Lecture capture technologies (LCT) such as Echo360, Mediasite, and Tegrity have become very popular in recent years. Many studies have shown that students favor the use of such technology, but relatively little research has studied the impact of LCT on learning. This article examines two research questions: (1) whether the use of LCT actually enhances learning outcomes, and (2) how instructors can increase students’ use of lecture capture materials. We address these questions using data from an undergraduate Operations Management course at a mid‐size, public university. Results indicate that access of lecture capture videos is associated with higher exam scores, even after controlling for previous exam performance. In addition, efforts to promote the use of lecture capture materials increase their use. We offer several suggestions to instructors who wish to increase their students’ use of lecture capture materials, which are equally applicable across all disciplines.  相似文献

Although online education is popularized, it is in a developing stage that continues to struggle with communicating and engaging with students. The question remains on how students can be better engaged in online educational materials that are presented in asynchronous media, especially in lecture videos. Thus, using engagement theory, the present study explored how online lecture videos can be improved by incorporating entertainment education. Using a public lecture video found on YouTube, an online survey (N = 133) was conducted to identify digital storytelling techniques and their effects. Results revealed that these techniques that are often utilized in entertainment became meaningful components to increase student engagement and learning outcomes. However, they can also negatively affect instructor credibility, which could suggest the need to increase instructors’ skills. The implications for the development of lecture videos using entertainment and its potential to positively impact online education are discussed.  相似文献

The understanding of measurement is related to the understanding of the nature of science—one of the main goals of current international science teaching at all levels of education. This case study explores how a first-year university physics course deals with measurement uncertainties in the light of an epistemological analysis of measurement. The data consist of the course documents, interviews with senior instructors, and laboratory instructors’ responses to an online questionnaire. During laboratory work, uncertainties are expressed in the large majority of the measurements made by the students but only in less than half of their calculation results. The instructors’ expectations are that students systematically estimate uncertainties so that they become aware that measurements and calculations are never exact. However, since uncertainties are not specified for the values given in the laboratory guides, uncertainties are often missing from the results of students’ calculations. The potential side effects of students’ measurement understanding are discussed and suggestions for improvements are proposed.  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

Promoting students’ conceptual understanding and academic language development is a primary goal of instructors in all subject areas. These goals, however, are sometimes hindered by the way students’ learning is assessed. In many college-level courses, knowledge-level tests that assess concrete thinking associated with superficial approaches to teaching are frequently used. Rubrics used to grade short open-ended responses often have vague criteria subjectively applied to a rating scale. To address these issues, this paper uses a new lens, shaped from the ideas of Vygotsky, a cultural-historical theorist, for understanding the development of academic language use (in Vygotskian terms, thinking that demonstrates conceptual understanding) and its assessment. Vygotsky’s stages of concept learning are applied to form criteria on a short-answer response rubric. Examples of students’ academic language use according to developmental level are provided. Recommendations for the adaptation of this type of classroom assessment for use in other courses are made, along with suggestions for future research.  相似文献

This paper postulates that having students engage in albeit limited and flawed research is a more effective way of changing attitudes than lecture or discussion. A common goal of the introductory linguistics course is to instill healthy language attitudes, but there is little extant research on the pedagogy of linguistics indicating how this may be accomplished. This case study presents an experimental design that allows students to develop empathy for speakers of stigmatized dialects and serves simultaneously to introduce students to the scientific method and to reinforce the idea of linguistics as a science. It offers ideas that instructors in any discipline dealing with multiculturalism may be able to adapt.  相似文献

Notetaking and review are positively related to academic achievement, but many students record too few notes to benefit fully from these activities. This paper presents ten factors that may constrain notetaking and review, and provides corresponding implications for improving these study behaviors and for conducting further research. Some instructional implications are that students should record more extensive and conceptual notes and that instructors can help students by organizing their presentations, reducing lecture rate, pausing for notetaking, emphasizing key ideas and encouraging alternate frameworks for notetaking and review. Instructors can also facilitate learning by providing learners with notes for review and with knowledge about testing. In addition, instructors should consider the cognitive processing differences among students because certain learners are likely to find notetaking dysfunctional relative to other means of acquisition. The implications for research focus on determining the optimal notetaking and review activities.  相似文献

