While the need to present food science information effectively is viewed as a critical competency for food scientists by the Institute of Food Technologists, most food scientists may not receive adequate training in this area. Effective presentations combine both scientific content and delivery mechanisms that demonstrate presenter enthusiasm for the topic and generate audience interest. This paper provides food science presentation “best practices” based upon the results of the author's 10 y of experience teaching communication skills to 1st‐year graduate students. Topics include development of a “Presentation Inventory” that encourages presenters to consider why they are presenting, who they are presenting to, what information they plan to present, and how they plan to present the information. More specific sections of the paper address presentation introductions and conclusions, developing visual aids, responding to audience questions, flow, pacing, and time management, technological competency, and tips on how to practice a presentation. Such information should be applicable to all types of food science practitioners including undergraduate and graduate students, postdoctoral scholars, teaching and research academics, and government, industrial, and consulting food scientists. An awareness of such “best practices” among presenters of food science information can help raise the bar to improve the quality of contemporary food science presentations. 相似文献

SUMMARY The current study chronicles what one professor learned from teaching a distance education course with and without the aid of PowerPoint multimedia presentation software. It compares student ratings of three lectures from the same classes by the same professor; the first, a traditional lecture without any audiovisual aids; the second, a lecture supplemented by PowerPoint notes outlining the lecture; and finally, a multimedia lecture utilizing PowerPoint notes with pictures, music and animations. Students reacted no differently to any of the presentations when delivered by an experienced teacher. The students did, however, prefer PowerPoint multimedia to PowerPoint outline presentations. Suggestions for the optimal uses of presentation software are provided. 相似文献

It goes without saying that the expression “garbage in, garbage out” still applies. Poorly designed instruction cannot be
saved by a flashy, high-tech presentation. Flashy garbage is still garbage. But a high-tech presentation can be a very useful
tool for instructors and trainers to employ if the instructional material is well designed, and learning objectives require
it. If a quality presentation has been developed, it is apparent that students find the use of the graphics tablet to enhance
presentations a useful instructional technique.
I found myself, as the instructor, to be more in touch with the presentation when I used electronic mark-up of presentation
materials. The lectures felt more integrated. I could interact with the presentation more easily and effectively. I’m reminded
of what I teach in my public speaking class about visual aids — use them as an aid to, but not a replacement for, well-prepared
material — but use them. They can help clarify content, maintain interest and increase retention. Enhanced presentations can
do that even more effectively. 相似文献

Many of the projects and assignments we have our students complete for our classes include a multimedia presentation. Why are we not teaching our students how to cite their sources for these presentations? Writing style (APA, MLA, or Chicago) does not matter. Regardless of whether it is a paper or multimedia presentation students should always cite their sources, otherwise plagiarism is occurring. This is a skill we must teach and demand that our students take responsibility for when completing multimedia presentations. This article covers a brief overview of copyright law, provides helpful resources for students and teachers, and outlines a model that can be used in citing sources in multimedia presentations. This model goes beyond the producer required credit slide to argue for the inclusion of “in product/text” citations for multimedia presentations. 相似文献

Presentation feedback can be limited in its feed-forward value, as students do not have their actual presentation available for review whilst reflecting upon the feedback. This study reports on students’ perceptions of the learning and feed-forward value of an oral presentation assessment. Students self-marked their performance immediately after their presentation, after reviewing a video recording of their presentation and wrote a reflection relating to their experience. Survey data revealed that most students viewed all aspects of the assessment task positively and they rated the process as providing substantial learning value. They also indicated that the video review and overall assessment exercise provided valuable feed-forward information that would assist them to improve future presentations. These data were further supported by content analysis of the qualitative data. Students noted that they perceived the video review task as self-enabling. They also noted that the self-reflection and self-marking exercise provided time for thought although it was personally challenging. Therefore, via carefully designed assessment, it is possible to provide a deep learning opportunity from oral presentations that can feed-forward to enhance students’ future presentations. 相似文献

