This study is a pre test-post-test experimental control group design having a goal to analyze the role of problembased learning on students' mathematical problem-solving ability (MPSA) and self-confidence (MSC). The study involves 66 tenth grade students, a mathematical problem-solving test, a mathematical self-confidence scale, and perception of…

These proceedings contain the papers of the 18th International Conference on Cognition and Exploratory Learning in the Digital Age (CELDA 2021), held virtually, due to an exceptional situation caused by the COVID-19 pandemic, from October 13-15, 2021, and organized by the International Association for Development of the Information Society…

The importance of computational skill for answering items in the quantitative thinking subtest of the Iowa Tests of Educational Development was investigated. Results show that computational skill is not a major factor contributing to the examinee's score on the subtest. (Author/GK)

The effects of two item formats on item difficulty and item discrimination indices for mathematics problem solving multiple-choice tests were investigated. One format required identifying the proper "set-up" for the item; the other format required complete solving of the item. (Author/JKS)

This study investigated the effects of specific criteria for marking a test on its reliability and validity. Eight algebra word problems were administered to grade 10 students. The objectivity of scoring criteria improved the reliability of the test, but did not affect its validity. (MNS)

Observing that available standardized tests purporting to measure problem solving in mathematics do not validly reflect currently accepted definitions of problem solving, while more valid individualized measures are costly in terms of time, this researcher undertook (1) to construct a paper-and-pencil instrument which might better reflect…

In this study the researcher investigated the feasibility of constructing a valid paper-and-pencil measure of problem solving ability. (Rationale and design of the study are discussed in Part 1.) The principal feasibility criterion, correlation of at least .71 with scores on taped and coded individual "thinking aloud" problem-solving…

This study involving 29 students enrolled in an 8-week summer Algebra II class for minority students was undertaken to determine the relationship between the kinds of symbolic forms used in problem-solving instruction and students' problem-solving processes and performance. All subjects were Black or Hispanic and were about to enter grade 11. For…
