Perceptual Data as a Tool

by Rhonda Jindra, Kunal Dash, and Justine Yeo

Purpose for Today’s Session

• Understand the importance of perceptual data

• Investigate a variety of tools that support the analysis of perceptual text data

Perceptual Data

Data Types

Why Perceptual Data?• One of the four types of data that should

be looked at for school improvement• Measures attitudes of students, school

staff, and parents toward the school environment (education, social, physical, etc.)

• Reflects reality of the stakeholder and guides behavior

• Without it, data is incomplete and may lead to less than optimal decisions

The Perceptual Survey• Questionnaires from Education for the

Future• Questionnaires by group:

•Student (Elementary, Middle, High School)•Staff•Parent (K-8th Grade, High School)

The Perceptual Survey: Close-Ended Questions

The Perceptual Survey:Open-Ended Questions

The Perceptual Report

The Current State• Perceptual data also used to improve

data literacy among school staff by having them analyze and interpret graphs in the reports

• However, methods for analyzing perceptual text data have not been explored yet

• Text data provides very rich insights for continuous improvement

Resource for Analyzing Perceptual Data

• Strengths; Challenges; Implications; So What, Now What?

• Across Surveys: Agreements and Disagreements (Student, Staff, Parent)

Visualizing Text Data

Using Word Clouds• Various off-the-shelf tools: www.wordle.com and www.worditout.com • Example from www.worditout.com:

• Step 1: Go to www.worditout.com; more specifically http://worditout.com/word-cloud/make-a-new-one • Step 2: Copy text data from Word, Notepad or Excel into the box titled “Original text”• Step 3: Click “Generate”• Step 4: Repeat until satisfied with design of generated world cloud

• Bigger words signify more frequently occurring words
