Research approach
Quantitative research is a research method which measures and analyzes the part of a thing which can be quantified to examine researchers’ theoretical hypotheses towards certain things (Saunders, Lewis, & Thornhill, 2007). This study needs to evaluate whether there are differences in students’ cognitive levels towards scientific knowledge before and after interventions, the differences in the levels will be reflected through students’ scores in the questionnaire, thus a quantitative research approach is needed.
Qualitative research is the approach that researchers use to define or deal with a problem. The specific purpose is to thoroughly examine the views of respondents’, so as to further explore the reasons for respondents’ certain actions (Hendricks, 2012). This study focuses on exploring why the education for history of science is so important for science education, by what means and links the education for history of science has a positive impact on students’ learning natural science, which requires an in-depth understanding of the inner thoughts of students, so qualitative research is more suitable for this.
This research will make use of a combination of quantitative and qualitative research approaches, which will help to meet the research objectives, at the same time, the quantitative and qualitative results of this study can verify each other to find whether that are consistent mutually, which can also help to improve the credibility of the study.
Research methods
The quantitative research in this study will use the form of questionnaires. A questionnaire can collect large amounts of data and information in a short period of time, it can also save manpower, material and financial resources, at the same time, the results of questionnaires also facilitate data statistics (Saunders, Lewis, & Thornhill, 2007).
The qualitative research in this study will make use of interviews. Interview is a basic research method that is through a face-to-face interview between interviewers and respondents to understand interviewees’ human psychology and behavior (Saunders, Lewis, & Thornhill, 2007). Interviews are divided into structured interviews, semi-structured interviews and unstructured interviews. A semi-structured interview is between a structured interview and an unstructured interview. In a semi-structured interview, although interviewers control the structure of the interview to a certain extent, respondents are also to express their views and opinions to a large extent (Hendricks, 2012). Semi-structured interviews have the advantages of both structured and unstructured interviews, they can not only avoid the lack of flexibility of structured interviews, as well as the difficulty in making an in-depth discussion, but also avoid the time-consuming, laborious limitations of structured interviews and the difficulty for conducting analysis (Saunders, Lewis, & Thornhill, 2007). Thus this study will use a semi-structured interview.
The successful completion of an interview requires with highly skilled techniques and specially trained interviewers. The author of this study may be inadequate in the interview level, in the interview process, some important information may be omitted due to unskilled recording skills, leading to a lack of enough validity of this interview.
