11: Validity and Reliability & Ethical Considerations

-

Hi and assalamualaikum,

The semester is getting nearer to the end now and for this week’s task, I am going to update about validity and reliability of the research instrument and also some ethical considerations regarding data collection procedure. These two elements are very important for a research and should be taken seriously.


Validity and Reliability

Validity is the degree to which any measuring instrument measures what it is intended to measure (Thatcher, 2010) while reliability refers to the “consistency of the measure” (Heale & Twycross, 2015). Reliability signifies the consistency, stability and repeatability of results. Therefore, the finding is regarded as reliable if consistent results have been acquired in similar situations but different circumstances (Twycross and Shields, 2004).

As cited in Mohajan (2017), both of these concepts of validity and reliability are important to improve the accuracy of the assessment and evaluation of a research study (Tavakol & Dennick, 2011). Hence, it can be concluded that a good research instrument should possess these two qualities which are being valid and reliable.


Ethical Considerations

A study by Arifin (2018) highlighted some ethical issues that need to be considered when conducting a research. The issues are informed consent from the participants, anonymity and confidentiality (Arifin, 2018).

:. When conducting my research I will ensure that my instruments are both valid and reliable to be employed. I would ask for experts’ opinions to validate my questionnaires and conduct pilot study to ensure reliability of my instruments. Regarding ethical considerations, I will ensure to obtain informed consent from the respondents and their identity and answers will remain anonymous and confidential.

15: Review Chapter One, Two and Three

Greetings! At this point, I am more than halfway there towards completing my research proposal so for this entry, I would like to look back on all the progress that I have done so far regarding the three chapters and the study as a whole.   There are some amendments that I have decided to make concerning my study. I have considered to change my working title from ‘LEARNING STYLES AND STRATEGIES IN LEARNING LITERATURE AMONG PRE-SERVICE ESL TEACHERS’ to ‘LEARNING STYLES AND STRATEGIES IN LEARNING LITERATURE OF SUCCESSFUL AND LESS SUCCESSFUL TESL UNDERGRADUATE STUDENTS ’. They are both pretty much the same but I would like to emphasise more on the successful and less successful learners in my study. Chapter One :. I still need to find some previous researches to support my sub-sections: 1.2 Background of Study and 1.3 Problem Statement. Chapter Two :. Literature review is the most challenging out of the three chapters since it requires a lot of reading and I still have mo

09: Research Population and Sample

Hello and a very good morning! This week’s topic is about deciding the research population and sample for my study. According to Bacon-Shonne (2015) , population is the respondents of interest of the researcher and sample is the respondents selected from the population for a study. My desired target respondents would be all TESL undergraduate students from a public university in Malaysia. In choosing my respondents, I need to ensure that they are currently taking or have already taken literature subjects in their university due to the focus of my study which is learning literature. I also need to know their academic performance in literature subjects to determine whether they are successful or less successful learners. I have not decided yet on which university should I choose but I am thinking of selecting respondents from UiTM Puncak Alam since it is closer to Shah Alam. Hence, it will be easier for me to go and meet the respondents to conduct my study. The sampling technique tha
