As a hard-working educator, we have to write a lecture draft, with which we can improve our teaching ability quickly. So what is an excellent lecture draft? The following is a sample essay (5 selected articles) of the designed lecture notes collected by me for your reference only, hoping to help you. The designed lecture draft 1
1. Talking about teaching materials
1. Brief analysis of teaching materials:
Before learning this chapter, many students have not been exposed to the program, and they often have some wrong understandings, thinking that as long as the problems are handed over to the computer intact, the computer will solve them. The reason why the computer can solve these problems is that we set the steps to solve the problems for the computer in advance. Therefore, when we get a problem, we must first figure out what to do, then design how to do it step by step, that is, design an algorithm to solve this problem, and finally choose a suitable computer language to write programs to make the computer work and get correct results. Therefore, to solve any problem, we must design algorithms and write programs.
The topics involved in this chapter are not complicated, and the algorithm is relatively simple. Many teachers think that the knowledge points of algorithms and flowcharts involved in the section "Algorithm design for solving problems" are difficult, boring and difficult for students to understand. Therefore, the teaching content of this section is often omitted or simply talked about later. In this way, students often don't seriously consider the algorithm after getting the topic, and focus on the grammar rules and sentences of the language from the beginning. Learning programming, if you only know the grammar rules of computer language and don't know the algorithm to solve the problem, you can't make a good program. So I emphasize algorithm design when students just start to learn programming, so that students can experience the idea of algorithm, understand the position of algorithm in programming and develop good programming habits. Language is just a tool, and algorithm is the soul of design. As long as the algorithm is correct and the flow chart is correct, the program can be written in any language. The content of this section is difficult and boring, so I pay attention to giving more practical examples in the process of design teaching, combining with the knowledge of mathematics, physics and other disciplines, guiding students to pay attention to finding and discovering practical problems around them, and combining theory with practice to design algorithms. Although some common and simple examples are designed in the teaching process, the algorithm is still difficult for students to understand and master. The teaching in this section is only the beginning and enlightenment, and the requirements for students should not be too high. Through continuous and in-depth study, students' understanding will gradually deepen. Don't rush for success, you should do it step by step.
2) Teaching objectives:
Knowledge and skills:
1. Understand the basic concepts of the algorithm and the representation method of the algorithm; The algorithm can be described by flow chart.
2. Understand the basic concepts of algorithms and computer programs, and understand the basic process of computer program execution.
process and method:
1. By analyzing the problem, understanding and being familiar with the process of solving the problem clearly, the concept of algorithm is established.
2. By describing the algorithm process with flowchart, master the method of describing the algorithm with flowchart.
Emotional attitude and values:
1. Through the process of solving specific problems, we know the role and significance of the algorithm for problem solving and program design.
2, through the algorithm description, exercise the ability to analyze and solve problems, and cultivate rigorous thinking habits.
3) Analysis of important and difficult points
Learning content: Understand what an algorithm is and master the method of describing the algorithm by flow chart.
learning focus:
step by step to solve the problem;
how to describe the solution of the problem with an algorithm;
the flow chart describes the method of the algorithm.
Learning difficulties:
1. Describe the steps to solve the problem, that is, the description and representation of the algorithm;
2. The flow chart describes the algorithm;
3. Representation of program structure, determination of key conditions and their embodiment in flow chart.
second, the teaching method of speaking
1) With the help of multimedia, vividly demonstrate some algorithms to students and stimulate their interest.
2) The teacher only explains a relatively simple example, and each program structure in the station provides corresponding examples, which can cultivate students' ability of inquiry learning.
Third, the method of speaking and learning
1) Algorithms are difficult for students to understand and master, and there are many teaching contents in this class. I think it is more difficult for students to understand these contents if they fight alone. Therefore, I wonder if I can use the collective wisdom of my classmates to unite and cooperate in a competitive atmosphere to better arouse the wisdom spark of each classmate. So before class, I divided the class of 35 people into 7 groups, and participated in the discussion and thinking in groups in class. Seven groups compete with each other, and the members of the group cooperate with each other, and know how to identify and appreciate the achievements of other groups. Through this form of class, students' inquiry learning ability, team consciousness, competition consciousness and the quality of respecting others and appreciating each other are cultivated.
