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. The activity was implemented collaboratively, where students observed, experimented, and drew conclusions together under teacher guidance, without the use of individual worksheets. Using a participatory observation method, the research described students’ engagement, reactions, and learning behavior during the process. Findings revealed that soap bubbles containing added sugar demonstrated greater stability and a longer lifespan compared to those without sugar. Students showed high levels of enthusiasm, curiosity, and active participation throughout the experiment. The activity not only fostered engagement but also enhanced students’ gross motor coordination, observation skills, and early scientific reasoning. Furthermore, it encouraged cooperative learning and communication among peers. The results highlight the effectiveness of simple laboratory-based learning as a medium to introduce scientific inquiry at the elementary level. The “Magic Bubbles” activity aligns with the inquiry-based learning approach in science education, emphasizing direct experience, experimentation, and concept discovery through observation and guided reflection. This study demonstrates that contextual, play-based science activities can meaningfully improve motivation and conceptual understanding among young learners.

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.

The rare of English in Indonesia in communicating in everyday life one of the reasons students have difficulty in memorizing and understanding English. Because of this, the author made a study that aims ti find out how much influence the Total Physical Response (TPR) learning method hason the learning outcomes of fourth grade elementary school students at SDN Lemah Duhur III.
