Many researchers have investigated the effects of students' prior knowledge upon learning chemistry, for example, the tenacity of alternative conceptions. Knowledge about learning also shapes students' learning of chemistry. This research describes the development of CHEMX, a survey instrument that measures an aspect of knowledge about learning…

Recent research studies have reported on how novices and experts differ in storing, organizing, and retrieving subject matter knowledge and on how they apply their knowledge to solve new problems. These findings have been integrated and implemented in a computer environment to help novices improve their problem-solving skills. An outline of this…

Despite improvements in educational indicators, such as enrolment, significant challenges remain with regard to the delivery of quality education in developing countries, particularly in rural and remote regions. In the attempt to find viable solutions to these challenges, much hope has been placed in new information and communication technologies…

This paper examines the educational impacts of the Berkshire Wireless Learning Initiative (BWLI), a pilot program that provided 1:1 technology access to all students and teachers across five public and private middle schools in western Massachusetts. Using a pre/post comparative study design, the current study explores a wide range of program…

Computer aided assessment (CAA) tools are more and more widely adopted in academic environments mixed to other assessment means. In this article, we present a CAA Web application, named eWorkbook, which can be used for evaluating learner's knowledge by creating (the tutor) and taking (the learner) on-line tests based on multiple choice, multiple…

This study evaluated expert system diagnoses of examinees' solutions to complex constructed-response algebra word problems. Problems were presented to three samples (30 college students each), each of which had taken the Graduate Record Examinations General Test. One sample took the problems in paper-and-pencil form and the other two on computer.…

This study attempts to estimate Structure of Learning Outcome (SOLO) levels in mathematics using the Partial Credit and Rating Scale models. A 30-item test comprising 10 testlets of 3 items each was designed and administered to 674 lower secondary school students. The items were arranged in a hierarchical manner, each testing SOLO levels in this…

The perspective of the examinee during the administration of a computerized adaptive test (CAT) is discussed, focusing on issues of test development. Item review is the first issue discussed. Virtually no CATs provide the opportunity for the examinee to go back and review, and possibly change, answers. There are arguments on either side of the…

Instruments used in a study by M. B. Kinzie and M. A. Delacourt (1991), the Attitude towards Computer Technologies (ACT) and the Self-efficacy for Computer Technologies (SCT), assess preservice teachers' perceived usefulness of and comfort level with specific computer technologies. This study uses a population confirmed to be similar to that used…

A study determined the viability and effectiveness of the Computerized Competent Speaker Evaluation System. A total of 659 comments made by undergraduate students about the paper version of the Competent Speaker Speech Evaluation Form were subjected to two Q sorts. The 635 comments that emerged were incorporated into the evaluation system during…

The Educational Testing Service is moving rapidly to computerize its tests for admissions to postsecondary education and occupational licensure/certification. Computerized tests offer important advantages, including immediate score reporting, the convenience of testing when the examinee wishes, and for adaptive tests, equal accuracy throughout the…

The relationships among teaching, testing, and learning are examined and reconceptualized based on different theories and computer adaptive testing. Approaches that integrate teaching, testing, and learning include: (1) behavioral psychology; (2) cognitive psychology; and (3) computer adaptive testing (CAT). Some behaviorists have assumed that all…

The instructional validity of computer administered tests was studied with a focus on whether differences in test scores and item behavior are a function of instructional mode (computer versus non-computer). In the first of 3 studies, performance test scores for approximately 400 high school students in 1990-91 for tasks accomplished with the…

This study examined the effects of high school course choices, grades, and Grade Ten Assessment Test scores (GTAT) in math and reading, along with race and gender, on student performance on a computerized placement test (CPT) administered upon entry to community colleges in Florida. The sample consisted of 19,736 African-American, white, and…

The reliability of four branching algorithms commonly used in computer adaptive testing (CAT) was examined. These algorithms were: (1) maximum likelihood (MLE); (2) Bayesian; (3) modal Bayesian; and (4) crossover. Sixty-eight undergraduate college students were randomly assigned to one of the four conditions using the HyperCard-based CAT program,…
