摘要

文章历史:2013年12月6日接收修订形式2013年11月25日接受12月24日2013年10月8日在线发布本研究旨在确定土耳其托卡特中部省小学教育中在职科学教师在其课程中对科学过程技能(SPS)的知识、意识和使用程度。本研究采用一般描述性设计。本研究的目标人群是积极从事小学二级教学的教师,总体规模为87人,样本规模为62人,采用方便抽样的方法从目标人群中选择科学技术教师。在本研究中,“科学过程技能知识与意识量表”(SPS-KAS)和“科学过程技能使用程度量表”(DUSPS)都是由我们开发的,并被用作数据收集工具。在对24名四年级教师候选人(来自托卡特GaziosmanpasaUniversity)和21名在职科技教师(来自托卡特中部省份以外)进行了效度计算后,对量表进行了试点应用。为了进行效度评估,进行了项目区分计算,并使用那些具有0.3或以上“rjx”值的项目。在面孔效度和内容效度方面,采用专家意见。为了计算内部一致性信度量表,我们使用了KR-20公式,得到的结果为0,80。DUSPS量表的问题是使用五点李克特项目提出的,结构效度的结果意味着一个单一的因素。DUSPS的Cronbach alpha内部一致性系数为0.97。本研究结果表明,托卡特市仅有1.5%的在职科技教师对SPS有足够的了解,但他们都不能将SPS相关问题与具体的SPS联系起来。除此之外,11%的科学和技术教师承认在教学过程中尝试使用这些SPS。此外,教师的知识和意识根据他们的就职年份(新项目之前或之后)而有所不同。©2014 iojes。版权所有
