Revealing Teacher Knowledge through Making: A Case Study of Two Prospective Mathematics Teachers

We describe an experience within mathematics teacher preparation that engages pre-service teachers of mathematics (PMTs) in Making and design practices that we hypothesized would inform their conceptual, curricular, and pedagogical thinking. With a focus on the design of new tools that can generate new possibilities for mathematics teaching and learning, this Learning by Design experience has PMTs exploring at the intersection of content, pedagogy, and Making.

The Effect of Automated Feedback on Revision Behavior and Learning Gains in Formative Assessment of Scientific Argument Writing

Application of new automated scoring technologies, such as natural language processing and machine learning, makes it possible to provide automated feedback on students' short written responses. Even though many studies investigated the automated feedback in the computer-mediated learning environments, most of them focused on the multiple-choice items instead of the constructed response items. This study focuses on the latter and investigates a formative feedback system integrated into an online science curriculum module teaching climate change.

Qualitative graphing in an authentic inquiry context: How construction and critique help middle school students to reason about cancer

Inquiry instruction often neglects graphing. It gives students few opportunities to develop the knowledge and skills necessary to take advantage of graphs, and which are called for by current science education standards. Yet, it is not well known how to support graphing skills, particularly within middle school science inquiry contexts. Using qualitative graphs is a promising, but underexplored approach.

Validating a Model for Assessing Science Teacher’s Adaptive Expertise with Computer-Supported Complex Systems Curricula and Its Relationship to Student Learning Outcomes

The success of the Next Generation Science Standards (NGSS) and similar reforms is contingent upon the quality of teaching, yet the shifts in teaching practice required are substantial. In this study, we propose and validate a model of adaptive expertise needed for teachers to successfully deliver NGSS-informed computer-supported complex systems curricula in high school science classrooms.

Non-visual Perception of Lines on a Multimodal Touchscreen Tablet

While text-to-speech software has largely made textual information accessible in the digital space, analogous access to graphics still remains an unsolved problem. Because of their portability and ubiquity, several studies have alluded to touchscreens as a potential platform for such access, yet there is still a gap in our understanding of multimodal information transfer in the context of graphics. The current research demonstrates feasibility for following lines, a fundamental graphical concept, via vibrations and sounds on commercial touchscreens.

Integrating a Space for Teacher Interaction into an Educative Curriculum: Design Principles and Teachers' Use of the iPlan Tool

Implementation of reform curricula requires teachers to adopt new approaches to teaching. Research has provided promising results about the influence of educative curriculum on teachers’ learning and instruction. However, this approach generally focuses on teachers as isolated learners. Using a design-based research approach, the authors developed a web-based tool, iPlan, which provides access to educative curriculum materials in an online interactive learning platform.

Exploring Students’ Experimentation Strategies in Engineering Design Using an Educational CAD Tool

Experimentation is one of the important strategies used in engineering design to understand the relationship between relevant variables so that they can be manipulated to generate optimized solution for a particular problem or design. The understanding of students’ experimentation strategies allows educators to help students improve their design experiments by providing scaffolds or guidance. The purpose of this study is to investigate students’ experimentation strategies while they work on a design challenge.

The Role of Simulation-Enabled Design Learning Experiences on Middle School Students’ Self-generated Inherence Heuristics

In science and engineering education, the use of heuristics has been introduced as a way of understanding the world, and as a way to approach problem-solving and design. However, important consequences for the use of heuristics are that they do not always guarantee a correct solution. Learning by Design has been identified as a pedagogical strategy that can guide individuals to properly connect science learning via design challenges.

Automated text scoring and real‐time adjustable feedback: Supporting revision of scientific arguments involving uncertainty

This paper describes HASbot, an automated text scoring and real‐time feedback system designed to support student revision of scientific arguments. Students submit open‐ended text responses to explain how their data support claims and how the limitations of their data affect the uncertainty of their explanations. HASbot automatically scores these text responses and returns the scores with feedback to students. Data were collected from 343 middle‐ and high‐school students taught by nine teachers across seven states in the United States.
