Chapter 3 details the research methodologies employed in the study, including research design, sampling technique, and data gathering procedures. The study will focus on seventh graders from section Sampaguita in Magdalena, utilizing purposive sampling to gather data through questionnaires. Statistical treatments will be applied to analyze responses, including the use of weighted mean and standard deviation for data interpretation.

3. Research Design
One basic rule holds that an avenue to the approach of truth is
the employment of the experimental and descriptive design with
intense accuracy to surface out the meaningful aspects of the data
from those phenomena observed during the process of the
investigation. An experiment is a study in which a treatment,
procedure, or program is intentionally introduced and a result or
outcome are observed and compared. Thus, the term descriptive
describes the essential character of the method.

4. Respondents of the Study
The respondents of the study will come from the district of
Magdalena, the seventh graders specifically section Sampaguita of
the said school will be the center of the study.

5. Sampling Technique
Purposive sampling will be employed in this study among (30) thirty seventh
graders in Magdalena National High school hence they will be purposely selected as the
actual respondents during the day set for the gathering and retrieving of data from them.
As claimed by Van (2023), purposive is etymologically derived from an old French
word, “purposer” which denotes purpose. As applied to educational research, once
something is set up with intention, it has a purpose as a resolute determination to gather
data from the target respondents and thus assure the validity and reliability of information
shared by them.

6. Research Procedure
As there is assurance for validity and reliability of the major instrument coupled with the
approval by the thesis adviser to conduct an actual study, letters addressed to the principal of selected
school in Magdalena district in Laguna will be prepared, requesting permission to distribute two sets of
questionnaire to seventh graders as actual respondents of this study.
As approval is granted by the said school authorities, the distribution and retrieval of the
aforementioned two sets of major instrument will be done personally by the researcher in order to clarify
questions which will be found highly technical in nature by the actual respondents.

7. Research Instrument
Two sets of activity and questionnaire will be issued to the actual
respondents of this study. The items in the said questionnaires will be
based on the basic problems advanced in this study for objectivity,
relevance and suitability to the problem areas investigated, as well as
probability of favorable reception and return from the said respondents.

8. Statistical Treatment
The responses of the control group of respondents will be tallied and tabulated in
order to determine the frequencies and equivalent percentages as basis for the
application of the formulas.
Weighted mean formula which is designed to solve the centrality as basis for the
weight of the responses for sub problems 1, 2 and 3.
Standard deviation formula designed to know the variability or dispersion of data
around the mean.
