There is an increasing pressure on university staff to provide ever more information and resources to students. This study investigated student opinions on (audio) podcasts and (video) vodcasts and how well they met requirements and aided learning processes. Two experiments within the Aston University looked at student opinion on, and usage of, podcasts and vodcasts for a selection of their psychology lectures. Recordings were produced first using a hand‐held camcorder, and then using the in‐house media department. WebCT was used to distribute the podcasts and vodcasts, attitude questionnaires were then circulated at two time points. Overall students indicated that podcasts and vodcasts were a beneficial addition resource for learning, particularly when used in conjunction with lecturers’ slides and as a tool for revision/assessment. The online material translated into students having increased understanding of the material, which supplemented and enhanced their learning without being a substitute for traditional lectures. There is scope for the provision of portable media files to become standard practice within higher education; integrating distance and online learning with traditional approaches to improve teaching and learning. 相似文献

Lecture podcasts are considered an efficient means for passing on learning contents to students, most notably in lectures with large numbers of students. Here, the lecturer’s presentation, combined with lecture slides, is recorded and broadcasted in video form. The present study investigates how students organize learning when they have the choice of different representations of content: face-to-face lectures, lecture recordings as video podcasts, and additional text material. Latent class analysis identified three groups with different patterns of integration of these representations of content: (1) students who focused on podcasts; (2) students who made little use of the different representations of content; (3) students who occasionally made use of the different learning opportunities. Students in group 1 with a focus on podcasts achieved best. They devoted more time to learning and made diligent use of a variety of learning strategies such as note-taking, generating summaries, or rehearsing with the podcasts. The results suggest providing different representations of content to take into account differences in learners’ preferences and abilities. They speak in favor of podcasts, especially in lectures with a large audience. However, the results also show a group of learners who make minimal use of the various representations of content. Instructional measures should be taken to engage and support these students. 相似文献

Abstract Lectures remain the primary method of instruction in higher education despite several limitations: Students typically lose interest during hour-long lectures, lectures lead to rote learning by some students, and lectures do not lead to development of higher-level conceptual thinking skills. As an alternative to a lecture on the topic, an active learning exercise was developed to teach students about nonverbal communication. The exercise was used with several classes, and students reported it was motivating, educational, and thought-provoking. Advantages of implementing active learning exercises in lecture courses are discussed. 相似文献

当前使用的大多数电子学习材料都是基于对多数学生面授辅导的讲稿,而没有把学习者的不同情况考虑在内。有的学习者没有与教师直接或非直接接触的途径。还有一些印刷材料,因为通过视频授课而使质量有所提升。此外,许多电子学习材料所使用的图示和例子与现实情况毫无关联。有时,电子材料中会有动态模拟器,但是许多动态模拟器既不能激励学生学习,也不能激发学生的学习兴趣。尤其在工程科学领域,这种方法是有缺陷的。工程学是理论知识和实践经验的结合,实践经验是处理复杂系统的行为活动。在传统教学中,这种经验是在实验室中获得。而对于远程教学,到目前为止,在教学中融入实验有两种选择：学生使用真实实验室或是进行模拟实验。前者需要花费时间和金钱;后者却缺少对系统的真实“感觉”。本文介绍的项目有助于克服在远程教学中存在的一些缺陷。本文描述的新方法是建立在理论文本、视频、动画、模拟器和远距离使用真实实验室的密切联系之上。用于实验的技术系统选取工业厂房的典型部分。五个真实实验室已经建立起来,全部通过互联网向学生开放。这些实验室使得用户能够深化对培训教材理论的理解,并且能够利用实际应用测试用户知识,这些不需要用户去工业厂房就可以实现。这些实验室都经过仔细挑选,可以精确解释理论课程的内容,其难度与用户实际需要相适应。尽管用户无法进入实验室,但是他们有合适的工具支持,可以获取完成任务所需要的所有信息。 相似文献

The lectures for two modules which together comprise an introductory course on textiles and textile manufacturing comprising some 70 hours of lectures were replaced by computer-based multimedia learning material requiring a similar amount of study time. In a student project the reactions and attitudes of students to taking the computer-based course were elicited through two questionnaires. The results of the student project indicated that the data was worthy of further study, in particular, the responses to the second questionnaire. In this paper these data are analysed in detail. The attitudes and reactions of the students are linked to features of the material and its use, and to possible more general attitudes of the students. Consideration is given to the study behaviour of the students and ways in which the courseware might be improved are proposed. 相似文献

