A Controlled Evaluation of a High School Biomedical Pipeline Program: Design and Methods

Given limited funding for school-based science education, non-school-based programs have been developed at colleges and universities to increase the number of students entering science- and health-related careers and address critical workforce needs. However, few evaluations of such programs have been conducted. We report the design and methods of a controlled trial to evaluate the Stanford Medical Youth Science Program’s Summer Residential Program (SRP), a 25-year-old university-based biomedical pipeline program. This 5-year matched cohort study uses an annual survey to assess educational and career outcomes among four cohorts of students who participate in the SRP and a matched comparison group of applicants who were not chosen to participate in the SRP. Matching on sociodemographic and academic background allows control for potential confounding. This design enables the testing of whether the SRP has an independent effect on educational- and career-related outcomes above and beyond the effects of other factors such as gender, ethnicity, socioeconomic background, and pre-intervention academic preparation. The results will help determine which curriculum components contribute most to successful outcomes and which students benefit most. After 4 years of follow-up, the results demonstrate high response rates from SRP participants and the comparison group with completion rates near 90 %, similar response rates by gender and ethnicity, and little attrition with each additional year of follow-up. This design and methods can potentially be replicated to evaluate and improve other biomedical pipeline programs, which are increasingly important for equipping more students for science- and health-related careers.     

Variables in Eliciting Writing Samples

What is the impact on students' writing samples of such factors as prompt features, prewriting activities, time limits, and examiner practices? How can these variables be systematically reported?     

‘Getting the pieces together’: negotiating the transition from pre-service to in-service teacher

For beginning teachers to make the transition to full professional membership they need to increase their professional knowledge of the art and science of teaching. This paper explores the difference in knowledge growth between beginning teachers who commence teaching in fragmented teaching situations in the first two years of teaching, and their colleagues who have stable, secure and continuing employment during this time. This paper argues that the employment context in which beginning teachers take up their profession has a significant, but hitherto largely unacknowledged, effect on the capacity of teachers to develop the craft of teaching (Elbaz, 1983 Elbaz, F. 1983. Teacher thinking: A study of practical knowledge, London: Croom Helm.  [Google Scholar]); on their continuing commitment to the profession; and on their self-confidence and self-image as teachers It is concluded that long-term, secure employment in one school, with full responsibility for a class of students and access to effective mentoring, is necessary if beginning teachers are to move beyond ‘survival’ to developing competency in the first two years of teaching.     

Clinical cytogenetics and molecular cytogenetics

The short report will be focused on helping our students to understand commonly used conventional and cutting edge cytogenetic techniques and their clinical applications, the advances and drawbacks of each technique, and how to pick the right test（s） for a specific patient in order to achieve a proper diagnosis efficiently and economically.     

Applying case-based method in designing self-directed online instruction: a formative research study

This study investigated the case-based method (CBM) instructional-design theory and its application in designing self-directed online instruction. The purpose of this study was to validate and refine the theory for a self-directed online instruction context. Guided by formative research methodology, this study first developed an online tutorial based on 13 design assumptions synthesized from the CBM literature. The researchers then formatively evaluated the online tutorial as a design instance of CBM through two iterations of design, evaluation, and revision. The major findings included: (1) perceived value of various CBM design features, (2) benefits and limitations of applying CBM in the tutorial design, and (3) validation and revision of a set of generic and context-specific CBM design assumptions. These findings extend our understanding of CBM to the context of self-directed online instruction and provide useful insights and practical guidance to inform instructional design practices.
