Item The development of critical thinking skills through the evaluation of internet materials(2017) Barnett, DavidThe internet supplies a continuous stream of information to our students. The information gleaned from the internet is ever-changing and scanty and researchers have used the term “paucity” to describe internet information. It is difficult to trust this information and value it as knowledge. The need for developing Critical Thinking and its application is advanced both internationally and in South Africa .This study, investigated the development of specific critical thinking skills for the purpose of evaluating internet materials for trustworthiness. Within this study a series of lessons were designed to develop Critical Thinking skills amongst a group of Grade 11 students at a private high school in South Africa. Once these skills were acquired the students were able to make a comparison between different internet materials and they made a well-reasoned argument about the credibility of these materials. The key skills were taught through the use of a Learning Management System (LMS). The LMS was used as a medium for isolating selected internet materials and to develop a pathway of learning. Several educational theories, models and philosophies were investigated as they were layered into the fabric of this research report. Critical thinking skills were developed through a blended approach. Although a LMS was used as a primary medium of the Critical Thinking process the teacher was the key agent for its facilitation. The research premise was based on deductive reasoning and presumed that it was necessary to use Critical Thinking to search internet material for trustworthiness. The design made use of a case study as the preferred method to investigate the premise. An inductive approach was then implemented to interpret the data obtained from the evaluation of internet materials. Pre and post tests and scales were instituted and a comparison was made of the students’ confidence and ability to evaluate internet materials using specific critical thinking skills. When comparisons were made of both qualitative and quantitative results there was evidence that there was an enhancement and effective application of the specific critical thinking skills brought about through this intervention.Item Investigating the relationship between attitudes towards tablet usage, access, learning styles, motivation and learner achievement in a blended learning environment(2016) Hart, SamanthaThe use of various information technologies in education is becoming more prevalent due to the fact that they are thought to have several advantages over traditional pen and paper as well as the fact that they are seen as a means to decrease the digital divide and ensure equal access to educational resources. In South Africa, initiatives such as the Smart Schools program aim to make schools paperless in the near future through the use of smartboards and tablets. With such emphasis on the success of the integration of educational technology it is imperative that we understand the factors which influence this process. Current research points to the idea that the mere provision of educational technology is not sufficient to garner success and that there are also intrinsic factors which need to be considered when integrating educational technology. This study follows on from this premise of intrinsic factors in that it investigates learner attitudes towards tablet usage in a blended learning environment. An extended version of the Technology Acceptance Model which posits that perceived usefulness, perceived ease of use and perceived enjoyability are the factors which need to be taken into account when exploring learner attitudes is used as the theoretical basis for this study. Other factors which are thought to influence attitudes as well as the success of tablet integration (as measured by learner achievement) are learning style preferences, motivation as well as access to various form of technology and thus familiarity with such technology. These factors were also explored through this research. Access to technology, learning style preference and motivation as predictors of overall attitudes and the three components of attitudes were thus explored. This study further investigated whether attitudes (and the three components of attitudes), learning style preferences or learner motivation best predicted academic achievement. The sample consisted of 276 learners from one independent and one public school in Johannesburg where tablets had already been introduced into the learning environment. A questionnaire consisting of an Attitudes Towards Tablet Usage Scale, a Learning Styles Scale, a Motivation Scale and an Access Scale was used. The results of this study indicated that overall attitudes towards tablet usage were relatively positive. The most positive component was perceived ease of use followed by perceived usefulness and then perceived enjoyability. Attitudes towards ECT (and the three components) were influenced by learning style preferences, motivation and access to technology while learner achievement was influenced by learner attitudes as well as learning style preferences. This provides valuable insights into the tablet integration process in that we conclude that tablet provision, while necessary, is not sufficient for the successful integration of tablets and subsequent reduction in the digital divide.
