中学生科学假设质量评价量表的制定

在前人工作的基础上,本研究对中学生科学猜想与假设质量的评价进行了进一步探索。研究根据PTA量表法,确定预见度、支撑度和独创性为评价的三个基本要素,用特尔斐法确定了其权重分别为0.4、0.4、0.2并制定出三个基本要素的评价量表,最后整合形成中学生科学猜想与假设质量的评价量表。评价量表的初步应用表明该评价量表具有良好的评分者一致性,整体可操作性较强,可以在更大范围内用于中学生科学猜想与假设质量评定的探索。

Establishing a Scientific Hypothesis Quality Scale for Secondary School Students

This study focused on the further exploration of how to evaluate the quality of secondary school students' scientific hypotheses on the basis of previous work of other researchers.According to the Pri- mary Trait Analysis,predictability,sustainment and originality had been set as three key factors for the evaluation;according to the result of Delphi Method weights (0.4,0.4,0.2) were allotted to them re- spectively;eventually a Hypothesis Quality Scale was established.The implementation of the scale indi- cated that the Hypothesis Quality Scale had a good reliability and was easy to operate;therefore it could be applied in the secondary school students' hypothesis evaluation.
