Promoting active student learning in strength of materials with the aid of CAI

The objective of this paper is to discuss how active student learning is possible with the aid of a CAI package for a subject such as Strength of Materials. Multimedia is the latest innovation that can be utilized to improve learning. In this study, multimedia components such as hypertext, sound, graphics, video, and animation are implemented in a CAI package. These capabilities can capture students' attention, and can also illustrate the application of knowledge to real world problems more effectively than traditional teaching methods. The other features of this package include guided examples, theory, and application tests. Guided examples show the students problem solving techniques, and provide feedback according to their responses. The theory and application tests enable the teacher to gauge the students' understanding of the subject matter. Students who do well in the theory test are eligible to attempt the application test, which poses real-world engineering problems. The lesson that can be concluded from this study is that students' problem solving skills can be improved with the aid of CAI which emphasizes anchored instructions. However, to achieve maximum benefit, students also need to possess independent learning skills.     

Study on the distribution of active centers in novel low Ti-loading MgCl2-supported Ziegler-Natta catalyst

Novel MgCl2-supported Ziegler-Natta (Z-N) catalysts prepared using a new one-pot ball milling method caneffectively control the amounts of Ti-loading in the catalysts. Complex GPC data on polypropylene synthesized by thesenovel catalysts were analyzed using the method of fitting the molecular weight distribution (MWD) curves with a multipleFlory-Schulz function. It was found that multiple active centers exist in these novel catalysts. Detailed study of the effects ofthe Ti-loadings in the catalysts on the distribution of the active centers showed that the Ti-loadings in the novelMgCl2-supported Z-N catalysts might affect the proportion of each type of active centers; and might be the main factorresponsible for the effect of the Ti-loadings on the microstructure, the molecular weight and molecular weight distributionwidth of the resultant polymer, the catalytic activity and polymerization kinetics.     

Aligning professional skills and active learning methods: an application for information and communications technology engineering

Engineering education is facing new challenges to effectively provide the appropriate skills to future engineering professionals according to market demands. This study proposes a model based on active learning methods, which is expected to facilitate the acquisition of the professional skills most highly valued in the information and communications technology (ICT) market. The theoretical foundations of the study are based on the specific literature on active learning methodologies. The Delphi method is used to establish the fit between learning methods and generic skills required by the ICT sector. An innovative proposition is therefore presented that groups the required skills in relation to the teaching method that best develops them. The qualitative research suggests that a combination of project-based learning and the learning contract is sufficient to ensure a satisfactory skills level for this profile of engineers.     

促进主动学习(英文)

本文原是1997年10月在南平师专举办的“世行贷款师资发展项目闽、桂、赣英语学科教学法省级研讨班”讲座稿。笔者在提出了讨论观点后,探究了主动学习的概念。根据对一组亚洲学生,特别是对中国学生的研究结果,举出了好学生在学习语言(这里指外语)时选择的手段。为了将教育的主要重点从教师转向学生,笔者认为对那些好学生的反应我们应该谨慎对待,某种学习态度的改变也许会对学习效果产生影响。在这个过程中,笔者没有忘记教师。为此,文章还列举了参加研讨班教师们提出的有关促进主动学习的建议,供大家今后能有效地进行学习者培训作参考。     

Activating the curriculum: a socio-ecological action research frame for health and physical education

The health and physical education (HPE) profession needs to find alternatives to its individualistic and performative focus if it is to remain relevant and meaningful for all learners. This paper presents a way of framing HPE that helps to shift the focus from the individual as autonomous decision-maker, and goes beyond sport and fitness testing as the main contexts for learning. To do this we present the socio-ecological action research (SEAR) frame for unit development that was co-created and enacted over a six-month period involving dialogue between teachers, students, parents, researchers and community. This paper presents findings from semi-structured interviews, student artefacts and field notes collected as one component of a broader three-phase study which spanned three years. The data describe how generalist primary teachers (n=4) from a small Victorian community and their students (aged 8–10 years) tackled a unit of work that positioned centrally the everyday physical experiences of active school travel (AST). Teachers supported students in exploring barriers to their AST, and developing strategies that would counteract some of the negative perceptions that had limited their AST in the past. The findings suggest that the unit of work evolved from an exploration of AST into a much broader exploration of the whole community. This paper does not provide evidence for an alternative way to view HPE, rather it represents an embryonic exploration of how a SEAR frame might support teachers in applying inquiry-based pedagogies that extend beyond the individual as autonomous decision-maker, and promote opportunities for exploration and understanding of environmental, social and personal factors that influence our health and everyday physically active lives. Despite students being positioned as central actors within the SEAR frame, obtaining genuine student voice throughout the process proved challenging.

积极老龄化视域下养教结合的对策研究

提高老年人的生活质量,为其创造健康、参与、安全的最佳机遇,实施积极应对人口老龄化战略,是世界卫生组织提出的重要理念,老年教育是积极应对人口老龄化的重要途径。随着机构养老的不断发展,养老机构将成为老年教育的重要阵地。基于积极老龄化的背景,通过问卷调查和访谈,对养老机构中老年教育的现状进行调研,了解机构中养教结合的情况和老年人的学习需求,分析不同性别、年龄、文化程度、生活水平、职业经历的老年群体参与老年教育的差异,提出建立机制、研发体系、变通方式和特性办学的对策建议,以期为推动老年教育改革与发展提供参考。     

手机颜色词的类型特征及语用功能

"极夜蓝"、"成功银、骑士灰"、神秘紫、"迷幻红"、等这些新出现的手机颜色词是一类值得研究但却没有引起足够关注的新词.从"四个世界"理论出发,有从物理世界、文化世界、心理世界产生的手机颜色词,它们都具有一些特殊的语用功能.
