<p>User onboarding for Graphical User Interface (GUI) applications usually involve walkthrough tutorials explaining various UI elements, functions, and navigation screens. These First-time User Experiences (FTUEs) are crucial in determining any subsequent user interaction. The purpose of this study has been explored by eliciting answers to two research questions in specific. The study primarily investigates a user's perception of a tailored onboarding experience. Following this, the impact of these tutorials on the user's performance has also been used as a way to verify their effectiveness.</p> <p><br></p> <p>The emergence of educational crowdsourcing platforms has revolutionized traditional models of teaching and learning by engaging students in collaborative, real-world problem-solving activities. However, the success of crowdsourcing platforms in education largely depends on their ability to provide a positive and engaging user experience, particularly for first-time users. As a part of another ongoing study, the need for an engaging onboarding tutorial to educate users on the concept of worked-out examples and peer evaluations was evident. Thus, the interventions developed in this study are built upon a crowdsourcing platform designed to collect worked-out examples from university students. </p> <p><br></p> <p>Through a combination of qualitative and quantitative research methods, this study seeks to provide insights into the design of effective onboarding tutorials in the context of crowdsourcing educational resources. There have been numerous attempts to devise effective onboarding strategies. For instance, the interplay of narration and animation has been utilized as a way to gamify and design engaging FTUEs. The design choices for tailoring the experience were hence determined through Rapid Iterative Testing and Evaluation (RITE) methods. Analysis of the experimental data shows that there is a statistically significant improvement in the FTUE when users are presented with a tailored onboarding tutorial. Their usage patterns also tend to improve post their interactions with the tutorials. These results hope to contribute to a better understanding of user engagement in FTUEs, thus paving the way for furthering product adoption and value metrics on a broad scale.</p>

The aim of this study was to investigate the comparative effects of Constructivist-Based Teaching Method (CBTM) and the Traditional Teaching Method (TTM) on Grade 11 Mathematics learners’ errors in algebra. The constructivist learning theory (CLT) was used to frame this study. Mainly, CLT was used to influence the design of CBTI to hone participants’ errors in algebra that militate against their performance in Mathematics. The study was conducted in the Mpumalanga Province of South Africa with a four-week intervention programme in each of the two participating secondary schools. Participants consisted of n=78 Grade 11 Mathematics learners and one Grade 11 Mathematics teacher. A non-equivalent control group design consisting of a pre-test and post-test measure was employed. The Grade 11 teacher in the control school employed the TTM while the researcher implemented CBTM in the experimental school. The main aspects of CBTM entailed participants’ construction of their own knowledge from the base of prior knowledge and through group learning approach and exploratory talk in which discussions included argumentation, verbalising explanations, justifications and reflections. Participants in experimental school became familiar with the basic principles of CBTI such as group work, which enhanced the construction of conceptual understanding of algebraic concepts. This reduced most of the errors they commit in algebra and elevated their performance in Mathematics. The principal instruments for data collection consisted of a standardised Algebra Concept Achievement Test and lesson observations. The pre-test was used to determine participants’ initial errors in algebra before the intervention. A post-test was given at the end of intervention to ascertain change in participants’ errors in algebra over a four-week intervention period. Using descriptive and inferential statistical techniques, the study found that participants in experimental school significantly reduced their errors in algebra than those in control school. The study showed that CBTM was a more effective pedagogy that improved the errors Grade 11 learners commit in algebra than the TTM. / College of Education / M. Ed. (Mathematics Education)

The aim of this study was to investigate the effect of context-based problem solving instruction (CBPSI) on the problem solving performance of Grade 10 learners, who performed poorly in mathematics. A cognitive load theory (CLT) was used to frame the study. In addition, CLT was used to: 1) facilitate the interpretation and explanation of participants‟ problem solving performance; and, 2) influence the design of CBPSI to hone participants‟ problem solving skills. The study was conducted in the Gauteng province of South Africa and involved a two-week intervention program in each of the nine participating high schools. Participants consisted of 783 learners and four Grade 10 mathematics teachers. A non-equivalent control group design was employed, consisting of a pre- and post- measure. In addition, classroom observations and semi-structured interviews were conducted with teachers and learners. Teachers employed conventional problem solving instructions in four control schools while the researcher implemented CBPSI in five experimental schools. Instruction in experimental schools entailed several worked-out context-based problem solving examples given to participants in worksheets. The main aspects of CBPSI embraced elements of the effects of self-explanation and split-attention, as advocated by CLT. Due to the design of CBPSI participants in experimental schools became familiar with the basic context-based problem solving tasks that were presented to them through the worked-out example samples. In turn, the associated cognitive load of problem solving tasks was gradually reduced. The principal instrument for data collection was a standardized Functional Mathematics Achievement Test. The pre-test determined participants‟ initial problem solving status before intervention. A post-test was given at the end of intervention to benchmark change in the functionality of CBPSI over a two-week period. Using one-way analysis of covariance (ANCOVA), Analysis of Variance (ANOVA), and other statistical techniques the study found that participants in experimental schools performed significantly better than participants in control schools on certain aspects of problem solving performance. In addition, semi-structured interviews and classroom observations revealed that participants rated CBPSI highly. On the whole, the study showed that CBPSI is an effective instructional tool to enhance the problem solving performance of Grade 10 mathematics learners. / Mathematics Education / D. Phil.
