Problem solving in chemical kinetics poses substantial challenges for university students since it often involves significant use of mathematics as a tool and language, with challenging translations and transitions between chemical phenomena and mathematical representations. In this paper, we present key findings from a study investigating…

This study explores the effects of a computer algebra system on students' mathematical thinking. Mathematical thinking is identified with mathematical thinking powers and structures. We define mathematical thinking as students' capacity to specialize and generalize their previous knowledge to solve new mathematical problems. The study was…

How is it possible to create and continuously improve a quality learning environment for our students? We present our one-year course on engineering thermodynamics as a case study in which we investigate the learning environment based on a competency model from the students' perspective. Based on the analysis of our course structure and exam…

The present short paper is an attempt in the direction of understanding the learning problems of undergraduate students. Sample of chemical engineering students was selected to perform a simple exam test. The test was divided into four steps. Closed book - individual student, Closed book - cooperative students, Open book - cooperative students,…

Students' epistemological beliefs are beliefs centred on one's own learning and knowledge. Such beliefs play a major role in the way one approaches problem solving in physics. The intention of this study is to evaluate such beliefs amongst undergraduate physics students. An analytical tool developed by Hammer has been used as a criterion for…

A practical for students to experience a process plant is presented, based on operating a solvent absorption plant for carbon dioxide capture. The student must operate the plant in assigned roles that closely identify with a chemical plant environment, to achieve specific performance targets. Students must overcome technical challenges that…

This article presents and discusses the results of an educational innovation that seeks to introduce the world of molecular gastronomy in chemistry lessons as a means to review stoichiometry and offer an alternative way to learn. In the literature to date, there is no evidence of haute cuisine having been employed to contextualize stoichiometry…

A concern in engineering education is students adopting a 'recognise and reproduce' approach to problem solving. In this study, an assignment was conceived and analysed through Legitimation Code Theory -- which allows for visualisation of students' thinking, and to illuminate how students construct knowledge in open-ended problem solving. The…

Background: It is widely known that for many students it is very difficult to correctly predict how thermal expansion affects the appearance of a metal plate with a circular hole. Interviews with school teachers show that the source of this difficulty could stem from the fact that students' internal visualizations of an arbitrary object's thermal…

Future global challenges that engineering graduates face have placed demands on engineering education and how graduates develop competency in collaborative problem-solving. Such demand has seen an increase in the use of pedagogies like problem-based learning (PBL) that provide opportunities for developing collaborative problem-solving skills. PBL…

The engineering graduate of today will engage in a career which will span the middle of the twenty-first century, and beyond. They will work in a world which is increasingly more complex and uncertain than at any time before. This will require an integrated combination of technical knowledge and transferable skills and values, to a greater extent…

Entropy is a central concept in thermodynamics, but has been found to be challenging to students due to its abstract nature and the fact that it is not part of students' everyday language. Interviews with three pairs of engineering students (N = 6) were conducted and video recorded regarding their interpretation and use of the entropy concept, one…

This paper pursues to define the pillars for designing the specific (SC) and optional curricula (OC) of Unit Operations and Processes (UOP) Discipline in the Chemical Engineering Program. To achieve this objective a methodology was developed, which was characterized by the participation of every member in the educational process: professors,…

Background: This article reports on an analysis of errors that were displayed by students who studied mathematics in Chemical Engineering in derivatives of mostly trigonometric functions. The poor performance of these students triggered this study. The researcher (lecturer) works in a mathematics support programme to enhance students'…

This article describes two approaches to learning (in addition to the classic deep and surface approaches) identified in studies of student learning in engineering contexts. The first study identified the 'procedural deep' approach in a group of engineering foundation programme students in the UK, while the second study identified the 'procedural…
