The profound advances in the biomolecular sciences over the last decades have enabled similar advances in biomedicine. These advances have increasingly challenged our abilities to deploy them in an equitable and ethically acceptable manner. As such, it has become necessary and important to teach biomedical and scientific ethics to our students who…

Exothermic reactions can present safety hazards and there is a recognized need for reaction safety education at the undergraduate level. We present an experiment that illustrates the pitfall of direct scale-up of an exothermic reaction that can lead to thermal runaway. The iodide-catalyzed hydrogen peroxide decomposition reaction yields…

The aim of this study was to develop a three-tier concept test to determine high school students' conceptual understanding in terms of chemical bonding, and at implementing a reliability and validity study for the test. A total of 175 high school students participated in the research. A three-tier test of 15 questions was employed in the study.…

Chemistry is a highly abstract discipline that is taught and learned with the aid of various models. Among the most challenging, yet a fundamental topic in general chemistry at the high school level, is molecular geometry. This study focused on developing exemplary educative curriculum materials pertaining to the topic of molecular geometry. The…

In order to reach students who can efficiently use intended scientific understandings, it is important to have science teachers without conceptual difficulties. The aim of present research is to enhance pre-service science teachers' conceptual understanding about boiling by dialogic teaching. The sample consisted of forty-three pre-service science…

This study aims to predict the academic achievements of Turkish and Malaysian vocational and technical high school (VTS) students in science courses (physics, chemistry and biology) through artificial neural networks (ANN) and to put forth the measures to be taken against their failure. The study population consisted of 10th and 11th grade 922 VTS…

One of the greatest advantages of augmented reality (AR) in education is that AR increases student motivation. Nevertheless, there is a gap between the research on student motivation in AR and the definition of frameworks to inform and guide the design and development of AR applications that effectively support student motivation. In this paper,…

The Advanced Placement (AP) program has undergone two major reforms in recent decades: the first aimed at increasing access and the second at increasing relevance. Both initiatives are partially designed to increase the number of high school students from low-income backgrounds who have access to college-level coursework. Yet critics argue that…

This case study explored chemistry teacher isolation through the compilation and analysis of contextual characteristics and student performance data of 895 public schools and 2321 chemistry teachers in New York State in 2011-12. Data on the teachers' qualifications along with school characteristics were collected from several independent, publicly…

Given that students are constantly communicating and documenting special experiences in their social and private lives with digital devices, we suggest that this behavior could be used to record and deepen learning experiences-such as visualizing reactions at the molecular level-in a chemistry class. An example would be the creation of stop-motion…

Women and some racial and ethnic groups remain underrepresented in chemistry departments across the United States, and generally, efforts to improve representation have resulted in minimal or no improvements in the last 10 years. Here, we present the outcomes of a graduate-student-led initiative that sought to assess the issues affecting…

The aim of this study was conducted to evaluate chemistry education in the context of the elements that form the learning environment. The weights of learning environment components were determined by Analytic Hierarchy Process. The significance levels of learning environment dimensions were also calculated. According to the findings of the study,…

Visualizations and visual models are of substantial importance for science learning (Harrison and Treagust, 2000), and it seems impossible to study chemistry without visualizations. More specifically, the combination of visualizations with text is especially beneficial for learning when dual coding is fostered (Mayer, 2014). However, at the same…

In this study, action research was used over two years to refine the implementation of process-oriented guided inquiry learning for chemistry students in an academic development programme at a research-intensive South African university. Students' responses to guided inquiry were collected based on a three-pillar framework underpinned by cognitive…

As part of a revision to the content and delivery of first-year chemistry instruction at the University of British Columbia's Okanagan campus, we have employed the United Nations Sustainable Development Goals (UN SDGs) as a thematic framework. This framework was introduced to promote the achievement of affective learning outcomes, including a…
