The impact of epistemic framing of teaching videos and summative assessments on students' learning of scientific methods.

The incorporation of epistemic aspects of science in science education continues to be a challenge for researchers and practitioners. The paper presents an empirical study investigating how epistemic framing of scientific methods can be incorporated in science teaching, learning and summative assessment, and what impact such framing has on student learning outcomes. The study was conducted with 969 secondary students taught by 152 teachers from a national sample in England. Teaching videos and summative assessments were framed by Brandon's Matrix, a theoretical framework derived from the work of a philosopher of science and focusing on the diversity of scientific methods ranging from hypothesis testing to non-manipulative parameter measurement. The findings are discussed, including (a) the students' views on the teaching videos and summative assessments, (b) the impact of the teaching videos on students' understanding of the epistemic aspects of scientific methods and (c) students' performance on summative assessments in the context of science topics covered in high-stakes examinations in England. The findings suggest that the students' understanding of scientific methods significantly improved after watching the videos. Furthermore, the students' performance on the summative assessment items indicated a high level of accuracy in responses.

General Certificate of Secondary Education (GCSE) and the assessment of science practical work: an historical review of assessment policy.

This article responds to two key concerns in science education: firstly, that policies designed to assess practical work have distorted its use as an effective pedagogical tool. Secondly, it addresses concerns about the lack of research on the assessment of practical work. The article analyses the policy trajectory for the assessment of science practical work, through the GCSE, in the English National Curriculum from 1988 to the present day. Drawing on published research and policy documents, using Bowe, Ball and Gould's policy cycle approach to policy analysis, we first identify three distinct eras which represent different ways of assessing practical work from 1988 to the present day. Second, we demonstrate that the interaction between high-stakes assessment narrows the ways practical work is conducted in schools. The interaction between curriculum policy and assessment policy and its influences on pedagogy for practical work has been influenced by the high-stakes nature of the tests. This is not a unique case to England nor to science education. Finally, we question whether we can design assessments, 'tests worth teaching to', that can withstand the implications of high-stakes testing.
