New teachers are common in the teaching workforce (Ingersoll and Merrill 2012). All new teachers will learn about the school curriculum and school policies in their first years. New science teachers, however, need to attend to the "Next Generation of Science Standards" (NGSS Lead States 2013) as they build their instruction and knowledge…

Inquiry-based teaching promotes students' engagement in problem-solving and investigation as they learn science concepts. Current practice in science teacher education promotes the use of inquiry in the teaching of science. However, the literature suggests that many science teachers hold incomplete or incorrect conceptions of inquiry.…

This study examined how 12- and 13-year-old students' mathematics and science background knowledge affected line graph interpretations and how interpretations were affected by graph question levels. A purposive sample of 14 students engaged in think aloud interviews while completing an excerpted Test of Graphing in Science. Data were…

This study investigated the effects of the use of scaffolds in written classroom assessments through the voices of both native English speakers and English language learners from two middle schools. Students responded to assessment tasks in writing, by speaking aloud using think aloud protocols, and by reflecting in a post-assessment interview.…

Student's performance in science classrooms has continued to languish throughout the USA. Even though proficiency rates on national tests such as National Assessment of Educational Progress are higher for Caucasian students than African-Americans and Hispanics, all groups lack achieving desired proficiency rates. Further, the Next Generation…

Currently, it is not clear whether professional development staff at Informal Science Institutions (ISIs) are considering the way exhibits contribute to the social aspects of learning as described by the contextual model of learning (CML) (Falk & Dierking in "The museum experience." Whalesback, Washington, 1992; "Learning from…

Teacher learning communities are hailed by many as vehicles for reforming and elevating the professional status of teaching. While much research explores teacher community as a venue for measurable gains, our research examines the orientation of practitioner inquiry toward critical debate about effective instruction. Specifically, our study…

This study examines how the implementation of a novel curriculum, that emphasizes the use of published scientific data and media to learn about human impact and ecological function, influenced ninth-grade biology teacher (N - 36) dispositions toward using data and media in their ecology and human impact lesson plans. It explores how integration of…

This qualitative multiple-comparative case study investigates (1) The reported experiences and impressions of four pre-service teachers (PTs) on practicum placement in four different classrooms (grades 1-9) where a new Steps to Inquiry (SI) framework was being utilized to support students conducting open inquiry; (2) The relative dispositions of…

Anecdotal accounts from science educators suggest that few teachers are teaching science as inquiry. However, there is little empirical evidence to support this claim. This study aimed to provide evidence-based documentation of the state-of-use of inquiry-based instruction and explicit instruction about nature of science (NOS). We examined the…

Invasive species, commonly known as "invasives," are nonnative plants, animals, and microbes that completely take over and change an established ecosystem. The consequences of invasives' spread are significant. In fact, many of the species that appear on the Endangered Species list are threatened by invasives. Therefore, the topic of invasive…

The concept of energy is central to all the science disciplines, seamlessly connecting science, technology, and mathematics. For high school and upper middle school teachers, this compendium comprises inquiry-based activities, lesson plans, and case studies designed to help teach increased awareness of energy, environmental concepts, and the…

This paper compares and contrasts the impacts of three professional development designs aimed at middle school Earth science teachers on how teachers plan and enact instruction. The designs were similar in their alignment to research-based practices in science professional development: each design was of an extended duration and time span,…

Although teachers are engaged in many field-trips, they seldom have the pedagogical knowledge and experience to enact them. This article presents an effort to support reflective practice of teachers in the outdoors. The teaching experience of five pre- and in-service teachers included preparation for teaching in the outdoors, designing learning…
