An Experimental Study of Teachers' Verbal and Nonverbal Immediacy, Student Motivation, and Cognitive Learning in Video Instruction

Description: This study used an experimental design and a direct test of recall to provide data about teacher immediacy and student cognitive learning. Four hypotheses and a research question addressed two research problems: first, how verbal and nonverbal immediacy function together and/or separately to enhance learning; and second, how immediacy affects cognitive learning in relation to student motivation. These questions were examined in the context of video instruction to provide insight into distance learning processes and to ensure maximum control over experimental manipulations. Participants (N = 347) were drawn from university students in an undergraduate communication course. Students were randomly assigned to groups, completed a measure of state motivation, and viewed a 15-minute video lecture containing part of the usual course content delivered by a guest instructor. Participants were unaware that the video instructor was actually performing one of four scripted manipulations reflecting higher and lower combinations of specific verbal and nonverbal cues, representing the four cells of the 2x2 research design. Immediately after the lecture, students completed a recall measure, consisting of portions of the video text with blanks in the place of key words. Participants were to fill in the blanks with exact words they recalled from the videotape. Findings strengthened previous research associating teacher nonverbal immediacy with enhanced cognitive learning outcomes. However, higher verbal immediacy, in the presence of higher and lower nonverbal immediacy, was not shown to produce greater learning among participants in this experiment. No interaction effects were found between higher and lower levels of verbal and nonverbal immediacy. Recall scores were comparatively low in the presence of higher verbal and lower nonverbal immediacy, suggesting that nonverbal expectancy violations may have hindered cognitive learning. Student motivation was not found to be a significant source of error in measuring immediacy's effects, and no interaction effects were detected ...

Test of Proportional Wire Chambers in Hybrid Systems

Description: This is an agreement between the National Accelerator Laboratory and Professor I. Pless of MIT representing the experimenters to provide selected instrumentation for the beam to the 30-inch bubble chamber, and to use the hybrid chamber for an experiment. This document contains an enumeration of the major items needed for the proper execution of Experiment No. 154 as expressed in the proposal for the experiment, subsequent correspondence, and the draft agreement. This agreement covers phases I and II of the experiment. In Phase I the experimenters will design, construct and bring into operation a complete upstream proportional chamber system. This system will tag incident beam particles as to type by correlating the Cerenkov signals furnished by NAL with the proper incoming particle. In addition, the system will measure the position of the incident particle which passed through the momentum slit. The system will contain three proportional wire chambers (3 planes each) which will provide data suitable for defining the incident beam both as to position and angle. The experimenters will furnish the computer, magnetic tape units, programs, and all necessary readout and interface hardware. When the system is installed, debugged, documented and completely functional, it will be turned over to NAL to be operated as a general facility. Phase II of the experiment consists of an exposure of about 20,000 30-inch bubble chamber pictures ({approx}6 beam tracks per picture) correlated with data from a set of proportional wire chambers downstream from the chamber. The experimenters expect to demonstrate the utility of the proportional chamber spectrometer by attempting to analyze every event. They will do this before requesting a major exposure.

The Effects of Videotaping and Playback on the Communication Performance of the Introverted and Extroverted Individual

Description: The problem with which this investigation is concerned is that of determining the effects of videotaping and subsequent playback on the communication performance of introverted and extroverted individuals. The principal method of determining these effects is the subjective judgment of a panel of qualified speech instructors who viewed videotaped speeches made by the subjects. All subjects were repeatedly subjected to videotaping, and half were exposed to playback. Statistically, by using one-way analysis of covariance, the effects of playback were measured: The speaking scores achieved by the experimental introverts and extroverts were compared with the speaking scores of the control introverts and extroverts. Sixty-four subjects were used; these were limited to college students enrolled in the teacher-education program. To carry out the purposes of the study, the following hypotheses were tested: 1. There will be a significant difference between the scores of introverted trainees who are videotaped and exposed to playback and the scores of introverted trainees who are videotaped but not exposed to playback. 2. There will be a significant difference in the scores of extroverted trainees who are videotaped and exposed to playback and the scores of extroverted trainees who are videotaped but not exposed to playback.

