Scientific reasoning, argumentation, and problem-solving are essential skills in 21st century. They help people solve problems in daily life. This study aimed to investigate the effect of local-based teaching materials on student's argumentation, scientific reasoning, and problemsolving skills using Science Project-based Learning (SPjBL).…

Real Engagement in Active Problem Solving (REAPS) cultivates exceptional talent across disciplines through students solving problems that are real in their lives. In this study, the focus was on scientific talent: to determine students' growth in creative problem solving in science in classrooms in which REAPS was implemented. Using a repeated…

A revised version of a traditional physical chemistry laboratory experiment has been developed to enhance student discussion in the laboratory and to improve students' connections between physical chemistry concepts and real molecular systems. In this experiment, students explore the keto-enol tautomerization of 2,4-pentanedione. However, unlike…

The ability of students to perform quantitative analysis is a fundamental aspect of analytical chemistry courses and laboratories. In this laboratory experiment, students quantitatively analyze both liquid and solid samples through the use of internal standard calibration and ATR-FTIR spectroscopy. Using a problem-based approach to selecting their…

The presented research focuses on verifying the confluent application of concept mapping (CM) and socio-scientific issues (SSI) according to the value-laden and moral dilemma orientation to construct problem-solving performance. This research sets up some perspectives for all 146 participants, including 139 students and 7 experts. All findings…

This study investigates if collaboration and the level of heterogeneity between collaborating partners' problem-solving scripts can influence the extent to which pre-service teachers engage in evidence-based reasoning when analyzing and solving pedagogical problem cases. We operationalized evidence-based reasoning through its content and process…

Imagination is necessary for scientific practice, yet there are no in vivo sociological studies on the ways that imagination is taught, thought of, or evaluated by scientists. This article begins to remedy this by presenting the results of a qualitative study performed on two systems biology laboratories. I found that the more advanced a…

Reasoning about organic chemistry reaction mechanisms requires engagement with multiple concepts and necessitates balancing the relative influence of different chemical properties. A goal of organic chemistry instruction is to support students with engaging in this type of reasoning. In this study, we describe our use of case comparison problems…

This paper is about an experimental problem on forced oscillations, which was given to 14-year-old primary school pupils at the Slovenian national (final) level of the physics competition in April 2019. At the time when the competition took place these pupils were approaching the end of the school year, when they encountered physics as a school…

Written instructions seldom need to be read when playing videogames. Instead, gaming often involves early information foraging and expansive exploration behaviors. We use data from the Programme for International Student Assessment (PISA) to explore whether students who regularly play videogames (daily gamers) adopt behaviors that are typical of…

Scientific thinking is considered as a cognitive process in which the underlying causes of a basic problem are solved. It is of great importance for teachers to have scientific thinking skills to improve their professional lives, to create effective learning environments, to continuously question the events and processes in the classroom, to carry…

As a "wicked problem," climate change requires interdisciplinary understanding and collaboration in order to prepare future leaders to develop solutions. To this end, as an ecologist and an anthropologist at a mid-sized university in the southeastern U.S., we designed a pair of interdisciplinary, research-intensive courses for first-year…

The purpose of this research is to examine the impact of activities based on scientific process skills on problem-solving skills of 4th grade students in science lessons. In the study a non-equivalent control group pre-test and post-test design type of quasi-experimental method was used. The research study group was composed of 30 students with 15…

This study used three previously validated instruments, namely Science Academic Hardiness (SAH), Students' Conceptions of Learning Science (COLS) and Science Learning Self-Efficacy (SLSE) on 431 Singaporean students. Using structural equation modeling, results showed that the SAH commitment dimension a positive predictor explaining both the…

This study was carried out to examine the relationship between secondary school students' problem-solving skills and scientific attitudes in terms of gender, class level and education level of the parents. In the study, correlational research model, which is among the general survey models, was employed. The sample of the study consisted of 560…
