Lights, camera, action: A video that introduces the NGSS practice of scientific argumentation

Following the recommendation to incorporate the Next Generation Science Standards (NGSS) science and engineering practices in their classrooms, schools across the country are looking for ways to integrate scientific argumentation into their curriculum. Since 2012 the High-Adventure Science project in collaboration with National Geographic Education has offered free online modules for Earth and space science topics—including climate change, freshwater availability, the future of energy sources, air quality, land management, and the search for life in the universe—that include multiple opportunities for students to engage in argument from evidence.

Over 67,000 teachers and students across the globe have used High-Adventure Science modules. Based on teacher feedback, classroom observations, and analysis of student data, we have learned that when students engage in argumentation from data and model-based evidence, they need a lot of support on how to write a convincing argument.

Last year, we added an introductory activity to each module where students learn about the component parts of a scientific argument before they are asked to write one. In this highly scaffolded task, students see written examples of a claim and explanation and learn about uncertainty in scientific data and how to express this uncertainty. In High-Adventure Science, argumentation takes a special form, including a multiple-choice structured claim, open-ended explanation, five-point Likert scale uncertainty rating, and uncertainty rationale.

In this introductory activity, students learn about the components of a good explanation.

Even with this new activity, some students still struggled, so we recently created an animated video to introduce the scientific practice of developing an argument. We start by helping students identify the difference between a scientific argument and so-called “arguments” they may have with their friends (e.g., arguing about favorite ice cream flavors!), and making the distinction between claims backed by evidence and opinion. The goal is to introduce students to scientific arguments in a fun and relatable way and to make the terminology and process of scientific argumentation less daunting.

We’re piloting the video in our Will there be enough fresh water? module for select students. We’re looking forward to student and teacher feedback and may revise the video based on their comments. We want everyone to be able to engage in the critical practice of arguing from evidence.

We welcome your comments about our video, as well as your challenges and successes with incorporating the NGSS practice of engaging in argument from evidence.

Exploring hurricane datasets in the classroom

In August 2017, Hurricane Harvey evolved from a series of thunderstorms to one of the first major hurricane landfalls in the United States since early 2005. Right on the heels of Harvey, Hurricane Irma blasted through the Caribbean and onto the U.S. mainland, striking Florida in early September.

The National Oceanic and Atmospheric Administration (NOAA), which aims to understand and predict changes in weather, provides educational resources and datasets about hurricanes.

The dataset for 2005-2015 is available in our Common Online Data Analysis Platform (CODAP), a free and open-source web-based data analysis tool, geared toward middle and high school students.

With all the current catastrophic news about hurricanes, students have lots of questions. Use the data to help them understand the history and characteristics of storms.

  • To investigate the paths that hurricanes generally follow, use the slider to change the year from 2005 to 2015, and watch the data points on the map, which represent the general path of the storms.
  • To determine the storm with the highest wind speed, click the top data point in the wind speed graph, which plots year against highest wind speed. Since data is linked across multiple representations, the data point is highlighted on the graph and in the table, so you can find the name and date of that particular storm (e.g., Wilma, October 15, 2005, with top wind speeds of 160 mph).
  • To learn which year had the most or least number of storms, look at the storms per year graph. Notice an outlier in the data with year 2005, which had 15 storms during that season. (Note: This was the same year as Hurricane Katrina. Select KATRINA in the table and make sure the slider is set to 2005, then see the path of the hurricane graphed on the map.)
  • To see a relationship between wind and pressure, click on the Graph button. Drag the Maximum Wind column header from the table to the vertical (y) axis until the axis turns yellow. Drag the Minimum Pressure to the horizontal (x) axis until the axis turns yellow. (Note: you may need to scroll to the far right of the Case Table to see these columns.) 

Analyzing and interpreting data is one of the key science and engineering practices of the Next Generation Science Standards (NGSS), and representing and interpreting data are featured throughout the Common Core State Standards (CCSS) for mathematics. Students can use publicly available datasets from storms and other weather events to learn more about the world around them.

Chinese translation of SageModeler systems dynamics modeling tool

In June, Professor Silvia Wen-Yu Lee and her team at the National Changhua University of Education in Central Taiwan offered a 10-hour modeling curriculum to approximately 100 seventh grade students. Students used a new Chinese language version of SageModeler to model the relationship between marine biology and human activity in a unit about environmental conservation.

SageModeler is a free, web-based systems dynamics modeling tool for middle and high school students to construct dynamic models. SageModeler is being developed by the Building Models project, a collaboration between the Concord Consortium and the CREATE for STEM Institute at Michigan State University (MSU).

Professor Lee met Joe Krajcik, one of the lead writers of the Next Generation Science Standards and Principal Investigator (PI) of the Building Models project at MSU, where she had served as a visiting professor in 2014. Dan Damelin is the project’s PI at the Concord Consortium. Thanks to this fortuitous collaboration, Lee and her team translated SageModeler into Chinese, and her students are now taking advantage of this easy-to-use tool to create dynamic systems models.

