The digital microscope: a tool for teaching laboratory skills in distance learning courses

Area of Science:

• Neuroscience
• Pharmacology
• Distance Learning Pedagogy

Background:

• Undergraduate science students typically develop practical skills in laboratory settings.
• Distance learning students often lack access to hands-on laboratory experiences, risking skill deficits.
• Traditional universities may have limitations on animal experimentation, impacting practical training.

Purpose of the Study:

• To evaluate the effectiveness of a Digital Microscope as a tool for distance learning science students.
• To assess the ability of students to collect and analyze experimental data using the Digital Microscope.
• To investigate the differential effects of cocaine and amphetamine on Fos positive cells in the rat caudate putamen.

Main Methods:

• Students used a Digital Microscope to count Fos positive cells in specific regions of the rat brain.
• Data were collected from small groups of students investigating the effects of cocaine and amphetamine.
• Student-collected data were compared with tutor-collected data, and feedback was gathered via questionnaires.

Main Results:

• Student cell counts were higher than tutor counts, but the relationships between experimental groups were maintained.
• The majority of students and tutors reported gaining valuable practical skills, including data acquisition and error identification.
• Both students and tutors perceived the Digital Microscope as adding significant value to the course.

Conclusions:

• The Digital Microscope is a valuable tool for simulating laboratory experiments in distance learning science education.
• This technology enhances practical skill development, data analysis capabilities, and understanding of experimental principles.
• The Digital Microscope offers a viable alternative for practical training in both distance learning and traditional settings with limited animal experimentation.
