Toilets may seem harmless, after all - we use them multiple times a day - but don’t be fooled. These disarming devices have caused a surprising number of deaths throughout history. Let’s take a look at a few of them today.

A year ago, Ayat Husseini’s dreams of going away to college looked like they were evaporating. Her parents, an immigrant couple from Lebanon, had cultural objections and fears about her leaving her home in New York City. This fall, Education Week checked back on Ayat, now happily ensconced on a leafy green college campus in Pennsylvania.

Probability and statistics on Khan Academy: We dare you to go through a day in which you never consider or use probability. Did you check the weather forecast? Busted! Did you decide to go through the drive through lane vs walk in? Busted again! We are constantly creating hypotheses, making predictions, testing, and analyzing. Our lives are full of probabilities! Statistics is related to probability because much of the data we use when determining probable outcomes comes from our understanding of statistics. In these tutorials, we will cover a range of topics, some which include: independent events, dependent probability, combinatorics, hypothesis testing, descriptive statistics, random variables, probability distributions, regression, and inferential statistics. So buckle up and hop on for a wild ride. We bet you're going to be challenged AND love it!

About Khan Academy: Khan Academy is a nonprofit with a mission to provide a free, world-class education for anyone, anywhere. We believe learners of all ages should have unlimited access to free educational content they can master at their own pace. We use intelligent software, deep data analytics and intuitive user interfaces to help students and teachers around the world. Our resources cover preschool through early college education, including math, biology, chemistry, physics, economics, finance, history, grammar and more.

Grade 6th on Khan Academy: By the 6th grade, you're becoming a sophisticated mathemagician. You'll be able to add, subtract, multiply, and divide any non-negative numbers (including decimals and fractions) that any grumpy ogre throws at you. Mind-blowing ideas like exponents (you saw these briefly in the 5th grade), ratios, percents, negative numbers, and variable expressions will start being in your comfort zone. Most importantly, the algebraic side of mathematics is a whole new kind of fun! And if that is not enough, we are going to continue with our understanding of ideas like the coordinate plane (from 5th grade) and area while beginning to derive meaning from data! (Content was selected for this grade level based on a typical curriculum in the United States.)

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more.

When we tell a story, we must follow the right order - and to indicate this order of events, we can use sequence words. In this instructional video, Owen talks about these sequence words and gives an example of how to structure a story correctly, using them.

This video is part of a broader lesson plan that is aligned with CCSS.ELA-Literacy.CCRA.W.3: "Write narratives to develop real or imagined experiences or events using effective technique, well-chosen details and well-structured event sequences."

Now that we’ve talked a little bit about how sociology works, it’s time to start exploring some of the ideas of the discipline’s founders. First up: Émile Durkheim. We’ll explain the concept of social facts and how Durkheim framed sociology as a science. We’ll introduce the idea of common consciousness and how Durkheim believed it binds society together. We’ll also talk about Durkheim’s studies on suicide and how he applied his concepts to a specific social problem.

Multivariable Calculus on Khan Academy: Think calculus. Then think algebra II and working with two variables in a single equation. Now generalize and combine these two mathematical concepts, and you begin to see some of what Multivariable calculus entails, only now include multi dimensional thinking. Typical concepts or operations may include: limits and continuity, partial differentiation, multiple integration, scalar functions, and fundamental theorem of calculus in multiple dimensions.

Trigonometry on Khan Academy: Big, fancy word, right? Don't be fooled. Looking at the prefix, tri-, you could probably assume that trigonometry ("trig" as it's sometimes called) has something to do with triangles. You would be right! Trig is the study of the properties of triangles. Why is it important? It's used in measuring precise distances, particularly in industries like satellite systems and sciences like astronomy. It's not only space, however. Trig is present in architecture and music, too. Now you may wonder...how is knowing the measurement and properties of triangles relevant to music?? THAT is a great question. Maybe you'll learn the answer from us in these tutorials!

With a teacher-to-pupil ratio of 1:80 in most Nigerian schools, the quality of pupils’ attention and learning engagement continues to be on a nosedive trajectory with a negative impact on pupils’ motivation to learn, increasing drop-out rate, and the socio-economic risks of a poorly educated populace. According to a report by the United Nations Children's Fund, over 58.3% of pupils in Nigerian schools are not learning effectively (Vanguard News, 2018). Teachers are also becoming ineffective at inspiring pupils’ concentration via a classroom atmosphere that facilitates effective learning. The additional demands on teachers due to the higher pupil to teacher ratio also limits opportunities for teachers to offer personalised learning adapted to the children’s learning needs and providing the necessary psychological support.

This work explores how deep learning-powered cameras in a classroom can assist teachers to recognize and assess their pupils’ engagement levels and classroom behavioural patterns, with the goal of intervening when students need motivation and assistance. Specifically, the artificial intelligence algorithm assesses the students' facial expressions, classroom activities and their demonstrated levels of interest. We propose an integrated approach that includes neural network facial recognition and an Apriori-based mood extraction and human action detection to uniquely understand each pupil's learning needs. With a relatively low-cost camera that can quickly and precisely read pupils’ facial expression and class behaviour, many learning risk indicators such as emotional stress, personal frustrations, fatigue, academic disconnection and learning dysfunction can be automatically identified, allowing the teacher to intervene appropriately as needed.
