This interaction needs whole language in which language skills of speaking, listening, reading and writing; associated knowledge of vocabulary, meaning, syntax, etc.; and also, thinking skills are interwoven. This means that language should be kept whole and ＂if language isn＇t kept whole, it isn＇t language anymore＂ （Rigg, 1991, p. 522, cited in Richards ＆ Rodgers, 2001, p. 109）. In English as a Second Language/English Foreign Language （ESL/EFL） learning settings, improvement in one skill can affect the development of other skills. A particular course may highlight certain skills, but if the teacher is creative or specific tasks and problems are used in language learning settings, learners are provided with the opportunity to improve multiple, integrated skills. This paper aims at elaborating on critical thinking approach to language learning and introducing practical ideas for helping teachers to integrate language and thinking skills. It introduces 3 critical thinking activities （Dialogue journals, reading logs and literacy portfolios）, and also discusses how implementing them can serves as a way to integrate language skills. It also maintains that engaging learners in these activities helps them use authentic materials and solve problems of their own interest that in turn has a positive effect on student＇s motivation.展开更多

E-learning, as an alternative approach to traditional face-to-face education, is creating immense challenges for educational institutions to develop new approaches for the production and delivery of cost effective and efficient e-contents. Although, there have been many developments in web-based programmes, they have not fully attained their potential due to a variety of factors. These include: 1) lack of exchangeability between learning materials, 2) delivery mechanisms incompatible with the pedagogical design, 3) low student interaction and insensitive learning processes, 4) absence of intelligent online programme advice and guidance, 5) inflexibility in meeting diverse needs, and 6) institutionally centred ineffective implementation strategies. This paper addresses the critical elements for successful delivery of e-learning environments and then focuses on proposing a framework for the development of an integrated knowledge-based learning environment which has the potential to producer cost effective and personalised training programmes.展开更多

It is a question of the teaching skills whether the teachers can adroitly, effectively and skillfully adopt the advanced teaching methods to implement the teaching.展开更多
