Getting Started learning VB break point

. Metaphor describes the common sense of our daily basic method used in the teaching process through a large number of vivid metaphor,[link widoczny dla zalogowanych], of the obscure life of abstraction is easy to understand example, students in the learning process is designed to eliminate when the fear of hardship, often to achieve a multiplier effect. For example, to explain the three elements of the object - properties, methods, and events, the book gives concrete is defined as: the nature of the property as an object, the method as the object moves, the event object as a response to external operation . This abstract definition, students in the actual learning process is difficult to distinguish what is property, what is the way, what is the case, often confusing one class down. So how to make it easier for students to understand its meaning? In fact, we can cite examples around, such as children playing with balloons the same properties, methods, and events. The properties include the balloon to see some of the properties,[link widoczny dla zalogowanych], such as its diameter and color, and other descriptive attributes of the state of the balloon,[link widoczny dla zalogowanych], such as inflation or inflation. Balloons also have inherent action, such as the method of deflation (balloon in the exhaust gas) and rising method (let the balloon fly away.) Balloons also predefined response to certain external events, such as the balloon is punctured it deflated incident response, incident response is on to let go off. The other is to explain the process-oriented theory with practice. For example, in explaining the three basic structure of the program, teachers can cite specific examples or their close related to the course content. Example 1: sequential structure. A train in a place when the speed is V = 40Km / h,[link widoczny dla zalogowanych], with acceleration a = 0.15m / s. Accelerated motion,[link widoczny dla zalogowanych], find the speed v after 2min and the distance from the starting point S. Example 2: the branch structure. Enter a student's performance, its ratings. 90 points or more as \By results, as a condition to determine the final result. Example 3: circular structure. Campus Singer Competition for the design of a rating process. 10 judges, removing a highest score, a minimum points, calculate the average points. Teachers in the teaching process to emphasize theory with practice, and guide students to find, the practical problems around them, and then design algorithms and computer programs to solve these problems. Some examples of explanations by making it easy to understand and accept students. Gradual increase in the difficulty of the program in the learning process, the program book is relatively simple, but for the initial contact with the structure design language of the students still can not fully understand and grasp, for example loop, the syntax for this statement must be explained thoroughly, the book's example is to strive for (s = 1 +2 +3 + ... ... +100) of natural numbers and procedures. Students take full advantage of this procedure at the same time, in order to deepen the understanding of the procedure, you can on the basis of the original program and increase gradually change the conditions of the comprehensive approach to improve the students programming skills. Teachers can make the original program the following modifications. (1) Find all numbers between 1 to n and (any natural number n from the keyboard.) (2) Find all the odd-numbered between 1 and 100 and (1 +3 +5 + ... ... +99). (3) Find all the even number between 1 and 100 and (2 +4 +6 + ... ... +100). Enable students to think for themselves and through the machine debugger. Applied to the first question, we should have learned earlier that the InputBox input statement, the final value of the loop by the statement from the keyboard; the second book in question and the same examples, as long as the step cycle to 2 or can; third title in the second theme based on the original statement only need to modify the loop to the initial value of loop variable (initial value is 2.) Writing programs for students and teachers to guide students to observe the sidelines some of the key points in the program changes, the integrated use of previously learned knowledge in order to further understand for ... ... next cycle. Through this series of exercises in simple terms the comprehensive programming skills so that students can be improved. The above solution appears to be a simple procedure, but do often have to spend a lot of trouble together, including the idea, writing process, debug, modify, succeed. The students in the concrete realization of the process, often the \, thinking ability improved by leaps and bounds. High school program designed primarily to train students in logical thinking ability to understand the basic idea of program design. As long as we caught in the usual teaching of the basic points, the student is granted the \2007/07 Information Technology Education l101
