Teaching and Learning Review 2020
of continuous learning to create an environment in which students not only acquired content knowledge, but also developed graduate attributes and a professional skills set. One of the initiatives she used to create a continuous learning environment was the BA Bot for ISD students to access content and feedback on ISD topics. The idea of a knowledge conversion platform was born from Dr Hattingh’s own need to note information that was not captured in any textbook, but was required to complete the third-year capstone project. This platform was initiated through the integration of a commercially available bot platform and Google Drive. It allowed her to improve the second-year curriculum by making authentic case studies available that not only suited the teaching strategy of the Department but were easily accessible and contextualised within the South African environment. The platform could also be continually updated as more relevant case studies became available. The knowledge conversion model ensured that the BA Bot was populated with content to support scaffolded learning, starting at the data level, where key concepts and definitions were explained, working up to integrated examples. This platform enabled the teaching team to
provide students with various learning activities that catered for the different types of learning required by the context so that students could learn at their own pace. It also had the functionality to provide feedback, which was essential for effective learning.
Assessment Management System Undergraduate assessments in the field of engineering generally entail the systematic solution of problems of a mathematical nature. Such solutions often follow an algorithmic approach and are amenable to algorithmic evaluation. Over time, lecturers in the Department of Electrical, Electronic and Computer Engineering have been developing automated or semi-automated electronic grading systems. From 2017, these systems were consolidated into a comprehensive, web-based, mobile-friendly assessment management system, which could provide for several different assessment modalities. The assessment modalities can also be combined as required. By the end of 2019, this system had been used by over 4 500 students across several departments in the faculty.
A prime mover in this consolidation was Hans Grobler, a senior lecturer in the department, who developed an assessment management system that benefits students and lecturers alike. The motivation for the development of this consolidated system was the ever-growing class sizes in the faculty’s service modules, which have in excess of 300 students. For this reason, the first assessment modality, which was added in 2017, focused on the extraction and optical character recognition (OCR) of custom-designed forms. This allowed for the entirely automated assessment of tutorials, class tests, semester tests and examinations for large first- and second-year modules. The implementation of this system has had a positive impact on both student learning and teaching practice by enabling lecturers to grade analytical, mathematics-based assessments in a far more in-depth manner than would have been possible if they had been graded by hand. The system also automates mark management at assessment and module level. The assessment results and details of the marking process are made available to students via a web interface, and a query mechanism enables lecturers to respond to students’ queries and provide feedback.
