Abstract:
Objective: This study aims to develop the Special Education Instructional
Adjustment Scale of Ordinary School Teachers, and test validity and reliability of scale.
Methods: Through the analysis of the literature, experts reviewed and established the
pre-test items of the scale, and used item analysis, factor analysis, reliability analysis
to examine 150 ordinary school teachers with a pre-test. Result: Item analysis shows:
t value of each item has 3.0 or higher (p < 0.001), shows that each item is appropriate
and reliable; When three items are removed, factor analysis shows, the load of
each factor are between 0.500~ 0.830, total variance explain 74.653%; reliability
analysis shows, the Cronbach alpha coefficients of the “environmental adjustment”,
“curriculum adjustment”, “teaching adjustment” and “assessment adjustment” are 0.903,
0.904,0.928,0.908,the Cronbach alpha of the whole scale is 0.963; Conclusion: This
scale has satisfactory validity, reliability, and can try to use in related research fields in
the future.
目的:本研究旨在制订普通学校教师的特教教学调整量表,并检验有
关量表的效度与信度。方法:利用文献分析、专家检阅编制量表的预试题目,
并以项目分析、因素分析、信度分析来对150名普通学校教师进行了预试。结果:
项目分析显示,每一个题目 t 值在 3.0 以上(p < 0.001),显示每个题目是适切、
可靠;当删除了3个题目后,其因素分析显示,各题目因素负荷量在 0.500~0.830
之间,解释总变异量为 74.653%;信度分析显示,量表的“环境调整”“课程调
整”“教学调整”“评量调整”四个层面的 Cronbach α 系数分别是 0.903、0.904、
0.928、0.908,整个量表 Cronbach α 系数为 0.963。结论:有关量表具有良好的
信效度,可尝试在未来相关研究领域使用。
