The first volume of the seventh grade art book courseware

Excellent courseware must fully reflect the teaching ideas of professors, otherwise there is no difference between ordinary teachers and famous teachers, and there is no difference between teachers and projectionists. Next, I will bring you the courseware of the first volume of the seventh grade art book for reference only, hoping to help you.

The first volume of the seventh grade art book courseware

Teaching objectives:

1, to understand the basic proportion of human body and its changes in different postures.

2. Learn the basic method of depicting task dynamics with simple lines and the general steps of character sketch.

3. Perceive the harmonious beauty of human body structure and the dynamic beauty of human body through the sketch practice of the figure's whole body posture.

1, guide the new lesson.

Campus life is rich and colorful, and the partners on campus are the people we are most familiar with. Today, we will come to Unit 2 "Colorful Study Life-Campus Friends".

2. Development stage:

(1) Study the proportion of human body in different postures.

A, use the proportion diagram of human body to guide students to measure the approximate proportion of human body in various postures.

Question 1: The partners on campus are our classmates and the people we are most familiar with. So who can tell us what different gestures students have on weekdays? We are the most perfect body, our combination is symmetrical and harmonious, and there is a proper structural relationship between our head, trunk and limbs. So, what's the difference in the proportion of people in different postures? Let's measure it ourselves, and you'll find the result. The human body has many different postures. Now we mainly test these four postures. "(scale diagram showing four postures of human body)

The measurement method is to measure vertically from head to toe according to the length of human head, and record the length of several heads.

Group measurement: one group and two groups measure the standing posture; Three groups sit on stools in a sitting position; In the sitting posture test, four groups sat on the floor; Five groups and six groups measured kneeling posture. Local proportion of seven or eight groups of words. When measuring, each group should have a division of labor: those who measure, those who are measured, those who record, those who observe and those who report. The students to be measured must stand up straight and look straight ahead when measuring.

B, students report the measurement results, and guide students to summarize the general law of human body proportion.

Through your measurement, we get roughly similar results, but not exactly the same, but different, which is normal. Because there are differences in the speed of physical development of different people, some are fast and some are slow; There are some differences between different races and genders. Now let's observe these data, and you will find the general law of human body proportion:

Standing about 7 heads long; Sitting about five and a half heads long; Sitting on the floor is about three and a half heads long; Kneeling posture is about four and a half heads long.

The upper body length is 3, the lower body length is 4, the hand length is 2/3, the upper arm length is 4/3, the forearm length is 1 head, and the foot length is 1 head.

(2) How to master the dynamics and center of gravity of the characters.

A. transition. (Guide the students to observe the legend of the textbook: the contrast diagram of the changes of scapular belt and pelvic belt)

Standing posture and sitting posture represent the shape of the human body when it is relatively static, but the actions of some characters change greatly in real life. In painting, do you think it is easier to draw a relatively static body or a moving body?

Let's take a look at the two postures in this picture and see what is the difference between the shoulder strap and the pelvis when the human body is upright.

Conclusion: When the human body is upright, the shoulder strap and pelvic strap are horizontal and symmetrical about the center line, so it is easy to draw. In the active human body, the shoulder girdle and pelvic girdle are inclined in the opposite direction, and the left and right are asymmetrical, so it is difficult to draw them. There is a small door inside. As long as you master the center of gravity, center of gravity line and dynamic line of human body shape, you will feel relaxed.

Question 2: How to master the dynamics and center of gravity of the characters? "

Center of gravity and center of gravity line. Put the picture first, then put the concept. )

Concept of center of gravity: the balance of human body depends on the stability of center of gravity, which refers to the center of gravity of objects (the center of gravity of human body is roughly above and below navel).

② The concept of barycentric line: barycentric line is a vertical line leading to the ground through the barycenter of human body. "

③ Feedback exercise: Each group sends out a slide of human body with different postures, so that students can find out the center of gravity and draw the center of gravity line after discussion, and finally show and comment on the projection.

In the exam, each group will give you a figure with different postures. Let's discuss and find out the center of gravity and draw the center of gravity line. After painting, ask a classmate to show it to everyone, and compare the students in that group to find the right one and draw well.

C, dynamic line

① Imitate the action and see who imitates it best. Show a slide with only a dynamic circuit diagram. All the students stand up and imitate the action together.

Thinking that this picture has only a few simple lines, why can everyone imitate it so accurately? This is because these simple lines are the main lines that show the general trend of human movement, which we call dynamic lines. As long as we master the dynamic lines, it is easy to show the moving human form. Let's analyze the changes in the moving line together.

Ask a student to do an action to guide students to analyze the changes of dynamic lines (or to guide students to observe dynamic line charts).

Please come up and make an action at will. Now please observe this classmate's movements. Let's analyze the changes in the moving line. First of all, let's look at the head dynamics, which is determined by the lines from the top to the neck; Look at the trunk dynamics, determined by the lines from the chest to the buttocks; Finally, look at the dynamics of the limbs, which is determined by the long line close to the garment surface. In this way, the dynamic lines of the head, trunk and limbs constitute the overall dynamic image of the characters. In a word, the lines of the spine and limbs are often the dynamic lines of the human body. You can ask a classmate to do an action casually and let other students come up and point out his dynamic line. )

(3) Sketch steps: ① Dynamic lines ② Large drawings ③ Deep (clothes pleats) ④ Complete.

Please come up and make a shot put. Please observe carefully and say the steps.

(4) Students copy and practice the teacher's patrol guidance. (Copy the pictures in the book)

(5) homework presentation and evaluation

A, students evaluate each other, and each group chooses several good works to show in front of the podium.

B, the teacher comments on the work and points out the advantages and disadvantages.

After-school development:

(1) Do some sketch exercises of campus life at any time, on the one hand, consolidate the knowledge and skills learned in this class, on the other hand, collect and accumulate materials for future creation.

(2) Using the knowledge of human body proportion and the method of expressing character dynamics, practice drawing family members or characters in the community with lines. In addition to drawing static postures, you can also try to practice drawing dynamic sketches of people.
