This study aims to find the answers to how an online interactive video editing tool for teachers to use would be designed. To find out the answers to this, students studying to become teachers and experienced teachers were interviewed and used for observations and usability testing of a prototype. In total there were 27 unique data gathering situations with 11 unique participants. The five teacher students who were participating were all teacher students at Linnaeus University in Växjö. The six experienced teachers have been teaching for many years and are currently lecturing teachers about new technology that can be used in the classroom. The result from interviews, observations and literature search contributed to a list of requirements which in turn became a prototype. What has been discovered is that teachers need a tool which is easy to use with interactions and functions such as adding clickable annotations to clips and creating playlists which will help teachers plan ahead and save time during lectures.

E-commerce has been said to bring value to businesses by improving business efficiency and effectiveness and thus providing business with a competitive advantage through the potential benefits that it offers (Cloete, Courtney & Fintz, 2002). However, despite the potential benefits that e-commerce can offer, the adoption of B2C e-commerce in South African construction SMMEs is low and this is due to the challenges associated with e-commerce (Vaithanathan, 2010; Uzoka, Shemi & Seleka, 2007; Love & Irani, 2004; Anumba & Ruikar, 2002). These e-commerce challenges include: high implementation costs, lack or poor infrastructure, inadequate resources, low use of e-commerce by suppliers and consumers, lack of access to e-commerce, computer illiteracy, deficiency in understanding the potential benefits of e-commerce and security concerns (Vaithanathan, 2010; Uzoka, Shemi, & Seleka, 2007; Mensah, Bahta, & Mhlanga, 2005; Cloete, Courtney, & Fintz, 2002). Therefore, due to these e-commerce challenges, construction SMMEs do not exploit the business advantages that e-commerce offers. In order to assist South African construction SMMEs in their efforts to improve their business effectiveness and efficiency through commercial technologies.

The purpose of this investigation was to develop and test the effectiveness of an interactive video program for training in qualitative movement analysis. Students (n=24) from an intact elementary physical education methods class were trained to identify four qualitative standards associated with the mature performance of the overhand throw. Subjects were matched on the basis of pretest scores and assigned to receive either interactive video instruction, videotaped instruction, or no instruction. The results from an ANCOVA were significant indicating a difference between groups. Duncan's multiple range test results showed that the interactive video and videotaped instructional methods were superior to no training but there were no significant differences between groups receiving instruction. The findings from this investigation support the conclusion that the application of interactive video instruction to qualitative movement analysis is an effective strategy although it is not superior to video taped instruction. However, its application may be beneficial in mass instruction. / Master of Science

The purpose of this study was to investigate the efficiency, effectiveness, and impact of learner control when using interactive video as a training tool. Food service managers (H=60) were randomly assigned to two groups, experimental and control. Each group was trained on the subject matter of food service sanitation following the program developed by the National Restaurant Association's Educational Foundation entitled, Applied Foodservice Sanitation: A Coursebook. Students of the control group were trained by the traditional, lecture-pupil technique (LPl. students of the experimental group were trained via interactive video (IV). The students of the experimental group were further randomly assigned to subgroups; limited interactive (L-I) and fully-interactive (F-I). Immediately following training, all students were given a review of the subject matter and then took the certification exam. Using t-tests to analyze scores between groups and multiple regressions to analyze the effect of time on score fc,r the experimental groups, effectiveness, efficiency, and predictability of score based on time-to-train were measured. The findings indicated that the IV program was as effective as the traditional technique and was significantly more efficient. The multiple regression analysis revealed that time was not a predictor of score; however, when students increased their interactivity while using IV programs, learning (effectiveness) increased. Interactive video programs that are designed to be limited-interactive are as effective and can be as efficient as fully-interactive programs. students who trained in small groups tended to score equally with students trained individually. / Ed.

In order to produce an Interactive MultiMedia Application (IMMA), the developer of that application needs a set of tools for such tasks as capturing, modifying, editing, sequencing, synchronizing, archiving, versioning, and backing up. The heart of this set of tools is an Integrator which can be used by the developer to assemble various multimedia objects into an IMMA and provide the end-user with ways of interacting with that IMMA. This work focuses on that essential tool - the multimedia Integrator. The Integrator uses a graphical interface that exploits a notation like that of a musical score. The IMMA produced by the Integrator is inherently parallel and includes elements required to define the asynchronous nature of applications, along with a standard set of multimedia objects. The timing and synchronization representation used by the Integrator is based on the model presented by the HyTime standard group. We also have explored the representation of our objects and their attributes according to the Multimedia Hypermedia Expert Group (MHEG) standard model as defined by the MHEG committee. This work formalizes the design of the Integrator and its constructs using the HyTime Draft International Standard (ISO/IEC DIS 10744). Multimedia application objects and their attributes are described, timing and synchronization aspects of the Integrator and some examples of IMMAs are explained, and several of these examples using the HyTime document structuring language are given. / Master of Science

By and large, contemporary design models do little more than acknowledge the art and science of media development, and instead, place inordinate emphasis on media selection. While many texts on instructional design will discuss, in general terms, the circumstances under which media needs to be developed, their primary focus is on the selection and customization (e.g., repurposing videodiscs} of extant materials that support previously adopted goals, objectives, and instructional strategies. Although contemporary instructional design models do acknowledge computer-assisted instruction in general terms as part of the media selection and development processes, they fail to address specifically the development issues confronted when digital video is selected as an integral component of computer-based applications. Practitioners wishing to develop their own instructional materials (particularly those which incorporate digital video) are provided few specific details for creating those products in the context of a systems approach to instructional development. This study examined the essential design tasks involved in incorporating digital video into computer-based applications. The strategy adopted for this study consisted of the following: 1) The author produced a computer-based application for The Museum of Natural History at Virginia Tech that integrated both digital motion-video sequences and still-image graphics; 2) Each of the development “steps” made by the author was preserved through a set of design notes as well as videotaped records of designer and participant comments; 3) The design notes and videotaped records were subjected to qualitative analyses borrowed from standard ethnographic research procedures; 4) Subsequent considerations for integrating digital video into computer-based applications were abstracted from the analyses and presented as practical guidelines for practitioner-developers pursuing media development. A “traditional” model of instructional design was also modified to reflect state-of-the-art media development strategies. The model illustrates the general procedure of media development and places it in the context of a larger, systems approach to instructional design. The development steps include defining the product, conducting research, brainstorming ideas, generating design solutions, developing the prototype, testing the prototype, and developing the end-product. The model also illustrated (by way of example) the creation of the computer-based application developed for The Virginia Museum of Natural History at Virginia Tech. / Ph. D.
