A new role for the clinical librarian as educator

The Clinical Medical Librarian (CML) Program of the Tompkins-McCaw Library is a special instructional initiative to teach third-year medical students the use of information resources in the clinical setting. Librarians spend one week with selected internal medicine teams participating in work rounds and instructing team members in the use of the medical literature. The librarian assists team members to identify and retrieve relevant information through computer workstations located in the hospital. Photocopies of journal articles are made available to team members through the CML document delivery program.     

Successful and unsuccessful problem solving in classical genetic pedigrees

Using the think-aloud interview technique, 16 undergraduates and 11 genetics graduate students and biology faculty members were asked to solve from 1 to 3 classical genetics problems which require pedigree analysis. Subjects were classified as either successful or unsuccessful and the performances of these groups were analyzed from videotaped recordings of the interviews. A number of previously reported findings were corroborated. Additional observations are discussed in terms of genetic knowledge, use of production rules, strategy selection, use of critical cues, hypothesis testing, use of logic, understanding of issues of probability, and the thinking process itself. Taken collectively, these findings evidence a remarkable similarity between the successful solution of pedigree problems and the processes of medical diagnosis and scientific investigation. This convergence of research findings suggests a qualitative advance in the understanding of problem solving. Based on this understanding, recommendations for classroom instruction are presented.     

Follow-up of postsecondary-age rural learning disabled graduates and dropouts

This article reports the dropout rates, basic skills competency levels, and employment status of a group of semi-rural learning disabled postsecondary-age youth and a control group of nonlearning disabled same-age peers. Findings indicated significantly higher dropout rates and significantly lower basic skills competency levels among learning disabled youth. Learning disabled graduates and dropouts were not different in how they fared in the employment market for the group, nor were they different compared to peers. Educational implications of these findings and future suggestions for follow-up research are discussed.     

Teaching and Learning in STEM Enrichment Spaces: From Doing Math to Thinking Mathematically

Science, technology, engineering, and mathematics (STEM) enrichment programs can meet the needs of gifted students by providing an intellectual challenge, a motivated peer group, and skilled teachers. In the Saturday Enrichment Program (SEP), 40 students (Grades 4–8) explored challenging math topics not typically taught in their schools. Pre and post questionnaires, video documentation of classes, and field notes indicated that students were less interested in the content of their school math classes after participation in SEP. They also reported that SEP provided a more appropriate pace, challenge, and fun. Analysis of classroom videos revealed four major strategies teachers utilized: (a) fostering of a supportive and collaborative environment, (b) developing the identity of a mathematician, (c) open-ended questions for conceptual exploration, and (d) discovery through play.     

The evolution of diesel engines

Rudolf Diesel thought of an engine which is inherently more efficient than the steam engines of the end-nineteenth century, for providing motive power in a distributed way. His intense perseverance, spread over a decade, led to the engines of today which bear his name.
