If you ask an elementary school child: "Do you like painting?" I believe that the answer to the answer "like" will account for most of the answer; another question: "Do you like computers?" I believe the answer to "like" Account for more. Computer painting is a combination of computer and painting. It has the basic characteristics of traditional painting, such as lines, graphics, colors, modeling, and composition; it is convenient and easy to use, novel and unique, with rich and diverse expressions and effects, and has advantages that traditional painting cannot compare with. Teaching computer painting in elementary schools has stimulated children's interest in learning information technology, enhancing children's skills in using information technology, and at the same time improving aesthetic ability, which can lay a good foundation for future information technology teaching. There is a difference between a student's computer operation ability and drawing ability. Some students' drawing in reality may be bad, but his computer drawing is very interesting. Therefore, in the process of teaching, we should take care of every student as much as possible, mobilize students 'enthusiasm for learning and creative thinking, respect students' individual differences, and give students room to develop their potential.
In the teaching of information technology throughout the elementary school, learning about drawing can be divided into two parts:
1. King of Paintings
In the first-year learning of information technology, Jinshan King is mainly used for painting. But for the first-year children who are new to computers, the computer mouse should not be skilled enough, and they like to paint, and they have the courage to express their own emotions, but they often fail to paint. To solve these problems, we need to adopt a step-by-step process to teach, strengthen students' computer operation skills and skills, and improve their computer drawing ability.
First, start with the training of mouse operations. When the students first came into contact with the computer, they did not understand the computer and were not used to operating with the mouse, let alone drawing with the mouse. In this case, we need to design a special practice method for students, mainly to practice mouse operation, select some jigsaw puzzles, coloring games (such as spelling, coloring experts), etc. to stimulate student interest, for Computer painting is a good foundation.
Then, start with the use of tools. After students have mastered certain computer application skills, we can guide students to draw with simple line shapes. You can start from drawing lines, drawing triangles, drawing the sun, etc. from simple to complex. Arrange simple drawings according to the content of the class for students to practice, and then use the children's imagination to connect these fixed graphics with various things in life To complete the application of various tools. For example, when teaching the "Ellipse" tool, if you let students use this tool to create a painting after the introduction, although there are many materials in this aspect of life, it is not limited to what to draw. There is no prompt. Continuously superimpose circles or ellipses on the screen or complete some simple paintings such as the sun and balloons. The content is very thin. After the student's thinking has been relatively fully brewed, the teacher can guide in time to let the student think about what other objects in life are round or oval. Immediately, some students pointed out that our head was round, and some students pointed out that the body of the chick was composed of two ellipses ... The teacher showed the picture on the screen, so that the student's thinking was opened and happily. There was a discussion. Various pictures have also been born on the students' screens, such as bears, hats, caterpillars, and even beautiful sheep. This kind of teaching rhythm, which leaves behind, leaves room for students 'active thinking in time and space, enables students to overcome the dependence and inertia in thinking, exert students' subjective initiative, guide students to think positively, and passively Turn to active.
Then go on to make propositional painting creation training. When students have mastered various painting tools and have accumulated a certain amount of painting creative materials, they can carry out proper propositional painting training. Picturesque stories and illustrations of texts. It can help students to further improve their ability to create paintings, so that their painting creation has further rapid development. Because problems can be discovered and solved only during practice, and skills can only be continuously improved during practice.
When evaluating children's works of Jinshan King of Paintings, it is necessary to put forward the advantages of the works and say more about "you are awesome" and "really beautiful". The purpose of the young students in learning computer painting is not just to teach them to draw a picture, nor to train future computer painting masters, but to use it as a means to develop intelligence, cultivate creative awareness, creative talent and noble sentiment. . We need to discover the "flashing points" of students' innovation in time, take advantage of the situation, encourage students to give full play to their creativity and imagination, and encourage them to form precious artistic personality and creative literacy.
