This opening article of the Special Issue makes an argument for parallel definitions of scientific literacy and mathematical literacy that have shared features: importance of general cognitive and metacognitive abilities and reasoning/thinking and discipline-specific language, habits-of-mind/emotional dispositions, and information communication technology strategies to prepare people for adult life and democratic citizenship. These frameworks provide potential insights into research and pedagogy. Furthermore, they provide guidelines for second-generation standards, curriculum development and assessment so as not to overlook or underemphasize the fundamental literacy component of mathematical and scientific literacy for all students, which can result in fuller participation in the public debate about science, mathematics, technology, society, and environment issues.

The purpose of this study was to investigate 8th graders with different learning styles their motivation outcomes after implementing 10 weeks (40 hours) inquiry-based teaching. Two hundreds and fifty four 8th graders were involved in experimental group, this group of students experienced inquiry instruction. Two hundreds and thirty two 8th graders were involved in control group, they were taught by traditional science teaching. Students' motivation toward science learning questionnaire (SMTSL) (Tuan, Chin & Shieh, 2005) were implemented in both groups in the beginning and at the end of the study. Students in the experimental group filled out learning preference questionnaire (Lumsdaine & Lumsdaine, 1995) in the beginning of the study. Forty students which represent different learning styles were chosen from five experimental classes to conduct post-test interview. Paired t-test, MANOVA, analytic inductive methods were used for analyzing both qualitative and quantitative data. Findings indicated that after inquiry instruction students' motivation increased significantly (p < .001) than students who enrolled in traditional teaching. Four different learning styles of students increased significantly (p < .005) in SMTSL scales: self-efficacy, active learning strategies, science learning value, performance goal and achievement goal. No significant difference was found among four learning styles of students' motivation after inquiry teaching. Interview data supported that most of students with different learning styles were willing to participate in the inquiry learning activities, while they hold different reasons for their engagement. Findings confirm inquiry-based science teaching can motivate students with different learning styles in science learning.

The purposes of this study are: to apply the ARCS model in designing an acid and bases unit, and to assess a single class of 11th graders for motivation and achievement outcomes before and after ARCS instruction. Four essential strategies for designing motivation instruction in the ARCS model were: Attention, Relevance, Confidence, and Satisfaction. We used the ARCS model in designing a 10-hour acids and bases lesson for one class of 11th graders with low interest and motivation in chemistry learning. Both the Students' Motivation toward Science Learning questionnaire (SMTSL) (Tuan, Chin & Shieh, in press) and a teacher-designed achievement test were implemented before and after instruction. In addition, students' self-reporting on time engagement in learning before and during the instruction was also collected. The results of the study indicated that both students' motivation and achievement in the acids and bases unit increased significantly (p < 0.05) after the ARCS instruction. Students' time engagement during the ARCS lessons had increased from before. Findings of the study showed that using the ARCS model to teach acids and bases unit could improve low motivated students' level of motivation and achievement. The implications for chemistry teaching will be discussed in the paper.
