F. Trustworthiness
The goal of trustworthiness is to support the argument that the inquiry’s
finding are “worth paying attention to” Lincoln Guba, 1985, p. 290. Before ensuring the trustworthiness of the result of the analysis, I need to ensure that the
data gathered were trustworthy as well. The trustworthiness of the data in this study was supported by two factors.
First, the data gathered from the participants who met the criteria of this study. They were second-year students, had high level of motivation and experienced
CA and FNE. Second, the instruments employed in this study were valid and reliable. Validity and reliability of the FLCAS and WPI have been proved by
previous studies as it is a well-known questionnaire used in the research of this area. According to Horwitz 1986, pilot testing of the scale with seventy-five
introductory Spanish students at the University of Texas at Austin demonstrated reliability and validity of FLCAS. In terms of internal reliability, the FLCAS
achieving an alpha coefficient of .93 with all items producing significant corrected item-total scale correlations. Test-retest reliability over eight weeks yielded an r=
.83 p.001. Amabile et al. 1994 reported that WPI has meaningful factor structures, adequate internal consistency, good short-term test-retest reliability and
good longer term stability. To maintain the construct and content validity of the interview guideline, the interview questions were reviewed by two graduate
students of ELS at Sanata Dharma University. The trustworthiness of the result of analysis was achieved by doing member
checking. Member checking allowed for further elaboration of questions answered or omissions of any information collected. After the themes were established, they
52 were sent back to two participants who read the summarized phrases and themes.
These two individuals read the documentation and concurred with the results. They agreed that the information presented to them was true and accurate to the
best of their knowledge. By following this model, the resulting conclusions were considered validated.
