1. What is the primary advantage of the experimental method?
2. Read the scenario and answer the questions that follow it.
In a laboratory study of sleep deprivation, researchers employed a variety of techniques to keep volunteers awake for variable amounts of time. One group of participants was kept awake for 24 hours, and the other was kept awake for 48 hours. During periods of forced wakefulness, participants were required to engage verbal learning tasks such as memorizing the definitions of obscure English words. At the conclusion of the period of forced wakefulness, participants were allowed to sleep for as long as they wanted to. When participants awakened, researchers tested them on the learning tasks they completed during the periods of forced wakefulness. The researchers discovered that participants who were deprived of sleep for 48 hours recalled less than those who had been forced to remain awake for 24 hours.

What actions can you take to resolve this situation? What are the limitations of the requirements that must be considered? What should be the criteria that must be considered to evaluate and select the best alternative?
PLEASE BE SUPER SPECIFIC IN YOUR ANSWER. FOR SOME CONTEXT THIS IS A QUESTION FOR A PRODUCTION AND INVENTORY DESIGN AND ANALYSIS CLASS.

Implement synchronous send and receive of one word messages (also known as Ada-style rendezvous), using condition variables (don't use semaphores!). Implement the Communicator class with operations, void speak(int word) and int listen().
speak() atomically waits until listen() is called on the same Communicator object, and then transfers the word over to listen(). Once the transfer is made, both can return. Similarly, listen() waits until speak() is called, at which point the transfer is made, and both can return (listen() returns the word). Your solution should work even if there are multiple speakers and listeners for the same Communicator (note: this is equivalent to a zero-length bounded buffer; since the buffer has no room, the producer and consumer must interact directly, requiring that they wait for one another). Each communicator should only use exactly one lock. If you're using more than one lock, you're making things too complicated.

WRITE A SUMMARY IN 150 WORDS OR LESS FOR THE INFORMATION BELOW
Synchronous learning is the kind of learning that happens in real time. This means that you, your classmates, and your instructor interact in a specific virtual place, through a specific online medium, at a specific time. In other words, it’s not exactly anywhere, anyhow, anytime. Methods of synchronous online learning include video conferencing, teleconferencing, live chatting, and live-streaming lectures.
What are the advantages of synchronous learning
If you’re the kind of learner that likes active discussion, immediate feedback, and a personal familiarity that you can only get through real-time interaction, you’re probably a candidate for a synchronous learning experience. This is an especially important distinction if you’re just making the transition from the traditional classroom to an online setting. The personal contact that you get through live videoconferencing, lecture broadcasts or messenger chatting can make it a lot easier to make the transition. Essentially, you can have all the personal engagement of a classroom without getting all sketched out about germs during cold and flu season.
This experience comes with more than just engagement though. There’s a case to be made that synchronous online learning is simply a superior way to learn, that it allows for a more dynamic exploration of topics, ideas and concepts than is possible in a medium with time lag. Videoconferencing, for instance, makes it possible to ask questions and receive answers mid-lesson; to discourse and debate with classmates at a brisk and exciting pace; to collectively drive a conversation into unexpected new directions. There is a speed and immediacy to synchronous online learning that, at its best, evokes the same level of accountability and engagement as classroom attendance. If you thrive at a swift pace, surrounded by competing and complementary ideas, this is as close as you’ll come to the real thing.
With synchronous online learning, you’ll interact regularly and frequently with your professors. You’ll actually get to know your instructors. This is not just a good way to confirm your instructor’s credibility. It also provides regular opportunity for face-to-face discussion, individual guidance, and perhaps even the chance to establish a mentorship. If you’re the type of student that does your best work with the help of accessible and supportive instruction, you’re probably a synchronous learner.
What are the disadvantages of synchronous learning?
If you’ve chosen online learning because of your hectic and unpredictable work schedule, synchronous learning may present you with some challenges. The defining characteristic of this learning experience is its adherence to a set schedule. Lectures and class discussions will take place at established meeting times. If your job as a registered nurse keeps you on call at strange hours, or your parenting responsibilities render you fully occupied during the day time, or your hobby as an amateur storm-chaser means that you have to be ready to roll at a moment’s notice, you may have a hard time satisfying your course requirements. If flexibility is the number one reason that you’ve decided to go the online route, make sure you can manage your synchronous learning responsibility around your schedule.
The above concern is especially pressing if you’re a person on the go. If your work or life requires extensive travel, or at least the kind of mobility that forces you to complete coursework in weird places like coffee shops, airport terminals, and hotel lobbies, you’re probably always carrying a laptop and always searching for a wireless signal. That search could be pretty stressful if you’re desperately trying to log in for a videoconference, lecture, or heaven forbid, an exam. As a synchronous learner, technical difficulties like spotty internet, crashing hard drives, and dying batteries can become anything from an inconvenience to a disaster. Instead of logging in and sitting for your exam, you’re sweating profusely and sputtering profanities at your computer. Who has the time for that?

Using Extrinsic and Intrinsic Rewards to Motivate Student Achievement
Objectives
Introduction
The purpose of this exercise is to explore the use of rewards in motivating student achievement. There are two types of rewards—extrinsic and intrinsic—that can be used to fuel student motivation. Extrinsic motivation drives people’s behavior when they do things in order to attain a specific outcome. Extrinsic motivation is the payoff a person receives from others for performing a particular task. For students, these rewards include things like grades, getting better jobs, verbal recognition from peers and professors, academic scholarships, and admittance to honorary societies and associations. In contrast, intrinsic motivation is driven by positive feelings associated with doing well on a task or job. Intrinsic rewards are self-granted; the payoff comes from pleasing yourself.
