We have developed a wet lab DNA microarray simulation as part of a complete DNA microarray module for high school students. The wet lab simulation has been field tested with high school students in Illinois and Maryland as well as in workshops with high school teachers from across the nation. Instead of using DNA, our simulation is based on pH indicators, which offer many ideal teaching characteristics. The simulation requires no specialized equipment, is very inexpensive, is very reliable, and takes very little preparation time. Student and teacher assessment data indicate the simulation is popular with both groups, and students show significant learning gains. We include many resources with this publication, including all prelab introductory materials (e.g., a paper microarray activity), the student handouts, teachers notes, and pre- and postassessment tools. We did not test the simulation on other student populations, but based on teacher feedback, the simulation also may fit well in community college and in introductory and nonmajors' college biology curricula.  相似文献   

The employment styles of school principals recruiting beginning teachers

In New Zealand, school principals (headteachers), sometimes with a sub-committee of the school board of trustees, interview and hire their own teachers. This research examined whether school principals exhibit different styles in recruiting beginning teachers. A small group of principals was interviewed and items reflecting their views were then developed and put on cards. The cards were sorted by people familiar with educational vocabulary to enable category setting using Kirkland and Bimmler's GOPA technique. Seventy-one principals then prioritized the items. A k-means algorithm was used to cluster principals with similar responses. Analysis of the clusters suggests that recruiting styles do exist. General compatibility emerged as being most important. This suggests that having schools appoint their own staff may lead to greater diversity between schools and greater conformity within them.  相似文献
