What Are Gravitational Waves? - Amber L. Stuver


In September 2015, scientists witnessed something never seen before: two black holes colliding. Both about 30 times as big as our Sun, they had been orbiting each other for millions of years. A fraction of a second before the crash, they sent a vibration across the universe at the speed of light that was picked up by the LIGO detector. So what are these ripples in space? Amber L. Stuver explains.

When to Hire a Tutor For Your Child


More parents today see tutoring as a natural add-on to their child's classroom learning. They realize even top schools can't focus individually on their child. And with private lessons in athletics and music so common, a private tutor for math, science or other subjects often makes good sense. Here are common times when hiring a tutor for your child is smart.

Your child is struggling in a subject or two.

If algebra class is 50 minutes but your son needs 60 minutes to learn the concept, he's going to fall behind in algebra and get discouraged. A math tutor will help the child who needs a little extra time. Tutors also re-teach past concepts and answer questions that kids are reluctant to ask in class. Tutors are expert in helping kids regain the motivation and confidence to succeed in math, science, writing, Spanish, or other classes.

Your child would benefit from homework and organization help.

Parents often seek a tutor for their child who isn't naturally organized. Some kids just need more supervision to get all their homework done to a high level. A 60-minute nightly tutoring session will nudge apathetic or scattered kids to work to their potential. Tutors will help kids manage due dates, get kids un-stuck by clarifying ideas or answering questions, and quality-check homework assignments.

Your child wants to achieve a goal or fulfill a hope.

Some families have a specific goal in mind when they start with a tutor. They want to raise a C to an A in calculus, or boost an SAT score 150 points. Other families have more abstract goals. They wish their child liked school more, or sympathize with a child who is trying hard but seeing only mediocre results. A tutor will listen to your hopes, and create a plan to help your child succeed.

You feel your child can improve study skills and test taking.

Many kids study the same way each year. But what works in 5th grade isn't enough in 7th grade. And the big leap from junior high to high school demands an upgrade in study skills. Kids with lagging study skills benefit immediately from a tutor who helps them increase homework time, pay attention to details, prepare for tests, and read more thoughtfully. A tutor can also ease test anxiety by teaching test-taking skills.

You hope to side-step a bad family dynamic, or provide stability.

By the teenage years, kids often will listen to any adult other than their parents. If that's the case, it's better for the child's grades (and family happiness) to bring in a tutor and remove the parent-child dynamic from the picture. Tutors understand teens and how to motivate them. And with younger children, parents can be too involved - doing all the homework themselves. A tutor gently returns responsibility to the child, while still providing consistency and support.

You have discovered your child likes to be tutored.

Parents often hire a tutor for a quick fix - usually to help their child bring up a grade in a tough class. But they'll continue with tutoring for years because their child really likes it. The one-on-one sessions help kids master even the hardest material, and signal that the family prioritizes their school success. Kids look forward to bringing home great test results, and to having undivided attention as they work on school assignments.

With today's school cutbacks, it's likely that more parents will try a private tutor and discover the benefits. Tutors are a smart way to ensure your children get the top education they need and deserve for later success in college and life.

Super 5: Back-to-School Power Moves to Start the Year Strong


Today we welcome Windy Lopez-Aflitto from Learning Heroes to the blog! Below, Windy shares "power moves" that parents can use to make back-to-school a success.

When it comes to getting your child off to a new school year, parents can be learning heroes. In addition to getting backpacks and school gear ready, this is a great time to get a clear sense of how to support learning at home throughout the year. Knowing your child’s interests, habits, and personality means that you have a head start and can help make learning fun and enjoyable throughout the year.

Yet, for parents to successfully support their child, they also need an accurate picture of their child’s achievement level.

Learning Heroes’ newly released national survey Parents 2017: Unleashing Their Power and Potential shows that nine in ten K-8 parents report their child as at or above grade level in both reading and math, two in three consider their child “above average,” and three in five are confident their child will be prepared for success in college. But national data tell a different story. For example, 2015 National Assessment of Education Progress (NAEP) data demonstrates that barely one-third of students perform at grade level.

