Research study on sixth grade problem-posing instruction: Case of addition, subtraction and number comparison on decimals
Abstract
The aim of this research project is to investigate the implementation of problem-posing instruction on decimals to one sixth-grade mathematics class. There are four research objectives: 1) design and implement problem-posing instruction on decimals; 2) discuss the status of children¡¦s performance in problem-solving; 3) analyze the type of problems posed by children; and, 4) display categories of misconceptions exhibited when children did problem posing. The stages for instructions were three: 1) children solved the problem given by the instructor; 2) children referred to given problem and posed a problem; and, 3) children solved their own problem. In this study, the type of problem posing chosen for instruction is ¡§similar problem¡¨, which is adapted from Tsubota, a Japan scholar. The researcher collected data by using: own constructed decimal problems question sheet, worksheet on problem solving, worksheet on problem posing, children¡¦s diaries and teachers¡¦ notes on instruction.
There are four findings. First, the implementation of sixth grade problem-posing instruction on decimals is feasible. Second, 96.9% of students¡¦ problems are plausible and contain sufficient information for problem solvers. Most students could change the number and content of the question but few revised the structure of the question. There was also multiple development for those problems. Third, children¡¦s performance in posing/solving stage was better than that in problem-solving stage.
Finally, the researcher reported that the teacher faced problems such as difficulty in control of time, establishing children¡¦s habit in reporting, and collecting misconceptions of children.
