Research On The Application Of Portfolio Assessment Method In Senior One Biology Teaching

Now the basic education curriculum reform is in full swing in the country,As an important part of education curriculum reform,evaluation reform plays an important role in the success of reform.For biology,the new curriculum reform requires the subject enhance the students' biological science literacy for all students.Theory is with practice,truly implementing the "people-oriented" education.Then based on this kind of education concept,teaching evaluation is no longer limited to just rely on the scores,but to understand the students' comprehensive learning status to discover the advantages and disadvantages that students exist in the learning process to help students to correct them in time.It is also helpful for teachers to find out their problems in teaching so as to timely adjust teaching and improve teaching methods,to improve teaching efficiency.Therefore,under the education concept of new curriculum reform,grades in the past as the only evaluation standard for students' age can no longer be satisfied with the current education goal,it is famous for its evaluation process file reflecting its unique superiority.Portfolio assessment,also known as the growth record bag evaluation,the different scholars have different names for it.It can record the students' learning and growing process,and can show the students' achievements and works biological experiment in the process,which really reflects the students' subjectivity.Due to the biological experimental file cover itself is a dynamic process,it not only can reflect the students' learning status and efforts,but also help the students to make a simple plan for later study to improve the students' consciousness of landscape.At the same time,it can also make the teacher have a process of self-reflection,combining the reflective teaching with practice,using theory knowledge to guide practice,to improve the quality of biological experiment teaching and to promote the teachers' professional development.Therefore,this paper discusses how to use portfolio assessment in high school biology experiment teaching from both theory and practice.A questionnaire survey of high school biology teachers in the city of Kaifeng and the author's internship school,and the author's internship class high one(1)class,(2)class of all students Questionnaire surveys,in which the high one(1)class was the experimental class and the high one(2)class was the control class by conducting the research program of evaluation of the implementation.Through the observation,experiment and other methods,the two parallel classes had been studied for one semester.Through the analysis of questionnaires for teachers and students,finally,the author proposes the contents that should be collected in the high school biology experiment portfolio,Portfolio cover the main content of the collection including biological experiment operation evaluation,biological evaluation,biological experiment evaluation reflection in the process of the experimental and the satisfactory works he thinks.Students biological experiment evaluation index table was designed on the basis of the "ordinary high school biology curriculum standard" and the three dimensional goal by the author.The three aspects including biological experiments,biological experiment cooperation,biological experiment reflection are designed the specific ways and provided practical teaching cases by basing on experiment learning evaluation index table of evaluation.By comparison with the biological experiment,finally,we can find that it can not only improve the students' experimental grades and understand the overall design of experiments by the implementation of the biological experiment file cover,which also has great role in promoting for the entire biology.Finally,we found that the implementation of the biological experiment file cover not only can improve the students' experimental grades and understanding the overall design of experiments by comparison with biology.For the whole biology,it also has a great promoting effect.It can not only promote the harmonious relationship between teachers and students,but improve students' enthusiasm to study biological experiment.Meanwhile,it also can promote students' personal development and the improvement of teachers' professional accomplishment.For the overall effect,it not only make students in biological experiment knowledge and skills,attitudes,and emotions improve,also improve the enthusiasm of the students of the biological sciences to make performance have obvious improvement by the biological experiment file cover evaluation implementing.These contents the author hopes to survey can be used for reference by education workers.It provides some references for education workers to study the implementation of portfolio evaluation in teaching.
