The Design and Application of Primary and Secondary Teacher Training Oriented Micro-Course

With the “Micro-era” coming, micro-course becomes a new popular course form because it is short, small, refined, and efficient with various teaching methods and wide fields. Using micro-course in teacher training can adapt to teachers’ learning features and meet their development demands. The quality of micro-course design decides the effectiveness of training. This paper presents the learning features and requirements of primary and secondary teachers as well as the superiorities of micro-course application, builds primary and secondary teacher training oriented micro-course design mode, and uses a series of micro-courses “Tutoring Teaching in the Multimedia Environment” of “National Training Program (2014)”—rural primary and secondary teacher distance training program in Guizhou province as an example to verify the mode.


Introduction
Primary and secondary teacher training is an important approach to enhance the teaching skills.Fast-paced life proposed new requirements to teacher training, and the traditional training model could not meet the needs of teachers' professional development.Nowadays, micro-course application is widespread with time going by.Combining micro-course with teacher training can promote the formation of a new training mode.At present, most of the research on micro-course concerns its application in basic education, so it is necessary to pay more attention to micro-course application in teacher training, especially the design and implementation of it.We make a deep observation and discussion, put forward a specific micro-course design mode, give examples to verify the feasibility and effectiveness of the mode, and hope that the micro-course can be applied to teacher training better.

The Characteristics of Primary and Secondary Teacher Training
Teacher training is carried out in full swing every year.With the development of information technology and the popularity of mobile terminals, teacher training is advancing with the times, changing greatly and reflecting new features of this era.

Lifelong Learning
Since the mid-1960s, under the strong advocacy, promotion and popularity of UNESCO and other relevant international organizations, "The First World Conference on Lifelong Learning" was held in Rome in 1994, and then lifelong learning became a consensus in the world.Knowledge updates extremely fast for the rapid development of science and technology today.As basic education practitioners, primary and secondary teachers shoulder heavy responsibilities of teaching children and teenagers, so it's more necessary for them to hold the belief of lifelong learning.In order to maintain their own progressiveness and impart the most forefront knowledge of this era, teachers need to keep learning.

Fragmented Learning
Fragmented learning which can be carried out anytime and anywhere has always been here, especially in adult learning (Shan & Wang, 2013).Schoolteachers are busy with daily work and there are many things to disperse their energy.They spend little time participating in training whose time and location is comparatively fixed.They need to make use of fragmentary time to learn related knowledge (Yan, Liu, & Liang, 2014).Long time module training is becoming increasingly unrealistic, and it's difficult to achieve the expected results.Many findings show that the "Attention Mode" of Internet age is just 10 minutes, that is to say learners' attention can be fully focused only within 10 minutes.Therefore, fragmented learning will become a new mode for teacher training.Teachers take advantage of fragmentary time to learn to enhance the professional technology.

Self-Learning
Malcolm Knowles, the famous American adult educator, puts forward five characteristics of adult learning, and he emphasized learner independence, existing life experience, serving the demands and problems as the center, learning motivation more coming from inside (Fang, 2012).As adults, teachers have a more clear perspective of the content and importance of learning through work practice.Teachers' self-discipline is strong.They can resist various interference in the network and the external environment consciously, control their own behavior rationally, and carry out study initiatively.

The Demands of Primary and Secondary Teacher Training
With humans entering the Internet age, the learning style of teachers in primary and secondary schools transformed gradually, and the traditional teacher training can no longer adapt to teachers' study habits today due to its own limitations.The rapid development of information technology, the diversification of teachers' learning style, as well as the accelerating pace of modern society all raised new requirement to teacher training.

Free Time and Space
The traditional training mode gets teachers together at the identical place and unified time, which requires teaching experts, teachers and other relevant staff to arrange corresponding time to arrive at the specified location and complete the training.Both the time and space is relatively fixed.Teachers play a variety of social roles, assume multiple responsibilities and undertake diverse work, which makes most of their spare time is in holidays.If all of teachers' on-the-job training and in-service refresher are arranged in winter and summer vacation or during a certain period, the interval between courses is so long that the training is intermittent and it's difficult to combine training with teaching practice, which results in inefficient training (Wang & Hao, 2013).Therefore, teachers need the training whose time and space is relatively flexible.They not only can make full use of usual short free time, but also can practice new skills in class instantly.

