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 gene (LCT) is a 55 kilo-base pair 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.

Welcome to our three Google Summer of Code students

Google Summer of Code 2013Three international students will spend the summer coding for our open source projects. Through Google Summer of Code (GSoC), they’ll earn stipends from Google, plus get a coveted GSoC t-shirt and certificate.

Expansion of SPARKS HTML5 circuit simulator

Our HTML5 breadboard simulator allows students to experiment with basic DC and AC circuits using linear components (resistors, capacitors, inductors) and to perform measurements with a function generator, a digital multimeter and an oscilloscope.

Sabareesh Nikhil C, from Hyderabad, India, will extend our existing circuit-solving code to handle non-linear components such as diodes, op amps and transistors. Instead of treating each circuit as a lumped impedance and computing its response to a single frequency, the new code will perform a more realistic time-based computation, which will enable it to model the behavior of more complex circuits. Sabareesh also plans to implement a communication protocol that will enable circuits on different computers to communicate with each other.

Sabareesh will work with Concord Consortium mentors Paul Horwitz, Sam Fentress and Richard Klancer.

Probe your browser!

Science classrooms use probes and sensors to enable real-time data collection by students. Currently we use Java applets to support communication between sensors and web-based applications in the browser. Increasingly limited support for Java is making it difficult to integrate probes and sensors that use Java software for use in the classroom.

Lingliang Zhang from New York, NY, and Abu Dhabi, United Arab Emirates, will design a native application for desktops, which will make the data from probes and sensor hardware available to our browser-based JavaScript applications. The native application will use an embedded webserver to connect to our existing sensor library. This approach will enable browsers on desktops and laptops to use our currently supported Pasco and Vernier sensor devices without a Java applet.

He will work under the mentorship of our Senior Software Engineer Scott Cytacki.

Port HTML5 interactives to phones and tablets

Our HTML5 interactives are rendered using a semantic layout system. With a modified UI, they could work on phones, allowing students to interact with them on multiple devices. Additionally, with an iOS and Android application created using Cordova, users could install the interactives and use them offline. This app could also allow parts of the engine behind the interactives to run natively in order to get better performance on these devices.

Apoorv Narang from New Delhi, India, will measure performance on various devices to determine which of our HTML5 interactives can be run on these devices. He will improve our lab framework, which is the system that displays and runs interactives, with the goal of making our interactives look—and run!—better on phones.

Director of Technology Stephen Bannasch will mentor Apoorv.

During summer 2012, we were fortunate to have two fabulous GSoC students, including Piotr Janik, who continues coding for us as a consultant. Watch Piotr describe his experience with Google Summer of Code.

We can’t wait to see the code that our three new GSoC students will develop this summer!

 

Share and embed—easily!

One of the key features of our Next-Generation Molecular Workbench is the ability to easily share and embed interactives in blog posts, learning management systems, emails and more—wherever you can paste a weblink or HTML code. Just two simple steps will have you sharing your favorite interactives with all your friends and colleagues in no time flat!

  1. Click the Share link at the top of an interactive.
  2. Copy and paste the link into Facebook, Google+, Twitter, Pinterest or wherever you want to share the interactive.

Want to embed the interactive in your own blog or web page instead?

  1. Click the Share link at the top of an interactive.
  2. Copy the HTML and paste the iframe code where you want the interactive to appear.

Video: Molecular Workbench Brings Science to Life in the Browser

As we make our award-winning Molecular Workbench software more accessible and widely available, we’re documenting our story at the same time. Google’s grant to the Concord Consortium funds the conversion of MW from Java to HTML5 so it will run in modern Web browsers. This will reduce barriers for using the next generation MW in schools. Students will be able to access the software from a Web page on a school computer, iPad, or smartphone, giving them anywhere, anytime access to powerful science learning opportunities.

We’re creating videos to share our conversion story. We’ll describe Molecular Workbench, our technical development process, and the benefits of HTML5. We’ve teamed up with the excellent staff of Good Life Productions to produce these videos.

In the first video, Concord Consortium’s Director of Technology Stephen Bannasch describes the power of the modern Web browser to bring science to life. Enjoy.
