Learning Goals: • The student will learn to distinguish between the different heart sounds associated with different diseases.
Target Student Population: College technical programs or courses that have adequate prerequisite knowledge.
Prerequisite Knowledge or Skills: Anatomy and physiology background for heart and lungs. Good pc sound system and the knowledge to adjust it.
Type of Material: Simulation
Recommended Uses: Use in class first and then supplement as homework for first-timers. Upper level students could use as homework. Could be used as a sound/audio assessment quiz
Technical Requirements: Quick Time plug-in (does not work in Firefox)

Evaluation and Observation

Content Quality

Rating: 3.75 stars
Strengths: Sound based tutorial that is adequate for audio only uses. • The audio is very accurate • The material is easy to read
Concerns: This material is in desperate need of visual materials to supplement the sounds. As a tutorial the material uses many terms, but no visual graphics to distinguish the ekg waves associated with the audio sounds and where to find the best sounds.

Potential Effectiveness as a Teaching Tool

Rating: 4 stars
Strengths: Sounds appear to be relevant to the disease state. Could be used as an audio test or assessment only.
Concerns: No pictures and no prerequisite knowledge stated. Requires plug in and in the days of mp3 players is very outdated to not present the media in more than one format and with the option to select that media. Overbearing sound playing constantly is irritating. Much more current information can be found on the net including YouTube with pictures and full media that would require less cognitive load on the student.

Ease of Use for Both Students and Faculty

Rating: 3.5 stars
Strengths: Short, sound quality adequate
Concerns: Plug in required, without adequate usability in all browsers. Outdated technically compared to videos on YouTube etc.

Other Issues and Comments: This material needs a lot of updating and is not current compared to other materials available at this time. Its main value is in the sounds only, not the explanations that have no illustrations to accompany the sounds in the product.
