Artificial Tutoring Systems: What Computers Can and Can't Know
Theodore W. Frick
Journal of Educational Computing Research Vol. 16, No. 2 (1997) pp. 107–24
Maccia's epistemology of intelligent natural systems implies that computer systems must develop qualitative intelligence before knowledge representation and natural language understanding can be achieved. Emotion and sensation--capabilities which...

Analysis of Patterns in Time: A Method of Recording and Quantifying Temporal Relations in Education
Theodore W. Frick
American Educational Research Journal Vol. 27, No. 1 (1990) pp. 180–204
Analysis of patterns in time (APT) is presented as a method for gathering information about observable phenomena so that probabilities of temporal patterns of events can be estimated empirically. APT is illustrated through a classroom study of 25...

EXSPRT: An Expert Systems Approach to Computer-Based Adaptive Testing
Theodore W. Frick
Expert systems can be used to aid decision making. A computerized adaptive test (CAT) is one kind of expert system, although it is not commonly recognized as such. A new approach, termed EXSPRT, was devised that combines expert systems reasoning and ...

Bayesian Adaptation during Computer-Based Tests and Computer-Guided Practice Exercises
Theodore W. Frick
Journal of Educational Computing Research Vol. 5, No. 1 (1989) pp. 89–114
Demonstrates how Bayesian reasoning can be used to adjust the length of computer-guided practice exercises and computer-based tests to help make mastery or nonmastery decisions. Individualization of instruction is discussed, and the results of an...

A Comparison of an Expert Systems Approach to Computerized Adaptive Testing and an Item Response Theory Model
Theodore W. Frick
Expert systems can be used to aid decisionmaking. A computerized adaptive test is one kind of expert system, although not commonly recognized as such. A new approach, termed EXSPRT, was devised that combines expert systems reasoning and sequential...

An Investigation of the Validity of the Sequential Probability Ratio Test for Mastery Decisions in Criterion-Referenced Testing
Theodore W. Frick
The sequential probability ratio test (SPRT), developed by Abraham Wald, is one statistical model available for making mastery decisions during computer-based criterion referenced tests. The predictive validity of the SPRT was empirically...

Computerized Adaptive Mastery Tests as Expert Systems
Theodore W. Frick
Journal of Educational Computing Research Vol. 8, No. 2 (1992) pp. 187–213
Discussion of expert systems and computerized adaptive tests describes two versions of EXSPRT, a new approach that combines uncertain inference in expert systems with sequential probability ratio test (SPRT) stopping rules. Results of two studies...

Instructor and Student Classroom Interactions during Technology Skills Instruction for Facilitating Preservice Teachers' Computer Self-Efficacy
Joyce H. L. Koh; Theodore W. Frick
Journal of Educational Computing Research Vol. 40, No. 2 (2009) pp. 211–228
Technology skills instruction is an important component of educational technology courses, which has been shown to raise pre-service teachers' computer self-efficacy. Computer self-efficacy, in turn, is positively related to their self-efficacy for...

Changes in Student Motivation during Online Learning
Kyong-Jee Kim; Theodore W. Frick
Journal of Educational Computing Research Vol. 44, No. 1 (2011) pp. 1–23
Self-directed e-learning (SDEL) refers to electronic learning environments where there are often no peer learners or instructors regularly available. Past studies suggest that lack of time and lack of motivation are primary causes of learner...

Computerized Adaptive Testing in Instructional Settings
R Edwin Welch; Theodore W. Frick
Educational Technology Research and Development Vol. 41, No. 3 (1993) pp. 47–62
Discusses the use of computerized adaptive testing (CAT) in the classroom. Highlights include item response theory; sequential probability ratio test (SPRT); combining SPRT with expert system reasoning, resulting in EXSPRT; and a study of college...

Anonymity to Promote Peer Feedback: Pre-Service Teachers' Comments in Asynchronous Computer-Mediated Communication
Craig D. Howard; Andrew F. Barrett; Theodore W. Frick
Journal of Educational Computing Research Vol. 43, No. 1 (2010) pp. 89–112
In this quasi-experimental case study, we compared five sections of a basic undergraduate technology course. Within an asynchronous web forum, pre-service teachers wrote short critiques of websites designed by their classmates. This peer feedback...

Building a Large, Successful Web Site on a Shoestring: A Decade of Progress
Theodore W. Frick; Bude Su; Yun-Jo An
Annual Meeting of the Association for Educational Communications and Technology 2004 (October 2005)
How did we build a site that has grown to more than 6,000 Web pages and 50 million hits per year--with a few part-time people, with no budget for the first five years, and a minimal budget the next five? We will describe an efficient and effective...

User-Centered Design and Usability Testing of a Web Site: An Illustrative Case Study
Michael D. Corry; Theodore W. Frick; Lisa Hansen
Educational Technology Research and Development Vol. 45, No. 4 (1997) pp. 65–76
Presents an overview of user-centered design and usability testing. Describes a Web site evaluation project at a university, the iterative process of rapid prototyping and usability testing, and how the findings helped to improve the design....
