Science and Children - November 2006

Kids who do hands-on science are eager to talk about, write about, and read about their experiences. Those of us who have tried it know that this is true, but it's still one of the best-kept secrets of the world of education! Through the project "A Head Start on Science" at California State University, Long Beach, educators have been working with Head Start teachers, children and their parents since 1995, and their observations have convinced them that is referred to as "sense of wonder" science consistently opens the door for teachers who are anxious to have their children meet the many language and literacy goals and standards called for at every level.

In Alandeom Oliveira & Molly Weinburgh (Eds.), ASTE Monograph - Science Teacher Preparation in Content-Based Second Language Acquisition. (pp. 137-150).

  Across a 4-year period, a large urban California school district developed and implemented a blended inquiry science and English Language Development (ELD) program in an effort to provide their English language learners opportunities to develop proficiency in English through participation in inquiry-based science. The resulting, “science/ELD blended program,” utilized a combined science/ELD lesson plan format to structure and guide teachers’ efforts to use science as the context for language development. In this paper we describe the development and outcomes of this program. A sample that included 3 school principals, 60 teachers, and over 2,000 students in Kindergarten through 5th grade provides windows into the effectiveness of the program. Implementation of this program resulted in enhanced status for science, increases in students’ English oral language use, and changes in teachers’ understanding of their own teaching practice. Additionally, participating students’ English and science achievement, compared to a similar group of students who were using the district’s established English language development curriculum, demonstrates modest, but statistically significant improvement. Results from this study suggest that restricting instructional minutes for science to provide additional time for ELD and English language arts may be unnecessary. Rather, allowing consistent time for science instruction that incorporates ELD instruction along with inquiry science experiences may provide the authentic and purposeful context students need to develop new language without restricting access to science content.

  Limited class time devoted to science, children’s limited science understanding (as compared to language arts and math), and teachers’ perceived lack of confidence and preparation for science teaching in early childhood classrooms is well documented. Many attribute these short-comings, in part, to limited science-related professional development opportunities available to teachers of young children. However, there are now increased efforts to support preschool teachers’ implementation of science, including the A Head Start on Science a five-day professional development institute designed to help early childhood educators to provide quality science learning experiences. We used the Preschool Teacher Attitudes and Beliefs toward Science Teaching (P-TABS) questionnaire (Maier, Greenfield, and Bulotsky-Shearer, 2013) to investigate Teacher Comfort and Child Benefit ratings of 49 pre-school teachers that elected to participate in our HSOS summer institute. These participants came from many different school sites, but all teach within a densely populated and ethnically diverse urban area within Southern California. Participating teachers increased significantly (p<0.0001) in their comfort with teaching science; their valuing of the child benefits of science increased, although not significantly.

  This paper presents findings from a 4-year project that developed and implemented a blended inquiry science and English Language Development (ELD) program in a large urban California school district. The sample included over 2,000 students in Kindergarten through 5th grade. Participating students' English and science achievement was compared to a similar group of students who were using the district’s established English language development curriculum. Student performance on state-mandated English and science assessments were analyzed using Mann–Whitney U tests for overall performance and by number of years of treatment. Modest but statistically significant improvement was found for students who participated in the blended program. Results from this study suggest that restricting instructional minutes for science to provide additional time for ELD and English language arts may be unnecessary. Rather, allowing consistent time for science instruction that incorporates ELD instruction along with inquiry science experiences may provide the authentic and purposeful context students need to develop new language without restricting access to science content.

  This paper explores one district's attempt to implement a blended science and English Language Development (ELD) elementary program, designed to provide English language learners opportunities to develop proficiency in English through participation in inquiry-based science. This process resulted in blended program that utilized a combined science/ELD lesson plan format to structure and guide teachers’ efforts to use science as the context for language development. Data, collected throughout the first two years of the program, include teacher-generated lesson plans, observation notes, and interviews with teachers and principals. The process by which the blended program was developed, the initial implementation of the program, the resulting science/ELD lesson plan format, and teachers' perceptions about the program and its impact on their students are described.

For the littlest scientists, the whole wide world can be a laboratory for learning.Nurture their natural curiosity with A Head Start on Science, a treasury of 89 hands-on science activities specifically for children ages 3 to 6.

The activities are grouped into seven stimulating topic areas: the five senses, weather, physical science, critters, water and water mixture, seeds, and nature walks.

Because the activities have been field-tested by more than a thousand Head Start teachers over 10 years, you’ll find this collection unusually easy to use in a variety of settings, including elementary schools, pre-K programs, and day care. In addition to clear background and a helpful materials list, you get step-by-step procedures and help preparing for comments and questions children may pose. Each activity ends with a reproducible Family Science Connection—in both English and Spanish—to send home so the whole family can share a learning experience that’s both simple and pleasant.

Thanks to a focus on the fun of exploration and discovery, children probably won’t be the only ones who find these activities irresistible. As Editor Bill Ritz writes in the Introduction, “We hope your own sense of wonder will be heightened as you observe children and as their curiosity leads them to answer their own questions about everything they see, hear, smell, and touch.”

Nurture curiosity and even joy in the youngest scientists. The 24 inquiry-based lessons in this lively collection show you how. The activities are organized into sections on animals, plants, and nature walks. Rather than merely presenting science facts to 3- to 7-year-olds, you’ll prompt them to make discoveries of their own. They’ll explore critter camouflage, probe pumpkin insides, make bird feeders, and more.

A Head Start on Life Science is as easy to use as it is inspiring. Each lesson includes lists of learning objectives and required materials, relevant background to help you prepare, plus at-home activities written in English and Spanish. Connections to multiple subjects—including reading, writing, math, dramatic play, and art—let you offer related learning opportunities. Extensions help you relate the science to children’s everyday lives and encourage them to explore with their families.

You can use A Head Start on Life Science in preschools, elementary schools, informal science settings, home schools—anywhere you want to engage children in meaningful, longer-lasting science learning. The book is a follow-up to NSTA’s popular A Head Start on Science. Like that treasury of science activities, this collection is designed to heighten children’s sense of wonder about the natural world.
