中国考试 2024年第5期 36-45页

作者：曹梅单美贤南京师范大学南京210097 南京邮电大学南京210023

评价数据的伴随性采集是智能化测评的基础,可划分为具身伴随、数据空间伴随和数字化评价活动伴随三种类型。前两者囿于技术限度及伦理风险,尚难以普及到当前的真实学习环境中,而数字化评价活动伴随则是一条更为实用有效的路径。本文以... 详细信息

评价数据的伴随性采集是智能化测评的基础,可划分为具身伴随、数据空间伴随和数字化评价活动伴随三种类型。前两者囿于技术限度及伦理风险,尚难以普及到当前的真实学习环境中,而数字化评价活动伴随则是一条更为实用有效的路径。本文以学本评估理念为基础,建构面向学习段、学习性、学习化三种评估方式的全过程、多维度伴随性数据采集框架,并勾勒出评价数据伴随性采集的实用主义路径全貌。智能化测评的数据采集有必要从技术中心走向评价中心,注重人机协同,立足学习与评价本身的创新及其数字化转型,采集更多元的学生发展大数据,推动核心素养测评发展,彰显评价促进学习的真正价值。

为准确且精细地识别云相态,提出一种基于模糊逻辑识别云相态的优化算法,基于不同云粒子特征参数对T函数系数进行了调整。考虑了回波反射率因子衰减和温度对云相态识别准确性的影响,利用毫米波云雷达订正后的回波反射率因子、径向速度、谱宽和微波辐射计探测的连续时空温度,作为优化后的模糊逻辑算法的输入参数。优化后的模糊逻辑算法在原有云粒子相态(冰晶、雪花、混合相态、液态云滴、毛毛雨和雨滴)识别的基础上,还可实现对过冷水和暖云滴的识别。利用该算法对2022年2月6日陕西省西安市一次降雪过程的云粒子相态进行识别,将近地面的云粒子相态结果与同址地面降水现象仪记录的降水粒子相态进行对比,二者探测的相态有较高的一致性,说明优化后的算法能准确且精细地识别云粒子相态。

To cope with an increasingly turbulent environment, manufacturing firms increasingly implement integration practices to enhance flexibility in the production process. This research develops a framework to explore the relationships among organizational integration practices, manufacturing flexibility, and competitive advantage. The study develops valid and reliable instruments to measure these constructs, and it applies structural equation modeling to test relationships among these variables using a large sample. The results indicate strong, positive, and direct relationships between organizational integration practices and manufacturing flexibility, and between manufacturing flexibility and competitive advantage. The results also indicate that organizational integration practices enhance competitive advantage directly as well as indirectly by facilitating manufacturing flexibility.
