Introductory physics lab instruction is undergoing a transformation, with increasing emphasis on developing experimentation and critical thinking skills. These changes present a need for standardized assessment instruments to determine the degree to which students develop these skills through instructional labs. In the first part of this thesis,…

With the benefits of low cost, energy efficiency, and environmental protection, photocatalytic hydrogen production is considered to be the most promising technology for the development of a clean and sustainable society. However, the utilization of photocatalytically generated hydrogen is not very common yet. Therefore, tertiary education urgently…

Students in environmental sciences, ecology, or wildlife management are often reluctant to acquire training in basic laboratory techniques. To advocate the importance of this training, we reviewed literature in the fields of biological and environmental science for one frequently used technique--centrifugation--and evaluated whether centrifugation…

Introductory physics labs often focus on a series of common experiments intending to teach the student the measurement side of physics. While these experiments have the potential to be quite instructive, we observed that our students often consider them to be boring and monotonous, which often leads to them being uninstructive. To combat this, we…

According to variation theory, it is essential to enable students to focus on the object of learning and discern its critical features, but the features that "it is possible" to discern often depend on the equipment used. Thus, in labs, the experimental technologies used may shape students' experience of focal phenomena, in a…

A physics laboratory instructor used action research to effectively implement a 5E instructional approach, which incorporated scientific practices. The instructor explored how to integrate the instructional approach into practice, challenges present in the implementation, and students' learning experiences. The data were collected during three…

This dissertation examines, in three studies, undergraduate student experiences in social aspects of online learning when conducting remote physics laboratories. The first quantitative, observational study examined introductory students' epistemological, socialization, and help seeking views (N=998). Parametric and nonparametric tests indicated no…

The Survey of Physics Reasoning on Uncertainty Concepts in Experiments (SPRUCE) was designed to measure students' proficiency with measurement uncertainty concepts and practices across ten different assessment objectives to help facilitate the improvement of laboratory instruction focused on this important topic. To ensure the reliability and…

The existence of gender differences in student performance on conceptual assessments and their responses to attitudinal assessments has been repeatedly demonstrated. This difference is often present in students' preinstruction responses and persists in their postinstruction responses. However, one area in which the presence of gender differences…

Science anxiety, which is one of the affective dimensions in science learning, is one of the factors affecting success in Science and has been studied for 35 years. The existence of considerable negative attitudes towards Physics courses, which is one of the basic branches of Science, is a fact. This research has been designed to identify the…

The purpose of this study was to identify the perceptions of pre-service science teachers about using vee diagrams and preparing electronic portfolios in physics laboratuary course. 103 first grade pre-service science teachers who took general physics laboratuary course were the participants of the study. Pre-service teachers constructed vee…

Undergraduate research experiences (UREs) have been endorsed as a powerful instructional tool in higher education; however, relatively little is known about the long-term effects of participation in these programs. The purpose of this study was to investigate the educational enhancements of URE participation from the perspective of practicing…

Practical work in school science plays many essential roles that have been discussed in the literature. However, less attention has been paid to how teachers learn the different roles of practical work and to the kind of challenges they face in their learning during laboratory courses designed for teachers. In the present study we applied the…

Research on conceptual change assumes that students enter a science classroom with prior(mis-)conceptions. When being exposed to instruction, students are supposed to develop or change their conceptions to (more) scientific concepts. As a consequence, instruction typically concentrates on appropriate examples demonstrating that students'…

Designed to accompany the student text on respiration, this manual presents instructions on the use of laboratory equipment and presents various experiments dealing with the concepts presented in the text. Thirty-nine laboratory activities are described. Laboratory activities are divided into several parts, each part covering a specific experiment…
