Abstract

Kajian ini dijalankan untuk menentukan dan mengatasi masalah melakar graf fungsi eksponen dan logaritma. Tinjauan awal dilaksanakan melalui pemerhatian hasil kerja pelajar dalam latihan/tugasan tutorial, kuiz, ujian pra dan temubual menunjukkan pelajar tidak dapat melakar graf fungsi eksponen dan logaritma dengan tepat dan lengkap. Pelajar langsung tidak tahu/faham langkah kerja yang perlu dicari sebelum melakarkan graf fungsi eksponen dan logaritma, serta keliru dengan bentuk graf fungsi tersebut. Perancangan tindakan difokuskan kepada teknik ‘DAIS’ untuk meningkatkan kefahaman dan kemahiran pelajar bagi melakarkan graf fungsi eksponen dan logaritma. Keputusan ujian pos telah menunjukkan peningkatan prestasi pelajar. Dapatan temubual pula menunjukkan pelajar lebih memahami dan seronok belajar melakar graf fungsi eksponen dan logaritma melalui teknik ‘DAIS’.

The aims of the study is to determine and overcome problems associated with sketching exponential function and logarithm graphs. Surveys on student works (assignment, quiz and test) and interviews showed that students were unable to sketch correctly and acurately exponential function and logarithm graphs because of the lack of understanding on the procedural works that they must undertake before sketching the graphs. A learning method called 'DAIS' was employed to help student to overcome the problems. 'DAIS' is an acronym for D=Domain, A=Asymtote, I=Intercepts and S=Sign. Post test results show that there is an increase in the performance of the student's skills after using the 'DAIS' technique.
