Reading for evidence takes place in Twig Science Oklahoma via authentic, grade-appropriate science texts. By authentic texts, we mean reading materials in forms that students might encounter in the real world, for information and entertainment. By providing students with authentic texts, Twig Science Oklahoma encourages students to develop strategies that they can apply to their […]

Within Twig Science Oklahoma, with a focus on developing 21st century skills in the context of phenomena-based investigations, science and engineering understanding and language competence develop interdependently. The language demands of the Oklahoma Academic Standards are rigorous, and the pragmatic applications in the classroom require attention to both subject content and language. The Science and […]

Discover the Twig Science Oklahoma Assessment System Twig Science Oklahoma has created a three-dimensional assessment system to match the OASS. Twig Science Oklahoma supports teachers to deliver the three-dimensional learning required by the OASS, providing a three-dimensional assessment system that allows teachers to evaluate student attainment of OASS Performance Expectations. The assessment strategies measure students’ […]

Grade Progressions To make it easy for teachers to track student progress, each module contains a Scope and Sequence, which provides an overview of each chapter, and details the 3 Dimensions and Performance Expectations that are covered in each module and lesson. In addition, the Performance Expectation Progressions overview lays out what students are expected […]

Experiments Have Traditionally Been Over-Emphasized  Historically, for many educators, the indicator of a “good” science program was the number of experiments involved. These hands-on experiments would follow the scientific method: posing a question, testing a hypothesis, and drawing a conclusion. So it came as quite a shock when the National Research Council, in its “Framework […]

In each module, the Table of Contents summarizes student learning for every Driving Question, so teachers can see at a glance the student journey across a full module and the phenomena that will drive student inquiry. The PEs that students are working toward are also listed, and the different types of student investigation (hands-on, digital, […]

Investigations Based in Real-World Phenomena The three-dimensions of the OASS are united by the use of anchor phenomena, which provide opportunities for real-world application of DCIs, SEPs, and CCCs. Anchor phenomena present situations in which students can develop mastery of the three dimensions in contexts and stories that reflect their real-world experiences. There is an […]

The Foundations of 3–D Learning The OASS is built around three-dimensional learning—and so is Twig Science Oklahoma. The three dimensions that make up each OASS Performance Expectation—Disciplinary Core Ideas (DCIs), Science and Engineering Practices (SEPs), and Crosscutting Concepts (CCCs)—are at the very foundation of the Twig Science program. Each module clearly identifies where it addresses […]

We’ve created a 40-second video that outlines the Grade–Module–Driving Question–Lesson structure at the heart of Twig Science Oklahoma. Once you’ve got the hang of how it works, you’ll never look back, because every single Twig Science Oklahoma module adheres to the same logical and consistent design principles. Read our Program Instructional Design for a thorough […]

Collaborative ThinkTank Meet the team or, as we like to call ourselves, the Twig Science Collaborative Think Tank. The development of Twig Science Oklahoma has been guided by our collective commitment to making science accessible to all. We do this through our engaging, phenomena-based storylines and flexible range of captivating resources. We’d like to thank […]
