Why Do They Do What They Do? A Model That Describes and Connects the Drivers of Learning Assistant Facilitation Practices

Science Education, EarlyView.
ABSTRACT Learning assistants (LAs) help implement evidence‐based teaching in undergraduate active‐learning courses and support student learning through their facilitation. Here, we present a drivers‐of‐LA‐action model with empirical evidence that connects across the macro level of LA‐supported course design and the micro level of LA‐student ...

Laser‐Direct Printed 2D Material‐Based Heterostructure for the Fabrication of Electronic Devices

Small, EarlyView.
The Digital Laser‐Induced Forward Transfer (LIFT) approach is employed to pattern and stack 2D materials with micrometer‐scale precision. PdSe2 and MoSe2 are assembled into vertical p–n junctions, with graphene serving as a transparent electrode. The resulting laser‐transferred heterostructures exhibit high material quality and stable rectifying ...
