Is academic tracking related to gains in learning competence? Using propensity score matching and differential item change functioning analysis for better understanding of tracking implications     

《Learning and Instruction》2020

This study analyzes gains in cognitive components of learning competence with respect to cohorts based on ability tracking in a Czech longitudinal study. Propensity score matching is used to form parallelized samples of academic and non-academic track students and to eliminate the effect of selective school intake. We applied regression models on the total scores to test for the overall track effect. Furthermore, we analyze scores and gains on the subscores and check for differential item functioning in Grade 6 and in change to Grade 9. While after 3 years, no significant difference between the two tracks was apparent in the total learning competence score, we did, however, find significant differences in some subscores and in the functioning of some items. We argue that item-level analysis is important for deeper understanding of the tracking implications and may provide the basis for more precise evidence-based decisions regarding the tracking policy.  相似文献   

Media Accountability and Journalists: To Whom Do Spanish Professionals Feel Responsible?     

María-Ángeles Chaparro-Domínguez  Juan-Carlos Suárez-Villegas  Ruth Rodríguez-Martínez 《Journalism Practice》2020,14(7):812-829

ABSTRACT

This paper analyses to whom Spanish journalists feel responsible. To achieve this objective, we sent out a survey to Spanish journalists to ascertain their opinion on this question. The journalists’ point of view was then compared with that of the general public though six focus groups consisting of Spanish citizens from six cities in Spain (Barcelona, Castellón, Madrid, Sevilla, Mondragón and Santiago de Compostela). Lastly, five in-depth interviews were conducted with journalism experts (e.g., directors of professional journalist associations). The main results show that the journalists feel particularly responsible to their conscience, the journalism code of ethics and their sources. The citizens, in contrast, believe that journalists should be responsible to the audience. We contextualised the Spanish finding in the European context by comparing our results with those derived from a study among European journalists.  相似文献   

Coping with cultural differences in healthcare: Chinese immigrant mothers’ health information sharing via WeChat     

《Int J Intercult Relat》2021

Immigrants face the challenge of obtaining culturally specific health information and adapting to a new healthcare system. Through qualitative content analysis, this study explores how Chinese immigrant mothers use the ethnic social media—WeChat to engage in health information sharing and coping with cultural differences in healthcare between the U.S. and China. Based on the data collected from one WeChat group in a metropolitan city in the northeastern U.S., Chinese immigrant mothers frequently discuss the topics of “doctors and hospitals,” “insurance and cost,” “medicine and treatment,” and “alternative health care.” They constantly compare Chinese health care beliefs and practices with western ones. They adopt various acculturation strategies to manage the cultural differences in healthcare beliefs, practices, and systems. We call for future research to further examine immigrants’ health information sharing via social media and consider acculturation as coping strategies or processes in the health communication context.  相似文献

培养湖州新农村“专业农民”的对策     

郑宁国  许伟达  王柱国 《湖州职业技术学院学报》2011,9(2):5-8

在“十一五”期间,湖州市新农村建设在科技创新、产业发展、村镇规划建设、基础设施建设、生态环境建设等方面培养了大批“三农”人才,创建了新农村建设的“湖州模式”。这为贯彻落实中共中央国务院《国家中长期人才发展规划纲要（2010—2020年）》“以用为本”的精神打下了扎实的基础。作为目前参与湖州“美丽乡村”建设活动的新农民——农村领军人才,必须学习现代科学知识,围绕湖州农业主导产业发展方向,将自己培养成“专业农民”,让技术变成看得见、摸得着的产业,以增强农业产业化组织的带动能力,发挥专业合作社对广大农户的影响力和带动力。  相似文献
