This study introduces the Extended Logistic Model for the Assessment of Change (ELMAC), a new method to quantify change over time. ELMAC provides parameters to assess the occurrence, trend, and consistency of change, with an application in learning processes.

Area of Science:

  • Statistics
  • Quantitative Psychology
  • Learning Sciences

Background:

  • Assessing change over time is crucial in various scientific disciplines.
  • Existing models may lack the granularity to precisely define the dynamics of change.
  • The need for a robust statistical framework to analyze temporal variations is evident.

Purpose of the Study:

  • To introduce and define a novel method for the assessment of change.
  • To propose a reinterpretation of the extended logistic model for change assessment.
  • To develop the Extended Logistic Model for the Assessment of Change (ELMAC).

Main Methods:

  • Reinterpretation of the extended logistic model.
  • Introduction of a time parameter to identify change occurrence and trends.

Related Experiment Videos

  • Calculation of a dispersion parameter to assess consistency of change.
  • Consideration of independence for both time and dispersion parameters.

    • Main Results:

    • The ELMAC model successfully defines a time parameter to identify change.
    • A dispersion parameter was calculated to measure the consistency of change.
    • The model accounts for the independence of these parameters.
    • Application in a learning process demonstrated expected parameter interpretation and model fit.

    Conclusions:

    • The ELMAC provides a comprehensive framework for assessing change.
    • The model is capable of identifying the occurrence, trend, and consistency of change.
    • ELMAC offers a valuable tool for analyzing change dynamics, particularly in learning contexts.
