The continuous distillation experiment in the Unit Operations Lab was moved to a virtual platform. Students used old data and equipment specifications to simulate the column in Aspen HYSYS. Students experimented without the limitations of existing equipment. For example, they studied the number of trays in the virtual column, something that is…

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…

Developing a broadly based positive culture of safety in undergraduate instructional laboratory settings remains a significant challenge for chemical educators. An enhanced safety component has been developed for an upper-level laboratory course based on earning a Chemical Hygiene and Safety badge. The badge requires student engagement in…

To enhance students' learning and help them understand the whole picture of the field of inorganic chemistry, an inorganic laboratory technique course was designed that uses scaffolded, inquiry-based lab experiments and project-based learning. The scaffolded, inquiry-based laboratories taught in the first 8 weeks of the course helped students…

The purpose of this study was to investigate the development of pre-service chemistry teachers' (PCTs') argumentation skills in a laboratory course throughout a semester. A case study design was utilised. A total of six PCTs participated in the study. To investigate the development of PCTs' argumentation skills, the laboratory reports that were in…

Potency assays of pharmaceutical products are designed to measure the amount of an active ingredient in a sample. They are important quality control tools for all medications, including intravenous (IV) admixture fluid bags which are commonly prepared by pharmacists in healthcare facilities via extemporaneous compounding. An interdisciplinary…

In many Western countries, non-formal education has become increasingly recognized as a valuable addition to the traditional educational system. In recent years, a special form of non-formal student laboratories (Schülerlabor) has emerged in Germany to promote primary and secondary practical science learning. This paper describes a developmental…

A semester-long laboratory course was designed and implemented to familiarize students with modern biochemistry and molecular biology techniques. The designed format involved active student participation, evaluation of data, and critical thinking, and guided students to become independent researchers. The first part of the course focused on…

Describes a laboratory course that introduces students to chemistry using examples commonly encountered in the supermarket and on the dinner table. Acquaints students with simple chemical tasks that can be practiced at home, including the making of wine, ale, soap, cheese, and yogurt, and introduces them to the small-scale production of…

Describes a two-hour laboratory course entitled "Chemical Periodicity offered first semester of the freshman year. Three cation groups, one anion group, and a final unkown salt are qualitatively analyzed. Course fosters scientific thinking in experimentation by encouraging student-initiated schemes of analyses rather than "cookbook schemes. (RR)

Describes the design of a new laboratory course that calls for experiments to be grouped in clusters. Each cluster has a unifying theme which gives coherence to the experiments. Other important guidelines in design were the use of computers, introduction of microscale chemistry, and use of instrumentation. Cluster examples include Carbon Is Number…

The background ideas and practical implementation that led to the use of a computer terminal in a physical chemistry laboratory are described. Outlines of two of the lab experiments being used in the program are included. (DT)

Discusses a chemical engineering course which includes laboratory experiments on polymerization, polymer fabrication, and polymer properties. (MLH)
