Abstract

Many studies have developed learning media, but few studies focus on developing learning media in ele-mentary schools using Genially and studying teachers' perceptions of Genially learning media. This study aims to determine teachers' perceptions of hybrid learning media with a more accurate and precise method, namely the item response theory (IRT) from the Rasch model. The survey was carried out by distributing a Likert scale questionnaire of 19 statements. Moreover, the subjects were 45 elementary school teachers in Riau Province, Indonesia. The results showed that they positively perceived the developed genially-based learning media. Genially learning media can support teachers in teaching. Based on these results, teachers need to develop skills in making various technology-based media, in order to support hybrid learning.

Abstract

Objective: Fuzzy clustering algorithm is a partition method used to assign objects from a data set to a cluster by marking the average location. Furthermore, Fuzzy Subtractive Clustering (FSC) with hamming distance and exponential membership function is used to analyze the cluster center of a data point. Therefore, the purpose of this research is to determine the number of clusters with the best quality by comparing the Partition Coefficient (PC) values for each number produced. Methods: The data set which is heart failure patient data is 150 data obtained from UCI Machine Learning. The data consists of 11 variables, including age , anemia , creatinine phosphokinase , diabetes ejection fraction , high blood pressure , platelets , serum creatinine , serum sodium , gender , and smoke . It simulated and processed using Fuzzy Subtractive Clustering Algorithm, Jupyter Notebook Software with Python programming language. Result: The results showed that the most optimal number of clusters is 3, which are selected based on the largest PC value. Conclusion: Based on the results obtained, the highest P value is in cluster 3, therefore heart failure can be grouped into 3, namely low, moderate, severe.
