Today, the events {#blank#}1{#/blank#} in realistic-looking or-sounding video and audio recordings need never have happened. They can instead be {#blank#}2{#/blank#} automatically, by powerful computers and machine-learning software. The catch-all term for these computational productions is "deepfakes".

    The term first appeared on Reddit, a messaging board, as the username for an account which was producing {#blank#}3{#/blank#} videos. An entire community {#blank#}4{#/blank#} up around the creation of these videos, writing software tools that let anyone automatically {#blank#}5{#/blank#} one person's face onto the body of another. Reddit shut the community down, but the technology was out there. Soon it was being applied to political {#blank#}6{#/blank#} and actors.

    Tools for editing media {#blank#}7{#/blank#} have existed for decades—think Photoshop. The power and peril of deepfakes is that they make fakery cheaper than ever before. Before deepfakes, a powerful computer and a good chunk of a university degree were needed to produce a realistic fake video of someone. Now some photos and an Internet connection are all that is required.

    The consequences of cheap, widespread fakery are likely to be {#blank#}8{#/blank#}, albeit slow to unfold. Plenty worry about the possible impact that believable, fake footage of politicians might have on civil society—from a further loss of trust in media to the {#blank#}9{#/blank#} for electoral distortions. These technologies could also be deployed against softer targets: it might be used, for instance, to bully classmates by creating imagery of them in embarrassing situations. In a world that was already saturated with {#blank#}10{#/blank#} imagery, deepfakes make it plausible to push that even further.

Emphasizing social play in kindergarten improves academics

    Emphasizing social play and students helping one another in kindergarten improves academic outcomes, self-control and attention regulation, finds new UBC research. The study, published in the journal PLoS One, found this approach to kindergarten curriculum also {#blank#}1{#/blank#} children's joy in learning and teachers' enjoyment of teaching.

    "Before children have the ability to sit for long periods {#blank#}2{#/blank#} information, they need to be allowed to be {#blank#}3{#/blank#} and be encouraged to learn by doing," said Dr. Adele Diamond, the study's lead author. "Indeed, people of all ages learn better by doing than by being told."

    Through a controlled experiment, Diamond and her colleagues {#blank#}4{#/blank#} the effectiveness of a curriculum called Tools of the Mind (Tools). The curriculum was introduced to willing kindergarten teachers and 351 children with different backgrounds in 18 public schools.

    Tools was developed in 1993 by two American researchers. Its basic {#blank#}5{#/blank#} is that social-emotional development and improving self-control is as important as teaching academic skills and content. The Tools {#blank#}6{#/blank#} the role of social play in developing skills such as self-control, selective attention and planning. "Skills like self-control and selective attention are necessary for learning. They are often more strongly associated with school readiness (入学准备) than intelligence quotient (IQ)," said Diamond. "This experiment is the first to show {#blank#}7{#/blank#} of a curriculum emphasizing social play."

    Teachers reported more {#blank#}8{#/blank#} behavior and greater sense of community in Tools classes. Late in the school year, Tools teachers reported they still felt {#blank#}9{#/blank#} and excited about teaching, while teachers in the control group were exhausted. "I have enjoyed seeing the {#blank#}10{#/blank#} progress my students have made in writing and reading." said a Tools teacher in Vancouver. "I have also enjoyed seeing the students get so excited about coming to school and learning. They loved all the activities so much that many students didn't want to miss school, even if they were sick."
