The HPI concept inventory is a two-tierd concept inventory developed and validated by the HPI Teaching Team.
The HPI-CI is a multiple choice test, coupled with requests for students to explain their response choice. The inventory targets students misconceptions related to the13 HPI concepts.The inventory was developed by our team using a collaborative stepwise process.
Host-Pathogen Interaction (HPI) concepts
1. The structural characteristics of a microbe are important in the pathogenicity of that microbe.
2. Diverse microbes use common themes to interact with the environment (host).
3. Microbes respond to forces of natural selection. Important responses include changes in virulence and antibiotic resistance.
4. Microbes adapt/respond to environment by altering gene expression.
5. Microbes have various strategies to cause disease.
6. Pathogens and host have evolved in a mutual fashion.
7. The cell wall and the cell membrane affect the bacterial response to the environment.
8. There is a distinction between a pathogen and a nonpathogen.
9. The environment will a ffect the phenotype (pathogenicity) of a bacterium.
10. Microbes adapt/respond to the environment by altering their metabolism.
11. Immune response has evolved to distinguish between self and nonself.
12. Immune response recognizes general properties (common themes vs. specific attributes: innate vs. adaptive).
13. Immune response memory is specific
We have used the inventory as a pre- test and a post-test in our HPI courses. The concept inventory allows analysis of student learning and gives insight into student misconceptions.The communal analysis of the data during team meetings has been a powerful faculty development tool and motivator for curriculum design projects.
The University of Maryland HPI teaching team has developed a collaboration with the Virginia Tech Microbiology Teaching Team led by Professor Ann Stevens to use data generated by the HPI concept inventory to catalog student misconceptions.
The HPI Concept Inventory is available. As with other similar concept inventories, the HPI-CI is most useful when considered as a faculty development tool: where use of the inventory is coupled
to review and discussion of the data among course instructors.
