This study aimed to investigate self-beliefs of 11th grade students in a mathematics PBL classroom (n = 47). The data were collected over a period of five weeks during the second semester of the 2018 academic year using students' self-construal questionnaires, students' self-efficacy questionnaires, students' observation forms, students'…

"Kurikulum Merdeka" is a learning experience framework that offers flexibility and focuses on essential content, character development, and students' competencies. Teachers had the discretion to develop their modules to choose, design, and organize the learning contents for students, based on their needs. By using that module, there is…

Students in Indonesia still have the low level of scientific argumentation skills. This study purposed to examine the impact of Problem-based Learning (PBL) with Argument Mapping and Online Laboratory in improving the scientific argumentation skill. It describes the significance of the differences between participants who learn through PBL, PBL…

A service learning course has been developed through which undergraduate science students create problem-based learning materials for use in high school science classes. Undergraduate students research active learning pedagogies with a specific focus on problem-based learning, create original materials to be used in grades 11 and 12 chemistry and…

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…

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,…

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…

How do scientists make inferences for something they cannot directly observe? The Black Box approach seems ideal to help students understand how scientists work. Black Boxes are sealed units; their interior is not accessible. The effort to determine their possible content (internal structure) demands successive modifications in hypothesis,…

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 meaningful learning of respiratory system will be enacted by students through the utilization of problem-based learning interactive media. This study aimed to develop problem-based interactive learning media on respiratory system material. This Research and Development (R&D) was conducted based on Borg and Gall with ten stages, namely: 1)…

One of the factors lead to the low critical thinking skill is the implementation of teacher center learning. The purpose of this research was to determine the effect of the implementation of Problem-based Learning integrated with Cooperative Script to students' critical thinking skills. This quasi-experimental research was done in senior high…

In this study, we explored the critical thinking of 47 eleventh-grade students in a mathematics problem-based learning (PBL) classroom in November 2016. A critical thinking test was used along with classroom observations to gather the critical thinking data in five dimensions according to the Association of American Colleges & Universities…

Traditionally, cognitive skills in mathematics and language have been described as key indicators for success. However, the social, technological, and economic changes that have occurred in the 21st century have made critical thinking, creativity, communication, and collaboration, key competences to face the challenges of a rapidly changing world.…

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…
