Velocity and Position by Graphical Method01:34

Velocity and Position by Graphical Method

Velocity and position can be calculated from the known function of acceleration as a function of time. The total area under the acceleration-time graph and the velocity-time graph gives the change in velocity and position, respectively. In the case of an airplane, its acceleration is tracked using the inertial navigation system. The pilot provides the input of the airplane's initial position and velocity before takeoff. The inertial navigation system then uses the acceleration data to calculate...
Acceleration Vectors01:30

Acceleration Vectors

In everyday conversation, accelerating means speeding up. Acceleration is a vector in the same direction as the change in velocity, Δv, therefore the greater the acceleration, the greater the change in velocity over a given time. Since velocity is a vector, it can change in magnitude, direction, or both. Thus acceleration is a change in speed or direction, or both. For example, if a runner traveling at 10 km/h due east slows to a stop, reverses direction, and continues their run at 10 km/h due...
Relative Motion Analysis - Velocity01:24

Relative Motion Analysis - Velocity

A stroke engine has a slider-crank mechanism that converts rotational motion from the crank into linear motion of the slider or vice versa. This mechanism consists of three main parts: the crank, the connecting rod, and the slider.
When an external force is exerted, it sets the crank into a rotational movement. This, in turn, instigates the motion of the connecting rod, leading to what is referred to as a general plane motion. This process involves two key points - point A on the connecting rod...
Relative Motion Analysis - Acceleration01:10

Relative Motion Analysis - Acceleration

A slider-crank mechanism converts rotational motion from the crank into linear motion of the slider or vice versa. This mechanism consists of three main parts: the crank, the connecting rod, and the slider. The movement of the slider-crank is an example of general plane motion as the fluctuating angle between the crank and the connecting rod. Consider a segment AB where point A is at the end of the slider and point B is on the diametrically opposite end to point A, on a crack. The variance in...

Area of Science:

  • Developmental Psychology
  • Linguistics
  • Educational Technology

Background:

  • Traditional lexical development tools offer limited insight into the learning process.
  • There is a need for dynamic assessment methods for early vocabulary acquisition.

Purpose of the Study:

  • To validate the FastMApp Android application as a tool for assessing referent selection in Spanish-speaking children (18-30 months).
  • To explore the utility of a fast mapping task within a mobile application for early language assessment.

Main Methods:

  • Sixty Spanish-speaking children (18-30 months) completed the FastMApp (22-trial noun task).
  • Caregivers provided parent-rated vocabulary inventory measures.
  • The task included 4- and 5-item trials with unknown objects.

Main Results:

  • Children demonstrated high task engagement.
  • Scores for known labels significantly exceeded those for unknown labels.
  • Performance was better on 4-item trials compared to 5-item trials.
  • A strong correlation was found between FastMApp scores and parent-rated vocabulary measures.

Conclusions:

  • The FastMApp application is a suitable tool for assessing early vocabulary acquisition in Spanish-speaking toddlers.
  • Mobile applications can provide valuable data on language learning processes.
