In problem-solving research, insights into the relationship between monitoring and control in the transfer of complex skills remain impoverished. To address this, in 4 experiments, the authors had participants solve 2 complex control tasks that were identical in structure but that varied in presentation format. Participants learned to solve the…

The role of causal beliefs in people's decisions when faced with economic problems was investigated. Two experiments are reported that vary the causal structure in prisoner's dilemma-like economic situations. We measured willingness to cooperate or defect and collected justifications and think-aloud protocols to examine the strategies that people…

Student involvement in their own assessment can add reflection and metacognition to the learning process. Based on this idea, an assessment instrument was developed to self-assess college students' mathematical problem solving tasks. The main objective of this exercise is to improve student learning. The assessment instrument contains three items:…

This article draws on Gee's notions of Discourse and specifically Discourse Models to explore Engineering Problem Solving1 and the different ways in which it can be understood in an engineering context. After Gee we attempt to identify aspects of doing, being and valuing that underpin people's Problem Solving Discourse Models. Interviews with…

This is a comprehensive study of the many facets of an entirely online organic chemistry course. Online homework with structure-drawing capabilities was found to be more effective than written homework. Online lecture was found to be just as effective as in-person lecture, and students prefer an online lecture format with shorter Webcasts. Online…

Students with specific learning disabilities (SLD) tend to have difficulty with reasoning and communication across many mathematical domains. The purpose of this study was, through open response questions, to examine the mathematics reasoning performance of 4 th grade students with SLD. Using the learner centered principles outlined by the…

The primary concern in current interaction design is focused on how to help users solve problems and achieve goals more easily and efficiently. While users' sufficient knowledge acquisition of operating a product or system is considered important, their acquisition of problem-solving knowledge in the task domain has largely been disregarded. As a…

\The purpose of this study was to investigate population invariance of the true-score linking functions with respect to the ability subgroups (i.e., average-achieving students, low-achieving students, and students with learning disabilities). The mean/mean linking functions for five alternate forms of a curriculum-based math problem solving…

In this study, the effectiveness of worked examples that emphasizes problem features (data type, number of groups, purpose of analysis) associated with specific problem types (t-test, chi-square, correlation) were examined on students' construction of problem schemata compared to traditional solution-only worked examples. A sample of 96 students…

This paper adds to a discussion initiated by Askew (2007) about two contrasting views of scaffolding; as a "tool for results" and a "tool-and-result". The study took place in four primary classrooms within a low socioeconomic setting. Two classroom episodes drawn from one of the teacher's classroom, illustrate the two different…

How can teachers ensure instruction is aligned with 21st century demands for self-directed, collaborative problem solvers? Practice exercises are not the answer. Instead, here's a book that explains why the key is to use explicit instruction that includes proficient models, specific feedback, and supportive coaching. Rhoda Koenig gives you insight…

This research explores how chief cabin crew members of major airlines made their decisions on-the-spot when they had unexpected problems. This research also presents some insights that may improve personnel training programs for future stewardesses and stewards based on the investigation of their decision-making styles. The theoretical framework…

The goal of this Statement on Competencies in Mathematics Expected of Entering College Students is to provide a clear and coherent message about the mathematics that students need to know and to be able to do to be successful in college. While parts of this Statement were written with certain audiences in mind, the document as a whole should be…

Thanks to technological progress the world becomes more and more complicated. People stand in front of new and difficult problems that need to be solved. These are problems, the solutions of which are not universal, and cannot be learned. Many solutions require specific data that cannot be learned, as new data is part of the ongoing generation of…

Since teachers always teach area and perimeter together--and they are both introduced soon after the definition of a rectangle--it is not surprising that students mix up the notions of area and perimeter. Changing the investigation on maximising the area of a fixed perimeter from the traditional, but boring, "Sheep pens" to the much more…
