The Difficulties And Countermeasures For Wenzhou Ordinary High School Students Learning Algorithm

Zhejiang Province, beginning in 2006 to implement the new curriculum, the algorithm as a new curriculum in the content. However, the author, through a questionnaire survey and interviews found that the current high school math teacher in-service algorithm and the algorithm of awareness and preparation of teaching less than ideal circumstances, the teaching of algorithms, there are many confused. Accompanied by confusion teachers, students also study the existence of algorithm for all kinds of questions.In this paper, the use of a questionnaire survey and interviews of the method of middle school students Wenzhou general learning algorithm to try to answer the following questions:1st investigate the concept of teacher-student understanding of the algorithm2nd algorithm for teaching teachers to investigate the problems and confusion3rd High school students explore the general algorithm for a concrete manifestation of learning difficulties and their root causes.4thalgorithm for high-sophomore studying countermeasures difficult.Through questionnaires and interviews , teachers found that they have problems and confusion in the teaching:1stMost teachers still in doubt as to that algorithm put into the middle schoolmath textbooks.2nd Teachers are lack of he algorithm of teaching knowledge and psychologicalpreparation.3rdDo not understand the arrangement of the part of the contents of textbooks.4th Lack of curriculum resources and training not in place.Algorithm is a method of teaching the essence of thinking, feeling algorithm thinking things that can not be achieved overnight, this algorithm has led to the problem that students would have difficulty learning process.Through student questionnaires and test volume analysis algorithm to be students with learning difficulties have a concrete manifestation of the following:(1) To understand the concept of algorithm(2) To design the algorithm which contains the conditions and the cycle structure(3) To understand the conditional statements and loop(4) To transform these three algorithmsCombined with interrelated theory, taking into account the characteristics of student learning and curriculum, there are many reasons to explain difficulties of students learning algorithm, both subjective and objective reasons:(1) internal factors: Including personal interest in learning, study habits,the purpose of study, the learning attitude,the unstable basic knowledge ; lack of the necessary self-learning ability and test ability; the low efficiency of studying inside and outside the classroom.(2)external factors:Including the characteristics of their own curriculum;the teachers'teachingCombined with difficulties of students learning algorithm, classified the type of students with learning difficulties:(1)temporary difficulties,(2)Learning difficulties(3)difficulties in studying power(4)difficulties in the overall studyHaving analysed the causes of difficulties of students learning algorithm, the type of division, as well as understanding the characteristics of students,I put forward some suggestios for students to overcome difficulties in learning algorithm.(1)Student's own point of view:1stAttributed to training2nd Learn motivation and maintain3rd Recognize the importance of learning algorithm4thTo acquire a certain amount of learning methods5th Master "algorithm" problem-solving methods(2)Materials point of view1stTeaching materials should be made for all students2nd Teaching materials for students should be close to their actuality(3)Teacher's own request(4)Teaching strategies.1st to determine the appropriate goals and methods of teaching2nd Try our best to help students to remove the mysterious and fearful attitude towards the concept and expression of algorithm3rdPay attention to the actual operation and algorithm idea and less on the concept of entanglement.4thFocus on the creation of situations to prevent the parachute-style teaching.5thBetter control the progress and the difficulty and do a good job in feeling communication.6thPlease focus on the typical algorithm teaching while selecting teaching examples.7thPay attention to exercise and contact between the sample questions. 8thEmphasis on a combination of imitation and innovation 9thGeneral knowledge of the attention with other, often to consolidate 10thEmphasis on the optimization and adaptation algorithms. 11th The use of interdisciplinary teaching collaborationThis thesis is to explain the causes of the difficulties that students study algorithm , to be analyzed in depth yet, the response of the teaching is limited, the future need to go through the test of practice. For all-round development of students, in order to improve the overall quality of students, I believe that the education system should be appropriate to do, the appropriate reform: teaching in math, the teacher should also create conditions for students to deepen their knowledge and understanding of the algorithm.
