While active learning has shown benefits in chemistry education, there is limited application of these strategies specifically aimed at strengthening students' understanding of quality parameters in laboratory settings. This study explores the effectiveness of an educational activity based on an active learning approach to reinforce the use of…

The curriculum for undergraduate Agricultural Engineering does not usually include much laboratory practice. In order to address this, here we propose the design of a practical class on legume-rhizobia symbiosis, using an interdisciplinary approach that takes elements from botany, agriculture, and microbiology. The students perform an assay to…

Virtual experiments offer opportunities for students to engage in the scientific process and observe scientific phenomena. However, virtual experiments are not always effective for learning. The current study examined how two small manipulations might support better learning from virtual experiments and the extent to which this varied across…

Both graph comprehension and data analysis and interpretation are influenced by one's prior knowledge and experiences. To understand how one's prior knowledge and experiences interact with their analysis of a graph, we conducted think-aloud interviews with general chemistry students as they interpreted a graph to determine optimal conditions for…

To be able to design a laboratory course it is important to know what laboratory skills students possess before the course starts. This way the course can focus on developing skills in areas that are lacking. Despite the extensive literature on laboratory education, there are few studies on what laboratory skills students have at this stage of…

A study was conducted to investigate the extent to which previous science achievement affected student performance in traditional hands-on and virtual laboratory environments. A sample of 70 first-year college students was employed in a counterbalanced A-B-A-B experimental design. The study spanned four instructional weeks of laboratory…

This simple inquiry-based lab was designed to teach the principle of osmosis while also providing an experience for students to use the skills and practices commonly found in science. Students first design their own experiment using very basic equipment and supplies, which generally results in mixed, but mostly poor, outcomes. Classroom "talk…

At Miami University in Oxford, Ohio, the second-semester general chemistry course for chemistry majors is the equivalent of an analytical laboratory course. The experiments in the course are classified as classical, discovery, or instrumental on the basis of their structure and purpose. To investigate students' perceptions of learning through…

Physics teachers use experimental devices to show students how scientific concepts, principles, and laws are applied to understand the real world. This paper studies question generation of secondary and under-graduate university students when they are confronted with experimental devices in different but usual teaching situations: reading about…

Many institutions are responding to current research about how students learn science by transforming their general chemistry laboratory curricula to be inquiry-oriented. We present a comparison study of student performance after completing either a traditional or an inquiry stoichiometry experiment. This single laboratory experience was the only…

The teaching of chemistry through practical experiments has long been an established practice. It forms a key component of teaching of that subject at both school and university level and students have strong views of this method of teaching. This paper reports on the view of undergraduate level 1 chemistry students in relation to their…

The Science Writing Heuristic (SWH) is an instructional technique that combines inquiry, collaborative learning, and writing to change the nature of the chemistry laboratory for students and instructors. The SWH provides a format for students to guide their discussions, their thinking, and writing about how science activities relate to their own…
