STEM ac tivities are examples o f co nstructivist approaches’ applications i n education a nd because of its nat ure STEM education is student-centered (B ransford, Brown & Cockin g, 20 00). However, in this example we would like to derive the EM algorithm and see if the EM algorithm would match with our intuition. •It seeks truth and proof. Then, create an anchor chart. •It requires creativity. So it is a function of y. You definitely want to put some thought ahead of time into what your expectations for your students are. Intuitively, the estimated θ should be the sample mean of the m observations θb= 1 m Pm i=1 Yi. We start with an example. For example, in science you learn ways to increase or reduce friction on a surface to make objects moving across that surface move faster or slower. Increasingly, the influence of technology and the availability of information will shape those ideas and skills, resting in large part on how well we address science, technology, engineering, and mathematics in our K–12 education. Students will go home excited about STEM! Solution: To start the EM algorithm, we ﬁrst need to specify the missing data and the complete data. When we talk about STEM skills, we’re talking about the individual skills needed to do science, mathematics, and engineering, and those needed to use technology effectively. 1. Conversely, if they believed it would be longer, and were given the same 800-millisecond interval, they produced an interval a bit longer than 800 milliseconds. In Why STEM is important STEM is exciting and beautiful on its own. In this section we will study a new object E[XjY] that is a random variable. STEM stands for science, technology, engineering, and mathematics and is a term used to group these disciplines, which proves relevant when discussing educational policies, curricula, career prospects, etc. Intel: One of the leaders in innovative computer technology, Intel, has demonstrated their commitment to STEM. •Look at Fibonacci Numbers or Fractals! As a Grade 11 student enrolled in STEM (Science, Technology, Engineering and Mathematics), I felt lucky to have found the strand that I’m really comfortable with. If we consider E[XjY = y], it is a number that depends on y. •You discover the (physical) world around you. Make it with your students, and make it big so you can hang it up and refer back to it through the year. Here is a sample. A.2 Conditional expectation as a Random Variable Conditional expectations such as E[XjY = 2] or E[XjY = 5] are numbers. STEM Skills for the Future The success of the nation as we move through the 21st century continues to depend on ideas and skills. •The fields are always changing, and interacting. For example, if animals believed the interval would be short, and were given an interval of 800 milliseconds, the interval they produced was a little shorter than 800 milliseconds. SUGGESTED ACADEMIC TRACK – SCIENCE, TECHNOLOGY, ENGINEERING AND MATHEMATICS (STEM) STRAND SCHEDULING OF SUBJECTS* STEM Grade 11 Grade 12 1st Semester 2nd Semester 1st Semester 2nd Semester S Oral Communication in Context Reading and Writing Skills 21st Century Literature from the Example: Roll a die until we get a 6. •It is MUCH easier to start in STEM and move into a field College students in STEM (science, technology, engineering, mathematics) disciplines are increasingly faced with highly competitive and demanding degree programs and are at risk of academic overconfidence. Introduce Expectations. As a prime example of a company completely centered around STEM, Intel represents one of many industries who’s prosperity, and therefore the prosperity of our country, relies on future generations’ interest in these fields.
