Whether through the use of online-only or hybrid/blended formats, colleges and universities across the country are increasingly utilizing online platforms as a medium for the delivery of instruction. At the same time, we know little about how student learning outcomes are related to students’ engagement with online instructional formats. In particular, few studies have evaluated online learning in community colleges, and fewer yet have employed an experimental or quasi-experimental design to do so. In this research, we use propensity score matching to compare learning gains between community college students enrolled in blended courses, (courses that combine online instructional delivery with traditional classroom-based instruction) with gains experienced by students receiving only classroom-based instruction. Among students enrolled in blended courses, we also consider which aspects of student use of online instructional materials are most strongly associated with student learning. While some evidence has suggested significantly poorer outcomes for community college students enrolled in online-only courses, our results suggest that students enrolled in blended courses perform similarly, if not better, relative to students in a traditional instructional setting. Implications for practice and research are discussed.  相似文献

Two experiments are presented that examine how the visual characteristics of Japanese words influence eye movement behaviour during reading. In Experiment 1, reading behaviour was compared for words comprising either one or two kanji characters. The one-character words were significantly less likely to be fixated on first-pass, and had significantly longer overall reading times, than the two-character words. In Experiment 2, reading behaviour was compared for two-kanji character words, for which the first character was either visually simple or visually complex (determined by the number of strokes). Visual complexity significantly influenced total word reading times and the probability of the individual visually simple/complex characters being fixated on first pass. Additional analyses showed no preferred viewing position for two-kanji character words. Overall, the study provides experimental evidence of an influence of specific visual characteristics of Japanese words on eye movement behaviour during reading, as shown by both fixation probabilities and reading times. The findings must be explained by processing at (or beyond) a visual level impacting on eye movement behavior during reading of Japanese text.  相似文献

The literature on the pedagogical aspects of the photoelectric effect as used in the undergraduate student laboratory shows that little research has been done in this area. Our current study is an analysis of the instructions in 38, electronically published laboratory manuals for the photoelectric effect. The analyses were based on history and philosophy of science criteria that we had developed for evaluating the presentation of the photoelectric effect in introductory, university-physics textbooks. The results show that writers of laboratory instructions do not pay sufficient attention to the relevant background for the photoelectric effect. In our study, none of the instructions achieved a score of excellent, only 5% were scored as satisfactory, and only 7% mentioned the various aspects contained in our criteria. These results for our analysis of laboratory instructions are significantly less favorable than those achieved for physics textbooks in our previous study. Based on our work, we recommend that several historical aspects be included in all laboratory instructions for the photoelectric effect.  相似文献

Although song and music are often elements in children's books, little critical attention has gone into examining their literary uses. Alan Garner's The Stone Book Quartetis an example of four texts for children in which music plays a vital role. The several snatches of traditional songs found throughout the quartet bring to life the culture of the characters but also are tied to the conflicts that occur within the stories. An exploration of Garner's use of song uncovers the underlying theme of the book—the necessity of balance in our lives.  相似文献

Co-rumination in the friendships of girls and boys   总被引:1,自引:0,他引:1  
Rose AJ 《Child development》2002,73(6):1830-1843
This research addresses a new construct, co-rumination. Co-rumination refers to extensively discussing and revisiting problems, speculating about problems, and focusing on negative feelings. Friendship research indicates that self-disclosure leads to close relationships; however, coping research indicates that dwelling on negative topics leads to emotional difficulties. Co-rumination is a single construct that integrates both perspectives and is proposed to be related both to positive friendship adjustment and problematic emotional adjustment. Third-, fifth-, seventh-, and ninth-grade participants (N = 608) responded to questionnaires, including a new measure of co-rumination. Co-rumination was related to high-quality, close friendships and aspects of depression and anxiety. Girls reported co-ruminating more than did boys, which helped to account for girls' more positive friendship adjustment and greater internalizing symptoms. Other analyses addressed whether co-rumination and the related constructs of self-disclosure and rumination had different relations with friendship and emotional adjustment.  相似文献

Students undertaking a final year elective subject in transportation planning at Monash University in Melbourne, Australia, worked on a practical project for which there was an interested outside 'client'. From the students' perspective, this was essentially a 'simulated' consulting project which focused on transport planning issues faced by an inner metropolitan municipality in Melbourne. The overall experience, from everybody's perspective, proved to be so positive that the model for the project will be used in the course in future years. This paper has been written to inform engineering educators of how the project was implemented and to highlight some of the educational issues which this type of experience raised. Of particular interest to educators are issues associated with the functioning of some of the student groups and the opportunities provided by projects of this nature to establish strong links with industry.  相似文献

The distinction between intrinsic and extrinsic goals, and between goal pursuit for intrinsically and extrinsically motivated reasons, is a central premise of self-determination theory. Proponents of the theory have proposed that the pursuit of intrinsic goals and intrinsically motivated goal striving each predict adaptive psychological and behavioral outcomes relative to the pursuit of extrinsic goals and extrinsically motivated goal striving. Despite evidence to support these predictions, research has not explored whether individuals naturally differentiate between intrinsic and extrinsic goals. Two studies tested whether people make this differentiation when recalling goals for leisure-time physical activity. Using memory-recall methods, participants in Study 1 were asked to freely generate physical activity goals. A subsample (N = 43) was asked to code their freely generated goals as intrinsic or extrinsic. In Study 2, participants were asked to recall intrinsic and extrinsic goals after making a decision regarding their future physical activity. Results of these studies revealed that individuals' goal generation and recall exhibited significant clustering by goal type. Participants encountered some difficulties when explicitly coding goals. Findings support self-determination theory and indicate that individuals discriminate between intrinsic and extrinsic goals.  相似文献

The premature sexualisation of young people is a source of intense public anxiety, often framed as an unprecedented crisis. Concurrently, a critical scholarship highlights problematic assumptions underpinning this discourse, including a positioning of young people as morally compromised passive subjects, and a disconnect between the reductionist framework and the complexity of young peoples’ lived experiences. Drawing from ethnographic research in a London school, in this article I argue that by attending to the everyday lives of pupils, a more nuanced picture of moral and sexual change and continuity emerges. Using the framework of ‘ordinary ethics’, which identifies ethics as pervasive in speech and action, I demonstrate the multiple ways by which young people define and act according to what they consider sexually good and right. In this way the analytical focus is shifted from passivity to activity and we can appreciate how young people today are evincing a sexual ethics of force and efficacy.  相似文献
