Times are definitely changing in the world of education. Today, as with all things twenty-first century, there are no limits to a student's education. This is absolutely exciting since so many 'schools without walls' have adopted various technologies during
the past few years to enable students excel academically. As an advanced tutor, it makes me dance in my shoes. Universities such as Harvard, Princeton, and MIT have posted several free virtual lectures for the average student on education applications via
android devices, iPads, iPhones, and iPods.
Today, I want to introduce some fantastic techniques to approach tutoring that will benefit the student who cannot meet physically with a tutor, or maybe a student who is in a town on one end of the United States while their tutor is at the opposite end
of the map. Yes, tutoring can now be employed with the use of fantastic applications such as Skype and Scribblar.
Skype: This is a tool by which a tutor can see his/her...
So far the Fall has been pretty good, a bit light as compared to the Spring, but most tutoring doesn't take place until after the first exam has passed or is just about to happen. Things are picking up and I am going to make good on my plan to have people
If you are interested in a lower hourly rate and are willing to travel to meet me, (within the city) let me know! I will tell you what borough I'll need you to meet me in that day and where exactly. Examples so far have been the Barnes & Noble on Union Square,
the Student Union in Queens College, and the Graduate Center (CUNY) right across from the ESB.
Looking forward to meeting new people and exploring more parts of the city this Fall.
It is often examples that make ideas understandable to students and current events can be a good source of examples. Case in point. Today in Wisconsin, the issue of the day is the outcome of the recall elections and problems with the exit polling. As a tutor,
the outcome isn’t interesting, but exit polling like all surveys is key to the usefulness of statistics! In fact, it gives a great opportunity to illustrate some of the basic (and non-mathematical) ideas and concepts of statistics — usually the ideas presented
at the beginning of most introduction-to-statistics courses.
Statistical inferences are grounded in some basic definitions and assumptions (in bold). A
population is a defined collection of individuals that we want to know some data about and a
sample is a group taken from the population that we are going to actually collect data from (Sullivan, 2010, p. 5; Triola, 2010, p. 4). If we wanted to know the actual data about a population, which is called a
My name is Kelsey, and I'm new to the world of tutoring. Although I am new to tutoring, I am excited to begin this new adventure and am proficient in Biology, Chemistry, Psychology, Genetics, Organic Chemistry, and ACT Science prep.
I am a recent graduate of Arizona State University where I earned a BS in Biological Sciences with a concentration in Genetics, Cells, and Developmental Biology. My future endeavors include returning to school for an MS in Genetic Counseling.
I look forward to working with anyone who needs a little extra help in any of my qualified areas!
I’m not good at this! I don’t like it! Why do I have to do this?
Were these questions my students were asking the other day? No, these were things I was saying at the gym yesterday. I hate to exercise. I’m definitely not good at it. I’m definitely not very highly motivated. Yet, I go there 4 times a week, because I know
it is good for me, and I don’t like how I feel when I don’t go.
Now, occasionally, a student will ask me these same questions and I admit, until I actually heard myself complain at the gym yesterday, I was sympathetic, but I didn’t get it.
I love math. I love science. I find it interesting and I do well in it. Why wouldn’t I want to learn more? Why wouldn’t I practice more? For every question I felt positive about in math/science, I could hear my negative response if I was thinking about that
answer in terms of the gym.
So, OK, I get it, math-science, not your thing. But I guarantee you that working consistently on something, even if you do not...

I'm new to this site and can't wait to help you. Got questions? I got answers! Whether you need some simple study skills and techniques or if you have very specific problems in a subject, I can help. Let me show you how all these subjects work together and
are not isolated disciplines that you're never going to use. I'll show you the relevance of each subject and how they're all integrated. Learning is so much fun when you understand why you need to know.
Genetics is a tough subject, but there's a few examples of everyday cats that everyone can recognize that will help remember some of the more esoteric vocabulary terms.
First lets think of a Siamese cat. Siamese cats are have gray-white bodies, and black feet, faces, ears, and the tips of their tails are also black. Why?
Second lets think of Calico cats. Calico cats are generally white-appearing cats with black and orange solid spots. Why?
If you don't recognize those cats immediately, its probably time for a Google image search, but lets move into the explanations:
Siamese cats have black at the "ends" of their extremities and bodies. What would create color in a cat but only at the periphery? And what is different about the ends of our own bodies? Ever notice, especially in cold weather, that your fingers and toes
are the first to feel numb? Blood flow into the extremities is more limited than throughout the main body cavity, and obviously...
Many students enter college with the intention of gaining acceptance to medical school. Many, however, lack adequate knowledge of the admissions process, which hampers their odds of success. In the 2007-2008 application season, for example, 42,231 individuals
applied to one or more of 126 allopathic programs. Ultimately, only 18,036 of these applicants had matriculated into a medical school. That is a success rate of only 42.7%!
Given the competitive nature of the application process, you'll need every advantage possible in order to maximize your own odds of acceptance. I've been through this difficult process myself, and having gained admission to UF College of Medicine, I'd like
to offer my advice to future applicants. In this series of blog posts, I will explain the basics of the process and point out where individuals are most likely to fail. The medical school application process is very competitive compared to what it once was
and has changed from even a decade...
Happy New Year! Are you ready for the new semester? No matter where you are in your education, first semester in college, or headed into that last one before graduation, being properly prepared will make all the difference!
1. Meet with an advisor and enroll as early as possible.
2. Get your books as soon as you can. Read through the table of contents and flip through he book to get an idea of what the course material will look like.
3. Know your schedule. Will you need to get up earlier then you are now? Now is a good time to start getting in a morning routine.
4. Get a planner (or use the calendar in your phone) to organize your schedule. This will help reduce cramming and over scheduling your time. Be sure to block out needed time for homework. I fill in all of my quizzes, exams, and reports due as soon as I
know of them.
5. Get plenty of sleep, water, and good food. Healthy snacks will help stabilize your energy levels and give you needed brain...
For most people, solving a problem or a question is not difficult if they have a model to follow and the correct data to plug into the model. Take one of the most basic functions, paying for something at a cash register. If the cashier tells you the Happy
Meal costs (with tax) $4.23, and you hand the cashier a $10.00 bill, I suspect that most cashiers will give and most people will expect their $5.77 in change. Oh, you can confuse people and make the problem more difficult (7 dimes, a nickel and two pennies,
rather than 3 quarters and two pennies), but these are just "tricks." This works, because for the vast majority of people, this is an "ordinary" occurrence something we've either done or witnessed hundreds of times, and we can intuitively extend our addition
and subtraction rules to a new problem.
Unfortunately, most classroom topics are taught like the math example above using clear, intuitive, and easily understood examples, but tested using...
I love to use analogies when I'm teaching in the classroom or when I'm tutoring. Analogies help students to better picture the concept I'm explaining and to retain it for years. An example of one of my analogies would be to compare no-dominance in genetics
to two very polite people trying to get through the door simultaneously so that each invites the other to enter first and politely refrains from pushing through the door. The result is that the two polite individuals enter hand in hand like no-dominant traits
(rw) that cause a blending effect, so a red and a white flower when crossed would form pink offspring. On the other hand, codominant traits fit the analogy of two pushy people trying to shove others out of the way as they enter the door first. This fight for
dominance forms offspring that have both the dominant traits (RW) so a red flower and a white flower would form offspring that are red with white splashes or white with red splashes.
