The learning strategy implemented in schools focuses on teacher centered learning caused the students' mathematical creative thinking skills are not optimally honed. Efforts to shift learning from teacher centered learning to student centered learning are the STEM approach aided google classroom so that students can develop mathematical creative thinking skills optimally. This study aims to determine the STEM approach aided google classroom to improve students' mathematical creative thinking skills in line and angle material. The research method used is descriptive qualitative. The research was conducted in class VII A SMP Negeri 1 Pucakwangi consisted of 28 students. The research subjects were determined using purposive sampling technique. The data analysis techniques were written tests, questionnaires and interviews. The results showed that the approach of STEM aided google classroom is a learning strategy that is able to transform teacher-centered learning into student-centered learning. Students can follow the learning well, interactive so that it runs effectively. The STEM approach is able to improve students' mathematical creative thinking abilities optimally. Mathematical creative thinking able are grouped high, medium and low based on the process and written test scores. The pre-test result showed 1 student (3.6%) was in high category, 7 students (25%) were medium, and 20 students (71.4%) were low. While the results post-test showed that 7 students (25%) were in high category, 19 students (67.9%) were medium, and 2 students (7.1%) were in the low. This shows that there is a significant increase from the low category to the medium and high categories.

<p class="AbstractEnglish"><strong>Abstract: </strong>Knowledge construction from the beginning before students get formal learning (preconceptions or students' initial concepts) often does not match the knowledge received by experts, and becomes a misconception. Misconceptions on students need to be diagnosed and given a solution to improve learning, so that misunderstanding of the material can be corrected. This study aims to determine the effectiveness of the constructivism approach with the 5E method to remedy misconceptions on sound wave material. This research is a qualitative descriptive study with a sample of students of class XI MIPA 2 in 1 Turi Senior High School. This study uses a two tier test instrument. In addition to using a two tier test, interviews were conducted on several students to confirm the answers to the two tier test. Based on the results data, it was found that learning using the constructivism approach with the 5E method was effective in minimizing the average of students' misconceptions of 26%.</p>

Corporate Social Responsibility (CSR) programs are considered crucial as they facilitate effective communication with customers and potential customers, while also fostering stronger bonds between customers and companies. This journal article investigates the impact of Corporate Social Responsibility (CSR) in Social Media on Brand Advocacy Behavior, mediated by Customer Engagement (CE), Customer Company Identification (CCI), and Brand Trust. The study involved a sample of 239 customers from 14 banks, comprising 4 banks in the KBMI 4 category and 10 banks in the KBMI 3 category, with account tenure exceeding six months. The survey was completed through an online questionnaire, and data analysis was performed using Structural Equation Modeling (SEM). The findings of this research revealed that CSR, mediated by Customer Engagement, Brand Trust, and Customer Company Identification, has an overall positive effect on Brand Advocacy Behavior among bank customers in Indonesia. This study is based on the social identity (SI) theory, which is widely utilized to explain the behavioral patterns of individuals in diverse contexts. The presence of various psychological factors as mediators substantiates the significant role of CSR in shaping the behavior of specific individuals. This research underscores that banks are not solely profit-oriented, but also actively engage in sustainable CSR initiatives. The implications of this study are particularly relevant to the banking sector, emphasizing the significance of communicating CSR initiatives on social media in fostering meaningful customer relationships and promoting Brand Advocacy Behavior.
