Q181 .A1 R47 and NCSU e-journal V15, 1997. This study involved a convenient sample of two – tenth grade chemistry classes for approximately three weeks. The treatments were randomly assigned to the two groups, one group using computer-supported graphing activities, and the other using noncomputer supported activities. There was no statistically significant differences on line graphing mean scores as measured by the Individualized Test of Graphing in Science and Performance Assessment Test. In my opinion, the treatment time was too short to see any difference, and the sample size of 45 total students was too small to see differences when looking at treatment and reasoning levels. A few good references on previous studies on line graphs are included in the article. Digital Video Harwood, W. S., and McMahon, M. M., (1997). Effects of integrated video media on student achievement and attitudes in high school chemistry. Journal of Research in Science Teaching, 34(6), 617-631. Q181.A1 J68 & NCSU e-journal V33, 1996 The study explored the effects of an integrated video media curriculum enhancement on students’ achievement and attitudes in a first year general high school chemistry course within a multiculturally diverse metropolitan school district. Through the use of a treatment-control experiment design, approximately 450 students in grades 9-12 were sampled on measures of chemistry achievement and attitude over athe period of one academic year. The results revealed significantly higher acienvement scores on standardized measures of achievement as well as on microunit researcher-designed, criterion-referenced quizzes for the treatment student who experience a general chemistry course enhance with an itegrated use of a structured chemistry video series. Correlation of student achievement with logical thinking ability revealed that students with highe levels of logical thinking ability benefited most from the video-enhanced curriculum. Treatment students also scored significantly higher than contro students on the chemistry attitude instruments. The teachers integrated the use of the World of Chemistry video series in the treatment lessons. They used the teacher lesson guides associated with each 30-minutes videotape, which was designed to enable the teacher to stop the videotape approximately 5-7 minutes for a question-answer interaction time. There were at least eight video-enhanced 1 treatments over the course of the academic year. This looks like a good study to use as a reference for the use of video in science. The study was well done and well written, using a large sample size over a long duration of time. Kearney, M., Treagust, D.F., Yeo, S., and Zadnik, M.G. (2001). Student and teacher perceptions of the use of multimedia supported Predict-Observe-Explain tasks to probe understanding. Research in Science Education, 31, 589-615. NCSU e-journal only, beginning V31, 2001 The researchers used 16 POE computer tasks incorporating digital video clips of real-life events to elicit their preconceptions and encourage discussion of student ideas. Two classes were used in the study, one consisting of 18 females and the other consisting of 26 males. The main research question in this qualitative study was “How do the students and teachers perceive the use of the POE tasks within a computer environment?” The topic of discussion for the research was projectile motion. Data collection for the research included participant observation, collected documents, audio and video recordings, semi-structured interviews and questionnaires. The students enjoyed being in control of the whole program, feeling that they had more inut into the video demonstration. Some students found the video medium more convincing than static graphics and text. They appreciated the opportunity of observe an exact replica of the demonstration as many times as they wanted. The also appreciated the everyday context provided in most of the video clips. Students and teachers perceived the slow-motion, rewind and step-frame facilities inherent in the video medium as most useful in making clinical observation of event. Both teachers acknowledged the ability of the digital video clips to present time consuming demonstrations that would be difficlt to set up in a classroom. Credibility of the video-clips was important to the students. Russell, J. W., Kozma, R. B., Jones, T., Wykoff, J, Marx, N. and Davis, J. (1997). Use of simultaneous-synchronized macroscopic, microscopic, and symbolic representations to enhance the teaching and learning of chemical comcepts. Journal of Chemical Education, 74(3), 330-334. QD1 .J93, and NCSU e-journal 73(9) 1996 The study was an initial examination of the effectiveness of the gaseous equilibrium module of 4M:CHEM software that was developed to synchronize the macroscopic (video), microscopic (animation) and symbolic (equations) representations of the equilibrium reaction. The lecturers demonstrated the software in from of the class during two lectures. Pretests and posttests consisted of five constructed-response items used in previous research, for which students were asked to give brief answers, calculate answers, and draw diagrams. The pretest was given during the first 10 minutes of the first lecture and the posttest was given during the last 10 minutes of the second lecture. Of the 500 students in the two classes used in the study, 295 students attended both sessions. These were the students used in the analysis. The posttest scores were significantly greater that the pretest scores (p<0.0001). The initial assessment of 4M:CHEM in two lecture sections for two one-hour presentations showed an increase in 2 students’ understanding of characteristics of systems at equilibrium and the effects of temperature on these systems. The article was not written well as a research study article. The emphasis seemed to be on the software, and not on the educational research using the software. However, Kozma’s idea of synchronizing three types of images is similar to our idea of graphvideo-animation. Interactive Video Analysis Beichner, R. J. (1996). The impact of video motion analysis on kinematics graph interpretation skills. American Journal of Physics, 64(10), 1272-1277. QC1 .A5 and NCSU e-journal 8(1) 1940-present Three hundred sixty eight high school and college students took part in a study where the effect of graduated variations in the use of a video analysis tool was examined. Postinstruction assessment of student ability to interpret kinematics graphs indicates that groups using the tool generally performed better than students taught by traditional instruction. The data further established that the greater the integration of video analysis into the kinematics curriculum, the larger the educational impact. An additional comparison showed that graph interpretation skills were significantly better when a few traditional labs were replaced with video analysis experiments. Limiting student experience with the video analysis technique to a single teacher-led demonstration resulted in no improvement in performance relative to traditional instruction. The greatest impact came from a combination of demonstrations with hands-on labs. Good reference for a proposal. Appropriate design and analysis. This is definitely a seminal article for video analysis of motion. Boyd, A. and Rubin, A. (1996). Interactive video: A bridge between motion and math. International Journal of Computers for Mathematical Learning, 1, 57-93. QA20.C65 I58, and NCSU e-journal 1(1) 1996-present. This paper examined the characteristics of interactive digitized video as a medium in which motion is presented to students learning graphical representations. In comparing video to both everyday perceptions and mathematical representations, they construct a conceptual framework that compares these three contexts along several dimensions: object extent, scale, time, and space. The researchers interviewed eight students while they interacted with the video system. One student’s experience in constructing graphs of her own design from a video image is examined. The analysis of this student is examined through the conceptual framework what was presented that included 1) Scale and object event; 2) Conceptions of time in video-based contexts; and 3) The salience of intervals and speed. Other discussion includes: 1) When a graph is the result of a student’s manipulation of video frames, the appearance of the object in the video may affect its representation on the graph; 2) If a graph of a video scenario is going to be labeled in terms of “real distance”, a scale must be determined using some video object whose real 3 size is known; 3) Graphs derived from video may predispose students to representing distance on the horizontal axis; and 4) Video and similar media make intervals – and therefore speed – salient to students. The articles does not present much that can be used in the proposal, but it presents some interesting ideas regarding a conceptual framework regarding the frame-by-frame analysis of motion.

