Elementary teachers often avoid the struggle of matching a science activity to a specific standard by using a lesson planning process known as Understanding by Design (UBD) (Wiggins and McTighe 2005). A main tenet of the UBD model involves starting at the end rather than at the beginning of the planning process. By starting at the end and visiting…

Teachers have an important role in raising environmental awareness in individuals through environmental education and thus preventing environmental problems. For this reason, the self-efficacy level of teachers in environmental education is crucial. This study aims at determining the self-efficacy levels of geography and biology teachers and…

Science education is changing. With the release of the Next Generation Science Standards [NGSS], K-12 teachers are expected to engage students in the practices of scientists and engineers to make sense of disciplinary core ideas and crosscutting concepts (NGSS Lead States, 2013). Simultaneously, there is a push to expose students to Science,…

During the preschool years children develop many new skills, including gross motor abilities, which serve as a foundation for school readiness skills in areas such as language, socialization and cognition. Like other domains, motor skill development does not happen without practice opportunities. That is, it requires multiple opportunities whereby…

Among the fields that particularly lack images of diverse participants are those of science, technology, engineering, and math, fields captured under the acronym STEM. Often in STEM fields, images and experiences of deaf and hard of hearing children, children of color, and young women are rare or absent altogether, with the result that these…

This article presents a qualitative study, descriptive-interpretive in profile, of the effectiveness in learning about the nature of science (NOS) of an activity relating to the historical controversy between Pasteur and Liebig on fermentation. The activity was implemented during a course for pre-service secondary science teachers (PSSTs)…

Chemistry lesson should be supported with experiments to understand the lecture effectively. For safety laboratory environment and to prevent laboratory accidents; chemical substances' properties, working principles for chemical substances' usage should be learnt. Aim of the present study was to analyze the effect of experiments which depend on…

Despite Singapore's excellent science achievements in international benchmark tests such as the Trends in International Mathematics and Science Study (TIMSS) and Programme for International Student Assessment (PISA), little is known about Singaporean children's (aged 4-8) emerging science conceptions as formal science schooling begins at Grade 3…

Topical science is about developing an awareness of science issues in the news and the importance of science stories that affect pupils' lives and the world around them. It is about making science relevant for pupils and engaging them in the subject. The author explores how children can be engaged and inspired through topical science. The idea of…

A laboratory experiment is described that extracts the tetrapyrrolic teal-colored biliverdin IXa, as its dimethyl ester, from commercially available emu eggshells. The extraction of ~10 mg samples of biliverdin is simple and requires two 3 h lab periods: A two-step acid digestion and liquid-liquid extraction, followed by short silica gel flash…

When new concepts, models, or theories are introduced in a course, their presentation should be accurate, even if depth is not the goal. In a recent publication in this Journal, the Woodward-Hoffmann rules were invoked in the context of a new laboratory experiment, but the associated description was inaccurate. Here we aim to clarify the…

Reading provides a unique window into the history and nature of science and the norms of scientific communication and supports students in developing critical-reading skills in engaging ways. Effective use of reading promotes a spirit of inquiry and an understanding of science concepts while also addressing expectations of the Common Core State…

This research used a quasiexperimental method to explore whether integrating Science Magic (SM) into 5E Learning Cycle (5ELC) in the development of teaching materials for a friction unit would impact students' learning outcomes and attitudes toward science. A total of 68 eighth-grade students were divided into experimental and control groups. The…

Science students should undertake engineering design projects and carry out scientific investigations, as recommended by the "Next Generation Science Standards" (NGSS Lead States 2013). However, studies show that students misconstrue the goals of science and engineering and are uncertain about their respective practices (Gilbert and Wade…

Biomodeling is the study of the structures and behaviors of interacting biological entities such as molecules, cells, or organisms. While physical and chemical processes give rise to various spatial and temporal structures, even the simplest biological phenomenon is infinitely more complex (Kling 2004). Over the past decade, much of biomodeling…
