Model persamaan struktural (SEM) sangat berguna untuk mengetahui apakah suatu model antar variabel laten, variabel indikator fit dengan data yang diperoleh. Ketika data yang diperoleh cukup besar dan berhirarki maka diperlukan analasis penyesuaian dalam model struktural tersebut. Penyesuaian tersebut adalah dengan memasukkan variabel random efek dari tiap tingkatan hirarki. Variabel random untuk 2 level hirarki yaitu variabel random efek level-1 dan level-2. Metode estimasi yang digunakan dalam penelitian ini adalah maksimum likelihood (ML). Penggunaan metode ML ini merupakan metode yang umum dipakai dalam estimasi parameter dalam SEM namun mengalami kendala ketika terdapat data hilang. Sehingga algoritma ekspektasi-maksimasi (EM) diperlukan untuk mengestimasi data hilang.

Many ethnomathematical studies focus on Indonesian culture, particularly traditional dwellings, although research into the mathematical notions of the Tajug House is sparse. There has been no previous research that examines the Tajug House form the aspect of geometry. Tajug houses are becoming increasingly rare. Nowadays students are less familiar with traditional house types. As a result, this study investigates the mathematical principles found in traditional Tajug houses in Java, and how these notions might be integrated into educational curriculum to conserve cultural heritage while also improving mathematics learning. This study used an ethnographic approach, to investigates the Tajug House's design through a literature review, expert interviews, and observations. The data obtained were analyzed based on mathematical and Tajug House knowledge by author to see the existence of mathematical concepts in the tajug house. The findings reveal significant geometric concepts, including plane geometry (square, triangle, trapezoid), solid geometry (cuboid), and geometric transformations (reflection). Square found in the base of the house, triangle found in the side of the roof, and trapezoid found in the base of pillar. Cuboid found in the pillar. Reflection found in the base of the house. These results suggest that Tajug Houses can effectively become one of the learning media to geometry subject in schools, demonstrating practical ethnomathematics applications. The learning process can utilize the GeoGebra application. By linking cultural heritage with mathematical education, this research promotes a deeper understanding of both subjects. Future studies should evaluate the effectiveness of Tajug House-based learning in improving students' math comprehension and cultural appreciation.

Previous studies have tried to improve students' independence in online mathematics learning. However, the Flipped Learning model integrated with GeoGebra is scarce as none of the existing syntaxes accommodate the model. As the existing syntax is based on three phases: pre-class activity, in-class activity, and post-class activity. This research aims to develop GeoGebra-based Flipped Learning syntax to increase students' independence in learning mathematics. The main difference between the existing syntax and the developed one is the integration of GeoGebra in the pre-class activity. The integration is based on previous studies showing that using GeoGebra can improve student’s learning achievements. It research employed the Design-Based Research (DBR) model involving 125 second-year undergraduate students of a private university in Indonesia. The syntax results were obtained from the study, indicating an increase in the average value of student independence in learning mathematics based on learning independence, confidence, level of discipline, sense of responsibility, level of initiative, and self-control. This developed syntax is expected to help teachers streamline online mathematics learning.

The Covid-19 pandemic has forced an immediate transition from face-to-face learning in classrooms to online learning, including math learning. Mathematics with abstract working objects is not easy to learn online. So, an excellent self-regulated learning ability is required. So far, many efforts have been made to improve self-regulated learning in mathematics learning. However, there are still gaps in improving students' self-regulated learning ability in online mathematics learning, especially in relation to the integration of GeoGebra into the Flipped Learning approach. The purpose of this study is to examine the effectiveness of integrating GeoGebra into the Flipped Learning approach to improve students' self-regulated learning ability in learning mathematics online during the Covid-19 pandemic. This research is a quasi-experimental study with a pretest-posttest control group design to compare the effectiveness of a GeoGebra-integrated Flipped Learning approach. A conventional Flipped Learning approach and a conventional learning approach increase students' self-regulated learning level in constructing their understanding of mathematical concepts during online learning in the Covid-19 pandemic. The study involved 60 students randomly selected from one of Indonesia's private universities. They were divided into three groups representing each approach. Pretest and posttest results were quantitatively analyzed using Normalized Gain (N-Gain) Score, Cohen's d effect size, and statistical descriptive. The analysis results revealed that GeoGebra-integrated Flipped Learning is more effective in increasing students' self-regulated learning level in online mathematics learning than the other two approaches. It is expected that the results of this study can provide insights into alternative solutions for improving the quality of online mathematics learning by increasing the level of self-regulated learning of students.
