Abstract

The problem is that there is disequilibrium between old knowledge and new knowledge which makes mathematics education students difficult to study material on systems of linear equations in elementary linear algebra courses. Therefore, they need media that can facilitate old knowledge and new knowledge so that knowledge is equilibrium. One of the media that can be used is the advanced organizer student worksheet. The aim of this research is to produce an advance organizer model student worksheet that is valid, practical and effective. This research is development research using the ADDIE model (analysis, design, development, implementation and evaluation). At the analysis stage, needs analysis, material analysis and learning environment analysis are carried out. At the design stage, an LKM is created which has four characteristics, namely identity, presentation of an advance organizer, presentation of the main material and practice questions to strengthen the schema or cognitive structure. Then at the development stage, the LKM that has been designed is validated by experts. Then at the implementation stage, small trials are carried out to get practical LKM and large class trials to get effective LKM. Then the evaluation stage concerns the things that need to be evaluated in the LKM. After going through this research stage, the results were conclude that 87.72% valid, 94.84% practical and 59% effective for student learning outcomes.

Abstract

Every concept in mathematics is related to one another. In addition, a concept can be a prerequisite for another concept. One concept in mathematics is the Pythagorean Theorem. In line with the results of interviews with mathematics teachers at SMPN Tublopo where there are still many students who do not understand the Pythagorean Theorem material and many students are still not focused and do not pay attention to the teacher during the learning process. So a solution is needed to solve the problems being experienced, one of which can be done is to do community service by implementing the Pythagorean puzzle media. Community service activities really help students understand the Pythagorean theorem material with the help of Pythagorean puzzle teaching aids. Based on the results of the pre-test and post-test, it can be seen that there was an increase of 270.83%. And based on the questionnaire, it can be seen that students find it easier to answer math questions, are happier and more enthusiastic when learning uses puzzle media. Students also find it easier to solve problems related to the Pythagorean theorem because of the help of puzzle media. Overall, we can see that there was a positive response from students after this community service was carried out based on the results of the questionnaire given after the activity ended.

Abstract

Artificial Intelligence chatbots have become famous nowadays because of their ease of use, which is even felt by educators and students. However, the AI chatbot algorithm sometimes does not match what is expected because it is not precise and does not match the prompt. For example, when we type the prompt "basic concepts of mathematical modeling for middle school class VII" there is very little explanation of the basic concepts. The search results provided by AI chatbots are too complex for students who want to learn simple basics. Based on this, this research was carried out with the aim of developing an AI chatbot to support differentiation learning. This type of research is ADDIE model development research which is carried out in five stages, namely analysis, design, development, implementation and evaluation. The results of the research at the analysis stage are that students need learning media that is appropriate to their level of understanding of mathematical modeling material as basic material before studying other material. The results of this analysis are the basis for designing an AI chatbot and bot scenarios to be developed and given to experts, namely educational technologists and mathematics education lecturers. After that, small class trials and large class trials at the implementation stage to get practicality and effectiveness test results in using the AI chatbot. The final stage is evaluation as a process of reflection on the results of AI chatbot development. The research results show that the AI chatbot media developed is valid, practical and effective. Valid criteria with a percentage of 89.7%, practical criteria of 85% and effective criteria of 77.67% in small group trials.      Keywords: chatbot AI, differentiated, mathematics learning.
