The first published account of the theorizing that was involved in the development of John M. Keller’s ARCS model is contained in a 1979 publication entitled Motivation and Instructional Design: A Theoretical Perspective. At that early stage, Keller explains his working definition, “motivation is generally defined as that which accounts for the arousal, direction, and sustenance of behavior” (Keller, 1979, p. 29). The emergence of Keller’s model was heavily influenced by a research into a variety of underlying motivational constructs. The theoretical alignment of the original ARCS model is covered more in-depth in the theoretical alignment section. The ARCS model has an official website. This textbook explores the ARCS model.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Immune checkpoints are an effective way that cancers evade the immune system, but they're not the only one. In the case of pancreatic ductal carcinoma, or PDAC, tumor fibrosis also plays an important role. To understand how fibrosis might translate to poor outcomes among patients with PDAC, researchers examined the ARF6-AMAP1 molecular pathway, which research suggests is activated during fibrosis. Findings revealed that AMAP1 correlated with elevated expression of PD-L1, a molecule that tumor cells present on their surface to elude attack by the immune system. AMAP1 was also linked to elevated fibrosis. Consistently, silencing AMAP1 in a mouse model of human PDAC reduced PD-L1 and fibrosis in their tumors. Suppressing the ARF6-AMAP1, therefore, could be one way to ensure that PDAC tumors can’t hide from immune defenses, offering the prospect of more effective immunotherapies for patients with pancreatic ductal carcinoma..."

Les ressources pédagogiques numériques créées dans les universités sont actuellement peu mutualisées. Les raisons que nous avançons sont leur manque de visibilité, la fragilité inhérente aux documents numériques, l absence historique de gestion de ce type d objets par les bibliothèques et les questions de propriété intellectuelle. Nous présentons le projet ARPEM, mis en place par Grenoble Universités pour répondre à cette problématique. Les premiers mois de fonctionnement nous permettent de présenter un rapport d étape et les évolutions prévisibles du projet.
