A highly instructive, wide-ranging laboratory project in which students study the effects of various parameters on the enzymatic activity of alcohol dehydrogenase has been adapted for the upper-division biochemistry and physical biochemistry laboratory. Our two main goals were to provide enhanced data analysis, featuring nonlinear regression, and…

The design and implementation of an advanced guided-inquiry experiment for the organic laboratory is described. Grubbs's second-generation catalyst is used to effect the ring-closing metathesis of diethyl diallylmalonate. The reaction is carried out under an inert atmosphere at room temperature and monitored by argentic TLC. The crude reaction is…

In teaching organic chemistry laboratory at this university, we eliminated the use of "canned" experiments from textbooks. Instead, we present students with literature studies that form the basis of developing new unpublished experiments to answer specific questions. In this research approach, students are better exposed to the chemical…

Sulfate reducing bacteria have been shown to be effective at treating acid mine drainage through sulfide production and subsequent precipitation of metal sulfides. In this laboratory experiment for undergraduate environmental chemistry courses, students design and implement a set of bioreactors to remediate acid mine drainage and explain observed…

This project is conducted by students during the second semester of their second year in our educational institution. This project constitutes an initiation into research and allows a broadening of knowledge, a development in autonomy, organization, team work, and initiative. It helps prepare the student-engineer for an internship in industry. The…

Method development and assessment, central components of carrying out chemical research, require problem-solving skills. This article describes a pedagogical approach for teaching these skills through the adaptation of published experiments and application of group-meeting style discussions to the curriculum of an undergraduate instrumental…

The study describes how to design and optimize an experiment with multiple factors and multiple responses. The experiment uses fractional factorial analysis as a screening experiment only to identify important instrumental factors and does not use response surface methodology to find the optimal set of conditions.

A description of the three fundamental elements of a good research story- the theoretical framework, the methodological framework and the guiding research questions- is given and the process by which the choice of theoretical framework is made is examined.

Described is a teaching method for chemistry that gives college students practice in experimental design. Students are given a problem and required to design a procedure to solve the problem. Problems increase in complexity as the students progress through the courses. (RH)

Describes a simple exercise that can be used to demonstrate the concepts of SI units, experimental design, and significant digits in a manner that holds the attention of students who already understand these concepts but is still valuable for students who are less prepared. (CCM)

Presents guidelines for supervising an undergraduate student doing research, including a sample contract set up between the student and the supervisor. The contract may state the research topic, objective, procedures, laboratory requirements, costs, schedule, additional projects, and grading criteria. Other suggestions include scheduled meetings…

Describes chemical education research conducted in classrooms using a qualitative methodology. The researcher studies interactions between learners, the teacher leading the instruction, and the material being studied in hopes of better understanding where learning occurs. This is diametrically opposed to standard experimental research, being…

Discusses some uses of questionnaires and surveys in educational research. Describes different kinds of closed and open form questions, offers suggestions for finding questionnaires for use, and describes methods of data analysis. Includes practical suggestions for using questionnaires in the chemistry classroom. (PVD)

Using questioning strategies to involve students in actually doing and analyzing experimental design can offer useful insights to instructors and students alike. Describes an interactive exploration of Alka Seltzer. (CCM)

Describes a kinetic simulation computer program that generates experimental data for use in an instructional program on the design of experiments and the analysis of results. (MLH)
