The instructional design and the corresponding research on student learning of two virtual laboratories that provide an engineering task situated in an industrial context are described. In this problem-based learning environment, data are generated dynamically based on each student team's distinct choices of reactor parameters and measurements.…

A well-designed experiment is the best method for establishing efficacy of any intervention, be it medical, behavioral, or educational in nature. This paper reviews the steps necessary in conducting a comparative experiment in an educational setting, and illustrates how these steps might be fulfilled within the context of a large-scale randomized…

In this article we describe the MentorBlog project, which facilitated the mentoring of trainee teachers in the postcompulsory education sector through the use of blogs. In an experimental design, the study compared their experiences with students who received traditional mentoring. Blogs were used by the trainees to communicate with their mentors…

Increased flexibility and modularisation in higher education complicates the process of learners finding their way through the offerings of higher education institutions. In lifelong learning, where learning opportunities are diverse and reach beyond institutional boundaries, it becomes even more complex to decide on a learning path. However,…

The authors used the 5E learning cycle (engage, explore, explain, extend, and evaluate) and a pulmonary carbon dioxide mystery to introduce eighth grade students to the study of chemistry. The activity engages students in measurement, data collection, data analysis, media and internet research, research design, and report writing as they search…

In this paper, we present an interactive teaching approach to introduce the concept of optimal design of experiments to students. Our approach is based on the use of spreadsheets. One advantage of this approach is that no complex mathematical theory is needed nor that any design construction algorithm has to be discussed at the introductory stage.…

Experimental methods have been used extensively for many years to conduct research in education and psychology. However, applications of experiments to investigate technology and other instructional innovations in higher education settings have been relatively limited. The present paper examines ways in which experiments can be used productively…

The usual formula for variance depending on rounding off the sample mean lacks precision, especially when computer programs are used for the calculation. The well-known simplification of the total sums of squares does not always give benefit. Since the variance of two observations is easily calculated without the use of a sample mean, and the…

The NASA's Mars Student Imaging Project (MSIP) is led by the Arizona State University (ASU) Mars Education Program, a major partner of NASA's Mars Exploration Program. MSIP is based on the National Science Education Standards and includes curriculum on terrestrial planet characteristics, experimental design, and proposal writing. Three spacecraft…

Merging to e-mail is a process which can be used to help the instructor communicate with students. Two possible ways this process can be used in education are: to update students on their grades and to conduct research. This paper first discusses reasons for using e-mail in education and then goes on to describe how to create a merge to e-mail…

Describes two QuickBASIC programs that provide students direct experience with interpreting correlation scatter-plots. Maintains that the programs can be used in classroom exercises to highlight factors that influence the size of a Pearson correlation coefficient. (CFR)

Describes a QuickBASIC program for demonstrating the differences between main effects and interactions in factorial designs. The program can be used in conjunction with a traditional lecture to improve student understanding and develop skills in recognizing main effects and interactions from graphic displays. (CFR)

Describes a graduate research methods course in which students were taught electronic communications skills. Lists three course requirements involving electronic mail, subscriptions to electronic journals, and participation in electronic academic lists. Discusses six problems that emerged and the student evaluations. (CFR)

Design research has grown in importance since it was first conceptualized in the early 90s, but it has not been adopted for research in instructional technology in higher education to any great extent. Many researchers continue to conduct studies that principally seek to determine the effectiveness of the delivery medium, rather than the…

This paper investigated the methodological challenges related to the use of computer-mediated communication (CMC) to investigate the impact of gender identity on student perceptions of university life. This longitudinal research project at the University of Cambridge (England) sought to determine the reasons for the disparity in numbers of…
