What can you do to increase interest in and student success with mathematics? Society for Industrial and Applied Mathematics, Philadelphia, (SIAM), surveyed more that 400 math teachers across the United States to gather their feedback on how they teach and learn mathematics.
Michelle Montgomery, SIAM’s project director for MathWorks Math Modeling(M3), said that “Students can be successful in math classes if they put in enough effort, attitude, and behavior.” As noted by Domyhomework123, using mathematical modeling in solving real open-ended problems is a great method for students to use their quantitative skills to get started. All the teachers who were interviewed were coaches of student teams that took part in M3 Challenge. The competition is online and there are no registration fees nor participation fees. Senior high school students and junior high school students spent a weekend working together on a real-world problem via mathematical modeling. The problem is available for download to students. They have just 14 hours to solve it. This adds pressure. The 13th annual contest was held in 2018.
WHAT DO TEACHERS RECOMMEND?
1. Build confidence. More than two-thirds of respondents (68%) identified lack confidence as one of the main problems that prevent their students from excelling in mathematics.
2. Encourage curiosity and asking questions. Sixty-six% agreed that the best advice they could offer students who want to excel in math was to not only pay attention, but to also ask for clarification if necessary.
3. Emphasize conceptual understanding over procedure. 75% of respondents (75%), said it was important to learn how to apply math concepts, not just memorize formulas.
4. Inspire students to learn math by creating authentic problems. Sixty three percent of participants stated that it was crucial for students to be motivated and take initiative in learning math. A majority (80%) of participants said that students are more involved in solving real-world mathematics problems than they were in math.
5. Encourage positive attitudes about math. Teachers should encourage parents to refrain from making negative comments regarding math, and to not say it’s difficult or irrelevant (74%). Instead, teachers should encourage children and guide them to find mentors in math if they have problems (71%).
It’s no surprise that teaching math modeling is an integral part of facilitation. The facilitation process allows students to model and solve real-world problems. Lauren Tabolinsky, a MathWorks academic programme manager, said that MathWorks sponsors M3 Challenge as it makes math relevant for both students and professionals.
Montgomery of SIAM believes modeling is integral to SIAM’s work. This includes motivation, identification of and control of variables that impact the issue (no feed data or approaches), gut checking of answers, and justifying proposed solutions. The results? It was a mixture of enthusiasm and an interest in solving a problem. The key ingredient is understanding that you can use your math skills to gain insight on the issues facing the world today.
One example: The 2018 M3 Challenge challenge titled “Better eaten than never: Reducing the waste food.” This problem was recognized by the Food and Agriculture Organization of the United Nations. An estimated one-third to three quarters of all food worldwide is wasted each year.
Mathematics was used by students to predict whether food insecurity would be met by food waste. Based on their personal characteristics and lifestyles, teams created a mathematical model to calculate a household’s annual food waste. They were presented with four types.
Finally, teams were asked for ideas on how to repurpose food leftovers. They used mathematical modeling to evaluate the benefits and costs of their options.
Students can choose how they approach these problems and how they will test them. They also have the option to decide what tools they will use for communicating their findings. Each member of the team has a role, there is plenty to do. You will be able to see how math modeling competitions can help students increase their mathematical skills, confidence, and passion when you compare the M3 Challenge modeling task with the guidance provided by the teacher coaches.
5 things to consider when choosing the best law school for you
Choosing to become a lawyer is not a decision taken lightly as it takes many years and a lot of hard work and determination. As such you want to make sure that you attend the best law school for your circumstances. With it being such an important decision, there are several things to consider when deciding which schools to apply for. Doing so will set your mind at rest that you end up in the right place.
If there is a specialty that particularly interests you in law, then the location of the law school you attend can help. This is because it is common to be hired locally to the school you attend and various industries congregate geographically. So, if you’re interested in political law and policy, Washington, D.C. is the ultimate location to look at law schools. Learn about where is best for your specific interests and look at which programs the local schools run.
