“…For example, a study has found that the effectiveness of the multimedia textbook was greater than that of the traditional printed textbook. Multimedia textbooks are similar to conventional books but differ in function in that they contain video and audio clips and animation that allow the reader to interact dynamically with the content [39,40]. In summary, to make promotional materials effective for adolescents, high-quality promotional materials which are oriented to adolescents, speak adolescents' language and include new technology elements should be designed and developed in future research.…”

Objectives This study aimed at examining the effect of the nutrition education program on adolescents' knowledge, attitudes and behaviour in relation to nutrition in rural China. Methods A cluster-randomised intervention trial design was employed. Two middle schools were randomly selected and assigned to the school conducting nutrition education (NE school), or to the Control school, in Mi Yun County, Beijing. From each school 65 seventh-grade students were randomly selected to participate in the study. Nutrition-related knowledge, attitudes and behaviour were measured at pre-and post-intervention surveys with the same instrument. The nutrition education lasted for 6 months. Results After the intervention, more students in NE school knew the main function of dairy products and vegetables, which micronutrient is rich in dairy products and beans, and in meat, and the symptom of food poisoning, than those in Control school. The rate of students who thought nutrition is very important to health, and foods with an expired date should be thrown away in NE school was higher than that in Control school (93.8 vs. 80.3 and 92.3 vs. 78.7 %, respectively). The rate of students who ate vegetables and breakfast everyday in NE school was higher than that in Control school (96.9 vs. 80.3, and 89.2 vs. 75.4 %, respectively). (p \ 0.05). Conclusions This nutrition education programme is effective in improving adolescents' knowledge, attitudes, and behaviour in relation to nutrition; therefore, the nutrition education with interactive and innovative intervention components is strongly recommended for future nutrition promotion programmes for adolescents.

“…Within this field, qualitative studies are most common, and perhaps as a consequence, there is a paucity of empirical evidence of the efficacy of e-lectures (Wofford, Spickard, & Wofford, 2001). Dewhurst and Williams (1998) concluded that the e-learning system they had implemented was as efficient as traditional means at imparting information, although a survey distributed to students found that they preferred traditional approaches to the electronic alternatives.…”

Link to record in KARThe purpose of this study was to investigate the efficacy of audio-visual synchrony in podcasting and its possible pedagogical benefits. 'Synchrony' in this study refers to the simultaneous playback of audio and video data streams, so that the transitions between presentation slides occur at ''lecturer chosen" points in the audio commentary. Manufacturers of lecture recording software (e.g. ProfCast) would have us believe that the synchrony of image and audio should improve the learning experience.We have yet to see in the literature any empirical evidence to support this hypothesis. In our study, 90 participants in two groups undertook two electronic lectures (e-lectures) on two separate topics, the subject matter of neither was familiar to them beforehand. Each group experienced one ''synchronous" presentation (electure) of one of the topics, and one ''separate" presentation (i.e. PowerPoint and audio files separately presented) of the other topic. Each group therefore experienced both ''synchronous" and ''separate" delivery and they were then given an MCQ test that assessed five levels of Bloom's taxonomy. Results show no differences in innate ability between the two groups but the evidence supported our primary hypothesis in that statistically significantly higher test scores were seen when participants viewed a synchronous electure; these scores were accounted for by subjects' performance at three of the five levels of Bloom's taxonomy. Qualitative 'attitude' survey results also displayed participant preference towards the synchronous over the asynchronous mode of delivery, and in spite of general acceptance of the proposed benefits of electronic proceedings, a majority preference towards traditional rather than electronic lectures. Despite this conservatism, this paper explores in more detail the potential benefits of podcasting via synchronous PowerPoint and voice.

“…There is evidence that delivering the audio from a lecture in combination with the presenter's slides can be an effective means of delivering lectures at remote sites, and may even be as effective as traditional lectures[3,4]. We saw this as a potential solution for providing a consistent didactic curriculum in our clerkship.…”

BackgroundMedical education is increasingly being conducted in community-based teaching sites at diverse locations, making it difficult to provide a consistent curriculum. We conducted a randomized trial to assess whether students who viewed digital lectures would perform as well on a measure of cognitive knowledge as students who viewed live lectures. Students' perceptions of the digital lecture format and their opinion as whether a digital lecture format could serve as an adequate replacement for live lectures was also assessed.MethodsStudents were randomized to either attend a lecture series at our main campus or view digital versions of the same lectures at community-based teaching sites. Both groups completed the same examination based on the lectures, and the group viewing the digital lectures completed a feedback form on the digital format.ResultsThere were no differences in performance as measured by means or average rank. Despite technical problems, the students who viewed the digital lectures overwhelmingly felt the digital lectures could replace live lectures.ConclusionsThis study provides preliminary evidence digital lectures can be a viable alternative to live lectures as a means of delivering didactic presentations in a community-based setting.
