PRACTICE PRIVATE EDUCATION AS A HOME TEACHER

PRACTICE PRIVATE EDUCATION AS A HOME TEACHER

There are many reasons why you can give private lessons at home. First of all, a private teacher generally has the real desire to transmit his knowledge and to participate in the academic, professional or personal success of his pupil. Tutoring is also a great way to make ends meet and use your pedagogy to supplement your income.

Some also choose to give lessons to discover the teaching profession and know if they have the methodology necessary to make their students’ progress in the long term. You are an educator, passionate about your specialty (philosophy, mathematics or even the guitar) and you want to give lessons at home. So you have to think about choosing under what status you will teach. You could very well consider giving black lessons: no charges, no taxes, and this can indeed make your dream.

According to the Cons globe site, 80% of home tutoring courses are dispensed in this way. However, the risks involved quickly disillusioned: up to three years’ imprisonment and a fine of 45,000 euros. And don’t forget that in the event of a dispute, accident or damage, you have no recourse! Since you want to work calmly, you are wondering how you will be declared.

You have thought of the status of a particular teacher in self-employment, but you do not know if it is possible, or how to become one. Be a freelance teacher Are you tempted to? From the advantages of this self-employed status to the steps to get started, Super prof tells you everything! Self-employed: the ideal status for private lessons? The self-employed status was created in 2008. And that made many people want to start entrepreneurship! To date, more than a million French people have opted for this tax system according to the Legal start website.

Affiliated to the micro-enterprise, a natural person who decides to become a self-entrepreneur creates a sole proprietorship. He then benefits from a simplified social, tax and accounting system. The advantages of choosing a good tuition agency are numerous. Choosing to become a home teacher has many personal benefits. It is indeed very gratifying to participate in the upgrading of a student, to be for him a real educational adviser and to observe his improvement thanks to your lessons. Being a freelance teacher (or self-employed) has many other benefits: You are your own boss and can choose your students and the frequency of your lessons yourself. You set the price for your lesson hours yourself.

Your status can represent a significant advantage for parents because some works councils subsidize home lessons if they are given by an approved structure. You can complete your home teacher activity by giving lessons to students in small groups in an educational center and bill your services. You pay your contributions according to your turnover, if you don’t touch anything, you don’t pay anything.

You benefit from your pension rights and social protection via the SSI you can opt for the withholding tax from income tax. Also, be aware that it is quite possible for you to combine this status with a salaried activity if your schedule allows. However, if you are a professor of National Education, you must first apply to your academy before you can become an individual entrepreneur. You are then automatically affiliated with Bursar, SSI, and CIPAV (the pension fund for a liberal activity). To find students even more easily, we advise you to apply for accreditation. This will allow them to benefit from a tax reduction of up to 50%.

The students then have to place the amount paid to the teacher in the box “employee at home” of the tax return. Students must also keep the invoices in order to justify the recruitment of a home teacher. This is a significant argument for your students and their parents. Declare your income as a private tutor

When declaring your start of business, you must choose to declare your income every month or every quarter. There is no difference in choosing one formula over the other; it only depends on your organization and your preferences. Every month, or every quarter, you will, therefore, have to declare what you have earned through your private lessons at home.

The process is simplified and you can make your monthly or quarterly payment on the site of the auto-entrepreneur. After you have entered your turnover in the “declare and pay” section, the amount of your contributions is automatically calculated. You just have to pay with your credit card: that’s it! The social security contribution rate for the liberal professions in 2016 is 22.9% unless you have obtained ACCRE. The line to take into account is the following (Liberal Profession under the social regime of the self-employed).

Indeed, many people starting the activity of home teachers hesitate with the commercial profile. But, although you sell a service, a professor does not sell goods but a service. It is for this reason that the activity of the professor is registered in the liberal professions.

When it comes to mathematics, skipping any chapter is never advised. However, you can make sure your child studies regularly to avoid any issues. Some tips will make studies for exams easier, read ahead to know more.

How To Study From Maths NCERT Books?

Using NCERT books is very helpful because;

  • The language used in the book is very simple, meaning, your child can read it himself.
  • Reputed experts and teachers with vast experience have written the books.
  • NCERT books are a genuine source of information.
  • NCERT books are great for understanding the concepts easily.

Start Chapter-Wise

One of the best ways to make use of NCERT books is to study them chapter-wise. It means, your child studies the chapter in the textbook once and then do the exercises and then move on to the NCERT books. This will ensure your child is completely prepared for the exams. It is important to give equal time to both books to ensure your child is completely prepared. Solving all the problems present in the book means more practice and more knowledge.

