This paper will explain what a reading teacher learned from working with a group of first-grade struggling readers in a series of shared-book experience classes. The shared-book experience approach used a variety of science-themed books that were aligned with the first-grade curriculum and appropriate for beginning readers. Considering the…

When studying informal science programs, researchers often overlook the opportunities enabled and constrained in each program and the practices reinforced for participants. In this case study, I examined the normative scientific practices reinforced in one-week-long "Herpetology" (the study of reptiles and amphibians) program for…

The "Framework for K-12 Science Education" (NRC, 2012) and "Next Generation Science Standards" (NGSS Lead States, 2013) stress that in addition to disciplinary core ideas (content), students need to engage in the practices of science and develop an understanding of the crosscutting concepts such as cause and effect, systems,…

This qualitative study clarifies opinion of 32 European volunteer youth leaders on concepts of competence, fewer opportunities and enlargement strategies on competence of fewer opportunities. Leaders underline main competencies as follows: tongue, languages, mathematical, digital, learning, social, entrepreneurship, cultural. Key competences are…

Multiple-choice questions are an important part of large-scale summative assessments, such as the advanced placement (AP) chemistry exam. However, past AP chemistry exam items often lacked the ability to test conceptual understanding and higher-order cognitive skills. The redesigned AP chemistry exam shows a distinctive shift in item types toward…

We present a guided-inquiry biology lesson, using the plant-rhizobium symbiosis as a model system. This system provides a rich environment for developing connections between the big ideas in biology as outlined in the College Board's new AP Biology Curriculum. Students gain experience with the practice of scientific investigation, from…

The purpose of this investigation was to explore how aspects of identity, perceived levels of controversy, and the strength of a student's attachment to their controversial identity relate to conceptual understanding and knowledge acquisition during socioscientific issues (SSI) based instruction in a biology classroom. The knowledge gained from…

Early childhood educators teach science to all students, including students with disabilities. Strategies for accommodating students with disabilities in science, including familiarity with equitable frameworks such as Universal Design for Learning (UDL) are therefore a critical aspect of early childhood teacher candidates' pedagogical content…

The "Next Generation Science Standards" provide opportunities for students to experience the link between science and engineering. In the December 2011 issue of "Science and Children," Rodger Bybee explains: "The relationship between science and engineering practices is one of complementarity. Given the inclusion of…

This paper reports the results of a study aimed at exploring the advantages of dynamic visualization for the development of better understanding of molecular processes. We designed a technology-enhanced curriculum module in which high school chemistry students conduct virtual experiments with dynamic molecular visualizations of solid, liquid, and…

Diverse implicit cognitive elements seem to support but also constrain reasoning in different domains. Many of these cognitive constraints can be thought of as either implicit assumptions about the nature of things or reasoning heuristics for decision-making. In this study we applied this framework to investigate college students' understanding of…

One of the great challenges to teachers both historically and contemporarily is to facilitate a classroom as a "group" of students, while concurrently attending to each "individual" student. As the profession becomes increasingly aware and sensitive to student (dis)abilities, academic giftedness, pressures of athletics and…

The central goal of this study was to characterize major patterns of reasoning exhibited by college chemistry students when analyzing and interpreting chemical data. Using a case study approach, we investigated how a representative student used chemical models to explain patterns in the data based on structure-property relationships. Our results…

Communication and critical thinking skills are integral to the undergraduate chemistry major. A bookend, two-course model has been implemented to supplement chemistry subfield knowledge with the development of these skills. The third-year course introduces the chemical literature and addresses these skills through the synthesis of a literature…

Road map problems ask students to integrate their knowledge of organic reactions with pattern recognition skills to "fill in the blanks" in the synthesis of an organic compound. Students are asked to identify familiar organic reactions in unfamiliar contexts. A practical context, such as a medicinally useful target compound, helps…
