Two analyses of variance (ANOVA) models for item scores are compared. The first is an items by subject random effect ANOVA. The second is a mixed effects ANOVA with items fixed and subjects random. Comparisons regarding reliability, Cronbach's alpha coefficient, psychometric inference, and inter-item covariance structure are made between the…

A study examined how many and what kind of questions appear in elementary science and social studies textbooks and teachers' manuals. Approximately 7500 questions from fourth and fifth grade science and social science textbooks from three major publishers were classified according to the following characteristics: (1) type of cognitive demand; (2)…

In a study of memory use in language comprehension, 84 second grade, 54 sixth grade, and 54 college students produced elaborations on sentences. In a context elaboration, task students put sentences in different contexts, and, in a causal inferencing task, they inferred alternative reasons for events. Language understanding was measured by the…

The use of computers to build diagnostic inferences is explored in two contexts. In computerized monitoring of liquid oxygen systems for the space shuttle, diagnoses are exact because they can be derived within a world which is closed. In computerized classroom testing of reading comprehension, programs deliver a constrained form of adaptive…

Teachers' knowledge and understanding of classrooms is perceived in this study in terms of interpretation of non-verbal and situational cues. Two sets of videotapes of classroom episodes were prepared, one in Hebrew and one in Dutch. These tapes were viewed by Israeli and Dutch teachers in cross-cultural settings. Teachers responded in writing and…

Working on the assumption that story structure contributes to the reading comprehension of students, a study assessed the comprehension and recall of 12 seventh and eighth grade remedial reading students. Subjects read a basal story revised to conform to a familiar story grammar and the original, unrevised, basal story. The two original stories…

Knowledge elicitation through programming was studied to determine students' intuitive ideas about motion. The subjects, 17-year-old sixth-form science students and 14-year-old third-form students, were asked to write expert systems programs about motion; and their interactions with their own knowledge were observed. The 17-year-old students had…

A subset of Statistical Process Control (SPC) methodology known as Control Charting is introduced. SPC methodology is a collection of graphical and inferential statistics techniques used to study the progress of phenomena over time. The types of control charts covered are the null X (mean), R (Range), X (individual observations), MR (moving…

This research investigated college students' attitudes toward allegations of sexual harassment involving college instructors and students. A procedure was developed that could be administered in a single class session, aimed at increasing students' understanding of the conditions under which causal inferences are appropriate, sensitizing them to…

The process of introducing students to alternative approaches and giving them the opportunity to debate their views about a work in order to develop critical thinking skills can start in the elementary school grades. George Hillocks' seven-level hierarchy represents an appropriate scheme by which teachers can sequentially move students to higher…

In a study of children's moral development, four toddlers and their mothers were observed at home approximately every three weeks when toddlers were 13-23 months of age. Six behavioral signs of children's awareness of standards were coded: (1) proud looks, achievement smiles, statements of accomplishment; (2) awareness of, interest in, and…

Authors who write introductory business statistics texts do not agree on when to use a t distribution and when to use a Z distribution in both the construction of confidence intervals and the use of hypothesis testing. In a survey of textbooks written in the last 15 years, we found the decision rules to be contradictory and, at times, the…

Suggests that business communication curricula should include instruction in critical thinking, and offers ways in which students can practice their critical thinking skills using business curricula. (JC)

Among kindergarten children, second-, fifth-grade, and college students, a gradual age-related increase was found in the ability to interpret an event from another person's perspective in light of that person's prior experiences. Various alternative explanations for the developmental trend were evaluated with data from subjects receiving prompts…

Proposes and tests an attributional model of parent social cognition and examines parents'inferences about why everyday child behaviors occur and what consequences these inferences may have for socialization. (HOD)
