Coming to know about the body in Human Movement Studies programmes

This paper explores how a group of undergraduate Human Movement Studies (HMS) students learnt to know about the body during their four-year academic programme at an Australian university. When students begin an undergraduate programme in HMS they bring with them particular constructions, ideas and beliefs about their own bodies and about the body in general. Those ideas and beliefs are often challenged, disrupted or reinforced according to discourses and practices to which students are exposed and which they experience throughout their programme of study. The courses that these students take in their in HMS degree programme present to them different perspectives about health and the body. Some perspectives take the status of taken-for-granted truths and others are dismissed or ignored. Taking a Foucauldian perspective, this paper explores the dominant discourses and practices to which this group of students was exposed during their four years of academic formation, and the influences that this exposure might have upon their construction of the body and their formation as pre-service Health and Physical Education (HPE) teachers. The participants in this study were 14 students, 11 females and 3 males, aged between 18 and 26 at the time of the first interview. The data used for this paper were taken from a larger study and were analysed using a content analysis approach. Results suggest that some students may be heavily influenced by certain practices and discourses during their programme of studies, and that they embody dominant discourses of health. Furthermore, a possible change of thinking may occur across their academic programme, as a consequence of their engagement with a few alternative discourses presented during their academic programme, disrupting some of their previous beliefs and knowledge.

Latent Profiles of Reading and Language and Their Association With Standardized Reading Outcomes in Kindergarten Through Tenth Grade

The objective of this study was to determine the latent profiles of reading and language skills that characterized 7,752 students in kindergarten through tenth grade and to relate the profiles to norm-referenced reading outcomes. Reading and language skills were assessed with a computer-adaptive assessment administered in the middle of the year and reading outcome measures were administered at the end of the year. Three measures of reading comprehension were administered in third through tenth grades to create a latent variable. Latent profile analysis (LPA) was conducted on the reading and language measures and related to reading outcomes in multiple regression analyses. Within-grade multiple regressions were subjected to a linear step-up correction to guard against false-discovery rate. LPA results revealed five to six profiles in the elementary grades and three in the secondary grades that were strongly related to standardized reading outcomes, with average absolute between-profile effect sizes ranging from 1.10 to 2.53. The profiles in the secondary grades followed a high, medium, and low pattern. Profiles in the elementary grades revealed more heterogeneity, suggestive of strategies for differentiating instruction.     

完形默读法：汉语第二语阅读理解监控试验教学研究

文章以＂为意义而阅读＂为基本的阅读理念,把测量阅读理解和教材难易度的阅读填空（Cloze）测量法应用在第二语课堂阅读教学中,设计成＂完形默读法＂（Cloze Silent Reading Method）,作为阅读过程中的自我监控工具,让学习者能集中注意、调动先备知识与经验,主动与语篇交际。研究结果初步发现,初中二年级的受试在经过第一阶段完形默读历程后,其字面性理解力提升,推论理解力也有所提升;从教学意义来看,完形默读法能发挥理解监控的正面作用,促进学习者的阅读力,意味着第二语阅读过程之教学的一种突破。

听力理解模式及其在听力测试中的作用

聆听(Listening)是外语学习者接触外语和语音输入的主要途径之一，它对外语学习起着重要的作用。本文介绍了心理语言学的三种听力理解模式：“自下而上”模式(bottom-up)、“自上而下”模式(topdown)和“互动”模式(interactive)，并结合大学英语四级考试全真听力测试题，阐述了这三种模式对听力理解的重要指导作用。     

An Examination of Text Complexity as Characterized by Readability and Cohesion

To better understand dimensions of text complexity and their effect on the comprehension of adolescents, 103 high school seniors were randomly assigned to 4 groups. Each group read versions of the same 2 informational passages and answered comprehension test items targeting factual recall and inferences of causal content. Group A passages had a challenging readability level and high cohesion; Group B passages had an easier readability and low cohesion; Group C passages had a challenging readability level and low cohesion; and Group D passages had an easier readability and high cohesion. Students in Group D significantly outperformed students in Group C (g = 0.78). Although the effect sizes of comparisons among all groups ranged from g = 0.13 to 0.73, no other comparisons were statistically significant. Results indicate that adolescents’ reading comprehension is dually influenced by a text's readability and cohesion. Implications for matching readers to instructional text are discussed.
