Students over age 25 are an increasingly high percentage of higher education enrollments. These students, known as adult learners, enter college with life and work experiences as well as responsibilities, so they have different educational needs, expectations, and interests than traditional college students. The theory of adult learning that addresses the best ways to teach adult learners is called andragogy. While the construct of andragogy is subject to debate, the education field draws on...
Show moreStudents over age 25 are an increasingly high percentage of higher education enrollments. These students, known as adult learners, enter college with life and work experiences as well as responsibilities, so they have different educational needs, expectations, and interests than traditional college students. The theory of adult learning that addresses the best ways to teach adult learners is called andragogy. While the construct of andragogy is subject to debate, the education field draws on its findings todesign learning environments for adult learners. Academic libraries can also apply andragogy in their information literacy and instructional practices. This literature review examines articles in education and library science and summarizes evidence-basedinstructional strategies that address adult learning needs. The review also identifies the need for further studies on applying andragogy in library instruction.

We present a new distance estimation for the Milky Way dwarf spheroidal satellite Sculptor obtained from multi-epoch mid-infrared observations of RR Lyrae stars (RRLs). The 3.6 μm observations have been acquired with the Infrared Array Camera onboard the Spitzer Space Telescope as part of the SMHASH program. Mid-infrared light curves for 42 RRLs were obtained, from which we measured Sculptor’s distance modulus to be μ = 19.60 ± 0.02 (statistical) ± 0.04 (photometric) mag (with σsys = 0.09 mag...
Show moreWe present a new distance estimation for the Milky Way dwarf spheroidal satellite Sculptor obtained from multi-epoch mid-infrared observations of RR Lyrae stars (RRLs). The 3.6 μm observations have been acquired with the Infrared Array Camera onboard the Spitzer Space Telescope as part of the SMHASH program. Mid-infrared light curves for 42 RRLs were obtained, from which we measured Sculptor’s distance modulus to be μ = 19.60 ± 0.02 (statistical) ± 0.04 (photometric) mag (with σsys = 0.09 mag), using the 3.6 μm empirical period–luminosity relations derived from the Galactic globular clusterM4, orμ=19.57±0.02 (statistical) ± 0.04 (photometric) mag (with σsys = 0.11 mag) using empirical relations in the same passband recently derived from the Large Magellanic Cloud globular cluster Reticulum. Both these measurements are in good agreement with values presented in previous works with Sculptor RRLs in optical bands, and are also consistent with recent near-infrared RR Lyrae results. Best agreement with the literature is found for the lattermodulus which is equivalent to a distance of d = 82 ± 1 (statistical) ± 2 (photometric) kpc (with σsys = 4 kpc). Finally, using a subsample of RRLs with spectroscopic metallicities, we demonstrate that these distance estimates are not affected by metallicity effects.
