Current science education policy posits that scientific practices of inquiry are the all-time context for student science learning. McConney and colleagues analyzed information from the Programme for International Student Assessment (PISA), an international assessment of high school science students, to test the relationship between inquiry-based teaching and student outcomes in (a) science literacy, (b) interest in scientific discipline, and (c) engagement in science. Their assay showed that while students in high-inquiry classrooms reported higher than boilerplate interest and engagement in scientific discipline, they had lower than boilerplate scientific literacy scores. The contrary was as well truthful: students with lower levels of scientific inquiry pedagogy scored higher than average on science literacy measure and lower on measures of interest and engagement.

The newspaper provides a succinct and comprehensive overview of different approaches to inquiry-based education, ranging from confirmation to structured, guided, and open up. The authors cite the literature demonstrating positive correlations between inquiry-based pedagogy and science literacy, noting that the strongest positive effects have oftentimes been associated with guided research, with highest effects when inquiry was structured and so that students were engaged in examining and evaluating the quality of evidence and then developing explanations for phenomena. They define confirmation inquiry as investigations that reinforce previously introduced ideas. In structured inquiry, students are required to generate explanations. Guided inquiry has students developing their ain research methods to accost a enquiry question posed past the teacher. Open inquiry is designed to accept students replicate practices of scientists in which they develop their own questions, design and behave out investigations and communicate their results. The authors also cite contempo studies that accept produced contrary results, where student scientific performance was negatively correlated with student-centered pedagogy.

In their analysis of PISA information, the researchers use a definition of inquiry that correlates most closely with open enquiry: "practices in which students may be responsible for naming the scientific questions under investigation, designing investigations to research their questions and interpreting findings."

Research Design

The researchers investigated the following questions using PISA data from xv-year-quondam students in Australia, Canada, and New Zealand:

  • To what extent do students report high levels of inquiry-oriented learning activities in their science classes?
  • What levels of scientific discipline literacy, involvement in science, and date in science correlate with students who report high levels of classroom inquiry versus those who report low levels?

New Zealand, Canada, and Australia were called for the analysis considering, the authors land, they accept consistently performed well on the PISA and are similar in their sociocultural histories and traditions. The data gear up included 1,252 schools and 41,685 students across the three countries.

Vi PISA items related to the frequency of instructional strategies were identified as collectively representing bear witness of whether students had experienced high or low research-based instruction. These indicators included how frequently students were required to: (1) explicate ideas, (two) blueprint how a scientific discipline question could be investigated in a laboratory, (3) choose an investigation topic, (four) design their own experiment, (5) carry an investigation to exam out their ain ideas, and (6) draw conclusions. The researchers used responses to these half-dozen items to form a low-enquiry group and high-research group for each country. In all three countries, the low-inquiry and high-inquiry groups were almost the same size. The authors notation that they could not assess the quality of these instructional strategies, simply their beingness.

For student engagement in science, researchers used six PISA variables including general science interest, enjoyment of science, personal and general valuing of science, self-efficacy in science, and science self-concept. Science literacy and interest in science were represented by students' scores on the PISA science items.

Enquiry Findings

In all three countries, students who reported having experienced loftier levels of inquiry-oriented instruction scored, on average, below their country's boilerplate on the PISA test of scientific literacy. However, they had above-average levels of interest in science and of appointment in science. The contrary was also truthful: students who had experienced low levels of inquiry-oriented didactics had college-than-average scientific literacy scores, but lower than average interest and engagement in scientific discipline.

Implications for Practice

The results of this study non only run counter to common understandings of the power of inquiry-based instruction inside the breezy science education (ISE) field, simply as well challenge current science education policies including the recommendations of PISA itself, which advocates for inquiry-based instruction. Rather than suggesting that we disbelieve or uncritically embrace the written report results, the authors of the paper suggest a need for closer consideration of why such unexpected results were obtained. They posit two possibilities: The first is that teachers are non adequately supported to provide high quality research-based instruction in ways that would produce improved scientific discipline literacy. If this is correct, the written report suggests a need for further focus on teacher development. But it nevertheless begs the question as to why previous meta-studies did not produce the same result. A second possible reason, they suggest, could be that the PISA questions are not well aligned (not sensitive) to positive effects of inquiry-based instruction. The study thus is valuable at least every bit much for the questions it provokes as information technology is for the findings it describes. Questions may be one of the more productive ways in which research and practice can relate, with each exploring, in different ways, possible answers to these questions.

This paper is extremely interesting for practitioners. In improver to the to a higher place implications for practice, information technology provides a good review of the literature of inquiry-based science studies, as well as a good reminder to ISE practitioners almost the ongoing need to attend to the quality of enquiry-based education.

McConney and colleagues' enquiry also sheds lite on the complexity of the relationship research and practice. Inquiry-based knowledge is not produced past ane written report, but by an accumulating body of evidence that, over the long run and in different settings, produces consensus, if tentative, understandings.
