This study explores the use of the Adaptive Neuro-Fuzzy Inference System (ANFIS), a neuro-fuzzy approach, to analyze the log data of technology-based assessments to extract relevant features of student problem-solving processes, and develop and refine a set of fuzzy logic rules that could be used to interpret student performance. The log data that…

Most models of human performance on the traveling salesperson problem involve clustering of nodes, but few empirical studies have examined effects of clustering in the stimulus array. A recent exception varied degree of clustering and concluded that the more clustered a stimulus array, the easier a TSP is to solve (Dry, Preiss, & Wagemans,…

A complete, non-trivial, traveling sales tour problem contains at least one "indentation", where nodes in the interior of the point set are connected between two adjacent nodes on the boundary. Early research reported that human tours exhibited fewer such indentations than expected. A subsequent explanation proposed that this was because…

The principle of "inversion," that a + b - b "must" equal a, is a fundamental property of arithmetic, but many children fail to apply it in symbolic contexts through 10 years of age. We explore three hypotheses relating to the use of inversion that stem from a model proposed by Siegler and Araya (2005). Hypothesis 1 is that…

Leadership is a highly complex activity, as leaders respond to increasing diversity and external accountability. Additionally, there is increased recognition that leadership is deeply contextual, sensitive to macro-politics of systems and micro-politics of individual schools. In Ontario, Canada, the school improvement effort is focused on raising…

Canada's knowledge-based economy--especially the fields of science, technology, engineering and mathematics (STEM)--continues to grow. Related changes in the economy, including shifts to globalized markets and an emphasis on innovation and technology, all mean that education is more and more an integral component of economic and social well-being.…

The Association for the Advancement of Computing in Education (AACE) is an international, non-profit educational organization. The Association's purpose is to advance the knowledge, theory, and quality of teaching and learning at all levels with information technology. "EdMedia + Innovate Learning: World Conference on Educational Media and…

The Program for International Student Assessment (PISA) is a system of international assessments that allows countries to compare outcomes of learning as students near the end of compulsory schooling. PISA core assessments measure the performance of 15-year-old students in mathematics, science, and reading literacy every 3 years. Coordinated by…

This is a condensed report of a study commissioned by the Minister's Advisory Committee on Student Achievement (MACOSA). The study was designed to provide information about current levels of achievement in mathematics among students in Alberta schools and to provide a data base for future assessments. The test was given to third-, sixth-, ninth-,…

In Alberta, 167 elementary students completed an awareness of technology survey in years 1 and 3 of a study. Even before technology education, children had ideas about testing structural strength. Development of testing knowledge was not sequential. Results may have been influenced by the various ways design technology was taught during year 2.…

The performance-based assessment was developed to assess students' higher order thinking skills in real-life problem-solving situations in Alberta, Canada. These tasks assess aspects of science that cannot be measured easily by regular paper and pencil tests. The purpose of this document is to provide teachers, administrators, students, and…

Thirty-six testwise and 41 test-naive high school seniors in British Columbia (Canada) were tested to determine their abilities to apply selected test wiseness principles according to a proposed model of test-taking behavior. To apply the testwiseness strategy, students first needed knowledge of the content tested and test item content. (SLD)

Analysis of response strategies employed by 261 undergraduate chemistry students when answering multiple-choice and stem-equivalent constructed-response questions revealed no significant differences in types of solution strategies or types of errors across test format. However, analysis of student oral reports revealed a higher frequency of…

Statistical data and comments describe the results of the 1977 eighth grade testing program in Ontario, Canada. The tests were: Mathematics (in French and English), Problem Solving (in French and English); Science (in English only), Attitudes, French Comprehension, and Written English. Table 1 presents the numbers of students, by school district,…

A series of tests was administered to Ontario, Canada students who had completed the eighth grade: mathematics, reading, language, written English, social studies, science, health, physical fitness, French as a second language, French as a first language, written French, values, moral reasoning, problem solving, and attitudes. Approximately 50…
