Assessing Science

Assessment

In science, assessment should also emphasize practical application. Teachers can use portfolios or project-based assessments where students document their scientific investigations and reflect on their processes. These methods not only evaluate students’ understanding but also develop their ability to communicate scientific knowledge (NGSS Lead States, 2013).

Formative and Summative Assessments

Teachers can use a combination of formative assessments (e.g., quizzes, projects, or class discussions) and summative assessments (e.g., final exams or presentations) to evaluate students’ understanding of integrated science concepts. Formative assessments provide immediate feedback that can guide future instruction, while summative assessments evaluate long-term learning (Hattie & Timperley, 2007).

The California Science Test (CAST), is a statewide assessment designed to measure how well students understand the Next Generation Science Standards (NGSS). Administered in grades 5, 8, and once in high school, the CAST evaluates students’ ability to think like scientists and engineers by applying knowledge of physical, life, and Earth and space sciences. Instead of focusing on memorization, the test emphasizes real-world problem solving, data analysis, modeling, and explaining scientific phenomena using evidence. The CAST includes interactive items, such as simulations, data sets, and multi-step tasks, that give students opportunities to demonstrate deeper understanding. The results help educators and families monitor student progress and guide instruction to ensure all students gain strong scientific literacy and critical thinking skills.

Intervention

Preteaching Key Concepts

Pre-teaching key concepts before a science lesson helps students build background knowledge and prepares them to better understand new information during whole-group instruction. By introducing essential vocabulary, ideas, and processes ahead of time, teachers reduce cognitive overload and increase student confidence and participation. Pre-teaching is especially effective for English learners and students who need additional academic support because it allows them to engage more fully in hands-on investigations and discussions.

Interactive Simulations and Videos

Interactive simulations and videos enhance science instruction by allowing students to visualize and explore concepts that may be difficult to observe directly in a classroom. These tools support deeper understanding by providing dynamic models of scientific processes, encouraging inquiry, and allowing students to test ideas in a safe, controlled environment. Interactive media can increase engagement, support diverse learning styles, and help clarify abstract concepts through animations and guided exploration.

Guided Science Notebooks

Guided science notebooks are structured tools that help students organize their observations, questions, and reflections during science lessons. They provide prompts, diagrams, and sentence starters that guide learners through the scientific process, supporting note-taking, data recording, and conceptual understanding. By using guided notebooks, students can track their learning over time, make connections between experiments and concepts, and practice scientific writing and communication skills. These notebooks are especially beneficial for struggling learners and English learners, as they scaffold thinking and provide a clear framework for documenting ideas. Additionally, they give teachers valuable insight into students’ reasoning and progress, helping to inform instruction and intervention.

Language Support for English Language Learners in Science

Language support for English learners (ELs) in science and other content areas is essential for helping students access complex concepts while developing academic language skills. Strategies such as providing sentence starters, visual aids, and structured discussions give students scaffolds to express their thinking clearly and participate fully in lessons. For example, sentence starters like “I predict that…,” “The evidence shows…,” or “I notice that…” guide students in sharing observations, explanations, and reflections. Tools like RELIEA (Reading, English Language Instruction, and Engagement for Achievement) can further support comprehension by combining explicit language instruction with content learning, ensuring students build both vocabulary and conceptual understanding. By integrating these supports, teachers create an inclusive environment where multi-lingual students can confidently engage with science, communicate ideas, and strengthen their language development.