Make A Study Schedule

A study schedule is very important when it comes to studying for the exam. Now, you can make separate study schedules for your child- one for the textbook and the other for the NCERT book. Or you can have one study schedule including both. Don’t overburden your child, but make sure you cover all the chapters from both books. When it comes to Mathematics, practice makes perfect.

Focus on Challenging Chapters

Your child needs to concentrate more on difficult topics, but without taking too much time. Maths is a subject where your child can score full marks. Therefore, make sure all chapters are covered.

Sample Question Papers

Solving sample papers is another great way to make sure your child is thorough. It can also help you understand their strengths and weaknesses, and since you will have ample time before the exams, you can work on any weaknesses.

Always Clear The Doubts

If your child has any doubts regarding a concept, make sure it gets cleared immediately. You can either talk to the teacher or hire an online tutor. It is also possible to understand the concept clearly with the help of the NCERT books.

Finally, remember, make sure your child remains calm and panic-free before and during the exam as it will help him remember everything more clearly. Also, try to make learning more fun, with quizzes, interactive games, and more as this will help your child learn better.

All You Need To Know About Molecular Spectroscopy

Spectroscopy involves the investigation and measurement of spectra produced due to matter interacting to give off electromagnetic radiation. In other words, it refers to the dispersion of light into component colours. It involves the interactions between molecules and electromagnetic radiation. Therefore that tells you that molecules oscillate from a lower energy level to a higher energy one and back repeatedly. In the process, the molecules absorb and radiate electromagnetic radiation. Here includes everything you need to learn about Molecular Spectroscopy.

Understand the meaning of a Molecule

A molecule is a group of positively charged atoms surrounded by a considerable number of negatively charged electrons. That explains molecular stability since there is a balance between the attractive and repulsive forces of the negatively charged electrons and positively charged nuclei. Moreover, a molecule is also characterized by the resulting energy that emerges from these interacting forces.

Types of Molecular Spectroscopy

The electromagnetic spectrum of a series of wavelengths is produced whenever a matter is exposed to any electromagnetic radiation. As a result, the Molecules will absorb a certain amount of wavelengths to the vibrational, higher electronic, and rotational energy levels. Therefore, the series of wavelengths a given molecule absorbs gives off a distinct molecular spectrum that lies in the specific region of the electromagnetic spectrum. Here are three types of molecular spectra you should know:

  • Pure Rotational Spectra

Pure rotational spectra occur when a molecule absorbs the least amount of energy that compels it to transit from one rotational level to the next but within the same vibrational level. It is possible to observe rotational spectra using the spectral region of Far Infrared and Microwaves. Moreover, the energies in these types of spectral regions are very small. That’s why they are referred to as all rotational spectra, the microwave spectra.

  • Vibrational Rotational Spectra

Vibrational, rotational spectra occurs when a molecule absorbs sufficient energy that causes the molecule to move from one vibrational level to the next within the same electronic level. However, in this case, both vibrational and rotational transition takes place. That is how you end up with vibrational, rotational spectra. With vibrational spectra, it is easy to observe the spectra in the Near-Infrared Spectral region. That’s called vibrational, rotational spectra, the Infrared spectra.

  • Electronic Band Spectra

Lastly, electronic band spectra happen when the radiation’s exciting energy is large enough to aid the successful transition from one electronic level to the next. Both rotational and vibrational level changes accompany this transition. Additionally, a set of closely spaced lines appear for each vibrational transition. These closely spaced lines are known as bands Because the corresponding rotational level changes.

Molecular Spectroscopy primarily involves the excitation of atoms and molecules using photons. They are excited by either resonant vibrations or electronic transitions based on the induced quantum mechanical changes. While vibrational transitions correspond to changes made within the molecular vibrational states, they typically appear in the infrared region. On the other hand, Electronic transitions specifically correspond to changes in the electronic state of the molecules. Moreover, it often appears in the UV-visible region.

Difference between an Algorithm and a Model in Machine Learning

If you are at a crossroads, wondering which data science certification to take for a highly relevant career upgrade, opt for a Machine Learning course at a reputed institute. It teaches you all the essentials of big data analytics and steers your career path to a more focused data scientist job role as a machine learning engineer. 

Before registering for the course, you may like to clear some concepts about machine learning algorithms and models. So here we are, discussing what is an algorithm and a model? What is the difference between the two?

