Critical thinking skills are among the main skills in the 21st Century. However, many schools in Indonesia have not trained their students' critical thinking skills optimally. The purpose of this study was to identify the quality of high-school students' critical thinking skills. A survey was conducted to 175 tenth graders who were registered in…

The instructional models that have been implemented in the classroom could not support the development of students' critical thinking skills. These instructional models can be well implemented if those models can facilitate students with meaningful learning experiences such as reading, connecting prior knowledge to new information being learned in…

Research on active learning that emphasises question formulation activities has received less attention. This study was conducted to address the said gap identified in the literature by testing the thinking empowerment by questioning (TEQ) strategy on the level of conceptual understanding (CK) and critical thinking (CT) of students in Biology…

Questions serve as an element that can be used to access and stimulate students' thinking ability. This research aimed at analyzing the students' ability to pose Higher-Order Thinking Skills (HOTS) questions during the learning process. This research was a survey research using a descriptive quantitative approach. The samples used in the research…

The empowerment of metacognitive skills has an important role in increasing the capacity of critical thinking and active control of students' cognitive processes in learning. Metacognitive skills can be enhanced through the implementation of learning strategies involving higher-order thinking. The RQA, ADI, RQA integrated with ADI are…

The present study was an attempt to investigate the effect of Problem-Based Learning (PBL), Predict, Observe, Explain (POE), and the combination of both (PBLPOE) on students' critical thinking skills and scientific attitudes in Biology. A pretest-posttest nonequivalent control group design was employed in this study and 132 tenth-grade students…

This study aimed to investigate the differences between: 1) low-ability students' critical thinking skills and high-ability students' critical thinking skills, 2) male students' critical thinking skills and female students' critical thinking skills. This research was a survey conducted in some public Senior High Schools (SMAs) in Batu, East Java,…

In inquiry-based learning, teachers usually only apply one level of inquiry from the four available levels. The diversity of students should be a serious consideration. Differentiated Learning Science Inquiry (DSI) implements the four levels of inquiry. To train students' creative thinking, inquiry can be integrated with mind maps. This research…

The purpose of this study was to investigate the effect of RICOSRE learning models towards critical thinking skills of students with different academic abilities. This quasi-experimental study employed a pretest-posttest nonequivalent control group design and involved all the eleventh-grade students from high schools in Malang, Indonesia. The…

The aim of this research was to reveal the relationship between student's reading interest and critical thinking skills through Reading Concept Map Group Investigation (Remap GI) and Reading Concept Map Jigsaw (Remap Jigsaw) learning models. To do so, two science classes from first grade of two Senior High Schools in Malang, Indonesia were…

Some research findings showed that Indonesian students' critical thinking skills below average, especially those who have a low academic ability; even though that skills are needed to face this 21st century. There should be a strategy to train students to develop their critical thinking, one of them is by implementing an appropriate learning…

Students' critical thinking skills are very important in the 21st century. Learning strategies can play a role in enhancing students' critical thinking skills in the Nutrition and Health lecture. The results of a survey in 2013 showed that the implementation of learning strategies had not given students the opportunity to practice their critical…

The aims of this study were (1) to find out the differences in critical thinking skills among students who were given three different learning models: differentiated science inquiry combined with mind map, differentiated science inquiry model, and conventional model, (2) to find out the differences of critical thinking skills among male and female…

This research was carried out to analyze the effectiveness of the Search Solve Create and Share learning integrated with metakognitive strategy [SSCS + MS] on the creative thinking ability of low academic students. A quasi experimental design has been used to compare the effect of traditional learning, SSCS, and SCCS + MS learning on the creative…

Previous studies in Malang, Indonesia, showed that there were the failure biology learning caused by not only the low students' prior knowledge, but also biology learning model has not improved the students' critical thinking skills yet, which affected the low of cognitive learning outcomes. The learning model is required to improve students'…