Individual Curriculum
Adults attach great importance to the practicability of knowledge, and their motivation of learning is more diversified.Their study is timely and useful oriented, and to solve the problem is the core.Adult learning is mainly to meet the needs of the society and life.They know well about their training requirements and goals, and those clear objectives make adult learning definitely targeted (Zhou, 2013).If we adopt a uniform training content and steps, it is unavoidable that the enthusiasm of some teachers will be weakened and teachers' spare time will be wasted because the discipline backgrounds, teaching experience, education level, and learning preferences of each teacher are different.We should pay more attention to the content and process personalization of teacher training courses, meet teachers' various learning needs, make them choose what to learn and arrange the pace freely according to their own requirements so that they can make the best of spare time effectively to conduct self-learning.

Effective Support
In order to encourage the majority of teachers to learn actively and strive to forge ahead, the government as well as relevant departments ought to issue the corresponding policy and invest money in a planned way.Besides, primary and secondary schools should establish partnerships with universities so that universities will open the extensive library resources and literature database to schoolteachers and provide sufficient teacher force to support the teacher training.Each teacher has the right and obligation to improve capabilities constantly.Notifications of related training programs on teacher professional development should be published online openly and transparently to ensure that every teacher have a fair opportunity to learn.

The Advantages of Micro-Course in Primary and Secondary School Teacher Training
Micro-course, also named as micro-lecture, is a new kind of online web video course which is scene-oriented and able to support multiple learning styles.It is designed and developed for a certain subject knowledge point (such as emphasis, difficulties, doubts and exam points, etc.) or teaching link (such as learning activities, themes, experiments, assignments, etc.) and focuses on micro teaching video for the main carrier (Hu, Huang, & Li, 2013).Micro video serves as the core of micro-course, which is short, generally 5 to 8 minutes, but no more than 10 minutes.There are teaching courseware, class exercises, feedback evaluation and interactive Q & A, and many other supporting resources.The capacity of micro-course is small.The video format is usually streaming media (such as rm, wmv, flv, etc.) (Hu, 2013) which supports network online play.In general, the total capacity of micro video and the complete set of auxiliary resources is about tens of megabytes.Micro-course has the focused emphasis and clear theme to explain one knowledge point or record a teaching link.Meanwhile, micro-course is also semi-structured, dynamically generated and easy to expand.Applying micro-course to teacher training has the following advantages:

Breaking through the Restrictions of Time, Space and Personnel
Compared with the traditional teacher training, micro-course which is an online training mode can meet teachers' needs of arranging learning time and place flexibly.Teachers can browse the online courses and gain new knowledge within 10 minutes in their spare time.Traditional training can only accommodate a small number of teachers due to the limited classroom space.However, online training can absorb in more trainees so that teachers have more opportunities to undergo further training.Integrating micro learning into teachers' daily life makes study more humanizing, which is conducive to arouse teachers' learning enthusiasm, avoid burnout emotion and enhance the sense of professional happiness.

Accurate and Reusable Knowledge
Micro-course takes the form of video recording, which can relieve the stress of experts and avoid unnecessary mistakes effectively.During the production process of micro video, teaching experts can check the teaching content further to remove the redundant information and obtain reviews from other teachers and experts timely.Then they should conduct adequate reflections and summary in order to maximize the optimization of teaching behavior and ensure the simplicity and accuracy of knowledge.The micro-courses will be uploaded to the network platform after finished so that teachers in different schools and different regions can share the high-quality resources together.Both teachers who are at the school and prospective teachers who will be recruited for a certain period to come can use these resources.It realizes the reuse of resources and reduces the cost of primary and secondary teacher training.

Abundant Resources and Diverse Methods
Although micro-course is "micro", it has multiple resource types and self-sufficiency.Micro-course is based on micro video, and provides courseware, relevant materials or links for expanding learning, platform for discussion, practice and other resources to teachers, which offers strong support for their self-learning.The teaching methods of micro-course are flexible and varied.For different teaching content, it can be made by different software and tools, and presented through appropriate forms, such as pictures, PPT, Flash, movie clips synthesis, operating demonstrations and so on, which transforms the abstracts into visualizations to help teachers understand the training content.They can choose apposite resources and develop a learning pace according to the actual situation and their own needs, which avoids lots of problems, such as learning repetition, learning difficulties, shallow content, and achieves the personalized development.

