    This paper attempts to bridge the psychological and anthropological views of situated learning by focusing on the concept of a learning relationship, and by exploiting this concept in our framework for the design of learning technology. We employ Wenger's (1998) concept of communities of practice to give emphasis to social identification as a central aspect of learning, which should crucially influence our thinking about the design of learning environments. We describe learning relationships in terms of form (one‐to‐one, one‐to‐many etc.), nature (explorative, formative and comparative), distance (first‐, second‐order), and context, and we describe a first attempt at an empirical approach to their identification and measurement

    The aim of teaching assembly language in a computer application course is to introduce students to abstract concepts before delving into programming details. For a novice, it is difficult to understand and learn assembly language in a short amount of time. Hence, the use of a series of computer-based programs may be helpful. Based on this perspective, a computer-based assembly language program LEARNIT was designed to establish a meaningful introduction for students to programming;The purpose of this study was twofold: (1) to evaluate the effectiveness of using computer-based instruction in learning assembly language at the undergraduate level and (2) to investigate whether learning assembly language by two instructional methods (traditional lecture/demonstration/ practice vs. computer-based instruction) was transferred to writing programs in the C language to the same degree;Forty-nine subjects participated in this study. The experimental group consisted of 25 subjects who received instruction on assembly language using the computer-based program LEARNIT. The control group consisted of 24 subjects who received instruction on assembly language using live instruction (traditional lecture/demonstration/practice);Three types of instruments were designed to measure student\u27s knowledge regarding the computer organization, assembly language, and the ability to program in C language. The results revealed that the subjects\u27 performance on a test covering assembly language was not affected by the instructional method (traditional lecture vs. computer-based instruction) in which they participated. Also, the subjects\u27 performance on a test covering the C language was not affected by the prior learning of assembly language between the experimental and control groups

    Towards a Scalable Digital Skills Training Architecture for Resource-Constrained Environments: The Case of Ayitic Goes Global in Haiti

    In developing countries such as Haiti, which are marked by high unemployment and gender inequality, online education has the potential to change lives. Returns on education are particularly high in Information Communications Technology (ICT)-intensive jobs and IT outsourcing offers opportunities for remote employment, providing alternatives for economic diversification and job creation that are particularly relevant for youth and women. However, the problem faced by many developing countries, is that traditional models, frameworks, architectures and platforms for online learning do not lend themselves well to their context and, therefore, it is important to develop context specific platforms. This need for suitable platforms has motivated the research question that this paper seeks to address, that is, “What is the appropriate architecture that supports learning strategies for delivering scalable digital skills training in a resource-constrained environment?” We propose an architecture that was developed specifically for blended learning in resource-constrained environments and describe how a prototype for this was designed, built, and deployed in Haiti. The initial findings from the application of the architecture have been extremely positive and are reflected not only in the testimonials of the participants but also by the interest of other countries of the region to adopting the proposed architecture

    This study examined the effects of a pedagogical agent (PA) with different levels of personalization in a web courseware on the learning of thematic materials. These effects were studied based on the Strategy Inventory in Language Learning (SILL). Two modes of an interactive multimedia web courseware on the theme of the holy city of AI-Quds were systematically designed and developed. While the first mode used a personalized version of the pedagogical agent (PPA), the second mode used a nonpersonalized PA (NPPA). The personalization elements include an integration of social cues, dialogue conversations, and indirect feedback. The courseware was developed based on Alessi and Trollip's (2001) Model of Design and Development of Multimedia Learning. The rationale of adopting pedagogical agents in a web learning environment is based on Vygotsky's social learning theory (1978) , communication theory (Reeves & Nass, 1996), cognitive multimedia learning theory (Mayer, 2001), and cognitive flexibility theory (Spiro et al., 1992). A 2 x 3 quasl-experimental factorial design was used in this study. The independent variables were the two modes of presentation (PPA and NPPA). The dependent variables were the learning gains and the program rating score. The moderator variable was the SILL score. 96 students studying the Arabic language at an advanced level at the International Islamic University Malaysia participated in the study. The students were divided into three groups using the PPA mode and four groups using the NPPA mode. Descriptive and inferential statistics were used to analyze the collected data. Two-way and One-way ANOVA procedures were used to examine the main and interaction effects between the independent variable and the dependent variables

    Evaluating Tactical Combat Casualty Care Training Treatments Effects On Combat Medic Trainees In Light Of Select Human Descripti

