Zoo and aquarium educators are increasingly providing educationally rigorous programs that connect their animal collections with curriculum standards in mathematics as well as science. Partnering with zoos and aquariums is a powerful way for teachers to provide students with more opportunities to observe, collect, and analyze scientific data. This…

What happens when children and scientists learn together? A partnership is formed, that's what! This article describes how a university scientist and a teacher teamed up with a local fourth-grade teacher to provide a unique opportunity for students to observe real scientists at work and enhance their knowledge of weather at the same time. The…

Drawing from a large efficacy study in upper elementary science, this report had three purposes: First to examine the quality of teachers' content-pedagogical knowledge in upper elementary science; second, to analyze the relationship between teacher knowledge and their assessment practice; and third, to study the relationship between teacher…

This study explored the impact of a reflective teaching method on pre-service elementary teachers' conceptual understanding of the lunar phases, reasons for seasons, and simple electric circuits. Data were collected from 40 pre-service elementary teachers about their conceptual understanding of the lunar phases, reasons for seasons and day…

The fundamental factor of environmental education is teachers who are well-informed about environmental issues. This research aimed to determine prospective Turkish elementary science teachers' knowledge level about causes, consequences and reducing of the greenhouse effect and to investigate the effect of gender, information source and membership…

The present study piloted a survey-based measure of Opportunity to Learn (OTL) and Academic Language Exposure (ALE) in fourth grade science classrooms that sought to distinguish teacher practices with ELL (English language learner) and non-ELL students. In the survey, participant teachers reported on their instructional practices and the context…

The Trends in International Mathematics and Science Study (TIMSS) Video Study explored instructional practices in the United States (US) in comparison with other countries that ranked higher on the 1999 TIMSS assessment, and revealed that 8th grade science teachers in the US emphasize activities over content during lessons (Roth et al.…

The purpose of this research was to evaluate a collaborative concept-mapping technique that was integrated into coteaching in fourth-grade science classes in order to examine students' performance and attitudes toward the experimental teaching method. There are two fourth-grade science teachers and four classes with a total of 114 students…

The relative positions of the sun, moon, and earth, their movements, and their relationships are abstract and difficult to understand astronomical concepts in elementary school science. This study proposes a three-dimensional (3-D) virtual reality (VR) model named the "Sun and Moon System." This e-learning resource was designed by…

This article reports data from a 2-year longitudinal study on cooperative learning in school science. The study reported the effects of cooperative learning in science on science attainment, effective development and social connectedness, and interactions during transition from elementary to high school in rural and urban school settings. The…

The learning cycle is a way to structure inquiry in school science and occurs in several sequential phases. A learning cycle moves children through a scientific investigation by having them first explore materials, then construct a concept, and finally apply or extend the concept to other situations. Why the learning cycle? Because it is a…

Children personally construct explanations of natural phenomena, some of which differ from currently accepted scientific explanations. The replacement of personal explanations with scientific explanations, as well as the development of concrete, formal, and post-formal reasoning patterns, requires self-regulation in which alternative explanations…

For farmers and gardeners, slugs and snails may be serious pests that will limit the amount of harvest, but for a child, they represent a world to be explored. To teachers, however, invertebrates are tools for broadening students' understanding about animals, the connections between animals and habitats or plants, and an engaging subject to write…

Many recipes for elementary science activities suggest making carbon dioxide from baking soda and vinegar; however, they often do not give exact measurements of the ingredients. The author was able to turn this "drawback" into a plus by challenging her fifth-grade students to find the "ultimate fizz"--i.,e., "What amount of baking soda added to a…

Seeing, touching, smelling, hearing, and learning! The authors observed that their English Language Learner (ELL) students achieved a deeper understanding of the properties of matter, as well as enhanced vocabulary development, when they were guided through inquiry-based, multisensory explorations that repeatedly exposed them to words and…