Extensive Communication and Timely Feedback
Adopting micro-course in primary and secondary teacher training is able to provide online communication and discussion support for teachers.On the network platform, teachers can raise questions, express their own opinions, discuss with other teachers, share the learning outcomes with each other, and draw on teaching methods and experience from others.Teaching experts can grasp the effect of the training by analyzing the feedback from teachers.They can carry out the corresponding online Q & A activities according to teachers' questions and help teachers solve learning problems timely.The interaction among teachers as well as that between teachers and experts is displayed on the platform openly, which is helpful to exert the advantages of collaborative learning, promote the exchange of different ideas, and come up different ideas.

Micro-Course Design Mode
Micro-course is not only a job about resource development, but also a complex systematic task including the design, planning, construction, application and research of online course (Hu, Huang, & Li, 2013).The instructional design of traditional teacher training is an approach based on long-time module, but it's no longer applicable to the design of the micro-course.Teachers' learning psychology and habits have distinctive group characteristics.The micro-course design of teacher training must meet teachers' training needs, take full advantage of the micro-course, satisfy teachers' individual development, and help them upgrade their professional skills.Thus, micro-course design is a very important job which is related to the effectiveness of teacher training.
Early studies on micro-course tends to locate it in the "micro resources composition" and focused on resource construction, especially the micro video development, but the degree of concern for the design of learning activities is relatively low.Actually, learning activities plays a crucial role to ensure the final quality of learning (Huang, Wang, & Li, 2009).Micro-course design should give more consideration to the design of learning process rather than that of content, and support learners' deep cognition of learning content by designing effective learning activities (Yu, & Chen, 2014).Thus, the micro-course design for primary and secondary teacher training should be based on the teachers' learning characteristics and demands.It should guide teachers to conduct self-learning and collaborative learning as well as participate in the evaluation and feedback via problem orientation, activity design, and circumstances creation.
The learning time, learning goal and content granularity of micro-course has micro features, which makes the learning resources and related activities of micro-course are different from those of general course.Micro video, the core of micro-course, as well as other support and scalability resources(such as "micro teaching plan", "micro exercise", "micro courseware", "micro reflection", and "micro comment") for teaching supporting form a semi-structured, web-based, open and situational environment whose resources are dynamically generated and teaching application is interactive (Hu, Huang, & Li, 2013).In view of this, we construct the primary and secondary teacher training oriented micro-course design mode (Figure 1

Prophase Analysis
Although micro-course makes learning at anytime and anywhere a reality, this flexible approach to learning puts forward higher requirements for teaching.So we must make a detailed analysis of the entire application process when we design micro-courses.(1) Learner Analysis.At present, learners have become the subject of class.As a group, teachers have their unique learning preferences, and we should master teachers' learning features comprehensively by learner analysis.(2) Demand Analysis.Teachers are adults whose learning is demand-centered.We should grasp teachers' learning requirements in order to ensure the micro-courses that we design can stimulate their learning motivation and meet the learning needs.(3) Target Analysis.The purpose is to determine the goal that teachers should achieve after learning.( 4

Resources and Activities Design
This part includes "Micro Teaching Plan Design", "Micro Case Collection", "Micro Exercise Design", "Micro Courseware Making", "Micro Activities Organization", etc. Micro-course designers should always keep in mind that the trainees are primary and secondary teachers.Meanwhile, they should take full account of micro-course learning resources on the basis of a clear understanding of curriculum goals, such as the preparation of micro teaching plan and micro courseware before class, the selection of micro case for helping teachers understand the learning content, the design of micro exercise for testing teachers' knowledge mastering situation and so on.In order to take advantage of the network platform in micro-course learning environment and support teachers' deep cognitive of learning content, teaching activities organization is crucial.Organizing corresponding topic discussion opportunely will contribute to deepen teachers' understanding of the subject and correct some misconceptions timely.It is noticeable that micro-course's capacity cannot be large.Even though micro-course is rich in resources, we should choose appropriate media and methods to present different content.A micro-course only talk about one knowledge point to make sure that the content is primitive and within 10 minutes.The space and time of teaching and learning in micro-course is separated, so there should be relevant background introduction of teaching at the beginning.The introduction should be attractive, be able to stimulate study interest and relieve the cognitive load.The cases in micro-course should be in line with the theme, typical, close to teaching reality, easy to understand, and convenient to remember.The important concepts should be stated clearly.If some courses contain much theory, we should provide the relevant links or documents to teachers so that they can know about the basic concepts and principles.The skills teaching should be clear.It must tell learners what to do and what not to do.There should be appropriate questions and diverse questioning strategies to promote teachers to think about the content.At the end of the micro-course, a brief summary is needed to summarize the main points, clarify the ideas, and emphasize the important and difficult points.

