Citizen science has proven to be a useful paradigm both to contribute to science and to increase the public understanding of science. Thus the connection between citizen science and schools offers an interesting approach to explore. However, a lot of questions and challenges remain unclear, such as the balance between scientific and educational…

Deep science understanding is reflected in students' ability to use content and skills when making sense of the world. Assessing deep understanding requires measuring complex constructs that combine elements of content and skills. To develop valid measures of complex constructs, we need to understand how their theoretical dimensionality, reflected…

Green School intend to increase student connection to the environment, and have the potential to increase achievement through opportunities for hands-on science learning. This study utilizes publicly available data on all public schools in Maryland to examine the extent to which the Green School designation relates to changes in science…

At the time of the current global energy crisis energy awareness education in school is increasingly important. Textbooks directly helping and influencing learning play an important role in this, especially in the case of natural sciences. Thus, the aim of this research was to show how science textbooks help to educate energy awareness (EA).…

Computational thinking" (CT) is still a relatively new term in the lexicon of learning objectives and science standards. The term was popularized in an essay by Wing, who said, "To reading, writing and arithmetic, we should add computational thinking to every child's analytical ability." Agreeing with this premise, in 2013 the…

Engineering's promise to build a better world has been realized differently across the United States, often with lines of social identity determining who becomes an engineer, who benefits from engineering innovations, and who suffers devastating consequences. Many educational scholars have argued that engineering inequities are in part due to deep…

Nebraska is committed to pursuing a new vision for science education based on "A Framework for K-12 Science Education" (NRC, 2012), that advocates for rigorous, high-quality science education for all students. Following an ambitious four year timeline, Nebraska is working to develop new assessments aligned to and designed for these…

The purpose of this study was to explore the perceptions of urban secondary math and science teachers, administrators, and district personnel regarding the factors that influence secondary math and science teachers with more than five years of teaching experience to remain in urban Title I districts. The participants were interviewed to gain their…

Recent education reforms including the "Next Generation Science Standards" emphasize integrating engineering into K-12 science instruction. Although prior studies have characterized engineering design (ED) in K-12 settings, no validated protocols attempt to characterize ED integration in secondary science classrooms. The present study…

The aim of this study is to analyze the types of visual representations in primary and secondary science textbooks in Turkey. The sample of the research constitutes six textbooks prepared by private publishers for primary and secondary science courses (3rd -8 th Grade) in Turkey in 2018-2019 academic year. Document analysis design, which is one of…

There is widespread agreement that an adequate understanding of the nature of science (NOS) is a critical component of scientific literacy and a major goal in science education. However, we still do not know many specific details regarding how students and teachers learn particular aspects of NOS and what are the most important feature traits of…

This study explored the professional responsibilities of district science coordinators, their professional development (PD) experiences, the relationship between their role, responsibilities, district context, and background, and barriers encountered in their work. A national sample (n = 122) of self-identified science coordinators completed a…

Purpose: This study presents the development and evaluation of a Constructively Aligned Teaching Sequence (CATS) for teaching the organismal biology of Senior High School. It tried to explore teaching-learning activities and assessment tasks that may be designed to address students' conceptions and teachers' difficulties in teaching organ systems.…

Chemical safety management is an iterative process where reviews of safety deficiencies (e.g., inspection notes) and failures (e.g., injuries) guide improvement efforts. The present work investigates safety in the school chemistry laboratory through two substudies. First, we interviewed 10 Swedish middle and high school chemistry teachers about…

This study examined how a contextually based authentic science experience affected the science identities of urban high school students who have been marginalized during their K-12 science education. We examined students' perceptions of the intervention as an authentic science experience, how the experience influenced their science identity, as…
