Your Child Needs these Vital Skills - ALOHA Mind Math

Your Child Needs these Vital Skills Our fast-paced society demands advanced knowledge and skills. How can you build a foundation of success for your child to perform well in school, while they develop transferable life and work skills to live a successful life? The framework of ALOHA Mind Math’s educational enrichment programs are designed to prepare grade school and middle school students with the vital knowledge and skills necessary to excel in school, plus gain an advantage over their peers. Sixteen percent of hiring managers claim a lack of soft skills in applicants is the reason they have difficulties filling jobs, according to ManpowerGroup, the leader in innovative workforce solutions specializing in temporary and permanent recruitment, career management and Human Resources consulting.1bit.ly/1eJ4jHk (Photo credit: Wikipedia) The career of the next generation could be hinged on their management of specific employee behavior, which they first picked up in grade school. A portion of our proven learning programs include 5 vital skills. Creativity Collaboration Problem Solving Communication Critical Thinking Skills Many school districts do not teach these skills. But, ask a teacher the characteristics of a high-achieving student and their answer will likely include these. If you, ask a human resources director in charge of the hiring and selection process their ideal hire characteristics and their answer will include a variation of these, which employers call soft skills. Are these vital soft skills transferable to the workplace after students graduate? Our novel and holistic whole brain development program develops a strong academic foundation for school and life. “Creativity involves breaking out of established patterns in order to look at things in a different way.” Edward de Bono Within our ALOHA Mind Math curriculum we include memory, cognitive reasoning, intra-personal skills, motivation, goal setting, and interpersonal skills, involving communicating ideas, interpreting and responding to others views. A 2012 report by the National Research Council supports our mission and programs, “that young people who both apply and develop intertwined cognitive intra-personal and interpersonal competencies in the process of deeper learning are better prepared for adult success.”2 The five vital skills we teach in our proven educational enrichment programs help children stand out among their peers. Creativity and problem solving are the basis of discoveries, innovation, invention, and re-engineering. This is behind every great organization which trail blazes a new path. Creativity involves imagination, thinking beyond the possible. Almost every tangible product is a result of creative thinking. Needless to say the modern marvel inventions of electricity, robotic surgery, internet, anesthetics, and the telephone impact our lives. These great discoveries were either born out of frustration to solve a problem or came to fruition from ingenuity. Children are naturally curious and creative. Developing and enriching their creativity and problem solving skills will allow them to flourish throughout their education, in extracurricular activities, and later in life. Collaboration and critical thinking skills go hand-in-hand to work as team. These advanced skills are difficult for young children because their brain is still developing and they need to be taught to work together. Just a few of collaborative and critical thinking skill competencies necessary in the classroom and workplace include the following. Patience Respect Evaluate a disagreement Provide support for your ideas Critical reading Keeping an open mind to others ideas and opinions Analytical Ask relevant inquisitive questions Great leaders have excellent communication skills. In the classroom this means a child is able to get their message across clearly and succinctly. This often involves reading an assignment, writing a summary or analysis, then presenting the report. To communicate effectively they also must understand the other person’s point of view. It does not mean they agree with them, but they understand their opinion or their message. The advanced skills of conflict resolution are necessary in the classroom, out of the classroom, in social settings, workplace and at home. ALOHA Mind Math provides the source for what students must learn to outperform their peers and later become the candidates employers seek. Our curriculum teaches vital transferable 21st century competencies and knowledge. We see amazing things from students and it is exciting to see them outperform their peers in school. Students overcome their fear of failure or success, develop an inner strength to challenge themselves, and persevere in the face of adversity, to go beyond what they ever thought were possible. It has always been ALOHA Mind Math’s mission to enrich their reading, math, and language arts, plus teach them the crucial skills they need now which will carry them throughout college, career, and their entire life to lead happy and successful lives. Discover the genius in your child. 1.Manpower Group (2013) “Talent Shortage Survey” 2.National Research Council (2012) Education for life and work: developing transferable knowledge and skills in the 21st century.

Are you afraid of new technology

Introvert Whisperer / Are you afraid of new technology Are you afraid of new technology? Hi! Just when I thought I was past the need to learn some new technology for my business for a while, it seems that wasn’t in the cards.  I’ll tell you all about it below because it might be something you will want to take advantage of. I think the lesson in this is that you never stop learning and growing.  Things change around you daily and the best illustration of this is technology but its only one thing that changes.  Pretty much everything does. The deal is you have to be change-ready in life and work.  If you aren’t you get by-passed quickly.  Also, your life gets confusing and frustrating.  Imagine, not having or using the Internet?  Or not having a cell phone?  Or a car?  Life gets tough very fast. Obviously, there is some judgment that needs to take place to figure out whether or not learning something will enhance your life in any way.  But, staying open to change and having a willingness to change, is and will always be an asset for you. Do you know what your next career step is?  Many people don’t. I want to help you accelerate your career by connecting you with your Free Instant Access to my eBook on how to construct your Career SMART Goals â€" that will help you put together your actions and keep you accountable.  Get your copy now and start your action plan today:  CLICK HERE FOR YOUR FREE CAREER MAPPING GUIDE! Dorothy Tannahill-Moran Introvert Whisperer Here’s how I look at it:  You can learn something new and make the change that goes with it.  If you’ve given it a good shot and you don’t think it’s worthwhile, then stop.  Sounds a bit like quitting doesn’t it?  Maybe it is but I think you never know if something is going to work well for you until you try it long enough to make a truly informed decision.  I think there is a certain freedom in the idea that you can give yourself permission to try something and if you don’t like it or it’s not beneficial, then move on. Now you know and before you tried, you didn’t really know. So, here’s what I’m up to.  I’m going to start doing live videos on Facebook starting next week.  My plan is to do a couple of minutes of a career success tip once a week.  If all goes well, then I’m going to do a second live video with a tip and open QA for those who join in and want some answers to burning career questions.   Right now, I’m aiming for 4pm central.  I have to learn this first and give it a few tests before Monday but its technology â€" always filled with surprises.  To make this easy for you to check out, pop over to the Introvert Whisperer page and like it: Introvert Whisperer Facebook Page Wish me luck.

