METHODOLOGY

This chapter explains the research design, the locale of the study, the respondents

of the study, the general procedure, the instruments that will be utilized, the data

gathering procedure and the statistical treatment that will be employed by the researchers.

Research Design

The research design of the study is the blueprint and the system that will address

the research issue effectively that is presented in Figure 2. The researchers will use the

descriptive-survey method of research in conducting the study. The participants will

answer questions administered through survey questionnaires. The responses given will

be tallied and described by the researchers. Then, the researchers will determine the

dominant factor and to describe any variations among and between the factors affecting

the strand choice of the male and female senior high school students of Notre Dame of

Dadiangas University. It is descriptive-survey in a sense that the data that will be

gathered using the survey questionnaire shall be analyzed and described.

Validated questionnaires would be use and it is under descriptive design. These

requires gathering of information that needs sufficient and accurate answers from the

respondents towards the questions given by the researchers. This technique was used to

gather data and presented.

Locale of the Study

The study was conducted at Notre Dame of Dadiangas University – Integrated

Basic Education Department Senior High School Department Marist Avenue, General

Santos City, South Cotabato, Philippines. The school is a Catholic institution run by the

Marist Brother or FMS (Frates Maristaѐ a Scholis) of the school. It is ISO 9001:2015

certified. It offers Academic tract with three strands in Senior High School which are

STEM, ABM, and HUMSS.

Respondents of the Study

The sample size were determined using the Slovin’s Formula. The respondents

were chosen by using random sampling technique. The researchers selected random

Grade 11 students coming from the different strands of Notre Dame of the Dadiangas

University Senior High School Department enrolled in S.Y. 2019 - 2020 as their

respondents. The total respondents of the study is 302.

Research Instruments

For the assessment of this study, the researchers will use a validated

questionnaire. The instrument aims to determine the sex and the chosen strand of the

students. It also aims to identify the highest rated factor in choosing a strand of the

students and is composed of four items which discuss the four important variables in

choosing a strand: Childhood Aspiration, Family, Peers, and Personality. The 5-point

Likert scale that the researcher will use is adapted from the study of Mehr & Omran

(2013).

Statistical Treatment

To analyze the data, the following statistical tools will be used: Frequency count

and percentage; to determine the actual number of male and female students and the

strand who will answer in the various factors affecting the Grade 11 students in choosing

strand. Mean and weighted mean; to determine the highest rated factor using the Data

Interpretation, z-test for the difference between sex and; lastly, the researcher will use

One-way Analysis of Variance (ANOVA) to determine if there is a significant difference

between the dominant factor and the sex and strand choice of the researcher’s

respondents.

Weighted Formula
Weighted mean = Σwx/Σw
Σ = the sum of (in other words…add them up!).
w = the weights.
x = the value.

General Procedure

The researchers will make a letter of request and will submit it to the Assistant

Principal to ask permission to conduct their study within the premises of Notre Dame of

Dadiangas University, Main Campus. The researchers also make a Letter of Approval for

the researchers validators. After the approval, the self-made questionnaires will be

validated by the researchers’ grammarian and statistician.

Second, in order to acquire the overall population of Grade 11 students which

enrolled in S.Y. 2019 – 2020, the researcher will write a letter of request the class list of

Grade 11 students coming from all the different strands to the School Registrar.

Third, to identify the sample size of the respondents that are needed for the study,

the researcher’s will used the Slovin’s formula. After that, the researcher will used

random sampling technique in order to acquire the number of students in the study in all

different strands and use systematic fish bowl method to determine the students that will

be the final respondents of the study.

Fourth, the researcher will ask permission through letter to the teachers and

respondents to conduct the study and allow the selected students to be the respondents.

Fifth, upon the approval, it will serve as the proof that the questionnaires to the

respondents were all set for distribution among respondents. Each student in Grade 11

will be given a questionnaire. The respondents will be oriented about their role on the

study and asked to answer honestly to the following questions. The research

questionnaire will seek out to find the highest rated factor that affects the Grade 11

students in choosing their strand.
