This study is called classroom action research (CAR). This study was carried out at SMA Negeri 2 Rejang Lebong. For the 2018-2019 academic year, the research subjects were 28 class X Language students. This study was carried out during March and April of 2019. In this study, three approaches were employed to collect data: the test method, the observation method, and the documentation method. Following the collection of data, it is analyzed using a descriptive percentage approach. According to the findings of this study, student success climbed from 21.42% to 71.43% in Cycle I and then again to 85.19% in Cycle II. This rise has an impact on the rise in learning achievement. This is reflected in the rising average value of students. The average student score climbed from 67.71 with a percentage of student learning completeness of 21.42% in the pre-cycle to 77.43 with a percentage of student learning completeness of 71.43% in cycle I and 85.44 with an 85.19% completeness in cycle II. As a result, it is possible to conclude that using the group inquiry (GI) learning approach can increase student success in economic courses.</p> Nurcaya Megawati Copyright (c) 2023 Nurcaya Megawati https://creativecommons.org/licenses/by-sa/4.0 2023-09-22 2023-09-22 3 2 61 70 10.52760/ijerd.v3i02.43 @GURUKUMRD: the Greatest Way to Learn English Vocabulary https://e-journal.yayasancec.or.id/index.php/corolla/article/view/41 <p>Social media has impacted teenagers all around the world to be aware of the benefits of mobile phones for acquiring information, entertainment, and edutainment during the previous decade. 21st-century learners often favour Instagram, which is a well-liked social networking platform. The researchers seek to examine how undergraduate students in Indonesia use @gurukumrd Instagram to learn English vocabulary. This study presents a case study of how students learn about learning activities through the @gurukumrd account. Braun and Clarke (2006) obtained data through semi-structured interviews as an instrument and evaluated it qualitatively using thematic analysis. The participants were students in the sixth and eighth semesters of one university in West Java, Indonesia. The findings of this study are; Students acquire knowledge independently, select vocabulary and pronunciation resources, learn in a short period of time through @gurukumrd, memorize the vocabulary, imitate the pronunciation of the vocabulary, and engage in daily dialogue using the vocabulary. This finding indicates that students learning vocabulary through the @gurukumrd Instagram account valued time flexibility, effectiveness, independent learning, and interest-based learning.</p> Santiana Santiana Akhiria Hadiningrum Agis Andriani Copyright (c) 2023 Santiana Santiana, Akhiria Hadiningrum , Agis Andriani https://creativecommons.org/licenses/by-sa/4.0 2023-10-22 2023-10-22 3 2 71 84 10.52760/ijerd.v3i02.41 Religious Coping: Exploring the Resilience of Covid 19 Survivors https://e-journal.yayasancec.or.id/index.php/corolla/article/view/50 <p style="font-weight: 400;">The purpose of this study is to investigate adult religious coping strategies throughout the COVID-19 pandemic's quarantine phase. In-depth semi-structured interviews with thirteen adult COVID-19 survivors, ages forty to sixty, were undertaken. Open-ended questions on the state of the COVID-19 sickness, the psychological state, and the religious coping mechanisms used up until the point of cure were posed to the respondents. The information was categorized using thematic analysis. Three adult coping strategies—positive thinking, positive activity, and yielding to God—are shown by the classification results. According to this research, the respondent experiences resilience and serenity when coping with the COVID-19 virus when they practice good religious coping. This study demonstrates how adult respondents manage to endure till they heal, but additional investigation is required to comprehend how religious coping is employed by populations that are more vulnerable to pressures.</p> <p style="font-weight: 400;">&nbsp;</p> Zuhdiyah Zuhdiyah Copyright (c) 2023 Zuhdiyah Zuhdiyah https://creativecommons.org/licenses/by-sa/4.0 2023-10-30 2023-10-30 3 2 85 92 10.52760/ijerd.v3i2.50 Self Efficacy Enhancement of Public School Teachers through Cognitive Behavior Therapy https://e-journal.yayasancec.or.id/index.php/corolla/article/view/47 <p>This study explores how Cognitive Behavior Therapy (CBT) can help improve the self-efficacy of elementary school teachers in public schools. It focuses on four questions: (1) What are the Self-efficacy levels and concerns of Public-School Elementary Teachers? (2) How do Public School Elementary Teachers address their Self-efficacy concerns? (3) How different are the Self-efficacy levels of Public-School Elementary Teacher before and after undergoing CBT? (4) What guidance/wellness program using CBT can be proposed for the enhancement of Self-efficacy of Public-School Elementary Teachers? A mixed method explanatory design was employed, and out of 101 teachers from five schools in San Jose del Monte Bulacan, five were chosen to participate in CBT sessions. Quantitative findings utilizing the New General Self-efficacy scale present that majority of the teachers demonstrate moderate to high levels of self-efficacy. Qualitative data indicated the self-efficacy concerns of teachers including computer skills, aging, health issues, motivation, task alignment and time management. To address these, they resort to mediocre work, talk directly to concerned persons, seek help from relatives, become careful about health, and most commonly, resort to sleeping. The CBT sessions markedly increased the posttest results and the teachers reported considerable positive changes in their thinking. This research promotes the understanding of the self-efficacy of teachers and offers valuable insights for upgrading the well-being and effectiveness of teachers. It also highlights the potential of Cognitive Behavior Therapy as an effective intervention for enhancing self-efficacy and showcases the importance of tailored wellness programs in building the holistic development of teachers.</p> <p>&nbsp;</p> Toniruth Luaton Lorelei Vinluan Copyright (c) 2023 Toniruth Luaton, Lorelei Vinluan https://creativecommons.org/licenses/by-sa/4.0 2023-11-10 2023-11-10 3 2 93 106 10.52760/ijerd.v3i2.47 Empowering Learners on Mathematic Subject by Problem Based Learning and Metacognitive Strategy to Improve Reflective Thinking Competence https://e-journal.yayasancec.or.id/index.php/corolla/article/view/39 <p>Learning on math in the classroom has a one way teacher center, so&nbsp; the student will be un-active, the process of learning on math that could be done more concentrate on finishing the test&nbsp; that has procedural character only, that caused the student couldn’t finished a math problem that usually applied in the class, didn’t give a chance for the student to develop their competence of thinking, in which, one of them is reflective thinking competence. The fact above be an early thinking for the researcher, while the objective of the research will be focused on knowing the implementation of problem base learning and metacognitive in improving mathematic reflective thinking competence,&nbsp; analysing the lacknes on the implementation of problem based learning and metacognitive in improving mathematic reflective thinking competence, knowing &nbsp;the advantages&nbsp; based learning and metacognitive in improving mathematic reflective thinking. Research approach that used in this research is descriptive qualitative approach, by the setting of the research is SMK1 Pamekasan, with the math teacher and the student as the subject of the research. In data analysis, the researcher used Miles model. The result shown that teaching learning activities became more active, the students have developed thinking skills, enabling them to find the appropriate ways to solve the problems they face. The thinking process involved enables the students to solve mathematical problems and has a connection with their ability to remember and recognize relationships between mathematical concepts, understand cause-and-effect relationships, analogies or differences.</p> <p>&nbsp;</p> <p>&nbsp;</p> <p>&nbsp;</p> <p>&nbsp;</p> Abd Ghofur Rofiatul Andawiyah Ali Said Al Mattari Copyright (c) 2023 Abd Ghofur, Rofiatul Andawiyah, KJ Vargheese https://creativecommons.org/licenses/by-sa/4.0 2023-12-07 2023-12-07 3 2 107 114 10.52760/ijerd.v3i2.39
