Patterns of Instructional-design Factors Prompting Reflective Thinking in Middle-school and College Level Problem-based Learning Environments

Reflective-thinking skills are important in problem-based learning environments as they help learners become deeply engaged in learning. The literature suggests several instructional-design factors (e.g., environment, teaching methods, scaffolding tools) that may prompt reflection in learners. However, it is unclear whether these factors differ based on age or developmental stage. The results of this study indicate that middle-school students perceive the learning environment factor as more important to prompting their thinking, while college students perceive the scaffolding methods factor as more important. While the elements clustered into two factors, most college students disagreed with their helpfulness in prompting reflective thinking, a finding opposite to that obtained for middle-school students. Different patterns were also found between learners’ perceptions of the most helpful elements within each factor. Based on these results, suggestions are given for designing developmentally and age-appropriate PBL learning environments that support reflective thinking.

经济全球化与中国民主政治发展策略

经济全球化是人类社会生存发展的客观趋势，是资本主义生产方式运动的产物。它不仅给世界各国经济的发展提供了前所未有的机遇，同时，也给当代人类社会的诸多领导带来挑战，尤其是对中国民主政治发展的挑战，我国既要面对经济全球化作出新的选择，迎接新的挑战，又要看到我国民主政治发展的新曙光。     

Meshless simulation for skeleton driven elastic deformation

INTRODUCTION Physical simulation is an important area for creating realistic character animations. In the film industry, animators require detailed control of the motion of their characters. Many techniques have been developed for automatically simulating charac- ters’ motion. The skeleton driven elastic deformation is paid much attention in these techniques, since many motions and deformations in character animations are mainly driven by skeleton. In general, however, it is not easy to …     

批判与继承:历史语境中的苏格拉底和海德格尔

批判精神是西方哲学最根本的表现,而对"人"的关怀同样是构成西方哲学的核心之一。这在苏格拉底和海德格尔二人身上表现得尤为明显。然而不可否认的是,在他们共同的思想基底之上横置着一条无形的万里长城:理性和非理性的对立。

Synergetic effect of stannate with o-aminophenol on inhibiting H2 evolution of A1 anode in strong alkaline media

The performance of Al-alloy anode in 4 mol/L KOH with and without stannate and o-aminophenol at 25℃ and 55℃ was studied by hydrogen collection, potentiodynamic polarization and electrochemical impedance spectrum, o-aminophenol acts as a perfect inhibitor because of its adsorbability and forming chelate complex at its optimum concentration of 0.4 mol/L. Stannate enhances the inhibition of o-aminophenol and improves the activity of Al-alloy because of its reduction to tin. There is synergetic effect of stannate with o-aminophenol on the behavior of Al-alloy, and the inhibitive efficiency at 55℃ is better than that at 25 ℃.
