This is really worrying. AdamLashinsky, a senior freelance editor of Fortune magazine, also said that some people who have worked for Apple believe that,
Apple employees are embarrassed by Siri's premature launch.
At present, the settlement of $60 million obtained by Shenzhen Proview from Apple is kept by the relevant court.
Language in Chinese classroom evaluation
At the same time, the competition is becoming more and more fierce. I prefer iOS to Android. I think Windows and iOS are basically tied. But there must be many people who disagree with this statement. This is because these three mobile platforms are comparable, and none of them is in an absolute leading position. Their functional advantages are very weak. These three platforms are doing the same thing in almost the same way. Three years ago, if you bought any smart phone other than iPhone, you would be full of complaints, but now it is not what it used to be.
2. Record and reflection on the evaluation of the second grade Chinese. At the beginning of the second grade Chinese "Boulevard Pass", the junior middle school Chinese team listened to a lecture given by Mr. Heng, who taught the text "Boulevard Pass" in the second grade. The evaluation and reflection are as follows: Teacher Yao: 1, the lead-in design of this lesson is plain but effective.
The teacher asked the students to recite Peach Blossom Spring and introduced it into classroom teaching, which not only paved the way for learning new lessons, but also strengthened the accumulation of knowledge. What kind of society is "Datong" in Avenue Tong? As the starting point of this course, it has played a very good role in stimulating interest, and it should be said that this introduction is relatively successful.
2. The teacher set six questions for this class. Before class, students are asked to group the preview results on the blackboard. From the perspective of checking the preview effect and helping students understand the content, this link should be arranged reasonably, so as to cultivate students' ability of self-study, writing and problem solving. Discussion: When students state their answers, they just follow the script.
If we consider letting other groups express their opinions and discuss, it may activate the classroom and students' thinking. Teacher Xie: By designing six questions, the key points are prominent, and the knowledge points are put in place, teachers can guide reading in time, but students make less noise when presenting.
Teacher Liu: This course focuses on the connection between old and new knowledge. The classroom structure is complete and the knowledge points are basically put in place. The disadvantage is that the teacher's lecture voice is not very loud, students do not actively participate in the classroom, and the classroom atmosphere is rather dull. Teacher Niu: The teacher's thinking is clear and his speech speed is moderate, which gives students enough room for thinking. However, the display of students needs further emphasis and guidance from teachers, so that students who display nature and generosity can become role models.
Teacher Jin: Compared with Peach Blossom Garden, the problem design in this class is from easy to difficult, which helps students to understand the social characteristics of "Great Harmony". This article is written in classical Chinese, which needs to be read more. Students can express it through various reading forms, and feel, comprehend and appreciate it in reading.
Teacher Gong: As a Chinese teacher, Teacher Heng knows that the more open the classroom is, the better it will be for her teaching. Therefore, as a new member of Yang Ming, he dares to emancipate his mind and boldly try a new classroom teaching model. His strong sense of social responsibility and professionalism made me respect him. An open classroom is a classroom of humanity and democracy. It needs everyone to participate and have something to say. The right to speak in the classroom belongs to the students, and the leading role in the classroom belongs to the students.
In fact, this kind of classroom has higher requirements for teachers, which is a severe test for teachers' comprehensive quality. Teachers must keep charging and learning. Education is sacred and arduous, which requires constant efforts and exploration by all our educators. As the saying goes, "explore a new road with painstaking efforts, and you will see gold only after blowing out the yellow sand." I believe that if we have the courage and spirit of Mr. Heng to try boldly, our education will be more and more perfect and mature.
Reflecting on the beginning of school, the school organizes all teachers to learn the theory of teaching, scientific research and educational reform; The director of the county teaching and research section was also invited to give a lecture on the theory of new curriculum reform. On September 7th, I was lucky enough to listen to the students' demonstration class: novel classroom mode, warm classroom atmosphere and witty teaching ... which was well received by teachers and attracted me deeply.
During the period, I also listened to other teachers' classes, which was very enlightening. Therefore, I would like to take the opportunity of this lecture to try this new classroom model and ask my colleagues for advice.
A Passage to the Avenue is a short and pithy theoretical classical Chinese. It is difficult for junior high school students to understand thoroughly.
But I think it's a little difficult, just to give myself and my classmates a good exercise opportunity. Therefore, according to the teaching progress, use this article to attend classes.
