Learning to “argue, question and communicate more like real scientists” may help students understand scientific concepts more deeply, researchers believe.
Both the Common Core State Standards for reading and mathematics and the Next Generation Science Standards have increased the focus within their disciplines on skills such as constructing and evaluating arguments, complex communications, disciplinary discourse, and critical thinking, said James W. Pellegrino, a co-director of the Learning Sciences Research Institute at the University of Illinois-Chicago.
“Although some think of these as general cognitive competencies, it turns out that reasoning and argumentation have to be disciplinary-based,” Mr. Pellegrino said. “Reason and argumentation in literature is not the same as it is in history, is not the same as it is in science.”
Florida State University’s laboratory school and local Gainesville-area secondary schools are testing a new method to teach reason and argumentation, reports Education Week. In “argument-driven inquiry,” small groups of 8th graders choose how to investigate a problem, run experiments, analyze data and “develop arguments to present to the rest of the class.”
Based on those discussions, the students may collect more data, reflect on their findings, and write up an “investigation report” that has to go through a double-blind peer review process, modeled on the peer review boards that professional journals use to screen scientific papers submitted for publication. Each student then revises his or her work and submits a final report.
In a pilot comparison study of 265 8th grade students in 16 classes at both the laboratory school and regular district-run schools, researchers at the university’s Center for Educational Research in Mathematics, Engineering, and Science found students using the traditional lab model engaged in more structured lab tasks than those in the argument-driven labs, but the latter labs went deeper during each task.
. . . After a year, the students in both lab models significantly improved their knowledge of scientific concepts, but only the students in the argument-driven inquiry labs had improved in science writing and in their understanding of the nature and development of science knowledge. Moreover, the students who were taught in the pilot labs showed nearly twice as much improvement in their ability to use and generate scientific explanations and arguments as the students in the traditional labs.
Another study looked at traditional science labs. Researchers found that “middle and early high school students often avoid setting a hypothesis that could be rejected, try to design and conduct experiments that would confirm biases they already hold, and reject evidence from an experiment that contradicts what they thought going into it.” Even when 8th graders entered a “scientifically accurate” interpretation of data, many “privately—and incorrectly—interpreted the results to confirm their initial hypotheses.”
