Area of Science:

  • Veterinary Education
  • Physiology Software

Background:

  • Acid-base physiology presents a significant learning challenge for veterinary students.
  • Traditional teaching methods may not adequately address the complexities of this subject.

Purpose of the Study:

  • To evaluate the effectiveness of the Acid/Base Primer software in improving veterinary students' understanding of acid-base physiology.
  • To gather student feedback on the software's features and learning utility.

Main Methods:

  • Seventy-five first-year veterinary students completed a pre- and posttest on acid-base physiology.
  • Students used the case-based Acid/Base Primer software in pairs.
  • Surveys and interviews were conducted to assess student experience and program effectiveness.

Main Results:

  • Mean scores on content understanding improved significantly from 53% (pretest) to 74% (posttest).
  • Students reported the software facilitated self-constructed understanding and peer discussion.
  • The case-based format, repetition, and scaffolded questions were highlighted as beneficial learning features.

Conclusions:

  • The Acid/Base Primer software is an effective tool for enhancing veterinary students' comprehension of acid-base physiology.
  • Educational software design principles, including case-based learning and scaffolding, positively impact student learning.
  • Findings provide guidelines for developing similar educational software in complex scientific domains.
