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

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

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 study investigated the impact of podcasts and vodcasts accessed through an iPod on fourth- and sixth-grade students’ vocabulary acquisition. Students were randomly assigned to either a podcast group or a vodcast group. Regardless of group assignment, each student completed three six-minute podcasts or vodcasts a day for three days. On average, students learned four out of nine words taught regardless of group assignment. The vodcast group learned significantly more words compared to the podcast group at the receptive level and at the expressive level. Student comments indicated that iPods should be used to teach and to review words.  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

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 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 study uses an action research approach to investigate how different modes of pre-laboratory preparation contribute towards a fruitful laboratory experience for first year students on an access programme. We considered the experience to be fruitful if the students successfully acquired procedural understanding, communicative competence and were able to apply the conceptual understanding to make the purpose of the labs meaningful. A group of students was observed by participant observers during 1996. Data was gathered during laboratory sessions and from written pre-laboratory work. These data were analysed and changes were instituted in the running and conceptualization of the laboratory in the subsequent year. A group of students was again observed and data collected. Two important factors emerged from the analysis of the data. One finding was the importance of adequate student preparation for the laboratories, regardless of the mode of preparation employed. Another was that the ability to prepare depended on the conceptual and procedural understanding of the laboratory as a whole. Preparedness is also important if conceptual benefit is to be obtained from the practical experience.  相似文献

The flipped classroom pedagogy was implemented in two core undergraduate science courses; Animal and Plant Biochemistry II (APB) and Microbiology and Invertebrate Biology II (MIB) to encourage students to prepare for laboratory classes. Students often attend class without little understanding or appreciation of what they are going to learn in the laboratory, the types of techniques they are going to use or the safety precautions required. This is not only hazardous for students but also requires detailed explanations from teaching staff at the start of class, overloading students with information. This disconnection between theory and practice was overcome by ‘flipping the laboratory’ to integrate online, interactive pre-laboratory activities into the curriculum. The aims of this study were to: (1) evaluate student engagement with pre-laboratory content; (2) investigate student performance and learning outcomes; (3) review failure rates following implementation of pre-laboratory activities. Students agreed that the pre-laboratory activities bridged the gap between theory and practice (65%) and enhanced their engagement with course material (79%). The integration of pre-laboratory activities significantly increased student learning outcomes immediately after implementation into the curriculum, despite a 26.8% increase in enrolments from 2011 to 2017. Failure rates significantly decreased in both APB and MIB over three consecutive years.  相似文献

Video and photography are often used for delivering content within the anatomical sciences. However, instructors typically produce these resources to provide instructional or procedural information. Although the benefits of learner‐generated content have been explored within educational research, virtually no studies have investigated the use of learner‐generated video and photograph content within anatomy dissection laboratories. This study outlines an activity involving learner‐generated video diaries and learner‐generated photograph assignments produced during anatomy laboratory sessions. The learner‐generated photographs and videos provided instructors with a means of formative assessment and allowed instructors to identify evidence of collaborative behavior in the laboratory. Student questionnaires (n = 21) and interviews (n = 5), as well as in‐class observations, were conducted to examine student perspectives on the laboratory activities. The quantitative and qualitative data were examined using the framework of activity theory to identify contradictions between student expectations of, and engagement with, the activity and the actual experiences of the students. Results indicate that learner‐generated photograph and video content can act as a rich source of data on student learning processes and can be used for formative assessment, for observing collaborative behavior, and as a starting point for class discussions. This study stresses the idea that technology choice for activities must align with instructional goals. This research also highlights the utility of activity theory as a framework for assessing classroom and laboratory activities, demonstrating that this approach can guide the development of laboratory activities.

Digitally simulated laboratory assessments (DSLAs) may be used to measure competencies such as problem solving and scientific inquiry because they provide an environment that allows the process of learning to be captured. These assessments provide many benefits that are superior to traditional hands-on laboratory tasks; as such, it is important to investigate different ways to maximize the potential of DSLAs in increasing student learning. This study investigated two enhancements—a pre-laboratory activity (PLA) and a learning error intervention (LEI)—that are hypothesized to enhance the use of DSLAs as an educational tool. The results indicate students who were administered the PLA reported statistically lower levels of test anxiety when compared to their peers who did not receive the activity. Furthermore, students who received the LEI scored statistically higher scores on the more difficult problems administered during and after the DSLA. These findings provide preliminary evidence that both a PLA and LEI may be beneficial in improving students’ performance on a DSLA. Understanding the benefits of these enhancements may help educators better utilize DSLAs in the classroom to improve student science achievement.

