Scaling up a learning technology strategy: Supporting student/faculty teams in learner‐centred design

Many post‐secondary institutions are experiencing the challenge of scaling up their learning technology initiatives without a matching increase in staff resources. This mismatch is particularly acute at the design stage of projects, where both domain knowledge and instructional design expertise are needed. To address this, we are developing structures and tools for a small cadre of instructional design experts to support a growing number of learning technology projects developed by student/faculty teams. One of these tools, the Learner‐Centred Design Idea Kit, is an interactive WWW‐based resource now in a fourth iteration of use in an undergraduate course, Designing Learning Activities with Interactive Multimedia. The course and the LCD Idea Kit which supports it are part of a larger institutional strategy to introduce technology‐enabled change in the learning process, working ‘bottom‐up’ with individual faculty and using the LCD Idea Kit to scale up the course across multiple university departments. In this paper, we describe the course and the Kit in detail and provide and overview of our current status and lessons learned

Measurement of the CKM angle γ using the B^± → D*h^± channels

A measurement of the CP-violating observables from B±→D∗K± and B±→D∗π± decays is presented, where D∗(D) is an admixture of D∗0 and D¯∗0 (D0 and D¯0) states and is reconstructed through the decay chains D∗→Dπ0/γ and D→K0Sπ+π−/K0SK+K−. The measurement is performed by analysing the signal yield variation across the D decay phase space and is independent of any amplitude model. The data sample used was collected by the LHCb experiment in proton-proton collisions and corresponds to a total integrated luminosity of 9 fb−1 at centre-of-mass energies of 7, 8 and 13 TeV. The CKM angle γ is determined to be (69+13−14)∘ using the measured CP-violating observables. The hadronic parameters rD∗K±B,rD∗π±B,δD∗K±B,δD∗π±B, which are the ratios and strong phase differences between favoured and suppressed B± decays, are also reported
