1.0 Introduction

1.1 Background

History of science is the study of the history of the occurrence and development of science, history of science is considered as a very valuable educational resource for science education. Its educational value has been gradually paid a universal attention by educationalists and scientists, education for history of science has become an important strategy of science education (Solomon, Duveen & Scot, 1992). Many studies have confirmed that the conduct of science education will help students with acquiring scientific knowledge, thus affirming the importance of education for history of science. However, there is not a large amount of researches on through what areas the education for history of science influence students’ academic record, such as whether the education for history of science may affect the way of students’ learning thereby affecting students' mastery of scientific knowledge, whether the education for history of science is also likely to affect students' motivation to learn, thereby affecting students' mastery of scientific knowledge and so on. The author of this study believes that the education for history of science is important, but taking the right strategy for the education for history of science is also very important, otherwise the education for history of science may not achieve the intended purpose. Revealing through which links the education for history of science influence students’ academic record helps teachers to take a more targeted and appropriate strategy for education for history of science.科学史是科学的发生和发展史的研究，科学史是科学教育的一个非常宝贵的教育资源。其教育价值日益受到普遍关注的教育家和科学家，为科学史教育已经成为一个重要的科学教育策略（所罗门，杜维恩与苏格兰人，1992）。许多研究已经证实，科学教育的行为将帮助学生获取科学知识，从而肯定了教育的重要性，对科学史。然而，没有大量的研究在什么领域影响学生学习成绩的科学史教育，如是否为科学史教育可能会影响学生的学习从而影响学生科学知识的掌握方式，无论是科学史的教育也可能影响学生的学习动机，进而影响学生科学知识的掌握等。这项研究的作者认为，科学史教育是重要的，但采取正确的策略，对于科学史教育是非常重要的，否则，科学史的教育不可能达到预期的目的。通过这些链接，揭示影响学生学习成绩的科学史教育有助于教师采取更具针对性和科学史教育适当的策略。#p#分页标题#e#

2.0 Literature review

This chapter is mainly through reviewing Solomon, Duveen and Scot’s (1992) and Khalick and Lederman’s (2000) researches to discover the strengths and weaknesses in their researches, so as to tally up the research contents and research methods which are meaningful for the author’s future research.

 

 

In Teaching about the Nature of Science through History: Action Research in the Classroom, Solomon, Duveen and Scot’s (1992) observe and record that through historical studies how learning science may have an impact on students’ understanding of the nature of science, as well as their learning of scientific concepts. This report describes the process of an 18-month action research about observing British pupils’ learning of nature of science. It took some aspects of history of science as the purpose. The action research happened within five classrooms. Practicing teachers who used a set of historical materials which were specially written for this study were involved in this research. Solomon, Duveen and Scot’s (1992) make use of an interviews and a questionnaire for data collection, investigating the differences existing in understanding and perception of scientific and concepts before and after intervening. The investigation results showed that, both types of data collection, questionnaire and interview revealed obviously that the curriculum provision for teaching the history of science contributed valuably to the students’ understanding of the nature of science.

Solomon, Duveen and Scot (1992) were through a survey to find that there were differences in students’ awareness and perception of scientific concepts and knowledge before and after they were intervened, confirming that the teaching of history of science contributed largely to students' understanding of the nature of science. their research designs helped them to achieve the purpose of the study better. The biggest advantage of Solomon, Duveen and Scot’s (1992) research is the use of combination of qualitative research and quantitative research approaches, both the qualitative and quantitative research results were consistent, making the findings have a high degree of reliability and validity. It not only confirms the importance of teaching of the history of science, but also to some extent explains why the teaching of history of science is so important. The disadvantage is that he makes use of an action research method, and as action research methods lack scientific rigor, in an actual research, it might not be able to tightly control the conditions, there might be not enough accuracy, reliability for the research results. For example, Solomon, Duveen and Scot (1992) applied different teachers to different classes, as the teaching styles of different teachers’ were different, some students’ understanding and perception of scientific knowledge and concepts have been improved after the intervention, which might be because they preferred the teaching style of certain, rather than the teaching of history of science.#p#分页标题#e#

Solomon, Duveen and Scot (1992) implemented an action research project. Their research mainly identified the importance of teaching of history of science for science education. In this study, it will be through first-hand data to support his conclusions, and further explore through which links, the teaching of history of science has a positive influence on students’ learning scientific knowledge. This study will also adopt an action research method, like what Solomon, Duveen and Scot (1992) did in their study. This research may also be because of being unable to closely control the conditions, leading to the lack of enough accuracy, reliability. In order to better implement interventions towards students, in this study, it will especially write some historical materials. The criteria for selection of the historical material is, these historical materials should ease of comprehension, fit with syllabus content and what pupils need to learn.

 

 

Khalick and Lederman’s (2000) research discusses the influence of history of science courses on students' views of nature of science. Khalick and Lederman’s (2000) research purpose was to assess the influence of the history of science (HOS) courses on college students' conceptions of nature of science (NOS), it examined whether participants who entered the HOS courses with a conceptual framework consistent with contemporary NOS views acquired more elaborate NOS understandings. In Khalick and Lederman’s (2000) research, the participants were 166 undergraduate and graduate students and 15 preservice secondary science teachers. An open-ended questionnaire was used to assess participants' pre- and post-instruction NOS views. Khalick and Lederman’s (2000) research results showed that HOS courses affected students' NOS views slightly. This finding did not provide empirical support for advocating that HOS course would help with students' NOS views.

