Neoliberalism and its Impact on Indonesian Education: A Reflection

2024-01-22T04:04:39+00:00

In Indonesian education, this neoliberalism ideology is reflected in the increasing role of private educational institutions, the commercialization of education, and the rising cost of education. The result is negative impacts such as access inequality, declining education quality, and the influence of globalization that threatens local cultural identity. This research uses a literature review to explore neoliberalism's impact on Indonesia's education system. Data collection is done through scientific journals, then analyzed and discussed deductively-inductively. As an economic ideology championing market freedom, privatization, and deregulation, neoliberalism impacts education globally, including in Indonesia. The results of the literature analysis found that neoliberalism encourages the marketization of education, privatization of education, deregulation, and competition. Neoliberalism promotes social inequality, where the rich can access the best education while the poor can’t. To deal with neoliberalism and provide access to proper education for the community, the government first needs to increase supervision in education. Second, review the curriculum to include local values, promote cultural pluralism, and prepare students for global challenges. Third, provide holistic-inclusive education. Fourth, actively involving the community in education planning and decision-making. With these steps, Indonesian education can find the right balance between following the principles of neoliberalism that allow for innovation and efficiency while maintaining intrinsic values and providing equal access to education.

Therefore, the alternative hypothesis (Ha) is accepted and the null hypothesis (H0) is rejected, indicating that group counseling services contextual teaching and learning (CTL) methodologies are effective to increase students' self-confidence at SMP Negeri 2 Palangka Raya.

Application of Project-Based Learning on Geometric Transformation

2024-02-06T11:17:36+00:00

The success of implementing the PjBL learning model in the classroom lies in the teacher's ability to effectively design learning, motivate, support and guide students in the process of determining and completing the project. The aim of this research is to apply project-based learning (PjBL) to Geometry Transformation material for class IX junior high school students to find out how the learning process is perceived by students and teachers. This type of research is descriptive research with the research subjects being class IX middle school students. The research instrument is a lesson plan for 6 meetings, posttest, and mathematics disposition. The results of the research show that the implementation of the PjBL learning model in the classroom is less than optimal, as shown by the students' posttest results which have decreased compared to the pretest scores conducted by the teacher, the mathematics disposition questionnaire has also decreased. However, the project assignments in the form of videos and paintings for each group were completed well. The decrease in grades occurred because conditions at the research location experienced a disaster, namely "smog" around October 2023, this caused the learning process to run less than optimally.

Cognitive Level Analysis of Class VII Middle School Mathematics Textbooks

2023-08-18T06:13:09+00:00

This study aims to determine the suitability of the distribution of cognitive level questions in the “Matematika Kelas VII SMP” textbook published by the Kemendikbud written by Susanto, et al (2022) and the “Matematika Kelas VII SMP” textbook written by Mairing (2020).

This research is an evaluative study, using the discrepancy evaluation model. The data sources in this study were questions in the “Matematika Kelas VII SMP” textbook (Susanto, et al, 2022) (called textbook A) and the “Matematika Kelas VII SMP” textbook (Mairing, 2020) (called textbook B). Samples were taken using a proportional stratification random sampling technique to determine the number of samples taken in each chapter and the questions that became the research sample. The analysis of textbook questions was based on the cognitive level of the Revised Bloom's Taxonomy, and was evaluated by comparing the distribution of textbook cognitive levels to the cognitive dimensions of the TIMSS 2015 Assessment Framework.

Of the 135 questions analyzed in textbook A, the distribution of cognitive levels was 14.8% remembering, 46.7% understanding, 20.7% applying, 9.6% analyzing, 4.5% evaluating, 3.7% creating. Meanwhile, of the 188 questions analyzed in textbook B, the distribution of cognitive levels was 0.5% remembering, 40% understanding, 40.4% applying, 11.2% analyzing, 7.4% evaluating, and 0.5% creating. The results showed that the questions in textbooks A and B were quite good because there were each cognitive level according to the Revised Bloom's Taxonomy in both textbooks. However, the distribution of cognitive levels in textbooks A and B still does not match the proportions of the TIMSS 2015 cognitive dimensions. The distribution of cognitive levels according to the TIMSS 2015 Assessment Framework is 35% knowing (remembering and understanding), 45% applying (applying), and 25% reasoning (analyze, evaluate, and create). Realization of the findings in textbook A is 61.5% knowing, 20.7% applying, and 17.8% reasoning. While the distribution in textbook B is 40.5% knowing, 40.4% applying, and 19.1% reasoning. Both textbooks are still lacking in questions of the reasoning type (analyze, evaluate, create). Thus, both textbooks are of fairly good quality, but improvements need to be made by adding questions at the cognitive level of analyzing, evaluating, and creating.
