We investigated how students articulate uncertainty when they are engaged in structured scientific argumentation tasks where they generate, examine, and interpret data to determine the existence of exoplanets. In this study, 302 high school students completed 4 structured scientific arguments that followed a series of computer-model-based…

We describe a third-year undergraduate course that focuses on multiscale modeling and protein folding and has as its primary goal the encouragement of students to integrate thinking across and beyond disciplinary boundaries. The ability to perform innovative and successful research work in STEM (science, technology, engineering, and mathematics)…

Many students perceive science to be a difficult subject and are minimally engaged in learning it. This article describes a lesson that embedded an activity to engage students in learning science. It also identifies features of a science lesson that are likely to enhance students' engagement and learning of science and possibly reverse students'…

We present a simple, effective, and inexpensive spectrophotometer design that may be used in a stand-alone teaching module, and to enhance various unit operations experiments. The spectrophotometers described performed as well as a commercial option at estimating cell concentration in a bioreactor and tracking a first-order reaction. Such devices…

In this guided inquiry, students explore the complex hormonal regulation of the female reproductive cycle using inexpensive ovulation and pregnancy detection kits that are readily available over the counter. This hands-on activity engages students in the practice of doing science as highlighted by the "National Science Education Standards." The…

A series of qualitative analysis (QA) laboratory experiments utilizing a problem-based learning (PBL) module has been designed and implemented. The module guided students through the experiments under the guise of cleaning up a potentially contaminated water site as employees of an environmental chemistry laboratory. The main goal was the…

An experiment is described to introduce advanced undergraduate students to an exciting area of nanotechnology that incorporates nanoparticles onto carbon nanotubes to produce systems that have valuable technological applications. The synthesis of such material has been easily achieved through a simple three-step procedure. Students explore…

This paper provides a critical review of the changes to the role of practical work in the science curriculum in England over the last forty years. The science curriculum over this period appears to place an emphasis on an approach to practical enquiry that suggests school students can act like "real" scientists. This paper provides a…

Laboratory activities have long had a distinctive and central role in the science curriculum, and science educators have suggested that many benefits accrue from engaging students in science laboratory activities. Many research studies have been conducted to investigate the educational effectiveness of laboratory work in science education in…

With the emphasis placed on standardized testing, science education has been squeezed out. As a physics teacher, the author knows the importance of building children's interest in science early in their school career and of providing practice in basic science skills and inquiry. In order to make more time for science at her sons' elementary…

Creating inquiry activities is inherently difficult. Asking meaningful questions requires both background knowledge on the part of the students and complexity on the part of the phenomena. Yet numerous strategies can help teachers conduct inquiry activities. In this article, the authors share a taxonomy of teaching strategies used to create…

Citizen science programs are becoming increasingly popular among teachers, students, and families. The term "citizen scientist" has various definitions. It can refer to those who gather information for a particular science research study or to people who lobby for environmental protection for their communities. "Citizen science" has been called…

To enhance understanding of factors that might improve STEM career participation, we assessed students' self-perceptions of competency and interest in science/math, engagement in STEM activities outside of school, and knowledge of STEM career requirements. We show that the primary positive influencer directing students to a STEM career is high…

The purpose of this research was to examine and compare the effect of teaching the brightness of lamps, which is a topic for grade 11 physics lesson, on student achievement and attitude according to the 5E model belonging to the constructivist learning theory and the traditional teaching method. The research was conducted on 62 11th grade students…

Finding the time for developing or locating new class materials is one of the biggest barriers for instructors reforming their teaching approaches. Even instructors who have taken part in training workshops may feel overwhelmed by the task of transforming passive lecture content to engaging learning activities. Learning cycles have been…
