1 Overview The Value of Qualitative Data
What is Qualitative Data Data that approximates or characterizes but does not measure the attributes, characteristics, properties, etc., of a thing or phenomenon. Qualitative data describes, whereas quantitative data defines.
Qualitative vs. Quantitative Data • Quantitative Data • Deals with numbers. • Data which can be measured. • Length, height, area, volume, weight, speed, time, temperature, humidity, sound levels, cost, members, ages, etc. • Quantitative → Quantity • Qualitative Data • Deals with descriptions. • Data can be observed but not measured. • Colors, textures, smells, tastes, appearance, beauty, etc. • Qualitative → Quality
Qualitative vs. Quantitative Examples: Oil Painting • Quantitative Data • picture is 10" by 14" • with frame 14" by 18" • weighs 8.5 pounds • surface area of painting is 140 sq. in. • cost $300 • Qualitative Data • blue/green color, gold frame • smells old and musty • texture shows brush strokes of oil paint • peaceful scene of the country • masterful brush strokes
Qualitative vs. Quantitative Examples: Students • Quantitative Data • 672 students • 394 girls, 278 boys • 68% on honor roll • 150 students accelerated in mathematics • Qualitative Data • friendly demeanors • civic minded • environmentalists • positive school spirit
Collecting Qualitative vs. Quantitative Data • Quantitative Data • Primary (original) data • Questionnaires, measurement • Secondary (2nd or 3rd party) data • Existing research, library searches of statistical data • Qualitative Data • Focus groups • Observations • Interviews • Open-ended survey questions • Case studies • Record reviews
2 Case Example Review of a Mixed-Methods Evaluation
Intro to the Teacher Quality Enhancement Project (TQE) • 5-year project • Focused on: • Middle school student math and science achievement • Teacher preparation • Middle school licensure • Culturally Relevant Pedagogy
The Teacher Quality Enhancement Project • TQE project entailed: • Pre-service coursework • Pre-service field experiences • In-service mentoring • In-service 4-9 licensure program • Summer camp • Scholarships
Data Collection • Quantitative Methods • Secondary data analyses • State test scores • Summer camp test scores • Project completion rates • Qualitative Methods • Interviews • Observations • Focus groups • Survey of students
Group Exercise: TQE Quantitative Findings • Pre-Service Teachers • 120 recruited ; 160 anticipated • 105 enrolled • 69 identified as having received the “treatment” • Exposure varied greatly • 60 completed at least one urban field experience • 38 completed a teaching degree • 21 were hired as teachers in an urban district
Group Exercise: TQE Quantitative Findings • In-Service Teachers • Over 20 recruited; 160 anticipated • 18 enrolled • 11 completed 4-9 licensure program • 4 gained additional teaching license • Too soon to know if teachers continued teaching math and science for 5 years
Group Exercise: TQE Quantitative Findings • Middle School Students • Participation in the summer camp was a significant predictor of achievement test scores
Group Exercise: TQE Qualitative Findings • Pre- and in-service teachers overwhelming felt better equipped to deliver culturally relevant lessons • Pre-service teachers felt that the field experiences gave them valuable insight into teaching in urban environments that coursework could not provide • The summer camp provided a laboratory where pre-and in-service teachers felt safe to experiment with lesson plans
Group Exercise: TQE Qualitative Findings • Pre-service teachers were able to matriculate between five different colleges and universities to earn a degree • Four colleges and universities collaborated to develop and implement a 1-year alternative licensure program • Pre-service teachers developed relationships with students and colleagues that carried over into their teaching careers
3 Takeaways
Cons Against the Use of Qualitative Methods • Limited generalizability • Difficult to make quantitative predictions • More difficult to test hypotheses and theories • May have lower credibility with some administrators and commissioners of programs • Data collection and analysis are more time-consuming • Potential for researcher bias
Pros For the Use of Qualitative Methods • Data based on participants’ own experiences (insider’s view) • Useful for studying a limited number of cases • Useful for describing complex phenomena • Can conduct cross-case comparisons and analysis • Can describe phenomena in rich detail • Contextual and setting factors can be identified • Allows for the study of dynamic/evolving processes
Pros For the Use of Qualitative Methods • Can produce a tentative but explanatory theory about a phenomenon • Can determine how participants interpret “constructs” under study • Data collected in naturalistic settings • Responsive to local situations, conditions, and stakeholders’ needs • Allows for the determination of causes of a particular event