2) The topics selected by the students themselves, because the students know their own level best and take into account the group's points, so each student will choose the topic that he is most sure of and has a high score, thus achieving the goal that each student can try his best to master the knowledge of this lesson.
IV. Talking about the teaching process
1) Teaching ideas and teaching links
Introduction: Determination of crossing the river scheme
Concept of the algorithm
Description of the algorithm:
The teacher explained the common symbols of the flow chart and the representation methods of three program structures, and demonstrated the drawing method of the flow chart by taking "outputting the smaller value of two numbers" as an example.
students choose two questions and complete the flow chart.
flow chart of analyzing three questions.
Optimization of the algorithm
2) Teaching-assisted teaching
Multimedia demonstration animation, showing the plan of crossing the river, attracting students' attention and stimulating interest
Dynamic teaching website, supporting platform for the whole class, which can release tasks and upload homework, etc.
3) blackboard writing design
lecture draft of problem-solving algorithm design 2
1. Teaching materials
This lesson is the teaching content of Lesson 1 in the first volume of the second grade of People's Fine Arts Publishing House, and belongs to the field of "design and application". In the teaching of this class, a large number of pictures are used to show cups of various ages, uses, shapes and materials, interspersed with observations on local design intentions, to understand the relationship between design and application, and to find that many items in life are related to use when designing. At the same time, it inspires students to design cups from a practical point of view, and cultivates students' observation, analysis and design abilities.
second, the analysis of learning situation
children in this period are naive, active and curious, and a little thing can arouse their wide-ranging reverie and have strong creative vitality.
Students in lower grades have mastered the use of different materials and art tools, and have a certain understanding of the shapes and colors of things, and can express them boldly and freely with simple lines and color blocks according to their own feelings. They are very interested in beautiful things and have the ability to feel beauty initially, but their concentration time is short and their hands-on ability is weak.
Third, talk about teaching objectives
In order to better highlight the teaching content, I set the following teaching objectives according to the characteristics of teaching materials and the analysis of learning situation: Knowledge and skills objectives: Through teaching, let students know about the structure, materials and functions of various parts of the cup. Process and Method Objective: To design a personalized, practical and beautiful cup by using the knowledge. Emotional attitude and values goal: students understand design elements, infiltrate design consciousness and cultivate innovative spirit.
Fourth, talk about teaching emphases and difficulties
Based on my teaching objectives, I set the following teaching emphases and difficulties:
Emphasis: observe and analyze the design intent of each part of the cup, and understand the relationship between function and image.
difficulty: using design consciousness, design a practical and beautiful cup.
V. Speaking teaching methods
In order to better highlight the key points and break through the difficulties, I will adopt the following teaching methods to carry out teaching activities: questioning method, narration, demonstration and so on.
VI. Teaching preparation
As the saying goes, "A clever woman can't cook without rice." Good teaching preparation can improve the classroom teaching effect. To this end, I have made the following preparations: courseware, cups and other related materials.
VII. Talking about the teaching process
Starting from the teaching suggestions of the new curriculum standard, I will give full play to the role of modern educational technology, use multimedia to assist teaching, change static into dynamic, integrate sound, shape and color, provide students with vivid and intuitive observation materials, and stimulate students' initiative and enthusiasm in learning. The specific links are as follows:
(1) Introducing a new lesson
Well-designed introduction is undoubtedly a key step to the success of a class. Its purpose is to attract people's attention, so that students can participate in the activities with great interest and achieve twice the result with half the effort. To this end, I will show a disposable paper cup to guide students to perceive common items in life, feel different appearances and appreciate the elegance of the cup. This leads to my topic today: The Design of Cups.
(2) Intuitive perception
The Curriculum Standard emphasizes that the art curriculum needs to highlight the visual sense. First of all, I will use the combination of teaching method and display method to guide students to watch ancient cups and modern cup pictures, and think: "Which one do you like, and what material is it made of?" And tell me why I like it. " When the students have a preliminary perception of the cup, continue to ask: "What other cups made of materials have you seen?" Through preliminary appreciation and observation, students can feel independently, thus stimulating their interest in in-depth understanding.
