  1. RESEARCH IN MATH EDUCATION COLLECTING DATA

  2. 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?

  3. 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

  4. 2. Getting permission Different type of permission • Institutions or organisations • Specific schools • Participan or a group of participant • Parents of participants

  5. Teachers’ experiences about ICT in their teaching Title The following information is provided to help you decide whether you wish to participate in the present study. (voluntary) You should be aware of that you are free to decide not to participate or to withdraw at any time without affecting your relationship the research. (right to leave) The purpose of this study is to get information about your experiences with ICT in your class (purpose) Data will be collected using a brief survey at the beginning of the study. Then we will observe your classroom-sections at least four times during the second semester. (procedure) Do not hasitate to ask questions about the study before participating or during the study. (right to ask question) I would be happy to share the findings with you after the research is completed. (sharing findings) There are no known risk with this study. If this study is later submitted for publication false names will be used (ethical issues) Please sign this consent form. A copy of this form will be given to you to keep. (right to leave) SignitureDate Prof.Dr. Adnan Baki Researcher KTU

  6. 3. What will I collect? The low of activities in collecting data

  7. 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)

  8. 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
