动物医学专业形态学实验教学模式改革初探

动物医学专业形态学实验教学是动物医学本科教学体系的重要组成部分,为了提高实验教学效果,对形态学实验教学模式进行了改革:将动物解剖学、组织胚胎学和病理学的实验内容划分为基本实验项目模块和形态学综合实验模块,通过实验课程内容的整合,减少了实验内容的重复率,加大了学科内容知识点的联系,增加了综合性实验和研究性实验内容.问卷调查显示,本次所进行的动物形态学实验教学模式改革取得了较好的效果.

大面积建成区建筑密度遥感制图产品的精度验证

大面积建成区建筑密度遥感制图产品能够提供土地开发强度与人类居住环境的基础信息,是支撑人居环境研究和土地利用规划的重要数据。全球人类居住区层（global human settlement layer,GHSL）是由欧盟联合研究中心负责的大面积人居环境制图项目,建成区建筑密度遥感制图产品是GHSL重要的组成部分。目前该产品在欧美地区已经完成了GHSL建成区建筑密度遥感制图产品的验证。然而以中国为代表的东亚区域的建筑物形态和城市布局与欧美等区域有较大的差别,有必要在亚洲地区对其进一步验证。以中国的5个典型城市（上海、西安、长春、昆明和乌鲁木齐）大面积单体建筑物分布图为基础,通过聚合分析和邻域关键点搜寻匹配等算法,生成中国建成区建筑密度栅格图像产品作为验证数据,然后通过回归分析等方法,在像元尺度上对GHSL建成区遥感制图产品进行评价验证。结果显示,GHSL建成区建筑密度产品在较低分辨率下可以反映中国地区建筑密度情况,但在较高分辨率下在高值区过高估计密度。本研究可以为中国地区研发建成区建筑面积密度产品提供依据。     

Extended Validation of the Korean Version of the Quality of Life Survey

In this study, we examined the factor structure and reliability of the Korean Quality of Life (KQoL) survey and compared the KQoL survey to both the World Health Organization Quality of Life-Brief Version (WHOQOL-BREF) and the Satisfaction with Life Scale (SWLS). We also assessed associations between KQoL scores and physical activity (PA) participation. Participants were 557 (male = 281, female = 276) healthy Korean adults with ages between 18 and 71 years (M = 33.2, SD = 14.2). Results of confirmatory factor analyses confirmed the 7-subscale model and indicated acceptable values supporting convergent validity (χ² = 1,678.758, df = 443, p < .001, RMSR = .045, RMSEA = .071, TLI = .880, CFI = .892). Correlations of KQoL subscales with similar subscales of WHOQOL-BREF and with SWLS supported concurrent validity. Results confirm that the KQoL survey can assess multidimensional aspects of quality of life (QoL), including spiritual, physical, social, and psychological. KQoL scores were positively related to PA participation, in line with previous research supporting the positive association of PA with QoL.

Validating Student Score Inferences With Person‐Fit Statistic and Verbal Reports: A Person‐Fit Study for Cognitive Diagnostic Assessment

The goal of this study was to investigate the usefulness of person‐fit analysis in validating student score inferences in a cognitive diagnostic assessment. In this study, a two‐stage procedure was used to evaluate person fit for a diagnostic test in the domain of statistical hypothesis testing. In the first stage, the person‐fit statistic, the hierarchy consistency index (HCI; Cui, 2007 ; Cui & Leighton, 2009 ), was used to identify the misfitting student item‐score vectors. In the second stage, students’ verbal reports were collected to provide additional information about students’ response processes so as to reveal the actual causes of misfits. This two‐stage procedure helped to identify the misfits of item‐score vectors to the cognitive model used in the design and analysis of the diagnostic test, and to discover the reasons of misfits so that students’ problem‐solving strategies were better understood and their performances were interpreted in a more meaningful way.
