Preparative chromatography is one of the most common and important purification techniques in organic chemistry and is employed in laboratories across the globe. In order to facilitate student proficiency with the method, a unique approach for the separation of estragole, ethyl cinnamate, and cinnamyl alcohol using microscale preparative flash…

Students entering high school often bring misconceptions about the nature of science and experimentation with them from middle school. Many also bring a belief that they are not a "science kid" and, therefore, cannot be a strong student in Biology. This belief can lead to a lack of self-efficacy and of student agency in the classroom.…

When instructors assess students' laboratory reports to appraise the underlying scientific reasoning, they disclose their own concerns, epistemological assumptions and beliefs about science. The analysis of such assessments (i.e. rubric-centred scores and corresponding justificatory comments) offer a wealth of insights that can be re-engaged in…

Increasing student engagement with the social practices of science (i.e., communication, collaboration, and critique) is a goal throughout K-16 science education and provides an opportunity for science educators to leverage student discourse to optimize learning. Yet how instructors can encourage forms of discourse which predict increased…

We present the development and evaluation of "da Vinci's Curse", a chemistry escape room experience designed to consolidate laboratory skills in a fun and interactive setting. Inspired by the maestro, Leonardo da Vinci, the escape room challenges students to complete a series of puzzles in teams to escape "da Vinci's Curse".…

Recent emphasis on learning biology through scientific investigations has focused instruction on understanding and using scientific evidence. To unpack the complexities of evidentiary reasoning, here we present a novel laboratory investigation for teaching the Hardy Weinberg Equilibrium (HWE) in an introductory biology laboratory course that was…

A growing body of literature focusing on undergraduate biology education calls for students to engage in the ways of thinking, feeling, and doing that reflect those in which biologists engage. Such reform efforts suggest that learning is best fostered when students engage in practices, concepts, and scientific reasoning as they endeavor to explain…

[This paper is part of the Focused Collection on Instructional labs: Improving traditions and new directions.] Research on nontraditional laboratory (lab) activities in physics shows that students often expect to verify predetermined results, as takes place in traditional lab activities. This understanding of what is taking place, or…

As college biology educators we want students learning how to conduct their own scientific investigations. This means designing laboratory curricula in which students exercise control and responsibility over the knowledge building actions of an investigation--that is, in which they exercise "epistemic agency." Our current understanding…

In this study, it was aimed to investigate the effects of guided inquiry learning approach-based laboratory applications on the scientific reasoning skills of pre-service science teachers with different cognitive styles. Additionally, the opinions of pre-service science teachers with different cognitive styles about the effects of the application…

Students who experience research as undergraduates tend to remain in science, technology, engineering, and mathematics fields. Since course-based undergraduate research experiences (CUREs) are often expensive to implement, we developed a relatively inexpensive first-semester research course for majors entitled "Freshman Research in…

There has been a growing awareness that STEM education should incorporate a wide range of capabilities, in addition to providing traditional theoretical and practical knowledge. In line with these skills, entitled "professional skills," GTIIT has defined seven core competencies. The enhancement of two of these competencies, namely,…

This study reviewed the green and sustainable chemistry education (GSCE) research that provided training at the tertiary level from 2000 to 2024. The Web of Science and ERIC databases were screened using title and abstract review. In total, 49 studies were analysed. The analysis instrument has two main parts, namely, general characteristics of the…

The aim of this study is to determine the trend of studies in the laboratory and put the current situation in Turkey. For this purpose, document analysis technique, one of the qualitative research methods, was used in the research. The data group of the research consists of thesis studies on laboratories in our country between 1999-2017. Theses in…

The role of the school science laboratory, once taken for granted as verification of taught theory using prescribed ('cookbook' to critics) practical activities, has become less clear since the emergence of the 'inquiry' paradigm in which the school laboratory would appear to become a make-believe science research laboratory. But a school science…
