Fluorescence-related experimental techniques play an important role in biochemistry, molecular biology, and cell biology. However, fluorescence-related experiments are rarely included in the laboratory courses of most Chinese universities. This is mainly due to the conflict between large class size (50-60 students in one room) and funding/space…

The CHIMACTIV website (http://chimactiv.agroparistech.fr/) offers open educational resources related to analytical chemistry. It addresses a frequently encountered pedagogical issue: How can we encourage students to be more involved in learning during their courses (and especially during lab work) as well as provide a deeper teacher-learner…

Hydrogen is a sustainable and climate-friendly storage for renewable energies and can directly be generated from sunlight, e.g., by photocatalytic water splitting. This article presents the photocatalytic hydrogen evolution using LED irradiation of an aqueous ZnS particle dispersion with Na[subscript 2]S and Na[subscript 2]SO[subscript 3] as…

This communicaton shares with the chemistry education community the rubrics used to evaluate student videos associated with using a pipet, using a buret, and making a solution in a volumetric flask that were part of a digital badging project. The rubrics were used across multiple general chemistry courses, hundreds of teaching assistants, and…

Based on quantitative survey data collected from an inquiry-based general chemistry laboratory course, the current study used marginal models to evaluate changes in students' teamwork and problem-solving skills, attitudes to teamwork, and willingness to explore new issues before and after the course. The results suggest that introductory-level…

A low-cost and simple setup to measure the densities of liquids is introduced herein. The results and reliability of this setup were evaluated for pure liquids, water-ethanol binary mixtures, and aqueous NaCl solutions. The constructed densitometer provided density values with acceptable relative errors (less than ±3.0%), which were compared to…

The aims of teaching laboratories is an important and ever-evolving topic of discussion amongst teaching staff at teaching institutions. It is often assumed that both teaching staff and students are implicitly aware of these aims, although this is rarely tested or measured. This assumption can lead to mismatched beliefs between students and…

The monitoring of metals in commercial products is essential for protecting public health against the hazards of metal toxicity. This article presents a guided inquiry (GI) experimental lab approach in a quantitative analysis lab class that enabled students' to determine the levels of aluminum in deodorant brands. The utility of a GI experimental…

Research-based learning motivates students to identify with different subjects. The orientation program MINTgrün at Technische Universität Berlin offers two study semesters for open choices of teaching modules, including a series of specially designed laboratories covering topics like robotics, construction, environmental research, programming,…

Students with blindness or low vision are often discouraged from full participation in laboratory science classes due to the inadequacy of current methodological approaches and the lack of sophisticated adaptive technologies. Consequently, these students rarely go on to pursue advanced studies and employment in the sciences. In response to his own…

Inadequacies of the traditional curriculum involving laboratory exercises are reviewed; general features of an integrated laboratory program are described. (DT)

Describes a grading technique for a laboratory program, designed to apprise the student each week of his performance and relative standing with peers. (SLH)

Discusses a self-paced individualized general chemistry laboratory, the Doctor of Arts program, the Educational Resources Information Center (ERIC) system, and problems existing in chemistry education. (SL)

Discussed are accidents that occur in the laboratories of highly trained chemists. Four examples are provided to illustrate potential hazards that are often overlooked in chemistry laboratories, molten inorganic salt baths, the reaction of acetone and hydrogen peroxide, halogenated acetylene compounds, and the reaction of hydrogen peroxide and…

Reviews legislation and controls in effect, and needed, to reduce the hazards of violent reactions in the uncontrolled mixing of incompatible chemicals. (SL)
