Abstract

ABSTRACT Experimental studies are often employed to test the effectiveness of teaching innovations such as new pedagogy, curriculum, or learning resources. This article offers guidance on good practice in developing research designs, and in drawing conclusions from published reports. Random control trials potentially support the use of statistical inference, but face a number of potential threats to validity. Research in educational contexts often employs quasi-experiments or natural experiments rather than true experiments, and these types of designs raise additional questions about the equivalence between experimental and control groups and the potential influence of confounding variables. Where it is impractical for experimental studies to employ samples that fully reflect diverse populations, generalisation is limited. Series of small-scale replication studies may be useful here, especially if these are conceptualised as being akin to multiple case studies, and complemented by qualitative studies. Control conditions for experimental studies need to be carefully selected to provide the most appropriate test for a particular intervention, and considering the interests of all participants. Control groups in studies that replicate innovations that have been widely shown to be effective in other settings should experience teaching conditions that reflect good practice and meet expected teaching standards in the research context.

教学创新的实验研究:应对方法论和伦理挑战
实验研究通常用于测试教学创新的有效性,如新的教学法、课程或学习资源。本文为开发研究设计以及从已发表的报告中得出结论的良好实践提供了指导。随机对照试验可能支持使用统计推断,但其有效性面临许多潜在威胁。教育背景下的研究通常采用准实验或自然实验,而不是真正的实验,这些类型的设计提出了关于实验组和对照组之间的等效性以及混杂变量的潜在影响的额外问题。在实验研究无法充分反映不同人群的样本的情况下,推广是有限的。一系列小规模的复制研究在这里可能很有用,特别是如果这些研究被概念化为类似于多个案例研究,并辅以定性研究。实验研究的对照条件需要仔细选择,为特定干预提供最合适的测试,并考虑到所有参与者的利益。在复制已被广泛证明在其他环境中有效的创新的研究中,对照组应体验反映良好实践并符合研究背景下预期教学标准的教学条件。

期刊介绍: The central aim of Studies in Science Education is to publish review articles of the highest quality which provide analytical syntheses of research into key topics and issues in science education. In addressing this aim, the Editor and Editorial Advisory Board, are guided by a commitment to: maintaining and developing the highest standards of scholarship associated with the journal; publishing articles from as wide a range of authors as possible, in relation both to professional background and country of origin; publishing articles which serve both to consolidate and reflect upon existing fields of study and to promote new areas for research activity. Studies in Science Education will be of interest to all those involved in science education including: science education researchers, doctoral and masters students; science teachers at elementary, high school and university levels; science education policy makers; science education curriculum developers and text book writers. Articles featured in Studies in Science Education have been made available either following invitation from the Editor or through potential contributors offering pieces. Given the substantial nature of the review articles, the Editor is willing to give informal feedback on the suitability of proposals though all contributions, whether invited or not, are subject to full peer review. A limited number of books of special interest and concern to those involved in science education are normally reviewed in each volume.
