Student science proficiency development demands sustainable and coherent learning environment support. Scholars argue that project‐based learning (PBL) is an efficient approach to promoting student science learning, compared to conventional instructions. Yet, few studies have delved into the learning process to explore how a coherent PBL system consisting of curriculum, instruction, assessment, and professional learning promotes student learning. To address the gap, this study investigated whether students' science proficiency on the three post‐unit assessments predicted their achievement on a third‐party‐designed end‐of‐year summative science test in a coherent high school chemistry PBL system aligned with the recent US science standards. The study employed a cluster randomized experimental design to test an intervention using our PBL system and only used data from the treatment group. The sample consisted of 1344 treatment students who participated in our PBL intervention and underwent the pretest and end‐of‐year summative test. Students' responses to the three post‐unit assessments were selected and rated to indicate their science proficiency. Two‐level hierarchical linear models were employed to explore the effects of students' performances of three post‐unit assessments on their end‐of‐year summative achievement, considering and controlling for student prior knowledge (i.e., pretest and prior post‐unit assessments). This study suggests two main findings. First, students' science proficiency in the three units could cumulatively and individually predict their summative science achievement. Second, students' performances on the two types of tasks (i.e., developing and using models) in the three post‐unit assessments could also be used to predict their summative science achievement. This research contributes to the field by showing that a coherent standards‐aligned PBL system can significantly and sustainably impact student science proficiency development.
Transforming standards into classrooms for knowledge-in-use: an effective and coherent project-based learning system
Global science education reform calls for developing student knowledge-in-use that applies the integrated knowledge of core ideas and scientific practices to make sense of phenomena or solve problems. Knowledge-in-use development requires a long-term, standards-aligned, coherent learning system, including curriculum and instruction, assessment, and professional learning. This paper addresses the challenge of transforming standards into classrooms for knowledge-in-use and presents an iterative design process for developing a coherent and standards-aligned learning system. Using a project-based learning approach, we present a theory-driven, empirically validated learning system aligned with the U.S. science standards, consisting of four consecutive curriculum and instruction materials, assessments, and professional learning to support students’ knowledge-in-use in high school chemistry. We also present the iterative development and testing process with empirical evidence to support the effectiveness of our learning system in a five-year NSF-funded research project. This paper discusses the theoretical perspectives of developing an NGSS-aligned, coherent, and effective learning system and recaps the development and testing process by unpacking all essential components in our learning system. We conclude that our theory-driven and empirically validated learning system would inform high school teachers and researchers across countries in transforming their local science standards into curriculum materials to support students’ knowledge-in-use development.

Abstract -
null (Ed.)Engaging students in science learning that integrates disciplinary knowledge and practices such as computational thinking (CT) is a challenge that may represent unfamiliar territory for many teachers. CompHydro Baltimore is a collaborative partnership aimed at enacting Next Generation Science Standards (NGSS)–aligned instruction to support students in developing knowledge and practice reflective of the goals laid out in A Framework for K–12 Science Education (National Research Council 2012) “... that by the end of 12th grade, all students possess sufficient knowledge of science and engineering to engage in public discussion on related issues … and are careful consumers of scientific and technological information related to their everyday lives.” This article presents the results of a partnership that generated a new high school level curriculum and teacher professional development program that tackled the challenge of integrating hydrologic learning with computational thinking as applied to a real-world issue of flooding. CompHydro Baltimore produced Baltimore Floods, a six-lesson high school unit that builds students’ water literacy by engaging them in computational thinking (CT) and modeling practices as they learn about water system processes involved in urban flooding (See Computational Thinking and Associated Science Practices). CompHydro demonstrates that broad partnerships can address these challenges, bringing together the diverse expertise necessary to develop innovative CT-infused science curriculum materials and the teacher supports needed for successful implementation.more » « less

We describe a professional development model that supports teachers to integrate computational thinking (CT) and computer science principles into middle school science and STEM classes. The model includes the collaborative design (co-design) (Voogt et al., 2015) of storylines or curricular units aligned with the Next Generation Science Standards (NGSS Lead States, 2013) that utilize programmable sensors such as those contained on the micro:bit. Teachers spend several workshops co-designing CT-integrated storylines and preparing to implement them with their own students. As part of this process, teachers develop or modify curricular materials to ensure a focus on coherent, student driven instruction through the investigation of scientific phenomena that are relevant to the students and utilize sensor technology. Teachers implement the storylines and meet to collaboratively reflect on their instructional practices as well as their students’ learning. Throughout this cyclical, multi-year process, teachers develop expertise in CT-integrated science instruction as they plan for and use instructional practices that align with three dimension science teaching and foreground computational thinking. Throughout the professional learning process, teachers alternate between wearing their “student hats” and their “teacher hats”, in order to maintain both a student and teacher perspective as they co-design and reflect on their implementation of CT-integrated units. This paper illustrates two teachers’ experiences of the professional development process over a two-year period, including their learning, planning, implementation, and reflection on two co-designed units.more » « less

This article describes a professional development (PD) model, the CT-Integration Cycle, that supports teachers in learning to integrate computational thinking (CT) and computer science principles into their middle school science and STEM instruction. The PD model outlined here includes collaborative design (codesign; Voogt et al., 2015) of curricular units aligned with the Next Generation Science Standards (NGSS) that use programmable sensors. Specifically, teachers can develop or modify curricular materials to ensure a focus on coherent, student-driven instruction through the investigation of scientific phenomena that are relevant to students and integrate CT and sensor technology. Teachers can implement these storylines and collaboratively reflect on their instructional practices and student learning. Throughout this process, teachers may develop expertise in CT-integrated science instruction as they plan and use instructional practices aligned with the NGSS and foreground CT. This paper describes an examination of a group of five middle school teachers’ experiences during one iteration of the CT-Integration Cycle, including their learning, planning, implementation, and reflection on a unit they codesigned. Throughout their participation in the PD, the teachers expanded their capacity to engage deeply with CT practices and thoughtfully facilitated a CT-integrated unit with their students.more » « less
