Judging the Constructive Impacts of Communication Technologies: A Business Education Study

Through an IBM partnership, Acadia University has the benefit of an infrastructure that places a laptop computer in the hands of some 4000 faculty and students on campus. Coupled with anytime–anyplace campus access to the computer network, the setting offers unique opportunities to study the pedagogical impacts of the use of computers in classroom instruction.University business administration courses have routinely employed case study approaches in the delivery of some course content. The research described follows the use of an elaborate case study communications networking system being used in a business course on competitive intelligence. Though the technology collage allows for certain opportunities to promote quality instruction, not all aspects of technology use were found to be productive. This paper provides an analysis of the appropriateness of technology usage in the context of a single business education course.     

Research Agendas and Computer Technology Visions: The Need for Closely Watched Classrooms

There are numerous research methodologies that may be applied to the study of computer technology, and each has the potential to provide insights into its usefulness. The selection of research methodologies should be driven by the nature of the questions under investigation rather than a predetermined idea that some research methods are superior to others. This article focuses on a particular methodology, case studies, and it describes their potential for making a unique contribution to our understanding of computer technology. The special value of case studies lies in helping us understand the complexities found in classrooms, where the multiple variables that influence computer use interact in complex ways. © 1999 IFIP, published by Kluwer Academic Publishers     

An investigation of the linkage between technology-based activities and STEM major selection in 4-year postsecondary institutions in the United States: multilevel structural equation modelling

Among the disciplines of science, technology, engineering, and math (STEM), much attention has been paid to the influences of math- and science-related learning contexts on students’ STEM major selection. However, the technology and engineering learning contexts that are linked to STEM major selection have been overlooked. In response, a nationally representative sample of young adults in the US was used to investigate the relationship between technology-based activities and students’ STEM major choices in 4-year postsecondary institutions. Multilevel structural equation modelling (ML-SEM) revealed that the frequent use of video or computer games was related strongly to students’ STEM major selections in 4-year postsecondary institutions, after taking into account demographic characteristics and math achievement scores. The results provide evidence that promoting technology-rich learning environments is a significant factor in motivating students to pursue STEM careers.

Computer technology and complex problem solving: Issues in the study of complex cognitive activity

Goals and plans organize much of complex problem solving behavior and are often inferable from action sequences. This paper addresses the strengths and limitations of inferring goals and plans from information that can be derived from computer traces of software used to solve mathematics problems. We examined mathematics problem solving activity about distance, rate, time relationships in a computer software environment designed to support understanding of functional relationships among these variables (e.g., distance =rate × time; time=distance/rate) using graphical representations of the results of simulations. Ten adolescent-aged students used the software to solve two distance, rate, time problems, and provided think-aloud protocols. To determine the inferability of understanding from the action traces, coders analyzed students' understanding from the computer traces alone (Trace-only raters) and compared these to analyses based on the traces plus the verbal protocols (Traceplus raters). Inferability of understanding from the action traces was related to level of student understanding how they used the graphing tool. When students had a good understanding of distance, rate, time relationships, it could be accurately inferred from the computer traces if they used the simulation tool in conjunction with the graphing tool. When students had a weak understanding, the verbal protocols were necessary to make accurate inferences about what was and was not understood. The computer trace also failed to capture dynamic exploration of the visual environment so students who relied on the graphing tool were inaccurately characterized by the Trace-only coders. Discussion concerns types of scaffolds that would be helpful learning environment for complex problems, the kind of information that is needed to adequately track student understanding in this content domain, and instructional models for integrating learning environments like these into classrooms.Members of the Cognition and Technology Group at Vanderbilt who have contributed to this project are (in alphabetical order) Helen Bateman, John Bransford, Thaddeus Crews, Allison Moore, Mitchell Nathan, and Stephen Owens.

Factors that influence pre-service teachers’ ICT usage in education

The purpose of the current study was to investigate the role of internal factors (e.g. attitudes towards computers and internet, self-confidence, and knowledge) and external factors (perceived support) on the level of information and communication technology (ICT) usage. The participants were 1898 pre-service teachers in Turkey. The results revealed that Turkey, like many other developing countries in the world, is in the early phase of ICT integration in education. Most pre-service teachers reported that they use only basic ICT applications for educational purposes. Internal and external factors were found to be related to each other and to ICT usage level. In general, male pre-service teachers’ knowledge and usage levels of ICT were higher than that of female teachers.
