This study aimed to investigate the effect of the analytical chemistry laboratory (ACL) course, designed, and conducted according to the flipped learning approach (FL) on prospective science teachers' (PSTs) meaningful understanding and interpretation of knowledge in the context of the environment. Seventy-three second grade PSTs participated in…

[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…

The advancement of breakthrough concepts in science and their implementation in society can only be achieved by starting early with the education of new generations of scientists. The concept of 'Replacement, Reduction and Refinement' (the 3Rs) in regards to animal use was first described by Russell and Burch in 1959. The 3Rs have nowadays a…

Designing high school chemistry assessments is a complex and difficult task. Although prior studies about assessment have offered teachers guidelines and standards as support to generate quality assessment items, little is known about how teachers engage these supports or enact their own beliefs into practice while developing assessments.…

This study investigated the perceptions and quality of argumentative and summary writing of the Pre-service Science Teachers (PSTs) who participated in a knowledge generation approach to learning, which is known as the SWH approach, and who had had experience with it across different time periods. A total of 41 PSTs were divided into three groups…

In this research, the laboratory perceptions of pre-service science teachers with different goal orientations in analytical chemistry courses in which an inquiry-based laboratory approach had been adopted were examined in a case study. From the pre-interviews conducted with 37 pre-service science teachers, 3 preservice science teachers with…

In this study, it was aimed to investigate the effects of microscope simulation software on prospective science teachers' laboratory achievements, microscope use, laboratory reports and views on microscope which was prepared for general biology laboratory. The case study design was adopted for the research. The participants were 49 science teacher…

This paper highlights learning supports associated with genetics lessons that were implemented in a urban high school biology classroom. The supports provided access to science content for ELLs [English language learners], students with IEPs [individualized education programs], and struggling readers during an introductory unit on genetics. Due to…

The current study presents an evaluation of the laboratory instructional tasks prepared based on innovative teaching approaches (research-inquiry, problem solving, project, argumentation and web-based interdisciplinary learning approaches) designed to enhance science teachers' biotechnology knowledge, awareness and laboratory experiences. The…

This study was carried out to investigate pre-service teachers' perceived ease of use, perceived usefulness, attitude and intentions towards the utilization of virtual laboratory package in teaching and learning of Nigerian secondary school physics concepts. Descriptive survey research was employed and 66 fourth and fifth year Physics education…

The ability to develop, use, and refine models of experimental systems is a nationally recognized learning outcome for undergraduate physics lab courses. However, no assessments of students' model-based reasoning exist for upper-division labs. This study is the first step toward development of modeling assessments for optics and electronics labs.…

The purpose of this paper is to develop a "valid and reliable laboratory safety questionnaire" which could be used to identify science teachers' understanding about laboratory safety issues during their science laboratory activities. The questionnaire was developed from a literature review and prior instruments developed on laboratory…

In this paper, we examined teachers' understanding of electrical concepts such as power, current and potential difference based on how these concepts were applied to understand the relative brightness seen in bulbs of different wattage under different connections--series or parallel. From the responses of teachers to a concept question, we…

Graduate students who fulfill teaching roles in the undergraduate laboratory play an important role in establishing a positive learning environment. A host of various graduate teacher training programmes have been developed, implemented and evaluated accordingly in order to enhance their teaching capability. In addition research has also…

In this study, the views of Serbian chemistry teachers (N = 334) on the ways in which contemporary chemistry curricula stimulate the creativity of students were surveyed. The majority of the teachers have a positive attitude towards promoting creativity through teaching chemistry. Most of them also stated that their teaching practice contained…
