This study explores volitional and affective responses to instructional activities aimed at developing geometric and spatial vocabulary of a neurodivergent student. Using teaching experiment methodology across 15 instructional sessions, we observed how the student responded to games, direct instruction, and vocabulary support embedded in spatial…

Statistical terms are used in everyday language and, at times, used in non-statistical ways. It is often assumed students understand statistical terms because of their common use; however, research into their understanding of specific statistical terms is scant. This report focuses on 58 Year 3 students' responses to the basic question, "What…

Research on scientific reasoning plays an essential role at the intersection of cognitive development and science education. As only few paper-pencil-tests exist to assess scientific reasoning abilities of elementary school children, the goal of the current study was the development of a new reliable and valid instrument. We focused on the…

The present study compared item and ability invariance as well as model-data fit between the one-parameter (1PL) and three-parameter (3PL) Item Response Theory (IRT) models utilizing real data across five grades; second through sixth as well as simulated data at second, fourth and sixth grade. At each grade, the 1PL and 3PL IRT models were run…

The unidimensionality of the reading and mathematics tests of the California Assessment Program was investigated. During April of 1980, all third grade students in California took a test consisting of reading, mathematics, and written language items. Item intercorrelation matrices were constructed for each skill, and the latent roots extracted.…

This study tested the following hypotheses: (1) that children would use both verbal-associative and acoustic memory attributes when encoding words in memory, and that the recall of younger children would indicate dominance of the acoustic attribute while the recall of older children would indicate dominance of the verbal-associative attribute; (2)…

To examine the role of friendship among children involved in potential conflicts, 37 aggressive, 37 non-aggressive, and 76 "intermediate" third- and fifth-grade boys were presented with a variety of potentially conflictual situations, nine in story form and one involving a contest. Each situation involved a negative or ambiguous outcome…

This study, which was concerned with the ways in which actions can be elaborated and can influence children's awareness of actions, examined the relationship between action and awareness during childrens' performance on the Towers of Hanoi problem. A total of 94 children between the ages of 6 and 8 years were asked to solve a three-disc version of…

Ninety children in third and fourth grade were assessed on a hierarchical class inclusion task. Scores were trichotomized, and children from each level were randomly assigned to one of three cueing conditions (no cues, two superordinate cues, six subordinate cues). Subjects were administered a recall task of categorized words and "new" words…

In a teaching experiment, I examined a theoretical model of mathematics teaching and learning in practice. In this paper I focus on how the model can guide the teacher's thinking about students' understandings and the generation of activities that foster intended transformations in those understandings. As a research-teacher I taught, twice a week…

Mikhail Bakhtin's understanding of the medieval carnival--a time when life is turned upside down, social hierarchies are lifted, and the lines between performer and participant are blurred--provides a useful framework for understanding both liberatory and potentially threatening aspects of writing workshops in elementary schools. An experimental…

Person fit in the Rasch one parameter model is investigated. The first set of data deals with grade 3 students responding to the mathematics computation and reading vocabulary subscales of the Comprehensive Test of Basic Skills Forms (CTBS/S). The second set of data deals with grade 3 students responding to the Basic Skills Assessment Program…

This experiment tested the hypothesis that the sequence of ability and effort attributional feedback influences children's attributions, self-efficacy, and skillful performance. Children deficient in subtraction skills received training on subtraction operations and solved problems over four sessions. During the problem solving, some children…

The psychometric characteristics of constructed response items referring to choice and nonchoice passages administered to approximately 150,000 students in grades 3, 5, and 8 were studied through item response theory methodology. Results indicated no consistent differences in the difficulty and discrimination of items referring to the two types of…

The influence of intelligence, self-concept, and causal attributions on metamemory and the metamemory-memory behavior relationship in grade-school children was studied. Following the assessment of intelligence, self-concept, and causal attributions, 105 children each from grades 3, 5, and 7 were given a metamemory interview and a sort-recall task.…
