What is educational trajectory?

6The concept of educational trajectories refers to how individuals proceed through different educational stages, how they combine them with other life spheres, how they cope with transitions and how they take decisions regarding their educational career.

What is the main trajectory of curriculum development?

Thus, the notion of a path, or trajectory, has always been central to curriculum development and study. In his seminal work, Simon stated that a “hypothetical learning trajectory” included “the learning goal, the learning activities, and the thinking and learning in which the students might engage” (1995, p. 133).

What is a math trajectory?

In dynamical systems, a trajectory is the set of points in state space that are the future states resulting from a given initial state. In a discrete dynamical system, a trajectory is a set of isolated points in state space. In a continuous dynamical system, a trajectory is a curve in state space.

Why is math an important topic in early childhood?

Math is an important part of learning for children in the early years because it provides vital life skills. They will help children problem solve, measure and develop their own spatial awareness, and teach them how to use and understand shapes.

What is the learning trajectory for counting?

Counting is the first step-by-step procedure that children learn that solves certain problems—determining how many elements are in a finite set. Children also learn to quickly tell how many there are in a collection if one is added or removed by counting up or down.

What is the counting trajectory?

Counting includes 1) the ability to say number words in correspondence with objects (enumerate objects), 2) understanding that the last number word said when counting refers to how many items have been counted (cardinality), and 3) using counting strategies to solve problems.

What are the three types of trajectories?

Types of trajectories include:trajectory of a projectile. lofted trajectory, a particular type of non-minimum energy ballistic trajectory.trajectory (fluid mechanics), the motion of a point in a moving fluid.in motion planning, the trajectory of a robotic motion.phase space trajectories of dynamical systems.

What is an example of a trajectory?

The definition of a trajectory is the curved path something takes as it moves through space. An example of trajectory is the path taken by a paper airplane as it flies through the air. The path of a body as it travels through space.

How do you do trajectory?

Use this trajectory calculator to find the flight path of a projectile....y = h + x * tan(α) - g * x² / (2 * V₀² * cos²(α))time of flight;maximum height;projectile range;horizontal projectile motion.

Why are the teaching and learning of mathematics are important at pre school level?

Math is important and it's important to help young children develop their mathematical thinking. A child's math knowledge at the start of kindergarten predicts later academic achievement better than early reading or attention skills. Math is part of children's everyday lives.

How important is where you start early mathematics knowledge and later school success?

The fact that early mathematics knowledge and skills are the most important predictors not only for later math achievement but also for achievement in other content areas and grade retention supports a greater emphasis on mathematics than is currently the case in many kindergarten classrooms.

Why is learning mathematics important?

Mathematics helps us understand the world and provides an effective way of building mental discipline. Math encourages logical reasoning, critical thinking, creative thinking, abstract or spatial thinking, problem-solving ability, and even effective communication skills.

Why are learning trajectories important?

Learning trajectories allow teachers to build the mathematics of children – the thinking of children as it develops naturally. So, we know that all the goals and activities are within the developmental capacities of children. We know that each level provides a natural developmental building block to the next level.

What are Learning Trajectories?

At the heart of the Learning and Teaching with Learning Trajectories [LT]2 website are mathematical Learning Trajectories. Children follow natural developmental progressions in learning. Curriculum research has revealed sequences of activities that are effective in guiding children through these levels of thinking. These developmental paths are the basis for learning trajectories.

What are the three parts of a learning trajectory?

These developmental paths are the basis for learning trajectories. Learning Trajectories have three parts - a learning goal , a developmental path along which children develop to reach that goal, and a set of activities matched to each of the levels of thinking in that path. Together, these help children develop to higher levels ...

How do developmental levels support teaching and learning?

How do these developmental levels support teaching and learning? The levels help teachers, as well as curriculum developers, assess, teach, and sequence activities. Through planned teaching and also encouraging informal, incidental mathematics, teachers help children learn at an appropriate and deep level.

What are the levels of attainment?

