The effects of instructional media: identifying the task demand/media match†

Task instruction may be presented in many forms. However, training system designers are often forced to depend on intuition when choosing a presentation medium. Though past research has investigated the effectiveness of instructional media types, results have been mixed with no clear recommendations of which medium to use for instruction. An organizational framework for matching the appropriate medium or media to a learning situation is necessary for progress to occur in this research area. Through three experiments, we investigated the attributes of audio and video as instructional media, identified tasks for which we might predict the most beneficial instructional media, and tested our proposed organizational framework by manipulating the difficulty of the task and the complexity of the instructions. Older and younger adults participated in the experiments to help us understand differences in training needs for varying cognitive and perceptual abilities. We provide the basis for a taxonomy of instructional media and task demands, to be added through further research.  相似文献   

Cognitive load imposed by ultrasound‐facilitated teaching does not adversely affect gross anatomy learning outcomes          下载免费PDF全文

Ultrasonography is increasingly used in medical education, but its impact on learning outcomes is unclear. Adding ultrasound may facilitate learning, but may also potentially overwhelm novice learners. Based upon the framework of cognitive load theory, this study seeks to evaluate the relationship between cognitive load associated with using ultrasound and learning outcomes. The use of ultrasound was hypothesized to facilitate learning in anatomy for 161 novice first‐year medical students. Using linear regression analyses, the relationship between reported cognitive load on using ultrasound and learning outcomes as measured by anatomy laboratory examination scores four weeks after ultrasound‐guided anatomy training was evaluated in consenting students. Second anatomy examination scores of students who were taught anatomy with ultrasound were compared with historical controls (those not taught with ultrasound). Ultrasound's perceived utility for learning was measured on a five‐point scale. Cognitive load on using ultrasound was measured on a nine‐point scale. Primary outcome was the laboratory examination score (60 questions). Learners found ultrasound useful for learning. Weighted factor score on “image interpretation” was negatively, but insignificantly, associated with examination scores [F (1,135) = 0.28, beta = ?0.22; P = 0.61]. Weighted factor score on “basic knobology” was positively and insignificantly associated with scores; [F (1,138) = 0.27, beta = 0.42; P = 0.60]. Cohorts exposed to ultrasound had significantly higher scores than historical controls (82.4% ± SD 8.6% vs. 78.8% ± 8.5%, Cohen's d = 0.41, P < 0.001). Using ultrasound to teach anatomy does not negatively impact learning and may improve learning outcomes. Anat Sci Educ 10: 144–151. © 2016 American Association of Anatomists.  相似文献   

The common first year programme: some lessons from a construction science course     

Patricia McLaughlin  Nicholas Simpson 《Teaching in Higher Education》2013,18(1):13-23

In 2005, the School of Property, Construction and Project Management at RMIT University, Melbourne, introduced a new curriculum format for all first year students. All students enrolling in one of the four undergraduate degrees offered by the school commenced a common first year programme. This new curriculum was adopted to provide students with a broader depth of knowledge and experience across all study areas and to provide greater skill enhancement for graduates. The common first year university experience allows students to build a multidisciplinary degree based upon their interests and skills. But the common first year has created a number of challenges for the lecturing staff: extremely large classes, space and resourcing issues, assessment and administration problems; greater strains upon technology; and increase in the impersonal nature of the learning environment. This paper examines how one of these large first year classes (construction science) was conducted to address some of the learning issues arising from a common first year. It describes how students were encouraged over the semester to electronically build and create a classroom resource of e-reference material on construction science topics, which was the basis for classroom discussion, interaction and assessment. The result was an electronic reference folder on CD that provided students with both a starting point for assignments, class interaction and assessment, and the development of vital information technology literacy skills.  相似文献   

Navigational Structures and Information Selection Goals: A Closer Look at Online Selectivity

Using an experimental design coupled with Web-tracking technology, this study explores 2 factors that influence levels of congruent information gathering online. The first factor compares the navigational structure of 2 distinct Web pages—the more open, user-directed search engine versus the organized, assembled structure of a portal Web page. The second factor tests the role of goals for information seeking—telling subjects they will soon engage in a discussion with another person who either disagrees with their viewpoint, agrees, is undecided, or no discussion treatment. Results indicate both experimental factors independently contribute to selectivity in online information seeking.  相似文献   

Philosophy and educational policy: possibilities,tensions and tasks     

Terence H. McLaughlin 《教育政策杂志》2013,28(4):441-457

In this study, we investigate two principals’ learning in a progressive district in the southern United States. Both principals talked about ‘ownership’ and ‘continuous progress'as key to education reform, yet their words carried different meanings for learning. Principals’ use of reform terminology was embedded within two distinctly different communities of principal's practice ‐‐ Total Quality Management and ‘whole language’. We conclude by discussing ways to bridge such gaps in understanding among principals and communities by creating opportunities for learning and discourse. Educational administrators might thereby talk about and explore the different nuances of meaning they bring to their practice.

This article employed cluster analysis and multidimensional scaling techniques to develop a working typology of relevant compliance‐gaining message strategies. Subjects constructed and sorted strategies they reported to use in three compliance‐gaining situations. The resultant typology included “direct‐rational,” “manipulation,” “exchange” and “threat” strategies. A category of “expertise claims” strategies emerged in the solutions for a negotiating situation. Some of the obtained categories supported strategies used in Clark (1979) and Fitzpatrick and Winke (1979), providing independent support for the existence of some aspects of their taxonomies. It was concluded that future research on identifying factors influencing strategy preference strive to incorporate more relevant forms of strategy choices.  相似文献

A comparison of self-recording and self-recording plus consequences for on-task and assignment completion     

T.F. McLaughlin 《Contemporary educational psychology》1984,9(2):185-192

The purpose of the present experiment was to compare the effects of providing backup reinforcers for accurate self-recording on both attending and academic output. Twelve behaviorally disordered special education students were randomly placed in one of three groups: self-recording (N = 4); self-recording + backups (N = 4), and a control group (N = 4). The outcomes revealed significantly different performance for on-task behavior and assignment completion. On-task and academic responding was significantly higher for both the self-recording and self-recording + backups groups when compared to a control group. Additional comparisons indicated that the performance of the two groups who self-monitored were not statistically different for either measure. Maintenance of treatment effects was higher for two groups (self-recording and self-recording + backups) than for the control group. These differential outcomes were discussed in terms of (a) accuracy of self-recording, (b) nature of the dependent variables employed, (c) ceiling effects, and (d) possible vicarious effects. The advantages of using self-recording with and without consequences were noted.  相似文献