Students are required to preview the text by self-study in the morning before class. Solve the problems of pronunciation and word meaning by yourself, and master the main idea of the text by combining the text notes.
And arranged the discussion questions of each group. Pay attention to group autonomy, cooperation and discussion.
Combine reading, discussion and guidance to organize the class. Classroom activities focus on students' independent discussion and inquiry.
In class, the students' discussion was not as enthusiastic as I thought, and some groups were obviously unprepared and their answers were too simple. Two of the six groups were well prepared and answered comprehensively, and their own ideas were also integrated into them, with good results.
There are two groups whose answers are more accurate: 62616964757a68696416fe4b893e5b19E313333303338, which did not arouse the objections of other students. Of course, it can't cause discussion, and it seems dull.
The answer of the first group is relatively simple. It has aroused the discussion of the students, and the students who make up the lessons can make improvements from different angles, forming a good discussion atmosphere.
It can be said that there are gains and losses. Review the whole class carefully.
I believe that although this course has completed the pre-set classroom teaching tasks, there are still many places worthy of improvement and improvement. 1, students are not prepared enough before class, so we must carefully organize the preparation before class.
Judging from the students' discussion, some groups have not discussed enough, and the results of the discussion are relatively simple and the conclusions are not comprehensive and in-depth. 2. Students are not enough to adapt to this classroom mode.
When some groups show the results of group discussion, their voices are too low, and even some people are at a loss and the classroom links are unfamiliar. It is necessary to participate in and exercise regularly in order to make continuous progress.
3. Teachers' ability to control the classroom should be improved. Because I don't know much about this classroom model, I don't have much contact.
Not familiar with the students' situation, not fully aware of the differences between individuals and classes. When organizing students to preview the discussion, it is not targeted.
Comments on students are also not in place. Did not create an active and smart classroom atmosphere.
These are my own superficial thoughts on this course, and I hope to get your comments.
3. Listening to the revision of ancient poetry "Dangzhou Guazhou" is a text of primary school Chinese. According to the new curriculum standard, Mr. Wang guides students to participate in Chinese practice of reading, speaking, reciting and writing, which embodies three points.
1. Students' dominant position has been implemented. The subjective position of students is determined by the nature of the teaching process. Learning is the internal cause, teaching is the external cause, and teaching can only work through learning.
Only by respecting students' dominant position, giving them the right to learn automatically and letting them consciously devote themselves to learning can we ensure the implementation of their dominant position. This class has made efforts in three aspects.
First, ensure time, avoid word-for-word combing and analysis, and save time for students to read and write more; The second is to guide students to experience the joy of success in learning practice and master learning methods; Third, teachers treat students equally. At the beginning of the class, the students agreed on the learning methods. Let students learn in class, pay attention to the cultivation of good habits, and leave students with a broad space for learning and exploration after class.
2. Facing all and focusing on development. Teachers respect every student, let the whole class have the opportunity to show, and let students choose the learning content and methods that suit them. Students can learn by clicking on courseware materials in class, and go home to learn by floppy disk, which connects classroom and extracurricular activities, expands the learning space and provides a good platform for students' all-round development.
3. The content of ideological education has been implemented. This class tries to understand the content through students' Chinese practice, and initially perceive the richness of the motherland's cultural heritage in the extension, and then cultivate their feelings of loving the motherland's language and excellent culture.
4. How to evaluate junior high school Chinese papers? 1. The concept of class evaluation is to judge the activities of teachers and students in classroom teaching and the changes caused by these activities against the classroom teaching objectives.
Classroom evaluation is a regular activity in teaching, scientific research and teaching. Colleagues learn from each other and discuss and evaluate classes together. There are school leaders' evaluation of diagnosis and examination; There are also high-level expert appraisal or class evaluation and so on. The purpose of evaluation is not to prove, but to improve.
Second, the significance of class evaluation can mobilize teachers' teaching enthusiasm and initiative, help and guide teachers to constantly sum up teaching experience, improve the level of education and teaching, and enhance teachers' educational and teaching literacy; Promote teachers to improve teaching practice, make teachers obtain information through multiple channels, constantly improve teaching level, change teachers' educational concepts, urge teachers to conduct lively teaching, and gradually form their own unique teaching style in the teaching process. Third, the principle of class evaluation 1. Class evaluation should adhere to "student-oriented development" and proceed from the needs of students' all-round development.
