This article explores how differences in problem representations change both the performance and underlying cognitive processes of beginning algebra students engaged in quantitative reasoning. Contrary to beliefs held by practitioners and researchers in mathematics education, students were more successful solving simple algebra story problems than…

The effects of dissonant and consonant music on cognitive performance were examined. Situational dissonance and consonance were also tested and determined as the state where one's opinion is contrasted or matched with the majority's opinion, respectively. Subjects performed several cognitive tasks while listening to a melody arranged dissonantly,…

This study examined relationships between cognitive functioning in older people and (1) levels of mental, physical and social activities, and (2) intentions regarding maintenance of cognitive functioning. Participants (N = 145) were 70-91 years of age, varied in health status and socio-economic backgrounds. Current cognitive functioning was…

Many believe that girls lack the confidence and motivation to persist with computers when they face a challenge. In order to increase the number of girls and women in information technology careers, we need a better understanding of how they think about and solve problems while working on the computer. In this article, we describe a qualitative…

This article reviews the assessment data, literature and research on gender differences in mathematics. The question of whether boys are better at mathematics has been an issue in education for the past 5 years. The assumption is that there is a biological difference between boys and girls that make boys predisposed to do better in mathematics.…

This authoritative guide addresses all aspects of school psychology practice in a response-to-intervention (RTI) framework. Thirty-four focused chapters present effective methods for problem-solving-based assessment, instruction, and intervention. Specific guidelines are provided for promoting success in core academic domains--reading, writing,…

Problem-posing abilities of 54 third graders who displayed different patterns of achievement in number concepts and novel problem solving were investigated in this paper. The children were administered a problem-posing pretest followed by an instructional program (for half the sample) and a delayed posttest. Among the findings are the limited…

By using ill-structured problems and examining problem- solving processes, this study was conducted to explore the nature of solving complex, multistep problems, focusing on how prior knowledge, problem-solving process utilization, and analogical problem solving are related to success. Twenty-four college students qualified to participate by…

This book aims to enlighten its readers on how to achieve optimal human efficiency, well-being, and balance through "brainwave training." According to the book, the 4 kinds of brainwaves--beta, alpha, theta, and delta--communicate with each other to pass information between conscious and unconscious mind. Mastering these brainwaves…

At present, there are no formal tests to assess adequately the ways in which a child processes information. Furthermore, scores on current measures cannot be directly interpreted, with few exceptions, as direct measures of cognitive processes, and results are difficult to translate directly into remediation goals or instructional objectives.…

The role of planning in the design of digital circuits was studied in two experiments. One compared the planning-related activities of expert designers and beginning students of design, and the other looked at the effect on circuit-design processes of forcing students to construct a global plan. In experiment 1, five undergraduate students…

The research described in this paper leads to an instructional design approach which is an alternative to the consideration of such issues as mathematical skills or level of cognitive development. The approach uses an analysis of traditional instructional tasks to specify the underlying cognitive processes and structures necessary for the…

The major purpose of a study was to identify the knowledge, skill, and cognitive process differences between expert and novice technicians on technical troubleshooting tasks. Identification of these differences was conducted through two investigations. Investigation 1 sought to describe differences in the declarative and procedural knowledge bases…

This study investigated how people reason about simple mechanical devices and physical systems, and how reasoning methods and understanding of a device evolve over a period of exposure. Twelve students attending the Teachers College at Columbia University (New York) participated in the first of two experiments; and 10 students attending the same…

The literary field offers an especially rich array of examples of the insight phenomenon and demonstrates that insight experiences occur outside the problem-solving paradigm of cognitive science. Analysis shows that the seemingly unitary moment of insight is actually a microgenetic sequence (a rapid sequence of developmental change) deeply…
