Impact of Model‐based Science Curriculum and Instruction on Elementary Students' Explanations for the Hydrosphere

Developing scientific literacy about water systems is critical for K‐12 students.

Year: 
2018
Short Description: 
Scientific modeling affords opportunities for students to develop representations, make their ideas visible, and generate model‐based explanations for complex natural systems like the water cycle. This study describes a comprehensive evaluation of a 5‐year, design‐based research project focused on the development, implementation, revision, and testing of an enhanced, model‐centered version of the Full Option Science System (FOSS) Water (2005) unit in third grade classrooms.

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.

What Matters for Urban Adolescents’ Engagement and Disengagement in School: A Mixed-Methods Study

This study uses a mixed-method sequential exploratory design to examine influences on urban adolescents’ engagement and disengagement in school. First, we interviewed 22 middle and high school students who varied in their level of engagement and disengagement. Support from adults and peers, opportunities to make choices, and external incentives aligned with greater engagement. In contrast, a strict disciplinary structure, an irrelevant and boring curriculum, disengaged peers, and lack of respect by adults coincided with greater disengagement.

Beyond Classroom Academics: A School-Wide and Multi-Contextual Perspective on Student Engagement in School

School engagement researchers have historically focused on academic engagement or academic-related activities. Although academic engagement is vital to adolescents’ educational success, school is a complex developmental context in which adolescents also engage in social interactions while exploring their interests and developing competencies. In this article, school engagement is re-conceptualized as a multi-contextual construct that includes both academic and social contexts of school.

Using online telescopes to explore exoplanets from the physics classroom

The search for habitable planets offers excellent opportunities to advance students’ understanding of core ideas in physics, including gravity and the laws of motion, the interaction of light and matter, and especially the nature of scientific inquiry. Thanks to the development of online telescopes, students can detect more than a dozen of the known exoplanets from the classroom, using data they gather, assess, and interpret for themselves. We present a suite of activities in which students apply basic physics concepts to their investigations of exoplanets.

Integrating Geospatial Technologies in Fifth-Grade Curriculum: Impact on Spatial Ability and Map-Analysis Skills

This study explores the effects of geographic information systems (GIS) curriculum on fifth-grade students' spatial ability and map-analysis skills. A total of 174 students from an urban public school district and their teachers participated in a quasi-experimental design study. Four teachers implemented a GIS curriculum in experimental classes over six weeks while three teachers continued with regular teaching in control classes. Both groups completed pre- and post-tests measuring spatial ability and map-analysis skills.
