This experiment was designed and successfully introduced to complement the nanochemistry taught to undergraduate students in a useful and interesting way. Colloidal Ag nanoparticles were synthesized by a simple, room-temperature method, and the resulting suspension was then used to study the surface-enhanced Raman scattering (SERS) of methylene…

This paper describes a new approach for learning from homework called Peer-Assisted Reflection (PAR). PAR involves students using peer feedback to improve their work on open-ended homework problems. Collaborating with peers and revising one's work based on the feedback of others are important aspects of doing and learning physics. While notable…

In order for students to move from using concrete materials to using mental strategies and from additive to multiplicative thinking, the use of arrays and visualisation is pivotal. This article describes a lesson in which students are taken through a Concrete-Representational-Abstract (CRA) approach that involves noticing structure, using…

Traditionally, the subject of neuroscience has been one of the most difficult courses for medical students in undergraduate medical education. Over the last few decades, a fear of neurology and the neurosciences, termed neurophobia, has presented among medical students around the world. Today, neurophobia has resulted in medical students not…

This article demonstrates how to consider differentiating instruction for diverse learners while maintaining the cognitive demand of a mathematics task. The authors present scenarios involving hypothetical cases of students in inclusive classrooms who engaged in productive struggle within the differentiated task. The authors specifically focus on…

Children from low-income families are at greater risk for poor social-emotional development and physical health and may be in need of intervention. This study examined the extent to which the "Positive Action" ("PA") preschool lessons improved low-income children's social-emotional competence and health behaviors. Mixed…

To deepen our understanding of those aspects of problems that cause the most difficulty for solvers, this study integrated eye-tracking with handwriting devices to investigate problem solvers' online processes while solving geometry problems. We are interested in whether the difference between successful and unsuccessful solvers can be identified…

The purpose of this paper is to provide examples of "non-traditional" proof-related activities that can explored in a dynamic geometry environment by university and high school students of mathematics. These propositions were encountered in the dynamic geometry environment. The author believes that teachers can ask their students to…

Computational thinking is an important and necessary way of thinking for computer programmers and other professionals in science, technology, engineering, and mathematics (STEM). Research on emerging practices around computational thinking that is developed through coding initiatives in schools reports that elementary children typically learn how…

Engineering design activities offer the promise of enhanced learning and teaching in pre-college science, technology, engineering, and mathematics (STEM) settings. The wide variation and lack of coherence in research and practice concerning pre-college engineering design challenges necessitates an investigation of the literature. The overarching…

The importance of getting children off to a good start in reading cannot be overstated. Successful academic performance at primary and secondary school level is partly dependent on the ability to read. It is believed that good learners are those who are proficient in reading. However, many learners are struggling to read and, therefore, struggle…

This article describes the implementation of a collaborative--competative pedagogy in a Year 10 class and the productive motivational outcomes that followed.

Single-period inventory models with uncertain demand are very well known in the business analytics community. Typically, such models are rule-based functions, or sets of functions, of one decision variable (order quantity) and one random variable (demand). In academics, the models are taught selectively and usually not completely. Students are…

The study investigates effectiveness of Problem Solving Approach (PSA) in teaching mathematics to students studying at grade 8 in public schools. Pretest-posttest equivalent group design was used to conduct this study. The researcher applied matching technique to place the students in experimental and control groups (CG).Achievement test was used…

This article examines three commonly used pedagogical methods, namely the Socratic method of inquiry, collaborative problem solving, and debate-based deliberation, establishing the relationship of each one of these methods with the strategic promotion of argumentative reasoning, as a commonplace objective and means of inquiry-based educational…
