1.6 Definition of Terms

To avoid misleading and to have the same understading between the researcher and the readers, the researcher provides some definition of terms used in this study. The researcher defines some terms as follows. 1.6.1 Perception “Perception is our sensory experience of the world around us. Perception not only creates our experience of the world around us; it allows us to act within our environment” Wagner, 2009. Thus, we can say that perception is the way people see, react, perceive, conceive and comprehend about the environment 7 around them as the result of experiencing something. Huffman, Vernoy, M., and Vernoy, J. in their book Psychology in Action explain when people receive some sensory data, they will always try to organize those data and then interpret it into something that is familiar with their mental pattern 2000: 107. Based on these experts’ explanations, in this study, the writer formulates the definition of perception as someone’s point of view and opinion that heshe obtains from interpreting something about what shehe ever experienced in hisher environtment. For example, in this study the researcher wants to conduct research on students’ perception toward the implementation of portfolio assessment in writing class. In other words, it can be said that the researcher wants to conduct research which investigate the opinion of the students about portfolio assessment that they have ever experienced in their writing class. 1.6.2 Assessment Rayment 2006: 2 describes assessment as a method and process.