    Get PDF
    The use of military forces in urban operations has increased considerably over the past years. As illustrated by the current conflict in Iraq, the Army finds itself fighting its toughest battles in urban areas facing unconventional forces. Soldiers face many threats in hostile fire environments, whether conducting large-scale mechanized warfare, low-intensity conflicts, or operations other than war. Through 1970, there has been no demonstrable reduction in battlefield mortality rate as a percentage of all casualties since data was kept since before the Civil War. For that period of time, nearly all the reduction in overall mortality rate occurred through reduced mortality in Hospital Chain. As of 1970, about 90 percent of all combat deaths occur before a casualty reaches a definitive care facility. Tactical Combat Casualty Care (TCCC), also known as TC3, is the pre-hospital care rendered to a casualty in a combat environment. The application of TCCC principles during a tactical combat environment has proven highly effective and is a major reason why combat deaths in latest conflicts (Operation Iraqi Freedom and Operation Enduring Freedom) are lower than in any other conflict in the history of the United States. The Army continues to emphasize reducing battlefield mortality rate. Current tools and methods used for initial skills and sustainment training of combat medics throughout the Army are insufficient. New technologies are needed to provide medics with greater opportunities to develop and test their decision making and technical medical skills in multiple, COE-relevant, training scenarios. In order to address some of these requirements, the U.S. Army Research Development and Engineering Command, Simulation and Training Technology Center (RDECOM-STTC) is developing the 68W - Tactical Combat Casualty Care Simulation (TC3 Sim) for the US Army Medical Department (AMEDD) Center & School at Fort Sam Houston. The Army is considering the use of the TC3 Sim game as a tool to improve the training of individual Soldiers as well as improve the readiness of combat medics. It is the intent of this research to evaluate the effectiveness of instructional games in general and the use of the TC3 game in particular for teaching the concepts of tactical combat casualty care. Experiments were conducted to evaluate the training effectiveness of this tool in supporting the 68W10 Healthcare Specialist Course program of instruction (POI). The goal of this research is to address important questions such as: Is this game an effective tool to train Soldiers the aspects of TC3? Can knowledge gain through the use of the simulation be transferred into task related situations? How can this tool be incorporated in the current POI in order to increase training effectiveness

    This thesis deals with approaches to the evaluation of multimedia computer assisted learning in higher education. The thesis is presented in two parts. The first part consists mainly of a literature based review of the rationale and methods employed in the development of multimedia CAL systems focusing on the ability of such systems to deliver a variety of pedagogic aims and objectives which the literature on the subject generally attributes to them. This was done in order to identify and examine the important features which should be incorporated in the effective evaluation of such systems. 1) the pedagogical basis of multimedia learning environments with particular reference to the mechanism by which they claim to encourage an approach to learning which facilitates 'deep' rather than 'shallow' learning' (Chapters 3 and 4); 2) the basis on which multimedia CAL systems claim to provide interactive learning environments which allow the teaching materials to be tailored by learners to accommodate their own individual preferences for adopting particular learning strategies. In particular this focused on the importance of individual learning styles and learners' degree of computer confidence (Chapter 5); 3) the institutional/delivery factors which must be understood to explain fully the context in which evaluations are carried out and which may have important effects on the outcomes of evaluation (Chapter 6). This literature review, together with a practical survey of a range of existing CAL courseware and an e-mail survey of CAL developers provides the basis for presenting an approach to evaluation which differentiates systems on the basis of the pedagogic approach they adopt and the context in which they are implemented. Finally, a critical review of existing evaluation methods was undertaken and important elements within these methods were incorporated into a new framework for evaluation. The framework provides a tool for determining an evaluation strategy that encompasses all stages of development, formative and summative evaluation of CAL courseware. Evaluation is based on the explicit aims and objectives of the courseware being provided and is moderated by contextual factors that define the pedagogical approach being taken, any individual learner differences that must be taken into account, and the institutional/delivery context within which the courseware is used. An analysis of the implications of the framework when formulating an evaluation strategy demonstrates weaknesses in the assessment instruments currently being used in evaluation studies - particularly for providing reliable measures of 'learning effect' as part of summative evaluation and also with respect to accurate quantification of costs associated with development and use of CAL courseware. The second part of the thesis tests the framework. The approach taken was to develop and formatively and summatively assess a multimedia CAL system used to teach parts of a course on bibliographic classification to students at the Robert Gordon University in Aberdeen. Qualitative and quantitative tests to accomplish this are described and the result of statistical analyses of learner performance when using the system are presented. This empirical study provides further insights into the practical problems involved in developing and evaluating a multimedia CAL system and in particular highlights: 1) the influence which individual learning style (as measured by the Gregorc Style Delineator) has on student performance in a context in which postgraduate students were required to use the CAL courseware rather than attend lectures - results indicate that CAL does not serve all learners equally; 2) the importance of the delivery context in a study in which undergraduate students were provided with CAL materials to supplement the delivery of their course. The evaluation framework was found to be a robust framework for developing and testing didactic teaching packages which were developed in the context of improving the quality of the teaching and learning of bibliographic classification to both undergraduate and postgraduate students. Recommendations are provided for future research based on using the framework to explore other contexts in which courseware is developed and implemented
