In this paper, we present a design solution that involves the bringing together of Project-based Learning (PBL) with the theory of usable knowledge (Pellegrino & Hilton, Developing transferable knowledge and skills in the 21st century, 2012). Usable knowledge is the ability to use ideas to solve problems and explain phenomena, an approach to science learning put forth by the Framework for K-12 Science Education (National Research Council (NRC), A framework for K–12 science education: Practices, crosscutting concepts, and core ideas, 2012) to optimize science learning environments. We offer a process for designing a curricular system that enhances how students learn science as a progression toward sophisticated practice of usable knowledge by focusing on coherence, depth, and motivation. We saw the potential of these distinct approaches for informing one another, and we extrapolate on 4 years of research that involves the process of iterating on our curricular design to best integrate the two approaches to support student learning.

The National Research Council’s Framework for K-12 Science Education and the Next Generation Science Standards (NGSS Lead States in Next Generation Science Standards: For states, by states. The National Academies Press, Washington, 2013) move teaching away from covering many isolated facts to a focus on a smaller number of disciplinary core ideas (DCIs) and crosscutting concepts that can be used to explain phenomena and solve problems by engaging in science and engineering practices. The NGSS present standards as knowledge-in-use by expressing them as performance expectations (PEs) that integrate all three dimensions from the Framework for K-12 Science Education. This integration of core ideas, practices, and crosscutting concepts is referred to as three-dimensional learning (NRC in Division of Behavioral and Social Sciences and Education. The National Academies Press, Washington, 2014). PEs state what students can be assessed on at the end of grade level for K-5 and at the end of grade band for 6–8 and 9–12. PEs do not specify how instruction should be developed nor do they serve as objectives for individual lessons. To support students in developing proficiency in the PEs, the elements of the DCIs will need to be blended with various practices and crosscutting concepts. In this paper, we examine how to design instruction to support students in meeting a cluster or “bundle” of PEs and how to blend the three dimensions to develop lesson level PEs that can be used for guiding instruction. We provide a ten-step process and an example of that process that teachers and curriculum designers can use to design lessons that meet the intent of the Next Generation of Science Standards.

We present teacher–researcher partnership (TRP) as a way of fostering teachers’ professional learning. Teachers’ participation as research group members is an essential aspect of the partnership. Teachers and researchers share the same goal, which is to improve their understanding of and enhance students’ engagement in science. Project-based learning (PBL) was selected as a means of enhancing student engagement. The activities of the partnership focused on the co-design and enactment of and co-reflection on PBL units. Teachers participated in the design of the data collection process and the interpretation of initial findings. As an indicator of teachers’ professional learning, we examined students’ engagement during different implementations of the PBL units. Student engagement was measured using a situational experience sampling questionnaire delivered via mobile phones. The students’ experiences of scientific practices and engagement in actual learning situations were measured in the first and second years of the teachers’ implementation of the teaching units. An analysis of the students’ responses showed that the students were 20% more engaged in the second year than in the first year. We argue that TRP has the potential to enhance teachers’ professional learning.
