Evaluation Of The High School It Knowledge Space

It is the important means to test and assess student's information technology knowledge and master the situation that the information technology of high school has an examination. A high-efficient system of test and assessment should adopt the objective and rational evaluation criterion, and should have a unifying way to test and assess students in an all-round aspect. The system should master the situation according to students' knowledge, offer for teaching of teacher and student and guide the constructive suggestion. Have it now under web-based learning environments, the paper examination of information technology shouldn't have a traditional unitary way of testing and assessing, but should have an effective way to lest and assess the information literacy of students. The paper examination should not only have an objective and standard way by testing and accessing the studies of student, but also should make a response to the situations of students comprehensively, and the same time it can provide help to the study of the days to come.I regard Knowledge Space Theory and Mathematics Theory as guidelines, and the characteristics of the knowledge and the way of expressing knowledge are analyzed here, and also the knowledge and its states and its relations are described by hypertext. Then they are adopted to establish the domain knowledge space and the span knowledge space and proximate knowledge space. Before testing and assessing, I divide information technology course standard of high school into five levels, and construct a structure model of knowledge space which is based on the standard of the curricula. It is used to make a standard structure in test and assessment. During the test and assessment, I give an example in basic knowledge of information technology and make to measure examination question of having an examination for student. The knowledge space of a student establishes by the first test and evaluating tests and more tests and evaluations. After the test and assessment, the corresponding knowledge space can be showed in effect by hypertext. According as the above dissertation and attestation, I design a whole model of the system and make a process to test and assess the knowledge space. Regarding this, 1 make a basic database in Microsoft Access and write some code in HTML. Finally, I show the knowledge space of the information technology by a tree mode in a web page.Besides, the knowledge and skill of students should be tested and assessed, and the same as course and method and emotion and attitude. So that it can provide teachers with references and helps to teaching , and provide students with guides and suggestions to study and development for the future. Let students study during test and study for developments.