2. Drawing software
The teaching of drawing software is not independent in terms of drawing tools themselves.It has made very good latent preparations for students' future understanding and development of computers, which has played a foundation and promotion for in-depth learning and understanding of computers in the future. The role. Learning drawing can popularize computer knowledge, and cultivate students 'sentiment, and cultivate students' innovative spirit and practical ability. At the same time, students can also learn the basic knowledge of Windows system operation, such as: some common knowledge of the computer, understanding the desktop, correct posture to operate the computer, keyboard fingering, starting and exiting application software, changing the window size, skilled operation of the mouse, intelligent ABC input method, Open files, save files, print files, create your own folders, etc. Learn how to use some menu commands and shortcut keys and function keys. Such as copy (Ctrl + C), paste (Ctrl + V), Shift key, Ctrl key, Alt key. More importantly, it can cultivate students 'interest in learning, let them experience the fun of computer painting, mobilize their passion for learning, develop their inherent potential, and fully demonstrate students' creativity and imagination.
This software does not have the bright and colorful materials like Jinshan King, but only some common tools, which are easier to use. When first learning computer drawing, students can first look at some simple line drawings for copying, or give students some time to do free graffiti; when teaching computer drawing, the author generally first let students browse the various teaching knowledge points. Get in touch. According to the feedback of the students, the teacher briefly introduces the summary, and takes a little more time to teach the content that is more interesting to the students and the places that are more difficult. Students like graffiti, and graffiti is also a good way to get familiar with drawing tools, so encourage students to graffiti and be happy to watch each other. Communication between peers can make students have a deeper understanding of this software and will use it more. Handy.
Teachers sometimes feel that the use of various tools in the classroom is boring and tedious. "Drawing" tools and palettes are all marked with image legends and obvious colors. Students can see it at a glance without the teacher's explanation, and the same image can be completed with different tools and different methods. Instead, the teacher's explanation restricts the development of students 'thinking and ability, and also violates the laws of students' physical and mental development and the basic principles of education and teaching. We only need to create an environment (situation) for the students. When the children are immersed in these situations to complete the tasks given by the teacher, the teaching goals are naturally completed. For example, in the lesson "Copy and Paste" of the teaching materials of Jiangsu Province, you can introduce Sun Wukong uprooting hair and blow a lot of stories in the lesson. You can put a section of Sun Wukong uprooting hair and blow it in the lecture. A lot of videos of Sun Wukong, and then provide the pictures of Sun Wukong to the students, let the students copy and paste a lot of Sun Wukong, and then send the clouds, and finally the students also let Sun Wukong take a walk across the wind to learn "Select" "Crop" tool.
Although the basic tools of "drawing pictures" are simple, they cannot be used flexibly. The main reason is that they lack creative thinking. Therefore, when students have mastered the use of basic tools, they should cultivate students' innovative thinking and improve their information processing skills in the lectures, so that they can learn the essentials of learning, find problems, elaborate problems, and solve problems. . When teaching the text "Modify Graphics" in the first volume of the Ministry of Education, most of the students will draw from the conventional thinking and use the curve tool to draw the part of the moon. This will take a lot of time and the effect is not ideal. If the teacher directly tells the students how to draw, it may complete the teaching task in a few minutes, but the student's thinking process is not there, and his ability has not grown. Teachers should consider how to guide students to analyze, discover, and explore when organizing teaching, and finally come to use two intersecting circles to form a crescent shape, and then use the "rubber" to erase the excess part. It has cultivated students' creative thinking ability. This is to emphasize that in teaching, teachers should not teach drawing to teach "drawing pictures", and students should not learn drawing to learn "drawing pictures".
The evaluation of the drawing part can be divided into three aspects, namely foundation, skill and creation. For example, the evaluation of drawing foundation can encourage students to master the use of drawing tools and paint boxes, and the preliminary use of some menu functions to lay the foundation for drawing skills; the evaluation of drawing skills can enable students to master copy and paste and cut and paste , Custom colors, rotation, reverse color, transparent and opaque processing and other drawing skills, and further use the toolbox, paint box and menu to lay the foundation for drawing creation; the evaluation of drawing creation can further improve students' drawing level and Drawing skills enable students to connect computer applications with other disciplines, such as Chinese, fine arts, mathematics, etc., and with the reality of life, fully demonstrate students 'drawing skills, stimulate students' innovative awareness, and enhance their self-confidence.
Computer painting provides students with another kind of drawing space, which is suitable for students to learn information technology courses. Effectively carry out computer painting teaching in elementary schools, pay attention to entertaining in teaching, step by step, guide according to the situation, appreciation and evaluation, help students master simple computer operation skills, prepare for learning information technology in the future; help improve students ’ Aesthetic sense, develop their intelligence, cultivate their thinking ability and innovative spirit.
