That were managed to learn by using problems as a base 3) comparing critical thinking skills before and after studying Of Grade 9 students who were managed to learn using problems as an economics base 4) Student satisfaction questionnaire The statistics used for data analysis were hot value, mean, standard deviation. And t-test dependent statistics

        The research results were as follows: 1) The results of development of problem-based learning activities on the price mechanism in the economy To be effective according to the criteria 80/80 has 10 learning activity plans. Each plan contains standard essence / indicators / learning outcomes. Learning purpose Learning Learning activities Media / Learning Sources And measurement and evaluation The results of the evaluation of suitability were average from 4.14 - 4.48 and the results of the analysis for the effectiveness of the learning activities using problem-based problems were the price mechanisms in the economic system. To be effective (E1 / E2) = 88.33 / 82.22 which meet the specified criteria. 2) Grade 9 students who study with problem-based learning activities The GPA was 14.56 and the GPA was 24.66, with significantly higher post-study achievement at the .05 level. 3) Mathayom Suksa 3 students who study by organizing learning activities using critical thinking Having a pre-school GPA of 35.63 and a post-class mean score of 41.63, with a significantly higher post-study critical thinking ability than before at the .05 level. 4) Satisfaction of Grade 9 students with social studies subjects. (Citizenship, culture and lifestyle content) after organizing problem-based learning activities Has the highest level of satisfaction ( = 4.54, SD = 0.61)
