A multidimensional unfolding technique that is not prone to degenerate solutions and is based on multidimensional scaling of a complete data matrix is proposed: distance information about the unfolding data and about the distances both among judges and among objects is included in the complete matrix. The latter information is derived from the…

The first challenge of accomplishing the goals of any successful instructional system depends on accurately assessing learners and leveraging the information to improve learning (e.g., Conati, 2002; Park & Lee, 2003; Shute, Lajoie, & Gluck, 2000; Snow, 1994). This paper describes an approach for modeling key competencies and developing…

Education within Second Life frequently recapitulates the "sage on the stage" as students sit their avatars down in chairs in the virtual world and listen to or read an instructor's lecture while watching a slideshow. This conceptual article explores alternative active learning techniques supporting independent and collaborative learning…

Science education is concerned with the meaningful pursuit of comprehension, knowledge and understanding of scientific concepts and processes. In Vygotskian social constructivist learning, personal interpretation, decision-making and community cooperation fosters long-term understanding and transference of learned concepts. The construction of…

This paper discusses the pedagogical and technological aspects of assessing wiki-based collaborative learning activities. The first part of the paper presents a general framework of collaborative learning assessment. The framework is based on four aspects of assessment, characterized by four questions: who, what, how and by whom. The second part…

This article discusses activities carried out in the virtual world of Second Life (SL) as part of a compulsory class in the first year of an undergraduate programme. The paper identifies the contribution of SL to the students' learning environment and an Inquiry Based Learning (IBL) approach to programme design. The reasons for taking an IBL…

This article described the methods of media education development of personality (including the audience's individual, "creative critical thinking" corresponding to "conceptual" (knowledge of media culture theory), "sensory" (intentional communication with mass media, orientational experience in genre and topical…

Teachers' continuing professional development, that is an essential part of their professional career, is the subject of constant demand of them and of each educational reform interest. The rapid growth of technology and the choices of teaching and learning that it provides give possibilities for synchronous and asynchronous methods of distance…

The purpose of this proposed research study is to empirically explore the nature of virtual communities of practice (CoP) in a global organisation within the context of its International Corporate Volunteer (ICV) Program. This study investigates whether and how the use of virtual CoP evolves and becomes embedded within this organization. Following…

Over the course of the last several decades, K-12 educational systems have begun to adopt digital technologies to support teaching and learning. These tools have enabled the rise of online schools as well as fundamentally changing practices of school leadership. However little attention has been given to how instructional leadership is changed…

High fidelity simulation is a well documented adjunctive teaching method in medical and nurse practitioner programs, but few studies of effectiveness on this technology on the development of competency have emphasized pre-licensure associate degree level programs. This study explored student competency in the application of the nursing process…

Value-added modeling is an alternative approach to test-based accountability systems based on the proportions of students scoring at or above pre-determined proficiency levels. Value-added modeling techniques provide opportunities to estimate an individual teacher's effect on student learning, while allowing for the possibility to control for the…

The purpose of this dissertation is to examine teaching and learning in virtual worlds such as "Second Life" (SL). This research is designed to address the following questions: What are the pedagogical practices in virtual worlds? What are the strengths and weaknesses of these practices? How do these practices change at different course levels?…

Assessment of complex task performance is crucial to evaluating personnel in critical job functions such as Navy damage control operations aboard ships. Games and simulations can be instrumental in this process, as they can present a broad range of complex scenarios without involving harm to people or property. However, "automatic"…

This policy brief, a quick look at some aspects of the debate, illustrates the differences in New York City public schools that would result when layoffs are determined by seniority in comparison to a measure of teacher effectiveness. Due to data limitations and an interest in simplicity, this analysis employs the value added of teachers using the…
