ABSTRACT

While textbooks serve as a primary source of content material and problem-solving practice for undergraduates in engineering, studies that investigate how engineering students prepare assignments based on textbook problems are limited. To examine how engineering students complete textbook-based assignments outside of class, this exploratory qualitative study retrospectively investigated the study behaviours of six undergraduates enrolled in a required, second-year undergraduate engineering course at a mid-size, public university in the western United States. Within the course, students solved textbook problems and electronically submitted problem answers for graded credit. Findings from in-depth, semi-structured interviews showed that students identified and used a variety of non-traditional and unsupported resources in personalised approaches to preparing assignments. Resource choice and use was affected by students’ preferences for timely support, convenience, and social connections. The online submission process seemed to influence students’ adoption of study behaviours and resources considered less effective for deep, conceptual learning.  相似文献

This study considered middle school mathematics teachers’ use of rubrics to score non‐traditional tasks. A group of eighth‐grade teachers attended a two‐day workshop where they evaluated assessment tasks and discussed the use an associated scoring rubric. Scored samples of student work submitted by the teachers indicated that they had difficulty using the rubrics for scoring. When compared to expert ratings, all except one teacher had discrepancies in scoring and some discrepancies indicated major problems. These discrepancies appear to be related to whether the task contained familiar or unfamiliar content and the mix of procedure and explanation the task required. Several other factors related to discrepancies, such as leniency errors, teacher knowledge, and the halo effect are also discussed. With the expanded use of rubrics in many arenas, these results show the need for more professional development related to rubric use.  相似文献

If the goals of science education reform are to be realized, science instruction must change across the academic spectrum, including at the collegiate level. This study examines the beliefs and teaching practices of three scientists as they designed and implemented an integrated science course for nonmajors that was designed to emphasize the nature of science. Our results indicated that, like public school teachers, scientists' beliefs about the nature of science are manifested in their enactment of curriculum—although this manifestation is clearly not a straightforward or simplistic one. Personal beliefs about the nature of science can differ from those of the course, thus resulting in an enactment that differs from original conceptions. Even when personal beliefs match those of the course, sophisticated understandings of the nature of science are not enough to ensure the straightforward translation of beliefs into practice. Mitigating factors included limited pedagogical content knowledge, difficulty in achieving integration of the scientific disciplines, and lack of opportunity and scaffolding to forge true consensus between the participating scientists. © 2003 Wiley Periodicals, Inc.

This research explored science teachers’ pedagogical discontentment and described its role in teachers’ consideration of new teaching practices. Pedagogical discontentment is an expression of the degree to which one is discontented because one’s teaching practices do not achieve one’s teaching goals. Through a series of structured interviews conducted with 18 practicing science teachers of various grade levels, content areas, routes of preparation, and amount of experience, areas of commonality in the teachers’ pedagogical discontentment were identified. The common areas of pedagogical discontentment include the ability to teach all students science, science content knowledge, balancing depth versus breath of instruction, implementing inquiry instruction, and assessing science learning. We draw implications for using this construct to craft more effective professional development.  相似文献

This article discusses librarian support of medical education programs and patient care with blogs and wikis. Pedagogical background for using Web 2.0 tools in educational settings is explored and example applications given. A survey of health sciences libraries usage of blogs and wikis was conducted in 2009-2010. Using the results from the survey plus five years of experience using blogs and wikis at the University of Washington Health Sciences Library, best practices were compiled and are presented for guidance in establishing new blogs and wikis.  相似文献

The Next Generation Science Standards support understanding of the nature of science as it is practiced and experienced in the real world through interconnected concepts to be imbedded within scientific practices and crosscutting concepts. This study explored how fourth and fifth grade elementary students’ views of nature of science change when they engage in a technology-enhanced, scientific inquiry-oriented curriculum that takes place across formal and informal settings. Results suggest that student engagement in technology-enhanced inquiry activities that occur in informal and formal settings when supported through explicit instruction focused on metacognitive and social knowledge construction can improve elementary students’ understanding of nature of science.

Understanding the interaction between internally constructed and externally imposed aspects of the teaching context may be the missing link between calls for school reform and teachers' interpretation and implementation of that reform. Although the context of the local school culture has a profound impact on teachers, there are other external forces that are specifically aimed at influencing teachers' pedagogical and curricular decisions. These externally imposed aspects of context include some of the existing tools of reform, such as national standards, mandated state core curricula, and related criterion‐referenced testing. However, little is known about how these reform tools impact teachers' thinking about science and science teaching or how teachers respond to such tools. This study examined the interactions between individual teachers' beliefs about teaching and learning science in elementary school and the tools of reform that are imposed upon them. Comparative case studies were conducted in which two elementary teachers' science instruction, teaching context, and related beliefs were examined, described, and analyzed. In this study, the teachers' fundamental beliefs about science and what it means to teach and learn science influenced their interpretations of the sometimes contradictory messages of reform as they are represented in the standards, mandated curriculum, and end‐of‐level tests. Suggestions about what these findings mean for needed aspects of teacher professional development are offered. © 2007 Wiley Periodicals, Inc. J Res Sci Teach 44: 396–423, 2007  相似文献

Comparatively little research has focussed on the experiences of disabled children in rural communities where mainstreaming may be a matter of necessity, thus providing examples of “natural experiments” in mainstreaming. A pilot study is described in which case studies are presented of five children with disabilities who attended regular schools in isolated rural communities in Queensland; a number of factors are suggested which may be associated with the outcomes of mainstreaming for these children. Several key issues in rural mainstreaming are offered as bases for hypotheses to be examined in future research programs.  相似文献

One hundred elementary‐ and middle‐school students were administered the Universal Nonverbal Intelligence Test (UNIT; B.A. Bracken & R.S. McCallum, 1998) and the Leiter International Performance Scale‐Revised (Leiter‐R; G.H. Roid & L.J. Miller, 1997). Correlations between UNIT and Leiter‐R scores were statistically significant ( p < .001), ranging from .33 to .74. The UNIT Full Scale score was 5 points higher than the Leiter‐R Full Scale score, t = 4.73, p < .001. © 2006 Wiley Periodicals, Inc. Psychol Schs 43: 143–148, 2006.  相似文献
