Creating Class Climates That Reduce Student Defensiveness

Creating Class Climates That Reduce Student Defensiveness

In collecting data for a new study on kindness in high school, this quotation from a student emerged as especially insightful. It illustrates the link between a student’s perception of the classroom climate and their subsequent behavior—building walls to feel safe. A high school student describes putting up walls to feel safe. Source: J.T. Binfet / used with permission Students who feel safe in a classroom engage differently than students who feel psychologically unsafe. They engage with content (e.g., lift their hand in class to ask questions or contribute), interact with peers, and allow teacher-student rapport to be established. Let’s encourage teachers to reflect on their investment in fostering class climate to reduce the “walls” that students put up. “Classrooms constitute the most important psychosocial environment of educational settings for young people in terms of the learning climate, cooperation, competition, student participation, and engagement, but also in terms of shared beliefs, emotions, habits, and peer pressure, also having an impact on school-age children’s well-being in both positive and negative ways (Eccles & Roeser, 2011).” —Rathman …

Most humans haven’t evolved to cope with the cold, yet we dominate northern climates – here’s why

Most humans haven’t evolved to cope with the cold, yet we dominate northern climates – here’s why

Humans are a tropical species. We have lived in warm climates for most of our evolutionary history, which might explain why so many of us spend winter huddled under a blanket, clutching a hot water bottle and dreaming of summer. Indeed all living apes are found in the tropics. The oldest known fossils from the human lineage (hominins) come from central and eastern Africa. The hominins who dispersed northwards into higher latitudes had to deal with, for the first time, freezing temperatures, shorter days that limited foraging time, snow that made hunting more difficult and icy wind chill that exacerbated heat loss from their bodies. Given our limited adaptation to the cold, why is it that our species has come to dominate not only our warm ancestral lands but every part of the globe? The answer lies in our ability to developed intricate cultural solutions to the challenges of life. Many humans dread the cold of winter.

Goodyear, Gatik say tire tech is key to bringing AVs to winter climates

Goodyear, Gatik say tire tech is key to bringing AVs to winter climates

Cars become an extension of the body when humans drive; we can feel the lack of grip in our car’s tires when driving over icy or wet roads. Autonomous vehicles don’t exactly have the same sensory abilities, which is one of the reasons why most AV testing and deployment happens in sunny climates. Gatik, a Canadian autonomous trucking company, thinks tire-sensing data might be the key to bringing self-driving tech to wintery roads. The company is working with Goodyear, the iconic tire company, to prove that intelligent tires can accurately estimate tire-road friction and provide real-time information back to Gatik’s automated driving system. “The tire is the only part of the vehicle that touches the ground, and this new level of data sophistication can communicate vital information to the vehicle, enhancing safety and performance,” said Chris Helsel, Goodyear’s senior vice president global operations and chief technology officer, in a statement. “This is another step to evolve the tire to not only deliver its core, traditional job but also be a nexus of new data and …
