1. Developing Mindsets: A Qualitative Study among First-Year South African University Students

Author

Terblanche, Hettie, Mason, Henry, and Van Wyk, Barend

Abstract

This article reports on a qualitative study that evaluated first-year students' lived experiences of attending a 12-week student support programme focused on fostering mindsets. Participants included 545 first year Engineering students enrolled for academic studies at a South African university. All participants completed qualitative narrative sketches depicting their experiences. A random sample of 300 students' narrative sketches was included as data in the qualitative study. The data were analysed using thematic analysis, and Dweck's theory on mindsets served as the theoretical lens through which the data were interpreted. The results indicate that the majority of students experienced significant personal growth from attending the student support programme. Additionally, the findings point to the relevance and importance of offering student support programmes focused on exploring mindsets to first-year students. The results of this exploratory study suggest that mindset theory should be considered as an essential component when advising first-year South African Engineering students. Furthermore, we make a case for the relevance of positive psychology-based development programmes for first-year students.

3. The Influence of Learning and Study Strategies Inventory on the Success of Engineering Students at a South African University of Technology

Author

Van Wyk, Barend and Mason, Henry D.

Abstract

This article reports on a study investigating the relationship between university students' self-reported use and application of learning and study strategies and student success indicators (timeframe and student type, namely low-performing, average-performing, or high-performing). Participants were 1,439 engineering students enrolled for academic studies at a South African University of Technology (UoT). Data were collected using the Learning and Study Strategies Inventory (LASSI) and academic performance data, obtained via the university's student management information system. The LASSI provides diagnostic information about students' self-perception regarding their study skills and learning orientations, assists educators in designing interventions for students to improve their skills, and aids in predicting academic achievement. Researchers have questioned the long-term correlation between LASSI scores and academic performance. Our results confirm that time spent in the tertiary environment and student type (low-, average- or high-performing) should be considered when using LASSI as a diagnostic tool. The usefulness of using the Credit Accumulation Rate (CAR), a measure that combines time spent in the tertiary environment and academic performance, is introduced and explored. Some novel trends emerged by investigating the relationships between CAR and LASSI scores. Based on our results, we make recommendations for identifying students at risk for academic failure and propose avenues for further research.

6. The Sense of Agency in Human–Machine Interaction Systems.

Abstract

Human–Machine Interaction (HMI) systems are integral to various domains and rely on human operators for effective performance. The sense of agency (SoA) is crucial in these systems, as it influences the operator's concentration and overall efficiency. This review explores the SoA in HMI systems, analyzing its definition, key influencing factors, and methods for enhancement. We provide a comprehensive examination of SoA-related research and suggest strategies for measuring and improving the SoA. Two key research directions are highlighted: the impact of user experience on the SoA, and the role of the SoA in enabling unconscious communication between humans and machines. We propose a development route for HMI systems, outlining a progressive structure across three stages: machine-centric, human-centric, and human–machine integration. Finally, we discuss the potential of gaming platforms as tools for advancing SoA research in HMI systems. Our findings aim to enhance the design and functionality of HMI systems, ensuring improved operator engagement and system performance. [ABSTRACT FROM AUTHOR]

7. Time-Delay Estimation Improves Active Disturbance Rejection Control for Time-Delay Nonlinear Systems.

Abstract

Lately, active disturbance rejection control (ADRC), a model-independent controller, has become popular for combating various forms of uncertain disturbances incurred in industrial applications. ADRC was validated for external disturbances, internal disturbances, and nonlinearities incurred under realistic scenarios. Time delay challenges all controllers, especially when it coexists with nonlinearities. This paper investigates the impacts of time delay and backlash-like hysteresis nonlinearity in ADRC-controlled systems. These impacts are analyzed, as in the case study, in two ADRC-based methods, namely the ADRC with delayed input method and the predictive extended state observer (PESO)-based ADRC (PESO-ADRC) method. To improve the system response and to attain a decent attenuation of uncertainties, the time-delay estimation (TDE) mechanism is introduced to the concerned ADRC-based methods. Experimental studies are conducted to verify the effectiveness and stability of the proposed TDE-ADRC methods. The results demonstrate the robustness and decent recovery of the transient response after the adverse impact of the backlash-like hysteresis on both concerned ADRC-controlled systems.

20. Mathematics: A Powerful Pre- and Post-Admission Variable to Predict Success in Engineering Programmes at a University of Technology

Author

van Wyk, Barend, Hofman, Wiecher, and Louw, Cecilia

Abstract

Although student attrition and retention are researched all over the world, there is no final formula available to ensure academic success for selected students. The purpose is to share research undertaken at the Tshwane University of Technology (TUT) in order to investigate the role of mathematics in student achievement and retention in National Diploma engineering programmes. This study contributes to the identification of key aspects that exercise an influence on success at a University of Technology (UoT) in a country where students have diverse schooling experiences. An ex post facto study was carried out on a sample drawn from the first-time-entering National Diploma cohorts of 2009 and 2010 to determine a possible correlation between their National Senior Certificate (Grade 12) mathematics performance and their first semester mathematics performance, or with their first semester mathematics performance and the number of subjects passed after two years of study. The results indicate that the performance in Mathematics I has a better predictive value than any other variable investigated. The performance in Mathematics I may therefore be used as part of an early warning system for dropping out and in determining the size and nature of the support structures needed. Mathematics performance during the first semester at TUT is a significant determinant of academic success for National Diploma students in engineering disciplines.

Subjects
Artificial intelligence, Artificial intelligence -- Research
Abstract

A novel Projections Onto Convex Sets (POCS) graph matching algorithm is presented. Two-way assignment constraints are enforced without using elaborate penalty terms, graduated nonconvexity, or sophisticated annealing mechanisms to escape from poor local minima. Results indicate that the presented algorithm is robust and compares favorably to other well-known algorithms. Index Terms--Graph matching, subgraph matching, contextual correspondence matching, projection onto convex sets.
