This study was an investigation of student beliefs about their EFL education, and it was based upon the subjective task value component of the expectancy-value theory, a prominent theory of achievement motivation. The participants were three cohorts of Japanese public elementary school students (Cohort 1 from 2008; Cohort 2 from 2009; and Cohort 3 from 2010); each cohort consisted of third through sixth graders (N = 1,478; N = 3,693; and N = 1,336, respectively). Three research questions with associated hypotheses were posited in order to determine: (a) if students of all age groups could differentiate the three value components of Enjoyment, Importance, and Use; (b) the degree to which grade levels and genders were different with regard to each value; and (c) if grade level and gender differences were consistent between cohorts. The Young Learners Value Scale (YLVS) was an 11-item, 4-point Likert self report scale created in order to investigate elementary school students' values concerning their EFL education. Prior to conducting inferential analyses on the collected data, the dimensionality, validity, and reliability of the YLVS were established through the use of the Rasch rating-scale model. In addition, the raw scores were converted into interval Rasch measures. Results of the principal components analyses showed that each grade level was able to differentiate the three values of Enjoyment, Importance, and Use. Confirmatory factor analyses showed that the instrument measures as well as the factorial structure of the theoretical model were both invariant across grade level. Results of the two-way ANOVAs indicated that the third grade students valued the Enjoyment, Importance, and Use of English to a statistically significant higher degree than the higher grade levels. Descriptive statistics showed that all grade levels valued the Enjoyment and Importance of English, yet all grade levels responded neutrally to the Use of English. With regard to gender, female students held statistically significant greater values of Enjoyment, Importance, and Use of English and their EFL class than boys, yet these differences were found for only Cohorts 2 and 3. This study was the first, to the best of my knowledge, to use the expectancy-value theory of achievement motivation as a basis for an investigation of public school EFL students. The results indicated that the elementary school students valued the Enjoyment and Importance of English, but were neutral to the Use of English. The integration of more skill-based activities that focus on listening to English and speaking in English to communicate to others and a reduction in fun-focused activities such as songs and games might provide a greater opportunity to enhance the students' value of Use.
