本研究以建构主义为研究哲学基础，提出假设知识主张。建构主义是一种方法，其中“在这些作品中确定的假设认为，个人寻求对他们生活和工作的世界的理解。”他们发展他们经验的主观意义——指向特定对象或事物的意义。这些意义是多种多样的和多个,主要研究者寻找复杂的观点而不是缩小的含义分为几类或想法”(Cresswell, 2003年,p . 8)。这种形式的研究的目标是不确定模式探索社交媒体的方式招募参与者可能是一个有效的工具。包括参与者的观点，并对其进行批判性分析，以理解情况的含义，在本例中，即理解参与者如何看待社交媒体，或参与者如何看待EPA的志愿者活动。国际学生的意见和当地学生的意见都是在其产生的社会背景下进行分析的，这有助于更好地了解未来EPA的战略。
The chapter discusses the research methodology and methods adopted for the research. Three key elements that are required to develop a research framework are the philosophical assumptions of the research, the general procedures of the research and the details procedures of research. The philosophical assumptions made in the research are the knowledge claims made in the research. The general procedures can be termed as the strategies that are being used for enquiry and the detailed procedures are the methods of the research (Cresswell, 2003). The mixed research methodology is adopted for this research and primary data collection is done.
The research philosophy based on which assumption knowledge claims are made in this research is constructivism. Constructivism is an approach where “Assumptions identified in these works hold that individuals seek understanding of the world in which they live and work. They develop subjective meanings of their experiences-meanings directed toward certain objects or things. These meanings are varied and multiple, and leading the researcher to look for the complexity of views rather than narrowing meanings into a few categories or ideas” (Cresswell, 2003, p. 8). The goal of this form of a research is to not identify patterns but to explore ways in which social media could be an effective tool for recruiting participants. The participant views are included and are critically analyzed to understand the meaning of the situation, which in this case is to understand how social media is perceived by participant, or how the volunteer activity with EPA is perceived by the participant. Both international student opinion and local student opinions are analyzed within the social context in which they are created and this enables better insight for futuristic EPA strategies.
The mixed research methodology makes use of both qualitative and quantitative research methods. Qualitative research methods are those attempt to answer the ‘why’ or ‘how’ or ‘when’ aspects of a phenomenon or situation under consideration. For instance, in this research, the researcher wants to know what would motivate people towards participating for volunteer activities at EAP, this is one which is nor measured as a variable, but needs to be answered in participants own words, an expression of their attitude, personal feelings or more. The research process is typically flexible and the researcher would be make knowledge claims based on constructivist perspective. The meanings or solutions being constructed towards proving a hypothesis or solving a problem would be collected in context of a phenomenon where the participant and even the researcher is an actor. The quantitative method is one where the aspects of a phenomenon such as ‘how many’ (Cresswell, 2003). For instance, in this research we wanted to know how many participants make use of social media, this would be a numerical value; similarly, the occurrence of social media usage would also be a numerical value. Where the qualitative method aims at collecting participant meaning and bringing personal value into the research, the quantitative research aims to identify variables for study and analyses the variables towards proving a hypothesis. Measurement and observation in numerical methods play a significant role here. This research takes a combinatory role. The mixed research method has been used here where both qualitative and quantitative style data are collected and hence the stages of enquiry would also vary between quantitative and quantitative research practices.
