Abstract
Content analyses of research in the literature of gifted education (Coleman, 2006; Rogers, 1999, 2006) has shown a consistent absence of research investigating methodology for instructing gifted students and for the development of expertise using new technologies. In this study, utilising electronic instructional delivery, an investigation was undertaken of the differential effects and appropriateness of matching the prior knowledge of the learner to the instructional method. Underpinned with a theoretical understanding of gifted education and cognitive load theory, a series of three experiments was designed and implemented to determine whether gifted students learn more effectively under guided discovery design than with example based instruction, while not identified as gifted ability students perform significantly better under direct example based instruction than with guided discovery. Data were collected and analysed in three stages. Experiment 1 was conducted in the novel domain of Boolean switching equations. Experiments 2 and 3 used identical test instruments with novel tasks in the semi-familiar domain of geometry. A total of 155 Years 7, 8 and 9 students at three metropolitan secondary schools participated. The study explored whether the presence of schemas, that facilitated greater problem-solving ability in gifted students, would generate clear evidence of instructional efficiency and preference for either mode of instruction. As students advanced from novice state to expert in particular domains of learning, it was anticipated that gifted students would progress from benefiting from worked example instruction to more efficient learning in guided discovery mode. This hypothesis was rejected as the results from each of the experiments did not confirm the hypothesised outcomes. There was no manifested expertise-reversal effect. The absence of any clear delineation of enhanced learning proficiency mode of instruction for gifted students does, however, contribute to the advancement and understanding of cognitive load theory and the complexity of learning strategies necessary for gifted learners
