Spontaneous focusing on quantitative relations (SFOR) has been shown to be a strong predictor of rational number conceptual development in late primary school. The present study outlines an intervention program that examines the possibilities to enhance late primary school students' SFOR tendency. The intervention program harnessed mobile technology in order to allow students to explore and identify quantitative relations in their everyday environment, including situations outside of the classroom. A total of 38 thirteen-year-olds from two classrooms participated in the seven-week long quasi-experimental study. One classroom spent five lessons over five weeks participating in activities which involved uncovering, defining and describing multiplicative relations in their everyday surroundings. In comparison to a business-as-usual control group, results show the intervention to be successful in enhancing SFOR tendency. These results suggest that it is possible to utilize mobile technologies to enhance students' awareness of the possibilities to use quantitative relations as explicit targets of focusing and reasoning in nonexplicitly mathematical situations. 相似文献

This study aimed to test the validity of a non-motorised treadmill (NMT) for the measurement of self-paced overground endurance running performance. Ten male runners performed randomised 5-km running time trials on a NMT and an outdoor athletics track. A range of physiological and perceptual responses was measured, and foot strike was classified subjectively. Performance time was strongly correlated (r = 0.82, ICC = 0.86) between running modes, despite running time being significantly longer on the NMT (1264 ± 124 s vs. 1536 ± 130 s for overground and NMT, respectively; P < 0.001). End blood lactate concentration and rating of perceived exertion were significantly higher on the NMT compared to overground. Integrated electromyography was significantly lower on the NMT for three muscles (P < 0.05), and mean stride rate was also significantly lower on the NMT (P = 0.04). Cardiorespiratory responses of heart rate, oxygen uptake and expired air volume demonstrated strong correlations (r = 0.68–0.96, ICC = 0.75–0.97) and no statistical differences (P > 0.05). Runners were consistently slower on the NMT, and as such it should not be used to measure performance over a specific distance. However, the strong correlations suggest that superior overground performance was reflected in relative terms on the NMT, and therefore, it is a valid tool for the assessment of endurance running performance in the laboratory. 相似文献

The purpose of this study is to enhance our understanding of how college students connect online prior to their first year. Before students ever set foot on a college campus, they are making friends, joining clubs, locating activities, finding roommates and discussing future student activities all through the social network site, Facebook. Anticipatory socialisation theory frames this research to focus on the social, academic and career aspects of the transition. A case study approach and content analysis methodology sought to better understand frequent topics and themes for pre-college students. The primary foci of the pre-college Facebook interactions were connectivity and commonality among new students. An unintended finding was the discovery of crowdsourcing on post-secondary social media sites. Crowdsourcing taps into the collective intelligence of the public to complete tasks that an organisation would normally either perform itself or contract to a third-party provider; hence, outsourcing to a crowd. In this case, the crowd is comprised of pre-college students about to start their first year of post-secondary education. 相似文献

The current study examined the relations among key variables that underlie reading comprehension of expository science texts in a diverse population of adult native English readers. Using Mechanical Turk to sample a range of adult readers, the study also examined the effect of text presentation on readers’ comprehension and knowledge structure established after reading. In Study 1, ratings of situational interest, select reading background variables, and select measures of readers’ knowledge structure accounted for significant variance in comprehension. In Study 2, the knowledge structure metrics of primacy, recency, and node degree as well as several text ratings were found to be comparable across text presentation formats. Participants who read the text sentence-by-sentence obtained higher scores on measures of comprehension and provided higher ratings of situational interest than those who received the whole paragraph text at once. Knowledge structure measures for the sentence-by-sentence and paragraph formats were similar (68% overlap). We discuss implications for future research examining factors that underlie the successful comprehension of science texts. 相似文献

This study used two successive phases of usability testing to evaluate two different versions of a Communication 430 course LibGuide. The first version of this guide had a longer, more visually complex navigation menu, with more course-related research information directly accessible through this menu. The second version had a shorter, less complex menu that offered less directly accessible information. Twenty-four of the 33 students enrolled in the class (73%) tested either one version or the other for usability in completing tasks that simulate course-related research assignments, ultimately indicating they found the longer navigation menu more usable. This paper may be the first to describe the engagement of students enrolled in a course in testing a LibGuide dedicated specifically to that course. As such, it will be of interest to many academic librarians and instructional design professionals. 相似文献

This paper reports a content analysis of 778 television commercials. Commercials were examined for the presence of older adults. Commercials featuring older adults were then examined more closely to describe the nature of the portrayals. Consistent with previous research, older adults were shown to be underrepresented in the commercials examined, as compared to their presence in the population. This effect was particularly strong for older women and for members of ethnic minorities. However, older adults were found to be presented in a relatively positive light—as active, happy, and strong. In addition, older adults were shown to be least underrepresented in advertisements for financial services and retail chains, and most underrepresented in advertisements for automobiles and travel services. The results are discussed in terms of the changing position of the older adult consumer in the marketplace. Suggestions for future research are provided. 相似文献

We examine connections between media use, intergroup contact, and acculturation in 237 Asian Indian professionals in Silicon Valley, drawing on theories of immigrant acculturation, intergroup contact, and media effects. Quality of host contact positively predicted acculturation. Indian (ethnic) media consumption negatively predicted acculturation, and American (host) media consumption was positively related to acculturation. Ethnic television viewing exacerbated the effects of negative intergroup contact on acculturation. Respondents used social networking websites to maintain both host and ethnic ties. Host cultural/informational capital was positively related to acculturation. Host media consumption was positively related to political engagement and loneliness. 相似文献

Despite the recent technical and theoretical advances in the investigation of children's social relations, the inherent complexity of these methods may prevent their easy integration into the classroom. A simple and effective tool can be valuable for teachers who wish to investigate students' social realities in the classroom. Therefore, the present study aims to identify an effective sociometric method for educator's use in the classroom. Nine separate sociometric categorisations were created from peer reports of grade one students (N = 748). Methods that have different collection methods (nominations or ratings) show surprisingly low agreement, unlike those with the same collection method. Methods based on peer nominations showed the strongest correlations with students' behavioural traits. Based on these results, we discuss the relevance and usefulness of such methods for use by classroom teachers in identifying students' social realities. 相似文献