Space age. Final report

Description: Space age had its world premiere at the large-screen Spaceport Theater at Cape Canaveral/Kennedy Spaceport. The first program was screened for invited guests who, that morning, also witnessed a launch of the Space Shuttle. Since that mission carried the first Japanese astronaut, it was a nice tie-in to the substantial co-production participation of space age by NHK Japan. A special press conference for the series and a twenty-minute preview reel was screened for journalists who were also at the Cape for the shuttle launch. Numerous first-hand newspaper articles were generated. CNN ran part of the preview reel. The first episode in the series, `The Quest for Planet Mars,` then ran twice a day for a week, prior to the Public Broadcasting Service broadcast on an Imax format screen at the Spaceport theater. The program was seen by thousands of visitors. Space age also had a special premier at the National Academy of Sciences in Washington, DC with some 400 special guests, including scientists and government agency representatives.

Develop Solid State Laser Sources for High Resolution Video Projection Systems

Description: Magic Lantern and Honeywell FM and T worked together to develop lower-cost, visible light solid-state laser sources to use in laser projector products. Work included a new family of video displays that use lasers as light sources. The displays would project electronic images up to 15 meters across and provide better resolution and clarity than movie film, up to five times the resolution of the best available computer monitors, up to 20 times the resolution of television, and up to six times the resolution of HDTV displays. The products that could be developed as a result of this CRADA could benefit the economy in many ways, such as: (1) Direct economic impact in the local manufacture and marketing of the units. (2) Direct economic impact in exports and foreign distribution. (3) Influencing the development of other elements of display technology that take advantage of the signals that these elements allow. (4) Increased productivity for engineers, FAA controllers, medical practitioners, and military operatives.

Edge Polynomial Fractal Compression Algorithm for High Quality Video Transmission. Final report

Description: In this final report, Physical Optics Corporation (POC) provides a review of its Edge Polynomial Autonomous Compression (EPAC) technology. This project was undertaken to meet the need for low bandwidth transmission of full-motion video images. In addition, this report offers a synopsis of the logical data representation study that was performed to compress still images and video. The mapping singularities and polynomial representation of 3-D surfaces were found to be ideal for very high image compression. Our efforts were then directed to extending the EPAC algorithm for the motion of singularities by tracking the 3-D coordinates of characteristic points and the development of system components. Finally, we describe the integration of the software with the hardware components. This process consists of acquiring and processing each separate camera view, combining the information from different cameras to calculate the location of an object in three dimensions, and tracking the information history and the behavior of the objects.

A Comparative Analysis of the Effects of Video-Based versus Live Presentation Staff Development on Teachers' Cognitive Learning and Attitudes

Description: The problem of this study was the identification of effective and efficient means of providing quality staff development for reading instruction within a school-district setting. The study investigated the comparative effectiveness of two staff development delivery systems measured by 1) a cognitive test of a school district's reading program and 2) an affective measure of teacher attitudes toward staff development. The sample was drawn from the teacher population of a large urban school district. The 46 subjects were elementary school teachers in grades K-5 randomly divided into two groups: Group A (videotape with a trained on-site facilitator) and Group B (face-to-face live presenter). Participants in the study received training using "The Fort Worth Reading Program," a staff development program designed by the researcher. In addition to the presentation of content information, which is the central component, the program features small group discussions, off-line activities, and question and answer periods. Both groups received the same treatment with the following exception. A central component to the Group A training was the presentation of content information in a videotape format. Group B did not view the videotape, but received the same information via live presenter. Two instruments developed by the researcher were used in the study: 1) The Teacher Staff Development Questionnaire, a Likert-type survey to obtain teacher attitudes toward staff development, and 2) The Cognitive Test of Reading Knowledge, an instrument designed to measure cognitive objectives of the district's reading program. A multivariate analysis of covariance revealed no statistically significant differences between the groups. It was concluded that elementary classroom teachers, regardless of their attitudes toward staff development, learn content material equally well with either of the two delivery systems explored in this study. Specific suggestions and recommendations for further studies are addressed and discussed. Examples of the measurement instruments are included.

