The international literature suggests students frequently resort to the use of formulae when solving stoichiometry problems without understanding the concepts. In prior work we identified Thai student alternative conceptions and ability to solve numerical problem for stoichiometry. The results indicate that many Thai students also hold alternative…

A continuing challenge to the undergraduate chemical engineering curriculum is the time-effective incorporation and use of computer-based tools throughout the educational program. Computing skills in academia and industry require some proficiency in programming and effective use of software packages for solving 1) single-model, single-algorithm…

We studied students' conceptions of correctness and their influence on students' correctness-related practices by examining how 159 students had analyzed the correctness of error-free and erroneous algorithms and by interviewing seven students regarding their work. We found that students conceptualized program correctness as the sum of the…

With the current focus in mathematics education on the importance of developing students' conceptual understanding, fluency with the language of mathematics, critical thinking, and working mathematically, teachers are constantly expected to design challenging and investigative tasks that can engage and motivate students in their learning of…

The intent of this paper is to sketch a conception of problem-finding and delineate the role of problem-finding in the solution of problems. (Author)

The universities and faculties which educate teachers of mathematics for teaching pupils/students of any age group from pre-school age to higher education carefully monitor and compare valuable results of this research, detect the areas in which the mathematical achievements of pupils should be improved at the national level and propose the ways…

In this study we investigated the effects of two treatments supplementing students' (16 to 18 years of age and in pre-university education) regular course in economics. One treatment, labelled concept treatment, aimed at the solidification of the students' knowledge about economic concepts and their interrelations. The other treatment, labeled…

In recent years more emphasis has been placed on conceptual learning and understanding in the sciences. Unfortunately, among advocates of such a position there are those who do not see any role for quantitative problem solving at the secondary/high school level or even the introductory university level. This may be due to the frequent use of…

This article focuses on the ways in which four eighth-grade girls, each with varying levels of algebraic understanding, share ideas, debate, and gradually move toward generalizations inherent in the "Painted Cube" problem. The intent of this article is to examine how students move to progressive formalization and to provide insights into the ways…

Teaching mathematics to students with emotional and behavioral disorders (EBD) is one of the most challenging tasks educators face today. Students with EBD are reported to have the most dismal outcomes of any other group of students with disabilities including the lowest grades, the most failing grades, higher retention rates, the highest dropout…

Article focused on ways in which anxiety influences behavior, particularly with respect to the influence of anxiety upon problem solving. (Author/RK)
