A Review of High School Level Astronomy Student Research Projects over the last two decades

Since the early 1990s with the arrival of a variety of new technologies, the capacity for authentic astronomical research at the high school level has skyrocketed. This potential, however, has not realized the bright-eyed hopes and dreams of the early pioneers who expected to revolutionise science education through the use of telescopes and other astronomical instrumentation in the classroom. In this paper, a general history and analysis of these attempts is presented. We define what we classify as an Astronomy Research in the Classroom (ARiC) project and note the major dimensions on which these projects differ before describing the 22 major student research projects active since the early 1990s. This is followed by a discussion of the major issues identified that affected the success of these projects and provide suggestions for similar attempts in the future.Comment: Accepted for Publication in PASA. 26 page

Probing the Emission States of PSR J1107−5907

The emission from PSR J1107−5907 is erratic. Sometimes the radio pulse is undetectable, at other times the pulsed emission is weak, and for short durations the emission can be very bright. In order to improve our understanding of these state changes, we have identified archival data sets from the Parkes radio telescope in which the bright emission is present, and find that the emission never switches from the bright state to the weak state, but instead always transitions to the "off" state. Previous work had suggested the identification of the "off" state as an extreme manifestation of the weak state. However, the connection between the "off" and bright emission reported here suggests that the emission can be interpreted as undergoing only two emission states: a "bursting" state consisting of both bright pulses and nulls, and the weak emission state

K 1-6: an asymmetric planetary nebula with a binary central star

We present new imaging data and archival multiwavelength observations of the little studied emission nebula K 1-6 and its central star. Narrow-band images in H-alpha (+ [NII]) and [OIII] taken with the Faulkes Telescope North reveal a stratified, asymmetric, elliptical nebula surrounding a central star which has the colours of a late G- or early K-type subgiant or giant. GALEX ultraviolet images reveal a very hot subdwarf or white dwarf coincident in position with this star. The cooler, optically dominant star is strongly variable with a period of 21.312 +/- 0.008 days, and is possibly a high amplitude member of the RS CVn class, although an FK Com classification is also possible. Archival ROSAT data provide good evidence that the cool star has an active corona. We conclude that K 1-6 is most likely an old bona fide planetary nebula at a distance of ~1.0 kpc, interacting with the interstellar medium, and containing a binary or ternary central star. The observations and data analyses reported in this paper were conducted in conjunction with Year 11 high school students as part of an Australian Research Council Linkage Grant science education project, denoted Space To Grow, conducted jointly by professional astronomers, educational researchers, teachers, and high-school students.Comment: 13 pages, 5 figures, accepted by the Publications of the Astronomical Society of Australia (PASA

United We Stand, Divided We Fall: Historical Trajectory of Strategic Renewal Activities at Scandinavian Airlines System, 1946-2012

Although the second half of the twentieth century saw the rise and fall of ‘multi-flag companies’ in the civil aviation industry, our understanding of how some managed to buck the trend and achieve longevity remains limited. This paper advances business history and strategic management research by examining the strategic renewal activities of Scandinavian Airlines (formerly Scandinavian Airlines System) during the period 1946-2012. The study sheds light on the key roles of private and state owners, rivals as well as banks, in critical financial phases are discussed in terms of longevity in the company. The longevity of the business stems from the leaders’ ability to develop as anticipated and respond to change in their competitive arena in close interaction with the owners. Thus, incumbent firms that strategically renew themselves prior to or during market reform, such as deregulation, enhance their chances of developing the size of their networks and revenue streams. Our main contribution to business history and strategic management literatures is the development of context-specific stages, which shed light on the evolution of strategic renewal activities and shifts from older processes and routines towards customer service and efficiency

The Cosmology Distinction Course for gifted students

The Cosmology Distinction Course is an innovative subject introduced in 1994 for gifted students completing their Higher School Certificate (HSC) in New South Wales, Australia. It seeks to provide a challenging and stimulating, broadly based one year course that goes beyond the normal confines of traditional matriculation subjects. Provided free of charge it is taught via distance learning mode and includes a residential component

The Student as Scientist: Secondary Student Research Projects in Astronomy

Student research projects are becoming either integral or optional components of Science curricula in several countries. They provide a valuable opportunity for high school students to experience many of the joys and frustrations that make up the intellectual challenge of Science. Astronomy is one branch of Science that lends itself to student projects. Student Research Projects (SRPs) can be individual, group or collaborative between groups in other schools or countries and may involve professional mentors. Use of the Internet and remote access telescopes allow students to undertake challenging research and make worthwhile contributions to professional programs. This paper presents case studies of student projects in optical and radio astronomy from Australian and overseas schools and details both the benefits and problems faced in conducting such projects. Student responses to involvement in projects are discussed. Potential areas for future collaboration and development are highlighted together with the need for more research as to the most effective ways to implement projects and develop student skills

Engaging Gifted Science Students through Astronomy

Astronomy is a subject that poses many deep questions that intrigue students. It can effectively engage gifted and talented science students in their school years. Numerous international and Australian schemes utilize astronomy as a means of challenging and extending such students. Using Gagne's definition, gifted students have potential distinctly above average in one or more of the domains; intellectual, creative, social and physical. Talented students exhibit skills that are distinctly above average in an area of human performance. Such students may comprise about 10-15% of age peers in that field. They may be identified through a variety of means; by teacher, parent or self, sometimes via diagnostic tests, at others through participation in hobbies or other interests

The Internet as a Tool for Student Research and Communication - Australian Perspectives

The Internet is a valuable tool that allows students to access resources hitherto unobtainable in most high schools. The range, depth and power of resources related to astronomy provide school students with the tools to conduct educationally exciting and scientifically valid research projects. The use of the World Wide Web and Email allows students to communicate with each other and professionals. This is particularly useful for the delivery and support of distance learning and for collaborations. Examples of research and collaborative projects undertaken by students of Blue Mountains Grammar School, Australia, are given. The importance of a web-based bulletin board for student-student and student-teacher communication is demonstrated, using the NSW Cosmology Distinction Course as an example
