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

Chemistry instructors in teaching laboratories provide expert modeling of techniques and cognitive processes and provide assistance to enrolled students that may be described as scaffolding interaction. Such student support is particularly essential in laboratories taught with an inquiry-based curriculum. In a teaching laboratory with a high instructor-to-student ratio, mobile devices can provide a platform for expert modeling and scaffolding during the laboratory sessions. This research study provides data collected on the effectiveness of podcasts delivered as needed in a first-semester general chemistry laboratory setting. Podcasts with audio and visual tracks covering essential laboratory techniques and central concepts that aid in experimental design or data processing were prepared and made available for students to access on an as-needed basis on iPhones® or iPod touches®. Research focused in three areas: the extent of podcast usage, the numbers and types of interactions between instructors and student laboratory teams, and student performance on graded assignments. Data analysis indicates that on average the podcast treatment laboratory teams accessed a podcast 2.86 times during the laboratory period during each week that podcasts were available. Comparison of interaction data for the lecture treatment laboratory teams and podcast treatment laboratory teams reveals that scaffolding interactions with instructors were statistically significantly fewer for teams that had podcast access rather than a pre-laboratory lecture. The implication of the results is that student laboratory teams were able to gather laboratory information more effectively when it was presented in an on-demand podcast format than in a pre-laboratory lecture format. Finally, statistical analysis of data on student performance on graded assignments indicates no significant differences between outcome measures for the treatment groups when compared as cohorts. The only statistically significant difference is between students who demonstrated a high level of class participation in the concurrent general chemistry lecture course; for this sub-group the students in the podcast treatment group earned a course average that was statistically significantly higher than those in the lecture treatment group.  相似文献

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

The present study was designed to investigate: (a) the effect of podcasts in EFL students’ oral performance, (b) the effect of podcasts in EFL students’ speaking anxiety, (c) the relationship between speaking anxiety and oral performance, and (d) EFL students’ perceptions of using podcasts. This study was conducted in a high school in Istanbul, Turkey. The students in two ninth-grade classes in the subject school were given the anxiety questionnaire, consisting of 24 items related to general foreign language class anxiety and in-class activities. A total of 30 students with the highest anxiety levels were chosen among these students. The oral performances of these students were evaluated through the Test of Spoken English and the students were also interviewed about their speaking anxiety and their oral performances. For 12 weeks, the control group followed the course book and did the speaking activities in it, while the experimental group created podcasts in addition to those activities. At the end of 12 weeks, the participants were given the anxiety post-test, the post-interview, and the oral performance post-test. The perceptions of the students in the experimental group of podcasts were examined through three interviews during the study. The results of the study showed that students who used podcasts had higher oral performance and lower speaking anxiety levels than the students who didn’t use podcast; and there was a negative relationship between the participants’ oral performances and speaking. The analysis of the interviews on podcasts revealed that the students believed podcasts helped them feel not or less anxious, and more confident; improve their oral performances and pronunciation; and expand their vocabulary.  相似文献

Student perceptions of science-oriented careers and scientists have been shown to be largely inaccurate. Through an instructional design and development process we have developed a method for offering students more accurate information about science-oriented careers. This paper follows the steps involved in developing a volume of podcast/interviews with STEM professionals and implementing the podcasts in middle level science classes. The purpose of the podcasts is to better inform middle school students about STEM career options. We present the challenges and successes of the development process as well as the efforts to create a second volume of podcasts, planned improvements and efforts for larger scale implementation, and the results from a pilot study involving the podcasts.  相似文献

