Purpose: This project will develop and test Happy Atoms, a physical modeling set and an interactive iPad app for use in high school chemistry classrooms. Happy Atoms is designed to facilitate student learning of atomic modeling, a difficult topic for chemistry high school students to master. Standard instructional practice in this area typically includes teachers using slides, static ball and stick models, or computer-simulation software to present diagrams on a whiteboard. However, these methods do not adequately depict atomic interactions effectively, thus obscuring complex knowledge and understanding of their formulas and characteristics.
Project Activities: During Phase I (completed in 2014), the team developed a prototype of a physical modeling set including a computerized ball and stick molecular models representing the first 17 elements on the periodic table and an iPad app that identifies and generates information about atoms. A pilot study at the end of Phase I tested the prototype with 187 high school students in 12 chemistry classes. Researchers found that the prototype functioned as intended. Results showed that 88% of students enjoyed using the prototype, and that 79% indicated that it helped learning. In Phase II, the team will develop additional models and will strengthen functionality for effective integration into instructional practice. After development is complete, a larger pilot study will assess the usability and feasibility, fidelity of implementation, and promise of Happy Atoms to improve learning. The study will include 30 grade 11 chemistry classrooms, with half randomly assigned to use Happy Atoms and half who will continue with business as usual procedures. Analyses will compare pre-and-post scores of student's chemistry learning, including atomic modeling.
Product: Happy Atoms will include a set of physical models paired with an iPad app to cover high school chemistry topics in atomic modeling. The modeling set will include individual plastic balls representing the elements of the periodic table. Students will use an iPad app to take a picture of models they create. Using computer-generated algorithms, the app will then identify the model and generate information about its physical and chemical properties and uses. The app will also inform students if a model that is created does not exist. Happy Atoms will replace or supplement lesson plans to enhance chemistry teaching. The app will include teacher resources suggesting how to incorporate games and activities to reinforce lesson plans and learning.
The mixed methods randomized experimental study assessed a model of engagement and education that examined the contribution of SciGirls multimedia to fifth grade girls’ experience of citizen science. The treatment group (n = 49) experienced 2 hours of SciGirls videos and games at home followed by a 2.5 hour FrogWatch USA citizen science session. The control group (n = 49) experienced the citizen science session without prior exposure to SciGirls. Data from post surveys and interviews revealed that treatment girls, compared to control girls, demonstrated significantly greater interest in their
STEM Pathways is a collaboration between five Minnesota informal STEM (science, technology, engineering, and mathematics) education organizations—The Bakken Museum, Bell Museum of Natural History, Minnesota Zoo, STARBASE Minnesota, and The Works Museum—working with Minneapolis Public Schools (MPS) and advised by the Minnesota Department of Education. STEM Pathways (logo shown in Figure 1) aims to provide a deliberate and connected series of meaningful in-school and out-of-school STEM learning experiences to strengthen outcomes for students, build the foundation for a local ecosystem of STEM
Living Liquid is a full-scale development project that will develop and research a new genre of science exhibit that engage visitors in inquiry with large scientific datasets through interactive visualizations. Building on findings from a prior pathways project, Living Liquid will develop three interactive visualizations on a multi-touch Viz Table with a tangible user interface. Each visualization will support visitors in the exploration of a dataset provided by the project’s science partners: 1) Plankton Patterns will show how the ocean is defined by regions of microscopic life using data from the MIT Darwin Project; 2) Ocean Tracks will reveal the “highways” large marine creatures travel with data from the TOPP project at Stanford University; and 3) Genetic Rhythms will follow the activity of marine creatures’ genes in response to environmental conditions based on data from the Center for Microbial Oceanography Research and Education (C-MORE). Through an iterative process of collaborative research and development among museum professionals, educational researchers, computer scientists, marine biologists, data artists and interaction designers, this project seeks to: (1) Advance public understanding of ocean ecosystems and large data inquiry skills through the development of a Viz Table. (2) Advance STEM professionals’ knowledge of how to engage the public in inquiry with visualizations through an educational research study. (3) Increase the capacity of STEM professionals (both ISE developers and research scientists) to develop visualizations through a collaborative development process that includes graduate student training and residencies.