Two models of attribution were compared in assessing counselors' reactions to clients' initial attributional presentations. Predictions derived from the content model of attribution suggested that certain attributional content in client presentations (e.g., internal and unstable explanations) would create more favorable counselor impressions. The belief similarity model predicted that counselor–client agreement on explanations for the client's problem was more critical. Results partially supported both models: Counselors reacted most positively when they disagreed with the client's internal attribution and the most negatively when they disagreed with the client's external attribution. 相似文献

This study investigated (1) the extent to which presentations of measurement error in score reports influence teachers’ decisions and (2) teachers’ preferences in relation to these presentations. Three presentation formats of measurement error (blur, colour value and error bar) were compared to a presentation format that omitted measurement error. The results from a factorial survey analysis showed that the position of a score in relation to a cut-off score impacted most significantly on decisions. Moreover, the teachers (N = 337) indicated the need for additional information significantly more often when the score reports included an error bar compared to when they omitted measurement error. The error bar was also the most preferred presentation format. The results were supported in think-aloud protocols and focus groups, although several interpretation problems and misconceptions of measurement error were identified. 相似文献

This paper represents a condensation of a 2-hour oral presentation that made extensive use of visual aids in color, many of which could not be reproduced. Several of the areas that received more elaboration in the oral presentation have been shortened in the interest of space. 相似文献

AbstractIn 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

Previous studies have shown that anatomy students who complete oral laboratory presentations believe they understand the material better and retain it longer than they otherwise would if they only took examinations on the material; however, we have found no studies that empirically test such outcomes. The purpose of this study was to assess the effectiveness of oral presentations through comparisons with other methods of assessment, most notably, examination performance. Specifically, we tested whether students (n = 256) performed better on examination questions on topics covered by their oral presentations than on other topics. Each student completed two graded, 12‐minute laboratory presentations on two different assigned topics during the course and took three examinations, each of which covered a third of the course material. Examination questions were characterized by type (memorization, pathway, analytical, spatial). A two‐way repeated measures analysis of variance revealed that students performed better on topics covered by their presentations than on topics not covered by their presentations (P < 0.005), regardless of presentation grade (P > 0.05) and question type (P > 0.05). These results demonstrate empirically that oral presentations are an effective learning tool. Anat Sci Educ 2: 260–264, 2009. © 2009 American Association of Anatomists. 相似文献

Reaction times and picture evaluations by 18 adults with hearing loss were compared with those of 18 matched controls during two visual priming tasks. In Task 1, participants reacted to sexual and plant target pictures (while influenced by similar preceding pictures) by pressing "sex" or "plant" buttons. In Task 2, they evaluated target Japanese ideographs (while influenced by preceding positive or negative facial expressions as prime pictures) by pressing "positive" or "negative" buttons. In Task 1, the controls had the faster responses. In Task 2, they showed the usual congruent priming effect during very short prime presentations. Participants with hearing loss showed this effect only during short and long prime presentation times; thus, they were not superior to the controls in picture recognition, instead showing (a) impaired processing of visual information or (b) impaired perceptual-motor skills regarding quick responses to visual information (or both). 相似文献

Visual representations play a critical role in the communication of science concepts for scientists and students alike. However, recent research suggests that novice students experience difficulty extracting relevant information from representations. This study examined students’ interpretations of visual representations of DNA replication. Each of the four steps of DNA replication included in the instructional presentation was represented as a text slide, a simple 2D graphic, and a rich 3D graphic. Participants were middle grade girls (n = 21) attending a summer math and science program. Students’ eye movements were measured as they viewed the representations. Participants were interviewed following instruction to assess their perceived salient features. Eye tracking fixation counts indicated that the same features (look zones) in the corresponding 2D and 3D graphics had different salience. The interviews revealed that students used different characteristics such as color, shape, and complexity to make sense of the graphics. The results of this study have implications for the design of instructional representations. Since many students have difficulty distinguishing between relevant and irrelevant information, cueing and directing student attention through the instructional representation could allow cognitive resources to be directed to the most relevant material. 相似文献
