An Excel program developed to assist researchers in the determination and presentation of confidence intervals around commonly used score reliability coefficients is described. The software includes programs to determine confidence intervals for Cronbachs alpha, Pearson r-based coefficients such as those used in test-retest and alternate forms…

This article shows how Microsoft Excel's ability to vary parameters with sliders allows students to "stand on the shoulders of giants" and discover characteristics of polynomial functions.

Athabasca University--Canada's Open University evaluated learning management systems (LMS) for use by the university. Evaluative criteria were developed in order to ensure that different platforms were tested against weighted criteria representing the needs of the university. Three LMSs (WebCt, LotusNotes, and Moodle) were selected for the…

Little research has been done examining the role of errors in learning computer software. It is argued, though, that understanding the errors that people make while learning new software is important to improving instruction. The purpose of the current study was to (a) develop a meaningful and practical system for classifying computer software…

In this paper an attempt is made to highlight some issues of interpretation of statistical concepts and interpretation of results as taught in undergraduate Business statistics courses. The use of modern technology in the class room is shown to have increased the efficiency and the ease of learning and teaching in statistics. The importance of…

We describe a computer tutorial that introduces the concept of the steady state in enzyme kinetics. The tutorial allows students to produce graphs of the concentrations of free enzyme, enzyme-substrate complex, and product versus time in order to learn about the approach to steady state. By using a range of substrate concentrations and rate…

Teaching pre-service and in-service teachers to use technologies in their classrooms begins with their training at the university. Many teacher education programs require students to take a foundational level course in technology education. As these foundational courses are continually revamped to include technologies for various disciplines,…

This paper was prepared in response to the Conference Board of Mathematical Sciences recommendations for the preparation of secondary teachers. It shows how using trigonometry as a conceptual tool in spreadsheet-based applications enables one to develop mathematical understanding in the context of constructing geometric representations of unit…

Regardless of where you are in your school improvement process, here's a book that helps you make sure you have all the right elements working for you in the right way. The authors take you through the core processes that are essential for all school improvement efforts--from establishing your mission to differentiating your supervision based on…

Pre-registration nursing and midwifery students are under considerable pressure to acquire the necessary information technology (IT) skills by the time they embark on a professional nursing career. There is a multitude of research findings detailing the use of computer-based learning materials, IT training initiatives and how such materials are…

It is common to find students believing that they have a high skill level in computer use yet this does not normally include proficiency in the use of computer packages for data presentation. This exercise develops team work in data collection, requires the production of a simple spreadsheet, and the exporting of the data from that into one or…

Many students have difficulty finding remainders instead of quotients in the division of two numbers. Students are too quick to use technology and cannot interpret the output correctly. Moreover, many students are not accustomed to doing different yet applicable mathematics. As with all branches of mathematics, modular arithmetic and congruences…

This paper describes a personal computer spreadsheet set up to carry out hierarchical log-linear analyses, a type of analysis useful for institutional research into multidimensional frequency tables formed from categorical variables such as faculty rank, student class level, gender, or retention status. The spreadsheet provides a concrete vehicle…

Presents selected responses to the question "The Farmer's Dilemma" that represent the thinking of sixth-, seventh-, and eighth-grade students. Indicates that by being given the freedom to use a variety of methods, most students found at least one solution or demonstrated an understanding of the restrictions set by the problem. (ASK)

Describes a Web site that contains Microsoft Excel workbooks that draft consistent short-run and long-run cost curves and the text describing them. Details a common error in representing the curves. Reports that the Web site also presents revenues and profits for a price taker and a price maker. (JEH)