Abstract

A second course in linear algebra that goes beyond the traditional lower-level curriculum is increasingly important for students of the mathematical sciences. Although many applications involve only real numbers, a solid understanding of complex arithmetic often sheds significant light. Many instructors are unaware of the opportunities afforded by the early introduction of complex arithmetic. Most elementary properties of complex numbers have immediate matrix analogues and many important theorems can be deduced, or at least postulated, from the basics of complex arithmetic alone.  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

eTextbooks are both texts and tools. They provide opportunities for textbook companies to expand their services. Some large textbook companies are offering extensive educational technology products and services along with texts. These etexts, integrated into the Learning Management System (LMS), give instructors opportunities to use integrated assessments, data collection tools with in-depth usage statistics, and social networking features that allow instructors and students to interact within the publisher's material. News stories often discuss problems with blended and online learning and contentious relationships between faculty and vendors; etexts are part of the discussion. This paper describes findings from narrative interviews with instructors who have used etexts, focusing on affordability, access, privacy, and outsourcing. The goal is to inform instructors and administrators of some pros and cons of etexts.  相似文献

Abstract

In higher education, supporting students with special educational needs (SEN) necessitates an understanding of these needs, additional teaching aids and innovative ideas. The teacher must be an integral part of this support process, and this is difficult for the majority of teachers, due to their lack of core understanding of SEN. However, teachers can focus on their core skills and content knowledge, and have immense alacrity to explore potential options to support their students with SEN. I decided to support my students with SEN by adapting my PowerPoint presentations according to their requirements. PowerPoint presentations usually provide concisely summarised information to students that often lead to confusion in their pre-lecture or post-lecture review. This lack of comprehensive subject information within PowerPoint presentations can have serious implications for students with SEN and their note-takers if no other teaching resources or aids are available to help them. Students with SEN and note-takers reported this concern to me at Aberystwyth University, UK. Consequently, I began to explore ways to make my PowerPoint presentations extra helpful for my students with SEN. After a review of best practices for students with SEN based on universal design for learning and a few trials, I developed a dual PowerPoint presentation (DPP), lecture handouts and comprehensive lecture notes. Subsequently, I successfully employed this approach in the delivery of some of the undergraduate modules of a BSc computer science programme. Feedback from students with SEN, note-takers and the student support department, and examination results showed the success and potential of this DPP approach.  相似文献

Lectures are often thought of in terms of information transfer: students (do not) “get” or “construct meaning of” what physics professors (lecturers) say and the notes they put on the chalkboard (overhead). But this information transfer view does not explain, for example, why students have a clear sense of understanding while they sit in a lecture and their subsequent experiences of failure to understand their own lecture notes or textbooks while preparing for an exam. Based on a decade of studies on the embodied nature of science lectures, the purpose of this article is to articulate and exemplify a different way of understanding physics lectures. We exhibit how there is more to lectures than the talk plus notes. This informational “more” may explain (part of) the gap between students’ participative understanding that exists in the situation where they sit in the lecture on the one hand and the one where they study for an exam from their lecture notes on the other. Our results suggest that in lectures, concepts are heterogeneous performances in which meaning is synonymous with the synergistic and irreducible transactions of many different communicative modes, including gestures, body movements, body positions, prosody, and so forth.  相似文献

Sixty‐six students completed two questionnaires to describe their approaches to study and the relationship to their personal preference for either the conventional lecture (CL) or self‐learning package (SLP) as methods of instruction. The students were randomly assigned to either an SLP and a CL group and received instruction on the same topic. Then, six weeks after the lecture all students were given a 30‐minute test to examine their level of understanding. Ten students, chosen at random, were interviewed further to assess their attitude towards learning. The inference drawn from the results is that more students preferred CL to SLP, however there was no correlation between students’ study approach and their preference for different teaching methods, nor did the study demonstrate that either method of instruction was superior when measured by test performance, suggesting a need to review independent study packages to better match student needs. Interview analysis showed that the students were highly dependent on reassurance from their lecturers, emphasising the negotiated nature of learning.  相似文献

