Virtual Courseware: Web-Based Simulations for Promoting Inquiry-Based Teaching and Learning

Posted: Tuesday, January 3rd, 2012

by Paul Narguizian and Robert Desharnais

There is wide acceptance that inquiry-based curriculum programs have positive effects on cognitive achievement, process skills, and attitudes towards science. Science instructors seek engaging, effective, and inquiry-based activities that are convenient to implement in their classrooms. While the web provides a vast resource of declarative information (some of it multimedia), there are few places on the web where instructors can obtain effective inquiry-based tools for teaching science. The Virtual Courseware Project fulfills this need with interactive, web-based simulation activities that emphasize the methods of science for both life and earth science topics.

With Virtual Courseware, students learn by doing: making observations, proposing hypotheses, designing experiments, collecting and analyzing data generated by the software, and synthesizing and communicating results. The activities include an online assessment quiz that consists of randomized interactive questions. The students’ answers are graded automatically and stored in a database server, and a printable certificate of completion is issued for each student. The instructor can access student and class results, allowing them to quickly gauge how well the key concepts were understood. The simulations are designed to enhance traditional curricula and provide a supplement to experimental laboratory and field work.

As an example, the Drosophila activity allows students to simulate laboratory experiments where they breed fruit flies carrying visible mutations and analyze the offspring to determine the laws governing genetic inheritance. The paradigm for this activity is a “virtual lab bench” where students can order fly stocks carrying mutations, mate flies in an incubator, and view and count flies under a microscope. Experimental data are entered into a “lab bench computer” which is used for analysis. Data tables and images can be exported into a “laboratory notebook” and results from the notebook can be imported to create an on-line scientific report. This activity promotes inquiry-based learning and the scientific method because it allows students to propose hypotheses, design their own experiments, and collect and analyze data to test these hypotheses in an engaging virtual environment that mimics a laboratory setting.

Virtual Courseware Offerings

The development of Virtual Courseware began in 1995 with the release of the genetics application Virtual FlyLab. With the support of a series of NSF awards, several additional applications were developed in the areas of biology and earth science. These have been organized into four application suites:

  • Virtual Courseware for Inquiry-Based Science Education consists of Drosophila, described above, and two other applications to be released soon: Natural Selection, which allows students investigate the evolution of traits by performing laboratory experiments involving water fleas, and Relative Dating, where students can pose and test hypotheses regarding the order of the geological events represented in a geological cross section.
  • Virtual Courseware for Earth and Environmental Sciences includes two groups of activities. (1) Earthquake consists of a java-based simulation on determining the travel times of seismic waves and a second simulation on locating the epicenter and Richter magnitude of an earthquake. Also available is a version called Terremoto that is completely in Spanish. (2) Global Warming consists of two simulations and several interactive tutorials. Energy Balance allows students to explore the factors that determine the temperature on the Earth’s surface, and Future Climate Change allows students to experimentally manipulate simulations of Earth’s climate. Seven tutorials accompany these activities: Albedo, Carbon Cycle, Greenhouse Gases, Greenhouse Effects, Hydological Cycle, Milankovitch Cycles, and Seasons on Earth.
  • Geology Labs On-Line has five interactive tutorials: (1) Virtual Earthquake for earthquake epicenter and magnitude determination, (2) Virtual Dating—Isochron for determining the ages of rock and minerals, (3) Virtual Dating—Radiocarbon for determining the ages of fossils and archeological artifacts, (4) Virtual River—Discharge for determining the flow and other properties of rivers, and (5) Virtual River—Flooding for determining the frequency of flooding.
  • Biology Labs On-Line is a collection of 12 web-based simulations for biology education: CardioLab, DemographyLab, EnzymeLab, EvolutionLab, FlyLab, HemoglobinLab, LeafLab, MitochondriaLab, PedigreeLab, PopEcoLab, PopGenLab, and TranslationLab. It is a commercial web site hosted by the academic publisher Benjamin Cummings and jointly owned by the CSU Center for Distributed Learning and the publisher. A site-license for any of the simulations costs $133 per year.

Pre/In-service Teacher Training for Noyce Scholars

The Chancellor’s Office of the California State University was awarded a grant from the NSF NSDL program titled “Building Locally, Linking Globally: Networking Micro-Communities of Noyce Scholars for Advancing Innovations and Improvement in Mathematics and Science Education.” The Virtual Courseware Project partnered with the Noyce-NSDL team to train Noyce Scholars in the use of Virtual Courseware. Several in-person and on-line workshops were held and training materials were developed which became part of the Noyce Teaching Commons. Workshops were presented at annual western regional meetings of the Noyce Scholars and the Virtual Courseware Project hosted a one day series of hands-on workshops for over 60 Noyce Scholars in the Southwest.

