Abstract

This research is motivated by the low mathematics learning outcomes, which is a crucial issue in the development of education, particularly at SMA Negeri 9 Semarang. This study is an Action Research (PTK). The aim of this research is to determine whether Teaching at the Right Level (TaRL) with Problem-Based Learning (PBL) can improve students' mathematics learning outcomes. The subjects involved in this study were 36 students from class XII SMA N 9 Semarang. The research was conducted in two cycles. The results of the research show that teaching using the Teaching at the Right Level (TaRL) approach with Problem-Based Learning (PBL), starting from cycle 1 to cycle 2, resulted in an improvement in students' mathematics learning outcomes. In Cycle I, the percentage of learning outcomes reached 66.67%, which increased to 88.89% in Cycle II. The implementation of the Teaching at the Right Level (TaRL) approach with Problem-Based Learning (PBL) has proven to enhance the mathematics learning outcomes of students in class XII SMA N 9 Semarang.

Abstract

Pricing and cost planning are critical aspects of business management, especially for small enterprises like the "Cakemyday" cake shop. Proper financial planning ensures sustainability and profitability in a competitive market. This study aims to analyze the financial feasibility of "Cakemyday" by calculating the Break-Even Point (BEP) and determining the optimal selling price based on cost structures and demand functions.A quantitative approach was employed, utilizing financial data, including fixed costs, variable costs, and demand function analysis. The BEP calculation determined the minimum number of units required to cover all expenses, while the demand function was derived from historical pricing and sales data to understand consumer behavior.The findings indicate that "Cakemyday" needs to sell 78 units to reach BEP, with a contribution margin of Rp 90,000 per unit. Furthermore, to achieve a profit target of Rp 3,000,000, an optimal selling price of approximately Rp 188,000 per unit was determined. The demand function analysis revealed a negative correlation between price and quantity demanded, supporting strategic pricing decisions.The study concludes that understanding financial metrics and consumer behavior is essential for sustainable business growth. It is recommended that "Cakemyday" implement targeted marketing strategies and monitor pricing dynamics to enhance profitability. Future research may explore external factors affecting demand and conduct comparative studies with similar businesses.

Abstract

This study aims to determine the influence of ethnobotanically charged project-based learning-STEM models on students' critical thinking skills in biology learning. This type of research is a meta-analysis research. The inclusion criteria in this study are that the research must be relevant; research data was obtained from Google Scholar, Mendeley, ScienceDirect, ERIC and ProQuest; Research must be indexed by SINTA or Scopus, research published in 2023-2025 and have complete data to obtain effect size values. Data analysis with the help of the Jamovi application to calculate the effect size value, publication bias and homogeneity test. The results of this study concluded that the value of the summary effect size (d = 1.129; p < 0.005; Z = 9.890). These findings explain that there is an influence of the ethnobotanically charged project-based learning-STEM model on students' 21st-century skills in Science Learningcompared to the conventional model with a strong effect size category.

Abstract

This research describes the knowledge and beliefs of pre-service teachers about mathematics. Data collection of this research using written test of 143 mathematics pre-service teachers who have taken six semesters at Universitas PGRI Semarang, and interviewing of three pre-service teachers who are not consistent between knowledge and belief. The data are presented in the form of descriptive quantitative and analyzed qualitatively, including data reduction, data display, and conclusions drawing/verification. The results show that most of the knowledge of pre-service teachers are consistent with their beliefs. It is indicated that pre-service teachers’ knowledge has been internalized into a strong belief that affect their words and behaviors. The belief of almost half of pre-service teachers who become respondents changes because of lecturer activity effect. It can say that belief changes at any time, both the process of alteration and the formation of new beliefs as well as the reinforcement of the beliefs they have.

Abstract

social, cultural, and economic challenges faced by local communities(Yulianti, 2020); (Ali et al., 2024; Dewanto et al., 2023; Ichsan et al., 2023). This study examines ethnic involvement in community-based education by highlighting the power dynamics and ethical considerations that underlie the learning process and community empowerment. In the context of pluralistic community education, the involvement of ethnic groups is not only about participation, but also concerns bargaining positions, socio-cultural representation, and the challenges of maintaining justice and inclusivity. Through a qualitative approach based on literature studies and selected case studies, this study found that power inequality between education facilitators and local communities can hinder the process of social transformation. In addition, disregard for local values and norms often triggers resistance or misinterpretation of educational goals. Therefore, it is important to design a community-based educational approach that is sensitive to social dynamics, upholds participatory ethical principles, and strengthens community voices in decision-making. These findings recommend strengthening critical pedagogical practices that integrate local values with the goal of continuing education development.

Abstract

The 21st century demands education to equip students with academic knowledge and additional skills, such as innovative, productive, reasoning, programming, data literacy, problem-solving, and critical thinking to face the rapid world changes. This study aims to develop science inquiry skills from early childhood to support children in mastering skills needed in the 21st century. This research design is descriptive qualitative. Data was collected from 16 preschools by observations, interviews, and documentation. Researchers used NVivo software for data management and analysis. NVivo is a software application designed to assist researchers in organizing, analyzing, and visualizing qualitative data. The research results reveal that coding games can develop 7 primary science inquiry skills: arguing based on existing evidence, identifying problems, analyzing and interpreting data, evaluating and communicating, planning and conducting investigations, asking questions, and constructing explanations. This research suggests that more preschools carry out coding games in the learning process because coding games can develop children's science inquiry skills, which will be useful in children’s future careers.

Abstract

This study aims to analyze the influence of digital technology-based integrated STEM learning models on improving students' digital literacy through a meta-analysis approach. Digital literacy is an essential competency in the era of the Industrial Revolution 4.0, and STEM learning that integrates digital technology is believed to be able to facilitate the strengthening of these skills. This study examined 20 scientific articles published in the period 2015–2024 and met the inclusion and methodological quality criteria. The analysis was carried out using JASP. The results of the meta-analysis showed that the digital-based STEM learning model had a significant influence on improving students' digital literacy, with an average effect size value of 0.78 which was included in the large category. Subanalysis based on education level indicates that the strongest influence occurs at the secondary education level. These findings imply that the development of STEM-based learning curricula and strategies that are integrated with digital technology needs to be continuously encouraged to strengthen students' readiness to face the challenges of the digital world.
