RESEARCH IN MATH EDUCATION COLLECTING DATA
Collecting Data in Quantitative Research • Who will I study? • What permission will I need? • What information will I collect? • What instrument Will I use? • How will I administer the data collection?
Who will I study? • Population (people, entire group of individuals, schools, institutions) • Sample (representative of population, selected people or school) Quantitative Sampling Strategies Probability Sampling Non-probability Sampling Random Stratified Multy-satage Convenience Snawball Sampling Sampling Cluster Sampling Sampling Sampling
2. Getting permission Different type of permission • Institutions or organisations • Specific schools • Participan or a group of participant • Parents of participants

3. What will I collect? The low of activities in collecting data
4. What instrument will I use? • Locate or develop an instrument • We can develop our own instrument • We can locate and modify someone else’s instrument • We cna chose and use someone else’s instrument Steps for developing an instrument 1. Planning (purpose, content, literature review, open-ended questions, interprete responses, list of objectives, item format) 2. Construction (list of specifications, pool items, expert helps, revise items, copy rough form) 3. Qualitative (rough instrument for first pilot, administer, first pilot, reliability, item analysis, revise instrument, second pilot) 4. Validation (second pilot, item analysis, begin validation, continue validation)
Search for instrument • Look at published jouranl • Look at ERIC search……………. www.askeric.org • Use other websites • Have authors or experts developed the instrument recently • Look at dissertations close to your field 5. How will you adminester the data collection Tools: structured questionnaire, observation Ethical issues