Most levels are levels of thinking. However, some are merely “levels of attainment” and indicate a child has gained knowledge. For example, children must learn to name or write more numerals, but knowing more numerals does not require deeper or more complex thinking.

What is subtrajectory in math?

A subtrajectory is a group of levels that are loosely coupled with a larger trajectory. While present within the development of the larger trajectory, the dependence of building iteratively from one level to the next may not be essential. Thus, subtrajectory levels may appear 'out of order' in terms of the child's age and development.

Why are teachers more effective in math?

Research shows that when teachers understand how children develop mathematics understanding , they are more effective in questioning, analyzing, and providing activities that further children’s development than teachers who are unaware of the development process. Consequently, children have a much richer and more successful math experience in the primary grades.

Why is knowing your why important?

This is why knowing your why is important. It is the force behind what you do. When you choose to continue to sleep instead of getting up and work on your goals, it is because you don’t have a strong purpose for your goals. When something becomes a must-achieve, you will do whatever it takes.

When you know your why and why, you can become unstoppable?

As what you have learned, when you know your why and your reason behind, you can become unstoppable. Never again fail to follow through your plans and goals. You can achieve what you want when you have a strong and powerful purpose for it. Remember, when there is a will, there is a way. Period.

Why do people fail to exercise?

Everyone knows that they need to exercise on a regular basis to maintain their health and to stay fit, but most people fail to do it consistently because their desire is not strong enough.

Why don't people have a strong why?

But one of the most common ones is that most people have been conditioned to want what others want. When they see that people are driving a better car, they want it.

How does writing things down help you?

According to this article from LifeHack.org, writing things down can change your life. When you put your thoughts on paper: 1 It clears your mind for higher-level thinking. 2 It helps you process your emotions. 3 It gives you a record of the past. 4 You gain a sense of achievement. 5 It helps you think big. 6 It makes you more committed.

Why don't you want to cross a plank?

In the first scenario, the plank is between the two buildings and you don’t want to cross it because your life is at risk. You can fall and die. But in the second scenario, with the same risk, you choose to walk across because you want to save your child. Your why has changed. “There is one quality which one must possess to win, ...

Why do we study projectile motion?

We study projectile motion because it is the simplest possible implementation of Newton’s laws. If we don’t understand what happens when the acceleration of a body is constant, then we’re going to have a very difficult time understanding what happens when it isn’t.

Why is projectile motion important?

The importance of projectile motion is defined for jet propulsion, rocket launching space exploration, missile launching and so also in paratrooping. Neil Armstrong and Buzz Aldrin would not have been able to walk on the moon and come back to earth if nobody studied projectile motion.

What is a projectile?

A projectile is any object that is given an initial velocity and then follows a path determined entirely by gravitational acceleration. Regardless of whether you're launching a balloon, a baseball, or an arrow, all projectiles follow a very predictable path, making them a great tool for studying kinematics.

How to make a projectile move?

You can try it out from where you're sitting. Pick up an object, and gently toss it up and away from you. It will rise as it flies away from you, reach a maximum height, and then start falling down to the floor. Toss a few more objects while you're at it. As long as you're not tossing pieces of paper or feathers, the projectile paths should be similar. We'll touch on this concept a bit later.

Why does the horizontal component of a projectile stay constant?

The horizontal component of the projectile's velocity stays constant because there is no horizontal acceleration. This is important: the force we applied to the projectile has nothing to do with the fact that its horizontal velocity doesn't change! The fact that it doesn't change is simply a consequence of inertia.

Who would not have been able to walk on the moon and come back to Earth if nobody studied projectile motion?

Neil Armstrong and Buzz Aldrin would not have been able to walk on the moon and come back to earth if nobody studied projectile motion.

Can you study the motion of a ball?

It helps tremendously that anybody can study the motion of a ball or a rock with some simple tools (a measuring tool and a stopwatch, along with a study partner.) This makes it possible to learn that some physical phenomena have simple formula that describe them, and, very importantly for future problem solving, that a wide range of problems can be understood through a few simple formulas.
