2. Mind-Map Theory and Its Application in Language Acquisition
The term “mind-map” was first popularized by British popular psychology author Tony Buzan  . A mind-map is a diagram used to visually organize information. It is often created around a single concept, drawn as an image in the center of a blank page, to which associated representations of ideas such as images, words and parts of words. Major ideas are connected directly to the central concept, and other ideas branch out from these major ideas. Mind-map can be used to generate, visualize, structure, and classify ideas, and as an aid to studying and organizing information, solving problems, making decision, and writing. Mind-map have many applications in personal, family, educational, and business situations, including note-taking, brainstorming, summarizing, or sorting out a complicated idea.
Currently, researches on Mind-map mainly focus on the following four aspects: Firstly, the effectiveness. Cunningham  conducted a user study in which eighty percent students regard that “mind-map help them understand concepts and ideas in science”. Other studies also report positive effects through the use of mind-map. Farrand, Hussain, and Hennessy  found that Mind-map had limited, but significant, impact on memory recall in undergraduate students; Secondly, researches on features of mind-map. Beel and Langer  conducted a comprehensive analysis of the content of mind-map, the result of which showed that between different mind- map applications, significant differences exist related to how users create mind maps; Thirdly, researches on automatic creating of mind-map. There have been some attempts to create mind maps automatically. Brucks and Schommer  created mind maps automatically from full-text streams. Rothenberger et al.  extracted the main story of a text and presented it as mind map. And there is a patent about automatically creating sub-topics in mind maps; Finally, Pen and paper vs. computer. There are studies analyzing whether electronic mind-map- ping or pen based mind mapping is more effective.
In conclusion, mind-map is an effective method in various fields and it will bring breakthrough in language learning and teaching, especially in level of college.
The term meta-cognition literally means cognition about cognition, or more informally, thinking about thinking. Meta-cognition is defined as knowledge about cognition and control of cognition. Meta-cognition also thinks about one’s won thinking process such as study skills, memory capabilities, and the ability to monitor learning. Meta-cognition knowledge is about our own cognitive processes and our understanding of how to regulate those processes to maximize learning.
So far, in the field of education and learning, meta-cognition can be interpreted from three aspects: meta- cognitive knowledge, meta-cognitive experience, monitoring strategies. Meta-cognitive knowledge refers to cognition on the learning target; meta-cognitive experience refers to the emotional experience, including the feelings, judgment, and prediction in the course of cognition; monitoring strategies refers to the control and adjustment in the course of cognition to maximize the effect of learning. In the specific cognitive activities, the three factors are simultaneous and interrelated. Meta-cognitive knowledge is the base; meta-cognitive experience can enrich the former and meanwhile adjust the application of meta-cognitive monitoring strategies. They all promote the course of cognitive activities.
4. Current Situation of College English Acquisition
Foreign language teaching is a complicated and systematic project, including a great variety of components, for example, professors, students, teaching mode, teaching manual, test and assessment. Based on different educational theories, the mode of college English teaching can roughly be divided into three categories, to be specific, teacher-centered teaching mode, student-centered interactive teaching mode, integrated teaching mode. In addition, as the rapid development of modern science and technology, especially the widespread of Internet, scientific educational technologies has entered and are playing an important role in college English teaching. Not only are computers and projectors used in exhibiting teaching materials, but also the whole course of teaching. What’s more, the students can make full use of their spare time, learning by themselves, which is, on the one hand, corresponding with the modern concept of learning and teaching; on the other hand, emphasizing the importance of autonomic learning ability and skills.
In order to know the current situation of college English teaching and learning, the authors takes non-English major students in Yantai Nanshan University as target research group, surveying their puzzles and difficulties in the course of English learning. Through communicating with these students, the author found the existence of some inevitable problems. First, some students say “I know English is really important for the study of professional knowledge and for my future career. However, I feel frustrated by the fact that I cannot master it even though I’ve learned it for at least ten years”; Others say “I cannot communicate with native speakers freely. The more I want to say, the less I can say our”. Both indicate the embarrassing situation of College English teaching―teachers and students work hard on English teaching and learning, while the result of learning is not satisfying; Secondly, College English teaching is deeply affected by intellectualism. All teaching factors are centered with knowledge itself, including the presenting of teaching content, teaching method, and teaching mode so on and so forth. At the same time, students’ non-intellectual factors, such as attitude, views on learning, are neglected consciously and unconsciously; Finally, simplicity and stylization also block the interaction between teachers and students.
