Investigation and Design Can Improve Student Learning in Science and Engineering; Changes to Instructional Approaches Will Require Significant Effort

WASHINGTON – Centering science instruction around investigation and design can improve learning in middle and high schools and help students make sense of phenomena in the world around them.  Current approaches to science in many classrooms do not reflect this approach and constrain the opportunities afforded to students, says a new report from the National Academies of Sciences, Engineering, and Medicine. Changing instructional approaches will require significant and sustained work by teachers, administrators, and policy makers, the report says.

“Students learn by doing, and science investigations provide an opportunity to do,” says Brett Moulding, co-chair of the committee that wrote the report and director of the Partnership for Effective Science Teaching and Learning. “Our report provides guidance on how teaching can shift toward investigations in a way that piques students’ curiosity and leads to greater interest in science.”

The term “investigation” refers to all aspects of engaging in science and engineering practices, whether in the laboratory or outside of it.  In classrooms using these approaches, students ask questions, participate in discussions, create artifacts and models to show their reasoning, and continuously reflect and revise their thinking. Teachers guide, frame, and facilitate the learning environment to allow student engagement and learning. Thus, instead of discussing “laboratories” as one component of science classes, the report explains how to make “investigation” the central focus of what students do to learn science and engineering.

Science investigation and engineering design offer a promising vehicle for anchoring student learning in contexts that are meaningful to them, the report says. Interacting with real-world phenomena allows instructional choices that better connect to students’ lives, experiences, and cultural backgrounds than science instruction that is focused on discrete facts organized by discipline.

While recent years have seen advances in the understanding of how students learn science and engineering concepts, the experiences of students in middle and high school classrooms have remained relatively unchanged. Whereas traditional science classroom activities promote knowledge of vocabulary, facts, and concepts, science investigation and engineering design promotes learning that simultaneously engages with science and engineering practices, disciplinary core ideas, and crosscutting concepts that have broad scientific applications. This approach was introduced in the Framework for K-12 Science Education (National Research Council, 2012) and helps students make sense of the natural and engineered world. Incorporating this approach into middle and high school classrooms is a dramatic change from the status quo and will entail significant changes for both students and teachers.

Given the potential for science investigation and engineering design to motivate students’ learning, the report recommends that teachers arrange their instruction around interesting phenomena or design projects and use their students’ curiosity to engage them in learning. The report also says that instructional resources and curricula designed to support science investigation and engineering design should use approaches consistent with knowledge about how students learn, and also include information on strategies and options teachers can use to craft and implement lessons relevant to their students’ backgrounds and cultures.

“When investigation and design are at the center of learning, students can gather evidence and take ownership of the evidence they have gathered,” said Nancy Songer, co-chair of the committee that wrote the report and professor in the School of Education at Drexel University.

As student learning goals are changing, so must professional learning for teachers, the report says.  High quality, sustained professional learning opportunities are needed to engage teachers with effective evidence-based instructional practices and models for instruction in science and engineering.

Professional development leaders should provide teachers with the opportunity to learn in the manner in which they are expected to teach, and empower teachers to make informed decisions about adapting lessons to their students, says the report. School and district administrators should also identify and encourage participation in sustained professional learning opportunities that enable teachers to develop successful approaches to science and engineering teaching and learning.

The report also recognizes the need for science and engineering to be more inclusive and to ensure that students from groups that have been excluded or marginalized in the past have equitable access to quality science and engineering learning opportunities.

School and district staff should review policies that impact the ability to offer science investigation and engineering design opportunities to all students, the report says. This effort should include particular attention to differential student outcomes, especially in areas in which inequities have been well documented, such as gender, socioeconomic status, race, and culture. Administrators should use this information to construct specific, concrete, and positive plans to address the disparities.

Engaging all students in investigation and design can only happen if the complex factors outside the classroom support their work, the report says. Influences come from policies and practices at the school, district, regional, state, and national levels. States, regions, and districts should provide resources to support the implementation of investigation and engineering design-based approaches to instruction across all grades and in all schools, and should track and manage progress towards full implementation. State, regional, and district leaders should also ensure that the staff in their own offices who oversee science instruction or science educators are knowledgeable about these approaches to teaching and learning. Conscious alignment of goals and intentionality in addressing equality, equity, and inclusion by the various stakeholders can facilitate improvements in curriculum, instruction, assessment, and professional development needed to support science investigation and engineering design for all students.
