Qualities of Data Collection
Generalizability – not necessary; goal is to improve school or classroom
Validity – the data measures or represents what it is meant to
Reliability – accuracy of instruments for measurement

Questions to Ask
Do the instruments and methods we plan to use measure what they claim they do?
Do they measure the phenomena we are studying?
Are we collecting enough data?

Establishing Validity
Utilize peer to peer coaching
Engage in persistent and prolonged observations
Record data accurately
Member checks -- check in with respondents to discuss interpretation of data
Provide thick descriptions – describe setting, participants, interventions, and research methods in detail

Establishing Validity
Do a negative case analysis – explore diversity of interpretations
Identify any researcher bias
Confirmability -- create an audit trail
Present results to key audiences
Engage in reflective planning

Quantitative Designs
Measures the extent to which how well something is done Experimental: independent variable
manipulated while other variables are controlled
Causal comparative: attempt to discover ther cause of issue
Correlational: examines 2 variables to see if a relationship exists
Survey: discover a group’s status with regard to certain variables

Qualitative Designs
Describes the qualities of certain aspects of phenomenon Ethnographic: collection of data on may variables in
a naturalistic setting Naturalistic: observations in a natural setting Participant observer: researcher becomes
participant in the research Case study: in depth investigation used to
determine the relationship between variables and certain behaviors
Content analysis: analysis of written or verbal content of documents

Methods of Data Collection
Artifacts Student generated: tests, written
assignment, performances, portfolios, artwork, projects, journals, self-assessment, peer-review
Teacher generated: lesson plans, journals, self assessment, peer review
Archived: reports, school records, documents

Methods of Data Collection
Observational Data Field notes, observation records, logs,
narratives, checklists, tally sheets, videotapes, photographs, audiotapes, organizational maps/charts, behavioral scales, time on task analysis
Inquiry Data Interviews, focus groups, conferencing,
surveys, questionnaires, attitude scales

Suggestions for Surveys & Questionnaires
Ensure that survey questions are aligned with research questions
Pilot test the survey
Keep survey brief and to the point
Do not ask questions unrelated to your survey

Triangulation
Multiple forms of data are collected and analyzed
Use at least three ways to look at phenomena to identify themes or characteristics of the situation
