Item Knowledge, perceptions, and attitudes as determinants of youth's intentions to use bioenergy–a cross-national perspective(Taylor & Francis: STM, Behavioural Science and Public Health Titles, 2013-01-01) Halder, P.; Pietarinen, J.; Havu-Nuutinen, S.; Pelkonen, P.; Chang, C. Y.; Prokop, P.; Usak, M.Development of modern bioenergy sector is an important step toward meeting societal demand for reducing CO2 emissions and supplying eco-friendly energy. Young students are the future decision-makers and they will play an important role toward transforming the present fossil fuel driven society into a renewable energy based society. The study aimed to explain young students' intentions to use bioenergy by considering their knowledge perceptions, and attitudes related to bioenergy in Finland, Taiwan, Turkey, and Slovakia. Data for this study came from a previous survey in these countries among 15-year-old 1903 school students. This study with the help of Principal Component Analysis revealed the dimensions of the students' perceptions of and attitudes related to bioenergy. One of the dimensions “pro-environmental intention” was used as the dependent variable in the Multiple Regression Analyses. Results indicated that students' intentions to use bioenergy were mostly guided by their perceptions of the socio-environmental aspects related to bioenergy. Individual level decision-making such as communicating and learning more about bioenergy was also important; however, with a low impact value. Results also suggested that the “critical–environmental” dimension had only minor influence on the students' intentions to use bioenergy. Students' level of bioenergy-knowledge especially those with a relatively higher level appeared to have a strong impact on their intentions to use bioenergy. Young students should be facilitated to become aware of bioenergy in order to influence their intentions to use it in the future.Item A problem-solving based computer-assisted tutorial for the earth sciences(Wiley, 2001-09-01) Chang, C. Y.This study investigated the effects of a Problem-Solving based Computer-Assisted Tutorial (PSCAT) on earth science achievement and attitudes toward earth science of tenth graders (16-year olds) in a senior high school in Taiwan. A total of 137 students who were enrolled in four earth science classes participated in this pre-test/post-test control-group experiment. The experimental groups received the PSCAT; whereas the comparison groups received a Lecture-Internet-Discussion (LID) teaching approach. A multivariate analysis of covariance on the post-test scores of the Earth Science Achievement Test and Attitudes Toward Earth Science Inventory, with students' pre-test scores as the covariates, suggested that PSCAT produced (almost) significantly greater gains on students' earth science achievement than did the LID approach and that no statistically significant increase or decrease in student attitudes toward earth science was found for either group.
