In 2002, the Swedish National Food Agency and researchers from Stockholm University made an announcement regarding the presence of acrylamide in carbohydrate-rich foods that are exposed to high temperatures, with cereals, potatoes, and coffee possibly being the most significant sources of ingestion. Although limited data are available on assessing…

Assessing student learning to adapt instruction to support learning is an important skill all teachers need to develop. However, it is not an easy task for teachers and even more difficult for new teachers. The current study aims to explore an alternatively certified new chemistry teacher?s understanding and practices of classroom assessment to…

Awareness of best safety practices in the industrial sector will allow students in chemistry and chemical engineering programs to apply these approaches to their own safety assessments. Process safety is a critical function within the pharmaceutical industry to ensure safety when performing reactions. An introduction to process safety and a series…

Graduate teaching assistants (GTAs) hold a unique positionality as instructors and research mentors to undergraduate students, research mentees to faculty members, and employees to an institution. With limited pedagogical training and teaching resources, the enactment of planned teaching activities and learning resources may be influenced by how…

This research aimed to investigate the expectations and gains of teachers who designed and used context-based teaching materials in their classes and to reveal their views on the applicability of this teaching approach. The methodology of this research was the case study. The research was carried out with two chemistry teachers who participated in…

In this study, we explored undergraduate chemistry education at Kotebe University of Education (KUE) in terms of the ontological orientations, patterns and source domains of educators' and undergraduate students' sense of the atom. Due to the ambiguity and controversy regarding atomic ontology as a case of interest and the requirement for a…

Teachers' responses to student contributions in science classroom influence the resulting classroom interaction. To establish a heightened interaction, teachers need to use specific discursive moves. Using the notion of noticing as a lens, in this qualitative case study, I report on how the notion of noticing and responding with a suitable…

Mastery goal structures, which communicate value for developing deeper understanding, are an important classroom support for student motivation and engagement, especially in the context of science learning aligned with the Next Generation Science Standards. Prior research has identified key dimensions of goal structures, but a more nuanced…

The inclusion of engineering practices poses a challenge for many science teachers trying to meet the expectations of the Next Generation Science Standards because they lack formal training in engineering. This, however, may provide an opportunity for science teacher educators striving to improve the use of learner-centered teaching practices by…

Laser-induced breakdown spectroscopy (LIBS) and principal component analysis (PCA) are frequently used for analytical purposes in research and industry, but they seldom are part of the chemistry curriculum or laboratory exercises. This case study paper describes the combined application of LIBS and PCA during a research internship for an…

Phosphates are essential components of any efficient fertilizer. Natural phosphate rock is, however, not available in every part of the world. According to the European Commission, phosphate rock has high economic importance as well as a certain supply risk--at least for Europe. For these reasons, environmental technology research has received a…

The case study approach provides students with a better appreciation of how scientists solve problems and conduct themselves in the "real world". When applied to the undergraduate chemistry laboratory, this approach also challenges critical thinking skills and creativity in ways "cook book" experiments very often do not. This…

Classroom response systems are an important tool in many active learning pedagogies. They support real-time feedback on student learning and promote student engagement, even in large classrooms, by allowing instructors to solicit an answer to a question from all students and show the results. Existing classroom response systems are general purpose…

Background: There is a critical need for evidence-based metacognition instruction models with an ease of implementation. Three issues involved in advancing the implementation and assessment of metacognitive interventions are: (i) the lack of an operational framework for the development of metacognition; (ii) metacognition instruction models that…

The aim of this research was to examine the effects of a new platform for raising the pre-service chemistry and geography teachers' awareness of cooperation possibilities associated with the planning relevant interdisciplinary lesson. The research featured the participation of 16 students of the Faculty of Chemistry and 28 students of the Faculty…
