Construction and Educational Impact of Plastination Models of the Limbic System, Basal Nuclei, Cerebellum, and Human Spinal Cord

Purpose:

This educational trial aims to assess whether plastination models for neuroanatomy training (limbic system, basal ganglia, cerebellum, spinal cord)" improve medical students' understanding of central nervous system anatomy compared to traditional educational methods. It will also evaluate student satisfaction with this teaching tool.

Key Questions:

1. Do plastination models for neuroanatomy training (limbic system, basal ganglia, cerebellum, spinal cord) enhance test scores in neuroanatomy examinations? 2. How do students perceive the educational value of these models?

Study Design:

Researchers will compare two teaching methods:

* Intervention group: Learns using plastination models for neuroanatomy training (limbic system, basal ganglia, cerebellum, spinal cord) * Control group: Learns using standard 2D atlases, power point and plastic models

Participants will:

1. Complete a pre-intervention anatomy knowledge test 2. Attend 4 weekly neuroanatomy sessions using their assigned method 3. Take a post-intervention exam and satisfaction survey 4. Participate in focus groups about their learning experience

Treatment and study plan

Plastination Model Group

Behavioral

Model Specifications:

"S10 silicone plastination models of brainstem structures (1:1 scale) with:

  • Sectioned at 2mm intervals to reveal internal architecture

Traditional Methods Group

Behavioral
  • Netter's Atlas of Human Anatomy (9th ed.)
  • Standardized PowerPoint lectures

Primary outcomes

  1. Change in neuroanatomy knowledge scores assessed by the "Neuroanatomy Knowledge Assessment Test

    Time frame: Baseline, Week 4 post-intervention

    Scale Title: Neuroanatomy Knowledge Assessment Test (NKAT). Score Range: 0 (no correct answers) to 15 (all answers correct). Interpretation: Higher scores indicate better neuroanatomy knowledge (better outcome).

Secondary outcomes

  1. Spatial understanding assessment

    Time frame: Post-intervention only

    Method: 3D spatial reasoning test (modified Vandenberg scale)

    Scoring: 1-5 Likert scale for structure identification accuracy

  2. Student satisfaction assessed by the 10-item Student Satisfaction Survey (SSS)

    Time frame: Immediately after the intervention (Day 1)

    • Score Range: 1 (strongly disagree) to 5 (strongly agree).
    • Interpretation: Higher scores indicate greater satisfaction (better outcome).
