Recent reforms in science education have promoted students’ understanding of how science works, including the methodological approaches used by scientists. Given that teachers are expected to teach and promote methodological pluralism, it is worth examining how teachers understand and view scientific methods, particularly when scientific methods are presented as a diverse array and not as a linear model based exclusively on hypothesis testing.The empirical study presented in the paper examines science teachers’ understanding of scientific methods, particularly the diversity of scientific methods. Brandon’s Matrix, a philosopher’s account of scientific methods, has been adapted for educational purposes, and two tasks were developed in order to investigate teachers’ understanding of scientific methods. Fifty-six science teachers (25% male, 75% female) from different regions in the UK responded to an online survey.The results showed that the majority of the teachers showed satisfactory understanding of basic components of Brandon’s Matrix. However, more than half of the sample held naïve understanding of scientific methods. By providing insight into teachers’ misconceptions about scientific methods, the study provides suggestions for the design of teacher training programmes and highlights the need for explicit instruction about scientific methods. In addition, we suggest the use of heuristics such as Brandon’s Matrix for the development of pedagogical tools as well as research instruments.

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.

The rapid changes in science and society during the last decade have demonstrated the need for readiness to address the uncertain future through the development of future-oriented skills. Despite previous attempts, there is still no consensus regarding what is meant by “future-oriented skills” and how these could be integrated into science curricula. Stakeholders’ views about what future-oriented skills are and how they should be taught would provide a clearer understanding of their needs and their perceived characteristics of effective new teaching approaches. Thus, given the pivotal role that policymakers play in education policies, this study investigated the views of 35 policymakers based in the United Kingdom, Italy, Finland, and Lithuania. Participants completed an online survey that elicited their views on future-oriented skills, as well as ways of integrating them into national science curricula. The data analysis included descriptive statistics and qualitative analysis based on the principles of thematic analysis. The qualitative analysis followed a combination of inductive and deductive coding approaches. The findings of this study highlight that among other skills, participants stressed the need for introducing problem-solving and critical thinking in science classrooms in order to better address the uncertainty of future challenges, such as environmental issues. Therefore, policymakers seem to agree that there is a need for moving away from traditional teacher-centred approaches when teaching future-oriented skills. These results provide valuable insights into policymakers’ needs and expectations. In doing so, this study can serve as a starting point for a systematic approach toward integrating future-oriented skills into science curricula.

Background: The paper discusses how the design of summative assessments of practical science can be enhanced through the use of robust theoretical models that capture the diversity of scientific methods. The developments in assessment policy in England and the role of practical science in teaching and learning of science are reviewed. Purpose: The paper has two main purposes: (a) to explore how summative assessments of practical science can potentially reflect the breadth of scientific methods; and (b) to investigate how Year 10 students in England engage with and perceive summative assessments designed using Brandon's Matrix, a framework clarifying the diversity of scientific methods. Sample: The paper draws on data from Year 10 (14-15 years old) students with a sample of physics assessment tasks developed using Brandon's Matrix. Design and methods: The study focused on the development of a series of assessment questions based on Brandon's Matrix, a framework by a philosopher of science, who classifies scientific methods in a taxonomy. Students' performance on the assessments as well as their perceptions about practical science are investigated. Conclusion: The results suggest that students held a very narrow understanding of what a scientific method is and often linked it to hypothesis testing, variable manipulation and measurement of several variables. Furthermore, they reported not to enjoy drawing conclusions from data.

A significant issue in the teaching, learning and summative assessment of practical science is that the underpinning model of scientific methods is based on a fairly simplistic and linear account that does not represent how scientists actually do practical work. In this paper, we examine how science teachers in England and Wales view scientific methods included in teaching and summative assessment of practical science. Following on a survey of 51 secondary teachers’ views, we focus on the outcomes of a professional development programme where science teachers were introduced to a framework called Brandon’s Matrix that presents a diversity of scientific methods in the context of Project Calibrate. Through in-depth qualitative analysis, we investigated how three teachers engaged with this framework having taught it to their students. The findings illustrate that teachers conceptualise practical science as a mainly hands-on activity, while they express the need for the inclusion of more minds-on skills in the high-stakes assessment of practical science. In addition, the findings show that teachers are quite receptive to adapting new frameworks, such as Brandon’s Matrix, for their teaching. Although the teachers did not see a significant departure of the assessment questions from the regular high-stakes tests taken at age 16, they did recognise that there was a valuable element of thinking skills embedded in them.

Research indicates that teachers lack a sophisticated understanding of Nature of Science (NOS), which in turn, can impact their instructional decisions and students’ understanding of NOS. The aim of the study was to investigate United Arab Emirates (UAE) early years’ science teacher’s (N = 433) perceptions about the NOS. Results obtained from a 70-item questionnaire revealed that teachers have an adequate understanding on many aspects related to science and NOS, especially those pertaining to the ‘Social-Institutional’, ‘Scientific Practices’ and ‘Educational Applications’ categories. However, varied perceptions were found on some key concepts such as the role of bias and prejudices on scientific facts, the employment of same scientific practices across different branches of science, and the influence of politics in science. Misconceptions on particular aspects of NOS were also recognised (e.g. the distinction between laws and theories and the fixed nature of procedures followed in experiments). The findings suggest practical and pedagogical implications for teaching and outline an agenda for further research.
