Active learning approaches in mathematics education at universities in Oromia, EthiopiaAlemu, Birhanu Moges 11 1900 (has links)
Meaningful learning requires active teaching and learning approaches. Thus, with a specific focus on Mathematics teaching at university in Oramia, the study aimed to:
• examine the extent to which active learning/student-centered approaches were implemented;
• assess the attitudes of university lecturers towards active-learning;
• investigate whether appropriate training and support have been provided for the implementation of an active learning approaches
• assess the major challenges that hinder the implementation of active learning approaches and
• recommend ways that could advance the use of active learning approaches in Mathematics teaching at university.
A mixed-methods design was used. Among the six universities in the Oromia Regional State of Ethiopia, two of the newly established universities (younger than 5 years) and two of the old universities (15 years and older) were involved in the study. A total of 84 lecturers participated in the study and completed questionnaires. This was complemented by a qualitative approach that used observation checklists and interviews for data gathering: 16 lessons were observed while the lecturers taught their mathematics classes (two lecturers from each of the four sample universities were twice observed). In addition, semi-structured interviews were conducted with four mathematics department heads and eight of the observed lecturers. The study adhered to ethical principles and to applied several techniques to enhance the validity/trustworthiness of the findings. / Psychology of Education / D. Ed. (Psychology of Education)

Mathematical Pluralism: Constructive Mathematics and Economic TheorySteins, Stefan Arno 09 December 2021 (has links)
Wir schlagen eine praxisorientierte Explikation der philosophischen Position des Mathematischen Pluralismus vor. Dieser Position zufolge existieren mehr als ein legitimes mathematisches System. Wir interpretieren 'legitim' als 'geeignet zur Realisierung wissenschaftlicher Ziele' und wenden die resultierende pluralistische Position auf die Mathematische Ökonomie an. Wir präsentieren ein begriffliches Rahmenwerk, in dem pluralistische Thesen formuliert und evaluiert werden können, stellen ein informelles System der Konstruktiven Mathematik als Alternative zur Klassischen Mathematik vor, und zeigen, dass verschiedene ökonomische Theoreme nicht konstruktiv beweisbar sind. Auf dieser Basis argumentieren wir, dass Pluralismus relativ zu Zielen mit Bezug zu Erklärung und Simplizität in der Ökonomie vorliegt. / We propose a practice-oriented explication of the philosophical position known as mathematical pluralism. According to this position there exist more than one legitimate mathematical system. We interpret 'legitimate' as 'suitable for realizing scientific goals' and apply the resultant pluralist position to mathematical economics. We present a conceptual framework within which pluralist theses can be formulated and evaluated, introduce an informal system of constructive mathematics as an alternative to classical mathematics, and point out that central theorems of economic equilibrium theory are not constructively provable. On this basis, we argue that pluralism obtains with respect to goals related to explanation and simplicity in economics.
