What are the advantages of individualized teaching and what are the characteristics of individual te

1. Advantages of immobilized cells.

1. Compared to free cells.

Immobilized cell fermentation has the following advantages over cell-free cell fermentation:

1) Immobilized cells can change microbial fermentation to a continuous enzymatic reaction.

2) higher cell concentrations can be obtained;

3) cells can be reused;

4) At high dilution rate, there will be no elution phenomenon;

5) High yield per unit volume;

6) improve genetic stability;

7) Cells are not affected by shear effects.

8) The content of bacteria in the fermentation broth is small, which is conducive to the separation and purification of the product.

2. Compared to immobilized enzymes.

Immobilized cells have the following advantages over immobilized enzymes:

1) The procedure of extracting enzymes from broken cells is eliminated.

2) The stability of the enzyme in the cell is high, and the loss of enzyme activity after immobilization of intact cells is less.

3) The cost of immobilized cell preparation is lower than that of immobilized enzymes.

4) No need for coenzyme regeneration.

2. Disadvantages of immobilized cells.

While immobilized cells have many of the advantages mentioned above, they also have disadvantages, which are manifested in:

1. Only intracellular enzymes can be utilized;

2. The cell membrane, cell wall and carrier all have diffusion restriction effects;

3. The pore size of the carrier affects the permeability of the polymer substrate;

4. There may be side effects.

Individualized Teaching: Teaching methods designed to suit the interests of individual students.

Individual teaching is to adapt to the individual differences of students and develop students' personalities. It requires teachers to reorganize and adjust the various factors and links involved in teaching based on the individual differences of students.

Individual teaching can cultivate people's self-survival ability and promote the comprehensive and harmonious development of people's personality, which is in line with the trend of contemporary education. From the perspective of attaching importance to individual development, individualized teaching is equal educational opportunities in the true sense.

Individual teaching features are:

Individual teaching pays attention to individual differences and promotes the comprehensive and harmonious development of personality is the common trend of education reform in the world, and the UNESCO report "Learning to Survive" points out that human self-survival ability should be cultivated, and the comprehensive and harmonious development of human personality should be promoted, and they should be regarded as the trend of contemporary education.

The Outline of the Reform of the Basic Education Curriculum requires: "Teachers should respect the personality of students, pay attention to individual differences, meet the learning needs of different students, create an educational environment that can guide students' active participation, and stimulate students' enthusiasm for learning."

Contents:

In the course of classroom teaching, no teacher can guarantee that more than 40 students will be able to listen to him from beginning to end, and at the same time, each student can only be able to carry out learning activities, which can only be achieved by using individualized teaching.

Teachers should adapt the teaching content to the different requirements of different students, divide different levels in depth, and use different ways in the presentation of teaching content, so as to improve students' participation in the classroom teaching process.

The above content refers to Encyclopedia - Individual Teaching.

Confucius put forward the idea of "teaching students according to their aptitude" very early on, that is, the meaning of individual education. Education is based on the personality or hobbies of the person being educated. For example, if he has poor receptivity, you should be more patient and educated; If you are receptive, you can impart more knowledge, and the scope can be extensive.

Individualized Teaching: Teaching methods designed to suit the interests of individual students.

Individualised teaching is a teaching method designed to suit the needs, interests, abilities and learning pace of individual students. Individualized teaching does not mean learning alone. When the same teaching materials and teaching methods cannot be adapted to the different levels of students in class teaching, teachers should design different lesson plans in order to take into account individual abilities, interests, needs and possible difficulties encountered in the teaching process.

It is different from "individual teaching", which is only a "one-to-one" teaching implementation form, which may or may not be individualized teaching, and the key lies in whether it is a specially designed teaching plan to meet the needs of the student's ability. Individualized teaching includes three elements and has four characteristics, and its teaching mode mainly includes procedural teaching, mastery learning, independent learning, adaptive teaching and individual tutoring.

The role of individualized education.

Individualized education is conducive to the overall improvement of geography literacy of middle school students, which is an important development direction of the new curriculum reform. The wide application of modern educational technology provides the possibility for middle school geography teachers to realize individualized education.

Teachers can use computers, mobile phones, networks, etc. to supervise and guide students' learning throughout the process, and give students individualized suggestions. In an individualized education environment, students will learn more easily and happily, and teaching will be more effective.