Twenty‐first century students are expected to utilise emerging technologies such as lecture podcasts as learning tools. This research explored the uptake of podcasts by undergraduate students enrolled in two very different cognitively challenging subjects in the second year of the nursing programme and in the first year of a business programme. Regardless of the semester, the different content being studied and the statistically significant demographic differences between the nursing and business cohorts, striking behavioural similarities emerged. Students from both cohorts in each semester under investigation spent similar amounts of time studying regardless of gender, age, Internet access and time spent on paid work. The patterns of podcast usage by responding nursing and business students were not significantly different. Non‐listeners in both cohorts did not differ significantly from podcast users (listeners) either demographically or with regard to personal access to computers, the Internet and MP3/4 players. Non‐listeners utilised lecture notes, text resources and the learning management system in a similar way to listeners. The only significant difference was the longer hours spent in paid work by non‐listeners. These findings reinforce the emerging concept that podcasts are not embraced by everyone. Despite the flexibility and mobile learning opportunities afforded by podcasts, significant numbers of students prefer to learn in face‐to‐face environments and by reading and/or listening in set study environments.  相似文献

The versatility, intimacy and ease of production of podcasting make it a logical technology to apply to flexible education contexts. As a result, there has been increasing scholarly interest in the value of education podcasting in recent years. While education podcasting literature has tended to explore podcast implementation in institutional contexts, education podcasts outside of academia have also grown in popularity, to the extent that “education” is a common sub-group in podcast aggregation sites. This paper adapts Fernandez, Sallan and Simo’s framework of variables in education podcast design, to conduct a textual analysis of emergent design themes in non-institutional education podcasts. The findings reveal how highly successful podcasts from outside of educational institutions can both reinforce and challenge norms about education podcast design that exist within academic discourse, including in regard to podcast length, pedagogical approaches and the position of the podcast in the learning experience. It is the hope that the findings of this study might shift discourse from an interest in universalising ideas about “good practice” in education podcast design, towards more nuanced discussion of design practices that fit within specific contexts.  相似文献

The application of podcasting for educational purposes is growing fast in universities. There are several benefits of this asynchronous, direct communication and interaction between teacher and student. Nonetheless, the benefits, the pedagogical value of podcasting the traditional lecture format, have come into question. Furthermore, issues have been raised regarding lengthy and costly download times, and the fact that students need to make time to listen to them. For these reasons, using short 3–5‐minute podcasts that summarise the lecture have been suggested. This paper explores how students interact with different types of podcasts. The study compares download and course evaluation data of a series of short‐summary podcasts with full‐lecture podcasts produced for the same university course. The findings show that students value full‐lecture podcasts as highly as the short‐summary podcasts, despite the fact that full‐lecture podcasts are downloaded to a markedly lesser degree. The cause of this anomaly appears to lie in the different purposes that dictate podcast use. The paper concludes by noting that both full‐lecture and short‐summary podcasts serve as useful tools for student learning in university contexts.  相似文献

Virtual microscopy podcasts (VMPs) are narrative recordings of digital histology images. This study evaluated the outcomes of integrating the VMPs into teaching histology to osteopathic medical students. The hypothesis was that incorporating virtual microscopy podcasts as supplementary histology resources to the curriculum would have a positive impact on student performance and satisfaction. Sixty-one podcasts of dynamic microscopic images were created using screen recordings of the digital slides. The VMPs were integrated as supplementary histology resources in multiple courses during the first and second years of the medical curriculum for three classes, a total of 477 osteopathic medical students. A voluntary and anonymous survey was obtained from the students using a questionnaire that included two open-ended questions. The overall performance of the three classes on the histology content of the preclinical course examinations was compared to historical controls of the previous two classes that did not have access to the VMPs. Most students indicated that the podcasts enabled more efficient study time and improved their confidence in the histology content on examinations. The findings indicated a positive association between podcast viewing and efficient study time utilization and class performance. The class average scores of the three consecutive cohorts that used the VMPs progressively increased by 7.69%, 14.88%, and 14.91% compared to the controls. A summary of students' feedback and academic performance supported that integration of the VMPs into Histology teaching improved the learning experience. The findings align with previous studies on the effectiveness of multimedia-based teaching in histology laboratory modules.  相似文献

