Reflection on teaching plan of inclination angle and slope of a straight line
The following are some of the main points of teaching reflection on the angle of inclination and slope of a straight line: ** 1. Success ** 1. ** Introduction and transition of knowledge ** - When introducing the concept of inclination angle, it could be introduced by saying," Two points determine a straight line. After removing a point, countless straight lines can be made. The difference between these straight lines is the degree of inclination." This could naturally guide students to think about the concept of inclination angle. - It was reasonable to introduce the concept of straight line slope with the help of the concepts of slope angle, slope and the relationship between them learned in junior high school. It could help students transition from familiar knowledge to new knowledge. - From the idea of " two points determine a straight line, the straight line determines the inclination angle, and if the slope exists, the slope is also determined. Can the slope be calculated by any two points on the straight line?", he introduced the slope calculation formula, and set up exercises to let students discover the relationship on their own, which was helpful for the construction of knowledge. 2. ** Details ** - Pay attention to the connection between old and new knowledge, such as the concept of tilt angle and slope, and the knowledge learned before. - For a straight line with a slope of 90°, there was no such error-prone point. It could be understood by students from the essential point of view of the non-existence of the diagonal value, rather than simply a rule. When the slope exists, the relationship between the positive and negative of the slope and the range of the inclination angle is also analyzed in detail and displayed directly, which can deepen the students 'understanding of the concept. - The exercises were set according to the students 'cognitive rules, from special to ordinary, from shallow to deep. 3. ** Infiltrating the way of thinking ** - In the whole teaching process, through the combination of numbers and shapes, students can better understand the concept of inclination angle, slope and the situation where the slope does not exist when the inclination angle is 90°, so that the abstract concept becomes intuitive and easy to understand. 4. ** Overall control of the classroom ** - Focus on summary, interact with students, pay attention to students 'learning status, and help students consolidate their knowledge. - He was good at using multimedia-assisted teaching, and his teaching posture was natural and generous. His Mandarin was standard, and he could give students a good learning experience. ** 2. Inadequacies ** 1. ** Teaching experience ** - The lack of experience caused him to be too nervous in public classes or the first class, repeating the knowledge points too many times, and the time arrangement was unreasonable. For example, he spent too much time on " the existence of slope and the discussion of the positive and negative slope and the value range of the slope angle." This caused the deduction of the slope formula and the explanation of the examples to be insufficient, and even dragged on the class. Moreover, the content of the course was not finished, and the difficult points could not be highlighted and broken through. 2. ** In terms of students 'main body status ** - When emphasizing the key knowledge, the speed was too fast and the number of repetitions was too many, which did not give the students enough space to think and play. For example, in the discussion of the non-existence of the slope of a straight line with an inclination angle of 90°. - They did not pay enough attention to the individual students and did not take into account the learning needs of different students. 3. ** Introduction to class ** - Inappropriate classroom introductions would affect the teaching effect. For example, if the students simply introduced questions or paid too much attention to Descartes 'introduction method, if they did not combine the actual situation of the students with the overall grasp of the course content, it would make the students feel lost or not interested, and it might also lead to a smooth connection in the teaching process.

" It's fine if you're old, but why do you have to become a spirit?" This meant that the elderly should have the appearance of an elderly person.

They should not do anything that did not conform to their status or was unacceptable, such as deliberately bullying children, deliberately pengci, and other bad behaviors. It could also be used to describe someone or something that pursued perfection too much or was entangled in details, causing unnecessary trouble or trouble.
