Interactive Visual Least Absolutes Method: Comparison with the Least Squares and the Median Methods
Peer reviewed Peer reviewed
Direct linkDirect link
Kim, Myung-Hoon; Kim, Michelle S. – Journal of Chemical Education, 2016
A visual regression analysis using the least absolutes method (LAB) was developed, utilizing an interactive approach of visually minimizing the sum of the absolute deviations (SAB) using a bar graph in Excel; the results agree very well with those obtained from nonvisual LAB using a numerical Solver in Excel. These LAB results were compared with…

Curriculum, Classroom Practices, and Tool Design in the Learning of Functions through Technology-Aided Experimental Approaches
Peer reviewed Peer reviewed
Direct linkDirect link
Lagrange, J. B. – International Journal of Computers for Mathematical Learning, 2005
The paper starts from classroom situations about the study of a functional relationship with help of technological tools as a "transposition" of experimental approaches from research mathematical practices. It considers the limitation of this transposition in existing curricula and practices based on the use of non-symbolic software like dynamic…

Personal Computer Usage in Community College Accounting Courses.
Peer reviewed Peer reviewed
Cerullo, Michael; And Others – Computers and Education, 1989
Reports on the results of a 1985 survey of two-year community colleges that was conducted to determine the use of personal computers in accounting courses. Types of hardware and software used are discussed, planned purchases are indicated, courses using microcomputers are described, and future use is explored. (four references) (LRW)

Prior Computer-Related Experiences and Hypermedia Metacognition.
Peer reviewed Peer reviewed
Reed, W. Michael; Giessler, Steven F. – Computers in Human Behavior, 1995
Discusses the relationship between prior computer experiences and the linear or nonlinear steps students choose when working with hypermedia environments and time spent on task (based on a study of graduate students). Experience with content-area software, word processing, databases, spreadsheets, programming, hypermedia, and authoring are…

The Dimensionality and Correlates of Flow in Human-Computer Interactions.
Peer reviewed Peer reviewed
Webster, Jane; And Others – Computers in Human Behavior, 1993
Defines playfulness in human-computer interactions in terms of flow theory and explores the dimensionality of the flow concept. Two studies are reported that investigated the factor structure and correlates of flow in human-computer interactions: one examined MBA students using Lotus 1-2-3 spreadsheet software, and one examined employees using…

Peer reviewed Peer reviewed
PDF on ERIC Download full text
Moore, John W.; Mitchem, Cheryl E. – Journal of College Teaching & Learning, 2004
This paper provides a model of course-embedded assessment for use in an undergraduate Accounting Information Systems course, and reports the results obtained from implementation. The profession's educational objectives are mapped to specific computer skills and assignments, to provide direct evidence of learning outcomes. Indirect evidence of…
