The main objective of this intervention study was to investigate the effect of three teaching approaches, namely the traditional teaching method (TTM), a teacher-based demonstration experiment (TBDE) and a student hands-on experiment (SHE), on students' academic performance. A total number of 324 senior five students studying chemistry as one of…

This paper presents an analysis of cognitive skill levels expressed in high school students' performance using laboratory simulations. We address lower-order cognitive skills (LOCS) and higher-order cognitive skills (HOCS) situations in a virtual simulation activity, in order to identify and underly further discussions about students' reasoning…

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…

This paper examines the effectiveness of adding an online component to the general chemistry laboratory in which students view prelaboratory instructional materials through online videos prior to completing general chemistry laboratory activities. Using a quasi-experimental design, we compared the performance of 1089 general chemistry students who…

Recent examples of high-impact teaching practices in the undergraduate chemistry laboratory that include course-based undergraduate research experiences and inquiry-based experiments require new approaches to assessing individual student learning outcomes. Instructors require tools and strategies that can provide them with insight into individual…

The study aims to search the effect of guided inquiry laboratory experiments on students' attitudes towards chemistry laboratory, chemistry laboratory anxiety and their academic achievement in the laboratory. The study has been carried out with 37 third-year, undergraduate science education students, as a part of their Science Education Laboratory…

This research study is an investigation of student-laboratory (i.e., lab) learning based on students' perceptions of experiences using questionnaire data and evidence of their science-laboratory performance based on paper-and-pencil assessments using Maryland-mandated criteria, Montgomery County Public Schools (MCPS) criteria, and published…

We report one teacher's response to a top-down shift from external examinations to internal teacher assessment for summative purposes in the Republic of Ireland. The teacher adopted a comparative judgement approach to the assessment of secondary students' understanding of a chemistry experiment. The aims of the research were to investigate whether…

Student outcomes in online courses trail considerably behind those in face-to-face courses. In order to gain insight into why this might be, the Community College Research Center (CCRC) undertook a series of studies that examined 23 high-demand, entry-level online courses at two community colleges in one state. CCRC researchers observed the online…

This paper describes an action research approach toward an implementation of a new teaching methodology (specifically active learning) in a preparatory college chemistry classroom. The initial implementation involved the use of process-orientated guided inquiry (POGIL) activities. The treatment classes with either all POGIL activities during…

This study reports the results of a survey of 405 high school students in a school district in the western United States. The data were used to determine why so many students take only the minimal science required for graduation. Key areas addressed included how science is taught; science literacy; science, technology, engineering and mathematics…

Laboratory and demonstration have long been used to supplement lecture in chemistry education. Current research indicates that students are better served by laboratories which exercise the higher-order cognitive skills, such as inquiry-based laboratories. However, the time and the resources available to perform these recommended types of…
