贴近学生的真实阅读:国外阅读评价分析——以PIRLS、PISA和NEAP为例

对国外阅读评价的研究有利于我国阅读评价的改进。通过对PIRLS、PISA和NEAP的阅读评价分析可见,要开展有效的阅读评价,首先要确定"以读者为中心"的阅读理念,明晰核心概念内涵;其次,要基于学生的日常阅读,设计科学合理的评价阅读框架,对阅读情境、阅读文本及阅读认知过程进行明确界定;再次,在具体阅读评价实施中,要根据学生的阅读特点合理地编制试题、制定评分标准、开展问卷调查。

Professional ideology and physicians’ perceived disclosure patterns toward cancer patients

This study examined differences in physicians’ perceptions of their disclosure patterns toward cancer patients based on their professional ideological orientation. Adapting Strauss et al.’s (1964) sociotherapeutic (SCT) and somatotherapeutic (SMT) ideologies, it was hypothesized that physicians who strongly identified with the SCT ideology would perceive themselves as more willing to disclose the diagnosis to cancer patients and that there would be differences in the way and types of information presented depending on physicians’ ideological orientation. The findings suggest that physicians perceive choosing particular disclosure patterns based, in part, on their professional ideological orientations. Those who identify with a strong SCT orientation perceive themselves as more willing to disclose the diagnosis and provide some additional information to cancer patients and their families. Implications of these findings and directions for future research are discussed.     

Supporting Teachers on Science‐focused School Trips: Towards an integrated framework of theory and practice

Although science centres and museums are important educational resources, school trips to these places are not often conducted in a manner that could maximise learning. In addressing this issue, a Framework for Museum Practice (FMP) is proposed, derived from the perspectives of Cultural Historical Activity Theory, theories of intrinsic motivation, and research into conceptual learning. It is hypothesised that this theoretically derived framework, if implemented by museum educators, can potentially lead to the creation of resources for teachers that would enable them to make better use of the learning opportunities afforded by school trips, and to maximise the impact on pupil learning, including their affective experience. This paper also describes how the framework was used to guide the development of resources to be used in conjunction with a science museum trip. The resources were tested by two primary school teachers and their classes, and the data were analysed for evidence of teacher and student behaviour consistent with the design principles in the FMP. Findings lend some empirical support for the FMP and suggest that it may offer a guide for the development of museum‐provided resources, which would have the potential to improve the utilisation by teachers of informal science institutions and, consequently, their impact on pupil learning.