In a Food Processing–Unit Operations course, students learn the basic equipment that comprises unit operations and techniques commonly used in the food industry to prepare, process, and preserve a variety of food products. Due to the complexity of these operations, students frequently struggle with applying food processing principles to predict how unit operations influence the physical, biochemical, sensory, and nutritional properties of foods. This study is designed to evaluate how pre‐class readings and in‐class group activities improve the students’ learning in a Food Processing course. The survey after the exams shows that 48 and 60% of students agree that reading assignments and in‐class group activities help them understand the course material better, respectively. The mean value of exam scores shows that the students in the intervention section (Spring 2018) had significantly higher scores (88.4%) than that of the two previous sections without intervention (77.6%, Spring 2016 and 82.8%, Spring 2017) (P < .05). It is concluded that using a flipped class element like providing reading assignments and quizzes before the lecture can be an effective preparation technique for students as well as providing the instructors with critical insight into the students’ level of understanding before the lecture. This allows the instructor to focus time spent in class on areas in which students struggle the most.  相似文献

The large lecture section is often perceived as a homogeneous mass of students who can be taught satisfactorily by a single teaching method — usually lectures, textbooks, and objective exams. An attempt to improve the quality of teaching and learning was made by offering three distinct options to 695 students enrolled in two large classes: (1) conventional lecture/objective exam format; (2) small groups of five to eight students; (3) independent study. The students responded with 86% selecting the conventional method, 11% choosing small groups, and 3% deciding upon independent study. Students in the conventional classes tended to have high scores on Rotter's External Control Scale and high scores on personality need scales (Personality Research Form) for harm avoidance, order, social recognition, and succorence; they also tended to be less intellectually inclined and more vocationally oriented. The students in nonconventional options tended to have high personality need scores for cognitive structure, achievement, autonomy, and understanding.Portions of this paper were presented at Annual Meetings of the American Sociological Association, Denver, September, 1971 and the Illinois Sociological Association, Chicago, October, 1972. We are indebted to Fred Strodbeck, Robert Sutherland, Gene Jabker, Richard Clayton, Kay Clifton, and Wendy Rhodes for critical comments to an earlier draft of this paper.  相似文献

In spite of advances in physics pedagogy, the lecture is by far the most widely used format of instruction. We investigated students’ understanding and perceptions of the content delivered during a physics lecture. A group of experts (physics instructors) also participated in the study as a reference for the comparison. During the study, all participants responded to a written conceptual survey on sound propagation. Next, they looked for answers to the survey questions in a videotaped lecture by a nationally known teacher. As they viewed the lecture, they indicated instances, if any, in which the survey questions were answered during the lecture. They also wrote down (and if needed, later explained) the answer, which they perceived was given by the instructor in the video lecture. Students who participated in the study were enrolled in a conceptual physics course and had already covered the topic in class before the study. We discuss and compare students’ and experts’ responses to the survey questions before and after the lecture.  相似文献

For several years the National Technical Institute for the Deaf (NTID) at the Rochester Institute of Technology has offered a course that focuses on preparing video resumes. Professionals from the Instructional Television Department and the National Center of Employment for the Deaf have collaborated with communication instructors to develop this option for NTID students. This paper describes the instruction and evaluation process from the perspective of NTID instructors, students, and other technical professionals. Employers who have hired NTID students and those who have no familiarity with deaf employees also participated in the evaluation. Their comments give valuable insights into the often different perspectives of deafness between those who have worked with deaf employees and those who lack such experience. Video resumes were found to be a viable tool in the job search, and the process of preparing the video was found to be a stimulating and rewarding experience for the participating students.  相似文献

In many life science classrooms, instructors rely upon lecture presentations to efficiently present course content. Students, in this case, act as passive learners with little opportunity to test their knowledge for gaps or misconceptions. The goal of the project described here was to determine whether a collaborative quiz protocol that guided students to discuss their understanding with their peers would improve learning and academic performance. The project took place during a single semester and was composed of two studies: a preliminary study that incorporated short-answer quizzes into the curriculum and a comprehensive study that incorporated short-answer quizzes and justify/explain quizzes in which students were expected to select an answer and then justify or explain it. Students took all quizzes twice, first independently and then collaboratively with classmate(s). Learning was assessed using multiple-choice exam questions based upon quiz topics. Students scored significantly higher on exam questions associated with justify/explain quiz topics than on those associated with short-answer quiz topics.  相似文献
