Existing evidence has demonstrated that educators often lack the competencies required to address science, technology, engineering, and mathematics (STEM) related issues and problems when teaching. As such, a need existed to identify ways to help preservice students negotiate meaning, construct knowledge, and become empowered to facilitate the…

Three-dimensional visualization of molecular simulations in virtual reality (VR) is an emerging teaching tool in chemical education. This work describes a VR application which can generate a 3D molecular dynamics (MD) simulation from arbitrary molecular structures and renders that MD simulation trajectory on a VR headset in real-time. This system…

One of the most fundamental strategies in mathematics instruction is practice problems because teachers know that practicing a skill improves performance. At the same time, teachers also know that just because students can correctly answer practice problems does not mean they fully understand the concept or how to apply a formula--especially not…

The aim of this study was to determine the correlation between self-, peer- and teacher- assessment to evaluate preservice science teachers' classroom teaching activities. A mixed method was employed. The sample consisted of 55 senior students (29 women, 26 men) from the science teaching program of a public university in Turkey. Quantitative data…

The aim of this research is to examine the effects of worksheets enriched with concept cartoons used in the teaching of Science Teaching Laboratory Applications-II course on the academic success and metacognition skill levels of science prospective teachers. The study was carried out using semi-experimental design. The sample of the study, science…

This research aims to analyze the effects of argumentation-based teaching (ABT) on the 4th-grade students' academic achievement, argumentative tendencies and attitude towards science. The universe of the research was 4th-grade students studying in Yigilca district of Düzce province in the 2017-2018 academic year, in Turkey. The sample of the…

A study was conducted to explore the beliefs and practices of 49 New South Wales (NSW) primary school teachers regarding their beliefs and practices concerning the use of concrete materials in the learning and teaching of Number and Algebra. This paper reports on elements of the study regarding why and how teachers use concrete materials. Not only…

An undergraduate teaching laboratory experiment involving a continuous flow, photocatalytic thiol-ene reaction using visible-light irradiation is described that allows students to explore concepts of green chemistry, photochemistry, photocatalysis, and continuous flow chemistry.

In this paper, we highlight examples from school mathematics in which invariance did not receive the attention it deserves. We describe how problems related to invariance stimulated the interest of both teachers and students. In school mathematics, invariance is of particular relevance in teaching and learning geometry. When permitted change…

With over 1,400 known disease-causing organisms in humans alone, and hundreds of named infections, the realm of Medical Microbiology is both fascinating and intimidating. The wealth of information covered in this subject area often demands much memorization that can be difficult to handle. By integrating key concepts and terminology of this…

"For every action there is an equal and opposite reaction." "Except when a bug hits your car window, the car must exert more force on the bug because Newton's laws only apply in the physics classroom, right?" Students in our classrooms were able to pick out definitions as well as examples of Newton's three laws; they could…

This study aimed to present a module related to the use of concept cartoons integrated into problem-based learning (PBL) method in science lessons. As part of the study, concept cartoons were developed based on scenarios dealing with daily life situations. A module was designed using these concept cartoons. The module focused on the topic…

Concept mapping helps learners to understand complex ideas. However, studies confirming that statement are scarce. A quasi-experimental and Design-based approaches were applied to understand the effectiveness of concept mapping based teaching method on grade eight students' conceptual understanding of photosynthesis. Two sections of grade eight…

Self-efficacy plays a key role in determining teaching practices. Still, concerns regarding the low science self-efficacy beliefs held by elementary teachers have raised questions about the effectiveness of teacher preparation programs. Previous research has been restricted to labeling preservice elementary teachers as having high, medium, or low…

This study investigated how practice-based science methods courses, at three different institutions, provided opportunities for preservice teachers (PSTs) to develop new ways of enacting and noticing ambitious teaching through analyzing rehearsal lessons. We examined 194 written rehearsal reflections for similarities and differences in the types…