Journal of Research in Science Teaching. 34(5), 467-489. Q181.A1 J68 & NCSU e-journal V33, 1996-present The investigation examines the effect of interactive digital video on student learning and attitudes in an introductory college physics course. The participants were 87 volunteers out of a class of 100 prospective elementary teachers taking the physics course. The volunteers were required to complete at least 3 of the 5 activities outside of normal class and lab times, which lasted about 2 hours for each activity. The study measured students’ computer attitudes and found improvement in students’ feelings of comfort in using computers after completion of the activities. They found students’ prior computer experience did not influence their perceptions of the activities. The majority of participants perceived discussion and the computer visualization techniques as being very effective in helping them learn Students’ understanding of the physics concepts were assess and the participants’ scores were compared with nonparticipants’ scores. Although analysis of variance statistical procedures revealed no significant differences between the two groups (n=87 for treatment, n=13 for control), the results of this study indicate that sophisticated instructional video software can be perceived as easy to use and effective by students who are novices and experts in using computers. In reviewing the analysis of the understanding of physics concepts, the results could be confounded in that different students chose to participate in the five interactive digital video activities. For example, 56 out of 100 did the first activity, 53 for the second, 52 for the third, 39 for the fourth, and 37 for the fifth. Eighty-seven students participated in at least 3 activities. Although the content items on the test were analyzed by each activity, I believe the overall effect is compromised in this design. It would be hard to determine the academic promise of the technology when some students may have only worked with it for 6 hours (3 sessions x 2 hours). The article is well written and has great references. Rodrigues, S., Pearce, J., and Livett, M. (2001). Using video analysis or data loggers during practical work in first year physics. Educational Studies, 27(1), 31-43. L11 .E525 and NCSU through EBSCO since 1990. The paper reports on a project investigating student’ learning processes when video analysis and data logging practical work were used in a first year undergraduate physics course. Student volunteers were interviewed. Students were motivated by the tasks and felt the tasks helped them to understand physics concepts. Students used elements of the 4 video analysis and data logging practical work to reinforce already existing ideas rather than challenge the robustness of their existing ideas. Three groups (47 students) took an alternative video analysis laboratory (VL) exercise, and 11 groups (160 students) took the traditional data logging laboratory (DL) exercise. All students participated on an introductory three-hour data logging session on the concept of motion. This was followed one week later by either the VL or DL laboratory exercise. Both groups were given identical questions to answer. Group interviews were held after the lab exercise. Again, I was disappointed with the treatment time of the activity. The interviews were administered after only one three-hour lab. Although quantitative data was collected, it was not shared in the article.

Unlike MBL, however, interactive video can analyze complex two-dimensional motion such as the motion of a cannonball fired froma projectle launcher (Eacalada, Grabhourn, & Zollman, 1996). Unlike MBL, interactive video allows students to observe real-time graphs of the data being collected at the same time the video of the event is shown (Chaudhury & Zollman, 1994). Use of interactive video can eliminate the need for special experimental apparatus connecting wires to computer interfaces, and setting up photogates or sonic rangers typically found in MBL situations, so that students can focus on analyzing the data rather then on the apparatus (Reference)”.

Clark argued that it is not media that caused the proposed changes in learning; he contended that media are merely vehicles to deliver instruction. Clark believed that media and associated attributes only influence the way learning is delivered. In contradiction to Clark, Kosma (ref) offered the argument that we must continue to investigate instructional technology because it is the dynamic union of the learner working with the medium that is important. Depending on the learner and the medium, the construction of knowledge will vary. Kozma’s belief are further supported and extrapolated by research work conducted on situated cognition. Brown, Collins, and Duquid (1989) proposed that knowledge is situated. That is, it is bound to any activity, context, or culture in which it is 15 developed. If this is true, then the learner and the learning are heavily influenced and affected by the instruction use of media.” In Harwood and McMahon 1997.
