Creativity has become an increasingly important competence in today's rapidly changing times, especially for school graduates who strive for pursuing a technical or scientific career. But creativity has not been integrated in the lessons or curricula of STEM subjects. To successfully integrate it in the classroom, it is important to investigate…

Introductory science courses serve a population of students in the major (i.e., chemistry) as well as those students outside the discipline (i.e., premed, biology, engineering). In an effort to help this diverse population of students connect personally with the content of the course, we sought ways to include student-centered activities, provide…

Stereotype threat theory (STT) offers one explanation for achievement differences in math and science for both women and minority students. Specifically, STT posits that the perceived risk of confirming a negative stereotype about an individual's identity group acts as a psychological burden that negatively impacts performance. This study examined…

This article argues that cross-disciplinary linkages -- that is, relationships among phenomena studied by those in different disciplines -- often serve to destabilize, at least temporarily, systems of stability that are theorized to operate within the sets of phenomena studied within most disciplines. It surveys across disciplines both systems of…

Within the last 10 years, higher education has seen the accelerated development of blended learning (BL), active learning (AL), and STEM education. The presented mixed methods study examined a proposed framework that BL affordances enable or constrain AL, as a representation of constructivist learning theory, and that the relationship between BL…

The aim of this research was to examine the chemical representations that are present in Turkish high school chemistry textbooks. Content analysis was the method of analysis. Four chemistry textbooks, which were commonly used in Turkey, for each grade (i.e., from 9th to 12th), were selected. When evaluating the representations, a rubric including…

Inquiry-based learning is a usable approach in developing gifted and talented students' learning and one that overlaps with their properties and learning needs. The aim of this research was to examine the effect of guided inquiry-based learning approach compared with that of traditional teacher-centered instruction on gifted and talented eighth…

This is a conceptual paper aimed at chemistry educators. The purpose of this paper is to illustrate the use of the semantic code of Legitimation Code Theory in chemistry teaching. Chemistry is an abstract subject which many students struggle to grasp. Legitimation Code Theory provides a way of separating out abstraction from complexity both of…

Terms to be familiar with before you start to solve the test: Southern blotting, Western blotting, restriction endonucleases, agarose gel electrophoresis, nitrocellulose filter, molecular hybridization, polyacrylamide gel electrophoresis, proto-oncogene, c-abl, Src-homology domains, tyrosine protein kinase, nuclear localization signal, cDNA,…

The traditional assignment of oxidation states to organic molecules is problematic. Accordingly, in 1999, Calzaferri proposed a simple and elegant solution that is based on the similar electronegativities of carbon and hydrogen: hydrogen would be assigned an oxidation state of zero when bonded to carbon. Here, we show that X-ray photoelectron…

The goal of this study was to investigate the timing of online homework completion and its effects on student performance. Data was collected from two large, first-semester general chemistry sections at a southwestern university. Specifically, this study aims to explore the link between when students complete their homework relative to the date…

The aim of this study is to establish an empirically substantiated professional development programme for teachers to become lead teachers who are able to support professional development of peers in times of curriculum innovation. The design of a professional development programme, participants' learning outcomes and their interrelatedness are…

This study examines the effectiveness of pre-laboratory presentations in an undergraduate general chemistry laboratory using two different modes of delivery: a traditional lecture versus an in-class video presentation. It was anticipated that implementation of videos could result in improved laboratory efficiency, safety, and necessary technical…

Feedback is an essential formative assessment practice that has the potential to influence student learning and achievement positively. Providing effective feedback, however, is a challenging task for teachers. Especially beginning teachers struggle with the provision of information that supports students in developing and improving their…

For the last seven years, an interdisciplinary course known as "Greener Solutions", offered by the University of California, Berkeley Center for Green Chemistry, has brought together graduate students in chemistry, environmental health, and engineering to understand each other's disciplines, and to work together to develop safer…
