摘要：The purpose of this research is to describe student productive thinking in solving problem in algebra. The subject of this research is choosing four subjects which have different productive thinking. The first instrument is using self-regulated learning questionnaire,then the second instrument is giving a test and interviews. The result indicated that student with high self-regulated learning,thinks really critically,and his creativity has the ability of thinking productive. Students which have the ability to think productively have the following characteristics:they are able to identify problem well,they are able to write facts clearly and they are able to describe what is already known and what has been questioned in the question precisely,right in writing the mathematics model,and they are also able to make calculation and check the rightness which happen as well. They give more than one relevant idea and find more various ways dealing with the problems,give the answer in detail,clear and complex,make right conclusion and doing calculation precisely,double check their answers by using the known matter in the problem.
