Pandemic Covid-19 membawa dampak yang cukup signifikan terhadap proses belajar mengajar. Didasari perubahan cara belajar secara luring menjadi daring baik pada mata kuliah teori maupun praktik, tentu perlu mendapatkan perhatian khusus dalam proses penyampaian materi perkuliahan. Oleh karena itu perlu adanya pengembangan media khusus yang dapat dipelajari oleh mahasiswa secara mandiri. Penelitian ini bertujuan merancang, mengimplementasikan, mengetahui kelayakan media, kepraktisan media dan keefektivan media serta respon mahasiswa terhadap pengembangan media video tutorial pada mata kuliah teknologi menjahit untuk materi cara mengoperasikan mesin jahit. Video ini dikembangkan guna mendukung pembelajaran daring dimasa pandemic virus corona. Pengembangan media video tutorial menggunakan model pengembangan 4-D melalui 4 tahapan yaitu tahap Define (pendefinisian), tahap Design (perancangan), tahap Development (pengembangan) dan tahap Disseminate (menyebarkan). Penelitian dan pengembangan ini melalui tahap uji validitas, uji praktikalitas dan uji efektifitas. Hasil penelitian terhadap uji validitas oleh ahli materi dan ahli media dengan skor 3.75 pada rerata 3.20 – 4.00, maka aspek yang dinilai dikategorikan sangan jelas atau “Sangat valid”.  uji praktikalitas sebesar 89.1 % dengan kategori “Sangat praktis”. dan uji efektifitas pada faktor motivasi balejar mahasiswa sebesar 85.12% dengan kategori “Sangat tinggi” dan hasil belajar psikomotor mahasiswa dengan perolehan nilai 80 dengan kriteria “Baik”.

This research aims to determine whether there is an influence of applying the Problem Based Learning (PBL) Model with the Technological, Pedagogical, and Content Knowledge (TPACK) Approach on the historical learning outcomes of high school students of Sultan Iskandar Muda Medan. This study uses a quasi-experiment research method. The population in this study involves all students of class XI of High School (SMA) Sultan Iskandar Muda Medan, with a sample of class XI of Social Sciences (IPS) 1 as an experiment class and class XI of Social Sciences (IPS) 3 as a control class selected by simple random sampling method. The experiment class is taught with the PBL Model with the TPACK Approach, while the control class is taught with the Discovery Learning Model. The research instrument used is in the form of test questions totaling 25 multiple choice questions that have been declared valid. In this study, two stages of the test were given, namely pretest and posttest, in the form of multiple-choice questions that have been declared valid. The pretest is given to both sample classes to determine the student's initial ability before being given treatment, while the posttest is given to both sample classes to determine the final ability of learners after treatment. Based on posttest data, the experiment class obtained an average score of 80.3 and an average score in the control class of 68.4. The data proved to be a normal and homogeneous distribution through statistical test analysis, so a hypothesis test was carried out, namely a one-party t-test that showed a significance level of α = 0.05. Thus, Ho was rejected, and Ha was accepted, meaning that there was an influence of the PBL Model with the TPACK Approach on the historical learning outcomes of the high school students.

This research development is motivated by low learning outcomes Art Culture students of class XI software engineering 1 SMK Negeri 14 Medan. This study aims to (1) describe the design of blended learning development, (2) to describe the validity of the blended learning development result, and (3) to know the effectiveness of the use of blended learning on the subjects of Art Culture. The type of this research is development research using ADDIE model. Data in the study was collected using document recording method, questionnaire, and test. Instruments used in data collection are document recording reports, questionnaire sheets, and multiple-choice objectives. The collected data were analyzed by qualitative descriptive analysis technique, quantitative descriptive analysis technique, and inferential statistical analysis technique/inductive t-test. The results of the research show that (1) the design of blended learning development through ADDIE model consisting of analysis, design, development, implementation, and evaluation, (2) validation product validated from expert and user review with (a) subjects showed excellent predicated blended learning (90.53%); (b) the results of the design review indicated that blended learning was very good (93%); (c) the results of the media review indicated that blended learning was very good (95%); (d) individual trial results, small group trials, and field trials showed that blended learning predicate very good (98.82%), good (87.84%), and very good (92.55%), (3) on the efficacy test of blended learning shows that the result of t-count (22.07) t-table (2.007). This means, there are significant differences in student learning outcomes between before and after using blended. Thus blended learning is developed effectively to improve Art Culture learning outcomes.

This research departs from the problem of how the initial conditions of learning in the Department of Family Welfare Education (PKK), how to implement the collaborative learning model, how to implement the collaborative learning model through teaching practitioners in the Department of Family Welfare Education (PKK), and how it affectsthe improvement of the quality of learning and the implementation of the Merdeka Belajar Kampus Merdeka curriculum.The research methods used include (1) a Research and Depelopment approach to produce guidelines for the implementation of teaching practitioners in the Department of Family Welfare Education (PKK) and (2) a descriptive quantitative approach to determine the implementation of teaching practitioners in the Department of Family Welfare Education (PKK), toimprove the quality of learning and the Merdeka Belajar Kampus Merdeka curriculum (MBKM). The research respondents involved were lecturers in the Department of Family Welfare Education (PKK), Practitioners from the Industrial and Business World (DUDI), and Students. The results of the study are expected to produce Teaching Practitioner Guidelines in the Department of Family Welfare Education (PKK), because this guideline is very important as a standard operating procedure for the implementation of teaching practitioner activities on campus so as to be able to increase the partnership between the Department of Family Welfare Education (PKK), with DUDI and the successful implementation of the curriculum Merdeka Belajar Kampus Merdeka (MBKM). Meanwhile, the results of a descriptive quantitative analysis of the influence of teaching practitioners in the Department of Family Welfare Education (PKK), improving the quality of learning and developing the MBKM curriculum will provide recommendations in the formulation of policies for achieving IKU-4, namely teaching practitioners on campus
