The Role of Using Formative Assessments in Problem-based Learning: A Health Sciences Education Perspective

Practitioners in the field of pharmacy are often confronted with ill-structured problems. Specifically, pharmacists are tasked with making patient-specific recommendations that are both safe and effective, which requires combining knowledge from the biomedical, behavioral, and pharmaceutical sciences. Given the dynamic nature of pharmacy as a profession, the field has begun to explore learning strategies that go beyond mere content coverage to strategies that better support higher-order learning outcomes. One of these approaches is problem-based learning (PBL). While studies have focused on how to support PBL to improve learning outcomes, the role of assessment is often overlooked. Further exploration is thus needed since assessment plays a pivotal role in teaching and learning. This Voices paper will explore this idea within a larger context; we will also share the experience of how a subject matter expert (SME) worked with a team of instructional designers (IDs) to revise an existing course to more explicitly employ PBL and thus adopt an inquiry-based mindset needed for complex clinical decision making. Given the inherent challenges of assessment in PBL, further discussion will be focused on how to (a) design ill-structured problems, (b) align assessments to the PBL curriculum, and (c) how to hold students accountable in cases where a traditional grade is not attached

The planar thermal Hall conductivity in the Kitaev magnet {\alpha}-RuCl3

We report detailed measurements of the Onsager-like planar thermal Hall conductivity $\kappa_{xy}$ in $\alpha$-RuCl$_3$, a spin-liquid candidate of topical interest. With the thermal current ${\bf J}_{\rm Q}$ and magnetic field $\bf B\parallel a$ (zigzag axis), the observed $\kappa_{xy}/T$ varies strongly with temperature $T$ (1-10 K). The results are well-described by bosonic edge excitations which evolve to topological magnons at large $B$. Fits to $\kappa_{xy}/T$ yield a Chern number $\sim 1$ and a band energy $\omega_1\sim$1 meV, in agreement with sharp modes seen in electron spin-resonance experiments. The bosonic character is incompatible with half-quantization of $\kappa_{xy}/T$.Comment: 7 pages, 3 figure

Characterizing the Dust Coma of Comet C/2012 S1 (ISON) at 4.15 AU from the Sun

We report results from broadband visible images of comet C/2012 S1 (ISON) obtained with the Hubble Space Telescope Wide Field Camera 3 on 2013 April 10. C/ISON's coma brightness follows a 1/{\rho} (where {\rho} is the projected distance from the nucleus) profile out to 5000 km, consistent with a constant speed dust outflow model. The turnaround distance in the sunward direction suggests that the dust coma is composed of sub-micron-sized particles emitted at speeds of tens of meters s$^{-1}$. A({\theta})f{\rho}, which is commonly used to characterize the dust production rate, was 1340 and 1240 cm in the F606W and F438W filters, respectively, in apertures <1.6" in radius. The dust colors are slightly redder than solar, with a slope of 5.0$\pm$0.2% per 100 nm, increasing to >10% per 100 nm 10,000 km down the tail. The colors are similar to those of comet C/1995 O1 (Hale-Bopp) and other long-period comets, but somewhat bluer than typical values for short-period comets. The spatial color variations are also reminiscent of C/Hale-Bopp. A sunward jet is visible in enhanced images, curving to the north and then tailward in the outer coma. The 1.6"-long jet is centered at a position angle of 291$^\circ$, with an opening angle of about 45$^\circ$. The jet morphology remains unchanged over 19 hours of our observations, suggesting that it is near the rotational pole of the nucleus, and implying that the pole points to within 30 deg of (RA, Dec) = (330$^\circ$, 0$^\circ$). This pole orientation indicates a high obliquity of 50$^\circ$-80$^\circ$
