Teachers’ perception of mobile edutainment for special needs learners: the Malaysian case

Study of Malaysian adoption of mobile learning (m-learning) is still in the early stages. However, there are numerous researchers in the country exploring the potential and application of m-learning in the Malaysian education system, including special education. A key question is whether teachers are prepared to incorporate mobile technology as part of their teaching tools or do teachers perceive mobile technology only as personal communication gadgets. This paper investigates teachers' perception of m-learning applications in special education classes. Interviews were conducted to collect related information on teachers' perceptions of m-learning in the selected schools. The teachers expressed that there are limited resources to cater to the attention of special needs learners and they believed edutainment technologies such as augmented reality, game-based educational software and animation projects could be the answer. The benefits and challenges of implementing blended learning for special education are also discussed. The paper concludes by summarising the current environment of m-learning in Malaysian special needs education, together with recommendations for future use of the technology.     

Opportunity to learn and student engagement: a HLM study on eighth grade science achievement

This study examined the individual, class, and school level variability of the students’ science achievement. It was hypothesized that there are school or teacher effects which contribute toward explaining achievement differences, besides the student level differences. Owing to the nested structure of the data in Trends in International Mathematics and Science Study, we used the Hierarchical Linear Modeling methodology. Besides the significant effect of engagement, the teachers’ teaching certification in science and the topic coverage were both significant factors as were the effect of school SES and availability of remedial and enrichment programs in science. The study makes a contribution to a better understanding of the opportunity to learn variables at classroom and school level in students’ science achievement.

Q55OD高强板断口分离缺陷的微观分析

Q550D高强板在进行室温拉伸试验后,断口出现分离缺陷。通过扫描电镜、金相显微镜、透射电镜对其断口及分离面的微观形貌、分离裂纹末端及远离裂纹的断口横截面组织及亚结构等进行了观察分析。结果表明：拉伸变形前,组织为贝氏体＋碳化物,部分晶界及碳化物周围有位错塞积,但不存在裂纹。拉伸变形时,贝氏体晶界及亚晶界呈链状分布的大尺寸渗碳体颗粒附近的位错塞积引起应力集中,形成微裂纹及孔洞;同时,拉伸断口的颈缩变形引起垂直于拉伸轴方向产生新的拉应力,导致微裂纹及孔洞在拉伸轴方向优先扩展形成裂纹;这两者成为产生分离缺陷的主要原因。分离裂纹的长度与裂纹扩展时的应力状态及组织变形程度有关。
