Science instructors and textbook authors often use analogies to help their students use information they already understand to develop an understanding of new concepts. This study reports the results of an analysis of the use of analogies in eight biochemistry textbooks, which included textbooks written for one‐semester survey biochemistry courses for non‐majors; two‐semester courses for chemistry or biochemistry majors; and biochemistry courses for medical school students. We present an analysis of how analogies are used and presented in biochemistry textbooks, and we compare the use of analogies in biochemistry textbooks to the use of analogies in other science textbooks. We also compare the use of analogies in biochemistry textbooks with the factors known to promote spontaneous transfer of attributes and relations from analog concept to target concept. © 2006 Wiley Periodicals, Inc.

The current study examines the effects of digital scaffolding on the English literacy of fourth- and sixth-grade students. A total of 1085 native English-speaking and language minority students from 25 treatment classes and 20 control classes across three school districts participated in this study for one school year. Treatment students read their English language arts and social studies text in visual-syntactic text format (VSTF) on their laptops and control students read the regular block format of the textbook either on their laptops or in print. Observations and interviews revealed that VSTF reading facilitated instruction processes and student learning in reading activities. The results of California Standard Tests (CST) before and after the treatment revealed that sixth-graders who received syntactic scaffolding outperformed control students on the composite CST score. In particular, reading in VSTF benefited the treatment students in three CST sub-categories: word analysis, written conventions and writing strategies. This study suggests that future research should investigate instructional strategies that support reading and writing development of adolescents, including at-risk students, using syntactic scaffolding. 相似文献

This article reports on a study of which the purpose was to understand the role of principals in changing underperforming schools towards sustainable improvement in one circuit area of North-West, South Africa. School principals play a crucial role in guiding schools towards sustainable improvement by shaping a vision of academic success for all learners. Managing teaching is one of the core modules in South Africa’s new national qualification for school principals, and that being the case, principals should play a central role in effecting the educational transformation of all learners. The quality of principals’ leadership is the key factor driving the transformational turnaround and improvement required in schools. They perform a highly complex and dynamic role in enhancing and sustaining school improvement. It was the goal of this qualitative study to explore cultural, structural, and agential challenges faced by principals in their effort to provide for change and improvement in their schools. Six schools were purposefully selected to participate in the study and semi-structured interviews were used to gather data from the principals. The study established that paying attention to cultural, structural and agential factors in schools increases their ability to sustain learner improvement. 相似文献