Be realistic about which schools you are likely to get into early on. Upon studying how to get into Harvard Law school you will quickly realise that there is several years worth of dedicated work needed. As law is a postgraduate degree, the minimum for entry is a bachelors degree and passing the LSAT. For a topflight school you’ll need much more than this to impress the admissions department.
What Does Each Program Offer You?
While you need to prove your worth of being accepted when you apply to law school, it pays to check out what they offer you too. While you’ll learn a lot in the classroom, it takes hands on experience via externships, to really teach law practice. Therefore, a law school that offers plenty of practical opportunities is beneficial to your hiring potential after graduation.
Any course of study is hard work, especially once you get to postgraduate level, so it’s vital to have a good support network in place. Your school is a key part of that support structure, so you should research what support they offer to law students. This should cover mental health as there a many long hours involved, through to exam prep for taking the bar exam. Don’t forget to look at student organizations as well, as these provide excellent social opportunities which is vital to mental wellbeing.
Should you be successful in becoming a fully qualified lawyer, you will have to deal with a variety of people throughout your career. Learning in a diverse environment is essential to dealing with various people and scenarios at a later date. Being in such an environment also exposes you to different ways of thinking and approaching problems, which is beneficial to learning. Consider the diversity of not just the student body, but also the faculty, so that you get a good idea of the school’s attitude.
By taking these various factors into to consideration when choosing which law schools to apply to you will give yourself the best chance of a fulfilling and successful law career.
What are E-learning Authoring Tools?
E-learning authoring tools allow educators to spend time re-creating personalized e-learning systems that would work effectively in their own classrooms. Different types of e-learning authoring tools are available in the market. It can also be used for school ratings.These include:
PowerPoint-based tools: These are add-ins in PowerPoint that works as an e-learning tool. This offers an easy method for educators as they only need to convert PowerPoint presentations into e-learning modules. This will be a social media site for teachers.
Standalone authoring tools: These tools may require lots of time to master because users often need to begin with the preliminary training. Some standalone authoring tools may also need users to have programming skills to create their own personalized training content. It also helps teachers find education jobs.
Highly-specialized authoring tools: For educators looking to develop video content or incorporate software simulations, highly-specialized authoring tools are an ideal option.
Cloud-based authoring tools: Cloud-based authoring tools are easy to manage as users can start working immediately after logging in. Although each of these tools comes with its own functionalities, it gives educators the flexibility to create web-styled content.
Some major benefits of using e-learning authoring tools include:
Ability to repurpose existing content: E-learning authoring tools give educators the ability to repurpose all learning materials they currently have, as long as they’re in digital formats. For instance, instead of redesigning an interactive scenario, they can simply modify the existing one and upload it to the e-learning platform.I consider myself to be an expert when it comes to edtech.
Anyone can create engaging content: One of the biggest advantages of these tools is that anybody can use them to design immersive and engaging e-learning content. Some e-learning authoring tools are ideal for e-learning course developers without any prior design experience. You might want to use an app that helps students study. These tools give them the power to create unique content, interactive learning materials, and multimedia presentations for any subject matter.
Reduced course development time: Most e-learning authoring tools appear with a large selection of e-learning themes, templates, and objects that educators can use to build their e-learning courses quickly. These tools also make e-learning course development possible, especially for professionals who aren’t familiar with coding and graphic design.
Ability to publish the content on different platforms: Most authoring tools let users publish their content on different platforms, from mobile devices and tablets to laptops. Modern learners want information anywhere, anytime, and educators can make this possible via e-learning authoring tools.
Stress-free deployment: E-learning authoring tools allow educators to conveniently and quickly deliver their e-learning course content to all the members of their audience. One of my favorite things to teach was PEMDAS.They can upload the content to different e-learning websites and deploy it on any device or browser.

What You Need To Know About Ethiopian Coffee Beans
In this article, you are going to learn more about why Ethiopian coffee beans are so interesting to learn about, and why the country is worth the visit for coffee enthusiasts around the world.
Ethiopia might not be as big as Brazil and Colombia when it comes to the production of the international supply of coffee beans, but they are well-known to be one of the best countries if you want to get coffee. Coffee enthusiasts from all over the world visit this place in order to get its own unique strain of coffee beans, and simply because the coffee beans here are also superb in terms of its growth and overall quality.
