Making predictions and observations, interpreting data, and drawing conclusions are all examples of scientific problem-solving procedures. The purpose of this research was 1) to develop scientific problem-solving skills by applying problem-based learning as a basis for students in grade 9 to pass the 70 percent requirement and 2) to study the…

Students need critical thinking skills to develop their ideas in mathematics learning situations at school, and they can apply mathematical concepts in solving contextual problems. Junior high school students have unique characteristics and are highly curious about new knowledge. Therefore, it is crucial to apply the learning models that support…

An analysis of critical thinking research during 2010 to 2021 was conducted using effect size criteria; subsequently, a model was proposed for teaching and learning management that promoted critical thinking by students at the basic education level using the Thai digital collection data base. Based on a search of past research quality examination…

This research explores the impact of integrating smart water monitoring with internet of things (IoT) into 7th-grade science education using the problem-based learning (PBL) model. A quasi-experimental research design with a post-test-only control group is employed to compare the effectiveness of two learning groups: one using the regular PBL…

This research aimed to explore the effect of problem-based STEM activities on middle school students' perceptions related to problem-solving skills and their critical thinking tendencies. The sample consisted of 81 students. A mixed method was employed in the research. The quantitative data collection tools were the "Critical Thinking…

The importance of literacy is a competency requirement that must be possessed by students to face competition in the 21st century. This is directly related to the extent to which students' scientific thinking processes understand and solve problems. This study aims to describe how literacy is trained in learning in junior high schools. The…

Amid the maker movement, educators are proposing various making activities with programmable artifacts to prepare students for coping with the challenges in the twenty-first century. Today, the "4C" skills--critical thinking, creativity, communication, and collaboration--are regarded as significant learning outcomes in Science,…

Previous research found that critical thinking skills of students need to be trained more intensively using authentic problems in daily life. Critical thinking can be developed through problem-based learning as a pedagogical approach in an aligned learning and teaching context. This research aims to obtain the profile of students' critical…

Problem-based learning (PBL) is a pedagogy where students gain knowledge about a subject through solving an ill-structured problem. Critical thinking skills (CTS) are the capacity to think about what to do or what to consider by an individual. This study sought to decide if using Problem-based Learning (PBL) improves the critical thinking skills…

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…

In this study, an obstacle unlikely faced by teachers is the lack of innovation in the learning model employed. The teachers are still being the center of learning resources so that they are made to correct the perception by creating a learning model that students prefer. This study aims to provide a new design in environment-based-learning (EBL)…

The aim of this study was to determine the relationship between students' metacognitive learning, critical thinking, scientific process skills, and academic achievements after the "Cell and Divisions" and "Force and Energy" units which have been processed according to different teaching methods. Furthermore, in this study, it…

This study aims to determine the effect of applying problem based learning model on students' mathematics learning outcomes viewed from critical thinking skills of fifth grade students of the private primary school in the Surakarta region. This research is an experimental research using sample of 309 students consisting of experimental class of…

Teachers constantly struggle to get students actively engaged and invested in their own learning. It can be even more difficult to engage those students in critical thinking and 21st century skills. Problem-based learning (PBL) provides a student-led format with real-life learning experiences, offering a purpose for instruction. By relinquishing…

This research was conducted to evaluate the effects of Problem-based Learning (PBL) with Thinking Maps (TM) teaching method (PBL-TM) on Fifth Graders' science critical thinking. The critical thinking skills evaluated were Comparing and Contrasting, Sequencing, and Identifying Cause and Effect in physical science. A quasi-experimental pre-test and…
