Eliciting Student Thinking

Science Scope—January/February 2024

 

Discover student thinking while analyzing data…and having fun! (Data Literacy 101)

Science Scope—January/February 2024

Our students rarely practice data skills with data not related to our science content, which makes sense given all we must teach. But always asking our students to succeed at the data skill move (e.g., graphing, analyzing, interpreting) and the content move (connecting it to what they are learning) at the same time can be a lot of pressure. Cognitively, this is a lot for novices and thus makes it trickier to elicit students’ ideas around the data and the content.

Making Scientific Sensemaking Visible

Science Scope—January/February 2024

Many teachers and schools are coming to recognize the importance of sensemaking in the science classroom. But what does an NGSS-informed sensemaking lesson look like in practice, and how might our students respond to this shift in our instruction? This article explores a sample lesson cycle involving sensemaking with an 8th-grade science classroom around a physics topic. The two-week lesson highlights the four elements of sensemaking: phenomena, science and engineering practices (SEPs), student ideas, and science ideas. Samples of student work and audio recordings of their discussions suggest that students engaged in critical thinking and collaboration as part of the sensemaking process as they researched to construct explanations and designed solutions around a local community problem. By centering students as agents for change, this lesson demonstrated how all students can create a multitude of viable solutions to real-world problems.

Exploring Socioscientific Issues through Evidence-Based Argumentation with MEL Diagrams

Science Scope—January/February 2024

Critical thinking skills are best taught as students participate in the scientific practice of argumentation. When engaged in scientific argumentation students are expected to engage in active listening and social collaboration through the process of negotiation and consensus building. Socioscientific issues are ideally suited for such activities. Model-Evidence-Link (MEL) diagrams provide an ideal scaffold for helping students learn to build arguments that can help them make connections between evidence and scientific explanations. In these activities students compare competing models by making plausibility judgements, then comparing how well scientific evidence supports each model. In research-based activities these scaffolds have been shown to help students better understand scientific concepts, shift their plausibility judgements, and provided insights into how students negotiation consensus through argumentation. In this article we share both the resources and instructional methods for including MEL diagrams in the middle school classroom.

The Science Practice of Modeling as a Sensemaking Tool

Science Scope—January/February 2024

By , ,

Does the scientific practice of modeling actually support students in making thinking visible? Middle school teachers can build from the work of 12 K–8 teachers who wanted to learn how the practice of modeling is developed across grades and analyze how those skills end up looking in middle school. They gave their students the same phenomenon and prompts, tried them out with their students, collected models to compare them, and then came together across two years to discuss modeling. All students across the grades showed similarities in the models, both in terms of how they presented ideas and the scientific ideas. Many middle school models looked similar to those in early grades, and although middle school students showed particles of air in the models, the usefulness of the particles to explain the phenomenon was almost always unclear from the models alone. Implications for assessment of middle school students include discussing models with students to assess their knowledge and including fewer student scaffolds at the onset.

Promoting Sensemaking Through an Impactful Instructional Sequence

Science Scope—January/February 2024

By ,

A valuable framework for promoting sensemaking includes the convergence of two independent ideas: (1) the focus of modern education on teaching for understanding and transfer, and (2) a purposeful sequence of instruction with those ends in mind. In essence, the sensemaking framework intends to help educators identify the big ideas we want students to understand at a deep level (e.g., construct evidence-based claims from firsthand experiences) to transfer their learning to new situations. This conception is perfectly aligned with the NGSS emphasis on teaching science through the conceptual lenses of Core Ideas (called Disciplinary Core Ideas [DCIs], Practices (Called Science and Engineering Practices [SEPs]) and Crosscutting Concepts (CCs) rather than fixating on factual information only. In addition, this view aligns with the four NSTA's critical attributes that including phenomena, science and engineering practices, student ideas, and science ideas (see https://www.nsta.org/sensemaking). The explore-before-explain instruction sequence helps teachers prioritize students constructing evidence-based claims in the sensemaking framework. What follows is a description of the four key planning considerations for sensemaking and how explore-before-explain teaching plays out in practice for teaching middle school students about thermal energy transfer.

Making light work of gravity: Scaffolding middle schoolers’ thinking to help them understand gravitational lensing.

Science Scope—January/February 2024

By , , ,

Although the NGSS has helped teachers conceptualize teaching science in a more integrated way, effectively scaffolding students’ thinking within and across lessons can still be a challenge for any middle school science teacher. Thinking about the curriculum structure can be useful for scaffolding across lessons (Figure 1). While many curriculum structures exist (Posner, 2003), some structures are better at providing the teacher opportunities to promote sensemaking across lessons and units. For example, a spiral curriculum is where relevant prior concepts are revisited in order to connect them to new concepts. Revisiting concepts is meant to deepen students’ knowledge rather than merely repeating previous content (Harden, 1999). In our state, each middle grade has NGSS standards for life, physical, and earth/space science. We’ve found the spiral curriculum was useful to help students see connections across science disciplines. Our light unit (Table 1) comes before our unit on space science (Authors, 2018). In this article, we demonstrate how we scaffold students’ learning to help students make connections between lessons about light (MS-PS4-2) and gravity (partially addressing MS-ESS1-2). We use these experiences to help students understand gravitational lensing
