The PhET Interactive Simulations group at the University of Colorado is expanding their expertise of physics simulations to the development of eight-to-ten simulations designed to enhance students' content learning in general chemistry courses. The simulations are being created to provide highly engaging learning environments which connect real life phenomena to the underlying science, provide dynamic interactivity and feedback, and scaffold inquiry by what is displayed and controlled. In a second strand of the project, a group of experienced faculty participants are developing and testing lecture materials, classroom activities, and homework, all coordinated with well-established, research-based teaching methods like clicker questions, peer instruction, and/or tutorial-style activities, to leverage learning gains in conjunction with the simulations. The third strand of the project focuses on research on classroom implementation, including measures of student learning and engagement, and research on simulation design. This strand is establishing how specific characteristics of chemistry sim design influence engagement and learning, how various models of instructional integration of the sims affect classroom environments as well as learning and engagement, and how sim design and classroom context factors impact faculty use of sims. To ensure success the project is basing sim design on educational research, utilizing high-level software professionals (to ensure technically sophisticated software, graphics, and interfaces) working hand-in-hand with chemistry education researchers, and is using the established PhET team to cycle through coding, testing, and refinement towards a goal of an effective and user friendly sim. The collection of simulations, classroom materials, and faculty support resources form a suite of free, web-based resources that anyone can use to improve teaching and learning in chemistry. The simulations are promoting deep conceptual understanding and increasing positive attitudes about science and technology which in turn is leading to improved education for students in introductory chemistry courses both in the United States and around the world.
The Physics and Chemistry Education Technology (PhET) Project is developing an extensive suite of online, highly-interactive simulations, with supporting materials and activities for improving both the teaching and learning of physics and chemistry. There are currently over 70 simulations and over 250 associated activities available for use from the PhET website (http://phet.colorado.edu). These web-based resources are impacting large number of students. Per year, there are currently over 4 million PhET simulations run online and thousands of full website downloads for offline use of the simulations. The goal is that this widespread use of PhET's research-based tools and resources will improve the education of students in physics and chemistry at colleges and high schools throughout the U.S. and around the world. This PhET project combines a unique set of features. First, the simulation designs and goals are based on educational research. Second, using a team of professional programmers, disciplinary experts, and education research specialists enables the development of simulations involving technically-sophisticated software, graphics, and interfaces that are highly effective. Third, the simulations embody the predictive visual models of expert scientists, allowing many interesting advanced concepts to become widely accessible and revealing their relevance to the real world. And finally, the project is actively involved in research to better understand how the design and use of simulations impacts their effectiveness - e.g. investigating questions such as "How can these new technologies promote student understanding of complex scientific phenomena?" and "What factors inhibit or enhance their use and effectiveness?".

This collaborative project between Tufts University and the Massachusetts Institute of Technology is researching and developing a new version of the Scratch programming language to be called ScratchJr, designed specifically for early childhood education (K-2). The current version of Scratch, which is widely implemented, is intended for ages 8-16 and is not developmentally appropriate for young children. This work will provide research-based evidence regarding young children's abilities to use an object-oriented programming language and to study the impact this has on the children's learning of scientific concepts and procedures. The team will develop ScratchJr in an iterative cycle, testing it in both in the Devtech lab at Tufts and the Eliot Pearson lab school and with a wider network of early childhood partners. At the end of the three-year project, ScratchJr will have been tested with approximately 350 students in K-2, 40 parents, and 58 early childhood educators. ScratchJr will have three components: 1) a developmentally appropriate interface, with both touch screen and keyboard/mouse options; 2) an embedded library of curricular modules with STEM content to meet federal and state mandates in early childhood education; and 3) an on-line resource and community for early childhood educators and parents. The research questions focus on whether ScratchJr can help these young children learn foundational knowledge structures such as sequencing, causality, classification, composition, symbols, patterns, estimation, and prediction; specific content knowledge; and problem solving skills. This interdisciplinary proposal makes contributions to the fields of learning technologies, early childhood education and human computer interaction. ScratchJr has the potential for broad implementation in both formal and informal settings.
The ScratchEd project, led by faculty at the Massachusetts Institute of Technology and professionals at the Education Development Center, is designing, developing, and studying an innovative model for professional development (PD) of teachers who use the Scratch computer programming environment to help their students learn computational thinking. The fundamental hypothesis of the project is that engagement in workshops and on-line activities of the ScratchEd professional development community will enhance teacher knowledge about computational thinking, their practice of design-based instruction, and their students' learning of key computational thinking concepts and habits of mind. The effectiveness of the ScratchEd project is being evaluated by research addressing four specific questions: (1) What are the levels of teacher participation in the various ScratchEd PD offerings and what do teachers think of these experiences? (2) Do teachers who participate in ScratchEd PD activities change their use of Scratch in classroom instruction to create design-based learning opportunities? (3) Do the students of teachers who participate in the ScratchEd PD activities show evidence of developing an understanding of computational thinking concepts and processes? (4) When the research instruments developed for the evaluation are made available for teachers in the Scratch community to use for self-evaluation, how do teachers make use of them? Because both computational thinking and design-based instruction are complex activities, the project research is using a combination of survey, interview, and artifact analysis methods to answer the questions. The ScratchEd professional development and research work will provide important insight into the challenge of helping teachers create productive learning environments for development of computational thinking. Those efforts will also yield a set of evaluation tools that can be integrated into the ScratchEd resources and used by others to study development of computational thinking and design-based instruction.
