Empowerment and relationships: A classroom model to enhance student motivation

This project focused on the goal of establishing a classroom model of motivation in which the source of student motivation is based on internal mechanisms or structures, along with the establishment of greater self-regulatory opportunities for students, and which results in greater student empowerment and motivation. One-hundred current elementary and secondary teachers and 100 university preservice teacher education students completed a 40-item Likert-type questionnaire that focused on four classroom dimensions of affirmation, rejection, student empowerment and teacher control. The results of this project suggested that, although veteran and preservice teachers agreed on the need for teacher control in the classroom, there was less agreement about their perceptions of the need to create a classroom environment of positive affirmation and student empowerment. Implications for future research and the need for creating an affirming, empowering, motivational classroom environment are discussed in light of the limitations for teachers and schools to encourage these constructs associated with recent federal legislative policies.     

Experiential learning in doctoral training programmes: fostering personal epistemology through collaboration

There has been increasing recognition for the need to reform doctoral training practices to foster students’ personal epistemology. This study describes the design and evaluation of a learning experience designed to help students understand the scholarly publication process. Firstly, this study discusses the design of the learning experience, describing the collaborative process of writing an interdisciplinary publication using both online and face-to-face learning. Secondly, this study evaluates the effectiveness of the learning experience by examining students’ reflections. We show that participation in the learning experience helped students to develop their academic writing proficiency, collaboration and teamwork, intercultural competence, and ability to engage in reflective practice. Importantly, we show that each student also created more individualised knowledge, gaining insight into how they and others think. This study, therefore, demonstrates that personal epistemology can be fostered through collaboration in a doctoral writing group context.

锦州市市区交通干线周边土壤及植物体中铅污染状况的研究

以锦州市交通要道两旁的土壤以及银杏树叶为研究对象,采集土壤以及对应的植物样品60份,背景土壤及植物样品10份。利用火焰原子吸收分光光度法分别测定植物样品以及土壤样品中铅的含量,得到锦州市市区土壤中Pb的平均含量为58.0738mg/kg,银杏叶片中Pb的平均含量为4.7206mg/kg。采用Muller地积指数法进行土壤Pb污染评价,土壤污染程度为无污染-轻度污染级别。银杏叶对土壤中Pb富集系数普遍较低。
