Documents a case of model-building in biology through microanalysis of one student's interaction with "Science for Living: The Circulatory System (SFL)", an interactive multimedia resource prototype for research. Describes the student's learning goals, gains, and activities with particular attention to interactions with representations,…

Compares sixth-grade American students to three samples of (Chinese, Japanese, and Taiwanese) sixth-grade Asian students to determine if the well-documented mathematical achievement of students from these Asian nations might be due in part to a greater understanding of mathematical representations. Indicates that all Asian samples scored…

Examines the usefulness of the Eisenberg-Berkowitz Information Problem-Solving model as a categorization for academic reference encounters. Major trends in the data include a high proportion of questions about location and access of sources, lack of synthesis or production activities, and consistent presence of system problems that impede the…

Analyzed 1.5- and 2.5-year-olds' problem solving and learning. Found that changes in toddlers' strategies could be assessed reliably on a trial-by-trial basis, that changes followed the basic form predicted by the overlapping waves model, and that analyses could reveal information about the qualitative and quantitative aspects of their learning.…

This article describes a simple, concrete and engaging model for teaching self-determination skills (such as self-awareness, goal-setting, choice-making, problem solving and self-monitoring) to early elementary students. The model was designed to increase appropriate behaviors, academic performance and positive self-concept in students with and…

Chernyshenko, Stark, Chan, Drasgow, and Williams (2001) investigated the fit of Samejima's logistic graded model and Levine's non-parametric MFS model to the scales of two personality questionnaires and found that the graded model did not fit well. We attribute the poor fit of the graded model to small amounts of multidimensionality present in…

The National Research Council has suggested that science classes need to become more active and authentic. To help with this effort, Thayer Model Engineering was created several years ago as an inquiry science course at Champlain Valley Union High School in Hinesburg, Vermont. In this school, the students apply the Thayer Model--a four-step…

Traditionally, students learn arithmetic throughout their primary schooling, and this is seen as the ideal preparation for the learning of algebra in the junior secondary school. The four operations are taught and rehearsed in the early years and from this, it is assumed, "children will induce the fundamental structure of arithmetic" (Warren &…

Burleson and Goldsmith's (1998) comforting model suggests an appraisal-based mechanism through which comforting messages can bring about a positive change in emotional states. This study is a first empirical test of three causal linkages implied by the appraisal-based comforting model. Participants (N=258) talked about an upsetting event with a…

Recently we were presented with an interesting twist to the sliding ladder problem viewed in the related rates section of most calculus textbooks. Our problem concerning a sliding ladder that eventually hits the ground. At first, those attempting this problem fell into the calculus trap using only related rates. Previous work for this problem…

In this paper, we describe the skeleton of two teaching units, based on a Model for teaching mathematics, Context Orientated Teaching (COT). The first teaching unit concerns the proof of a mathematical proposition, while the second one concerns the solution of an open problem. Both are taught in the 10th grade, under the specific conditions of the…

Mathematical models have become an important tool for understanding the control of eye movements during reading. Main goals of the development of the SWIFT model (R. Engbert, A. Longtin, & R. Kliegl, 2002) were to investigate the possibility of spatially distributed processing and to implement a general mechanism for all types of eye movements…

This article proposes a theoretical framework for the identification and classification of the various processes that constitute Web-based education. The framework is based on the following premises: (1) Education may be regarded as a "corrective process," since it is aimed at bringing about a desired change in students' knowledge and…

Recent advances in our understanding of worry and generalized anxiety disorder (GAD) have led to the development of efficacious treatments for GAD. Although multidimensional treatment packages have shown efficacy, we know little about the efficacy and clinical utility of individual treatment components. This study evaluates the efficacy of…

Certainly, the process of decision-making and problem-solving in a shifting playing environment lies at the core of the Teaching Games for Understanding (TGfU) model. What is not clear is how, at the time of decision-making, players' feelings or affective factors and their subsequent influence on thinking, influence these processes. Affect has a…
