黎凯光 《思想理论教育导刊》1994,(4)
关于课堂教学效果的思考黎凯光提高课堂教学效果的着眼点是什么？我认为应该是增强吸引力和提高吸收率。增强吸引力是提高吸收率的前提，而提高吸收率则是增强吸引力的结果．那么，怎么才能增强吸引力和提高吸收率？我以为应从精选讲课内容，改革讲课方法，以及开展课堂教... 相似文献

为了提高图像的纹理细节,提出了一种分数阶对比度增强算法。首先离散化分数阶微分方程得到分数阶微分数值计算方法,并将其推广到二维图像空间,构造了数字图像的分数阶微分增强运算规则和增强模板。实验表明该分数阶微分增强算法能比较明显地增强图像的纹理细节,增强后的图像清晰度显著提高。 相似文献

提出了一种基于机器学习的耳语音可懂度增强方法.该方法利用已经训练好的2类支持向量机来估计一个二元时频掩蔽值,进而合成增强后的耳语音.输入支持向量机的特征向量GFCCs是基于听觉外周模型进行提取的,具有噪声鲁棒特性.在增强仿真实验中,将该算法同传统语音增强算法进行语音可懂度增强性能比较.客观评价和主观听力实验结果均表明,所提出的方法能有效提高含噪耳语音的听觉可懂度;相比谱减法和log-MMSE方法在低信噪比时无法提高语音可懂度,该方法在低信噪比时仍可有效提高含噪耳语音的听觉可懂度.此外,含噪耳语音通过所提出的方法进行增强后,其可懂度比未增强时明显提高. 相似文献

《金瓶梅》以写实的笔法,塑造了一批丫鬟形象,揭示了她们的悲剧命运,同时还在一定程度上反映了她们的婚姻状况。婢女被视为主人的私有财产,主人可以随意奸占,同时其婚配也完全由家主决定,即使被收为妾也不能彻底改变自己的地位。由于正常的婚配权得不到满足,婢女心存不满,往往会借出轨行为来满足自己的欲望。随着婢女买卖的合法化,婢女的生存环境更加恶化,她们的婚配更加困难。 相似文献

In this case study, the professional mathematics teacher identity (PMTI) of final year mathematics education students is investigated in terms of their self-perceived and actualised identity. These prospective teachers were required to discuss and describe their own PMTI in terms of three aspects: mathematics specialisation, teaching-and-learning specialisation, and caring. Subsequently, they were observed in the classroom, where the actualisation of their PMTI was considered in terms of the same three. The participants’ perceptions of their own PMTI and the actualisation of that PMTI in the classroom were found not to be congruent. While their self-perceptions regarding their prowess as Mathematics Specialists were accurate, since this is concretely tested as part of their studies, their self-perceptions as teaching-and-learning specialists and particularly as Carers, were not verifiable in their classroom practice. Espoused theory, theory that the individual perceives as true and valid, and which may thus be seen as intrinsic to their PMTI’s, is not necessarily enacted. 相似文献

The aim of this article is to problematize the ways class and gender are played out in adult students’ narratives about their occupational choice and future. Drawing on Beverly Skeggs, we analyse how students think about future occupations, what motivates them towards these and how they are able to form their future in relation to them. Taking on Sweden as a case, our results show that students’ narratives on their future occupations are classed as well as gendered. In their vision of future occupations, working-class students tend to focus on occupations helping and caring for others, while middle-class students tend to focus on work more as a means of fulfilling themselves as individuals. These differences are also gendered. Female students are more likely than their male counterparts to picture their future occupations in relation to having children and a family. This tells us that in the female students’ narratives, there tends to be a strong focus on caring – for their families as well as in future occupations. 相似文献

This article analyses the university experiences of 44 students with disabilities. The voices of Spanish students describe the reasons that lead them to choose a given university degree, their transition in the university, the perception they have of themselves as students and how they evaluate their academic results. This study was done with the biographical-narrative methodology using several different data collection techniques, such as narrative interviews, lifelines and photographs. Data analysis was based on an inductive coding system. The results of this study have enabled us to conclude that most of the students chose their degree course because they had a vocation for it, although their disability also influenced their decision. Some students had such a hard time during their first year that they had to change their course of studies. They thought they had to make a stronger effort than the rest of their fellow students, defined themselves as fighters and survivors, and valued this willpower as their main personal asset, above the outcome achieved. 相似文献

Research has highlighted the challenges that women face as mature-age students in higher education. The challenges are particularly acute when a woman is the first in her family to go to university. Many women begin their journey as students with considerable self-doubt and lack of confidence. They may also face an ongoing struggle to find a way to combine their studies with other family responsibilities. This article presents the reflections of 18 women enrolled as mature-age students at an Australian university campus. Their triumphs, achievements and self-discoveries, as well as their struggles whilst undertaking their studies, are explored. In presenting the reflections of this group, the transformative nature of these experiences is highlighted, not only for the women themselves, but also potentially for their families, particularly their children. These narratives of achievement and transformation ultimately provide inspiration to other women contemplating such a step as well as insight for academic administrators and teaching staff regarding the significant personal change this decision can engender. 相似文献

This article draws upon data from semi‐structured interviews with Australian Indigenous teachers to explore the role their mothers played in shaping their decisions to become teachers. The findings suggest that their mothers’ emotional involvement and investment in their sons’ and daughters’ education generated significant reserves of emotional capital upon which the teachers drew. Such capital, expressed by their mothers in a variety of ways, including encouragement, coercion and anger, motivated and inspired them to complete their schooling, to consider teaching as a profession and to take out teaching degrees, often in the face of enormous challenges and barriers. They understood teaching as presenting opportunities for their own upward class mobility as well as the chance for them to bring about social change for Indigenous people in general. I conclude by arguing the need to reconsider the dominant discourses in Australia around the aspirations of Indigenous mothers in regards to their children’s education and I also raise issues for further consideration and research. 相似文献
