School pedagogies that expand opportunities for learners to build and use knowledge for meaningful purposes are resources for hope. Internationally, standards-based reforms in science education position schooling as a context for building and using disciplinary knowledge to explain phenomena and solve problems. There is also growing research…

Despite national curricula and instructional reforms calling for collaborative problem-solving skills (CPS), however, there is an absence of a theory-laden model showing how to effectively construct CPS for science learning. We therefore developed and validated a simulation-based CPS model that exploits its constructs, sequences, and causal…

There is growing interest in implementing reform-based lab courses in undergraduate physics that are student driven rather than instructor driven. In these courses, students develop and carry out experiments while simultaneously reasoning about their hypotheses, data collection procedures, collected evidence, and the relevant physics content.…

Emphasizing stoichiometry appears to be a norm of introductory chemistry courses. In this longitudinal and mixed-methods study, we examined how the emphasis on stoichiometry in assessments of introductory chemistry impacted educational equity and student learning. Using quantitative methods, we identified mole and stoichiometric conversions as two…

A physiology laboratory course plays an important role in improving the scientific abilities of medical students. This study involved a teaching reform based on problem-based self-designed experiments in a physiology laboratory course. The study subjects were divided into two groups, i.e., students enrolled in 2019 were assigned to the traditional…

It has been well-establishing in the field of educational research that traditional educational methods such as passive lectures and labs where students follow pre-designed procedures to verify information already told to them are not effective for promoting meaningful and lasting conceptual understanding. Alongside this knowledge have come a…

The United States is one of only three countries in the world that remain uncommitted to the metric system. Perhaps to policymakers the decision to hang on to miles, pounds, and gallons is one of tradition. However, as a physics teacher I have seen firsthand how growing up with U.S. Customary Units (commonly called by the pseudonym "British…

National reform documents and shifts in educational standards have continued to highlight the importance of engineering and engineering practices within science literacy. High-quality engineering opportunities must be present in formal education due to their association with problem-solving and critical thinking. Given this directive to reach…

Research shows that U.S. students continue to lag behind in science and mathematics internationally (Fleischman, Hopstock, Pelczar, & Shelley, 2010; Provasnik et al., 2012). A recent study found there is a direct link between students' mastery of academic subjects and their ability to collaboratively problem solve, a critical 21st century…

There have been multiple national calls for curricular reform in science, technology, engineering, and mathematics (STEM), including a need to instill democratic skills in students. Democratic skill building can be embedded in STEM classrooms through intentional "deliberative pedagogies" that include communication, collaboration, and…

The push for STEM has raised the visibility of engineering as a discipline that all students should learn. With the release of the "Framework for K-12 Science Education" and the Next Generation Science Standards (NGSS), engineering now has an official place in the science curriculum. In both the "Framework" and the NGSS,…

The purpose of this study is to understand the nature of pre-instructional knowledge transferred by students into problem situations and the change process on students' knowledge system during classroom discussions. This study was framed by two interrelated theoretical frameworks on knowledge structures, phenomenological primitives and…

This book represents a crop of wide-ranging research conducted by renown scholars in sub-Sahara Africa revolving around mathematics teaching and professional development programs for mathematics teachers. The research-based proposals and actual how-to-conduct professional development initiatives that enhance effective mathematics instruction are…

The Qatari government has made significant changes in the organization and staffing of schools over the past decade in an effort to improve the academic performance of school-aged citizens. Of interest is the need to encourage teachers to move from a didactic teacher-led mode of instruction to one that is more student-centred, but also…

A method is proposed to simplify analytical computations of the transfer function for electrical circuit filters, which are made from repetitive identical stages. A method based on the construction of Pascal's triangle is introduced and then a general solution from two initial conditions is provided for the repetitive identical stage. The present…
