This paper describes the development of a fully remote upper-class biochemistry lab course. The sudden change to online teaching in the middle of spring semester 2020 had a primarily negative impact on laboratory teaching. These effects were mitigated because the students had done many of the basic hands-on procedures before the switch. A true…

Three direct complexometric titration methods for bismuth subsalicylate determination in over-the-counter stomach relief caplets and liquids are presented, as well as a UV-vis assay, for use in student laboratories. The main difference between titration methods is the choice of indicator; either xylenol orange (XO), pyrocatechol violet (PV), or…

Students' recognition of the common procedural mistakes in the chemistry laboratory was examined in this study. Data were collected from 49 undergraduates studying Science Teaching. A video in which a student is purposefully making common procedural mistakes was shown to the students, and they were asked to recognize the mistakes. A Written…

The analysis of spontaneous tail coiling (STC) in zebrafish embryos is a functional parameter that allows the study of motor development. It has recently gained relevance as a biomarker to assess the neurotoxicity of environmental substances. Its practicability in the laboratory makes it an excellent pedagogical tool for promoting students'…

The present study investigated if the argument-driven inquiry (ADI) model with embedded explicit-reflective teaching of NOSI improved pre-service science teachers' (PSTs) comprehension of the nature of scientific inquiry (NOSI). The study employed the qualitative experiment method with 16 PSTs. The PSTs working in small groups conducted seven ADI…

The purpose of this study was to investigate whether the course, Scientific Inquiry, significantly increased the self-efficacy beliefs of its students. According to Bandura (1977), an increase in self-efficacy could increase the likelihood that teachers implement scientific inquiry in their classrooms. I explored self-efficacy in an effort to…

Integrating new synthetic methods and experimental techniques from the latest research reports into undergraduate laboratory experiments is of great significance, as it enables students to learn the cutting-edge technology of organic chemistry and cultivates their experimental skills and innovative thinking. In this study, an experiment on their…

Inclusion of a diverse group of students, both regular learners and learners with special needs in chemistry classrooms is an important goal of chemistry educators. However, alternative conceptions in chemistry among high-school students can be a barrier for completing the learning process in the classroom, especially in a heterogeneous class.…

Background and purpose: Most studies have agreed on the benefits of students' participation in discussing socio-scientific issues (SSIs), but few have focused on the serial behaviors through which students declare their positions. Design and method: This study analyzed the serial behaviors of university students when participating in the…

This study aimed to examine learners' perspectives on the hybrid learning approach, using printed modules and social media as learning materials to redesign science courses and improve their performances. This study involved 37 students from Tacuyong Sur National High School, 20 from the Grade 9 class and 17 from the Grade 12 Technical Vocational…

This paper presents a cooperative learning activity on a nuclear power plant to develop students' reasoning skills on socioscientific issues. To this end, the steps in the implementation of the activity have been given in detail. The activity was implemented in an undergraduate course with senior preservice science teachers, whose reflections were…

As a personal avatar, Metaverse can be very effective in science, technology, engineering and mathematics (STEM) classrooms such as science classes that are practical and experimental. In this article, the aim is to report a study related to the perception of teachers and their attitudes towards the use of metaverse tools in teaching elementary…

Over the years, the evolution of science along with technology, engineering, and mathematics has been noticeably evident while science education, on the other hand, has shown little development. The research study aimed to investigate future change initiative implementation in secondary science curricula. In addition, the purpose of the research…

In this study, it is aimed to examine the cognitive structures of pre-service science teachers regarding the concept of "micro teaching". The study was carried out with 25 teacher candidates studying in the 4th grade of science teaching at Alanya Alaaddin Keykubat University Faculty of Education in a 4-week period within the scope of the…

To reduce the cost of educational materials needed by students, we generated a no-cost open educational resources (OER) textbook for an undergraduate level cell biology course. Cell biology is part of the curriculum in various undergraduate degrees for science, technology, engineering, and math majors, therefore generation of OER targets a large…
