We describe the development, design, implementation, and preliminary classroom results of an innovative curriculum, "Focus on Energy," that supports learning about energy in Grades 4-5. The curriculum is grounded in the concepts of science as practice, model-based reasoning, and learning progressions, and builds on students' pre-existing…

This study examines and compares how developers designed two primary science curricula to support teacher adaptation and enable use of innovative materials at scale. The two cases--"Literacy Science" (a science and literacy curriculum for grades 2-5) and "Science as Inquiry" (a curriculum focused on matter for grades 3-5)--were…

The integration of artificial intelligence (AI) topics into K-12 school curricula is a relatively new but crucial challenge faced by education systems worldwide. Attempts to address this challenge are hindered by a serious lack of curriculum materials and tools to aid teachers in teaching AI. This article introduces the theoretical foundations and…

This research examines factors influencing elementary science teacher learning as they participate in professional development with and enactment of educative curricula in comparison with learning following limited professional development and enactment of traditional curricula. Using a randomized cluster design (125 teachers and 2,694 students in…

Project-Based Learning (PBL) is a teaching method in which students learn by actively engaging in real-world, personally meaningful projects that allow conceptual transformation to occur within the educational process while fostering intellectual curiosity in a supportive learning environment. PBL supports students developing deep content…

Evolution by natural selection is key to understanding life and of considerable practical importance in public health, medicine, biotechnology, and agriculture. "The Next Generation Science Standards" (NGSS) include natural selection among several evolutionary concepts that all third-graders should know. This article explores a novel…

STEM (Science, Mathematics, Engineering and Technology) education has widely been considered to have the potential to prepare students with 21st-century skills. Though the Government of Bangladesh (GoB) is concerned with developing human resources for the 21st-century, STEM education has not yet achieved a strong position in the national…

Background and Context: We explored how learning trajectories (LTs) might be used to design variables instruction. Objective: We aimed to develop an LT for variables and use it to guide curriculum development for fourth graders working in Scratch in an integrated mathematics+CS curriculum. Method: We synthesized learning goals (LGs) and levels of…

Background: Early exposure to Computer Science (CS) and Computational Thinking (CT) for all is critical to broaden participation and promote equity in the field. But how does the introduction of CS and CT into primary school curricula impact learning, perception, and gaps between groups of students? Methodology: We investigate a CS-curricular…

One of the aims of science curriculum is to understand technology that is used in all areas of daily life. Thus, science curriculum should be revised in a feasible and dynamic manner for the quality. The purpose of the study is to investigate primary school teachers' opinions about renewed 3rd grade science curriculum. The sample of the study…

New reform documents underscore the importance of learning both the practices and content of science. This integration of practices and content requires sophisticated teaching that does not often happen in elementary classrooms. Educative curriculum materials--materials explicitly designed to support teacher and student learning--have been posited…

Early adolescents, particularly from underrepresented or marginalized communities, may feel disconnected from school science leading to a lack of engagement. The lack of connection between their out of school experiences and school science may lead them to devalue science. This study examines interviews with 56 middle school students and 12…

The Philippines implemented its educational reform commonly known as K to 12 Program in 2013 for Filipino learners' holistic development and global competitiveness. One indicator of the reform's effectiveness is the country's performance in international large-scale assessments like the Trends in International Mathematics and Science Study…

The purpose of this study was to investigate the alignment between the fourth-grade summative classroom assessments and the 'Matter and Energy' unit in the Lebanese science curriculum using: content and cognitive levels. Summative assessments were collected from a sample of 17 schools. The alignment between the classroom assessments and the…

More than half of U.S. children fail to meet proficiency standards in mathematics and science in fourth grade. Teacher professional development and curriculum improvement are two of the primary levers that school leaders and policymakers use to improve children's science, technology, engineering and mathematics (STEM) learning, yet until recently,…
