Strategy is a way or method that is chosen or it can also be interpreted as a way to achieve a goal in education. The definition of a learning strategy can be interpreted as a plan that contains a series of activities designed to achieve certain educational goals. The learning strategy includes specific learning approaches, models, methods and techniques. This research is a qualitative method, which is a method that aims to make a systematic, factual, accurate description, picture or painting of the properties and relationships between the phenomena investigated. In other words, descriptive research takes the problem or focuses on actual problems as they were at the time the research was carried out. What was collected was in the form of primary data and secondary data about teacher strategies in online learning, the techniques used in data collection were observations, interviews and documentation studies. Research leads to the methods used by teachers in online learning activities using platforms such as WhatsApp, email, and technology-based zoom.

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 study aims to find out how to improve students' mathematical creative thinking skills after using the Problem Based Learning model assisted by Geogebra media and to find out how students' answers process in solving problems on the mathematical creative thinking ability test after applying the Problem Based Learning model assisted by Geogebra media. This type of research is Classroom Action Research (PTK) which was conducted in two cycles, the subjects in the study were class IX-3 MTs Citra Abdi Negoro, totaling 27 students. This research is said to be successful if it meets the indicators of success, namely, (1) The level of students' mathematical creative thinking ability increases with a value of ≥ 85% at least in the medium category, (2) The process of completing student answers with a value of ≥60% at least in the good category, (3) The results student and teacher observations show a good category. Based on the results of the study, the average initial ability test score of 58.10 increased to 61.34 in cycle I and 80.55 in cycle II. There was also an increase in classical completeness, in the creative thinking ability test of 8 students (29.63%) in the initial ability test increased to 12 students (44.44%) in cycle I and 25 students (92.59%) in cycle II. For the process of student answers from cycle I with an average presentation of 50 students' answer processes, 31% increased to 70.67% in cycle II. Based on the results of the study it can be concluded that the Problem Based Learning model assisted by Geogebra media can improve students' creative thinking skills.

The sample in this study was one class selected by cluster random sampling. Data collection techniques used are direct communication techniques and measurement techniques with data collection tools in the form of questionnaires and test questions in the form of essays. The data analysis technique used was the analysis of two dissimilar cell paths with the normality test using the Lilifors test, homogeneity using the Bartlett test and continued with the multiple comparison test using the Scheffe method. The results of this study are (1) the mathematical communication of students who follow the problem-based learning model is better than students who follow the conventional learning model, (2) the ability of mathematical communication between students who have high learning independence is better than moderate after the implementation of the model learning problem based learning. (3) students' mathematical communication skills in the moderate learning independence category were better than students in the low learning independence category after applying the problem-based learning model. (4) at the level of independent learning, problem-based learning models provide better mathematical communication skills than conventional learning models.

Based on observations made at SMA Negeri 1 Gunuang Omeh District, the problem found was the low interest in learning of students in PAI and BP subjects due to the large number of students who did not pay attention to the teacher's explanation, and the lack of use of learning models and media used in learning , one of which is the Problem Based Learning learning model. The role of the learning model is very important, because using visual media will be able to influence students' learning interests. The purpose of this study was to find out the use of the Problem Based Learning learning model in increasing students' learning interest in PAI and BP subjects on Da'wah Strategy and Islamic Development in Indonesia Class XII.MIPA at SMA Negeri 1 Gunuang Omeh District. This type of research is Classroom Action Research (PTK). The process of implementing PTK has four main components, namely planning, action, observation and reflection carried out in 3 cycles. The results of data analysis obtained the percentage of students' learning interest using the Problem Based Learning learning model of 44.83% in cycle I. The process of applying the Problem Based Learning learning model in PAI and BP learning increased in cycle II by 65.52% and 79.31 % in cycle III. So it can be concluded that the implementation of PAI and BP learning by using the Problem Based Learning learning model can increase students' learning interest.