The core idea of the curriculum reform of basic education is "student development-oriented". Curriculum evaluation should start from the needs of students' all-round development, pay attention to students' learning status and emotional experience, pay attention to the embodiment of students' dominant position and play a leading role in the teaching process, emphasize respect for students' individuality and individuality, encourage discovery, inquiry and questioning, and cultivate students' innovative spirit and practical ability.
2. Classroom evaluation should be based on the diagnosis and correct orientation of teaching. Classroom teaching is a complete process of preparation, implementation and goal achievement, and it is a complex and changeable system. In order to fully reflect this process, quite a few factors need to be investigated.
A correct evaluation of a class should not only focus on the whole process of classroom teaching, but also not cover everything. We should highlight the investigation of the indispensable basic elements of classroom teaching in quality education, so as to make targeted diagnosis and correct guidance in evaluation. 3. The evaluation of classes should adhere to the combination of teaching evaluation and learning evaluation, focusing on "learning evaluation".
The main body of classroom teaching is students, and the implementation of teaching objectives is ultimately reflected in the learning process of students. Classroom teaching evaluation should change the traditional phenomenon of "teaching evaluation" and shift the focus of evaluation to "learning evaluation", so as to promote teachers to change their ideas and improve teaching.
It is necessary to shift the focus of class evaluation from teachers' knowledge transfer to students' effective learning direction, and to how to teach students in accordance with their aptitude. How to turn excessive unified teaching into a classroom with the main activities of guiding students to study and discuss in groups and unified answering guidance, and into a classroom that combines appropriate unified explanation with guiding students to study independently or choose freely. Change the focus of classroom evaluation: the evaluation of classroom teaching should not only focus on the quality and effect of students' learning, especially the scores of students' academic evaluation, but should pay more attention to whether teachers have effectively created an environment and atmosphere for effective teaching activities.
4. Classroom evaluation should advocate innovation and cultivate personality. Classroom teaching has rich connotations, and the differences in subjects, students, teachers and teaching conditions make classroom teaching ever-changing.
Correctly evaluating a class hour should not only reflect the general characteristics of classroom teaching, but also advocate innovation and encourage personalized teaching.

7. How to evaluate the primary Chinese class under the new curriculum reform? The evaluation of primary school Chinese class is also called class situation analysis, which is to diagnose the teaching level and classroom teaching effect according to certain standards.
It has played a positive role in promoting teaching exchange, improving teachers' professional level and promoting classroom teaching reform. Let's discuss with colleagues how to evaluate the primary school Chinese class under the new curriculum reform.
First, the principle of class evaluation. As a serious teaching and research activity, class evaluation should follow the following five principles.
The first is the guiding principle. The purpose of class evaluation is to guide teaching and point out the clear teaching and research direction for the coach or his school.
Therefore, we should grasp the main problems and characteristics in class evaluation. The second is the principle of comprehensiveness.
Evaluators should comprehensively evaluate their own strengths or weaknesses with the help of various standards for evaluating classes. The third is the principle of analysis.
Interpreters should fully affirm and encourage their own strengths with a rigorous learning attitude and proceed from objective reality, and gently point out what their shortcomings are and what needs to be improved. The fourth is the principle of pertinence.
Different evaluation methods should be adopted for different teachers and different classes. The fifth is the principle of interaction.
The evaluation of the course should not be unified, and the teachers, teachers and reviewers should actively participate in the discussion and express their unique opinions. In an equal and democratic academic atmosphere, we should seek common ground while reserving differences, guide each other, learn from each other and improve each other.
Second, the evaluation criteria. Curriculum evaluation criteria play an important role in teaching orientation, problem diagnosis and result evaluation.
Traditional evaluation criteria greatly restrict the development of Chinese teaching in primary schools. Therefore, we must learn from and absorb many advanced ideas and successful experiences of current teaching reform, grasp the trend and track of minority language teaching reform from a strategic perspective, and strive to formulate new evaluation standards according to the new curriculum standards. I think we can try to evaluate it from the following aspects.
1, the teaching objectives are clear and specific. Teaching objectives should meet the requirements of the new curriculum standards, conform to the laws of students' physical and mental development and the teaching characteristics in this field, reflect the cultivation of good learning quality and the completion of basic objectives, and pay attention to the realization of students' developmental goals.
