Developing students' positive attitude toward learning is one of the important things, because some researchers mention that attitudes toward the subjects are related to academic achievement. Teachers, in the implementation of learning can evaluate attitudes toward the subjects, in order to know how students' attitude toward learning that is/has been going on. Therefore, an attitude assessment is required for valid, reliable and practical learning. The purpose of this research is to develop a Likert scale type questionnaire that can measure students' attitudes toward chemistry. In this study initially has been compiled as many as 43 items. The items in the present scale were adapted from the Test of Science-Related Attitudes (TOSRA) and Attitudes towards Chemistry Lessons Scale (ATCLS). After the contents validation of the questionnaire by the expert, the questionnaire is tested on 245 college students. Determination of construct validity which is conducted with exploratory factor analysis obtained 32 items valid question. The result of factor analysis shows that the scale has nine factors that explain 62.105% of the total variance. In addition, it shows the finding of 'reliability coefficient (Cronbach's alpha) of 0.91. The results obtained showed that it has obtained valid and reliable questionnaires as a measuring tool that can be used to determine student attitudes toward chemistry in chemistry foodstuffs lectures. more...

This study was aimed to figure out: (1) the implementation of contextual learning approaches; (2) the learning outcome of conservation education using contextual approach on the internship program preparation class; (3) the conservation-based behaviour of the internship program participants; (4) the contribution of conservation education results using contextual approach on the internship program preparation class to the conservation-based behaviour of the participants. The study was conducted at Mechanical Engineering program, Engineering Faculty, UNNES and industries in Central Java in 2016. The implementation of contextual learning approach data were gathered using direct observation. The learning outcome of the conservation education implementation using contextual approach to the internship program preparation class were gathered using a test sheet and the data of conservation-based behaviour of the internship program participants were gathered using the observation sheet. The data were analysed using descriptive and simple regression. This study showed that: (1) the implementation of contextual learning approach carried out at the internship program preparation class was in the form of additional material on the conservation education course; (2) the learning outcome of the conservation education with contextual approach were mostly higher; (3) the conservation-based behaviour of the internship program participants was mostly higher; (4) the contribution of learning outcome of the conservation education carried out using a contextual approach to the internship program preparation class was 0.98 to the conservation-based behaviour of the internship program participants in the Mechanical Engineering program, Engineering Faculty, UNNES. more...