Z Score Table

Z Score Table Z-Score Table: In Statistics, we come across the word random variables very often. The term random variables is not like the variables we encounter in algebraic expressions. From a random experiment, the set of possible values obtained are known as the random variables. Random variables are the set of all the possible values and out of the set it can take any value randomly. For instance in an experiment of tossing a coin, there are 2 possibilities: getting heads or getting tails. Let us assume the value of 0 for heads and 1 for tails and have a random variable X. Then we see that the two random events are heads and tails. It is written as X = {0, 1}. Sample Space is the set of all the values of the random variable. These random variables can be discrete or continuous. The random variable in the normal equation is the normal random variable. The normal distribution function is given by the equation as shown below: Z-Score Definition: A z-score value is measurement in Statistics which indicates a given scores relationship to the mean. Out of several scores, the z-score indicates how many standard deviations a given particular score is from the mean. The z-score value is also known as the Standard score, z-values, and normal scores. Since the normal distribution is also known as the z distribution, hence we use the letter z for the score. Interpretation of the z-score: If the z-score is 0, then it implies that the score is the same as the mean. If the z-score is negative, then it implies that the score is lesser than the mean. If the z-score is positive, then it implies that the score is greater than the mean. If the z-score is 1, then it implies that the score is 1 standard deviation greater than the mean. If the z-score is -1, then it implies that the score is 1 standard deviation lesser than the mean. If the z-score is 2, then it implies that the score is 2 standard deviation greater than the mean. If the z-score is -2, then it implies that the score is 2 standard deviations lesser than the mean. Z-score formula: Given the mean and the standard deviation, we can calculate the z-score value from the formula shown below: Example: In an exam, a student receives a score of 88 when the mean of the class is 76 with a standard deviation of 10. How much is the z-score? Given the students score, x = 88 Mean, = 76 Standard deviation, = 10 From the z-score formula, we get the equation: z = (x )/ == z = (88 76)/ 10 z = 12/10 = 1.2 Therefore the z-score in this case = 1.2 With this z-score we can say that the student has scored above average (mean), with a distance of 1.2 from the average score. Mean: Mean is the average of the given scores. From a set of values, mean can be calculated by adding all the values and then dividing by the number of values in the set as shown in the figure below: Example: What is the mean of the values: 4, 7, 11, 10, 8? Given 5 values. Mean = Sum of the values/ Number of values So mean = (4+ 7+ 11+ 10+ 8)/ 5 = 40/5 = 8 Hence the mean of the given values is 8. Standard Deviation: The measure of finding how spread out or distributed the values are in a given set of values is the Standard Deviation. It is expressed using the Greek symbol (sigma). Standard Deviation can be easily calculated by finding the square root of the Variance. Normal Probability Distribution: Normal Probability Distribution, also known as the Bell Curve is a graph which depicts a standard normal distribution. The name Bell Curve is given because of its resemblance to a bell shape. Bell curves are extremely important and are very commonly used throughout the studies in Statistics. The two numbers that are necessary for plotting this Bell curve are the Mean and the Standard Deviation. The Bell curve (figure shown below) for a certain set of data always has the mean located at the center. This is the also the point where the curve reaches the highest point, known as the top of the bell. The Standard Deviation determines how much the given data set values are spread out. If the Standard deviation is larger, then the bell curve will be more spread out. A Bell curve is symmetric and hence when folded at the mean, we get 2 equal halves. As shown in the figures below, it is estimated that approximately 68% of all the given data lies within 1 standard deviation of the mean. And, about 95% is covered within 2 standard deviations of the mean, and about 99.7% is covered within 3 standard deviations of the mean. Negative Z-Score Table: The Negative Z-Score Table consists of all the negative z-scores. These negative z-scores are all to the left of the mean. Left of the mean is also considered as being below the mean. Positive Z-Score Table: The Positive Z-Score Table consists of all the positive z-scores which are to the right of the mean. These positive z-scores are to the right of the mean. They are also considered to be above the mean. Example: In the Science exam, the mean of the scores of the class is 80 with a standard deviation of 12. Jack scored 98 on the exam. What is the approximate percentage of students who scored lesser than Jacks score? Given the student Jacks score, x = 98 Mean, = 80 Standard deviation, = 12 From the z-score formula, we get the equation: z = (x )/ == z = (98 80)/ 12 z = 18/12 = 1.5 Therefore the z-score in this case = 1.5 Since the z-score is a positive number, we look at the Positive Z-Score table for the percent of students who scored within 1.5. As highlighted in the figure on the right, the value is 0.9332, which implies 93.32% of students scored lesser than Jack.
