have reflection on their speaking aspects namely comprehension, vocabulary, fluency, pronunciation,
and structure.
3.9. Reliability
1. Reliability of Observation The Reliability of this observation was its consistency so that its data was
trustworthy Setiyadi, 2006:30. Based on the way of collecting data, the researcher used triangulation by using questionaire. It was used to get
consistent data during the research. The construction of its item was in the same way of constructing questionnaire that was in form of CALLA’s
aspects and LLSQ.

Self-Plan 1 - 9
Self-Monitor 10 – 14
Self-Evaluation 15– 19
Self Expansion 20 - 24
2. Reliability of Questionnaire The reliability of questionnaire was tested by using Cronbach’s Alfa.
Cronbach’s alpha coefficients were computed for the entire set of 4 different categories in 24 items α = .774 in order to find out the internal

consistency reliability of learning strategies questionnaire. Since the category of α = .774 is reliable then the questionnaire can be used and the
result can yield reliable information. It was translated to Bahasa Indonesia in order to facilitate the students in understanding the statement. Those
statements were measured under five categories i.e. self-plan, self-monitor, self-evaluation, and self-expansion.

2. Reliability of Speaking Test
Reliability of the test can be defined as the extent to which a test produces consistent result Setiyadi, 2006:16. The researcher used inter-rater to see the
reliability of the raters in determining the speaking skill that the student has before and after the training. In order to see the coefficient of the reliability,
the researcher employed the formula of coefficient correlation. It was found that the result of rk= 1 which means the score given by the raters test fulfilled
the criteria of reliability to support the data before and after process of the training.
