This study examined changes in personal science teaching self-efficacy (PSTE), outcome expectancy (STOE), and science conceptual understanding and relationships among these in preservice teachers. Seventy preservice teachers enrolled in science teaching methods courses participated in this study. PSTE, STOE, and science conceptual understanding…

Two studies investigated the effectiveness of the A-Priori reading intervention program, which uses pre-teaching in an effort to provide at-risk students (who qualify for the Chapter 1 program) with prior knowledge before the regular instruction on the same objectives and topics. In the first study, subjects were a control group of 207 students in…

This publication highlights three topics from the 1992 National Institute on the Assessment of Experiential Learning. "Computer Conferencing at the National Institute: The Articulation of Knowledge and Writing Ability in the Assessment of Experiential Learning" (Evelyn F. Spradley) discusses the electronic conference held concurrently with the…

Interactive multimedia programs have found their way into the hands of young children. This case study attempts to determine how two year old children interact with interactive multimedia technology, and addresses the following questions: is it appropriate to include the interactive multimedia technology in the same context as other objects like…

This paper discusses various aspects of conceptual change instruction and research related to conceptual change strategies. The role played by teachers in the conceptual change process has been neglected in the research and understanding that role requires that: (1) the Conceptual Change Model of Posner provide a reasonable framework for thinking…

A study examined the role of prior knowledge in teacher-generated analogies and student-generated analogies that convey the concept of protein synthesis. Subjects were 269 eighth-grade students enrolled in a public school district in a northern suburb of Chicago, Illinois. Subjects were divided into groups that received traditional instruction,…

A study examined the predictive validity of two methods of prior knowledge assessment: free association and prediction. Subjects, 72 sixth graders from suburban public and private schools, were divided into four groups: standard free association; standard free association plus prediction; definitional free association; and definitional free…

A review was conducted of the research related to the ability of elementary school children to carry out search tasks with informational text. The review was organized within a framework of components of the search process: goal formation, text selection, information extraction and integration, and evaluation. The research reviewed suggests that…

A study involving 120 undergraduate students attending the University of St. Thomas in St. Paul (Minnesota) was undertaken to test the interactive effect of instructional strategy (structured versus constructed) with learner's prior domain knowledge in concept acquisition. Previous instructional design research on concept learning has focused on…

Concerns about students' difficulties in statistical reasoning led to a study which explored year 11 (14 to 16 year-olds) students' ideas in this area. The study focussed on sampling variability, probability, descriptive statistics and graphical representations. This paper presents and discusses the ways in which students made sense of sampling…

This review of the research on aptitude-treatment interaction (ATI) discusses four methods or assumptions that might explain why ATI research has not generated the anticipated empirical support: (1) the lack of a theoretical base; (2) disagreement over what a given aptitude means and how it should be measured; (3) difficulties in defining…

How background knowledge of the content of a text affects reading comprehension and the role it plays in the diagnosis and instruction of reading comprehension skills for linguistically/culturally diverse (L/CD) students may be demonstrated through schema theory. Since a schema represents what is believed to be generally true about a class of…

Noting that many prereading discussions lead teachers to "mis-estimate" students' prior knowledge about a particular topic, this paper describes the Pre-Reading Plan (PReP) designed to help both students and teachers become aware of what students already know about a specific topic. Following an introduction, the first portion of the…

A re-analysis of data from a previous study was undertaken to determine if student essays catagorized as dealing with group-phenomenon events differed in quality and syntactic complexity from essays categorized as dealing with individually experienced events. The essays of 44 college freshmen in basic writing classes were catagorized as dealing…

A nonequivalent control group design study, with a math unit on ratio and proportion as the treatment, was conducted to examine the validity of some written tasks as a measure of formal reasoning. Subjects in the study were 68 fifth grade students who enrolled in two classes in a small urban school. The experimental group learned a 12-lesson math…
