Drawing inference from data is an important skill for students to understand their everyday life, so that the sampling distribution as a central topic in statistical inference is necessary to be learned by the students. However, little is known about how to teach the topic for high school students, especially in Indonesian context. Therefore, the…

This research aimed to describe and find out whether implementation of Problem-Based Learning can improve scientific explanation skills in biology learning about the environment. The research method was Classroom Action Research through the implementation of Problem-Based Learning. This classroom action research consisted of two cycles, which were…

This study aims to find improvements in the quality of the process and learning outcomes of sociology through problem-based learning modeling integrated with Islamic values and empirical research in madrasas. This study uses a class action research development approach. The research subjects were 32 students of class XII in an Islamic school. Each…

Due to the COVID-19 pandemic, learning activities have encountered obstacles. One of the impacts was the low learning outcomes achieved by students. The purpose of this study was to improve the learning outcomes of junior high school students during the physical distancing period by implementing problem-based learning through Smart Apps Creator 3.…

The 21st-Century learning has been widely associated with problem-solving skills in a global perspective but not much related to local wisdom, even though local perspectives are also needed in adapting people's daily social lives. The purpose of this research was to analyze the effectiveness of Enculturation-Assimilation-Acculturation (EAA) model…

Environmental conservation understanding is one of the crucial factors which determines student attitudes and behavior towards the environment. This study aimed to investigate the effects of problem-based learning and naturalist intelligence on the students' understanding of environmental conservation. This experimental research was conducted at…

The previous research result showed that the learning model based on the investigation could increase the students' critical thinking skills. The aim of this research was to measure the effectiveness of the using of problem-based learning model to increase the students' critical thinking skills. The research design was quasi-experiment by using…

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,…

Since Indonesian students' critical thinking skills in junior high school is still in unexpected level, it should be improved through teaching and learning process. The objective of the study is finding out the influence of problem centered learning approach toward students' mathematical critical thinking ability. Every student should have…

Problem-Based Learning (PBL) is a constructivist learning with the potential to enhance students' science process skill. The implementation of PBL has revealed many advantages, however, a free exploration from a highly complex environment may result in a heavier workload of memory. Accordingly, practicum method can be used to overcome the…

This study aimed at investigating the impact of problem-based learning (PBL) on students' writing skills and the process of teaching and learning. An embedded mixed-method design was applied involving 41 seventh grade students of SMP Negeri 4 Denpasar. In this study, the quantitative data were students' writing skills which were collected through…

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…

Purpose: This study aimed to investigate the potential effects of problem-based learning (PBL), predict observe explain (POE), and PBLPOE on students' problem-solving skills and self-efficacy in Biology. This research is based on various facts that problem-solving skills and self-efficacy of Indonesian students in biology subjects are still low.…

One of the important affective factors for students in mathematics learning is self-efficacy. The students should have high mathematics self-efficacy. So, it can support the success of learning process. The facts that indicated the low of students' mathematics self-efficacy, encouraging the efforts to improve self-efficacy through the improvement…

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…
