Analyzing K-12 Student Data for School Year 2021

Year 2020 has been a challenging year. On March 13, 2020, all public schools in California were shut down due to COVID-19. All students ended their 2020 school year in a remote learning setting. Early August, all students had to start school year 2021 remotely still. I work in a school district as a Database Manager in Southern California. Our school district is a K-12 school district and have roughly 50,000 students and 50 schools. I work in Information Technology department and my main role is to maintain and suport data in any information system that school district is using. Because of school closures since March this year, a lot of changes in the systems were made because students can physically go to schools to get instructions. Because of these changes, we were able to collect some new data points this school year to analyze. It is interesting to see what these new data points can tell us.

As a first step, let's upload our Jupyter notebook to Jovian.ml.

Data Preparation and Cleaning

Data source will be from our SIS (Student Information System). Our SIS is using Microsoft SQL Server as database server so I wrote a T-SQL script to pull student data from database server. Since student data is confidential, I didn't include any sensitive student data. I also replaced unique identififer for each school and student in SIS with some unique ID that I created just for this project.

Here is some information of data file I am using:

  • File name is data-science-project-2021-k12.csv.
  • Only students who are currently enrolled in school district are included in the file.
  • Fields included in the file are below:
    • SchoolType: Traditional or Year Round. (Year Round means these schools have year round schedule. Students are divided into different tracks to accommdate student populations)
    • EnrollmentType: Tradional or Virtual. (In summer, we gave parents oppurtunity to select learning model they would like to have for their kids once students can return to school. Virtual meaning remotely learning and Traditional meaning students would go back to school physically when condision is allowed.)
    • SchoolCode: Student's enrolled school. This data is created just for this project.
    • Track: Student's primary track.
    • Grade: Student's grade level in school year 2021.
    • GradeLevel: Elementary, Intermediate or High
    • StudentID: Student's unique identifier. This data is created just for this project.
    • HasLaptop: This is created on these conditions: 1. if student answered "Yes" on survey question "Do you have laptop access?" or 2. if student has checked out a laptop from district.
    • HasInternet: This is created on these conditions: 1. if student answered "Yes" on survey question "Do you have internet at home?" or 2. if student has checked out a hot spot from district.
    • LaptopCheckedOut: The student has checked out a laptop from district or not.
    • PCSurveyLaptop: Student's answer on survey question "Do you have laptop access?"
    • MiFiCheckedOut: The student has checked out a hot spot from district or not.
    • PCSurveyInternet: Student's answer on survey question "Do you have internet at home?"
    • PCSurveyInstrProg: Which instruction program (learning model) do you want to have? We assigned students into different learning models based on their response.
    • TotalStudentInHousehold: Total current students in our school district in the same household.
    • IsSED: Is the student in Socio-Economic Disadvantage group?
    • IsSPED: Is the student in Special Education program?
    • SPEDProgram: If the student is in SPED, which SPED program he/she is in?
    • IsEL: Is the student in English Learner program?
    • ELPAC: ELPAC proficiency level. ELPAC is an English Learner exam in California.
    • IsDLI: Is the student in Dual Immersion program? Dual Immersion is a program which offers bi-lingual learning environment.
    • IsGATE: Is the student in GATE program? GATE means Gift And Talented Education.
    • IsGNP: Is the student in GATE Magnet Program?
    • IsFoster: Is the student a foster student?
    • Gender: Student's gender.
    • Ethnicity: Student's ethnicity.
    • ParentHighestEdLevel: Parent's highest education level.
    • DaysEnrolled: Total days enrolled in school year 2021 up to 9/25/20.
    • DaysPresent: Total present days in school year 2021 up to 9/25/20.
    • PresentRate: This is calcualted by using DaysPresent / DaysEnrolled.
    • CountT1P_N_IDF: Count "N's" (for grade K-3) or "In Danger of Failing" (for grade 4-6) courses for elementary students for T1 term progress report.
    • CountT1_N_DF: Count of "N's" (for grade K-3) or "D's and F's" (for grade 4-6) courses for elementary students for T1 term marks. Only some students in year round schools have T1 marks so far.
    • CountQ1P_IDF: Count of "In Danger of Failing" courses for secondary (intermediate and high school) students for Q1 term progress report.
    • CountQ1I_DF: Count of "D's and F's" courses for secondary (intermediate and high school) students for Q1 term interim report. Only a few students get this mark.

It looks like max number of students in a household is 41. Not sure if this is bad data since 41 students in a household seems high. Let's find out.

In [13]:
data_raw_df[data_raw_df.TotalStudentInHousehold == 41]
Out[13]:

Since the data file was created without any confidential student information, there is no way to identify why there is a household with 41 students so I checked SIS directly. It turns out that there are 41 students with no Household ID in SIS (bad data). I need to contact school sites to have them to correct the data and also I need to change their "TotalStudentInHousehold" to 0.

In [14]:
k12_data = data_raw_df.copy()

Always make a copy of raw data before change data.

In [15]:
k12_data.loc[k12_data.TotalStudentInHousehold == 41, 'TotalStudentInHousehold'] = 0
In [16]:
k12_data.describe()
Out[16]:

Now max number of students in a household seems making more sense.

Here are some findings based on these integer columns:

  • Total active student count is 51,354.
  • Average number of students in a household in the school district is 1.74. Max number of students in a household is 7.
  • Average student enrolled days in this school year is 32.78. Max is 57. Because some elementary schools are year-round schools in our school district and their first day of school was 7/6/2020 so it is resonable students having 57 enrolled days.
In [17]:
k12_data['StudentCount'] = 1

Add a new column "StudentCount" so it is easier to count student in different category later.

