The relationships between ratings on the Idaho Alternate Assessment (IAA) for 116 students with significant disabilities and corresponding ratings for the same students on two norm-referenced teacher rating scales were examined to gain evidence about the validity of resulting IAA scores. To contextualize these findings, another group of 54…

There is much research that documents what many teachers know, that students struggle with many concepts in probability and statistics. This article presents two sample activities the authors use to help preservice teachers develop ideas about how they can use technology to promote their students' ability to understand mathematics and connect…

Models and modeling are frequently used as instructional tools in science education to convey important information concerning both the explanatory and structural features of topic areas in science. The efficacy of models as such rests almost entirely upon students' ability to conceptualize them as abstracted "representations" of…

Noting that although some children read aloud with apparent fluency, they fail to understand fully or remember connected discourse, this book brings together research on children who have a specific comprehension deficit. The book first provides an introduction and overview of adult and child text comprehension, and then describes the research.…

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…
