Abstract

This research investigates the impact of Problem-Based Learning (PBL) on students’ mathematical representation abilities within the context of mathematical modeling, with a particular focus on the role of learning independence. The research employs a mixed-method sequential explanatory model to analyze the effectiveness of Problem-Based Learning and to categorize students’ abilities and independence levels. Conducted with class XI TL 2 at SMAN 1 Mranggen during the 2023-2024 academic year, the findings reveal that PBL significantly enhances students’ mathematical representation abilities. Moreover, learning independence is identified in two distinct categories–high and medium–which correspond with similar levels of representation ability. Students’ mathematical representation ability has two categories, namely high and medium. These insights underscore the importance of self-directed learning in fostering mathematical comprehension and skills.

Abstract

The purpose of this study is to explore how MathCityMap training for teachers can be designed and implemented in a hybrid setting. Design research has been carried out involving teachers from 34 provinces in Indonesia. A four-day model training program for indoor and outdoor activities in a hybrid setting has been designed. The core concept of designing modeling tasks and math trails, as well as the introduction to MathCityMap, were delivered in a hybrid mode between Indonesia and Germany. The activity continued with the development of MathCityMap Trails in city parks. Post-training activities were conducted in their respective places of origin, in schools, and in city parks. Participants have successfully designed trails in both their schools and the city parks where they live supported using Learning Management System. The findings of the MathCityMap team's review indicate that most of the trails fulfilled the requirements. The trainee teachers then disseminate their knowledge and experience to their colleagues. They also used MathCityMap Trails for classroom learning as well as other activities such as MathCityMap competitions and public educational activities. The hybrid environment helps to accelerate the attainment of training objectives while also broadening the program's reach and network.

Abstract

This study employed a Randomized Block Design (RBD) with five formulations of moringa flour (2.5%, 5%, 7.5%, 10%, and 12.5%), each repeated twice, resulting in a total of 10 experimental units. The analysis included both chemical tests (water content, ash content, fat content, texture, and flavonoid content) and organoleptic tests (aroma, color, taste, texture, and hedonic test). The results showed that the addition of moringa flour significantly affected the physical and chemical properties of the flakes.Flakes formulated with formula 5 (sago flour: moringa flour = 100:12.5) were identified as the best, based on the organoleptic test, with the highest overall liking score of 3.92. The chemical characteristics of Formula 5 flakes included a moisture content of 8.51%, an ash content of 1.35%, a fat content of 8.49%, a flavonoid content of 0.033%, and a texture score of 78.9%. In terms of sensory properties, Formula 5 flakes were preferred due to their distinctive yellowish-green color, flavor that subtly highlights the aroma of moringa, and crunchy texture.
