We present an integrative mixed-methods systematic review of research on laboratory work in secondary-school science education from 1996 to 2019. The aim of the study is to identify important aspects of how to successfully make use of laboratory work as a science-teaching strategy in secondary schools. By engaging teachers, our study uses a…

Study abroad attempts to prepare students to effectively work in a multi-national environment. This study compares students' experiences in a unit operations laboratory course offered in multiple modalities: at students' home university, and four- and eight-week study abroad. The results examine the impact of support on students' learning and…

Sessions of our laboratory-based physics course have been "meeting" synchronously online instead of on campus due to the pandemic. Shifting to remote instruction prompted us to create online versions of the course. In the unit on global climate change, for example, we continued engaging students in documenting their initial and evolving…

Instruction in analog electronics is an integral component of many physics and engineering programs, and is typically covered in courses beyond the first year. While extensive research has been conducted on student understanding of introductory electric circuits, to date there has been relatively little research on student learning of analog…

Learning theories converge on the principles of reflective learning processes and perceive them as fundamental to effective learning. Traditional laboratory education in science and engineering often happens in highly resource-constrained environments that compromise some of the learning objectives. This paper focuses on characterizing three…

In this paper, we investigate an approach to supporting students' learning in science through a combination of physical experimentation and virtual modeling. We present a study that utilizes a scientific inquiry framework, which we call "bifocal modeling," to link student-designed experiments and computer models in real time. In this…

Science is about asking questions but not all science courses provide students with opportunities to practice this essential skill. We give students ownership of the processes of asking and answering questions to help them take greater responsibility for their own learning and to better understand the process of science with its inherent…

This paper presents evidence of extinction, spontaneous recovery and renewal in a conditioned preferences paradigm based on taste-taste associations. More specifically, in three experiments rats exposed to a simultaneous compound of citric acid-saccharin solution showed a preference for the citric solution when the preference was measured with a…

In this communication we report on a "blended" form of assessment combining the positive aspects of a laboratory investigation, including practical skill acquisition, data reporting and social interaction, with the application and authenticity of a case study encouraging students to deepen their learning from laboratory activities. (Contains 2…

Inhibitors of fatty acid amide hydrolase (FAAH) increase endogenous levels of anandamide (a cannabinoid CB[subscript 1]-receptor ligand) and oleoylethanolamide and palmitoylethanolamide (OEA and PEA, ligands for alpha-type peroxisome proliferator-activated nuclear receptors, PPAR-alpha) when and where they are naturally released in the brain.…

The study involved the development, implementation and evaluation of laboratory audio-tutorial activities in a college chemistry course. The activities were designed in a self-instructional mode, written as linear programs and taped instructions. A pretest was used in two instances, but all included a posttest. To evaluate the effectiveness of the…
