Welcome to my dashboard! This is where I am building my work for the EDLD 652 Data Visualization Final Project. I hope you enjoy coding as mush as do!

The dataset used in this project is from the International Computer and Information Literacy Study (ICILS) Teacher Panel 2020, retrieved from the International Association for the Evaluation of Educational Achievement (IEA). ICILS investigates how teachers integrate technology into their teaching practices across different educational systems: Finland, Denmark, and Uruguay.

For more details about the study and its findings, visit: Data, ICILS, Report: Changes in Digital Learning During a Pandemic—Findings From the ICILS

In this project, I explored how teachers ICT use frequency in relate with school’s attitude toward technology and the disciplines.

Research Question One

What is the relationship between teacher’s information and communication technology (ICT) use frequency with their school’s attitude toward using ICT technology in the classroom? (This question is aiming to explore institutional attitude toward ICT influence individual teacher behavior in adopting technology for teaching).

Research Question Two

What is the relationship between teachers’ technology use in the classroom and their major teaching subjects? This question aims to explore whether teachers in different subject areas (e.g., mathematics, sciences, language arts) use technology more frequently compare to their peers in other subjects).

Here is the first try via datasummary_skim function from the modelsummary package. Considering the nature of our subset data, it doesn’t show much details about teacher participant in the year of 2018 and 2020 respectively.

At here, I added output = "gt" to apply functions from the gt package within datasummary_skim. Surprisingly, it worked! gt package gives me flexibility to customize my table. However, this version of summary table looks still robust.

I then decided to subgroup the dataset by country and year to show the counts and percentage for each category. To highlight the highest level of ICT use frequency in the table, I used tab_style and the location argument to map the highlights on the tabel. I also choosed a blind fridenly color in this process. This version was almost to what I need, but the whole table still needed further adjustment.

ICT Use Frequency Trend

Column

Final plot

Column

Version 1

The initial attempt helps me to map as much information as possible on a stack bar plot. However, it looks very busy and may not deliver the message efficiently.

Version 2

In my second attempt, I adjust the position of bars and applied scale_fill_OkabeIto() to make it color-blind friendly.

Version 3

I tried coord_flip()in this attempt mainly because the level labels on the x-axis took too much of the lower space. However, we can see all the key information mapped on this plot are either clustered or separated. The overall flow is not good.

ICT Use Frequency and School ICT Priority

Column

Final plot

We conducted a Chi-squared goodness-of-fit test with an alpha-trheshold of 0.05, and we reject our null hypothesis. In the population from which the sample for this study was drawn, we did detect statistically significant relationship, on average, between school ICT priority and their teachers ICT use frequency in Finland (\(\chi^2\) = 15.655, df = 4, p-value = 0.0035).

Column

Version 1

My first attempt was to map the recoded school priority with a stack bar to make it vertically visuable, but it was difficult to tell the difference across different levels of ICT use frequency.

Version 2

I applied scale_fill_viridis_d to ajust the color for my plot. In addition, I use scale_y_log10 to adjust the scale of y-axis. However, the change of scale does’t show the disparity between school ICT priority.

ICT use in different subjects

Column

Final plot

Column

Version 1

My first thought for this plot was a heatmap, but after I constructed one, I found the darkest purple shades are hard to differentiate. In addition, the heatmap doesn’t give much details on the difference among each countries.

Version 2

I then tried geom_bar to separate the ICT use in different subjects by country and years. It is important to show the difference between 2018 and 2020 because thses two years demonstrate the years before and after the pandemic.

Version 3

In this plot, I converted counts to percentages and flips bars horizontally.
