The following is a teaching plan for the third year of high school mathematics: ##1. Teaching objectives 1. ** Knowledge and Skill Target ** - Students will be able to understand the concepts of relationships, regressions, and scatter plots. - Proficient in drawing scatter plots, able to judge the relationship between variables (positive or negative) based on scatter plots. - Able to use formulas to solve the linear equation and explain the meaning of the coefficient in the linear equation. 2. ** Course, Method, and Target ** - Through the analysis of examples, the students 'ability to observe and analyze data was cultivated, and their ability to process data was improved. - Through the derivation process of the linear equation, the students could understand the idea of the least square method and improve their logical reasoning ability. 3. ** Emotions, attitudes, values, goals ** - It allowed students to experience the close connection between mathematics and real life, and to feel the application value of mathematics. - Cultivate students 'rigorous scientific attitude and the spirit of exploration. ##2. Difficulties in Teaching 1. ** Teaching Focus ** - Scatter chart drawing and its function. - The method to solve the linear equation. 2. ** Teaching Difficulties ** - Understanding the idea of least square method in solving the linear equation. - How to guide students to transform practical problems into linear regressions. ##3. Teaching Method Teaching method, discussion method, and inquiry method were combined. ##4. Teaching process ###(1) Introduction to the new lesson (5 minutes) 1. Show some real-life data relationships, such as height and weight, study time and grades, etc., to guide students to think about whether there is a relationship between these variables. 2. The concept of the relation was introduced, and the difference between it and the functional relation was emphasized (the functional relation was a definite relation, while the relation was a non-definite relation). ###(2) Explain the new lesson (20 minutes) 1. scatter plot - Explain the definition of a scatter chart, which is a graph that represents a set of data with two variables that are related. - Through examples, it was demonstrated how to draw a scatter chart. For example, given a group of students 'mathematics and physics scores, the scatter points were drawn on the coordinate plane. - Ask the students to make a preliminary judgment of the relationship between the variables according to the shape of the scatter chart (positive: the points are distributed from the lower left corner to the upper right corner; negative: the points are distributed from the upper left corner to the lower right corner). 2. linear regressions - How to find a straight line that can better describe the distribution of these scattered points? The concept of a straight line was introduced. - He explained the idea of the least squares method, which was to minimize the sum of the squares of the deviation from the sample points to the regressed line. Let the equation of the regressing line be y = a+bx, and the deviation is e_i=y_i-(a + bx_i), then the sum of the squares of the deviation is Q= 1}^{n}e_{i}^{2}= 1}^{n}(y_i - a - bx_i)^2. - Derives the calculation formulas of the linear regressions (b) and (a)(can be derived according to the method of finding the maximum value. The detailed derivation process is omitted here), and the application conditions of the formulas are emphasized. - Give specific examples, such as knowing the production and cost data of a certain product, and lead the students to calculate the linear equation. ###(3) Class Practice (15 minutes) 1. Arrange a few exercises on drawing a scatter chart, determining the relationship, and finding a linear equation. For example, give the data of temperature and electricity consumption in a certain area, and let the students complete the relevant operations. 2. During the practice, the students could discuss with each other at the same table. The teacher would patrol and guide the students, find the students 'problems in time, and give them answers. ###(4) Class summary (5 minutes) 1. Please review the content of this lesson, including the relationship, scatter plot, the concept and solution of the linear equation, etc. 2. The teacher supplemented and improved the students 'answers, emphasizing key knowledge and error-prone points, such as accurately calculating the data such as <<<sum_{i = 1}^{n}x_i>>,<<sum_{i = 1}^{n}y_i>>, etc. when solving the linear equation. ###(5) Assignment (5 minutes) 1. Students were required to complete the relevant exercises in the textbook to consolidate their knowledge of linear regressions. 2. Students were given an extended assignment to look for a relevant relationship in their lives, collect data, perform a linear regress analysis, and write an analysis report. ##5. Reflection on Teaching 1. ** Success ** - Through real-life examples, it could arouse the students 'interest and make them feel the wide application of linear regressions in life, which would improve their enthusiasm for learning. - In the teaching process, the students were guided to participate, such as drawing scatter plots and calculating linear regressions, which cultivated the students 'hands-on ability and independent learning ability. - The arrangement of classroom exercises and assignments had a certain level, which not only consolidated the basic knowledge, but also expanded the students 'thinking. 2. ** Inadequacies ** - When explaining the idea of the least squares method, some students still had difficulty understanding it. They might need to use more examples or more intuitive animations to assist in teaching. - Due to the limited time in the classroom practice session, it was impossible to answer every student's questions in detail, which might affect the mastery of some students 'knowledge. 3. ** Modification measures ** - In the follow-up teaching, a simple animation could be created to show the process of the minimum sum of squares deviation to help students better understand. - In the classroom practice session, group cooperative learning could be added to allow students to help each other and improve together. At the same time, teachers could have more time to guide individual students. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There was an eight-step creative template writing method for high school English. First, focus on the emotions, especially the negative emotions. Then, further explain the relevant details. Then, the transition section can describe personal efforts or external factors. Finally, the turning point section shows that things seem to have turned around, and the characters are hopeful and relieved. For junior high school English essay continuation, if it was a narrative essay, it would usually lead to the topic, briefly summarize the incident, then describe the incident and the outcome, and finally summarize the full text and express their own views. There was also a template for the college entrance examination's English post-reading questions. For example, according to the content of the materials given and the beginning of the paragraph, write two more sentences to make the article complete, and pay attention to the requirements such as the number of words to write. In his usual study and exam questions, he could refer to the model essay written after reading to summarize his thoughts. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Here are some of the lyrics of the song "To Myself": ** 1. Lyric of 'To Myself' by Lai Nanjing ** I will always be tainted by tears in a moment The story is mediocre, but it triggers the heart and liver Touched by it, I'm covered in wounds So unforgettable There's always a road that has been through vicissitudes In the wind and rain, we still insist on expanding our territory I dare not stop, I dare to face adversity bravely I only wish that I won't run around for the rest of my life A good wine is no match for a cup of home-brewed wine Although the home-brewed wine is clear, it can still be fragrant The full moon is hard to round, only tears To myself becoming stronger in the future Although the beauty of the world is endless, the years are like frost Although life is short, it can still be pieced together with light No matter how prosperous the city is, it can't accommodate the soul To myself when I return home in glory ** 2. The exact printed version of the lyrics of Long Meizi's "A Toast to Myself" has not been found. We can only know that the song is full of inspirational feelings. ** ** 3. Jiang Hailong (Nanfeng)'To Brothers To Myself' lyrics (Verse)** Even though we rarely contacted each other, we still stayed by each other's side. There are too many difficulties on the road of life, and you are always there to shelter us from the wind and rain. Every time they met for a short period of time, it would always be difficult for them to leave. Let this cup of wine replace the endless affectionate words. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