The purpose of this study was to examine effective ways to integrate an interactive whiteboard, podcast, and digital storytelling for language proficiency development in English language learners. Researchers integrated these three technologies into a 60-hour intensive summer English program and investigated their impacts on student vocabulary skill development. Researchers collected multiple data including daily video podcasts, vocabulary tests, a student survey, Photostory videos, and a teacher interview. The results showed that using an interactive whiteboard for (a) visual presentations, (b) interactive games, and (c) test reviews was useful for the English language learners to learn new vocabulary and engage in learning. The effects of a digital storytelling project and the video podcasts are also discussed.  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

Virtual learning environments are used in higher education around the world to promote student learning. However, in many countries it has not yielded the expected effect on student interaction and learning. The purpose of this study was to investigate whether the use of certain pedagogical approaches would promote student interaction, higher-order thinking and achievement. 102 undergraduate students taking an introductory chemistry course at a Tanzanian university participated in the study, and were randomly assigned to three groups. Each group first studied one topic using the control design (non-interactive learning, NIL) to establish a baseline. Then each group studied three further topics using different pedagogical approaches (NIL), discussion forums (medium interactive learning) and podcasts (highly interactive learning). Data included interviews, subject tests, and the content of online discussion forums. All qualitative data were coded, and repeated-measures ANOVA was used to analyze within design and between design effects; student interaction patterns were analyzed using social network analysis. Results show that social interaction, academic achievement and thinking improved progressively over the three topics (iterations) in each design. The changes in instructor pedagogical strategies and the actions of students to bring what they had learned from podcasts to the learning community contributed to the marked improvement. We conclude that effective use of discussion forums in higher education in Tanzania can produce important learning effects (interaction, thinking, and enhanced academic achievement) and is a low-bandwidth strategy, but coupling podcasts with discussion forums may be a powerful way to enhance the effects.  相似文献

A critical issue facing the field of education is the need to improve teachers' preparation to effectively manage student behavior in the classroom. Many pre- and in-service teachers receive exposure to evidence-based behavioral interventions, such as schoolwide positive behavioral interventions and supports, during teacher preparation programs; however, face-to-face instructional time is always at a premium given the range of learning experiences that must be acquired prior to licensure. Consequently, many educators begin their careers without strong classroom management skills, which has many unfortunate consequences, including the decision for some to leave the field within the first three to five years. In this study, we evaluated content acquisition podcasts based on validated instructional design principles. We focused on determining the extent to which preservice teachers could learn core information related to schoolwide positive behavioral interventions and supports using a short multimedia vignette compared to students who learned content using traditional methods (e.g., reading and note taking). Results show students who learned by watching content acquisition podcasts significantly outperformed students who had unlimited time to read a chapter on SW-PBIS and had access to other learning materials on a test of knowledge related to schoolwide positive behavioral interventions and supports. Implications for practice and future research are presented.  相似文献

Anatomists are facing a new generation of learners who will study and work in a technology-rich environment. Indeed, digital technologies are tremendously changing how information and knowledge are communicated and retrieved. However, it remains unclear whether an anatomy assessment can be designed to promote contextual learning through integrating a digital communication strategy. To investigate this, assessment methods were diversified in the first-year neuroanatomy and third-year regional anatomy curricula through implementing a multimedia human anatomy group assignment integrating digital literacies and scientific communication. Through completing this multimedia assignment, students demonstrated their anatomy knowledge transfer using a range of approaches. The main mode of presentations chosen in the two anatomy units were non-animated video presentations (~50%), animated video presentations (~30%), storyboards (~10%), podcasts (~3%), and filmed videos (~3%). A 5-point Likert scale learning and teaching survey was conducted for a total of 195 undergraduate health science students to evaluate students' perception of this group assignment. The majority of students (70–80%) strongly agreed or agreed that the multimedia group assignment helped their teamwork skills. Students who produced animated videos significantly outperformed those who adopted the non-animated presentations during the end-of-semester theory examination (p < 0.05). This study demonstrates that an anatomy group assignment integrating digital literacy and scientific communication is an effective assessment strategy associated with a positive learning experience and outcome. This inquiry-based assignment promotes learning through assessment, allowing students to not only consolidate and extend anatomy knowledge but also developing effective digital communication skills, providing new insights into non-didactic anatomy assessments.  相似文献

