The investigator must not be confused that research objectives are different from instructional objectives. Through, research and instructional objectives have the same characteristics –SMART- but instructional objectives are expressed in three domains of behavior, namely: cognitive (knowledge), psychomotor (skills) , and affective (values). And the time frame is at the end of the period. If the class is one-hour period, hence, the instructional objectives must be completed within one hour period.
In a research paper, thesis, dissertation, and research project, either a problem or objective is used. It is not advisable to use both problem and objective in research paper, thesis, dissertation and research paper because each problem/objective of the study.
A research objective is defined as statement of purpose for which the investigation is to be conducted.The research objectives are a statement of purpose because this is to guide to be accomplished by the researcher in conducting his research project. Research objectives have the same characteristics, SMART, with research problem.
Similarly, the research objectives are stated specifically in simple language in order that the investigator finds them easy to measure by using research apparatus (i.e., refractometer or salinometer, DO meter thermometer, Ph METER AND OTHERS) or instruments )i.e., questionnaire test, checklist, raiting scale, interview) in gathering data and these data are achieved when correct statistical tools are used to arrive at real results (not maneuvered), but for every activity to
be done , time frame is required because the shorter the completion of the activity, the better.
