Developing Ability to Problem Solving about Kirchoff’s Law by Blended Learning Model Using Problem-based Learning and Peer-assisted Learning Technique for 1st Year Higher Vocational Certificate

The purposes of this study were (1) To design and study the quality of integrated teaching and learning using problem-based and thinking partner techniques. To promote problem-solving ability (2) To measure the problem-solving ability of the sample group after learning with integrated teaching using problem-based and thinking partner techniques (3) To compare Academic achievement on Kirchoff’s law of the sample between before and after class (4) To study student satisfaction with integrated teaching and learning activities using problem-based and thinking partner techniques. Conducting research by collecting data from 1st year Higher Vocational Certificate students at Phichai Vocational College Who were enrolled in the course Electrical Circuits 1 in semester 1 at academic year 2023. The tools used in the research were 1) A lesson plan for the Electrical Circuits 1 course on Kirchoff’s law 2) Activities to practice problem solving ability 3) Academic achievement exercises 4) Experimental worksheets 5) Satisfaction measurement forms Statistics used include percentage, mean, and standard deviation. and t-test (t-test). The research results include: (1) Integrated teaching and learning activities using problem-based and thinking partner techniques it promoted the ability to solve problems The quality is at a very good level. (2) Integrated teaching and learning activities using problem-based and thinking partner techniques. It promoted the ability to solve problems 85.2%. Students had problemsolving skills at a better level. (3) Integrated teaching and learning activities using problem-based and thinking partner techniques had significantly higher achievement scores than before studying at the 0.05 level and (4) Students are satisfied with the blended teaching and learning activities using problem-based learning and thinking partner techniques at a high level.