To help parents get a full picture of how their child is progressing and start the school year strong, Learning Heroes created the Super 5: Back-to-School Power Moves, which includes the below 5 tips as well as free, easy-to-use resources and videos from National PTA, Scholastic, and many other trusted organizations.

Start Strong. As part of your back-to-school routine, find out how prepared your child is for his or her new grade. Pay attention to how easy or hard it is for your child to perform grade-level tasks, and review the annual state test results from last year. If you haven’t received the results yet, ask your child’s teacher. Compare this information to see where your child is doing well and where more support is needed.

Partner Up. You need your child’s teachers and they need you. At your first teacher meeting, bring your child’s state test results and ask what they mean for the year ahead. Find out what’s expected of your child this year and what you can do at home to help. Ask your child what he or she is most excited and
nervous about for the new
school year and why, and let the teacher know.

Make it fun! You are the expert on your child and can help make learning cool! Read together to discover topics that interest your child. Find math problems in everyday life and turn it into a game. Practice subtraction, measuring, and division when cooking together or while grocery shopping. These small learning moments add up to a lot!

Celebrate hard work. Our attitudes about learning–called “mindsets”–impact how our children learn, how they feel about making mistakes, and their self-confidence. Promote a “growth mindset” at home to help your child see that hard work is what leads to success. For example, focus on the specific effort and what your child is learning. This will help your child feel less nervous about new tasks or subjects.

Encourage life skills along the way. When it comes to your child’s potential and happiness, focus on the whole picture! Strengths like being able to communicate, problem-solve, show patience, and act independently will help your child in school and life. Talk openly with your child about how he or she is feeling and reacting to situations at school, on the playground, and at home.

The Science of Smog - Kim Preshoff


On July 26, 1943, Los Angeles was blanketed by a thick gas that stung people’s eyes and blocked out the Sun. Panicked residents believed their city had been attacked using chemical warfare. But the cloud wasn’t an act of war. It was smog. So what is this thick gray haze actually made of? And why does it affect some cities and not others? Kim Preshoff details the science behind smog.

Advantages of Getting a Math Tutor for Your Child


A math tutor is a teacher or expert who specifically teaches an individual about mathematical solutions and subjects. There are many different levels in tutoring. Some children in elementary and high school need tutorials in this subject because the lessons taught are becoming more and more complex. On the other hand, there are quite a number of students who do not fully understand what their teacher is teaching them in the classroom.

Due to the pace that some teachers teach, not all students are able to easily grasp the concepts that are taught in each mathematical lesson. While the teacher can entertain questions from the students about the aspects of the subject that may confuse them, there is a limited amount of time allotted for this particular topic every day.

Benefits

There are several benefits to getting a math tutor for a child, no matter the age or grade level. Elementary students and high school students benefit from tutorials because they can keep up with the pace that their teacher has set for the entire class. It is a good way to keep your child up-to-date with what is being taught in school. Another advantage in hiring a tutor is the confidence that the child develops when he or she understands what is being taught.

It can not only undermine a kid's confidence when he or she has trouble grasping the concept being taught, but it can also make him or her shy with the other kids who actually understood the lesson. Once the child loses the confusion that they have experienced initially, the awareness that they have finally understood it can be so heartwarming and enlightening to the child.

Another advantage that comes with hiring a math tutor is the one-on-one attention that the teacher can dedicate to the individual. Educators in schools make an effort to help their students understand the lessons they teach, but there is a lack of time and attention that they can dedicate to each student due to time constraints and the number of individuals in the class. Tutorial sessions are very advantageous because they are individualized and the specific needs of the student are addressed.

Another benefit that is gained from the presence of a math tutor is the specialization that the teacher has for the subject. In order to be successful, tutors need to see the curriculum that the child will be taught and they also need to see the homework and lessons that the school teacher has given the child for the day or for the week. Mathematics is a highly specialized subject that needs understanding and expertise. Professors or tutors on this subject are usually those who have particular knowledge of this subject while they were in school.

Hiring a math tutor has many different advantages, other than those listed above. Parents will be able to see the additional benefits after their child manifests positive results from the lessons received from these study aids.
