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 experiment was conducted to assess the effect of ordinary school art instruction in human figure drawing on scores of the Goodenough-Harris Drawing Test. Subjects consisted of 44 fifth-grade students attending a suburban parochial school who were members of two preexisting, randomly assigned homeroom classes. Both classes were taught two lessons in art by their regular teachers. The treatment group was taught human figure drawing, and the control group had art lessons excluding figure drawing instruction. The Drawing Test was administered three times, one preinstruction and two postinstruction administrations. Absenteeism reduced treatment and control groups to 14 and 17 subjects, respectively. As predicted, no differences were found in the control group between pretest and postests. The treatment group showed significant gains on both posttests, as well as a significant decline from the first posttest to the second posttest. 相似文献

Aging and its effects on a person's quality of life are a growing health concern and burden for many Americans. Recently, studies have shown that adopting certain healthy behaviors may help maintain and or prevent age-related health issues such as cognitive decline. However, many people are unaware of these newfound facts. Furthermore, there is insufficient research evidence to understand how older adults view brain health and the differences between diverse groups of older adults. This study examines brain health knowledge and behaviors among Caucasian and African-American community-dwelling older adults in North Carolina. Findings were significant for level of education and total brain health knowledge scores, though there were no significant differences between races. In addition, there was a significant association between total number of health conditions and total brain health knowledge scores that warrants further study. 相似文献

The Tutoring Network is a nonprofit organization that emphasizes rigorous screening of educational therapists and careful
matching of their expertise with the needs of learning-disabled students. It operates a clearinghouse for information pertinent
to learning disabilities and strives to facilitate better communication among professionals concerned with the learning-disabled.
This paper chronicles the birth and growth of The Tutoring Network and explores possibilities for replication. 相似文献
