| In 2013, "the opinions about pushing forward the reform of middle and primary school education quality evaluation" was issued by the ministry of education, establishing the quality of primary and middle school students academic evaluation system of green. The test is one of the important means of evaluation, it is also the main way to carry out large-scale education evaluation. Open questions has the advantages on checking the flexibility and universality of the students’ thought, checking the students’practical ability and innovation consciousness, and checking emotion, attitude, values and so on and that cannot be replaced by closed questions. The score of open questions has great impact on the effectiveness and reliability of the overall score. Based on the score in the practice of open physics questions in junior middle school, to compare the scoring method of "Double-digit Coding" that currently used in large-scale academic assessment project and the scoring method of "SOLO" that introduced in the domestic more than ten years, expecting to provide reference on how to make physical open questions scoring more scientific, to promote evaluation combined with physics teaching.In order to achieve the purpose of research, this study determines the research content as follows:The applicability of SOLO classification theory on the scoring of physical open questions.A comparative study on the scoring methods of "Double-digit Coding" and "SOLO" in physics open questions. Including:process evaluation concept, the establishment of the scoring criteria, criteria framework level of comparative analysis, scale efficiency, feasibility and operability, reliability, two between raters score results for evaluation of students’physical quality is effective, etc.The role of the structure of two kinds of evaluation method of in the analysis of students’cognition for the knowledge and to guide physics teaching.In the preparation stage of this study, I selected four physical open questions from the evaluation project that Science Education Institute of Guangxi Normal University as research tools, then test the eighth or ninth grade students in the class, and asked the classes’physical teachers make evaluation according to students’grades. The author based on the research of the SOLO classification theory make the SOLO grading standards for each topic, and asked the experts’ review and modify. In order to compare grading efficiency of two scoring methods, the reliability between raters of two scoring methods, etc, train two raters for every subject and ask them use two scoring methods grading papers respectively, and interview the raters. Finally arrange interview results, and use the SPSS20.0 software to deal with the corresponding data and correlation analysis.In order to further analysis of the two scoring methods, this study also interviewed several teachers who have minimum 5 years working experience in physics teaching, to understand their views on physical open question score.Affter the above study, the results were shown as follow:(1) the scoring methods of SOLO is applicable in the explore type open questions of physics. Physics open questions include some operational or other types, if SOLO is applicable needs further research.(2) In the comparative study, the scoring method of "Double-digit Coding" and the scoring method of "SOLO" are practical, that is to say the two methods of grading ratings on physics open questions is feasible and operational.(3) Most of the graders feel SOLO score is more efficiency than double coding score.(4) By the level of the two criteria framework contrast, the low level of is corresponding to SOLO is corresponding to the low level of "Double-digit Coding", the high level of SOLO is corresponding to the high level of "Double-digit Coding" thus, to some extent, there is some internal consistency between SOLO level of classification and "Double-digit Coding".(5) Found that use of these two kinds of evaluation methods, the reliability between graders is high, at the same time, they can evaluate students’physical quality of learning effectively.(6) The two scoring methods have their own advantages and disadvantages, but to some extent, they can guide physics teaching.The innovation of this article is that study the two scoring methods is based on the practice, the scoring methods are used in the grading physics open questions in junior middle school to compare. |
