Tools of Good Research Identifying a populationIdentifying a population Who/What are we interested in studying: students, parents, teachers, curriculum guides; and in what setting? The population is more narrowly defined than the universe and is influenced by our problem statementWho/What are we interested in studying: students, parents, teachers, curriculum guides; and in what setting?

Tools of Good Research Deciding upon what questions and information to gather and from whomDeciding upon what questions and information to gather and from whom Empirical questions are used to arrive at answers to our research questionsEmpirical questions are used to arrive at answers to our research questions Questions can appear in the form of scales such as attitudinal scales, or they can be open-ended questions that are used in interviews or focus groupsQuestions can appear in the form of scales such as attitudinal scales, or they can be open-ended questions that are used in interviews or focus groups Questions must be reliable and validQuestions must be reliable and valid Consulting with the literature or a jury of experts are two ways of ensuring the reliability and validity of questions.Consulting with the literature or a jury of experts are two ways of ensuring the reliability and validity of questions.

Tools of Good Research Concerns about reliability and validityConcerns about reliability and validity Reliability concerns the extent to which a study, test, questionnaire, or any other measuring procedure yields the same results on repeated trials.Reliability concerns the extent to which a study, test, questionnaire, or any other measuring procedure yields the same results on repeated trials. Validity – the extent to which an indicator of an abstract concept measures what it purports to measure- types of validity- criterion, content, constructValidity – the extent to which an indicator of an abstract concept measures what it purports to measure- types of validity- criterion, content, construct Criterion validity is synonymous with predictive validityCriterion validity is synonymous with predictive validity Content validity implies that the measurement takes into account all the relevant domain of the constructContent validity implies that the measurement takes into account all the relevant domain of the construct Construct validity- does the measure accurately reflects the theoretical concept- if the answer is yes, the measure should relate to other measures that are connected to the theoretical concept.Construct validity- does the measure accurately reflects the theoretical concept- if the answer is yes, the measure should relate to other measures that are connected to the theoretical concept.
