This learning resource is a 11 slide PowerPoint presentation on acid-base balance.
Type of Material:
The learning material is an eleven slide PowerPoint presentation, with one particularly effective graphic of acid/base ranges.
Recommended Uses:
This learning resource could supplement a classroom lecture on acid/bases. It could also be used as a prepared lecture.
Technical Requirements:
If used online, the user would need a computer connected to the Internet with a web browser. If the slides were downloaded to a personal computer, the user would need to have PowerPoint software.The program opened easily and the naviagation buttons are clear.
Identify Major Learning Goals:
The implied learnin goals include:
To identify the normal blood pH for humans.
To visualize how acids and bases interact with each other to form salts.
To discuss the influence of chemical buffer systems in the body: carbonic
acid/bicarbonates; proteins; hemaglobin; and phosphate.
To state some of the causes for metabolic and respiratory acidosis and alkalosis.
Target Student Population:
The target audience of students who already had some knowledge of acid/base interactions and wanted to apply that knowledge to human physiology. These students could include high school and college students beginning to study the acid/base balance in the body.
Prerequisite Knowledge or Skills:
Basic knowledge of chemistry would be beneficial to the learner.
Content Quality
Rating:
Strengths:
The topic is fundamental yet sometimes a difficult concept for pre-professional health science students to grasph. Graphics help the learner to visualize the processes.
Concerns:
the content offered is good, however,there is not enough depth nor breadth of information to cover the topic completely. There are no learning objectives nor summary. There is incomplete discussion of the factors which control acid/base balance.
Potential Effectiveness as a Teaching Tool
Rating:
Strengths:
The slide presentation could be used to supplement lecture, readings, homework assignments and other resources.
Concerns:
There is limited information. The discussion of the concept is incomplete. Additional graphics or animations would improve the quality of this learning resource.Educators should view the content as it may not explain he process in enough detail.
Ease of Use for Both Students and Faculty
Rating:
Strengths:
The presentation is extremely user friendly. The slides are easy to use.
Concerns:
The text and the graphic do not provide any added value over other resources that are found in textbooks and the Internet. The graphic slide for pH ranges is excellent.
