Interactive visualization is becoming a more prominent feature of reporting. Business analytics packages tend to stress the ease eith which data can be played with by non-experts. Allowing students to explore aspects of complex data rather than simply telling them what you see can be a powerful tool for learning as explored in the readings. Within the RStudio universe this functionality is accomplished through the Shiny ecosystem. A web-app designing interface that allows web-apps to be built from within R with limited knowledge of javascript or html.
The purpose of this project is to build a couple of basic Shiny Apps and then create an interactive visualization of some midterm test data that can aid student learning. This dashboard consists of skill mastery for each student based on the midterm results, which can be seen below. The skills are as follows: coding, decision trees, just-in-time-learning (JITL), neural networks, natural language processing (NLP), social network analysis (SNA), substantive meaning from the analysis (Substantive), data visualizations (Viz), and data wrangling. It also includes scatterplot which displays the relationship between the student's grades, total time spent on the midterm and total click count where the user chooses the variables for the x-axis and y-axis and what variable to color by. Each data point on the scatterplot represents student's data.
