论艺术教育的意义与价值

社会上存在很多对艺术教育的迷思,比如,艺术与教育的关系是什么?艺术是否可教?艺术完全是灵感的产物吗?艺术是否值得被教?艺术教育的作用是什么?符号理论可以表明艺术教育的可行性及价值。我们不应该将艺术仅仅视为达成某一具体目的的手段,而应该将其既看作目的,又视为手段。艺术完全是灵感的产物这一假设是没有根据的,学生的感觉回应和情感反应可以被教育,艺术教育是可能的,也是有价值的。     

Chinese TEFL teachers’ perceptions about research and influences on their research endeavours

English has always occupied a key position in China’s education. The quality of English education depends largely on the quality of the English teaching force. Improving the overall quality of Teaching English as a Foreign Language (TEFL) teachers entails advancing both their teaching and research competence. This study, with its focus on Chinese TEFL teachers working in a higher education institution, was set up in a context where Chinese higher education colleges are being transformed into universities and research is becoming a crucial aspect of all teachers’ work. This small-scale case study investigated a group of Chinese TEFL teachers’ perceptions about research and their individual and workplace characteristics that influenced their research endeavours. The findings revealed that Chinese TEFL teachers recognised the significance of research for teaching, professional growth and career advancement. However, lack of individual characteristics such as research and disciplinary knowledge, confidence in research and intrinsic motivation impeded their research efforts. Their institution and departments seemed to encourage research; yet, more specific financial and academic support to start and sustain their research endeavours is required. This study’s findings provide implications for both individual teachers and their institutions to engage TEFL teachers more actively in research.     

Cognitive-inspired domain adaptation of sentiment lexicons

Sentiment lexicons are essential tools for polarity classification and opinion mining. In contrast to machine learning methods that only leverage text features or raw text for sentiment analysis, methods that use sentiment lexicons embrace higher interpretability. Although a number of domain-specific sentiment lexicons are made available, it is impractical to build an ex ante lexicon that fully reflects the characteristics of the language usage in endless domains. In this article, we propose a novel approach to simultaneously train a vanilla sentiment classifier and adapt word polarities to the target domain. Specifically, we sequentially track the wrongly predicted sentences and use them as the supervision instead of addressing the gold standard as a whole to emulate the life-long cognitive process of lexicon learning. An exploration-exploitation mechanism is designed to trade off between searching for new sentiment words and updating the polarity score of one word. Experimental results on several popular datasets show that our approach significantly improves the sentiment classification performance for a variety of domains by means of improving the quality of sentiment lexicons. Case-studies also illustrate how polarity scores of the same words are discovered for different domains.

THE NATURE OF COUNSELLING

The counsellor functions in a broad spectrum verging upon psychotherapy at one boundary and upon advice giving at the other and may also enrich the skills of others in the caring professions. In all cases, receptivity to the individual's thoughts and feelings is required. This capacity is enlarged by the counsellor's ability to extend his or her own self‐understanding and by willingness to learn from the client.
