Discovery learning is a learning that involves students in the process of mental activity through a brainstorm, to discuss, and try it yourself, so that children can learn to be independent. Resulting in the discovery-based learning problem solving is to let children discover things on their own and group investigation that emphasizes problem solving based on a debriefing activities and student participation. The classes drawn into the sample, the class as a class given control based discovery learning and problem solving one class another group investigation given learning-based problem solving. Data analysis techniques in this study using Ttes. From the results of this study concluded that: (a) In the first experiment class that implements learning model-based problem solving group investigation obtained average value of learning outcomes at 73.10 while the experimental class II implementing discovery-based learning problem solving obtained average value postest average of 66.55. (b) There are significant differences between the results of student learning in the class that implements the discovery-based learning and problem solving class that implements the learning model based problem solving group investigation.

<p class="AbstractEnglish"><strong>Abstract:</strong> This study aims to determine the interaction/influence of the application of the project based Double Loop Problem Solving learning model in improving Critical Thinking Skill and student Interpersonal Skill. This research is in the form of quantitative research and the sample used in this study is one class taken using Saturated Sampling techniques. The research class was treated using a project-based Double Loop Problem Solving learning model. The independent variable in this study is a project based Double Loop Problem Solving learning model, while the dependent variable is Critical Thinking Skill and student Interpersonal Skill. There are 2 kinds of data analysis techniques, namely data analysis techniques about Critical Thinking Skills and data analysis techniques about student Interpersonal Skills. The analysis of the hypothesis test of this study used the T-Test with a significance level of 5%. T-Test Criteria are as follows, Ho is accepted / H1 is rejected if T count is smaller than T table and Ho is rejected / H1 is accepted if T count is greater than T table. From the results of the TT-test for the first dependent variable Critical Thinking Skill T count = 18.77 and T table = 1.782, because T count is greater than T table, Ho1 is rejected, meaning that there is interaction/influence on the implementation of project based Double Loop Problem Solving learning model in improving Critical Thinking Skill. While the results of the T test for the Interpersonal Skill dependent variable obtained T count = 12.33 with T table = 1.782, because T count is greater than T table, Ho2 is rejected, meaning that there is interaction / influence on the application of Double Loop Problem Solving based learning models to improve Student Interpersonal Skills.</p><p class="AbstractEnglish"><strong>Abstrak:</strong> Penelitian ini bertujuan untuk mengetahui interaksi/pengaruh penerapan model pembelajaran <em>Double Loop Problem Solving </em>berbasis<em> project</em> dalam meningkatkan <em>Critical Thinking Skill</em> dan <em>Interpersonal Skill</em> mahasiswa.

This research intends to study the conditions and problems of learning management in Mathematics for undergraduate students. The research problem is that students have low achievement and ability problem-solving in mathematics. The research method used is development through conducting preliminary studies and quantitative survey research, producing initial designs of integrative learning models. The results of this research were used to develop the mathematics learning model. The research was conducted over one year considering two groups. The first sample was collected from the group with 376 students studying mathematics in the academic year 2020. The second sample was collected from the group with 116 professors of public universities in Thailand. Questionnaires were used as a tool of the research. The data analysis was divided into two stages. The first stage was to analyze supporting factors with factor analysis. The second stage was to design the learning management of students and professors with regression analysis. The results have shown that the opinions of students and professors on conditions and problems of learning management can be summarized as follows: (1) The students’ arguments for corrections in the aspects were group learning and teamwork, steps of solving problems, a learning model that is real situations, and the problem-based learning, respectively. (2) The professors’ opinions for corrections in the aspects were student interaction, academic achievement, problem-based learning, and learning management model that is current situations, respectively. (3)The supporting factors for developing the learning management model that professors and students were consistent in solving problems. It was found that there were three main factors as follows; group learning, problem-based learning, and active learning. The learning management model should be developed by integrating group learning, problem-based learning, and mathematical problem-solving to enhance problem-solving and mathematics learning achievement.
