The TI-Nspire CX is a mobile device developed by Texas Instrument that can be used in the mathematics classroom. A learning environment based on this mobile device was designed to help secondary school students to enhance their higher order thinking. In a traditional mathematics classroom, students have difficulties developing their higher order thinking. Through the TI-Nspire-based learning environment, students will get to develop a greater understanding of the mathematical concepts and ideas and enhance their creative thinking, critical thinking and mathematical thinking abilities such as mathematical problem solving, reasoning, communication, connection and representation. In the TI-Nspire-based learning environment, students will be provided with tasks that requires students to perform mathematical exploration, investigation, problem solving and modelling. The tasks will provide students with opportunities to use mathematical tools systematically in solving problems and be engaged in investigation and exploration of patterns and relationship to help them enhance their reasoning abilities and communication skills. The tasks will require students to model real world situations mathematically so that they can develop an understanding of the world through the model and of how the model can be used to make further prediction if changes were to occur to this situation. The TI-Nspire, as a mobile and inexpensive device can be of great help in reducing the challenge of developing and enhancing higher order thinking of students in the secondary mathematics classroom.