Individualized teaching is to adapt to the individual differences of students, the development of students' personality is a form of teaching, its essence is to take the characteristics of students' physical and mental development, to take the development of students, to adapt to the characteristics of the teaching methods for teaching, the core is to let each student's personality to be fully developed, no student left behind.

Element 1: Individual diagnosis of learning ability: Adopt multiple assessment methods, using objective tests, curriculum-based assessments, observations, conversations, data file review, etc., to explore students' learning strengths and weaknesses and current achievement levels.

2. Individual design and provision of teaching materials: design teaching materials and teaching methods according to the results of evaluation and diagnosis.

3. Individual performance evaluation: multiple evaluation methods must be adopted, and the evaluation method must be determined according to whether the teaching objectives are achieved to meet the needs of students' learning styles.

Individualized Teaching: Teaching methods designed to suit the interests of individual students.

Traditional individual teaching has a long history and cultural background, and has developed relatively mature in many aspects. At present, the two individualized teaching models are applied to each school and have achieved certain results. A comparative analysis of the two teaching modes shows that there are similarities and differences between the two.

Advantages of traditional individualized teaching.

Teaching efficiency is high. In traditional individualized teaching, teachers can provide individualized tutoring to multiple students at the same time, which significantly improves teaching efficiency. As long as the teacher observes the students carefully, they can correctly analyze the teaching methods suitable for the students, and if they can be scientifically classified and taught according to their aptitude, the efficiency of the classroom will be guaranteed, and the students will make certain progress.

Disadvantages of traditional individualized education.

The quality of teaching varies. In the traditional individualized teaching, the teaching ability of teachers is uneven due to the influence of factors such as region, economic level, and teacher strength. Some teachers are not even able to carry out individualized teaching and teach students according to their aptitude, which greatly reduces the quality of teaching.

Students are not highly motivated. In traditional individualized teaching, the teacher is the main body of teaching, and the students' initiative and creativity are low, and most of them are only passive recipients. In the long run, the classroom atmosphere will not be active, and students' interest in learning will be reduced.

Advantages of online individualized education.

Raise student interest. The online individualized teaching will open the human-computer interaction mode, which can express the boring knowledge in a vivid form, improve students' interest in learning, and facilitate students to grasp the learning content more firmly. It can maximize the use of various teaching resources on the network, concentrate excellent teachers and courseware, and carry out large-scale teaching.

Disadvantages of online individualized education.

Not suitable for students with poor self-control. Students with poor self-control need teachers to supervise and teach, and in online individualized teaching, teachers and students cannot interact with each other, so supervision and inspection cannot be carried out. As a result, the quality of teaching is poor, and students are lazy.

Traditional individualized teaching is more targeted, you can understand the child's learning situation in real time, learn the weak points, the network individualized teaching is more convenient, the field of contact is wider, and the students choose a wider range of teachers, but it is not easy to grasp the latest learning situation of students.

The group is different, the teaching scale is different, the teaching content is different, the teaching form is different, the advantage is that it can improve the level of education for the whole people, the disadvantage is that there is no way to teach according to aptitude, there is no way to monitor the learning situation of children.

Individualized teaching refers to a teaching strategy that allows students to learn at their own level and pace. Individualized teaching generally includes the following steps:

Diagnosis of the student's initial academic level or lack of learning;

provide a one-to-one correspondence between the teacher and the student or the machine and the student;

Structured and structured teaching materials are followed by drills and exercises, which is the way in which individualized teaching materials are organized.

Allowing students to move forward at their own pace is the basic and most striking feature of individualized instruction.

A common disadvantage of traditional teaching is the difficulty of adapting to the individual differences of students. Since the 20s of the 20th century, psychologists have begun to look for teaching methods that can adapt to the needs and characteristics of individual students, especially since the 70s of the 20th century, individualized teaching has become an eye-catching field of teaching reform and psychological research.

Advantages of Individualized Teaching:

1. The educated can choose the content and time of learning according to their own needs and conditions: it is not bound by time and place. Through modern educational methods such as television, Guanghui dubbing, audio tapes, records, movies, videos, libraries and data centers with modern equipment, and various scumbag front beam fingers are used to teach from morning to night.

2. The main purpose of individual learning is to improve knowledge and skills and solve practical problems in the work: diplomas and grading are not considered.

3. There is no restriction on the age of the educated: the age is relaxed.
