Background: Of many innovative laboratory approaches in the literature, POE (Predict-Explain-Observe) and PDEODE (Predict-DiscussExplain-Observe-Discuss-Explain) based laboratories approach have been frequently used to enhance laboratory studies during the last ten years. We contend that excluding the discussion phase before the observation stage…

In many countries, play is the vehicle for teaching and learning, requiring early childhood teachers to recognize and assess children's demonstrations of knowledge and capabilities as they are displayed during play. In the context of science learning, assessing what children know already, referred to as "assessment for learning," equips…

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…

Problem solving is a key component of authentic scientific research and practice in organic chemistry. One factor that has been shown to have a major role in successful problem solving in a variety of disciplines is metacognitive regulation, defined as the control of one's thought processes through the use of planning, monitoring, and evaluation…

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…

When instructors assess students' laboratory reports to appraise the underlying scientific reasoning, they disclose their own concerns, epistemological assumptions and beliefs about science. The analysis of such assessments (i.e. rubric-centred scores and corresponding justificatory comments) offer a wealth of insights that can be re-engaged in…

This study contributes to the growing body of research on the role of crosscutting concepts (CCCs) in three-dimensional teaching and learning by examining the complexity of elementary preservice teachers' (PSTs) knowledge for teaching related to CCCs. The researchers used qualitative methods to analyze PSTs' responses to a questionnaire about CCCs…

This study aims to examine the impact on environmental attitudes and awareness of kindergarten pupils of an intensive education programme based on basic science process skills including the 'reduce, reuse and recycle (3Rs)' paradigm for preschool children. A quasi-experimental pattern with non-equivalent pretest-posttest and with a control group…

Cookbook-style laboratories (labs), where students follow recipes and confirm known results are common, yet years of science teaching and learning research indicate they do not help college students develop the habits of mind and skills of a scientist. We describe the rationale, challenges, and initial changes made in our teaching and learning lab…

Past research repeatedly revealed students' struggles to understand chemical equilibria, especially concerning their dynamic nature. Black-box simulations have proven to be helpful here. However, the effect is strongly dependent on the quality of teaching, the design principles of which are not yet fully known. One aspect of debate concerns the…

Concepts and practices surrounding measurement uncertainty are vital knowledge for physicists and are often emphasized in undergraduate physics laboratory courses. We have previously developed a research-based assessment instrument--the Survey of Physics Reasoning on Uncertainty Concepts in Experiments (SPRUCE)--to examine student proficiency with…

During COVID-19 remote instruction, instructors were tasked with providing students with authentic laboratory experiences in an out-of-classroom environment. One solution developed for our introductory general chemistry laboratory involved students critiquing readily available technique videos to distinguish between correct and incorrect…

A laboratory experiment was designed to introduce the practical application of biocatalysis in Bachelor and Master courses in biotechnology and medicinal chemistry, respectively. To this aim, the lipase from "Candida rugosa" was characterized (protein concentration and activity), immobilized on a carrier (by hydrophobic adsorption), and…

The widespread misperception of science as a deliverer of irrefutable facts, rather than a deliberative process, is undermining public trust in science. Science education therefore needs to better support students' understanding of the central role that disputes play in the scientific process. Successfully incorporating scientific disputes into…
