This study aims (a) to determine the effect of synectics model on creative thinking skill (b) to determine the effect of synectics model on metacognition skill. (c) to find out the relationship between creative thinking and metacognition skills. This study uses a quasi-experimental type with one group pretest posttest design. The study population…

This study aimed to investigate the effect of online problem posing on students' problem-solving ability in mathematics. The study followed a quasi-experimental research with post-test that only controlled group design. The population was all of the 11th grade students in science classes of SMA Negeri 4 Singaraja in the academic year 2017/2018. A…

Chemistry learning in high school should encourage the application of knowledge learned to solve real-world problems around students without delay. This study aimed at analyzing the effect of the project based e-learning model (PjBeL) compared to direct e-learning (DeL) and academic procrastination (AP) on students' critical thinking skills and…

This qualitative study aimed at describing student verbal interaction verbally through cognitive activities consisting of procedural, disputational, and exploration in solving geometry problems. This research was in the form of students' verbal interaction activities in group discussion which decribe students' thinking process in detail, both 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…

The research aimed to produce an Android-based learning media with local cultural content in the form of the othok-othok toy ship to improve the competence of diagrammatic and argumentative representation in Physics. 4D methods were used with a control and an experimental class in the first grade of a Senior High School. The learning media…

This paper reports the findings of a quasi-experiment that aims to investigate the role of metacognitive teaching-learning (MTL) and mathematical prior knowledge (MPK) on students' mathematical logical thinking ability (MLTA) and self-regulated learning (SRL).
