Technology in education demands innovative and creative learning by utilizing android smartphones to improve student learning outcomes. Therefore, this study aims to develop and produce an android-based application on algebraic form material to improve student learning outcomes for grade VII students of SMP Negeri 8 Kupang that is valid, practical, and effective and to find out teacher and student responses to the application.The method used in this study is the Research and Development (R&D) research method and the model used for ADDIE development which consists of 5 stages, namely analysis, design, development, implementation andevaluation (evaluation). Data collection techniques used are interviews, questionnaires and learning outcomes tests. The data analysis technique used is qualitative data analysis and quantitative data analysis.The results showed that the Algebra Learning Application met the valid, practical and effective eligibility criteria and was able to improve student learning outcomes. The average total validity by material experts is 4.01, education practitioners are 4.23, and media experts are 4.66, with the "valid" category. The average total practicality of the teacher is 4.81 and that of the students in the small group is 4.2, while in the large group is 4.62 with the "practical" category. The percentage of mastery learning using learning media is 83.33% in the "effective" category. There was an increase in interest and completeness of student learning outcomes which initially increased from 40% to 83.33% so that the Algebra Learning application was very feasible to use.

Mathematics learning in this era requires teachers to be able to develop learning models that pay attention to the characteristics of students, so it is important for teachers to know learning trajectory. This study aims to describe the conception of learning trajectory and hypothetical learning trajectory, as well as presenting the design of hypothetical learning trajectories in mathematics learning. Based on the theories studied, it is concluded that hypothetical learning trajectory is a learning design in the form of allegations on student learning activities based on initial understanding and characteristics of students to achieve higher understanding. HLT has three main components namely learning objectives, learning activities, and hypotheses of the learning process. HLT is used by teachers as a guide to predict and prepare learning flow designs that are appropriate to the stages of student thinking and can improve student learning outcomes. The findings of previous studies show that to design HLT in mathematics learning, educators need to consider student obstacle learning, a hierarchy of material, and learning support capacity, so that learning activities to be hypothesized are built based on these things. It is recommended that future researchers can use the existing HLT, and also develop HLT in other materials that have not been tested by further studying HLT and whatever affects it, research with different differences can be used.

Topik fungsi kuadrat dimulai dari menggambar grafik, menganalisis bentuk grafik serta penentuan sumbu simetri dan nilai optimum. Ketiga materi ini dalam praktiknya memiliki masalah terkait pemahaman dan motivasi siswa. Penelitian ini bertujuan menerapkan pendekatan saintifik dengan GeoGebra untuk meningkatkan motivasi dan hasil belajar siswa. Jenis penelitian adalah penelitian tindakan kelas, dengan subjek penelitian sebanyak 32 siswa pada kelas IX C SMPN 5 Kupang. Instrumen penelitian yang digunakan yakni soal tes hasil belajar tiap siklus, dan lembar observasi motivasi siswa. Analisis data menggunakan statistik deskriptif. Indikator keberhasilan dalam penelitian ini adalah jika secara individu siswa telah mencapai nilai KKM 70 dan secara klasikal 75% siswa mencapai nilai KKM tersebut. Hasil penelitian menunjukkan pada siklus I, 73,73% siswa memiliki motivasi yang baik dalam mengikuti pembelajaran dan meningkat menjadi 80,93% pada siklus II. Lebih lanjut, hasil belajar pada siklus I dikategorikan memenuhi indikator ketuntasan karena lebih dari 70% siswa tuntas secara klasikal. Presentasi ini meningkat menjadi 78,125% pada siklus II. Peningkatan ini menunjukan penerapan pendekatan saintifik dengan media GeoGebra memberi dampak yang postif terhadap hasil belajar siswa. Berdasarkan hasil penelitian, peneliti merekomendasikan kegiatan pembelajaran dengan pendekatan saintifik dengan GeoGebra dapat diterapkan dalam pembelajaran fungsi kuadrat

This review aims to describe the model, characteristics, and design of blended learning, to describe the trend of research blended learning in supporting the development of students' mathematical thinking skills and to provide recommendations for blended learning in supporting the development of students' mathematical thinking skills in the future. The method used in this paper is an article review method which is carried out in three stages, namely identifying keywords related to blended learning in developing mathematical thinking skills, article search strategies, and analyzing articles. Blended learning is a combination of learning patterns, between face-to-face learning and online learning. The trend of Blended learning is carried out with online learning and face-to-face learning in class is carried out alternately (rotational model), using various LMS. The results of the article analysis show that the blended learning stage can develop students' mathematical thinking skills, namely the seeking of information stage students are directed to think critically. At this stage students are more motivated and independent in finding or accessing materials online. Then at the stage of acquisition of information and synthesizing of knowledge, students are directed to solve problems, use mathematical understanding skills, reasoning, connection and representation skills, communication and collaboration, and think critically through discussions, presentations, and work on practice questions. In addition, students look more enthusiastic and motivated because it is adjusted to their learning style and learning speed and students are directed to be independent in learning the material. The researcher recommends a blended learning design using the flipped classroom model with online learning using the Moodle LMS in which each stage of blended learning, students are directed to rely on mathematical thinking skills. Keywords : Blended learning and mathematical thinking skills

This study aims to develop online learning tools in the Algebra Structure course. This research is a development using the Kemp model. The learning tools produced in this study are RPS, RTS, teaching materials, learning videos and learning outcomes tests. The results of the validation and testing of the learning tools show that learning tools are valid, practical and effective. The average validator's assessment of the RPS, RTS, Teaching Materials, Learning Videos and Tests Learning outcomes are 3.72, 3.76, 3.76, and 3.72 with good criteria. The average value of observations by observer 1, observer 2 and observer 3 is 4.00, 4.06, and 4.12, with good categories. The results of student responses showed that 93.482% of students satisfied with the teaching component, 84.09% of students satisfied with the novelty of the learning component, 94.87% interest in participating in further learning, 88.88% expressed satisfaction with language clarity, 91.42% satisfied with the appearance of the material teaching and learning videos. The validation of the questions showed that there were 3 items with high validity, and there were 6 items with sufficient validity. Furthermore, the test reliability coefficient = 0.79 which indicates that the learning outcomes test has high reliability and is used without revision. Thus, the validation and testing of the device shows that student activities are effective, lecturers' ability to manage learning is good, student responses are positive and test results are valid and reliable.
