6. 6 3. What will I collect? The low of activities in collecting data Flow of Activities Example Identify the variable Operationally define the variable Locate data (measures, observations, questionnaires) Collect data about instruments yielding numeric score Self-efficacy for learning from LO Level of confidence that an individual can learn something by using LO Attitude scale on computer use and ICT (Likert scale) Scores of each item ranged from 0 to 10 “8 to 10” completely confident

7. 7 4. What instrument will I use? Locate or develop an instrument Locate or develop an instrument 1. We can develop our own instrument 2. We can locate and modify someone else’s instrument 3. 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)