The partnership has been a win-win-win situation for everyone involved. The Noyce-NSDL leadership team added another high quality instructional tool into its portfolio of on-line resources. The Virtual Courseware Project disseminated its materials to science majors who are committed to teach in high need schools throughout the nation. Most importantly, in these times of tight budgets and burgeoning technology, Noyce Scholars have been introduced to free and effective on-line simulations which allow them to implement inquiry-based learning in their classrooms in a fun and tech-savvy way.

This is the second in a series of articles that highlight features of the Noyce-NSDL project.

The Virtual Courseware Project was funded by several grants from the National Science Foundation: DUE 94552428, DUE 9752603, DUE 9980719, ESI 0352529, and DUE 0735011.

2016 – Already a Busy Year in California Science Education

Posted: Tuesday, February 9th, 2016

by Lisa Hegdahl

As I write this message, it is the waning days of January. Only the first month of 2016 and yet a great deal is happening in Science education within the California Science Teachers Association and the state of California as a whole. Indeed, this an exciting time to be a science educator. Let’s take a look back at all that has taken place these past few weeks.

California Science Framework Public Review Sessions

Science educators gathered in San Diego on December 2, 2015 to review and provide feedback on the first public draft of the California Science Curriculum Framework.

Science educators gathered in San Diego on December 2, 2015 to review and provide feedback on the first public draft of the California Science Curriculum Framework.

The beginning of January 2016 found California at the end of the first public review of the draft California Science Framework.  A dedicated, 25 member, CSTA NGSS Committee under the leadership of co-chairs Laura Henriques, Past President of CSTA, and Peter A’Hearn, CSTA Region 4 Director, coordinated 30 Framework review sessions in 22 California counties in which 625 educators participated. In addition, many people sent their feedback directly to the California Department of Education. The members of the NGSS committee, those that read the Framework, and those who attended and hosted review sessions, volunteered in order to make the Framework useful for all of us. This represents countless hours of personal time. You can be confident that CSTA will keep you informed about the dates for the 2nd public review of the draft CA Science Framework currently scheduled for June-July 2016. A copy of CSTA’s response to the first draft is available here (1MB). I will be attending the two meetings where public comments are considered (February 19 and March 18) by the Science Subject Matter Committee of the Instructional Quality Commission to advocate on behalf of CSTA membership.

The NGSS Crosscutting Concepts ARE Science Content!

Posted: Monday, February 8th, 2016

by Pete A’Hearn

“How come if people evolved from monkeys, monkeys aren’t turning into people now?”

Evolution-Ahearn-1

I’m going to bet that any science teacher who has taught evolution has run into this question at some point. There are a bunch of incorrect assumptions behind the question, including the idea that evolution is a process that we could observe occurring during our lifetimes. This idea is directly addressed as part of the NGSS Crosscutting Concept of Scale, Proportion, and Quantity with the idea that:

  • Phenomena that can be observed at one scale may not be observable at another scale.

and

  • Time, space, and energy phenomena can be observed at various scales using models to study systems that are too large or too small.

(Note that this is not the crosscutting concept called out in the middle school evolution topic. Teachers will need to used multiple crosscutting concepts as well as multiple practices in building coherent units – not just the ones highlighted in the standards). Learn More…

The Big Idea Page: A Creative Way to Emphasize the Crosscutting Concepts for Three Dimensional Learning

Posted: Monday, February 8th, 2016

by Jennifer Weibert

Making three-dimensional learning a reality in the classroom of teachers starting to implement the NGSS can be a struggle. In many cases, the Crosscutting Concepts are often an afterthought. According to A Framework for K-12 Science Education, “…the purpose of the Crosscutting Concepts is to help students deepen their understanding of the disciplinary core ideas, and develop a coherent and scientifically based view of the world” (NRC, 2012). This is achieved via the Crosscutting Concepts, “because they provide an organizational schema for interrelating knowledge from various science fields into a coherent and scientifically based view of the world” (Achieve, 2016). The NGSS were designed for all three dimensions (Science and Engineering Practices, Disciplinary Core Ideas, and Crosscutting Concepts) to work together allowing the teacher to create an environment where students make sense of real world phenomena. To measure the success of this in an NGSS aligned classroom, teachers need access to evidence of student understanding and thinking. The Big Idea Page was my solution for that. Learn More…