 

 

The study implemented research from the perspectives of both teachers and students respectively, it made use of controversy course, evolution course, the survey course, these three courses as a means of intervention, using open-ended questionnaires and semi-structured interview for collecting data, which was a more comprehensive study of the impact of the teaching of history of science, the entire research design of Khalick and Lederman’s (2000) study was valid for meeting the research questions. History of science teaching contains many contents, to fully investigate the impact of teaching for history of science, it must first of all determines the contents of history of science teaching. Contents of history of science teaching used in this study were divided into three parts: controversy course, evolution course, the survey course. These three courses represent the main contents of history of science teaching today, Khalick and Lederman (2000) investigated the impact of these three courses, which could reflect the impact of history of science teaching more comprehensively. This is one of the strengths of this study. Khalick and Lederman’s (2000) research reveals that it should make sure the contents of history of science teaching, making use of controversy course, evolution course, the survey course as a means of intervention, which can better reflect the influence of history of science teaching. Khalick and Lederman’s (2000) study puts forward the view that history of science education does not have a positive impact on students’ science education. Their data were from open-ended questionnaires and semi-structured interviews, data collected from both research methods were not conducive to quantitative analysis. At the same time, it failed to use attitude scale to measure changes in respondents’ views before and after intervention, it just asked the respondents to state their subjective feelings. Therefore, the author believes that the biggest drawback of this research lies in a lack of quantitative data to support conclusions.#p#分页标题#e#

 

 

Khalick and Lederman’s (2000) study is an action research project. Their research identified the importance of three main history of science teaching courses for science education. In this study, it will be through first-hand data to confirm or disprove their conclusions, then further explore through which links, history of science teaching has positive impact on students’ learning of scientific knowledge. Like what Khalick and Lederman (2000) did in their study, in this study, it will also use a semi-structured interview, but interview has the disadvantage of consuming more time, manpower and material resources. As an interview is costly, time-consuming, it is difficult to carry out with a large-scale, the sample size will be small, resulting in a lack of enough representativeness of the interview. In order to better implement interventions towards students, this study will take controversy course, evolution course, the survey course as a means of intervention, which can better reflect the influence of history of science teaching.

 

 

This study will be based on the research contents and methods of Solomon, Duveen and Scot’s (1992) and Khalick and Lederman’s (2000) studies, specific research steps will be presented in next chapter.

 

 

3.0 Methodology

3.1 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.#p#分页标题#e#

 

 

3.2 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.

 

 

3.3 Research design

The research objects of this study will be 50 8-12 years old pupils, all students will attend the same history of science causes and are required to complete the same assignments. The science history course is divided into three types, courses of each type will be offered two times a week and last a total of 5 weeks. Contents of courses of the three types will refer to Khalick and Lederman’s (2000) research, specific contents are described as follows. The first course is entitled as controversy course. It focuses on accounts of controversial scientific discoveries. The course aims to strengthen the rational, social and psychological characteristics that have typed the meaning and methods of the natural sciences. The second course is survey course, it focuses on the interaction of scientific ideas with their social and cultural contexts. The third course is evolution course, from its inception to the present, the course discusses the reception and history of evolution theory.#p#分页标题#e#

 

 

This study will invite teachers with rich experience in teaching to be responsible for history of science teaching, the researcher will collaborate with the teachers to participate in the teaching of history of science. The researcher will be primarily responsible for recording the behavior, language, learning attitude and all other relevant details of students in the classrooms. After class, the researcher will discuss with the teachers to adjust the teaching content and teaching methods.

 

 

In the beginning and at the end of all courses, a questionnaire and an interview will be carried out towards the students. The questionnaires will be distributed and taken back through an on-site form. The questionnaire aims at investigating students' views towards natural science knowledge, motivation for learning natural science and learning styles for natural science. Answers of the questions in the questionnaire will be expressed by using Likert scale (1= least agreement to 5= most agreement). The specific content of the questionnaire is shown in Appendix 1. The interview will be carried out by using a semi-structured interview, the interview of each time will last about 30 minutes. The interview objects will be nine randomly drawing students. The interview aims at investigating the students' views towards natural science knowledge, motivation for learning natural science and learning styles of natural science, as well as their psychology and views for learning of natural sciences. The interview outline is shown in Appendix 2.

 

 

3.4 Data analysis

Data analysis of the questionnaire will be mainly through comparing whether there are differences in students’ scores the before and after the interventions, so as to understand whether history of science courses had an impact on them. Analysis of the interview will be mainly by comparing whether there are differences in students’ psychology, cognition and motivation towards scientific knowledge learning before and after interventions, so as to understand through which links what history of science course affects students.

 

 

3.5 Reliability and validity

The reliability test of the questionnaire is mainly through using inter-item consistency method. By using SPSS 16.0 to calculate Cronbach's α, if α> 0.7 the reliability of the questionnaire is satisfactory. Relevant experts and scholars will be invited to test the content validity of the questionnaire, if the Content Validity Index (CVI) is greater than 0.7, the content validity will be qualified (Nunnally & Bernstein, 1994).

In order to ensure the reliability and validity of analysis of the interview data, first of all, the interview content will be recorded and taken down, which facilitates subsequent verification towards the data and information. Then, the process of data processing will strictly follow Yin’s (2011) steps, ensuring that valuable data and information can be processed via a complete and accurate analysis. Firstly, it will design coding table. Secondly, all information collected in the interview will be compiled, classified and organized into a textual form. Thirdly, it will be according to the coding table to sort out the data.#p#分页标题#e#