2. The new way of learning is fully reflected. It is necessary to fully embody students' dominant position, face all students, care for and respect middle and lower class students, and create a democratic, equal and harmonious teaching atmosphere; Activate the classroom, teachers and students actively participate in the learning process, and organically combine instrumentality and humanity.
Autonomy, cooperation, inquiry learning and necessary receptive learning complement each other; Pay attention to the guidance of learning methods and cultivate good study habits. 3. Fully implement the requirements of new curriculum standards. (1) Literacy: follow the rules of word formation of Chinese characters and pay attention to the cultural information contained in Chinese characters; Adopting various literacy methods, emphasizing the guidance and application of literacy tools; Cultivate the interest and willingness of active reading and develop good writing habits.
(2) Reading: strengthen reading comprehension and pay attention to the individualization of reading methods; Attach importance to students' unique feelings and experiences, and advocate creative reading from multiple angles; Cultivate a sense of language and pay attention to accumulation; Students' thinking and expression are diversified, and learning and application are combined; Encourage students to question and seek differences and cultivate innovative spirit. (3) Expression: encourage free expression and let go of all kinds of constraints; Try to use accumulated language materials in writing; Attach importance to the guidance of specific processes and methods; Attach importance to revision and cooperate in revision; Pay attention to children's life and emotional world.
4. The teaching method is flexible and enlightening. According to the presupposition and students' questions, the teaching process is designed, and the teaching steps are effectively adjusted according to the changes of learning situation, so as to learn and teach.
It is a real heuristic that students choose flexible and diverse teaching methods according to the teaching content. The lectures are vivid and appropriate, and the questions are enlightening.
In view of the problems and contradictions encountered by students in class, practical and effective guidance and remedial measures are taken at random. 5. Appropriate and effective teaching methods.
Choose appropriate and effective teaching methods from teaching practice, so that modern educational media can be organically combined with teaching. Teachers use audio-visual media skillfully, efficiently and effectively.
6. Teachers' professional quality is good. Good appearance and kind teaching attitude.
Putonghua teaching is normative, enlightening and instructive. The handwriting on the blackboard is accurate and neat.
Strong organizational teaching ability, good at adjusting teaching strategies according to learning situation. Effectively develop and expand Chinese learning resources, reflecting the concept of big Chinese.
7. The teaching effect is remarkable. All students actively participate in the teaching process, with high learning enthusiasm and strong interest, and the teaching tasks are well completed.
Students at different levels have gained and improved. Third, several problems that should be paid attention to in class evaluation.
1, stand tall and see far. Wonderful class evaluation should combine the relevant education and teaching theories, stand on the textbook and curriculum standards, stand on the height of current teaching, guide listeners to sum up experience and learn lessons through certain education and teaching phenomena, and reveal the essential laws of education and teaching, instead of just grasping marginal problems, such as typos and mispronouncing.
2, to put facts and reason. Instructors should be fully familiar with the content of teaching materials and the requirements of curriculum standards before class evaluation, record the teaching process in detail when attending classes, write down random thoughts in the form of comments, and sort out and summarize them in time.
It is convenient to point out which link is good and where it is good when evaluating classes; What links have problems and their causes, and how to improve them. To convince people.
3, to reflect the teacher-oriented. In the new tide of curriculum reform, both teaching researchers and teaching leaders should become the service providers and cooperators of front-line teachers' education and teaching.
Therefore, in addition to attending classes, we should also pay attention to learning from them. Teachers' creative work should be respected, even if there are deviations in the classroom, don't criticize and blame too much.
According to different people and different classes, the reviewers should determine the focus and methods of class evaluation. It varies from person to person.
For new teachers, the focus of class evaluation should be on the basic ideas of preparing lessons and attending classes, whether the basic teaching skills are solid or not, and guiding and motivating them to get on the right track as soon as possible; For the backbone teachers, we should fully tap the advantages, comprehensively and deeply point out the existing problems and point out the direction for future development. Every class is different.
The nature of the class is different, and the emphasis and method of evaluating the class are also different. Ordinary classes can be evaluated by grasping the corresponding standards formulated; Special seminars can focus on special academic research: the focus of observation class is to appreciate the advantages of class and popularize teaching and research experience.
4. Pay attention to language skills. The attitude of class evaluation should be peaceful, the language should be colloquial and simple, and the quoted famous sentences of education and teaching should be explained in detail in combination with specific teaching to avoid obscure language.
Because of the coach.
