The purpose of this study was to describe the effect of multiple knowledge representations of physical and chemical changes on the development of primary pre-service teachers' cognitive structures. The study took place in an introductory general chemistry laboratory course in a four-year teacher education program. Multiple knowledge…

Constructing scientific arguments is an important practice for students because it helps them to make sense of data using scientific knowledge and within the conceptual and experimental boundaries of an investigation. In this study, we used a text mining method called Latent Dirichlet Allocation (LDA) to identify underlying patterns in students…

The purpose of this study is twofold: first, to delve into professional development (PD) of science teachers' views about nature of science (NOS) throughout activities linking NOS aspects to science centers (SCs), and second, to reveal how a science teacher uses NOS aspects while teaching in SCs. An instrumental qualitative case study method with…

This research was carried out to investigate the effect of the 5E learning method and 5E method enriched with REACT strategy on student achievement in science education. The research was carried out with 64 first-year students (30 in the experimental groups, 34 in the control groups) in the Department of Primary Education at a state university in…

The use of symmetry is widespread in chemistry, as it is used for predictions of the number of allowed and forbidden absorptions in electronic, vibrational, and rotational spectroscopies; for predictions of the combination of atomic orbitals to produce molecular orbitals; and in many other chemical applications. One critical step in these…

Reorienting organic chemistry laboratories with an emphasis on systemic thinking can only be beneficial to students. Addressing the challenges of climate change and the development of renewable resources with a fundamental reaction, such as the hydrogenation of an alkene, will allow students to see organic chemistry as a science beneficial to…

Embedding science learning in real-world issues is a research-based way to generate student enthusiasm, interest, and motivation for science. The authors advocate teaching secondary science in the context of "socio-scientific issues" (SSI). SSI are authentic societal challenges with connections to science, such as climate change,…

Ms. Jones stared at the stack of biology quizzes and wondered what went wrong. She thought about the lesson plans and wondered what she should have done differently. Ms. Jones is not alone in wondering how to improve student learning and classroom instruction. To improve student achievement, educators must determine what is working and what is…

Following the COVID-19 lockdown, the BSc in Human Biology Program of the University of Nicosia switched from face-to-face to online delivery mode. Herein we describe how we identified and managed the challenges that arose to successfully complete the Semester.

The integration of scientific modeling into science teaching is key to the development of students' understanding of complex scientific phenomena, such as genetics. With this in mind, we conducted an introductory hands-on module during an outreach gene technology laboratory on the structure of DNA. Our module examined the influence of two model…

The phyphox app has demonstrated itself to be useful and impressive for physics teaching. The app is free to download and has so many features that it seems it may be particularly helpful in this time of distance learning. Phyphox (pronounced to sound like "physics") works for Android and Apple phones, and there are many experiments…

For several years, I taught a general education course on the Manhattan Project for students majoring in the arts and humanities who needed a physical science credit as a condition of their graduation requirements. As might be imagined, the challenge in teaching this course was to find a balance between quantitative and qualitative content. A…

COVID-19 has upset the traditional ways of teaching and looks set to continue to have an impact in the coming years. The situation in Taiwan--partial disruption and then an early return to classes--allows for a comparison of student performance in a conventional teaching and testing environment with the non-contact teaching/testing environment…

We present a model of an induction program that supports early career physics teachers as well as experienced teachers who face new challenges in their teaching of physics. The model involves personal mentorship embedded in a teachers' professional community of practice led by senior physics teachers and supported by a physics education research…

Metacognition, the ability to think about and regulate one's thinking, is an important factor in effective student learning. One intervention to promote student metacognition is the exam wrapper--a reflection students complete after an exam noting how their performance related to their preparation. Results are mixed on the effect of the exam…
