Experimental Designs

An experimental design is a systematic process that allows researchers to evaluate the relationship between dependent and independent variables. There are three widely used types of experimental design - pre-experimental design, true experimental design, and quasi-experimental design. In pre-experimental design, the researcher compares the data before and after some interventions or treatments. The true-experimental design has more than one purposefully created group, a commonly measured...
Crossover Experiments01:16

Crossover Experiments

Crossover experiments, also called the repeated-measurements design, is a study design in which all experimental units are exposed to all treatments in different periods. Crossover experiments are generally used in psychology, the pharmaceutical industry, agriculture, and medicine.
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.

Area of Science:

  • Educational Psychology
  • Engineering Education
  • Psychophysiology

Background:

  • Traditional methods for studying student emotions in classrooms (surveys, interviews) rely on subjectivity and lack real-time measurement.
  • Existing objective measures using physiological sensors are often conducted in artificial settings, detached from authentic learning experiences.
  • There's a need for research addressing multi-modal data collection challenges, including recruitment, validity, and data analysis in academic emotions research.

Purpose of the Study:

  • To present a novel experimental protocol for objectively measuring students' real-time emotional and physiological responses during authentic assessment situations.
  • To address limitations in current research by enabling the use of multi-modal data sources within ecologically valid classroom environments.
  • To provide a framework for future studies on academic emotions that incorporate objective, real-time physiological data.

Main Methods:

  • Development of an experimental protocol integrating physiological sensor measurements and salivary collection best-practices.
  • Implementation of the protocol within an authentic assessment setting to ensure ecological validity.
  • Consideration of factors such as sensor accuracy, participant movement, and experimental design for reliable data collection.

Main Results:

  • The protocol allows for the collection of objective, real-time physiological data during authentic student assessments.
  • It overcomes the limitations of subjective measures and artificial experimental setups common in prior research.
  • The methodology is designed to enhance the understanding of students' psychophysiological responses in real-world educational contexts.

Conclusions:

  • The proposed protocol offers a robust method for objectively studying students' real-time emotional experiences in educational settings.
  • This approach facilitates a deeper understanding of the interplay between emotions, assessments, and learning.
  • Further research can build upon this protocol to explore various aspects of academic emotions using multi-modal, objective data.
