Learning implementation based on five mathematics teaching practices to enhance problem posing and problem solving on probability of Mathayomsuksa 3 students
Main Article Content
Abstract
This research aimed to 1) study appropriate learning implementation based on five mathematics teaching practices to enhance problem-posing and problem-solving abilities and 2) study the effects of learning implementation based on five mathematics teaching practices on problem-posing and problem-solving abilities in the topic of probability of Mathayomsuksa 3 students. The participants were 20 students in a secondary school in Nakhon Sawan Province. The researcher applied classroom action research for 3 cycles with a total duration of 12 hours. The research tools were lesson plans, reflection form, activity sheets, problem posing and problem solving notes and a test for problem posing and problem solving. The data were analyzed by content analysis and analytic scoring. The results showed that the appropriate learning implementation based on five mathematics teaching practices to enhance problem posing and problem solving should emphasized some points. Firstly, teachers should choose mathematical tasks or situations that engage students' interest. They might help student to discuss in class and get idea for problem posing. Secondly, teachers should select and order students' work to present in the order from less understanding to complete understanding in probability. This will help students learn from mistakes until they build knowledge on their own. Finally, the teacher should initiate a discussion by giving an example and using open-ended questions. This will help students to inquiry and discuss with their classmates. Most students are in a very good level of problem posing and problem solving ability, that is, they are able to set up a situation or problem related probability with appropriate information, conditions, and questions. Then they can understand the problem, choose a solution strategy, implement appropriate strategies for problems solving, and make a conclusion of problem and concepts of probability.