After all, Ethiopia is considered as the country where coffee itself was found, and has its deep historical roots on how it got discovered. Some may think that coffee was found in
Colombia, but the country learned about coffee back in the 18th century only. But in the case of Ethiopia, coffee was discovered way back in the 9th century. Ever since then, Ethiopia became home to a wide variety of coffee beans, where some gained international fame and even became a signature coffee bean of other countries as these countries refined their ways of cultivating it.
The Renowned History Of Coffee Beans
It is not actually official if it’s true or not, but even neighboring countries claim the legend that Ethiopia was the place where coffee was first found. Believe it or not, it’s not some trader or researcher who stumbled upon this amazing fruit, but a goat farmer! Back in the 9th century, a goat farmer accidentally discovered the cherries of the coffee bean plant when he saw his goats consume it. He noticed his goats got too energetic unlike before when they never consumed the coffee beans. afr
As a result, he got curious if it also gives the same energy-granting properties to humans. That’s why he took some and shared it to the local monks in this place. Of course, they never know how to brew the fruit yet, so they consumed it first and realized that it can really grant them energy in a safe way. Over time, the method of consuming coffee beans eventually became the popular way that we all know about: turning it into an energizing and aromatic drink. As time passed by, word spread out about the properties of coffee and eventually gained worldwide fame that we all know about today.
Personally, this story about the discovery of coffee is really intriguing because who would expect that it was a farmer who discovered the wonders of the coffee beans by accident. History surely has a lot of unusual happenings that eventually laid an impact to a lot of people even to this day, and coffee seems to be one of them if this story is true.
The Importance Of Coffee In Ethiopia
The importance of Ethiopian coffee beans is not just all about the history that it had, and not just their strains that has a fruity flavor into it. The coffee industry of Ethiopia supplies 3% of the world’s overall coffee production. It might not be as huge as what Brazil can offer, but Ethiopia is still one of the holders of the industry’s foundation. Also, the U.S. happens to be one of the top buyers of Ethiopian coffee beans which are considered as the best African coffee beans.
In terms of the geographical importance of coffee in the country, take note that there are more than 1,500 square miles worth of coffee farms scattered throughout the country that’s dedicated for the cultivation and production of coffee beans. Just note the fact that the mountains where the farms are located have an altitude of up to 2,000 meters above the sea level. This environment is enough to grow the finest quality coffee beans. But of course, this also means that some of their coffee bean strains are considered as a luxury item due to its superb quality.

Types Of Ethiopian Coffee Beans
To get to know more about the strains that they grow here, take note of the following below:
- Longberry – These are large coffee beans that have a lot of body with a decent aroma and flavor. These are also called as Harrar coffee beans because of the region where it grows to.
- Mocha – Mocha is a well-known flavor around the world, and is often used in sweets because of its chocolate notes. The original Mocha coffee beans are highly-prized and can only be found in the Harrar region as well. Some also say that this the variant of the Harrar coffee bean that has a spicy note in it.
- Shortberry – The shortberry coffee beans are high-quality beans that has a very strong flavor that has a note of wine.
Ethiopia is a go-to if you are curious about the more exquisite, or even exotic, types of coffee to try out. This is worth marking on your map if you love to travel as a coffee enthusiast, or if you just want to travel and see the specialties that each country has in store for you.

How do they make Nitrous Oxide?
Before we get to how they make nitrous oxide, we first got to learn what is Nitrous Oxide? Nitrous oxide, commonly known as laughing gas, nitrous, N2O, or nos, or nangs is a chemical compound, an oxide of nitrogen with the formula N2O. At room temperature or the temperature that adapted to its surroundings, it is a colorless non-flammable gas, that gives off a slight metallic scent and taste. At elevated temperatures or above normal oral temperature, nitrous oxide is a powerful oxidizer similar to molecular oxygen. Nitrous oxide has significant medical uses, more so present in surgery and dentistry, for its anesthetic and pain numbing effects. Better known by the masses as “laughing gas”, it received this name due to the euphoric effects a person experiences after inhaling it, with this property that has led to its use as a anesthetic. You can readily buy laughing gas but only for culinary purposes.
