We developed a single crystal X-ray crystallography experiment based on the crystal structure of sucrose (table sugar), and a more challenging experiment using Epsom salt. Both crystals are readily available in X-ray quality crystalline form. In these experiments, students mounted a crystal on a MiTeGen loop and analyzed it using a Rigaku XtaLAB…

General chemistry courses serve as foundational curriculum within most STEM undergraduate curricula, and hence, it is essential to assess student knowledge and application of learning outcomes for courses such as Introduction to Chemistry and Organic Chemistry. Within the United States, paper-and-pencil examinations are typical for measuring…

An increased reliance on nanotechnology and recent developments in materials fabrication coincide with a greater prevalence of 3D printers in high schools. We developed this lesson to foster an exploration of interdisciplinary fields and to increase access to recent advances in materials chemistry through two different learning modules. The lab…

Language, and thus scientific language, is essential for chemistry teaching and learning. To be able to successfully teach the scientific language of chemistry, the Chemish, (prospective) chemistry teachers need to possess pedagogical scientific language knowledge (PSLK).Thus, teacher preparation needs to focus explicitly on Chemish and its…

This study reported the application of an interactive Open Education Resource, namely, an open virtual experiment simulator education tool (OVESET), in teaching the kinetics of atom transfer radical polymerization (ATRP) in a polymer science classroom. The OVESET ATRP kinetic simulator aims at improving students' inductive reasoning skills.…

While there have been an increasing number of evidence-based instructional strategies propagated, less literature exists on how to propagate a curriculum. This paper is meant to present how the theory of "Design-Based Implementation Research" (DBIR) can be used as a framework to propagate such innovative curricula. DBIR is a research…

Recently, the chemistry education community has focused considerable effort on incorporating systems thinking into chemistry education as a means to address global challenges such as sustainability. In this project, a series of exploratory workshops was held with secondary educators (N = 12) and tertiary educators and researchers (N = 16),…

Given the big gap between rural areas and cities and developed areas of China in basic education, it is of great significance to train a large number of excellent teachers for basic education in the vast rural areas so as to boost basic education there and achieve educational equity. Hanshan Normal University is a regional normal university…

The "Atoms-First" approach has received considerable attention in the chemical education community over the past few years as an alternative to the standard reaction-based two-semester General Chemistry curriculum. The Atoms-First model emphasizes the electronic structure of the atom as a means to explain and rationalize chemical…

The research was carried out through research and development to produce an innovative chemistry laboratory workbook (InoChemLaW) followed by the implementation of the learning package in the teaching of chemistry. The result showed that a standard InoChemLaW has successfully been developed on the topic of Colligative Properties of solutions. The…

In recent years, educational researchers have investigated teacher-student interactions in science classrooms, paying particular attention to interaction patterns and the purpose of such interactions. Although different patterns and purposes have been uncovered through these investigations, there is little research on how college instructors use…

This research aimed to provide an innovative chemistry learning material with guided tasks to improve students' competence in Chemistry. It involved 180 students enrolled in the Analytical Chemistry course at State University of Medan in academic year of 2016/2017. The samples were purposively selected and divided into two groups. The research…

This study aims to identify the contributions of teacher competency on teaching and learning for the subject of chemistry for the practical design, planning, and implementation to assessment of practical exercises in the science laboratory. The study used survey method with a five-point Likert scale questionnaire. The questions focused on…

This study aimed at portraying the implementation of inquiry-based chemistry learning in the city of Jambi, Indonesia during the curriculum reformation era. The study included pre-existing supports for and situational beliefs towards the use of the strategy. The results of a questionnaire (n=99) revealed that inquiry had been minimally adopted in…

This paper presents the findings of a study that explored the link between teachers' views on the challenges to inquiry-based science teaching (IBST) practice in the chemistry classroom and their need for professional development. The study used a multiple case study design and collected data using interviews. Participants were purposively…
