This paper presents results from a randomized experimental design replicated over four semesters that compared students’ performance in understanding landform evolution processes as measured by the pretest to posttest score growth between two treatment methods: an online interactive simulation tool and a paper-based exercise. While both methods were shown to be effective at enhancing students’ learning of the landform concepts and processes, there was no statistically significant difference in score growth between the two instructional methods. However, the attitudinal survey indicated that students consistently favored the simulation approach over the paper-based exercise. With the simulation method, female students showed greater score growth than males, especially for test items requiring higher level thinking. This indicates that the visually rich interactive simulation tool may be integrated to better support female students’ learning in geoscience. Science major students generally outperformed non-science major students in terms of score growth, which suggests that background knowledge played an important role in realizing the potential of computer modeling in enhancing students’ learning. Sufficient scaffolding is necessary to maximize the effect of interactive earth surface modeling in geoscience education.  相似文献

A quantitative analysis of campus housing figures and library usage statistics suggests a stronger correlation than library usage compared to other enrollment figures. New residents on a university campus were surveyed on their frequency and reasons for utilizing the library's physical and online resources, before and after moving in.  相似文献

Background: The approach of evidence‐based medicine (EBM), providing a paradigm to validate information sources and a process for critiquing their value, is an important platform for guiding practice. Researchers have explored the application and value of information sources in clinical practice with regard to a range of health professions; however, naturopathic practice has been overlooked. Objectives: An exploratory study of naturopaths’ perspectives of the application and value of information sources has been undertaken. Methods: Semi‐structured interviews with 12 naturopaths in current clinical practice, concerning the information sources used in clinical practice and their perceptions of these sources. Results: Thematic analysis identified differences in the application of the variety of information sources used, depending upon the perceived validity. Internet databases were viewed as highly valid. Textbooks, formal education and interpersonal interactions were judged based upon a variety of factors, whilst validation of general internet sites and manufacturers information was required prior to use. Conclusions: The findings of this study will provide preliminary aid to those responsible for supporting naturopaths’ information use and access. In particular, it may assist publishers, medical librarians and professional associations in developing strategies to expand the clinically useful information sources available to naturopaths.  相似文献

Educators are increasingly recognising the importance of improving students’ mathematics achievement. Much of the current research focuses on the impact of instructional variables on mathematics achievement. The goal of this study was to examine the influence of less researched variables – family and student factors. Participants were 747 economically disadvantaged elementary students grades K-8 in Ohio. Predictor variables included: (a) 13 factors from a parent survey on both child and family circumstances and (b) reading achievement, measured by a norm-referenced achievement test. Outcome variables included three mathematics scales from the same achievement test. Regression analyses examined the impact of the predictors on the outcomes. Reading achievement significantly predicted mathematics achievement for all three outcomes. Parent pessimism and parent-perceived school/cognitive competence of children also emerged as significant predictors for two of the three mathematics outcomes. Implications for research, policy and practice will be shared.  相似文献

In the golf instructional literature, the putting stroke is typically given higher priority than green reading and aiming. The main purpose of this study was to assess the importance of the putting stroke for direction consistency in golf putting. Kinematic stroke parameters were recorded from 71 elite golf players (mean handicap = 1.8, s = 4.2) on 1301 putts from about 4 m. Of the different factors deciding stroke direction consistency, face angle was found to be the most important (80%), followed by putter path (17%) and impact point (3%). This suggests that improvements in consistency of putter path and impact point will have very little effect on overall putting direction consistency and should not be prioritized in the training of elite players. In addition, mean stroke direction variability for an elite player (European Tour) was found to be 0.39 degrees, which is good enough to hole about 95% of all 4-m putts. In practice, however, top professionals in tournaments only hole about 17% of 4-m putts. We conclude that the putting stroke of elite golfers has a relatively minor influence on direction consistency.  相似文献
