The construction of a concept can be developed from the students' prior knowledge. Regarding deaf students, it is considered their conceptions conceived through vision. Given this, the present research was conducted with a group of deaf students in the 7th year of elementary school with the aim of verifying what ideas these students had about…

Engagement with socioscientific issues (SSI) has emerged as an important focus for science education. SSI have been successfully used to teach science concepts, but they also serve a role in helping learners develop a capacity to engage with science in everyday life. Here we present an epistemic framework for characterizing socioscientific…

Big ideas in science education are meant to be interpretive frameworks that empower student learning. Unfortunately, outside of the broad conception of scientific evaluation, there are few theoretical explanations of how this might happen. Therefore, we contribute one such explanation, an instructional concept called integrative analysis wherein…

This study evaluates the experimental tasks of the Ethiopian grade 12 chemistry textbook vis-à-vis coverage of the essential components of science process skills (SPSs) using content analysis. All the procedures in an experiment were analyzed using rubrics of the inquiry-based task analysis inventory (ITAI) instrument. This instrument was based on…

In this study, we investigated the construction of science learning opportunities focusing on space-time relationships. Guided by ethnography in education, we followed the everyday life of a classroom over their three first years at elementary school. Based on macroanalysis, we examined discursive interactions in temporally distant events and how…

Worldwide, education jurisdictions are looking for authentic ways to address First Nations perspectives in the K-12 curriculum, including science education. At the same time, there have been ongoing efforts to integrate authentic and engaging approaches to teaching science, including those that are student-centred, inquiry-based, multimodal, and…

This study seeks to determine whether giving an explicit incentive to students in an upper-division first-semester electromagnetism course (EM1), in the form of partial credit for reworking unit exam problems, will improve their problem-solving skills as measured by performance on identical problems on the final exam. Three problems--a primarily…

This study aims to determine the effectiveness of the author's teaching technology in developing schoolchildren's research skills, the challenges an elementary school faces, and how the entire process of developing research skills works. Quantitative and qualitative research techniques were used. Participants were from No.15, No.1, No.46, and…

Modeling is a fundamental tool in the teaching and learning processes of life and earth sciences. It serves as an investigative instrument that enables students to test hypotheses and solve scientific problems. This paper presents the findings of a survey conducted among 96 Moroccan life and earth sciences teachers teaching students at the…

The aim of this study was to investigate the perspectives of science teachers who are pursuing postgraduate studies on their experiences in preparing a research project and to explore the effects of this experience on the participants. In this context, a qualitative research method was employed using an action research design. Seven science…

This study aimed to explore Cooperative Learning theories and practice by examining the relationships among three aspects: Experience, Practice and Perceptions. The data were from interview records from eight science teachers. As a student-centered active pedagogical trend, cooperative learning has become part of one of the most effective and…

This dissertation focused on the outcome of elementary science teachers' learning in theories and practices of epistemic tools in professional workshops over the course of two years, starting in the summer of 2019. Study one focuses on teachers' understanding of language as an epistemic tool. The data were teachers' written responses to a…

In this study, I documented, analyzed, and compared the thought processes of six high school science teachers during twenty minutes of planning for NGSS-aligned instruction. Teachers' thoughts were captured using a virtual revisit think-aloud protocol and their thoughts were analyzed and compared using a novel tool called a thinking web. A…

Recently, smart sensing/actuation paper has attracted significant interest due to its potential usage as a sustainable component in future electronics, robotics, and intelligent sensing devices. In acknowledging the importance of this topic for the engagement of students at the university level in conjunction with Industrial Revolution 4.0, it is…

This manuscript describes a laboratory exercise that allows students to use conductive atomic force microscopy (CAFM) for the analysis of electrodeposited, metallic structures. In addition to nanoscale electrical characterization with CAFM, this laboratory exercise also provides students with an opportunity to explore nanofabrication by…
