Grade 9 Computer Science: Case Presentations of Data Analysis

April 9, 2024

This semester, in the 9th grade computer class, when learning about data visualization, students used group learning to conduct case studies. The teachers assigned students a list of tasks and provided them with some learning resources for reference, allowing them to download them online and then work in groups for independent learning.

Amongst the case studies, one example was using visual charts to analyze the trend of some entities' quarterly financial cost changes in recent years. The choices also included the top 20 globally popular game rankings, as well as comparison of game publisher sales. Another interesting case was about the data analysis on the ingredients used in cooking in different countries around the world.

In the achievement presentation section, it could be seen that the students not only completed the tasks on the list, but also proposed their own innovative ideas. For example, some students came up with a unique method to quantify financial status, and another group of students used data correlation analysis to characterize the similarity between different ingredients, in order to classify similar cuisines. This can lead to the conclusion that similar ethnic cultures are likely to have similar cuisines. The whole process turned out to be a very effective learning experience.
