Fostering critical thinking dispositions in the Technology classroom

Abstract

The purpose of this study was to investigate and describe how technology teachers foster a positive disposition towards Critical Thinking (CT) in their learners. One of the general aims listed in the South African National Curriculum Statement (NCS) specifically calls for the use of CT to enhance learners’ ability to identify and solve problems. In the Curriculum and Assessment Policy Statement (CAPS) for technology, CT is required to successfully solve problems during the design process. The design process, which is central to technology, thus offers many opportunities to nurture CT should teachers be willing to exploit them. CT consists of two components, namely, CT skills and CT dispositions. CT skills refer to the cognitive abilities of a person, while CT dispositions are concerned with an individual’s internal motivation to think critically. A fair amount of research regarding CT focuses on CT skills. The limited research available on CT dispositions reports mostly on its definition, classification, and assessment. The paucity of literature on CT dispositions suggest that teachers cannot draw from existing literature to inform their practice regarding the ways in which one could foster a willingness to think critically. This study, therefore, aimed to improve our understanding of the strategies used by technology teachers to promote CT disposition. The conceptual framework for this study was based on Facione’s (2011) seven dispositions towards CT, and was augmented by a description of the design process in technology education. The premise for using this framework is based on the assumption that if an individual is positively disposed towards CT, they will be inclined to critically solve the problems encountered during the design process in technology. The design process further presents the opportunity to nurture CT dispositions. This study engaged in a qualitative research approach and a multiple case study design to investigate how technology teachers foster CT dispositions in their learners. To this end, 10 senior phase technology teachers were purposefully selected and interviewed. The interviews comprised open-ended questions about each disposition to gain an in-depth understanding of the strategies that teachers use in their classroom. Five of these teachers were then observed for one design-based lesson to explore how these strategies are actualised in the technology classroom. The analysis of the interview data indicated that the participants used a variety of strategies to foster all the CT dispositions. These strategies were also noted during the observations, with no new strategies being revealed. The strategies included the use of assessments, discussions, the classroom environment, examples, feedback, modelling, questioning and resources. It was found that the participants used four main strategies as initial actions that acted as a platform for, or led to the use of supporting strategies to foster all of the CT dispositions. Through this study, some strategies that were identified in the literature regarding the nurturing of CT, its skills and dispositions were confirmed. Other strategies were identified as relating to the principles for teaching CT dispositions, while two strategies were recognised that were not mentioned in the literature. It is recommended that further research be conducted on the effectiveness of these strategies, learners’ experience of the strategies, and that longer periods of observation be done to include the facilitation of the entire design process. The research on CT dispositions up until this point has not suggested or described explicit strategies to specifically foster the dispositional component of CT. The findings and conclusions of this study are also not considered as the final answer to this paucity of literature, it does, however, pose as a departure point for further investigation and development.