The purpose of this study was to examine the effect of a digitized podcast to deliver read-aloud testing accommodations on mobile devices to students with disabilities and reading difficulties. The total sample for this study included 47 middle school students with reading difficulties. Of the 47 students, 16 were identified as students with disabilities who received special education services. Participants were randomly assigned to three experimental testing conditions, standard administration, teacher-controlled read-aloud in traditional group delivery format, and student-controlled read-aloud delivered as a podcast and accessed on a mobile device, and given sample end-of-year science assessments. Based on a factorial analysis of variances, with test conditions and student status as the fixed factors, both student groups demonstrated statistically significant gains based on their testing conditions. Results support the use of podcast delivery as a viable alternative to the traditional teacher-delivered read-aloud test accommodation. Conclusions are discussed in the context of universal design for learning testing accommodations for future research and practice.  相似文献

This paper examines the experiences of undergraduate university students in response to the employment of video podcasts to support learning and teaching about exotic ecosystems. Six, 15–20‐minute podcasts were made accessible to students through a virtual learning environment, either online or to download to mobile technology. The students were free to watch the podcasts whenever and wherever they chose to. The perceived and actual effectiveness of the technology was assessed by written questionnaire, focus groups and summative assessment results. Students agreed that the podcasts were effective in supporting learning and teaching on the course, largely by offering a flexible and visual learning experience. The podcasts were also perceived as a useful resource for revision and assessment, providing visual images that stimulated factual recall and highlighted knowledge gaps. There were no significant differences, however, in examination essay grades comparing cohorts prior to and post adoption of podcasts. The key to improving the student learning experience appears to lie not in adopting new pedagogy, but in reflexively developing the existing pedagogic strategies employed by both teachers and learners. Of primary importance is uniting the individual learning experience of podcasts with group exploration and critical discussion in a collaborative learning framework.  相似文献

Abstract

The ubiquitous weekly spelling test assumes that words are best learned by memorisation and testing but is this the best way? This study compared two well-known approaches to spelling instruction, the rule based and visual memory approaches. A group of 55 seven-year-olds in two Year 3 classrooms was taught spelling in small groups for three lessons a week, 20-min per lesson, over ten weeks. In the first intervention, students learned statistically likely spelling strategies for vowel sounds, syllable breaking strategies, and the doubling rule. In the second intervention, students used a look, say, cover, write, check, fix strategy, listed words in alphabetical order, and wrote them in sentences. The control group completed non-spelling activities. Results showed that although both intervention groups learned to spell taught words better than the control group, the rule-based approach had greater transfer to spelling of new words for both proficient and less proficient spellers.  相似文献

Providing students with supplementary course materials such as audio podcasts, enhanced podcasts, video podcasts and other forms of lecture-capture video files after a lecture is now a common occurrence in many post-secondary courses. We used an online questionnaire to ask students how helpful enhanced podcasts were for a variety of course activities and how important having access to the enhanced podcasts was in their decision to miss classes. Student responses from two courses, one introductory and one advanced, were compared. Students in the introductory Genetics course reported that having access to enhanced podcasts was “very important” in their decision to miss class more often (39%) than those in the advanced Microbiology course (20%). They also reported missing more classes than students in the advanced course. Students in both courses found the enhanced podcasts helpful for a range of learning activities. First year students who missed just a few classes and those who missed many classes both found the enhanced podcasts to be very helpful for learning activities. We argue that creating these resources is a good choice for instructors irrespective of the level of the course they teach and that the potential value of these resources, particularly for first year students, outweighs any impact that having access to supplementary enhanced podcasts of the lectures may have on class attendance.  相似文献
