Information communication technology is capable of contributing supplementary teaching and learning strategies that can be used to address various educational challenges faced by higher education. Students who enter South African higher education institutions are often academically under-prepared and have not developed the cognitive skills required to engage in meaningful learning. When students build expert systems they are required to demonstrate the reasoning of an expert and to exhibit an understanding of causal relationships and procedural knowledge. This study formulated design principles in the form of conjectures and principles related to a learning environment that uses technology as a cognitive tool in the form of an expert system shell to promote higher-order thinking skills. The conjectures and principles formulated during this study are expressed in terms of the characteristics, procedures and arguments associated with a learning environment that uses technology in the form of an expert system shell to facilitate higher-order thinking. These conjectures and principles were separated into seven interrelated clusters: initial exposure, guided discovery learning, designing the expert system on paper, creating domain awareness, linking conceptual understanding to a representation of that understanding, hands-on development, and problem engagement.
Background: South Africa has incorporated Computer-Assisted Language Learning (CALL) into many university classrooms in order to help address ubiquitous concerns related to the limited English language proficiency of first-year university students. In the context of this study, the research site used the CALL application called the English Word Power (EWP programme). Research to establish students’ perceptions of the CALL application is somewhat limited, although students’ perceptions of a learning environment can be more useful in explaining their behaviour. Therefore, teachers’ understanding of the students’ perceptions towards a new learning programme is likely to assist them in tailoring the content according to the needs of the learners.Objectives: The objective of this study was to explore the students’ perceptions of the use of the EWP, a computer-based programme used for improving English language proficiency. The researchers endeavoured to gain an understanding of the students’ perceptions of the strengths and frustrations of the EWP programme. Specifically, the focus was on what the students perceived as their preferred mode of learning and what their views were regarding the contribution of the EWP programme in improving their language skills.Method: The study was qualitative in nature and a case study design was adopted. A purposive sample of 60 students from an Information and Communication Technology’s (ICT) Foundation programme was used to collect data. Focus group interviews were conducted with 60 purposefully selected students and content analysis was used to process data.Results: The study yielded mixed results, as some students were happy with some of the components of the EWP programme whilst others were frustrated with some components. Specifically, some students reported experiencing frustration with the irrelevant nature of the EWP content. On the contrary, the study revealed that students were satisfied with the EWP programme’s accessibility, which facilitated their learning opportunities. Some students reported that their language proficiency concerning spelling and vocabulary had improved. The findings further revealed that the students preferred face-to-face learning to the EWP programme learning environment.Conclusion: The implication of the findings is that students need a language learning programme that is relevant to their field of study. They also require a programme that allows for student–student and lecturer–student interaction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
