【正文】 Besides the judging criterion based on the operating platform, there are other yard sticks to subclassify the various kin。 while the latter refers to the programs that are so large and have to be delivered on the Internet. And the user has to visit the specific web site to access them. Apparently, the most important distinction between the two types of software is the size of program. And this often means the difference of content and capacity. And as for the quality of the internet base accessibility, more often than not, it is limited by the speed of the end user’s internet service.Language learning courseware‘Elearning refers to education via internet and relative service ’‘Elearning offers the chance to study anytime anywhere and therefore makes life study a possibility. ’‘…it (Elearning) will change the relationship between teacher and student, and thus change the nature of education. Some education targets will be achieved successfully but it shall never replace traditional classroom teaching.’In summary, elearning is a study and teaching activity involving internet and other digital resources, which makes full use of uptodate munication system and abundant resources realized through information technology so as to build up a new study approach, which changes the relationship between students and teachers and further more, the nature and structure of traditional education. (何克抗2002)The “Education Technology White Paper 2000” published by the Ministry of Education USA afforded several descriptions on “elearning” as follows: Technological Methods of Blended LearningAlong with the development of information technology, the technological methods used by language teachers in blended teaching delivery have been diversified. Before we define the scope of blended learning we should first of all, have a clear definition of elearning.“Elearning tends to be short, targeted, task driven, and episodic, while classroom learning tends to be longer, less welltargeted and programmatic. For some learning tasks the former is ideal?！癇lended learning is the term used to describe learning or training events or activities where elearning , in its various forms, is bined with more traditional forms of training such as ‘classroom training’”. (Stockley, 2003) This bees more plex as we try to define what the various forms of elearning are. One needs to consider the content or information of the elearning course as well as instructional methods or techniques that help people learn the content. According to Clark and Mayor (2002), there are five types of content in elearning. Facts are specific data, concepts are categories that include multiple examples, a process is a series of events, a procedure is a stepbystep process, and a principle is a guideline for performing a task.Probably the most interesting and least considered aspect of elearning courses is the reason they are used and how they fit into the overall blended learning plan. Elearning is often seen as a business solution to training programs for both basic and plex skills required to acplish some specific task. Most of these programs were created for economic reasons instead of pedagogical needs. (Schank 2002, Rsoenberg 2001). Rosenberg, for example, puts the fact that “elearning lowers costs” as the first of the ten benefits of elearning. Other benefits include enhancing business response, building munity, flexibility of schedule and content (scalability, consistency or customization) and timeliness. Note that most of these concern deployment and administration have little to do with pedagogy. Chapter Three Blended Learning What is Blended LearningPractice in recent years has shown that there are ample reasons for substitution of puter for conventional teachers in language learning. Is the age of teacherless language learning really ing? Although some of the puter’s functions provided by technological advancement seemingly pose threats to teachers’ conventional position and roles in the classroom. However, according to Taylor’s assumption of “puter as tool”, the role of puters in language teaching is claimed to be auxiliary, merely an aid under the control of the teacher. In other words, no matter how far the wheel of the puter could go, the teacher would always sit on driver’s seat.Tool programs, such as wordprocessing and database management programs, are another type of program which, though not created for CALL, can be used in language learning. Wordprocessing programs perform editing functions, helping students with their writing in the foreign language in the same way as they help them in their native language. They can check words used against a dictionary stored in memory, advising students of incorrect vocabulary or gender. They can also check on capitalization and punctuation, reminding students of French that months and days of the week start with small letters, students of Spanish that questions must be preceded by a punctuation mark, and students of English those adjectives of nationality must be capitalized. With these programs, position writing bees a dynamic experience in which the student learns to modify a text continually in order to improve it. Thus far, these programs exist mainly in English for use with the predominant microputers, but they are sure to bee available for other languages in the near future. Games involving vocabulary or culture may be played in the target language. Some are like the video and puter games that children and students already play in their native language. Adventure games, for example, in which the user interacts with a program to solve a mystery or to survive in an imaginary environment, provide an excellent CALL experience for students. Requiring decision making on the part of the players and including a great deal of text display, these games promote prehension skills and thoughtful response. At th
