Students' performances in TIMSS have featured strongly in recent discussions and debates about the quality of mathematical learning outcomes both from teachers and policy makers. Findings of TIMSS trends showed that most high school students in Malaysia continue to perform at less than satisfactory levels, particularly, in tasks that are cognitively demanding. In this article, we present a critical analysis of selected TIMSS Tasks and demonstrate how to support students better in the use of Higher Order Thinking Skills (HOTS) in making progress with such tasks. In so doing we present analyses of TIMSS tasks and a model of these tasks that relate HOTS, representation and concepts which can be utilised by teachers to understand the role of HOTS better in empowering students shift to higher levels of cognitive funtioning in the context of tackling TIMSS and similarly demanding tasks. Our analyses and model provide an important starting point for the design of future professional development programs for Malaysian mathematics teachers in reconceptualising HOTS and implementing them in regular classrooms.Key Words: thinking skills, problem solving, mathematics, TIMSS Tasks, teacher, level of cognition, representation
INTRODUCTIONStudents' mathematics achievement is often associated with the future economic power and competitiveness of a country. Therefore, the desire to understand and identify factors that may have meaningful and consistent relationships with mathematics achievement has been shared among national policy makers and educators around the world. Today, it is widely accepted that the main purpose of educational systems is to teach students how to apply mathematics in a range of contexts. Higher Order Thinking Skills [HOTS], such as logical thinking, critical thinking and reasoning skills are the basic skills for daily life, apart from the academic achievements in the schools (Marshall & Horton, 2011). In order to increase the performance of students, the nature and The extent to which mathematics teachers understand the role of HOTS in learning and applying mathematics is emerging to be an issue. Hinde and Perry (2007) commented that teacher in general tended to associate cognitive skills with the school's curriculum, with limited attention to the role of these skills in facilitating students' thinking and learning within particular subject. Further, teachers have limited opportunities to engage in activities with the students that will support the development of high order cognitive abilities (Ewing, Foster & Whittington, 2011). The ability to integrate HOTS in mathematics can be hampered by a number of factors including teacher's limited knowledge of HOTS (Brookhart, 2010;Collins, 2014;Harpster, 1999).Trends in International Mathematics and Science Study [TIMSS] and Programme of International Student Assessment [PISA] are two large-scale international comparative achievement studies that assess students' performances in mathematics. The pattern of results in TIMSS and PISA has revealed a marked declin...
