本文提出了一种新的天文学自我效能感工具,由两个因素组成;一个涉及学习天文学内容,我们称之为天文学个人自我效能感,另一个涉及使用天文仪器,特别是使用远程机器人望远镜进行数据收集。后者被称为天文学工具自我效能因素。该工具已被测试的可靠性和结构效度。信度检验表明,因子1的Cronbach's0.901,因子2的Cronbach' s0.937。通过计算单向方差分析建立结构效度,适当保护值,使用与结构外围相关的自变量。这些分析表明,这两个量表具有较高的结构效度。天文学的具体工具的发展是一个重要的步骤,在评估自我效能感作为一个先驱,调查在天文学领域的科学身份的建设。
This paper presents a new astronomy self-efficacy instrument, composed of two factors; one relating to learning astronomy content, which we call astronomy personal self-efficacy, and the other relating to the use of astronomical instrumentation, specifically the use of remote robotic telescopes for data collection. The latter is referred to as the astronomy instrumental self-efficacy factor. The instrument has been tested for reliability and construct validity. Reliability testing showed that factor 1 had a Cronbach’sof 0.901 and factor 2 had a Cronbach’sof 0.937. Construct validity was established by computing one-way analyses of variances, with thevalue suitably protected, using independent variables peripherally related to the constructs. These analyses demonstrate that both scales possess high construct validity. The development of this astronomy specific instrument is an important step in evaluating self-efficacy as a precursor to investigating the construct of science identity in the field of astronomy.
