The primary objective of the activity presented here is to allow students to explore the frequency components of various simple signals, with the ultimate goal of teaching them how to remove unwanted noise from a voice signal. Analysis of the frequency components of a signal allows students to design filters that remove unwanted components of a…

The history of science is an important component to acquire for achieving scientific literacy. In this study, a collaborative activity was applied in which the students were presented with the historical context in which Robert Hooke lived and developed the first register of the microscopic world. Furthermore, the students explored the environment…

The oxidation of iron is an important reaction due to its high economic impact. In this laboratory exploration, the total order of this reaction was determined using commercially available handwarmer packets that rely on the iron-oxygen reaction to generate heat. The active ingredient in the handwarmer packet is iron, which interacts with…

The use of fossils as a tool in the classroom provide the medium in which students enthusiastically and directly engage in scientific exploration and thinking, enhancing their interest in future science curricula, and provide an avenue to develop scientific literacy. The National Research Council stated that students should have authentic…

Drawn from the cultural-historical theories of knowing and doing science, this article uses the concept of professional vision to explore what scientists and experienced teachers see and articulate as important aspects of climate science practices. The study takes an abductive reasoning approach to analyze scientists' videotaped lectures to…

In order to analyse whether or not the characteristic of scientific inquiry activities of textbooks in China satisfy the requirements of China's new curriculum reforms, content analysis method was adopted to analyze scientific inquiry activities in junior middle school physical textbooks (grade 8) of five editions authorized by the Chinese…

Cultural competencies and confidence in teaching diverse students are needed to close achievement gaps between mainstream and minority students in science. In this study, an online teacher education program, Virtual and Open Integration of Culture for Education (VOICE), was designed to help retain teacher candidates' science affinities and…

The concepts of "culturally relevant pedagogy" and "culturally responsive teaching" have been interpreted and enacted in various ways for over two decades. Informed by this research, the author shares a critical approach to teaching and learning using "sociotransformative constructivism" (sTc). This framework merges…

Speech and language development in children are crucial for ensuring effective skills in their long-term learning ability. A child's vocabulary size at the time of entry into kindergarten is an early indicator of their learning ability to read and potential long-term success in school. The preschool classroom is thus a promising venue for…

The underrepresentation of women and minorities in the science, technology, engineering, and mathematics (STEM) fields is a major concern for researchers, policymakers, and educators. Many causes of this issue have been identified over the years. However, effective methods for increasing minorities' and women's participation in STEM may still be…

Moonshot is the redesign of NASA's High School Aerospace Scholars (HAS), which traditionally engaged Texas high school juniors in a 16-week online course for credit and an intense week-long onsite experience working in teams with experts at NASA's Johnson Space Center (JSC). Due to the novel coronavirus (COVID-19), our challenge was to design,…

This study examines interactions of fourth graders and their parents during informal science activities to understand the parental influence on children's science interests, attitudes, and participation. Sixteen Latino/a parent-child dyads and 16 Non-Latino/a parent-child dyads, matched on socioeconomic status (SES), participated in this…

This research aims to examine: (1) how Physics teachers who participated in a STEM project, adopted and implemented a STEM activity in the context of a pandemic; (2) from the perspective of Physics teachers, what were the effects on students' learning of a STEM activity implemented in the context of the pandemic; and (3) what challenges had…

This manuscript elaborates the value of looking beyond the written and spoken word in science education research and practice at the early childhood level. We examine one plurilingual child's descriptions of a science activity to explore the "diversity of resources" that she used while expressing her understandings of a sound…

A conceptual framework for empirical research on the impact of NASA Space Science Education Consortium (NSSEC) activities is presented in this paper, along with a cross-referencing system between the NSF-based NSSEC evaluation framework and historical definitions of comparable psychometric constructs in the literature. A selected set of findings…