To conclude, all factors mentioned above affect the effect of college English teaching. In other word, introducing a teaching and learning method based on advanced educational concepts are essential, and the introducing of mind-map and meta-cognitive learning strategies is a favorable attempt.
5. Optimization of College English Acquisition on Basis of Mind-Map and Meta-Cognitive Learning Strategies
5.1. College English Acquisition from the Aspect of Planning Strategy and Mind-Map
Plan strategy refers to learners’ planning of learning objectives, content, time, schedule, learning strategy, so on and so forth before the start of learning activities. In autonomous learning, in the first place, students should make scientific plan and acquire corresponding executive capacity. To be specific, to allow learners to arrange learning content according to their own learning process; In the second place, students should be able to undertake corresponding learning responsibility; What’s more, teachers should assist learners to further foster and develop their independent learning strategies, and give full play of their enthusiasm and initiative. However, the fact is that in the process of autonomous learning, some learners have acquired meta-cognitive learning strategies and can apply these strategies in learning. For example, before the start of learning activities, they can make detailed schedule on learning content, timing, and target tasks. By contrary, there are still quite a few learners who learn English passively. That is, they can only carry out the learning process under teachers’ instructions without individual initiatives.
For any language acquisition activity, learners are always the main body of learning. Learners’ initiative should be fully exerted with the purpose of enhancing the application of planning strategy in the process of College English teaching. Generally speaking, it includes the following measures: On the one hand, to establish a correct concept on autonomous learning and realize creative learning, which is the premise of all learning activities; On the other hand, in order to activate learners’ internal learning motivation, the purpose and value of learning should be emphasized and external rewards should also be desalinated; To sum up, by using above methods to improve students’ planning strategy, the effect of learning can be improved greatly.
5.2. College English Acquisition from the Aspect of Monitoring Strategy and Mind-Map
Monitoring strategy refers to the learners’ active monitoring process in their learning behavior. Thus, on the basis of reflections on the monitoring result, learners can constantly adjust their learning strategies, so as to ensure the achievement of learning goals. At present, with the open network environment, network information resources and the problem of over-abundant information aroused people’s concern. Also in the course of College English learning, students are facing more kinds of information and various points of view on learning. Being lack of teachers’ guidance, supervision and management functions, students feel confused, and they need further guidance and management. However, the fact is that vast majority of students now excessively depend on external forces, such as the teacher’s guidance and constraint, although to a certain extent, they have acquired an independent way of learning. In another word, they haven’t established a strong sense of independent learning ability to solve problems.
5.3. College English Acquisition from the Aspect of Assessment Strategy and Mind-Mapping
Evaluation strategy, also called assessment strategy, refers that students can reflect and evaluate their own cognitive activities and strategies according to the relevant evaluation standards at the end of the learning activities. By applying assessment strategy, learners can timely detect problems in the process of learning, and correct the deficiencies. As the indispensable link of learning process, evaluation mechanism can ensure the learning effect and improve the efficiency of learning. Therefore, under current network background and in the process of College English teaching, students should be aware of the evaluation of online autonomous learning. The reason is that, on the one hand, learners’ learning effect is not satisfying, and they are weak in self-control. For example, they fail to finish the learning tasks, achieve learning goals, and make it impossible to make effective learning feedback and evaluation; On the other hand, the learning evaluation of this cognitive process itself is seriously enough. Therefore, teachers should guide students to form their own learning process evaluation, to combine knowledge evaluation and emotional feedback evaluation together, and to focus on the dynamic evaluation and process evaluation. In this way, learners can truly understand their own deficiency in the learning process, be able to get timely feedback and correction, and finally promote autonomous learning effect.
