The Effectiveness Of Mathematical Learning Tools Based On Thinking Aloud Pair Problem Solving (Tapps) Towards The Problem Solving Ability Of Grade X High School Students

The purpose of this research is to know the effectiveness of mathematical learning tools based on Thinking Aloud Pair Problem Solving (TAPPS) towards the problem solving ability of grade X high school students.TAPPS's technique is applied by using student's worksheet.The trial is done on 32 grade X students at SMAN 1 Batang Anai.The testing of effectiveness is refers to provision in quasi experiment.The design model is Posttest-Only Control.The conclusion of this study is the student's problem solving ability that use mathematical learning devices based on Thinking Aloud Pair Problem Solving (TAPPS) are higher than the student's problem solving ability without TAPPS of Trigonometry lesson.
