) physics pocketbook integrating augmented reality (AR) with the local wisdom of catapults in improving the mathematical and graphical representation abilities of high school students. This study is a quasi-experiment with a pretest-posttest control group design.…

Implementing a proper learning model during the post COVID-19 pandemic is fundamental for learning quality enhancement, specifically for students' conceptual mastery. The research aims to develop a Complexity Science-Problem Based Learning (CS-PBL) model assisted by the "Sistem Informasi Pengelola Pembelajaran" (SIPEJAR) e-learning…

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)…

The limited time allocation for lectures in the classroom is an obstacle to presenting student-centered learning. This is one of the factors that prospective physics teacher students experience conceptual difficulties, especially in crystal structure material. So the purpose of this study was to determine the effectiveness of the problem flipped…

Regarding 21st-century learning, scientific literacy is an important competency which must be owned by students. Nevertheless, scientific literacy of Indonesian students has been recognized in low level. This study aimed to describe students' scientific literacy in Bryophyta topic using problem-based learning. This Classroom Action Research (CAR)…

This paper tells about the mental model of prospective scholars on the topic of temperature and heat. The purpose of this research is to improve students' mental model by using problem based learning (PBL) model. The number of samples in the study amounted to 72 students with two different classes. The results of the study showed that, (1) the…

The research mixed method aims to investigate students' creative thinking skills about elasticity in physics. The students' creative thinking skills were measured by diagnostic tests developed by researchers and validated by theoretical physics. The instrument included several indicators of critical thinking skills including fluency, flexibility,…

A mental model (MM) is an internal representation of students' conceptual understanding. Currently, students have still had difficulties in explaining the physical state of elasticity of solid materials, at submicroscopic level. These difficulties call for this research. Through a mixed method, the study aimed to reveal the development and…

Students difficulty in relating chemistry concepts to everyday life leads to their inability to explore and developed skills needed, especially critical thinking. Therefore, this study aimed to develop students' critical thinking skills by integrating socio-critical and problem-oriented approaches to chemistry learning with environmental issues in…

The objectives of the research were to identify the difficulty level of various types of chemical representation for students and to examine the effects of two different models of teaching and learning chemistry (problem-solving based on multiple representations and problem-solving) on the students' cognitive achievement in chemical equilibrium.…

This study aims to determine the influence of learning models and numerical ability of students' chemistry learning outcomes on Thermochemical materials, as well as the interaction between learning models through the use of laboratory and numerical ability. The study was conducted on the students of grade XI IPA SMA N 1 Stabat consisting of 9…