Exploratory Analysis and Visualization

This section is to explore data points in the data file using visualization. There are some existing data points that I list here for people to understand our school district's basic demographic. New data points that we collected in school year 2021 due to COVID-19 school closures are listed here for exploring the possible analysis.

Grade Level

Let's check how grade level distribution looks like in our school district.

In [21]:
grade_level = k12_data.Grade.value_counts()
grade_level
Out[21]:
10    4350
09    4331

06    3822
04    3813
03    3609
02    3552
01    3474
KN    3035
KA     538
PS     303

IN       1
Name: Grade, dtype: int64
In [22]:
plt.figure(figsize=(10,6))
plt.title("Student Grade Level in School Year 2021")
sns.barplot(grade_level.index, grade_level);

In general, K-12 student counts are evenly distributed with high and intermediate school students (7-12) slightly more than elementary students (K-12). Some other grade levels that are not K-12 are for some Special Education students that receive our services so they have relatively low counts.

Ethnicity

How about ethnicty distribution? Let's find out.

In [23]:
ethnicity_count = k12_data.Ethnicity.value_counts()
ethnicity_count
Out[23]:
Hispanic                     27536
White                        11953
Asian                         7758
Black or African American     3284
Other                          823
Name: Ethnicity, dtype: int64
In [24]:
plt.figure(figsize=(10,6))
plt.title("Student Ethnicity in School Year 2021")
plt.xticks(rotation=45)
sns.barplot(ethnicity_count.index, ethnicity_count);

Hispanic ethnicity is a clearly winner here followed by White and Asian.

In [25]:
plt.pie(ethnicity_count, labels=ethnicity_count.index, autopct='%1.1f%%', startangle=180);

Same data but differnt chart here to show percentage of each ethnicity using pie chart. A little bit more than half of our studens are hispanic.

Virtual vs Traditional Setting

Newly collected in school year 2021

Because of COVID-19, all California schools began school year 2021 in a remote learning (virtual) setting. During summer time, our school district sent out a survey asking parents' preferred learning models (instruction programs) for their students. There are two selections: Virtual and Traditional. Schools schedule students into differnt enrollment types based on their survey answers. For those parents who didn't answer the survey, default enrollment type is Traditional.

In [26]:
k12_data.EnrollmentType.unique()
Out[26]:
array(['Traditional', 'Virtual'], dtype=object)
In [27]:
virtual_traditional = k12_data.EnrollmentType.value_counts()
virtual_traditional
Out[27]:
Traditional    38678
Virtual        12676
Name: EnrollmentType, dtype: int64
In [28]:
plt.figure(figsize=(10,6))
plt.title("Student Enrollment Type in School Year 2021")
plt.pie(virtual_traditional, labels=virtual_traditional.index, autopct='%1.1f%%', startangle=180);

Based on this pie chart, about a quarter of students are enrolled in Virtual settings in 2021.

Device Checked Out Status

Newly collected in school year 2021

Because of school closures, students can't physically go to school to receive instructions. Students now have to rely on technologies to attend online meetings with teachers or do their homework. In order to support some families who can't afford these technologies, school district has budget to purchase Chromebooks and hot spots for students to check out to use at home. Parents can make requests for Chromebook or/and hot spot on parent portal. Information Technology department gathers these requests and notifies parents to come to district office to pick up devices when inventory allows.

Let's check how many devices have been checked out since March, 2020.

In [33]:
laptop_checked_out = k12_data.LaptopCheckedOut.value_counts()
laptop_checked_out
Out[33]:
No     32752
Yes    18602
Name: LaptopCheckedOut, dtype: int64

Total 18,602 Chromebooks were checked out to students.

In [34]:
mifi_checked_out = k12_data.MiFiCheckedOut.value_counts()
mifi_checked_out
Out[34]:
No     43532
Yes     7822
Name: MiFiCheckedOut, dtype: int64

Total 7,822 hot spots were checked out to families. We only provide one hot spot to each household.

In [35]:
has_laptop = k12_data.HasLaptop.value_counts()
has_laptop
Out[35]:
Yes    42649
No      8705
Name: HasLaptop, dtype: int64
In [36]:
has_internet = k12_data.HasInternet.value_counts()
has_internet
Out[36]:
Yes    45106
No      6248
Name: HasInternet, dtype: int64

I created HasLaptop and HasInternet two fields based on two conditions for "Yes" when I wrote the SQL query to pull data:

  • If student doesn't request for a device.
  • If student has checked out a device from district.

Because we are still waiting for vendors to deliver Chromebooks and hot spots orders, we need to monitor how many students/families still need to check out Chromebooks or/and hot spots to support students' online learning experience.

Based on the numbers, we still have 8,705 students that will need to check out a Chromebook and 6,248 families that will need to check out a hot spot.

In [39]:
plt.figure(figsize=(10,6))
plt.title("Student Has a Laptop to Use?")
plt.pie(has_laptop, labels=has_laptop.index, autopct='%1.1f%%', startangle=180);

Based on this pie chart, there is still 17% of students in our school district currently don't have a laptop to use for attending school remotely.

In [40]:
plt.figure(figsize=(10,6))
plt.title("Student Has a Laptop to Use?")
plt.pie(has_internet, labels=has_internet.index, autopct='%1.1f%%', startangle=180);

And there is 12% of students in our school district currently don't have internet access for attending school remotely.