Art is a subject closely related to life. Let students see the design consciousness and production level of their ancestors and feel the long history of cups by using ancient cup pictures. Guide students to contact life, recall and observe cups made of various materials in life, and initially feel the differences in materials and appearance of cups, which effectively stimulates students' enthusiasm for learning.
(3) analysis and exploration
Then, I will take a typical cup as the analysis object, so that students can understand the structure of the cup through observation and analysis, which is in line with students' cognitive level and lays the foundation for students to design the cup. Show a common cup and ask a question: "Although the materials and shapes of these cups are different, they are similar in structure. Please analyze, which parts does it consist of? "
finally, let me summarize the structure of the cup-it is composed of the cup body, the cup mouth, the cup bottom, the cup handle and the cup cover. Describe the function of each part of the cup: the cup body-holding liquid; Cup mouth-convenient for drinking water; Bottom of the cup-make the cup place smoothly; Cup handle-easy to hold the cup by hand; Cup lid-keep the liquid in the cup warm, hygienic and easy to carry. In art study, the presentation of materials can effectively broaden students' horizons. Teachers can display novel and unique cup pictures in different categories, which can better broaden students' design ideas and cultivate students' observation and imagination. The purpose of displaying multi-functional cup pictures is to effectively stimulate students' innovative thinking and make students reflect the novel and unique side of the works in the design.
(4) Demonstration and explanation
To this end, I designed such an exercise and made a cup design drawing, which includes: cup graphics, simple functional descriptions, sizes of various parts, names of articles and designers, etc., for students of different levels to choose to complete, so as to improve the efficiency of classroom work and enhance students' self-confidence in completing their homework. Through the setting of this link, students are guided to understand the relationship between design and application, which provides a strong guarantee for students to master design methods and design novel works.
(V) Practical Exhibition
Finally, I will hold an exhibition of "novel cups" design works.
1. hold a new product design conference: ask designers to show their design works and explain their design intentions. Award the best creativity award, the best function award, the best appearance award and the comprehensive award.
2. Evaluation requirements: whether you can actively participate in observation and research; Whether the design works embody the people-oriented, practical and beautiful design concept; Can you draw a design drawing that reflects your own design concept? The situation of "new product release" provides a stage for students to show themselves and guides more students to better experience the joy and success of art learning in the process of independent participation in evaluation.
(6) class summary, expansion and improvement
At the end of the course, students are guided to review the key points of this lesson in a retrospective way, and the knowledge of this lesson is summarized and sorted out, so that students can have a more systematic understanding of the knowledge of this lesson.
Finally, in order to make students improve at a higher level, I left an extended homework for students to make their own designs with plastic materials.
VIII. Lecture notes on blackboard writing design 3
First of all, let me talk about the first section: understanding of teaching materials.
When I opened the lesson "Design of Desk Lamp", two words popped up in my mind-"Fun and creative". Walking into this class, I found that this class belongs to the field of design application, and it is an art class with the characteristics of appreciation, cooperation and interaction. The purpose of this lesson is to let students find inspiration from their daily life by appreciating different creative desk lamps, and make a desk lamp with design highlights by using waste. In Lesson 1 of Book 6, The Bridge in My Hometown, students have learned to design a novel bridge. The 13th lesson of this book, The New Generation of Bottles, is to design and make a bottle from the perspective of bionics. Therefore, the course "Table Lamp Design" plays a connecting role.
Based on the above interpretation, according to the characteristics of the textbook and the actual situation of our rural fourth-grade students, I will arrange this lesson to be completed in one class. According to the new curriculum standard, it puts forward that "knowledge and skills, processes and methods, and emotional attitudes and values should be emphasized"; According to the requirements of "emphasizing the development of students' personality and advocating cooperation and inquiry", and combining with the actual situation of the students in this class, I have set the following three-dimensional goals for the teaching of this class:
knowledge goal: understanding different ideas or production methods in desk lamp design
skill goal: being able to design or make a complete desk lamp, and designing or making a unique desk lamp by drawing, cutting and winding.
emotional goal: to cultivate students' creative ability of combining aesthetics with practicality or practical ability of making desk lamps, and realize that the inspiration of design is often hidden in daily life. According to the teaching objectives of this class and the actual situation of the students in this class, I will
