Seagrass ecosystems are widespread, valuable, and threatened. We have used this system as a model to teach 3rd-7th grade students about food webs, the interconnectedness of ecosystems, ecosystem services, and the effects of human activity on coastal systems. Our objective was to increase student understanding of seagrass ecosystems and other key…

Computer science (CS) and computational thinking (a problem-solving process used by computer scientists) teach students design, logical reasoning, and problem solving--skills that are valuable in life and in any career. Computational thinking (CT) concepts such as decomposition teach students how to break down and tackle a large complex problem.…

"Great Explorations in Math and Science[R] (GEMS[R]) Space Science" is an instructional sequence for grades 3-5 that covers fundamental concepts, including planetary sizes and distance, the Earth's shape and movement, gravity, and moon phases and eclipses. Part of the "GEMS"[R] core curriculum, "GEMS[R] Space Science"…

This paper describes a qualitative case study designed to examine the challenges to effective science instruction faced by elementary teachers and examine the influence those challenges have on teachers' science teaching practices. Data were gathered through a questionnaire administered to over 240 teachers in a northern Florida school district…

Guided by a new framework, the NAEP science assessment was updated in 2009 to keep the content current with key developments in science, curriculum standards, assessments, and research. The 2009 framework organizes science content into three broad content areas. Physical science includes concepts related to properties and changes of matter, forms…

This research is distinctive in that parents' perceptions were utilised in conjunction with students' perceptions in investigating science classroom learning environments among Grade 4 and 5 students in South Florida. The What Is Happening In this Class? (WIHIC) questionnaire was modified for young students and their parents and administered to…

This study asked elementary school teachers how educational policies affected their science instruction with a majority of English language learners. The study employed a questionnaire followed by focus group interviews with 43 third and fourth grade teachers from six elementary schools in a large urban school district with high populations of…

This research project consists of a randomized experiment in St. Petersburg Catholic Schools. The question being addressed by the research is whether "Scott Foresman Science" is as effective as the current curricula being used in the participating campuses of the Roman Catholic Diocese of St. Petersburg. The research focuses on 3rd, 4th,…

In this paper, the authors' investigated whether "Scott Foresman Science" program, a year-long curriculum intended for daily use that provides a sequence of structured and supportive inquiry activities and text materials to develop students' independent investigative skills, is more effective than current science programs in five diverse…
