An augmented reality (AR) application and an activity worksheet have been developed to support students in visualizing the concepts involved when solving [superscript 1]H NMR problems. This instructional resource was designed to encourage conceptual problem-solving and prevent memorization by eliminating the use of chemical shift tables. It uses…

Project-based (research-driven) laboratory courses stimulate student involvement, improve critical thinking and initiate cooperative learning. To this end, a 7-week laboratory project was designed for a sophomore cell biology course to reinforce the fundamental relationship between genotype and phenotype using yeast alcohol dehydrogenase I (ADH1).…

The concept of hybridisation is one of the most difficult concepts for chemistry students to grasp at all levels of learning. Research showed the students conceptual difficulty ranged from their lack of the prerequisite knowledge for grasping the topic hybridisation to chemical bond formation and orientations of atomic orbitals. This study…

Getting students to understand the particulate nature of matter is a major challenge for chemistry education. In upper secondary school students commonly struggle to distinguish between intra- and intermolecular bonding and analyse chemical bonding in terms of electronegativity. In this study, we explore how creative drama may be used in chemistry…

The aim of this study is to examine the effects of computer-based analogy (CBA) used in science teaching in terms of the unit of Structure and Properties of Matter on seventh-grade students' academic success. The attitudes of students against science teaching lesson were also described in this study. This study was applied to 60 seventh-grade…

To learn to read, the brain must repurpose neural systems for oral language and visual processing to mediate written language. We begin with a description of computational models for how alphabetic written language is processed. Next, we explain the roles of a dorsal sublexical system in the brain that relates print and speech, a ventral lexical…

A procedure for the solution polymerization of styrene using di-"tert"-butyl peroxide (DTBP) as the initiator is described. The use of DTBP allows for end-group analysis by [superscript 1]H NMR spectroscopy and calculation of the number-average molecular weight of the polymer. This experiment was designed as a laboratory introduction to…

Understanding macromolecular structures is essential for biology education. Augmented reality (AR) applications have shown promise in science, technology, engineering, and mathematics (STEM) education, but are not widely used for protein visualization. While there are some tools for AR protein visualization, none of them are accessible to the…

Students often have difficulty understanding abstract concepts in chemistry and a low spatial ability, especially in visualizing intermolecular interactions at the submicroscopic level. Therefore, this study aims to analyze the spatial ability of students by using a 3D virtual representation as they study the curriculum topic of molecular…

At an advanced stage of learning quantum chemistry, undergraduate students usually encounter simple Hückel-molecular-orbital (HMO) theory, whose primitive approach gives very useful insight into the electronic structure of p-conjugated molecules. However, on one hand, computational HMO software, when programmed without using molecular symmetry,…

The laboratory practice "Primary culture and directional differentiation of rat bone marrow mesenchymal stem cells (BMSCs)" is part of a required course for sophomore medical students at Tongji university, which has been conducted since 2012. Blended learning has been widely applied in medical courses. Based on a student-centered…

Facile visualization of biomolecules is an essential component of the undergraduate biochemistry curriculum. In the past, a number of tools have been used to display biomolecules. More recently, the advent of greater accessibility to virtual reality (VR) and augmented reality (AR) programs has created a new mechanism to visualize biomolecules.…

This study reports the effectiveness of nanoscience activities in enhancing secondary school students' understanding of two chemistry concepts: structure of atom and acid and bases. For the purpose of this study, quasi experiment was employed to 163 Grade 10 students from the Northern Region of Malaysia. Sample from the experimental group was…

This study analyses the evolution of school-level scientific models proposed by prospective pre-primary teachers (PPTs) (a) about the water molecule and its intermolecular bonds, and (b) representing the different states of water molecule aggregation at a microscopic level. The data were acquired from the PPTs' responses at the beginning and at…

Enzyme kinetics is the study of enzymatic catalytic rates in biochemical reactions. This topic is commonly taught to life science students in introductory biochemistry courses during their undergraduate education. Unlike most other biochemistry topics, which focus on visual structures of biomolecules and their processes, enzyme kinetics is…