Podcasting in higher education: What are the implications for teaching and learning? 总被引：1，自引：0，他引：1
A podcast is any digital media file, or series of files, distributed over the Internet for playback on portable media players and personal computers. This study explored the attitudes, perceptions, and use of podcasting as reported by instructors and students at a large American Midwestern university. The results of two online surveys were examined, focusing specifically on items related to teaching and learning. Findings suggest that students use podcast materials largely for reviewing concepts and issues raised in lectures that they have previously attended. While instructors and students agree that podcasts help students learn, students are less sure about whether podcasts improve instructors' teaching. The authors argue that podcasts can help instructors change face-to-face instruction from traditional didactic lectures to more constructivist learning practices. 相似文献

Although multiple choice examinations are often used to test anatomical knowledge, these often forgo the use of images in favor of text‐based questions and answers. Because anatomy is reliant on visual resources, examinations using images should be used when appropriate. This study was a retrospective analysis of examination items that were text based compared to the same questions when a reference image was included with the question stem. Item difficulty and discrimination were analyzed for 15 multiple choice items given across two different examinations in two sections of an undergraduate anatomy course. Results showed that there were some differences item difficulty but these were not consistent to either text items or items with reference images. Differences in difficulty were mainly attributable to one group of students performing better overall on the examinations. There were no significant differences for item discrimination for any of the analyzed items. This implies that reference images do not significantly alter the item statistics, however this does not indicate if these images were helpful to the students when answering the questions. Care should be taken by question writers to analyze item statistics when making changes to multiple choice questions, including ones that are included for the perceived benefit of the students.

A number of factors can influence learning from lectures such as students' prior knowledge, their motivation, the instructional design, the lecturer and so forth. Instructional aid techniques such as preparing class notes, giving quizzes (either planned or spot quizzes) and the like can be used to maximise learning. This study uses two well‐documented tools for learning from text—advance organisers and higher order questions—adapted for use with podcasts. Student evaluations of their experience of being primed for lectures with podcasts are described. The findings show that audio advance organisers and questions experienced by students have a positive influence on learning, because they help students bridge the conceptual distance between new and prior knowledge, better understand the topics in the lectures and stimulate thinking more deeply about the lecture's content and the possible applications of the subject of the lecture. 相似文献

Four experiments examined the utility of real-time text in supporting deaf students' learning from lectures in postsecondary (Experiments 1 and 2) and secondary classrooms (Experiments 3 and 4). Experiment 1 compared the effects on learning of sign language interpreting, real-time text (C-Print), and both. Real-time text alone led to significantly higher performance by deaf students than the other two conditions, but performance by deaf students in all conditions was significantly below that of hearing peers who saw lectures without any support services. Experiment 2 compared interpreting and two forms of real-time text, C-Print and Communication Access Real-Time Translation, at immediate testing and after a 1-week delay (with study notes). No significant differences among support services were obtained at either testing. Experiment 3 also failed to reveal significant effects at immediate or delayed testing in a comparison of real-time text, direct (signed) instruction, and both. Experiment 4 found no significant differences between interpreting and interpreting plus real-time text on the learning of either new words or the content of television programs. Alternative accounts of the observed pattern of results are considered, but it is concluded that neither sign language interpreting nor real-time text have any inherent, generalized advantage over the other in supporting deaf students in secondary or postsecondary settings. Providing deaf students with both services simultaneously does not appear to provide any generalized benefit, at least for the kinds of materials utilized here. 相似文献

Videos of classroom lectures have proven to be a popular and versatile learning resource. A key shortcoming of the lecture video format is accessing the content of interest hidden in a video. This work meets this challenge with an advanced video framework featuring topical indexing, search, and captioning (ICS videos). Standard optical character recognition (OCR) technology was enhanced with image transformations for extraction of text from video frames to support indexing and search. The images and text on video frames is analyzed to divide lecture videos into topical segments. The ICS video player integrates indexing, search, and captioning in video playback providing instant access to the content of interest. This video framework has been used by more than 70 courses in a variety of STEM disciplines and assessed by more than 4000 students. Results presented from the surveys demonstrate the value of the videos as a learning resource and the role played by videos in a students learning process. Survey results also establish the value of indexing and search features in a video platform for education. This paper reports on the development and evaluation of ICS videos framework and over 5 years of usage experience in several STEM courses. 相似文献

