Although existing literature suggests that teachers perceive, mobilize, and leverage resources to support ambitious instruction, less is known about how teachers and students jointly take up resources for co-constructing scientific knowledge. This study examines how teachers and students utilize aspects of practice-oriented curriculum materials…

In the digital age in which we live, one of the primary goals of education is to nurture individuals who are capable of thinking creatively, solving problems, and being innovative and productive. Computational thinking is an analytical process that requires defining problems and at the same time solving these problems by proceeding in creative…

This study aims to investigate the effect of the problem-based learning method supported by experiments on the inquiry learning skills of secondary school students and their reflective thinking skills for problem-solving. This research uses a quasi-experimental design with a pretest-posttest control group. This study consists of 21 students in the…

Given the current emphasis on science, technology, engineering, and math (STEM) education and its key attributes, middle school is an optimal time to implement STEM-based curricula. However, the interdisciplinary and open-ended nature of STEM projects often makes implementation difficult. In this article, we describe a professional development…

Decision matrices are valuable engineering tools. They allow engineers to objectively examine solution options. Decision matrices can be incorporated in K-12 classrooms to support authentic engineering instruction. In this article we provide examples of how decision matrices have been incorporated into 6th and 7th grade classrooms as part of an…

This study aims to develop an electronic library-based learning environment to support teachers in developing web-based problem-solving activities and analyzing the online problem-solving behaviors of students. Two experiments were performed in this study. In study 1, an experiment on 103 elementary and high school teachers (the learning activity…

This study proposes an empirical classification of ways to introduce elements of the history of science into science teaching, as well as describing a special way to do so characterized by the introduction of short extracts from historical texts. The aim is to motivate students to participate in problem-solving activities and to transform their…

Lunar Nautics is a hands-on curriculum targeted to youth in grades 6 to 8, that allows the students to design, test, analyze and manage a space mission from initial concept to project funding. Lunar Nautics provides opportunities for development of problem solving skills and critical thinking skills that are needed to design, organize and manage a…
