We tracked resource and service utilizations and first-year college outcomes for the entering first-year class (n = 1,534) at a traditional 4-year postsecondary institution. We grouped specific resources and services offered by the institution
into four general categories (academic services, social resources, recreational resources, and advising sessions). We investigated
the interrelation of risk, resource and service utilization, and first-year GPA and retention. We found that utilization of
each resource/service category was positively associated with GPA and/or retention. Of particular interest, we tested whether
the associations of resource and service utilization and outcomes were moderated by risk. We found that the associations of
academic services and advising sessions with GPA were more pronounced for higher-risk students. We discuss the implications
of the findings, including how the differential associations of resource and service utilizations and outcomes can affect
intervention decisions with high-risk students.

Research-based digital games hold great potential to be effective tools in supporting next-generation science learning. However, as with all instructional materials, teachers significantly influence their implementation and contribute to their effectiveness. To more fully understand the contributions and challenges of teacher implementation of digital games, we studied the replacement of existing high school biology genetics lessons over a 3- to 6-week period with Geniverse, an immersive, game-like learning environment designed to be used in classrooms. The Geniverse materials infuse virtual experimentation in genetics with a narrative of a quest to heal a genetic disease; incorporate the topics of meiosis and protein synthesis with inheritance; and include the science practices of explanation and argumentation. The research design involved a quasi-experiment with 48 high school teachers and about 2000 students, student science content knowledge and argumentation outcome measures, and analysis using hierarchical linear modeling. Results indicate that when Geniverse was implemented as the designers intended, student learning of genetics content was significantly greater than in the comparison, business-as-usual group. However, a wide range of levels of Geniverse implementation resulted in no significant difference between the groups as a whole. Students’ abilities to engage in scientific explanation and argumentation were greater in the Geniverse group, but these differences were not statistically significant. Observation, survey, and interview data indicate a range of barriers to implementation and teacher instructional decisions that may have influenced student outcomes. Implications for the role of the teacher in the implementation of game-based instructional materials are discussed. 相似文献

Recently, attention has focused on identifying core instructional practices that could leverage novice teachers’ development of professional knowledge and skill. To help novices learn to implement these practices, there is also increasing interest in developing enactment tools that could translate abstract conceptual tasks into more concrete steps. Less attention, however, has been paid to understanding how novices might learn to use these tools adaptively in the context of practice. We address this issue by integrating a set of theoretical considerations that together serve as a model for investigating how novices could learn within a community of practice to use a specified elicitation sequence adaptively, guided by more experienced members in that community. In our results, we provide thematic categories for the problems that arose as novices used the sequence of questions and demonstrate how these problems afforded the teacher educator opportunities to connect novices’ work to a set of professional commitments that could guide their adaptive practice. In particular, we highlight how these opportunities arose in the midst of modifying the question sequence and investigating the consequences of its enactment. Although our analysis focuses on a particular question sequence, we see our results as relevant to the development of other forms of enactment tools for use in adaptive practice across a range of professional domains. 相似文献

The shortage of highly qualified graduates with advanced training in food science is a pressing problem facing government agencies and the food industry. This has created a need to recruit and train food scientists at the graduate level. However, most graduate level programs are research‐based and do not meet the needs of many students. The College of Agriculture and Life Sciences at Cornell Univ. has a Master of Professional Studies Program in Agriculture and Life Sciences (MPS‐ALS), which is offered through the Field of Food Science and Technology (FFST), as an alternative to research‐based masters and doctoral degrees. Although the MPS‐ALS program began in the 1970s, the FFST did not take an active role in recruiting students or tracking alumni until 2000. From 2000 to 2013, a total of 56 students, representing an internationally and academically diverse student body, have received MPS‐ALS degrees through the FFST. In May and August 2013, alumni were asked, via e‐mail, to complete an online survey to assess the long‐term impact of the MPS‐ALS program on their career success. The results of the survey indicate that the MPS‐ALS program at Cornell Univ. is a strong program that attracts excellent candidates from a variety of undergraduate fields. Program alumni have been very successful in obtaining full‐time employment, graduate positions and internships, and are highly satisfied with the program. The MPS‐ALS offered through the FFST at Cornell Univ. is a model for the development of course‐based graduate programs that seek to increase the supply of and meet the demand for trained professionals in food science. 相似文献

The purpose of this study was to provide an empirical basis for the interpretation of the WISC-R performance of Navajo children according to the Luria-Das Model of Simultaneous and Successive cognitive processes. Two groups of Native American Navajo subjects, 45 learning disabled and 41 gifted, were given the WISC-R. The scores on those subtests expected to involve Successive and Simultaneous processes were factor analyzed for each group and two factors were extracted. The factors, essentially similar for both samples, were interpreted to reflect the Successive and the Simultaneous modes of processing information as suggested by the Luria-Das Model. The gifted and learning disabled children had disparate loadings for some of the subtests, suggesting that the two groups may be using distinct modes of coding information. 相似文献

The forward skating start is a fundamental skill for ice hockey players, yet extremely challenging given the low traction of the ice surface. The technique for maximum skating acceleration of the body is not well understood. The aim of this study was to evaluate kinematic ice hockey skating start movement technique in relation to a skater’s skill level. A 10-camera motion capture system placed on the ice surface recorded “hybrid-V” skate start movement patterns of high and low calibre male ice hockey players (n = 7, 8, respectively). Participants’ lower body kinematics and estimated body centre of mass (CoM) movement during the first four steps were calculated. Both skate groups had similar lower body strength profiles, yet high calibre skaters achieved greater velocity; skating technique differences most likely explained the performance differences between the groups. Unlike over ground sprint start technique, skating starts showed greater concurrent hip abduction, external rotation and extension, presumably for ideal blade-to-ice push-off orientation for propulsion. Initial analysis revealed similar hip, knee and ankle joint gross movement patterns across skaters, however, further scrutiny of the data revealed that high calibre skaters achieved greater vertical CoM acceleration during each step that in turn allowed greater horizontal traction, forward propulsion, lower double-support times and, accordingly, faster starts with higher stride rates. 相似文献
