The present experiments examined the effects of injecting glucose into the dorsal hippocampus or dorsolateral striatum on learning rates and on strategy selection in rats trained on a T-maze that can be solved by using either a hippocampus-sensitive place or striatum-sensitive response strategy. Percentage strategy selection on a probe trial…

In their junior or senior year, biochemistry majors at the University of Detroit Mercy are required to take a two-credit biochemistry laboratory course. Five years ago, the format of this course was changed from structured experiments to a more project-based approach. Several structured experiments were included at the beginning of the course…

For the past eight years the University of Michigan has offered two different styles of biochemistry courses each semester, one a standard lecture-based and discussion-section (SLB) course and one a self-paced, non-lecture Personalized System of Instruction (PSI) course. We tracked student responses to selected exam questions that were used in…

Professors often expect students to have the skills that are necessary to participate in discussions. Students, on the other hand, have been trained to glean information from the lecture format; their prior experiences in discussions are likely to be limited to personal opinions on topics such as stem-cell research or evolution. Sudden changes in…

Studies of protein function increasingly use multifaceted approaches that span disciplines including recombinant DNA technology, cell biology, and analytical biochemistry. These studies rely on sophisticated equipment and methodologies including confocal fluorescence microscopy, mass spectrometry, and X-ray crystallography that are beyond the…

The defining task for undergraduate departments is the design of a major, including the number and content of courses as well as other requirements. Department members must weigh the desire to produce graduates superbly prepared for further study against the charge that the major requires too large a share of an undergraduate's course options.…

Synchrony, a construct used across multiple fields to denote the temporal relationship between events, is applied to the study of parent-infant interactions and suggested as a model for intersubjectivity. Three types of timed relationships between the parent and child's affective behavior are assessed: concurrent, sequential, and organized in an…

In this report, emphasis is placed on major research developments in the reproductive sciences, their impact on the health of individuals as well as on that of society, and on current trends that may provide new opportunities for future research in fertility and infertility. In the first section, major developments in the reproductive sciences are…

Ten laboratory experiments are described which are used in a successful clinical biochemistry laboratory course (e.g. blood alcohol, glucose tolerance, plasma triglycerides, coronary risk index, gastric analysis, vitamin C and E). Most of the experiments are performed on the students themselves using simple equipment with emphasis on useful…

This master's thesis presents several instructional methods and techniques developed for each of eleven topics or subject areas in clinical chemistry: carbohydrate metabolism, lipid metabolism, diagnostic enzymology, endocrinology, toxicology, quality control, electrolytes, acid base balance, hepatic function, nonprotein nitrogenous compounds, and…

This publication is the seventh of a series of seven supplementary investigative materials for use in secondary science classes providing up-to-date research-related investigations. This unit is structured for grades 7 through 10. It is concerned with the roles of fermentation processes in the agriculture and food industry. The guide enables…

The purposes of this study were to prepare a set of four annotated articles on biochemistry from "Scientific American" and compare by means of specially-designed tests these articles with their nonannotated analogues to determine which of the two types lead to greater understanding of the contents of the latter. The population was 603 chemistry…

Factors concerning water distribution systems, including an evaluation of materials and a recommendation of materials best suited for service in typical facilities are discussed. Several installations are discussed in an effort to bring out typical features in selected applications. The following system types are included--(1) industrial…
