Student-generated videos are growing in popularity in education generally, and in chemistry education there are several reports emerging on their use in practice. Interest in their use in chemistry is grounded in the visual nature of chemistry, the role of laboratory work in chemistry, and a desire to enhance digital literacy skills. In this perspective, we consider the place of student-generated videos in chemistry education, by first considering an appropriate pedagogical rationale for their u...

The galvanic cell is a basic concept in electrochemistry. To assess mainland Chinese students’ proficiency levels in galvanic cells, the Galvanic Cell Proficiency Level Assessment (GCPA) was developed based on the Rasch model. The GCPA was developed through a pilot test and consists of seven multiple-choice questions and four open questions. The assessment instrument was administered to 621 high school students in the 11th grade, and the test results showed good reliability and validity. The int...

The purpose of this descriptive case study was to develop pre-service chemistry teachers’ Technological Pedagogical Science Knowledge (TPASK) through novel computational chemistry modules. The study consisted of two phases starting with designing a computational chemistry based learning environment followed by a case study where students’ perceptions towards educational computational chemistry were explored. First, we designed an authentic research-based chemistry learning module that supported ...

The concept of delocalization (i.e., resonance) is fundamental concept in organic chemistry but essential learning outcomes (LOs) have not previously been proposed nor has there been an analysis of how resonance is taught, despite indications in the literature that students have many non-canonical ideas about the concepts. To address this deficit, we first developed a set of ten learning outcomes believed to be essential to the concept of delocalization in organic chemistry, especially for stude...

We developed an online learning module called “Organic Mechanisms: Mastering the Arrows” to help students learn part of organic chemistry's language—the electron-pushing formalism. The module guides students to learn and practice the electron-pushing formalism using a combination of interactive videos, questions with instant feedback, and metacognitive skill-building opportunities. This module is part of OrgChem101.com, an open educational resource (OER) that houses a series of learning modules....

Creativity has become an increasingly important competence in today's rapidly changing times. It is a central aspect of social development, but it is hardly discussed in schools and often neglected in the natural sciences. In order to promote creativity in science teaching in a targeted way, it is important to understand the perspectives and views of prospective teachers on this topic. For this purpose, a qualitative cross-sectional study was conducted with 83 German chemistry student teachers a...

Preparatory or bridging courses are widespread and have a long tradition at universities. They are designed to increase students’ academic success – in particular of students with low prior knowledge – and to reduce dropout rates. However, critics of these short and compact bridging courses complain that preparatory courses are not able to fill in content gaps sufficiently in a few weeks. Despite the high prevalence of university bridging courses, little is currently known about the sustainable ...

Explanations of phenomena in chemistry are grounded in discussions of particulate-level behavior, but there are limitations to focusing on single particles, or as an extension, viewing a group of particles as displaying uniform behavior. More sophisticated models of physical processes evoke considerations related to the dynamic nature of bulk solutions, in which an ensemble of molecules exists with a distribution of values that vary with respect to different parameters (e.g., speed, kinetic ener...
