汇集各方力量强化德育管理

我校是一所初级中学,地处经济比较发达的城乡交界的三元里村.这里属于广州火车站的周边地带,是多个商品的集散地,流动人口多,人员结构复杂,治安问题严峻,整个社会氛围对学校和学生有着不可低估的影响.针对这些复杂情况,几年来,我校积极配合开展创建文明社区活动,努力探索城乡结合部初级中学开展德育工作的路子.经过几年的实践,逐步探索出一些可行的做法,收到良好的效果.     

Examining the relationship between perceptions of teaching self-efficacy,school support and teacher and paraeducator burnout in a residential school setting

Despite teacher self-efficacy and burnout’s influence on student outcomes, little research has been conducted on teacher self-efficacy and burnout in residential treatment schools. This study attempts to fill this need by examining the self-efficacy and burnout of teachers and paraeducators in a residential treatment school in the United States. We explore the relationships between educators’ perceptions of school supports and educators’ sense of self-efficacy and burnout Our results revealed that while educators’ perceptions of school supports were not related to educators’ sense of efficacy, there was a significant relationship between educators’ perceptions of school supports and reported levels of burnout. Educators who reported lower levels of school supports had high levels of burnout. We discuss implications for larger studies on this topic and for supporting educator well-being in residential treatment schools.     

Congruence between Mothers' and Fathers' Differential Treatment of Siblings: Links with Family Relations and Children's Well-Being

We studied patterns of mothers' and fathers' differential treatment of firstborn (average age 10.5 years) and secondborn (average age 8 years) school-age siblings, and we examined the links between parents' differential treatment and children's well-being and dyadic family relationships. Mothers, fathers, and both siblings in 110 families were interviewed in their homes. For each dimension of parental behavior that we assessed (i.e., differential affection and discipline) we created groups of families that reflected mothers' and fathers' levels of differential treatment (e.g., discipline the firstborn more, equal treatment, discipline the secondborn more). Although we detected substantial correspondence between the 2 parents' differential treatment, we found a sizable group of families in which parents' reports were incongruent (i.e., 1 parent reported equal and the other differential treatment). Parental patterns were linked to differences between the siblings' well-being and both sibling and parent-child relationships, with younger siblings exhibiting greater vulnerability to differential treatment. Incongruence in differential warmth was associated with marital distress.     

Functional reading difficulties in Denmark

In this first Danish study of adult reading skills, 1124 adults between 18 and 67 years of age participated in an interview about reading habits and skills, and 445 were tested individually at home using six common texts. Great care was taken to ascertain that subjects were representative of the whole adult population and that the texts covered most types of everyday reading. Three percent of the participants were found to have severe functional reading difficulties and a further 9 percent to have moderate difficulties. Regression analyses found several unique predictors of reading difficulties: age (adults over 45 years reading more poorly than younger adults), limited basic education, no vocational training nor higher education, and a small amount of reading needed at work. The rate of poor readers was about four times higher among persons with low income than among others. Men and women read equally well although men tended to rate themselves lower as readers than women did. Methodological issues and some educational implications are discussed.     

Evaluating and comparing Singaporean and Taiwanese eighth graders’ conceptions of science assessment

Background: Researchers have indicated that assessment practices and methods should support learners’ construction of meaningful understanding of knowledge. Understanding students’ conceptions of assessment will enable us to construct more realistic, valid and fair assessments. Learners’ conceptualization of assessment would be imperative to serve as an essential reference to evaluate their learning progress.

Purpose: This study evaluated and compared the Singaporean and Taiwanese middle school students’ conceptions of science assessment. Within-country gender comparisons were also explored.

Sample: 424 Taiwanese and 333 Singaporean eighth graders were invited for a cross-country comparison.

Design and methods: The participants completed a questionnaire named Conceptions of Science Assessment.

Results: The findings showed that the summative assessment dominates in the Taiwanese classrooms, while formative and summative assessment are usually perceived in Singaporean classrooms. The Singaporean students had a greater tendency than their Taiwanese counterparts to perceive the purpose of assessment as a way of reproducing knowledge, and the formative assessment as improving learning, problem-solving, and critical judgment. No gender differences were found among either the Singaporean or the Taiwanese students.

Conclusions: Educators in both countries should provide learners with more opportunities to experience process-oriented science assessment activities and de-emphasize the usage of examination-oriented practices to achieve the sophistication of conceptions.
