| This research base on the idea of improving of middle school bio-science accomplishment in standard course of biology (experiment draft),guided by multivariant intelligence theory, to study how to put multivariant teaching tactics experiment into practice in high school bio-teaching.This study based on the teaching material and the current level of students, through puting multivariant teaching tactics experiment into practice, to realize the teaching effect and the problem remaining to be solved in teaching and to find the effective method to improv the quality learning bio-science conscientiously.This artical is discussed from the several aspects following:Preface: Introduce the study background, study significance and the current research situation.Section one: The theory study of science accomplishment and bio-science accomplishment: Discuss the connotation of science accomplishment and bio-science, and construct the valuation index of bio-science accomplishment.Section two: The basic theory of bio-experiment teaching: the basic theory of middle school bio-experiment teaching is able to build a platform for contracting and realizing multivariant teaching tactics.Section three: The study of the relationship between the high school bio-experiment and the science accomplishment: to make bioexperiment and bio-science accomplishment relation clear in different point of view, in order to improve bio-science accomplishment in teaching tactics.Section four: The study of multivariant teaching tactics for improving bio-science accomplishment: multivariant intelligence theory is coincident with the idea of reformation of new course for improving bio-science accomplishment; multivariant intelligence is not only the aim but also the content of teaching, and also the measure and tactics of teaching.Section five: Practice and case revelation of multivariant teaching tactics for improving bio-science accomplishment: this part is the main body of the article, mainly discuss the practice in the experimental teaching of the high school bio-teaching tactics, including the process and measure of the study, test and the inquiring result, the analysis and discuss of result and the correlative conclusion is also included.The object of this research is the four class of sophomore in our school, divide the students into comparison group and experimental group, we teach the experimental group with multivariant teaching tactics and the comparison group in the routine way; the knowledge, ability, method , emotion attitude of student is studied, the former and test result is made T-test, self-partner test and one way ANOVA (taking level of significance is 0.05), so that to estimate the effect of multivariant teaching tactics for promoting high school student's bio-science accomplishment. The analysis result shows no significant different in knowledge,the emotion attitude level between the two groups (partner probability of T-test is 0.268, 0.575, respectively); The experimental group obviously precede the comparison group in T-test designs analysis, experiment method and apply scientificly (partner probability of T-test is 0.001, 0.002, 0.031, respectively), difference is come from mainly in teaching method. major students have interest in this teaching tactics very much, think that it is helpful to develop their discipline thought, and their bio-science accomplishment has had very big rise (for example analysis, the ability of experiment design, and understanding and mastery to science process and method).Section six: This section mainly put forward proposals for multivariant teaching tactics in teaching target ascertaining, the content of courses choosing, and teaching process combined with the teaching practice. The author think that teaching target ascertaining, the content of courses choosing, and teaching process are the main factors affecting the effect and target-reaching of teaching.We should ascertain the target according to the course criteria and the actual level of student in teaching, and put teaching into practice according to concrete content;We should create circumstances and atmosphere in practicing, to encourage active thought of student, accomplish studying, help students to structure new knowledge, promote their ability, and improve bio-science accomplishment gradually.Certainly, the promoting effect of multivariant teaching tactics in experiment operation, thought and solving the actual problem etc, for high school pupils is to be studied further now the day after tomorrow.