“The students learned how to draw models instantly after a brief demonstration,” Lee noted. “Our teachers were amazed by the students’ level of engagement and by the students’ attention to the relationships when they are working together on the SageModeler. ” Professor Lee and her colleagues at the National Changhua University of Education hope to understand how the students develop competencies in model building and whether they develop clear understandings of the causal and dynamic relationships in marine biology and human activity (fishing) through modeling.

You can build your own model in five easy steps.

  1. Open SageModeler (in English or Chinese)

  2. Add variables to the canvas
    First, brainstorm factors that affect marine biology. What contributes to it and what is affected by it? Now, add images for each variable to the canvas.

  3. Link variables and set relationships
    Draw links from one variable to another and select from a menu to set the relationships between those variables. By using words and pictures of graphs, students can define the underlying equations that will be used to run the model.

  4. Run the model
    Open the simulation controls and run the model to collect data. Adjust the model settings to see how changing the variables affects the outcome. Does the model output data make sense? Does it match real-world data? Are the relationships between variables set up appropriately?

  5. Revise and expand your model
    Revise your model to better match the phenomenon you are modeling. For example, you may want to add more variables. As you continue to ask new questions, you can revise your model and deepen your understanding of the system.

We are currently working on additional internationalization efforts, including Turkish and Spanish translations. Interested in learning more or contributing a translation? Contact us.

National Teacher Appreciation Day & Teaching System Modeling with SageModeler

We are delighted to highlight the work of Erin Cothran from Hudson (Massachusetts) High School, for National Teacher Appreciation Day! Erin is teaching a 10th grade chemistry unit she developed based on the driving question, “How can something that can’t be seen crush a 67,000 lb. oil tanker made of half-inch steel?” The unit includes four activities:

  • Why do my ears hurt when I dive in the deep end of the pool?
  • Why do I have to let air out of my car tires in the summer but add more air to my tires in the winter?
  • Why does a soda can explode if it is left unopened and in a hot car?
  • How can a big metal drum be crushed using air pressure?

Each activity includes opportunities for students to build, test, and revise systems models using our free, web-based SageModeler dynamic modeling software.

Erin said, “Using SageModeler has changed how I teach about systems modeling. With the the Next Generation Science Standards being adopted by many schools, modeling has become a main focus of lessons. Working with SageModeler over the past year has allowed me insight into how computer models can be used to help answer questions.”

“I am able to facilitate my students’ learning about the components that make good models effective,” she noted. “Even more importantly, students are discovering that models need to be adjusted as science evolves, that it is okay to not get it correct on the first attempt. Through learning how to build models they are able to define relationships between variables and test their ideas. They love picking custom images, making links, and running the simulation to see the outcomes.”

Dan Damelin, a Principal Investigator of our Building Models project, which is developing SageModeler, reports, “Erin is a very thoughtful teacher who engages students by using the models they generate to drive class discussion.”

The Building Models project is a collaboration between the Concord Consortium and the CREATE for STEM Institute at Michigan State University. The project is researching how the use of a semi-quantitative systems dynamics tool to construct external models helps students build mental models as well as how teachers and curriculum materials can support and scaffold student learning with respect to the interplay between external and internal models. We look forward to learning more from Erin and all the Building Models research teachers.

Evo-Ed Integrative Cases will be enriched to address NGSS

A new collaborative research project at the Concord Consortium and Michigan State University will develop and research learning materials on the molecular and cellular basis for genetics and the process of evolution by natural selection. These two areas are both difficult to teach and learn, and although they have been historically taught separately, they are interlinked and span multiple levels of organization. The goal of Connected Biology: Three-dimensional learning from molecules to populations is to design, develop, and examine the learning outcomes of a new connected curriculum unit for biology that embodies the conceptual framework of the Next Generation Science Standards.

Peter White, science education researcher and entomologist at Michigan State University (MSU); Louise Mead, Education Director at the BEACON Center for the Study of Evolution in Action at MSU; and postdoctoral fellow Alexa Warwick at the BEACON Center visited the Concord Consortium recently to plan our joint work together. Frieda Reichsman and Paul Horwitz will serve as the Principal Investigator and Co-PI at the Concord Consortium.

The new units will leverage the contextually rich Evo-Ed Integrative Cases, which build directly on the interlinked nature of evolution and genetics and connect the science ideas with meaningful real-world examples. The Evo-Ed case studies track the evolution of traits from their origination in DNA mutation, to the production of different proteins, to the fixation of alternate macroscopic phenotypes in reproductively isolated populations. For example, the Evolution of Lactase Persistence case study examines the genetics, cell biology, anthropology, and biogeography of this system.

The human lactase protein, above, is made from the lactase gene, a 55,000 basepair segment of the second chromosome.

The curriculum will integrate the three dimensions of science—the core ideas of biology, the science and engineering practices, and the crosscutting concepts—to support all students in building toward deep understandings of biological phenomena. The project will be guided by two main research questions:

  1. How does learning progress when students experience a set of coherent biology learning materials that employ the principles of three-dimensional learning?
  2. How do students’ abilities to transfer understanding about the relationships between molecules, cells, organisms, and evolution change over time and from one biological phenomenon to another?

Note: If you’ve used the Evo-Ed cases in your classroom, we’d love to get your feedback! Please respond to this short survey to be entered into a drawing to receive a $50 Amazon gift card.
