The Next Generation Science Standards (NGSS) reflect an ambitious vision for science education where students investigate phenomena or solve problems through using and applying disciplinary core ideas in concert with science and engineering practices and crosscutting concepts. Because the NGSS are so different from prior standards, the need for high-quality curriculum materials is especially great. As new curricula go to scale, it will be important to conduct evidence-based research on their efficacy. We conducted a randomized experiment to examine the efficacy of a widely available NGSS-designed middle school curriculum for improving seventh grade students’ learning in physical science. A hierarchical linear modeling approach was applied to analyze student learning outcomes as measured by an NGSS-aligned assessment. Initial findings demonstrate evidence of promise of the curriculum materials for supporting three-dimensional teaching and learning. The findings provide support for further research on NGSS-designed materials at other grade levels and within other science domains.

Divergent Representations of Africa: A Qualitative Analysis of Georgia Social Studies Textbooks
The Georgia Department of Education has clearly defined standards for learning about Africa in the seventh grade. However, there exists great variation in how textbooks present this material and address these standards. Using a qualitative content analysis approach, we assess the presentation of Africa in three widely used Georgia social studies textbooks. We document and analyze coverage of Africa across Georgia’s seventh grade world studies learning domains. Our research demonstrates: 1) that, despite widespread calls for decolonization of education and strengthening of multicultural education, Euro-American perspectives on Africa are still prevalent; 2) textbooks vary widely on how they choose to address the social studies standards for Africa; and 3) negative stereotypes of Africa and its peoples continue to be reaffirmed, to the detriment of Georgia students. Lastly, our research also contributes to larger conversations on the utility of content analysis as a methodology for understanding educational practices.

Introduction: Learning standards are a crucial determinant of computer science (CS) education at the K-12 level, but they are not often researched despite their importance. We sought to address this gap with a mixed-methods study examining state and national K-12 CS standards. Research Question: What are the similarities and differences between state and national computer science standards? Methods: We tagged the state CS standards (n = 9695) according to their grade band/level, topic, course, and similarity to a Computer Science Teachers Association (CSTA) standard. We also analyzed the content of standards similar to CSTA standards to determine their topics, cognitive complexity, and other features. Results: We found some commonalities amidst broader diversity in approaches to organization and content across the states, relative to the CSTA standards. The content analysis showed that a common difference between state and CSTA standards is that the state standards tend to include concrete examples. We also found differences across states in how similar their standards are to CSTA standards, as well as differences in how cognitively complex the standards are. Discussion: Standards writers face many tensions and trade-offs, and this analysis shows how – in general terms – various states have chosen to manage those trade-offs in writing standards. For example, adding examples can improve clarity and specificity, but perhaps at the cost of brevity and longevity. A better understanding of the landscape of state standards can assist future standards writers, curriculum developers, and researchers in their work.more » « less

Abstract: The study examines how Dynamic Equilibrium (DE) is represented in science national standards and textbooks for high-school biology, chemistry, and physics in the US and Israel. DE, a crucial concept in understanding dynamic systems, is inconsistently represented across educational materials and students encounter difficulties learning about DE. Analyzing 17 textbooks and national standards, the research combines quantitative and qualitative content analysis to assess the frequency and nature of presentation of DE-related phenomena. The study identifies 256 DE-related phenomena, comprising 14% of all phenomena that are studied in science. The primary systems approach used is System Dynamics, which focuses on stocks and rates of flow at one description level. The main representational format is verbal, and computational models are scarcely used. Differences across disciplines and between countries were found. These findings emphasize the need for powerful representations of DE to enhance students' understanding of dynamic systems and improve science education.more » « less

Abstract Engineering design has been widely implemented in K-12 curricula to cultivate future workforce. In this study, seventh-grade students (N = 38) participated in theSolarizing Your Schoolcurriculum, an action-oriented program where they engaged in engineering design processes to tackle a real-world problem related to renewable energy adoption. The study sought to explore how students balanced constraints and criteria in engineering design. Over a five-day period, seventh-grade students developed plans for adopting solar energy on their school campus and simulated the plan on a technology-enhanced epistemic tool, Aladdin (https://intofuture.org/aladdin.html). Data was collected through design artifacts, log data from design processes, and surveys about their learning experience. Three distinct patterns of balancing design criteria and constraints emerged, including designing for practice, for performance, and for irrelevant goals. The group who designed for practice gave priority to criteria and constraints recorded a higher level of design performance. The study underscores the benefits of integrating action-oriented learning opportunities via engineering design processes in science education.more » « less

A major challenge for elementary STEM teacher educators is incorporating social justice considerations across the span of professional program coursework. Recognizing that standards and policy documents are pressing for diversity and inclusion in STEM education, there is a growing need to support preservice teachers’ learning about critical theories and how to develop an equitable vision of teaching. This paper describes ongoing research on our University’s elementary STEM teacher education program. We focus our discussion on instrument development and the methods we used for eliciting preservice teachers’ understandings of equity and diversity issues related to teaching STEM content. We designed a number of math, science, and technology scenarios in tandem, as means of building coherence across disciplinary boundaries; this report focuses on math teaching and learning.more » « less