Micro-Course Development
Micro-course development consists of recording micro-video as well as making related supported and extended ancillary resources.Micro-course development is the process that designers transform the "micro teaching plan" into the "micro script" which has clear objectives and structure and is easy to operate, then make training materials, carry out micro teaching activities, shoot and edit the micro video depending on the micro-course design.There are a variety of methods to make micro video.For instance, "Khan Style", namely the electronic blackboard system combines with screen recording software."Software Style", that is to say using some common micro-course production software, such as Photoshop, Flash, PowerPoint, The Geometer's Sketchpad, Corel Video Studio, Show Me, Edu-Creations, etc. "Recorded Course Style" is using digital video equipment to record real teaching situations, editing the video with corresponding software, and implementing micro treatment on the courseware and exercise."Blended Style" means making the micro-video via the integrated use of various methods such as augmented reality technology.Micro-video is the key resource of micro-course, so we should attach importance to choosing appropriate media and strategies.There should be attractive introduction, clear hierarchy, suitable questions, and a brief summery.In addition, we must advert the importance of teaching process integrity and never skip any step.The logical relations between steps should be explicit.Colored lines, symbols, graphs and other prompts can be used to mark the emphasis and difficulties.Subtitle and mind mapping can supplement the content which is not easy to explain clearly.If the chart is complex, the partial content should be amplified to enable teachers to see the details clearly.The picture should be concise and beautiful.The color of text and background should match reasonably.Slides switching cannot be too quickly or too often.The icon, background, and portrait which has nothing to do with the teaching content should be deleted.The environment of video recording must be quiet (Li, 2013).

Training Implementation
Micro-learning resource package will be uploaded onto the micro-course platform, and it will be applied after audited and published.Teachers login with their account and then they can begin to learn.Teachers are able to arrange the learning pace independently during the training.They can watch the micro video first, then read relevant cases and expand materials, next take part in the course activities on the platform where they can exchange learning experiences with others and discuss difficulties with experts to solve those problems in time via collaborative learning.At the same time, micro-course learning system generates study record for teachers and administrators release notifications at regular time to remind teachers to take notice of learning progress and participating in related activities.

Effect Evaluation
The micro-course needs teachers who join in the training to evaluate the content, design, process and support by micro feedback and micro comment in light of their own situations and experiences to look into whether the training achieves the expected goals, whether the teachers' study demands are met after learning, whether the teachers adapt to micro-course training mode, and gather their advice and suggestions on the application of microcourse in teacher training.

Reflection and Modification
According to the questions raised in training, the completion status of exercise, the evaluation of training, as well as the comments from other experts, micro-course designers should reflect every aspect of the micro-course comprehensively, including the resource design, activities organization, process supporting and so on.Afterwards, designers adjust the inadequacies of micro-course dynamically to optimize the training constantly.

