Subclaims¶

q2 i? Students do a good job finding crossings in magnetic field data but have more difficulty with particle data. → Crumley 2007 q2 i? Some of the data sets students examine contain no magnetopause crossings, which disconcerts students but reflects the reality that research data sets often lack the phenomenon being sought. → Crumley 2007 (2)

Evidence¶

Crumley 2007¶

Crumley, Palczewski, and Kaster. (2007). Examining the Location of the Magnetopause in an Undergraduate Lab. https://arxiv.org/abs/0706.1985 doi:10.48550/arxiv.0706.1985

q2 · i? · the article prints no effect size for this finding · design · r2

Instructor-reported outcome from the spacecraft-data results section of the eleven-year lab use. The authors say this is expected because in most cases the ion data is not as clear as in their example figure. No effect size is printed.

"In general, the students do a good job of finding the crossings in the magnetic field data, but they have more difficulty with the particle data."

Crumley 2007 (2)¶

Crumley, Palczewski, and Kaster. (2007). Examining the Location of the Magnetopause in an Undergraduate Lab. https://arxiv.org/abs/0706.1985. doi:10.48550/arxiv.0706.1985

q2 · i? · the article prints no effect size for this finding · design · r2

Instructor-reported observation from the spacecraft-data results section: some assigned storm data sets contain no crossings. The authors frame this as valuable because in research there are often data sets that do not contain the phenomenon being searched for. No effect size is printed.

"One of the things that troubles some of the students is that some of the data sets they examine contain no magnetopause crossings. Finding no crossings disconcerts students since their expectation is that all data sets will have crossings."

• Students achieve reasonable agreement between their magnetopause-crossing findings and model predictions, gaining exposure to the tools and techniques of space physics — related
• Students' empirical fits of simulated magnetopause locations show good internal agreement, though student estimates and simulation-calculated locations often disagree beyond uncertainties — related
• Using a stair-step pattern of solar wind input conditions in the simulation portion of the lab led to much better student results than linearly varying conditions — related
