Although researchers in undergraduate science, technology, engineering, and mathematics education are currently using several methods to analyze learning gains from pre- and posttest data, the most commonly used approaches have significant shortcomings. Chief among these is the inability to distinguish whether differences in learning gains are due to the effect of an instructional intervention ...

Introduction This paper describes a year-long study of computer-mediated communication (CMC) tool use by high school students. The purpose of this study is to explore a range of variables related to characteristics of students in order to form a better understanding of how to construct learning environments where CMC tool use is an integral part of daily activity. Student characteristics are ex...

Trends of School Effects on Student Achievement: Evidence from NLS:72, HSB:82, and NELS:92 The impact of schools on student achievement has been of great interest for the last four decades. This study examines trends of school effects on student achievement employing three national probability samples of high school seniors: NLS:72, HSB:82, and NELS:92. Hierarchical linear models are used to in...

To the new international students who learn Japanese out-class in Japan, it is too hard to find different suitable ways for different students that have different learning characteristics. This paper considers to solve this problem, which is how to help new international students who learn Japanese for out-class learning according student’s own learning frequency. This paper uses learning frequ...

This paper reports on an innovative, computer-mediated, educational technology application in a simulated distance learning environment. As an initial evaluation, real student groups completed an entire university course using this state-of-the-art, two-way synchronous audio/visual communication technology, Distributed Tutored Video Instruction (DTVI). The study reported here explored student p...

This paper presents the reflective perspectives of the student and supervisor in a successful computer-mediated research relationship. Key contributing factors are discussed in a dialogue format covering the role of computermediated communication (CMC), the projection of social presence, student self-efficacy beliefs, the role of information and communication technology (ICT), and interaction i...