It is on the World Health Organization’s List of Essential Medicines, the safest and most effective medicines needed in a health system. Though it became popular as an anesthetic, nitrous oxide has so many other uses. It increases internal combustion engine power, serves as an oxidizer in experiments including chemicals and rockets, and it also acts as a propellant for foods including cooking spray and whipped cream, and has multiple uses in medicine showing that it has its flexibility in uses as a chemical compound.
After learning what is Nitrous Oxide, How does someone produce said gas? The basic and safe method to make nitrous oxide at home or in a small lab was discovered by a chemist named Humphry Davy. Davy discovered that through heating ammonium nitrate, it decomposes into nitrous oxide and water vapor:
NH4NO3 (s) → 2 H2O (g) + N2O (g)
While simple, it’s crucial to gently adjust the heat of ammonium nitrate between 170 °C to 240 °C (338 °F to 464 °F). Exceeding the maximum temperature leads to rapid decomposition and the glass container to shatter due to reaching its breaking point. Use small amounts of ammonium nitrate then control the temperature with a thermometer just to be safe.
1. Place a small amount of ammonium nitrate in a test tube. Cap the test tube with a one-hole stopped. Insert plastic or glass tubing into the hole and run it into a hot water bath. The water needs to be hot because nitrous oxide dissolves in cold water, reducing the amount collected. Collect the bubbles in an inverted jar. This setup for collecting gases is called a pneumatic trough. It condenses water produced by the reaction and removes impurities, like smoke.
2. Once you’ve set up the equipment, slowly heat the ammonium nitrate. You can do this over a flame or burner. Apply heat so that it does not exceed the maximum temperature and so it produces gas bubbles at the rate of one to two bubbles per second.
3. Stop heating the ammonium nitrate before all of it has decomposed. This helps prevent overheating. Turn off the heat and disconnect the tubing from the collection jar so that water won’t flow up into it. Cover the container before turning it upright, so you won’t lose the gas. You can seal the container while it is inverted or simply cover it with a flat sheet of plastic or glass before turning it over. The gas in the container is nitrous oxide, plus smaller amounts of other nitrogen oxides, such as nitric oxide and nitrogen monoxide. Exposure to air oxidizes the nitric oxide to form nitrous oxide.
This procedure is commonly used for commercial preparation of nitrous oxide, with acid and base treatments to further purify the gas.
In 1772, another method for making nitrous oxide was discovered by Joseph Priestley and he became the first person to synthesize nitrous oxide. Priestly collected the gas produced by sprinkling nitric acid over iron filings. While an effective method, this method is better attempted in a lab by scientists because nitric acid should be used under a fume hood, with proper gear to avoid accidents. Another method to make nitrous oxide in the home or lab is to heat a mixture of sodium nitrate and ammonium sulfate. Again, collect the gas using a pneumatic trough. Heating this mixture is even safer than decomposing ammonium nitrate.
2 NaNO3 + (NH4)2SO4 → Na2SO4 + 2 N2O+ 4 H2O
The chemical reaction between urea, nitric acid, and sulfuric acid also produces nitrous oxide.
2 (NH2)2CO + 2 HNO3+ H2SO4 → 2 N2O + 2 CO2 + (NH4)2SO4 + 2H2O
Here are tips to prepare nitrous oxide safely:
– Never exceed the temperature when heating ammonium nitrate over 240 °C or 464 °F.
– Turn of the heating apparatus before the last bit of ammonium nitrate has decomposed.
– Use the highest purity ammonium nitrate available for the safest method. Pure ammonium nitrate is more stable than ammonium nitrate with impurities.
– Perform the project in a lab or in a well-ventilated area if at home. Overexposure can be fatal.
Due to the dangers difficulty involved in making nitrous oxide yourself you will most likely want to just buy nitrous oxide from an online seller and have it delivered to you.
