Beginning teachers’ conceptions of competency: implications to educational policy and teacher education in Malaysia

When any innovations or measurement procedures are introduced into the education system to improve or judge the quality of its teaching force, beginning teachers often have to adapt to these new concepts of what constitute a high quality teaching. This article contends that these new concepts neither necessarily match beginning teachers’ own conceptions about their own competency nor has it given beginning teachers a chance to be heard. This study provides an opportunity for beginning teachers’ ‘voices’ to be heard through phenomenography which is an interpretive research approach to discover what beginning teachers in Malaysia conceive and understand as competence in relation to what they do every day as teachers. The main finding of this study is the key role played by beginning teachers’ conceptions of competency which has provided strong implications for educational policies and teacher education. The findings suggest that teachers need to be represented in any quality improvement measures. Careful attention should also be paid to the school systems and to teacher training programmes to support and encourage teachers in their professional growth as competent teachers.     

数学学科教育眼动研究的应用与启示

国内外的相关研究表明,眼动研究可以通过对数学问题解决过程中的眼动轨迹进行记录以及对注视时间、注视次数等眼动指标的分析,进而了解数学问题解决过程中,大脑的内部加工机制。数学学科能力主要体现为数学问题的解决能力,通过数学学科教育中的眼动研究文献分析发现,眼动研究有助于探寻数学问题解决过程中注意分配及加工策略选择过程。在数学学科教育中针对这些认知加工的特点进行策略教学旨在:培养高效的注意能力、提取关键的表征信息、激发多知识体系的想象力,更好地提高学科教育的有效性。

GLABROUS INFLORESCENCE STEMS regulates trichome branching by genetically interacting with SIM in Arabidopsis

Arabidopsis trichomes are large branched single cells that protrude from the epidermis. The first morphological indication of trichome development is an increase in nuclear content resulting from an initial cycle of endoreduplication. Our previous study has shown that the C2H2 zinc finger protein GLABROUS INFLORESCENCE STEMS (GIS) is required for trichome initiation in the inflorescence organ and for trichome branching in response to gibberellic acid signaling, although GIS gene does not play a direct role in regulating trichome cell division. Here, we describe a novel role of GIS, controlling trichome cell division indirectly by interacting genetically with a key endoreduplication regulator SIAMESE (SIM). Our molecular and genetic studies have shown that GIS might indireclty control cell division and trichome branching by acting downstream of SIM. A loss of function mutation of SIM signficantly reduced the expression of GIS. Futhermore, the overexpression of GIS rescued the trichome cluster cell phenotypes of sim mutant. The gain or loss of function of GIS had no significant effect on the expression of SIM. These results suggest that GIS may play an indirect role in regulating trichome cell division by genetically interacting with SIM.