Writing assignments, including note taking and written recall, should enhance retention of knowledge, whereas analytical writing tasks with metacognitive aspects should enhance higher-order thinking. In this study, we assessed how certain writing-intensive “interventions,” such as written exam corrections and peer-reviewed writing assignments using Calibrated Peer Review and including a metacognitive component, improve student learning. We designed and tested the possible benefits of these approaches using control and experimental variables across and between our three-section introductory biology course. Based on assessment, students who corrected exam questions showed significant improvement on postexam assessment compared with their nonparticipating peers. Differences were also observed between students participating in written and discussion-based exercises. Students with low ACT scores benefited equally from written and discussion-based exam corrections, whereas students with midrange to high ACT scores benefited more from written than discussion-based exam corrections. Students scored higher on topics learned via peer-reviewed writing assignments relative to learning in an active classroom discussion or traditional lecture. However, students with low ACT scores (17–23) did not show the same benefit from peer-reviewed written essays as the other students. These changes offer significant student learning benefits with minimal additional effort by the instructors.  相似文献

Monitoring of student learning through systematic formative assessment is important for adjusting pedagogical strategies. However, traditional formative assessments, such as quizzes and written assignments, may not be sufficiently timely for making adjustments to a learning process. Technology supported formative assessment tools assess student knowledge, allow for immediate feedback, facilitate classroom dialogues, and have the potential to modify student learning strategies. As an attempt to integrate technology supported formative assessment in the laboratory section of an upper‐level histology course, the interactive application Learning CatalyticsTM, a cloud‐based assessment system, was used. This study conducted during the 2015 Histology courses at Cornell University concluded that this application is helpful for identifying student misconceptions “on‐the‐go,” engaging otherwise marginalized students, and forming a new communication venue between students and instructors. There was no overall difference between grades from topics that used the application and grades from those that did not, and students reported that it only slightly helped improve their understanding of the topic (3.8 ± 0.99 on a five‐point Likert scale). However, they highly recommended using it (4.2 ± 0.71). The major limitation was regarding the image display and graphical resolution of this application. Even though students embrace the use of technology, 39% reported benefits of having the traditional light microscope available. This cohort of students led instructors to conclude that the newest tools are not always better, but rather can complement traditional instruction methods.

These are two major models for advanced science instruction in American high schools, the traditional honors program and the Advanced Placement (AP) program of the College Entrance Examination Board. Using the self-reports of teachers who were experienced in teaching honors and AP courses to students of similar academic preparation and ability, the author examined the perceived influences of program format upon the use of basic teaching techniques, the laboratory experience, the pace of the course, curricular freedom, and student creativity. One of the most notable aspects of the AP program is the speed at which teachers move through the curriculum. In the rush to prepare students for the exam, most AP teachers adopt a strong lecture format and minimize student-centered activities such as laboratory experimentation, student projects, and student presentations. When laboratory work is not assessed on the national AP examination, such experiences are sacrificed to provide time for lecture. When laboratory experiments are assessed, however, teachers respond by allocating more time for laboratory work, and by upgrading their exercises to make them more quantitative and experimental than those used previously or those used in honors classes. Although AP is associated with a loss in curricular freedom and flexibility, teachers perceive no clear influence of program format upon student creativity.  相似文献

A qualitative biomechanics (functional anatomy) course is a typical course in kinesiology curriculum. Most evidence suggests that biomechanics learning could be improved with the inclusion of laboratory experiences. However, implementing laboratories into biomechanics curriculum is difficult due to cost and time constraints. This study was conducted to evaluate whether hands-on activities in lecture improve qualitative biomechanics learning. A lecture format was compared to the same course with guided and unguided hands-on activities included during lecture. Test performance and student evaluations were compared between lecture formats to determine if hands-on experiences improve learning. The hands-on group performed better on the same test questions and they evaluated their overall course activities as beneficial to their learning. The findings suggest that guided hands-on experiences may improve learning compared to unguided activities. The hands-on experiences seem to provide an embodied cognitive learning experience, facilitating retention of learned material through three-dimensional and tactile mental representations. Findings from this research are currently shaping how biomechanics is taught to students at this university and could at other universities as well.  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

Laboratory and demonstration have long been used to supplement lecture in chemistry education. Current research indicates that students are better served by laboratories which exercise the higher-order cognitive skills, such as inquiry-based laboratories. However, the time and the resources available to perform these recommended types of laboratories are continually shrinking. Due to these factors, a demonstration-laboratory was designed to allow students to make observations through demonstration rather then through hands-on laboratory. For this study, the hands-on procedures of an inquiry style laboratory were replaced by an instructor demonstration of these same procedures. A significant difference was found between student conceptual understanding before and after the experiment, indicating that students performing the laboratory experiment and students viewing the demonstration-laboratory had an increase in conceptual understanding. However, no significant difference was found between the conceptual understanding of the two groups after the experiment, indicating that students learn roughly the same from both methods and that the demonstration-laboratory at least does no harm to the students conceptually. Long-term effects on student understanding were not measured. Student opinions comparing the demonstration laboratory to a hands-on laboratory were also collected and analyzed.  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

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
