Science and Mathematics Education Centre Cognitive Acceleration in Mathematics Education in Tonga: Effects on students’ mathematics achievement, motivation, and self- regulation Teukava Finau This thesis is presented for the degree of Doctor of Philosophy of Curtin University May 2017 i Abstract There are three major issues experienced by many secondary schools in Tonga, namely, the increasingly poor performance of students in mathematics, the low level of students’ engagement in mathematics, and the increasing number of students who enter high schools with insufficient skills in mathematics. The current mathematics curriculum and teachers’ teaching skills do not have the capacity to provide an effective learning environment so that students could improve their reasoning skills and mathematical understanding. Therefore, there is an urgent need for innovative teaching and learning approaches that have the potential to contribute to solving these issues in secondary schools in Tonga. The Cognitive Acceleration in Mathematics Education (CAME) program is an innovative teaching approach based largely on Piaget’s cognitive development theory and the socio-cultural psychology of Vygotsky. The CAME program involves the application of some special learning and teaching procedures in mathematics classes which results in students attaining higher levels of cognitive development more quickly than if they had not been presented with these procedures. The materials for the CAME program were adapted and implemented in Tonga over the course of one school year (March – November) with the main purpose of the research to investigate the effects of the CAME program on Tongan Form 2 (Year 8) mathematics students’ achievement, learning motivation and self-regulation, and the teachers’ teaching practices. A quasi-experimental with non-equivalent comparison groups design was used to provide responses to the research questions. The researcher developed two instruments - Numeracy Reasoning Task 1 (NRT1) and Numeracy Reasoning Task 2 (NRT2) – with 20 items each which were administered to 338 students in the experimental and the comparison groups as a pre-test (NRT1) and post-test (NRT2) to explore the effects of the CAME program on students’ achievement. The experimental group post-test performance was significantly higher than the post-test performance of the comparison group students, suggesting the positive impact of the CAME program in the Tongan Form 2 mathematics students. The results of independent t-tests analysis between the iii experimental group and the comparison group students’ performance as well as the results of the paired sample t-test analysis between the NRT1 pre-test and the NRT2 post-test in each group indicated that the CAME program was more effective with regards to students’ understanding and achievement compared to the traditional instruction in Tonga Form 2 mathematics topics. The adapted Students’ Adaptive Learning Engagement (SALE) instrument was administered to 338 students in the experimental and comparison groups as a pre-test and post-test to investigate the effects of the CAME program on students’ learning motivation and self-regulation. The independent t-test analysis results between the means scores of the experimental and comparison groups showed that there were statistically significant differences in all the four scales of the SALE instrument with students in the experimental group having higher mean scores than the comparison group. The results suggest that the CAME program was effective in improving the Tongan Form 2 students’ learning motivation and self-regulated learning. The analysis of the teachers’ interviews revealed that the CAME program had positive effects on the experimental teachers’ teaching pedagogies and the teachers’ behaviours when they interacted with their students. This study has made a distinctive contribution to the Tonga Form 2 mathematics curriculum and mathematics teachers’ teaching pedagogy, being the first study in Tonga to investigate an approach that promotes the development of mathematical thinking skills to improve students’ achievement and learning motivation and self- regulation. The study revealed that teaching higher order thinking is appropriate and possible for the Tongan students no matter what levels of thinking ability they have. Also, this study showed that a specially designed professional development program could contribute to improving the teachers’ teaching practices which became more student-centred in terms of how they communicate and interact with the students. Although the CAME intervention was the focus on the Tonga mathematics Form 2 level, the teaching strategies and theories could be applied to the teaching and learning of other class levels, subjects, and the primary school students in Tonga. iv Acknowledgements It is my opinion that no single person completes a doctoral thesis all on his or her own. Definitely, it takes self-initiative and motivation to complete a task such as this, but a person is by nature a social being and thereby requires people with whom to interact and work in order to be able to reach the completion of a doctoral degree. I have been blessed with many different people and groups in my professional and personal life that have helped to guide, direct, steer, and love me along the way. I am very grateful for the support, encouragement, and guidance of the people at Curtin University, especially in the STEM research group. I wish to express my sincere gratitude to my supervisor, Professor David Treagust who has guided me throughout my research in the CAME program research project. I will be forever indebted to him for all the exceptional guidance, prompt feedback and response. I also wish to thank to my other supervisor, Senior Lecturer Dr Mihye Won for her intellectual contributions and guidance that enriched my research work. I extended my sincere thanks to Dr. Arulsingam Chandrasegaran, my data expert, who took on the task of helping analyse my data. Without you, Dr. Chandrasegaran, I would never have completed the quantitative data analysis. My sincere gratitude goes to the Australia Government (AusAid) for the financial support towards my study without which this work would not have been possible. I also would like to extend my sincere thanks to the Pearson Education Limited and Copyright in the UK for the permission to use in my study the materials in their published book known as Thinking Maths. I appreciate this support and help which enable this study to be completed. I am greatly indebted to my family, to my mother, Ana Paongo Finau for her support and encouragement from home (Tonga). I would also like to express my thanks to my siblings, my in-laws as well as the Tongan relatives in Perth for their support for my family in many ways. Lastly, I would like to thank my wife, Ana Siale Finau, and my son, Teukava Finau Jr, for accompanying me here in Australia during my study, and especially for my wife, who undauntedly endured several late hours of my work with v subsequent neglect of family duties. All things considered, without her persistent support this thesis would never have been finished. vi Dedication I dedicate this doctoral thesis to my parents, Vainima Finau and Ana Paongo Finau; to my wife, Ana Siale Finau; to my son, Teukava Finau Jr, and to my high school science and mathematics teacher, Kilupi Tukutukunga, who inspired me to become a special mathematics and science teacher. vii Table of Contents Declaration .................................................................................................................. ii Abstract ...................................................................................................................... iii Acknowledgements ..................................................................................................... v Dedication ................................................................................................................. vii Table of Contents ..................................................................................................... viii List of Figures ............................................................................................................ xi List of Tables............................................................................................................. xii Chapter 1 Introduction ......................................................................................... 1 1.1 The research problem .................................................................................... 1 1.2 Related research ............................................................................................ 2 1.3 Background of the study ............................................................................... 3 1.4 Rationale for the study .................................................................................. 5 1.5 Research Aims and Research Questions ....................................................... 6 1.6 Research Methodology ................................................................................. 7 Research Design ....................................................................................... 8 Sample selection ....................................................................................... 8 Data Sources ............................................................................................. 8 Data Analyses ........................................................................................
