This article notes the convergence of recent thinking in neuroscience and grounded cognition regarding the way we understand mental representation and recollection: ideas are dynamic and multi-modal, actively created at the point of recall. Also, neurophysiologically, re-entrant signalling among cortical circuits allows non-conscious processing to…

The study aims to investigate the effect of using constructivist learning model in teaching science, especially in the subject of light: its nature, mirrors, lens, and properties, on the achievement of eighth-grade students and their scientific thinking. The study sample consisted of (136) male and female 8th graders were chosen from two basic…

Interpreting and creating graphs plays a critical role in scientific practice. The K-12 Next Generation Science Standards call for students to use graphs for scientific modeling, reasoning, and communication. To measure progress on this dimension, we need valid and reliable measures of graph understanding in science. In this research, we designed…

Citizen science programs provide opportunities for students to help professional scientists while fostering science achievement and motivation. Instruments which measure the effects of this type of programs on student motivational beliefs are limited. The purpose of this study was to describe the process of examining the reliability and validity…

Experiments are essential for both doing science and learning science. The aim of the German youth science fair, "Jugend forscht," is to encourage scientific thinking and inquiry methods such as experimentation. Based on 57 interviews with participants of the competition, this study summarises students' conceptions and steps of learning…

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…
