The evaluation of intervention effects is an important objective of educational research. One way to evaluate the effectiveness of an intervention is to conduct an experiment that assigns individuals to control and treatment groups. In the context of pretest/posttest designed studies, this is referred to as a control-group pretest/posttest design.…

We examined the feasibility and results of a multilevel multidimensional nominal response model (ML-MNRM) for measuring both substantive constructs and extreme response style (ERS) across countries. The ML-MNRM considers within-country clustering while allowing overall item slopes to vary across items and examination of whether certain items were…

Within the theoretical framework of knowledge space theory, a probabilistic skill multimap model for assessing learning processes is proposed. The learning process of a student is modeled as a function of the student's knowledge and of an educational intervention on the attainment of specific skills required to solve problems in a knowledge…

Descriptions of growth in educational achievement often rely on the notion that higher-level students can do whatever lower-level students can do, plus at least one more thing. This article presents a method of supporting such descriptions using the data of a subject-area achievement test. Multiple content domains with an expected order of…

Consider test data, a specified set of dichotomous skills measured by the test, and an IRT cognitive diagnosis model (ICDM). Statistical estimation of the data set using the ICDM can provide examinee estimates of mastery for these skills, referred to generally as attributes. With such detailed information about each examinee, future instruction…

Measures of teacher behavior are related to student achievement in fifth grade reading and mathematics instruction. It was found that those measures of teacher behavior which were generalizable (that is, more highly reliable) were found to be significantly related to student achievement. (JKS)

A comparison of three treatments (training students to take tests, training teachers to administer tests, and reinforcing reading test score improvement) showed that group achievement scores more accurately indicate what students know if motivated to do their best in tests and take tests from teachers trained to administer standardized tests.…

Significantly more positive attitude toward subject matter of instruction was associated with the use of the criterion-referenced measure than with the norm-referenced measure; differences in attitude toward mode of instruction were not significant. (Author)

"Classroom Assessment" provides a look at assessment from the bottom up in a way that acknowledges its role in the day-to-day activities of a classroom teacher. It provides insights to students in teacher education programs and faculty concerning educational measurement. Of particular interest is the discussion of standardized testing. (SLD)
