高中美术学业水平评测新模式探索

美术作为一门艺术性很强的学科,在高中美术教学中,要充分发挥美术教学的艺术价值,积极探索美术教学的新模式,加强教学艺术性。同时,在教学评价中,以学生核心素养为基础,对学生图像识读、美术表现,审美判断、创意实践以及文化理解进行评判,促进学生美术科学素养。本文分析高中美术学业水平评测新模式,探讨其对于高中美术教学的促进作用,以供参考。

“百练”:一个程序设计技能训练与水平测试平台

"百练"是一个源自四年前为支持ACM程序设计大赛训练与赛事开发的系统。近几年来,出于该系统一直良好运行带来的信心以及对中国大学生学习程序设计需求的理解,系统的软件和硬件最近都得到了升级,文章阐述了该系统情况及其应用情况。

计算机辅助汉字书写教学技术研究综述

传统的汉字书写教学方法具有一定的局限性,为此人们开始关注计算机辅助的汉字书写教学技术。它主要研究汉字书写规范的智能化、自动化评判方法以及可视化的反馈形式。对近20年来计算机辅助汉字书写教学技术的发展情况进行了综述;详细介绍了数字化展示、书写评判、水平评测等几个研究分支的特点、关键问题以及主要成果;结合相关技术的发展和需求的变化,提出了汉字书写数字化教学技术在未来的发展方向。

The Role of Heat Shock Protein 70, IgE and MMP-9 in Detecting Early Minor Myocardial Damage and Evaluating the Efficacy of Coronary Artery Bypass Grafting （CABG）

The objective of this research was to identify levels of heat shock protein 70 （Hsp 70）, total immunoglobulin E （IgE） and matrix metalloproteinase-9 （MMP-9） before and after coronary artery bypass grafting （CABG） surgery. Hsp 70, IgE, MMP-9, creatine phosphokinase-MB （CPK-MB）, and lactate dehydrogenase （LDH） levels were measured in normal subjects （n = 20）, and in patients with chronic stable angina pectoris who were referred for elective CABG, before and after performing CABG-surgery （n = 20）. Compared with normal subjects, increased Hsp 70 and IgE levels, unchanged MMP-9 level, and activities of CPK-MB and LDH were found in the pre-operative patient group. Hsp 70 and IgE levels in the post-operative period were significantly reduced when compared to pre-operative period. Hsp 70 and IgE might be used as markers for detection of early minor myocardial damage, and coronary insufficiency with less overt damage than myocardial infarction, as significant changes in their levels appear before occurrence of in any changes in the levels of MMP-9, CPK-MB and LDH. Besides, Hsp 70, and IgE returning to the normal levels after CABG surgery, suggest that they could be helpful to evaluate the effect of CABG surgery.