The purpose of this investigation was to determine the effects of using laboratory photomicrography as a motivational technique in the teaching-learning processes involved in the study of microbiology in Nigerian secondary schools. This was done by comparing the posttest scores and the questionnaire responses made by three equal groups of randomly sampled and assigned students taught the same microbiology content material by lectures and photomicrography used as an adjunct to the laboratory, lectures, and laboratory activities and lectures alone. Each group was taught by a different microbiology teacher. The results of this study, as shown in Tables I through V permitted the conclusion that students taught microbiology by lectures with photomicrography activities achieved the highest posttest mean score and expressed the opinion that they were highly motivated by this teaching method. Students taught microbiology by lectures with laboratory activities achieved lower mean posttest score and expressed the opinion that they were only fairly motivated by this teaching approach. Students taught microbiology by lectures alone achieved the lowest mean posttest score and expressed the opinion that they were least motivated by this teaching approach. 相似文献

An innovative collaborative learning model, used for the teaching of modern English grammar classes, combined elements from peer teaching and cooperative learning. This model is innovative for higher education since it involved students and instructor co-laboring to master knowledge as a socially held phenomenon without any authoritarian leveling. It involved: 1) Student lectures explaining assigned readings from the text(s); 2) Daily quizzes of the material from the assigned reading; and 3) Student grading of the daily quizzes and exams with the instructor checking for accuracy. Student attitudinal surveys revealed positive perceptions of students on the whole toward the conduct of the class. An even greater positive aspect of the collaborative learning model used here is the attainment of a high level of mastery of the subject matter and almost perfect classroom attendance.He obtained his Ed.D. at the University of Michigan in 1963. His major areas of interest include the teaching of written composition and TESL. 相似文献

The present research examined the effect of illustrations on readers' metacomprehension accuracy for expository science text. In two experiments, students read non-illustrated texts, or the same texts illustrated with either conceptual or decorative images; were asked to judge how well they understood each text; and then took tests for each topic. Metacomprehension accuracy was computed as the intra-individual correlation between judgments and inference test performance. Results from both studies showed that the presence of decorative images can lead to poor metacomprehension accuracy. In the second study, an analysis of the cues that students reported using to make their judgments revealed that students who used comprehension-relevant cues showed more accurate metacomprehension. A self-explanation instruction did not alter either comprehension-relevant cue use or metacomprehension accuracy, although some advantages were seen when readers were prompted to self-explain from texts illustrated with conceptual images. These results suggest that students may need more explicit instruction or support to promote the use of valid cues when engaging in comprehension monitoring with illustrated text, and that seductive information such as decorative images may undermine comprehension monitoring. 相似文献

This paper reports on the findings of a study investigating students' perceptions of lectures, seminars and modules in a university school of sociology and social policy. An anonymous questionnaire was used which incorporated both closed and open-ended questions. Results show that students thought lectures were well structured and audible, the latter being linked to easy note-taking. Lecturers were also viewed as enthusiastic and available for discussion and a good student-teacher rapport was reported. On the other hand, students had difficulties with overhead transparencies and the speed at which some lectures were presented. Seminars were reported to be well organised and integrated with lectures but students were less enthusiastic about the modular system, although they felt that module objectives were clear. Students were most dissatisfied with availability of books in the library. The paper ends by presenting some suggestions for future studies. 相似文献

Many college students seem to find it impossible to resist the temptation to text on electronic devices during class lectures and discussions. One common response of college professors is to yield to the inevitable and try to ignore student texting. However, research indicates that because of limited cognitive capacities, even simple texting can reduce comprehension of class material at a rate of 10–20%. We review that research and present our study of the effects of texting on comprehension. Proposed alternatives to ignoring texting or outright bans include using smartphones for classroom exercises, educating students about the dangers of multitasking, and the use of “technology breaks.” 相似文献

This paper is based on the experience acquired in teaching materials science/engineering to first year university students. It has been observed that students struggle with some of the fundamental materials concepts addressed in the module/course. This applies to delivered lectures but extends to the incorporation of tutorial sessions provided after lectures. Moreover, when students miss a lecture or seminar the acquisition and application of knowledge and concepts becomes problematic. Consequently, or perhaps inevitably, these students perform poorly in their assessments and their motivation for the subject suffers. A careful analysis of this situation and of the nature of interaction and engagement was performed to gain an insight into the reasons for this lack of performance. A common factor is that students do not dedicate sufficient time for reading and consolidation using the chapters/sections prescribed after each topic. They also do not attempt solving tutorial problems outside the formal contact hours. This reflection and personal evaluation is difficult to administer, resource intensive and yet potentially enables each student to monitor and evaluate their own learning and understanding. A multimedia learning technology‐based environment was created in which students could engage. This was located within the University of Wolverhampton Virtual Learning Environment (VLE) called WOLF. The students were able to progress independently but with access to tutor and peer support, help and advice. The use of non‐text animations and structures was used and seen as fundamental by the students in enhancing the taught course and in developing a deeper understanding of complex atomic and crystal structures. 相似文献
