This study aims to identify students' learning obstacles in the process of understanding one-variable linear equations in grade VII, develop an appropriate learning trajectory using a Realistic Mathematical Education (RME) approach, and produce an effective learning design to reduce these obstacles through generative models. The research adopts a design research methodology consisting of three main stages. The first stage, preparation for the experiment, includes a literature review and analysis of teachers’ instructional practices to develop a Hypothetical Learning Trajectory (HLT) for one-variable linear equations. The second stage, design experiment, involves testing the designed learning activities through a pilot experiment and teaching experiment. The third stage, retrospective analysis, compares actual classroom observations with the initial HLT to refine and validate the learning trajectory. The research subjects include seven grade VII students in the pilot experiment and 44 students from SMP Negeri 2 Mataram in the teaching experiment. Data collection methods include tests, observations, interviews, and documentation, with retrospective analysis used to generate a validated Local Learning Trajectory (LLT). The findings reveal several epistemological obstacles experienced by students, such as difficulties in applying fundamental arithmetic concepts (addition, subtraction, multiplication, division) within the context of linear equations. Students also struggled with concept recognition, representation, and interpretation of linear equations in various forms. The developed LLT proved effective, as students demonstrated improved understanding and were able to follow the learning sequence meaningfully. Retrospective analysis confirmed that the LLT successfully addressed and reduced students’ learning obstacles in mastering one-variable linear equations.

The problem in this study is to determine what is the effect of the number tube game on the symbolic thinking ability of 4-5 year olds. The aim is to reveal whether there is a number tube game on the symbolic thinking ability of 4-5 year old children at Menara Laut State Kindergarten, Leato Utara Village, Dumbo Raya District, Gorontalo City. The type of research used is a quantitative experiment. The subject of this study is how to determine the effect of the number tube game. The method used in this study is the observation and documentation method. Based on the results of the observation, it was found that the symbolic thinking ability in recognizing numbers in children has not developed optimally. Although teachers have tried to introduce numbers, most children still have difficulty in naming, ordering, and writing numbers. Children also need teacher assistance to understand numbers 1-10 and distinguish between certain numbers such as 6 and 9. Therefore, a more effective and fun learning strategy is needed to help children understand the concept of numbers symbolically. In this case, it can be concluded that improvements through the application of the number tube game. This game was chosen because it is simple, easy to use, and in accordance with the characteristics of early childhood. Through a play-while-learning approach, children are expected to be able to recognize numbers more easily.

This study investigates the effect of added sugar on the stability of soap bubbles through a hands-on science activity titled “Magic Bubbles” conducted with third-grade students at SDN 1 Karangrejo.

This study compares the performance of two deep learning models, namely Convolutional Long Short-Term Memory (ConvLSTM) and Long-term Recurrent Convolutional Network (LRCN), in the task of recognizing human activity from videos. Human activity recognition is an important field in computer vision with many applications, such as security monitoring, human-computer interaction, and social media-based video analysis. ConvLSTM is a model that combines convolution operations with long-term memory LSTM, thus capable of capturing spatial and temporal information simultaneously. This approach is ideal for processing video data sequences that have spatial and temporal dimensions. On the other hand, LRCN combines the power of spatial feature extraction from Convolutional Neural Network (CNN) and temporal sequence modeling through Recurrent Neural Network (RNN), specifically LSTM, to understand movement patterns in videos. The study used the UCF50 dataset consisting of 50 activity classes, but was limited to five classes for the focus of the experiment. The dataset was divided into 80% for training and 20% for testing, and the model was drilled for 50 epochs using early stopping to prevent overfitting. The results show that both models have high training performance. ConvLSTM achieved a training accuracy of around 98% and a validation accuracy of 90%, while LRCN achieved a training accuracy of 99.5% and a validation accuracy of 88%. Although ConvLSTM demonstrated good stability on the validation data, further testing using TikTok videos as real-world data showed that LRCN had a higher confidence level in recognizing activities, with most predictions achieving confidence scores above 80%. This difference in performance indicates that while ConvLSTM excels in generalizing on training data, LRCN is more robust to real-world data variations.
