Comments (TM 503 706) on an earlier article (TM 503 420) concerning the comparison of the completely randomized design and the randomized block design are acknowledged and appreciated. In addition, potentially misleading notions arising from these comments are addressed and clarified. (See also TM 503 708). (Author/CTM)

This note continues the discussion of earlier articles (TM 503 420, TM 503 706, and TM 503 707), comparing the completely randomized design with the randomized block design. (CTM)

Investigated similarity of clinical evaluation of personological characteristics across three different information sources. Subjects were independently rated by a single clinician on 18 criterion factors in each of three information source catagories. Results indicate a varying degree of convergence of multitrait clinical ratings dependent on…

Limitations of student evaluations of college professors, such as variation according to favorableness of the learning situation, are identified. (GW)

Describes the Galileo system of measurement operations including reliability and validity data. Illustrations of some of the relations between Galileo measures and traditional procedures are provided. (MH)

Reports a class exercise which requires students to recalculate the Chi-squares, t-tests, and one-way ANOVAs found in published psychological research articles. Describes students' reaction to the exercise and provides data on the 13% error rate they discovered. (Author/JDH)

Two studies performed in secondary schools and at the University of Ottawa investigated the usefulness of Georges Henry's 1975 short readability formula, designed specifically for French, for evaluating instructional texts. (MSE)

Confirmatory factor analysis was applied to test second- and higher-order factor models in the areas of structure of abilities, allometry, and the separation of specific and error variance estimates. The estimation of validity and reliability, second-order models within factor analysis models, and the concept of discriminability were also studied.…

This paper examines the major methodological advantages of random assignment for the purpose of estimating the effectiveness of current manpower policy. It also reviews the claimed methodological and ethical objections to experiments. The authors argue that the offsetting gain from experimentation is the inherent reliability of experimental…

Selected literature related to faculty evaluations by students was reviewed. The psychometric properties of evaluation instruments were examined with particular emphasis on factors that affect validity. The findings suggest that caution should be exercised when interpreting student evaluations because their validity can be questionable. (MT)

Analyzes the implicit requirements for achieving reliable results from holistic ratings of writing samples and argues that these conditions bring the validity of the ratings into doubt. (HOD)

In an effort designed to guide and improve the assessment of a newly developed writing environment, the reliability and developmental and concurrent validity of a previously validated rubric developed for pen-and-paper-created narratives, Writing What You Read (WWYR), was determined when applied to hypermedia-authored narratives of children in…

Herzog and Wallace (A. Herzog and R. Wallace, 1997) discussed a measure designed to assess the cognitive functioning of older adults who participated in the study formerly known as the Asset and Health Dynamics among the Oldest Old (AHEAD). The measure derived from four well-known tests of cognitive functioning, but improves on them by combining…
