新升本科院校教学质量监控体系构建与探索——以商洛学院为例

新建本科院校由于本科办学历史不长,经济条件相对较差,师资力量相对薄弱,教学条件相对简陋等诸多未解难题和困惑,如何立足地方普通高等学校自身特点,进行科学、系统的教学质量评价成为解决教学质量问题的关键。本文从商洛学院升本以来,不断更新教育理念,探索本科教育管理体制和运行体制,教学质量保障方面取得的一些实践经验来探讨新升本科院校教学质量监控体系构建。     

Effects of sodium ferulate on preventing steroid-induced femoral head osteonecrosis in rabbits

The aim of this study is to investigate the effects and possible mechanisms of sodium ferulate (SF) on anti-apoptosis in steroid-induced femoral head osteonecrosis in rabbits. Japanese white rabbits were randomly divided into three groups (control group, treatment group, and model group), each with 24 rabbits. The model and treatment groups were first injected with an intravenous dose of horse serum, 10 ml/kg, three weeks later with an intravenous dose of 7.5 ml/kg, and two weeks later with an intramuscular dose of methylprednisolone, 45 mg/kg, three times in order to establish rabbit models of osteonecrosis. Concurrently, the treatment group was injected with intravenous doses of SF 20 mg/kg for two weeks, once per day. Three time points, Weeks 2, 4, and 8, were selected after modeling was completed. Osteonecrosis was verified by histopathology with haematoxylin-eosin (HE) staining. The apoptosis rate of osteonecrosis was observed by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. The apoptosis expressions of caspase-3 and Bcl-2 were analyzed by immunohistochemistry and Western blot. The rabbit models of osteonecrosis were successfully established and observed by HE staining. SF was effective in intervening in apoptosis and decreasing the apoptosis rate in femoral head necrosis by the immunohistochemistry and TUNEL assay (P<0.01). Western blot analysis indicated that there were statistical significances in the protein levels of caspase-3 and Bcl-2 (P<0.01). SF has a protective effect by reducing the incidence of early steroid-induced femoral head necrosis in rabbits, effectively intervening in apoptosis through decreasing caspase-3 expression and up-regulating Bcl-2 expression.     

高校学业考试试题编制的质疑、实践与改革——以《课程与教学论》为例

高校学业考试对于高校人才培养有着积极的导向作用,而试题编制作为学业考试的重要环节,对于人才培养的导向作用尤为明显。目前的高校学业考试在试题编制方面普遍存在着缺失理性思维与系统设计的问题,已不能适应培养创新人才的客观需要。文章以"课程与教学论"课程试题编制的实践探索为个案,对于新型试题编制所应当包括的理论学习、实践运用及反思感悟三个部分进行了详细阐释,并提出了高校学业考试试题编制的改革思路。     

学科发展速度评价的两个文献计量指标

谈以人为本的德育观

高校德育工作必须坚持以人为本的原则,把培养社会所需要的、具有全面综合素质的、富有主体精神和创造力的“人”放在一切教育活动的中心,这是从事德育工作应树立的一种哲学观和方法论,是新时期高校德育工作实效性的关键,是培养德才兼备的新一代大学生的必然选择。

Vygotsky’s sociocultural theory in the context of globalization

The article reviews the social-educational theorization of the early Soviet psychologist L. S. Vygotsky (1896–1934) in the light of the impact of communicative globalization in educational practice. Vygotsky proposed four “genetic domains” for investigating higher cognitive processes: the phylogenetic (humans undergoing natural evolution), the cultural-historical (social activity of humans), the ontogenetic (individual lifespan), and the microgenetic (immediate events). Vygotskian sociocultural theory is widely used in educational research, especially Vygotsky’s notion of mediated development via tools and signs. Since Vygotsky, communicative globalization has transformed educational potentials. Nevertheless, provided adjustments are made to Vygotsky’s genetic method to incorporate time-space compression, the mutual presence of the genetic domains, and the glonacal heuristic, Vygotskian theory continues to be useful in socially-situated investigations of educational development and transformation, and opens another way into the global, for example investigation of the role of global mediation in learning.
