ABSTRACTNanotechnology and nanoscience have a strong potential to impact society and the commercial sector. It is critical to introduce this area to high school classrooms as a teaching tool. Here, we report the development of ferrofluid-based experimental modules in a team effort including a high school student and a high school teacher. The basic experimental modules were developed as follows: A) Electric motor-based patterning of magnetic nanoparticles and carbon nanotubes on a silicon wafer. Electromagnetically activated or ‘spiked’-ferrofluid was utilized here. B) Basic concepts of wettability, hydrophobicity, and oleophilicity were demonstrated by combining hydrophobic CNTs, water, and ferrofluids. C) Finally, the utility of ferrofluid-based environmental remediation was demonstrated for oil removal from oil-water mixture and organic dye separation from water-dye mixture. It is envisioned that the integration of the developed experimental modules into high school curriculum will motivate high school students to pursue degrees in science, engineering, and nanotechnology. Thus, this will assist in the development of future workforce in the area of nanotechnology and materials science.

Microbiology Research

A partnership between a community college biology professor and a local high school teacher was established to engage high school students in authentic microbiology research. High school students isolated actinomycetes from soil samples and tested them for their ability to produce antimicrobial chemicals. They also designed and carried out their own experiments with these isolates. Laboratory reports, written assignments, and quizzes were used to assess the scientific learning of the subject covered by the research project. The students' attitudes about science and scientific research were assessed using a standardized survey and written reflection questions. In completing this project, the students applied their knowledge of the scientific method and experimental design to address authentic research questions. They also learned several hands-on laboratory skills, including serial dilution, aseptic technique, isolation of pure cultures, Gram staining, microscopy, and antimicrobial testing. Student feedback was overwhelmingly positive – many expressed an increased interest in pursuing a career in science, and most felt that the project helped them gain confidence in their ability to do science. This project illustrates the importance of establishing partnerships between secondary schools and academic institutions to successfully introduce research to younger students.

Student motivation is always a central concern of the junior high school teacher, particularly in mathematics. In the present article we offer a sample unit of mathematics instruction suitable for junior high school students, with two purposes in mind: (1) to illustrate a current theory of learning and motivation, and (2) to offer a model for the construction of other such units. The unit is purposely built around division, since that topic is commonly disliked by both teachers and students.

During a summer's study under the auspices of the National Science Foundation,1 our History of Mathematics class encountered a most interesting Eulerian problem in infinite series. The problem is exemplary of an abundance of wonderfully rich and exciting historical materials. Acquiring a background in the history of mathematics is important to the high school teacher, for it provides an invaluable source of problem materials with which to capture the imagination and intellectual energies of students. High school mathematics curricula have often been criticized for not providing students with the opportunity to experience the excitement and the deep creative satisfaction of original se]f directed mathematical research. It is hoped that the development that fo1lows provides an example of a viable mathematics research project for secondary school students.

And Function

Graphing calculators are revolutionizing the learning and teaching of mathematics. Students can view and manipulate graphs of functions in a matter of seconds. Such features as “plot,” “graph,” “trace,” and “zoom” offer opportunities for users to develop an understanding of the terms variable and function. According to the Curriculum and Evaluation Standards for School Mathematics (NCTM 1989), these concepts are vital aspects of the middle school curriculum. According to the standards document, “[A]n ideal 5-8 mathematics curriculum would expand students' knowledge of numbers,… patterns and functions, and the fundamental concepts of algebra” (pp. 65-66). In addition, “[T]echnology, including calculators, computers, and videos, should be used when appropriate” (p. 67). It stand to reason that tools to aid in understanding such concepts as variable and function, specifically graphing calculators, should not be reserved for high school juniors and seniors. This article discusses the use of graphing calculators by students of middle school age in an enrichment program for academically able, but economically disadvantaged, students. The exercises described helped students develop an understanding about variable and function. Students were actively engaged in problem solving that involved hands-on, real-life activities.
