We present an alternative to the traditional classroom lecture on the topics of metabolic scaling, allometric relationships between metabolic rate (MR) and body size, and reasons for rejecting Rubner's surface "law," concepts that students have described as challenging, counterintuitive, and/or mathematical. In groups, students work with…

This study investigates the ability of future primary school teachers to design experiments when confronted with everyday life problems, particularly those involving complex phenomena or counterintuitive outcomes. Data were collected using a content analysis approach from the written assignments submitted during a Science Education university…

The results of an earlier four-year longitudinal research study on the development of experimental design skills led to the conclusion that 12-13 year old students probably need more help to design experiments than had been offered to them in that project. This paper reports the findings of the first year of a further four-year empirical research…

This study describes how nine university professors managed their teaching when a shift from lecturing to inquiry-based learning was mandated in a large enrollment course, linear algebra for math majors. We describe the tensions that emerged and how they were resolved, in part via the production of worksheets that were used in teaching. We…

Teaching race and ethnicity in various sociology courses, we found students in our classes can be very reluctant to approach the subject of race, discrimination, and racism. Moreover, during class discussion, they often have a hard time defining and analyzing these concepts. In this study, we examine how popular culture can be a useful tool to…

The purpose of this study was to investigate both the individual and relative effectiveness of two conceptual change interventions, gender and their interactions on preservice science teachers' conceptual understanding and their misconceptions in mechanical waves. The interventions are conceptual change texts enriched with concept cartoons (CCTCC)…

During the second industrial revolution (1870-1914), scientists moved away from trial-anderror methods to more systematically apply the principles of chemistry, physics, and biology (Mokyr 1998). The authors chose this period as the foundation of a project-based learning (PBL) unit integrated with the ninth-grade U.S. history curriculum (Thomas…

This article reports on techniques of teaching abstract algebra which were developed to achieve multiple student objectives: reasoning and communication skills, deep content knowledge, student engagement, independence, and pride. The approach developed included a complementary combination of inquiry-based learning, individual (not group) homework…

Although active learning methodologies have been implemented in geoscience classes successfully, no direct comparison between these different instructional techniques exists to date. For that reason, the purpose of this study was to compare the effectiveness in student learning of two active learning methods: peer instruction and lecture…

This educator guide is organized into seven chapters: (1) Overview; (2) The Design Challenge; (3) Connections to National Curriculum Standards; (4) Preparing to Teach; (5) Classroom Sessions; (6) Opportunities for Extension; and (7) Teacher Resources. Chapter 1 provides information about Environmental Control and Life Support Systems used on NASA…

National Aeronautics and Space Administration (NASA) Engineers at Marshall Space Flight Center, Dryden Flight Research Center, and their partners at other NASA centers and in private industry are currently developing X-33, a prototype to test technologies for the next generation of space transportation. This single-stage-to-orbit reusable launch…

This student employee handbook offers tips on planning, design process, and presentation of a student Lunar Nautics project. Each section includes mission, task, challenge, and guide questions. With the activities presented, students will learn to design a Lunar Lander, Lunar Miner, and Lunar Base; investigate the geography and geology of the moon…

This guide was prepared as a tool useful for informal education venues (4-H, Boys and Girls Clubs, Boy Scouts, Girl Scouts, etc.), science clubs and related programs, and can be adopted for formal education settings. An exciting and productive study in rocket science can be implemented using the selected activities for the above-mentioned…

National Aeronautics and Space Administration (NASA) Engineers at Marshall Space Flight Center, and their partners at other NASA centers and in private industry, are designing and beginning to develop the next generation of spacecraft to transport cargo, equipment, and human explorers to space. These vehicles--the Ares I and Ares V launch…

This research focused on students' learning of mathematical rules with reasoning. A small group of students (age 11-12 yrs) was observed closely by the first author as she taught them fraction rules. The area of focus was fractions and activities were designed pertaining to the four rules of fractions: addition, subtraction, multiplication, and…
