Research On SOLO Classification Of Ability Structure Of Biology Exam Papers In Recent Three Years

College entrance examination as a selection test that transport talents to colleges and attract much attention in its content and form.In the context of the new curriculum reform,along with the deepening reform of the examination admissions system,the entrance exam papers pay more attention to the examination of students' abilities and overall quality.High school biology as a natural science that occupy a pivotal position in the college entrance examination,so it is quite important to study the ability structure of the biology exam papers in recent three years.By the guidance of SOLO classification theory,this paper taking the2015-2017 New Curriculum ? Volume,New Curriculum ? Volume,and Beijing Science Volume as the research sample,based on the implicit thinking of the examination papers,according to the level of thinking needed to answer the questions correctly,to divide the concrete ability structure of exam questions in biology entrance examination into four levels: single point structure level(M),multi-point structure level(M),associated structure level(R)and expanding abstract structure level(E).From the test type and knowledge module,the specific competency structure of each test paper is divided,and further study by horizontal and vertical directions on above test papers which gradually obtained the ability structure and SOLO level distribution trend of biological test papers with different years and different paper types.The results show : The trend of SOLO level in 2015-2017bio-examination basically showed single peak characteristics,and most of the peak appeared in R level,M-level second only.In all levels of SOLO theory,U-level questions play a role in reducing difficulty in the test paper,the proportion of questions basically fluctuates between 15% and 20%;M-level questions have the function of examining students' comprehensive knowledge,Each level of the papers are up and down in the 30%;R-level questions is themain level of college entrance examination that can distinguish middle and upper students,the number of questions should be controlled at about45%;E-level test questions have the function of examining students' innovative thinking,inductive deduction and other high-level thinking,and can select top-notch talents with comprehensive ability.The proportion should not be too high which can be controlled below 10%.Secondly,the multiple-choice questions focus on the M and R levels but non-choice questions are mainly on the R levels on the types of questions which indicating that the entrance examination questions pay more and more attention to students' innovative ability,transfer ability and reasoning ability and the new curriculum proposed three-dimensional goals and training of students as the center of teaching philosophy is move forward through the guidance of college entrance examination;In the specific knowledge module,the test questions pay more attention to examine the accumulation of the "molecular and cellular" module students' accumulated knowledge of details in recent years,to avoid speculation when students review psychology and emphasize the solid foundation of knowledge.At the same time,it focuses on creating new problem situations based on the scientific frontier progress of the "steady state and environment" module,examines students' comprehensiveness of thinking problems and reflects high-level thinking.And based on this conclusion,it puts forward some meaningful suggestions for biology teaching,college entrance examination propositions and scientific preparation.