A Study of the Effects of a Systematic Program of Instruction in Helicopter Technology on Student Preferences for Kinds of Learning Experiences

Description: The problem of this study was to compare two methods of instruction in helicopter pilot ground training in terms of cost of training and support services and customer satisfaction upon completion of training. The purpose of the study was the evaluation of a specialized program of instruction taught on videotape by comparison with conventional instruction. The significance of the study was related to savings in costs of instruction per trainee. Research questions for the study sought significant differences between mean scores achieved by students receiving the two treatments. Data providing information on specific characteristics of the learners were gathered as a preliminary step to establish similarity of the students in the two groups compared. A table of random numbers was used to select subjects from the population of student pilots entering training for the Bell model 206B helicopter during the months of March, April and May 1981. Upon completion of the course, all students were asked to complete an evaluation opinionaire relating to satisfaction with selected aspects of the instructional program.

High-speed videography for optical and x-ray imaging

Description: The SP-2000 Motion Analysis System, or high speed video (HSV) can record up to 2000 full frames per second or up to 12,000 partial (hex) frames per second with a playback speed of 60 frames per second, thus allowing a slow down factor of up to 200 times in the recorded action. The system is quite portable as well as being capable of supporting two cameras simultaneously. The two images, which could be views of the same event from different angles and/or different fields of view or depth of field, can be viewed on the same TV monitor by use of picture inset techniques with variable size and positioning of the inset. Other useful features of the high speed video system includes a data frame and X and Y reticles that can be activated on replayed images to give accurate position data for any desired frame. The data frame gives the time of day, date, elapsed time since the beginning of recording of the particular frame being viewed, identification number, X, Y, recording rate in frames per second, frame count, tape count as well as status messages such as Stopped and Still Image. The great appeal of the high speed video system is the live camera setup conditions which allow likely success on the initial recording and the immediate playback feature common to all video systems. Also, the fact that this data is in digital format means that with our optional computer interface, information such as the aforementioned X and Y data can be directly input to a computer. These convenient features are the result of a number of technological advances. These include a solid state video sensor, specialized microgap recording heads, high density magnetic recording tape, microprocessors for a wide range of sophisticated controls.

The Development and Evaluation of a Series of Video-Tape Lessons to Supplement a College Course in Advanced Music Theory

Description: The purpose of the study was to develop and evaluate a series of video-tape lessons to supplement the traditional lecture-discussion method of teaching a college course in advanced music theory. The specific problems investigated were: 1) to evaluate the effect of video-tape material on achievement in an advanced music theory course. 2) To assess the effect of the video-tape materials on the achievement in harmony, keyboard, sight singing, and ear training for students who had differential learning ability levels. 3) To assess the attitudes toward music theory and the use of the supplemental lessons. 4) To assess attitudes toward music theory and the use of the supplemental lessons and achievement for all students involved in the study. Analysis of co-variance, simple analysis of variance, t tests, and Pearson correlations produced statistical results that led to the following conclusions: 1) Students who used the video-tape supplemental lessons did not score higher on achievement tests in harmony, keyboard, sight singing, and ear training than the students who did not use those lessons. 2) Students who used the video-tape lessons had greater variance among the ability levels on the achievement tests; and for those using the lessons, students in the low beginning-ability level did not achieve at a corresponding rate with the students in the high and middle levels. 3) Attitudes toward music theory and the use of supplemental materials were less positive for the students who used the video-tape lessons. 4) Among all participants of the evaluation, a significant relationship was found between attitudes toward music theory and the use of supplemental materials and achievement in music theory.
