CHAPTER THREE
METHODOLOGY
Introduction
This chapter aims at providing information on the research method adopted for the study. The chapter contained the research design, sample and sample procedure, instrumentation, psychometric properties of the instrument (validity and reliability of the instrument), procedure for data collection, scoring procedure and method of data analysis.
Research Design
The research design adopted for the study is the descriptive survey design method. Daramola (2006) defined descriptive research as a systematic attempt to describe the characteristics of a given population or areas of interest. Descriptive survey involves large sample to ensure meaningful description required empirical evidence through data gathering process and many involves hypothesis testing (Daramola 2006). Descriptive survey method was considered appropriate for this study because the researcher aimed at collecting data and describing the data in a systematic manner. The study is designed to determine and find out the consequences of child abuse on student academic performance as perceived by teachers in secondary schools in Ilorin metropolis.
Population of the Study
The population for the study covers all the teachers in Secondary Schools in Ilorin metropolis.
Sample and Sampling Techniques
The target population for this study consists of Secondary School teachers in Ilorin metropolis, Kwara State. However since everyone cannot participate in the study, random sampling technique was used to select 200 teachers from the secondary schools in the metropolis.
Instrumentation
Instrumentation according to Hassan (1994) is the process of selecting tool which an investigation finds appropriate for the solution of the researchers problem at hand. The main instrumentation for this study is the questionnaire titled “Consequence of Child Abuse on student Academic Performance Questionnaire (CCASAPQ).
According to Opadokun (1997) a questionnaire is a set of relevant questions or statements often used to elicit information (responses) from respondents drawn from the target population of a study. The questionnaire is divided into two sections.
Section A deals with the demographic information while Section B deals with questions or items on consequences of child abuse on students academic performance. The response was scored on four point likert-type rating scale
Strongly Agree (SA) = 4 points
Agree (A) = 3 points
Disagree (D) = 2 points
Strongly Disagree (SD) = 1 point
Psychometric Properties of the Instrument
Validity
The validity of any instrument is the degree to which the instrument measures what it purports to measure. Adewumi and Ogundele (1991) defined validity as the degree to which a test measures what it purports to measure. Therefore, in order to ascertain the validity of the instrument of this study, the draft was submitted to the supervisor and two other experts in the Department of Counselor Education for their useful suggestions in terms of eliminating irrelevant items, modifying some and adding new ones. The final draft was reconstructed and it was adjusted for use in the study. Therefore, both face and content validity of this instrument is thus established.
