The 8 Elements of Inclusive STEM High Schools: Findings from the STEM School Study

The STEM School Study (S3) team sat down with inclusive STEM school leaders from over 25 inclusive STEM schools and asked them to describe the parts of their schools that are essential to their school models. We found that while STEM schools vary in many ways, there are eight major Elements common to them all. Each Element is comprised of a number of components and together, they illustrate what STEM schools are and lay the groundwork for understanding how STEM schools work to achieve their goals.

Towards Domain-Independent Assessment of Elementary Students’ Science Competency using Soft Cardinality

Automated assessment of student learning has become the subject of increasing attention. Students’ textual responses to short answer questions offer a rich source of data for assessment. However, automatically analyzing textual constructed responses poses significant computational challenges, exacerbated by the disfluencies that occur prominently in elementary students’ writing. With robust text analytics, there is the potential to analyze a student’s text responses and accurately predict his or her future success.

Assessing Elementary Students' Science Competency with Text Analytics

Real-time formative assessment of student learning has become the subject of increasing attention. Students’ textual responses to short answer questions offer a rich source of data for formative assessment. However, automatically analyzing textual constructed responses poses significant computational challenges, and the difficulty of generating accurate assessments is exacerbated by the disfluencies that occur prominently in elementary students’ writing. With robust text analytics, there is the potential to accurately analyze students’ text responses and predict students’ future success.

SketchMiner: Mining Learner-Generated Science Drawings with Topological Abstraction

Mining learner generated sketches holds significant potential for acquiring deep insight into learners’ mental models. Drawing has been shown to benefit both learning outcomes and engagement, and learners’ sketches offer a rich source of diagnostic information. Unfortunately, interpreting learners’ sketches—even sketches comprised of semantically grounded symbols—poses significant computational challenges.

Scaffolding Argumentation about Water Quality: A Mixed-method Study in a Rural Middle School

A common way for students to develop scientific argumentation abilities is through argumentation about socioscientific issues, defined as scientific problems with social, ethical, and moral aspects. Computer-based scaffolding can support students in this process. In this mixed method study, we examined the use and impact of computer based scaffolding to support middle school students’ creation of evidence-based arguments during a 3-week problem-based learning unit focused on the water quality of a local river.

Short Description

In this mixed method study, we examined the use and impact of computer based scaffolding to support middle school students’ creation of evidence-based arguments during a 3-week problem-based learning unit focused on the water quality of a local river. We found a significant and substantial impact on the argument evaluation ability of lower-achieving students, and preliminary evidence of an impact on argument evaluation ability among low-SES students. We also found that students used the various available support—computer-based scaffolding, teacher scaffolding, and groupmate support—in different ways to counter differing challenges. We then formulated changes to the scaffolds on the basis of research results.

A Pilot Meta-Analysis of Computer-Based Scaffolding in STEM Education

This paper employs meta-analysis to determine the influence of computer-based scaffolding characteristics and study and test scorequality on cognitive outcomes in science, technology, engineering, and mathematics education at the secondary, college, graduate, and adult levels.

A Blended Professional Development Program to Help a Teacher Learn to Provide One-to-One Scaffolding

Argumentation is central to instruction centered on socio-scientific issues (Sadler & Donnelly in International Journal of Science Education, 28(12), 1463–1488, 2006. doi:10.1080/09500690600708717). Teachers can play a big role in helping students engage in argumentation and solve authentic scientific problems. To do so, they need to learn one-to-one scaffolding—dynamic support to help students accomplish tasks that they could not complete unaided.

Exploring Ecosystems from the Inside: How Immersive Multi-user Virtual Environments Can Support Development of Epistemologically Grounded Modeling Practices in Ecosystem Science Instruction

Recent reform efforts and the next generation science standards emphasize the importance of incorporating authentic scientific practices into science instruction. Modeling can be a particularly challenging practice to address because modeling occurs within a socially structured system of representation that is specific to a domain. Further, in the process of modeling, experts interact deeply with domain-specific content knowledge and integrate modeling with other scientific practices in service of a larger investigation.
