Construct validation of a

the systematic collection and analysis of all relevant information necessary to satisfy the language learning requirements of the students within the context of the particular institutions involved in the learning situation.
". . . it is essential for a language program to have well-defined goals so that the subsequent evaluation instruments can accurately measure the extent to which students have mastered the goals/" |

A number of articles have been published on NA such as those by Basturkmen (1998), Berwick (1989), and West (1994). However, the actual detailed studies on this topic are scarce (e. g., Iwai, Kondo, Lim, Ray, Shimizu, & Brown, 1999; Chaudron, et al., 2005). In Japanese contexts, quiet a few studies have explored variables such as students' bio data, motivation, strategies, learning beliefs, learning styles and preference, and perceived difficulty in learning (Hiromori, 2003; Kikuchi, 2005; Kuwabara, Nakanishi, & Komai, 2005; Robson & Midorikawa, 2001; and Suzuki & Kumazawa, 2006). These instruments were employed to investigate individual differences among student respondents. Especially, teachers can make use of such information to better discern characteristics of their students and subsequently making lessons more satisfying for them by addressing their needs. For instance, if students prefer working in pairs to small groups, teachers can provide more pair-work activities. However, it is often difficult to translate subjective student preferences into course objectives. One instrument that reputedly does this can be found in Busch, Elsea, Gruba, and Johnson (1992). Those authors list nine items in which the expression "need" was included in item description wordings so that respondents could specify the extent of their needs with concision (Busch et. al., 1992, p. 18). Moreover, in 2004 Kusanagi and Kumazawa made an attempt to develop and validate an NA instrument with these features. In their study, a Rasch analysis was conducted assuming that all 75 items were unidimensional. The results indicated that several items were misfitting, and the instrument lacked validity. One of the confounding factors was that many terms had a variety of ambiguous wordings which likely tapped into a number of constructs. Ideally, precise wording which taps into a single construct should be used.To what extent is Version 1 of the GELNA valid based on confirmatory factor analyses?

Version 1 of the GELNA was distributed to the participants in class at the end of the first semester in 2005. The distributors instructed students how to fill out the instrument, explained that the results had no consequences on their grades, and mentioned students could leave if they did not want to complete the questionnaire. However, all the students were cooperative and remained in their seats to fill out their responses. Twenty minutes to complete the instrument was allocated.[ p. 5 ]
