This paper proposes a methodology to calculate both the difficulty of the basic problems and the difficulty of solving a problem. The method to calculate the difficulty of problem is according to the process of constructing a problem, including Concept Selection, Unknown Designation, and Proposition Construction. Some necessary measures observed…

Simple matching models of decision making are no longer sufficient as a basis for career counselling and education. The challenge for contemporary careers advisers is how to communicate some of the complexities of modern career development to their students; in particular, the apparently contradictory relationship between the need for planning and…

Diagrams are considered to be invaluable teaching and learning tools in biochemistry, because they help learners build mental models of phenomena, which allows for comprehension and integration of scientific concepts. Sometimes, however, students experience difficulties with the interpretation of diagrams, which may have a negative effect on their…

The purpose of this research was to examine the validity of the 55-item Revised Token Test (RTT) and to compare traditional and Rasch-based scores in their ability to detect group differences and change over time. The 55-item RTT was administered to 108 left- and right-hemisphere stroke survivors, and the data were submitted to Rasch analysis.…

The objective of this study was to examine the nature of preservice teachers' evaluations of elementary mathematics problems using the Mathematical Tasks Framework (MTF), a model designed to discriminate among tasks according to their cognitive complexity. We also tested the relationship between mathematics content knowledge and problem length on…

This study used principles underlying item generation theory to posit competing perspectives about which features of situational judgment tests might enhance or impede consistent measurement across repeat test administrations. This led to 3 alternate-form development approaches (random assignment, incident isomorphism, and item isomorphism). The…

This paper examines the difference in learning outcomes between two groups of students, one of which used the "French Tutor," a multimedia package, and the other a textbook to learn the formation and use of two French past tense verbs: the perfect and the imperfect. Unlike the textbook, the "French Tutor" included visual…

Computer adaptive testing is the study of scoring tests and questions based on assumptions concerning the mathematical relationship between examinees' ability and the examinees' responses. Adaptive student tests, which are based on item response theory (IRT), have many advantages over conventional tests. We use the least square method, a…

This study looks at a specific application of Ainsworth's conceptual framework for learning with multiple representations in the context of using multiple sequential graphic organizers that are student-generated for a process-writing task. Process writing refers to writing that consists of multiple drafts. It may be a process of re-writing without…

This study examined how 30 general education and 30 special education elementary grade teachers rated the importance of social skills to classroom success and positive relationships of children with learning disabilities, and also considered how teachers determine ratings of difficulty of acquisition of social skills by children with learning…

This Monte Carlo study examined the effect of complex sampling of items on the measurement of differential item functioning (DIF) using the Mantel-Haenszel procedure. Data were generated using a three-parameter logistic item response theory model according to the balanced incomplete block (BIB) design used in the National Assessment of Educational…

This paper deals with the problems that arise in performance assessment from the granularity that results from having a small number of tasks or prompts and raters of responses to these tasks or prompts. Two problems are discussed in detail: (1) achieving a satisfactory degree of reliability; and (2) equating or adjusting for differences of…

Of the four language skills, reading is probably tested most often, and it may seem to be the easiest to test. However, testing reading proficiency has its difficulties, and the test constructor must be aware of several issues. Reading involves a number of skills, and the number and complexity of these must be recognized. Choosing the text to test…

Computerized adaptive (CA) testing uses an algorithm to match examinee ability to item difficulty, while self-adapted (SA) testing allows the examinee to choose the difficulty of his or her items. Research comparing SA and CA testing has shown that examinees experience lower anxiety and improved performance with SA testing. All previous research…

An examination of the content and level of mastery required of students taking statewide mathematics achievement tests was conducted to provide clues about the kind and level of mathematics valued in the United States. Proposals for voluntary national tests also contributed to the rationale for the study. In particular, this study: (1) examined…