The Example Analysis
The series of micro-courses "Tutoring Teaching in the Multimedia Environment" of "National Training Program (2014)"-rural primary and secondary teachers distance training program in Guizhou province serves as an example.
With the "Teacher-led, Student-centered" classroom role concept put forward and the development of information technology in education, primary and secondary school classroom enters the multimedia teaching era.It requires primary and secondary teachers to transform their teaching methods adaptively.The Micro-course "Tutoring Teaching in the Multimedia Environment" is added in this national training program, which contributes to guiding the first-line teachers to cope with the change of times correctly and easily, learn about the similarities and differences of tutoring teaching under the multimedia environment and traditional teaching, grasp the components and methods of multimedia tutoring teaching design, use multimedia reasonably, as well as provide students with proper guidance and improve teaching quality.In the smooth network environment, teachers login with account and appropriate equipment to enter the learning community and then take the course to learn.
"Tutoring Teaching in the Multimedia Environment" is divided into 16 micro-courses: "Comparing the Two Teaching Plans", "Tutoring Teaching in the Multimedia Environment", "Tutoring Teaching Design", "Teaching Content Analysis", "Learner Characteristic Analysis", "Learning Style Analysis", "Teaching Targets", "Teaching Key and Difficult Points", "Teaching Method", "The Choice of Teaching Method", "Multimedia and Teaching", "The Basis and Method of Choosing Teaching Media", "Interactive Electronic Whiteboard and Touch TV Application in Teaching", "The Flow Chart of Teaching", "Teaching Reflection", "Education Evaluation".
The relevant materials involved in the micro video, including "Cases", "Homework", "Learning Content Structure", "Learning tips", "Teaching Activities", "Core Concepts", "Expand Information", "PPT", "Reading Materials" and "Teacher Profile" are placed in the "Auxiliary Resources" section, which is to control the capacity of micro video and make it convenient for teachers to learn.After logining, teachers enter the learning platform, then they can firstly know about the main content of the topic "Tutoring Teaching in the Multimedia Environment" and construct the knowledge framework through the "Guidance Directory" combining with the "Theme Introduction", "Learning Content Structure", "Learning Tips" and "Core Concepts" under the video window.They can view the "Teacher Profile" to know the instructor.Then, teachers watch the micro video to learn related content.They can take notes while watching according to their own learning habits.If the knowledge is difficult to understand, they can locate freely and view it again.Teachers can read the teaching plan samples and teaching cases which are claimed in micro video directly or download them to the local computer to read at the "Cases" and "Expand Information" under the video window.PPT used by experts when teaching can also be downloaded to facilitate teachers' self-learning.At the end of micro video, there are questions and exercises about the topic.After watching the video, teachers can download the "Teaching Activities" and "Homework" at the resource plate, including checking related theory before class, reading extend cases, discussing the subject, reflecting teaching design and so on to consolidate the knowledge through the practice.In addition, teachers can also download extend resources in the "Resource Sharing" plate, including "Discipline Resource" and "Platform Resource".
To solve the problems that teachers may encounter in the learning process and promote collaborative learning, teachers have their own study groups in the learning platform.They can share learning experience with others in the Course BBS including "Learning Exchange" and "Homework Discussion" to strengthen the interaction among teachers or between teachers and experts.In the learning process, when teachers have their own opinions or questions of the theme, they can post at the "Learning Exchange" in Course BBS to share ideas with others who are in the same period to brainstorm.The problems about homework can be posted at the "Homework Discussion" in Course BBS.Other teachers show their views or answer the questions by replying.Except the interaction among teachers, experts organize "Online Q & A" activities of corresponding topics from time to time, which maintain 2 hours every time to assist teacher collaborative learning.Teaching administrators will publish the starting time of the "Online Q & A" at the "Notification and Status" plate in advance.Teachers should check the notice in time, and ask questions on the BBS during the specified period.Experts on duty will give the immediate answers.In addition, teachers need to submit their works in the "Teaching Design Reflection" plate with learned knowledge application in reality.
Experts collect required resources and implement the teaching according to the teaching plan design.Related technical personnel help shoot video, then check whether there is inaccuracy.If any, they need to shoot again.If not, they can begin editing and processing.At the beginning, the teaching expert will introduce the main content of the micro-course and the head will be show.The content is presented via PPT.Due to the limited screen space, the PPT will be switched to full screen when the expert begins explaining the details to make sure that teachers are able to see the learning content clearly and decrease the interference of other superfluous information.In the micro-course, there is soothing background music when reading teaching plans or cases, and the content switching is at a medium speed.Teachers whose reading speed is slower can pause it, then continue after finishing a paragraph, or download the reading materials under the video window to read.At the end of the video, there are some questions about the subject.Teachers can download related activities and exercise documents at the "Homework" and "Teaching activities" as well as PPT at the "Teaching PPT" to review and summarize.The teaching expert appears to prompt the end of the micro-course.All resources after completed and checked will be uploaded to the training platform, then teachers can log in and study.
In the learning process, the system will record teachers' learning progress.Teaching administrators will regularly publish notifications to warn teachers to pay attention to the learning progress, earned credits and getting online to participate in teaching activities and remind experts to announce practice and Q & A activities of the topic.Meanwhile, they will manage the whole learning process.
Teachers who participate in the training should evaluate after learning.The main ways include posting on the "Course BBS" and submitting "Training Logs".At the same time, the tutors also reflect and summarize the training through the "Coaching Experience".Teaching experts make further comprehensive reflection on the design of the micro-course, tune and optimize it according to teachers' feedback.

Conclusion
As a brand new teaching form, micro-course whose design, development and application are unlike that of traditional course has a certain degree of innovation.Combining micro-course with primary and secondary teacher training is a bold attempt of micro-course application.Therefore, we made a relatively deep exploration of the micro-course design for teacher training.We construct the primary and secondary teacher training oriented micro-course design mode, and take a series of micro-courses "Tutoring Teaching in the Multimedia Environment" in "National Training Program (2014)"-rural primary and secondary teachers distance training program in Guizhou province as an example to verified the feasibility.
