The social controversy surrounding the teaching of evolution puts pressure on secondary biology teachers to deemphasize or omit evolution from their curriculum. In this growing pressure, professional development can offer support to biology teachers. In this study, we surveyed secondary biology teachers in Missouri and report the data from…

Year 11 chemistry students from three schools in the Sunshine Coast Region of Education Queensland carried out a choice of five experiments aligned with their school curriculum on campus at the University of the Sunshine Coast and in their own school classrooms. Significant improvements in science learning were observed in student post-test quiz…

Providing students with inquiry-oriented learning environments is a major concern in science education. Argumentation discourse can enhance the effectiveness of inquiry-oriented learning environments. This study seeks the trace of argumentation in Turkish Elementary and Secondary Science Curriculum developed by the Turkish Ministry of Education…

Offering expertise in the teaching of writing (Kim Jaxon) and the teaching of science (Leslie Atkins Elliott and Irene Salter), this book will help instructors create classrooms in which students use writing to learn and think scientifically. The authors provide concrete approaches for engaging students in practices that mirror the work that…

In this design case, we describe our work to design and develop a socio-scientific issue (SSI) based unit of instruction for use in high school biology. Our team includes university based science educators, an experienced classroom teacher, and a microbiologist. The unit focuses on antibiotic resistant bacteria as a context for student exploration…

A quite simple and inexpensive technique is described here to represent the approximate shapes of atomic orbitals and the molecular orbitals formed by them following the principles of the linear combination of atomic orbitals (LCAO) method. Molecular orbitals of a few simple molecules can also be pictorially represented. Instructors can employ the…

Glow sticks are a popular Halloween staple familiar to most of our students. The production of light via a chemical reaction is called "chemiluminescence," and glow sticks are often used as demonstrations and experiments in the chemistry classroom to study reaction rates as a function of temperature. A black light can be used to…

Evolutionary experiments are usually difficult to perform in the classroom because of the large sizes and long timescales of experiments testing evolutionary hypotheses. Computer applications give students a window to observe evolution in action, allowing them to gain comfort with the process of natural selection and facilitating inquiry…

This paper summarises research findings from a longitudinal national evaluation of science, technology, engineering and mathematics (STEM) "enrichment and enhancement activities". The activities included science practical lessons, supported by ambassador visits, trips to laboratories, STEM centres and higher education institutions. The…

Currently, science in England is distinctive at General Certificate of Secondary Education (GCSE) in comparison to most other subjects, in that there is a notable stratification of award routes. The most prestigious of these, "Triple Science" (the route for entry for three separate science GCSEs), is championed by English government and…

This research examined how a teacher's discussion of the strands of scientific proficiencies changed over the course of an inquiry cycle as students engaged in a complex, technology-enhanced inquiry learning environment called "PlantingScience" (PS). Our research is descriptive in nature and attempts to deconstruct the complexity of…

Since the first report of electroformed micrometer-sized liposomes in the 1980s, giant unilamellar vesicles (GUVs) have generated a lot of interest in the biophysical and biochemical communities. However, their penetration rate in high school or at the undergraduate level is still limited because of the requirement of specialized materials for…

Much research has identified organic chemistry as an area of difficulty for learners. There is also much literature pertaining to the factors that contribute to learners' difficulties. This paper explores the intersections of teachers' and learners' perceptions of teaching and learning organic chemistry respectively. Understanding these nuances…

This study examines how two kinds of authentic research experiences related to smoking behavior--genotyping human DNA (wet lab) and using a database to test hypotheses about factors that affect smoking behavior (dry lab)--influence students' perceptions and understanding of scientific research and related science concepts. The study used pre and…

This research study explored pre-service teachers' (PST) reflections of their student teaching experiences through AHA moments. Participants included 37 pre-service teachers enrolled in mathematics and science student teaching seminars. Qualitative methods were used to analyze PSTs' written and verbal responses to questions regarding AHA…
