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…

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…

This study highlights the importance of incorporating modern mass spectrometry techniques into undergraduate education. By focusing on the structure-characterizing capability of MS, students are able to gain hands-on experience with cutting-edge techniques and better understand how MS can be used to solve real-world problems. The three-step lipid…

Thin-layer chromatography, which involves the movement of dyes along a silica-coated plate, is used to observe the progress of chemical reactions and to separate mixtures. We took advantage of this phenomenon to devise a method for generating patterns in the shape of numbers with dots (dot matrix). We prepared the azo dyes necessary for generating…

In this laboratory teaching experiment, commercial cannabis oils were analyzed by undergraduate organic chemistry students using gas chromatography-mass spectrometry (GC-MS) to investigate three isomeric cannabinoids commonly found in cannabis products: cannabidiol (CBD), [delta][superscript 9]-tetrahydrocannabinol ([delta][superscript 9]-THC),…

Understanding the basics of d-electron configuration and the spin state of coordination complexes are essential elements of undergraduate inorganic chemistry. However, students in these courses find it difficult to conceptualize the ideas. Here, we have developed an undergraduate laboratory experiment that allows students to systematically…

Science teachers struggle to implement and sustain new curricular ideas from professional development (PD) experiences. These PD opportunities are crucial for enacting real-world changes to teaching practice and address pressing global challenges, such as the teaching and learning of socioscientific topics nested in school communities.…

Language is a fundamental tool for learning science. This study highlights the importance of teacher knowledge in utilising language as a tool for knowledge generation in the classrooms. This case study examines elementary teachers' development of declarative, procedural, and epistemic knowledge related to using language, particularly focusing on…
