The transition from face-to-face learning to distance learning has decreased student learning outcomes. Departing from this phenomenon, this research is presented as an effort to overcome various obstacles experienced by teachers and students during the COVID-19 pandemic. The researcher offers a model that can be used in virtual learning activities. Beginning with finding out the extent of the influence of the problem-based learning (PBL) model on accounting learning outcomes in class X Accounting 1 students at SMK YPKK Limbung. Research data obtained from the results of the test, observation, and documentation. Then analyzed using t-test which consists of simple linear regression analysis and product moment correlation. The findings in this experimental study resulted in a simple linear regression equation model with a value of Y=33,012+4.283X and a correlation coefficient value of 0.580. After students received learning using the PBL model through distance learning and were given a post-test, their learning outcomes also increased. In other words, the implementation of the PBL model has a significant and positive effect on accounting learning outcomes during the COVID-19 pandemic.

Education in the industrial era 4.0 must be adapted to the characteristics and skills of students demanded in the 21st century, one of the skills required is creativity. The data shows that the creativity of students in schools is still relatively low. Learning design must be designed to be able to build student's creativity. This study aims to analyze the feasibility of the Problem Based Learning (PBL) model to build student creativity in determining pH route of natural indicator. The method used in this research is descriptive with DbR design. DbR consists of 4 stages, problem identification and analysis, development prototype, testing and implementation, and reflection. This research was conducted only at the limited trial stage to see the feasibility of the Learning Design using the PBL model to build student creativity. The instruments used in this study were internal feasibility test sheets, external feasibility test sheets, TCOF, and creativity observation sheets. The results showed that the learning design with the PBL model is categorized as very feasible based on internal, external, and TCOF feasibility tests to develop student creativity and student creativity is categorized very well through learning using the PBL model.

Creative thinking skills are part of Higher Order Thinking Skills (HOTS) that aid students in problem-solving. Teachers have a responsibility to cultivate these skills by employing suitable learning models. The RADEC (Read-Answer-Discuss-Explain-Create) learning model offers an alternative approach for teachers to enhance student competencies. This study aimed to investigate the impact of a problem-solving-oriented RADEC approach through the colloidal topic on students' creative thinking skills. The research was conducted at a private high school in Cianjur Regency and involved 28 students from class XI. The pre-experimental method employed a one-group pre-test and post-test design. The findings revealed that this learning model effectively nurtured students' creative thinking skills. Students demonstrated significant improvements in various aspects of creative thinking, with percentages as follows: fluency (78.88%), flexibility (71.62%), elaboration (68.33%), originality (70.83%), and metaphorical thinking (61.11%). The pre-test and post-test scores indicated an increase in students' creative thinking skills, with an n-gain value of 0.5936, categorized as moderate. In summary, the problem-solving-oriented RADEC learning model proved effective in enhancing students' creative thinking skills in the context of colloidal material. This research has implications for teachers, urging them to consider implementing the RADEC model to foster the development of student's creative thinking abilities.

Hingga saat ini, kreativitas anak bangsa masih terus diupayakan dalam dunia pendidikan di Indonesia. Kreativitas ini termasuk salah satu Keterampilan Abad 21 merupakan aspek terpenting dalam mendukung kemandirian anak bangsa. Untuk itu, dalam kegiatan pembelajaran kreativitas diperlukan suatu model berbasis proyek yang memudahkan guru dalam menerapkannya meliputi 6 tahap, yaitu: Connecting, Restructuring, Elaborating, Applying, Tasking, dan Evaluating yang dikenal dengan istilah Model C-R-E-A-T-E. Penggunaan model ini secara blended learning bertujuan untuk membangun kreativitas siswa melalui pemanfaatan bahan alami ramah lingkungan dalam pembelajaran Sel Volta di sekolah. Metode yang digunakan adalah Research and Development (R&D) terhadap 20 siswa dari salah satu Sekolah Menengah Atas (SMA) di Bandung. Instrumen yang digunakan berupa Teaching for Creativity Observation Form (TCOF). Hasil penelitian menunjukkan bahwa kreativitas siswa terbangun secara signifikan selama mengikuti pembelajaran Sel Volta melalui Model C-R-E-A-T-E. Dengan demikian, dapat disimpulkan bahwa Model C-R-E-A-T-E sangat efektif untuk membangun kreativitas siswa dalam membuat Sel Volta yang ramah lingkungan.
