In the process of learning to write, students have the potential, interests and needs to be developed by the teacher. Therefore, the teacher has an important role in the language learning process, especially in the aspect of writing skills. The facts that occur in the field from the results of the author's observations in class X AKL 3 SMK N 6 Medan, the Indonesian language learning process is still not good enough compared to the mandatory learning process contained in the 2013 curriculum. And student learning outcomes in Indonesian, especially in the basic competence of writing negotiating texts, are still low. Therefore, to improve students' ability to write negotiating texts, learning models and media are needed so that students are able to write negotiating texts easily and pleasantly. The models and media used to overcome this are the use of project-based learning models and audio-visual media. With the use of this model and media it is expected that students will find it easy to write negotiating texts, because with these models and media students compose a negotiating text based on their direct experience. The background of the problems above is to implement the use of project based learning learning models and audio-visual media as an effort to improve students' ability to write negotiating texts in class X AKL 3 SMK N 6 Medan. Based on the results of research conducted in cycle I and cycle II in learning to write negotiating text using project based learning media and audio visual media, it was found that there was an increase in write negotiating text. This can be seen from the average value in the first cycle which was 64.78 and increased in the second cycle which was 80.03.

This study identified the challenges faced by students in writing persuasive texts, as well as exploring the potential for implementing PBL to improve writing skills. This research was conducted using the classroom action research method in class VIII SMP Negeri 11 Medan in the 2022/2023 academic year with a total of 32 students. Actions taken by applying the Problem-Based Learning learning model. This research was conducted in two cycles. Based on the results of research on student activity, it was found that the average value of student activity at the first meeting was 65.15%, at the second meeting, the percentage of activity value was 77.07%. The average value of student activity at meeting III was 70.09%, including the active category. Meanwhile, at the fourth meeting, the percentage of activity values ​​was 72.66% and if it was included in the criteria for student activity, this student activity was included in the active category. Overall, if an average of each cycle is obtained, the results of persuasive text writing skills have increased from 71.61% (active enough category) in cycle I to 71.37% (active category) in cycle II, which means an increase of 9. 76 %. Thus it can be seen that the Problem Based Learning learning model can improve the skills of writing persuasive texts and students understand learning material more easily.

A This study aims to determine: (1) the effect of Blended Learning models towards Mathematical Student’s Problem Solving Abilities and Self-Regulated, (2) the improvement of student’s mathematical problem solving and self regulated learning (3) the advantages of the advantages and disadvantages of blended learning model. This type of research includes descriptive qualitative research using library research methods. The data in this study were obtained from a collection of literature such as theses and journals that are relevant to the topic of discussion, namely Mathematical Student’s Problem Solving Abilities And Self-Regulated. The results show that, 1) Blended Learning Model has a great effect on students' problem solving abilities based on the overall effect size calculation which produces an average effect size of 1.56 where this number is included in the high category and Blended Learning Model has a great effect on student’s self-regulated based on the overall effect size calculation which produces an average effect size of 1.73  2) There is an increase in  mathematical the student's problem solving abilities and self-regulated learning that are taught through blended learning models. This can be seen from the achievement of N-Gain value and indicators in the experimental class in the literature which is generally better than the control class. 3) Based on the analysis, it was found that the advantages and disadvantages of blended learning. it can be obtained that the advantages of blended learning models as follows: (a) Learning is more effective and efficient, (b) Improve accessibility. with blended learning, it is easier for learning participants to access material learning. and disadvantages of blended learning is Not evenly distributed facilities owned by students, such as computers and internet access. Even though blended learning requires adequate internet access, if the network is inadequate it will make it difficult for participants to take part in independent learning via online.

This research is a Classroom Action Research (PTK) consisting of 2 cycles, each consisting of 2 meetings. Before giving action, an initial ability test is first given and at the end of each cycle is given a problem-solving ability test. From the results of the analysis of initial ability test data, it was obtained that many students achieved learning completeness from the initial ability test, namely 18 out of 28 students or 21% with a grade average of 26,7. The results of data analysis in the first cycle after applying the Reciprocal Teaching type cooperative learning model showed that the number of students who achieved learning completeness was 13 out of 28 students or 61% with a grade average of 70,7. The results of data analysis at the end of cycle II with the same learning obtained the number of students achieving learning completeness, namely 24 out of 28 students or 86% with a grade average of 90,86. This means that there is an increase in students' mathematical problem-solving skills from cycle I to cycle II. Based on classical completeness criteria, this learning has reached the classical completeness target.

This article discusses the teacher's perception of Problem Based Learning to improve students' thinking skills. Critical thinking is something that every individual has in developing abilities. This model can be applied to increase student excellence in thinking to find a way out of a problem through direct experience and student knowledge. Problem Based Learning is a learning model that is given based on problems, where students are given a problem and asked to solve the problem critically. Researchers use descriptive qualitative because the information collected is in the form of verbal. Samples were taken from fifth grade elementary school teachers. This study states that students' ability to think in grade V elementary school increases by implementing PBL-based learning. Before using the PBL model in class V students, learning was too monotonous, lack of enthusiasm and passivity, and students also had difficulty understanding the material, less sharp dexterity of opinion, students' excess in thinking was less developed and less flexible. However, after using the PBL learning model, students' ability to think in class V is increasing in solving problems, students also become more responsive to the essence of the problem, students also become creative, active and critical and are increasingly able to find solutions to a problem, as well as students' thinking skills. growing and flexible.

This study aims to determine the use of audio-visual media in Problem-Based Learning to improve student learning outcomes in tenth grade SMA Negeri 2 Tondano using classroom action research as the research methodology. (1) Planning, (2) Action, (3) Observation, and (4) Reflection are the four major phases of a cycle. In data analysis, the1percentage of completed student1learning outcomes is utilized. The research result was derived from student learning outcomes using two cycles; in cycle I, the1percentage of classical completion was 44.44 percent and in cycle II, it was 55.55 percent. It became a reference for the subsequent cycle's follow-up. The classical percentage of completeness for cycle II was then 92.59 percent complete and 7.40 percent incomplete. This demonstrated that it followed the research indicator in a conventional manner. Therefore, it is unnecessary to follow the subsequent cycle. This study concludes that using problem-based learning audio-visual as a learning medium for virus materials is crucial for improving student learning outcomes among students in1class X at SMA Negeri 21Tondano.