What is Machine Learning

IBM lays down the definition of machine learning: “Machine learning is a branch of artificial intelligence (AI) and computer science which focuses on the use of data and algorithms to imitate the way that humans learn, gradually improving its accuracy.” It provides systems with the ability to automatically and iteratively learn and improve from experience. Machine learning is also an important element of data science, where algorithms train to make classifications or predictions, to uncover insights from massive quantities of data.

What is an Algorithm in Machine Learning

Some definitions of machine learning encapsulate the “algorithm” component of machine learning.

A McKinsey & Co. Insight states that “Machine learning is based on algorithms that can learn from data without relying on rules-based programming.” A University of Washington paper mentions how “Machine learning algorithms figure out how to perform important tasks by generalizing from examples.”

So what is an “algorithm” in machine learning? A machine learning algorithm is a program that provides systems the ability to learn on their own and improve from experience without being explicitly programmed. Machines adjust themselves to perform better as they are exposed to more data. 

What is a Machine Learning Model

A machine learning model is a file that has been trained to recognize certain types of patterns. A set of data is used and provided with an algorithm to reason and learn from the data, and this is called training the model. Once the model is trained with the given set of training data, it can be used to reason with unseen data and make predictions about that data. For example, if you want to build an application that recognizes a user’s emotions based on facial expressions. The model can be trained by providing it with images of faces tagged with a certain emotion and then used in an application that can then recognize any user’s emotion. 

A machine learning model is thus a condensed representation of what a machine learning system has learned.  It is similar to a mathematical function that takes a request as input data, makes a prediction on that input data, and then serves a response. 

The final set of trainable parameters of a model depends on the type of model. All machine learning models are categorized as either supervised or unsupervised. Where the model is a supervised model, it is further sub-categorized as either a regression or classification model. 

Difference between a Machine Learning Algorithm and a Machine Learning Model

An “algorithm” creates a machine learning “model.” A “model” is the output of a machine learning algorithm. The model represents what is learned by the algorithm. The Machine Learning model is “the “thing” that is saved after running an algorithm on training data and represents the rules, numbers, and any other algorithm-specific data structures required to make predictions.”

Examples

Examples of machine learning algorithms are linear regression, decision trees, convolutional neural networks, and reinforced learning. Some examples of machine learning models are Regression Models, Clustering Models, and Dimensionality Reduction Models.

Data set

Machine learning algorithms are executed in the code and run on data. Machine learning models are the output of the algorithms and consist of the model data and a prediction algorithm.

When you train an algorithm with known data, it becomes a model. 

Thus, Model = Training (of an Algorithm + Data)

Mathematical equation

Every algorithm has a mathematical underpinning, which, when executed in a machine, forms a machine learning algorithm. A model is an equation structured by discovering the parameters in the equation of the algorithm. The model specifies which family of functions the learning algorithm can choose from when varying the parameters to reduce the training objective. (Deep learning book, Goodfellow et al., 2016).

Algorithms are methods undertaken to get a task done or solve a problem, while Models are well-defined computations that are a product of an algorithm.

An algorithm takes some value as input and produces some value as output and is thus a sequence of steps with flow and loops, etc., transforming input to output.

Approach

An algorithm is an approach you take to solve a problem. The model is what you get when you run the algorithm on the training data and what you further use to make predictions on new data. A new model may be generated using the same algorithm but with different data, and a new model can be generated from the same data using a different algorithm.

Training data vs. new data

An algorithm is implemented in a programming language. An algorithm takes an input set of data and outputs an equation which is a model. Model is the output of the machine learning algorithm.

An algorithm can be used on different sets of training data. A model is then used as the deployment vehicle, which can take any unseen data in the future and produce an output prediction. That model has both data and a procedure for how to use the training data to make a prediction on new data, almost like a prediction algorithm.

Storing the entire dataset

Models are always triggered by the algorithm but not always dependent on the data. Based on the purpose that your model serves, some models like the k-nearest neighbors store the entire dataset, which acts as the prediction algorithm. 

Interrelationship

The algorithm behind the model matters most, as it is important to know which algorithm to apply to your model to yield the best predictions and right results. If the algorithm used is right, you will likely get a good model that works well on new data sets. However, a robust algorithm does not always yield a good model, as a machine learning model strategy depends on various factors other than the algorithm.

Ultimately, an algorithm is a few lines of code that you implement after much deliberation, while a perfectly working model is dependent on many other factors other than the algorithm or the training data.

Conclusion

Ultimately, a machine learning engineer works with big data to execute algorithms and build models for predictions. And a good way to kick-start a career in machine learning is to take a certification.
