The Efficacy of Educative Curriculum Materials to Support Geospatial Science Pedagogical Content Knowledge

Publications

Teaching and learning about geospatial aspects of energy resource issues requires that science teachers apply effective science pedagogical approaches to implement geospatial technologies into classroom instruction. To address this need, we designed educative curriculum materials as an integral part of a comprehensive middle school energy resources science curriculum. We examined teachers’ perceived impact of the curriculum materials to support their pedagogical content knowledge related to teaching science with geospatial technologies. Results indicated that the educative curriculum materials

Design Fixation

Publications

The purpose of this article is to provide awareness of the danger of design fixation and promote the uses of brainstorming early in the design process--before fixation limits creative ideas. The authors challenged technology teachers to carefully limit the use of design examples too early in the process and provided suggestions for facilitating brainstorming sessions to help generate innovative ideas. The authors are not suggesting that teachers never provide design examples; in fact, this article highlights techniques for providing students with authentic examples and the benefits of this

Persistent Teaching Practices after Geospatial Technology Professional Development

Publications

This case study described teachers with varying technology skills who were implementing the use of geospatial technology (GST) within project-based instruction (PBI) at varying grade levels and contexts 1 to 2 years following professional development. The sample consisted of 10 fifth- to ninth-grade teachers. Data sources included artifacts, observations, interviews, and a GST performance assessment and were analyzed using a constant comparative approach. Teachers’ teaching actions, beliefs, context, and technology skills were categorized. Results indicated that all of the teachers had high

A Framework for Aligning Needs, Abilities and Affordances to Inform Design and Practice of Educational Technologies

Publications

This paper addresses the need for enhancing our awareness of user‐centered design in educational technology through a more explicit and systematic alignment between the needs of educational technology users (learners and educators) and the affordances provided by the technology. First, we define the term “affordance” and discuss it from the perspectives of cognitive psychology and user interaction design. Next, we propose a taxonomy of functional affordances that builds on prior research and reflects the current trends in the design of educational technologies. The paper is concluded with an

3D Fossils for K-12 Education: A Case Example Using the Giant Extinct Shark Carcharocles Megalodon

Publications

Fossils and the science of paleontology provide a charismatic gateway to integrate STEM teaching and learning. With the new Next Generation Science Standards (NGSS), as well as the exponentially increasing use of three-dimensional (3-D) printing and scanning technology, it is a particularly opportune time to integrate a wider variety of fossils and paleontology into K–12 curricula. We describe a curricular prototype that integrates all four components of STEM (Science, Technology, Engineering, Math) into authentic research using dentitions of the Neogene giant shark Megalodon (Carcharocles

Empowering Middle School Students to Create Data-enabled Social Apps

Publications

MIT App Inventor has enabled middle school students to learn computing while creating their own apps-including apps that serve community needs. However, few resources exist for building apps that gather and share data. There is a need for new tools and instructional materials for students to build data-enbaled, community-focused apps. We developed an extension for App Inventor, called AppleVis, which allows app-makers to publish and retrieve data from our existing web-based collaborative data visualization platform.

Eliciting Algebraic Reasoning with Hanging Mobiles

Publications

How algebraic reasoning can be fostered within the important big idea of equivalence is demonstrated using hanging mobiles. A concrete-representational-abstract approach is used, without any formal algebraic symbolism, to elicit algebraic reasoning and higher-order thinking.

Preparing Teachers to Engage Rural Students in Computational Thinking through Robotics, Game Design, and Culturally Responsive Teaching

Publications

This article examines teacher preparation and teacher change in engineering and computer science education. We examined culturally responsive teaching self-efficacy (CRTSE), culturally responsive teaching outcome expectancy (CRTOE) beliefs, and attitudes toward computational thinking (CT) as teachers participated in one of three treatment groups: robotics only, game design only, or blended robotics/game design. Descriptive data revealed that CRTSE gain scores were higher in the robotics only and blended contexts than in the game design only context. However, CRTOE beliefs were consistent

Relationship of Middle School Student STEM Interest to Career Intent

Publications

Understanding middle school students’ perceptions regarding STEM dispositions, and the role attitudes play in establishing STEM career aspirations, is imperative to preparing the STEM workforce of the future. Data were gathered from more than 800 middle school students participating in a hands-on, real world application curriculum to examine the relationship of the students’ interest in STEM and their intentions to pursue a career in a STEM field. Among the middle school students who completed surveys for the MSOSW project, 46.6% expressed a desire to pursue a career in STEM at the time of the

Modeling and Simulation: How Everything seems to Form and Grow

Publications

The ideas in this article resulted from many years of research in engineering, physics, computer, and cognitive sciences, as well as teaching experience in college and secondary schools. While its main purpose is to discuss the universality of modeling and simulation process and its pedagogical use in teaching, there are several conclusions to be drawn.
