The purpose of my study was to describe the manner in which Grade 9 technology learners typically accessed and used information sources during the early phases of their design processes. I did this by using an Extended Cognition framework to study the internal and external information sources that learners typically accessed and used in a technology learning environment. Theoretically, my study aimed to develop the application of the Extended Cognition Theory in an educational context. In this manner, my study adds to the scarce literature on design cognition in technology education. The methodological purpose of this study was to adapt conventional Think Aloud Protocol methods (TAPS) to investigate groups of learners in their natural technology learning environment. This methodology enabled me to understand the link between theoretical and empirical approaches of design cognition. As such, I was able to conceptualise practical guidelines that could be used by technology lecturers and teachers for the effective facilitation of the early phases of design processes. The conceptual framework of my study was adapted from empirical studies of expert designers, and is underpinned by the Information Processing and Embodiment theories. I followed a concurrent mixed methods approach and employed a case study design applying pragmatic assumptions. The target population for this study comprised Grade 9 learners based in a low socio-economic region. Eight female participants were purposefully selected and conveniently clustered into three groups: two groups of three participants, and one group of two participants. Data collection therefore consisted of three separately video recorded protocol studies. I was able to elicit the information access and usage activities of the participants by providing them with a design task that I adapted from a prescribed textbook, as suggested for technology by the Department of Basic Education. During the video recordings of the participants’ design processes, I was able to collect concurrent verbal, visual and temporal data types. I analysed the data according to a five-level framework, also adapted from the empirical investigations of expert designers. During my quantitative data analysis, I identified the occurrences of each group of participants’ cognitive phases, as well as the occurrences of their information access and use activities during each cognitive phase. On the one hand, problem structuring did not occur regularly. However, during their problem structuring activities, the participants mainly accessed and used instructions contained in the design task and pictures. On the other hand, the participants predominantly exhibited problem solving cognitive phases in which they mainly accessed and used external information sources including pictures and sketches. During my qualitative data analysis, I traced how the participants transformed their understanding of the design problem and possible design solutions. During problem structuring, the participants accessed information about the users’ needs, the design context and design objectives by perceiving and recognising useful information in their design task instructions and pictures. Information use during problem structuring was evidenced when the participants transformed information that they accessed to propose design objectives, constraints and requirements. Accessed information was typically transformed when the participants: (1) Read/evaluated information from the design task; (2) Evaluated the problem/context; (3) Evaluated/Elaborated information about the design objective; (4) Justified a design requirement; (5) Proposed/justified a design constraint; (6) Evaluated/Elaborated available resources in the environment; (7) Elaborated on the design context. During problem solving, the participants accessed information about the function, behaviour and structure of possible design solutions by perceiving and recognising useful information, primarily in their sketches, 3D models and pictures. Information use during problem solving was evidenced when the participants transformed accessed information to propose design specifications and limitations. Accessed information was typically transformed when the participants: (1) Evaluated existing solutions; (2) Proposed design limitations; (3) Modified existing solutions; (4) Proposed/evaluated a design idea; (5) Elaborated on a design idea; (6) Justified ideas; (7) Qualified ideas; (8) Modified previous design ideas. From the findings of my study, I could develop practical guidelines for current and future technology teachers. These guidelines should help technology teachers to effectively facilitate information rich design thinking during the early phases of learners’ design processes. I conclude this study by reiterating that the participants’ design cognition was enhanced by the availability of various information sources. This implies that technology teachers play a central role as information providers and mediators. Failure to provide adequate information sources during design tasks might inhibit learners’ development of the proficient design skills intended by the technology Curriculum and Assessment Policy Statement (CAPS) document. / Dissertation (MEd)--University of Pretoria, 2015. / National Research Foundation (NRF) / Science, Mathematics and Technology Education / MEd / Unrestricted
