Separate reasoning example: a report and a conclusion
Optional method support, no numeric dataset and no submission
One PDF, due September 18 at 11:59 p.m. If I collected the same work on paper, do not upload it again.
Separate reasoning example: a report and a conclusion
Optional method support, no numeric dataset and no submission
40–55 minutes: use this example if you need help checking given details and inferences.
This short example shows a reasoning method. It has no numerical dataset and does not answer your four assigned well rows. It is optional support, not a submission.
Supplied note
“The classroom door is closed.”
What the note supports
Supported statement: The note reports that the classroom door is closed.
This sentence stays with the information supplied. It does not claim that you visited the room or observed anything else.
A conclusion that goes beyond the note
Unsupported inference: Therefore, the classroom is empty.
Limit: The note does not say whether anyone is inside. Information about the room's occupants would be needed to check that conclusion.
The problem is the missing evidence, not the writer's confidence. The note might be accurate about the door while still being insufficient to establish whether the room is empty.
Use the method in your assigned record
First report what the supplied record gives. Then ask whether a conclusion needs information the record does not give. For Parts B and C, use your own well statements, comparison and limit; do not copy the door example as a well result.
Return to today's portal lesson for the four-row record. Submit your own Parts A-C together in one PDF to Wk4 Data table: Antigen-antibody and ELISA model by September 18 at 11:59 PM. If I collected that work on paper in class, do not upload it again. The example and guided notes are not additional submissions.
Connection to PLTW
This local paper analysis supports the antigen-antibody binding and interpretation concepts in PLTW Medical Interventions Activity 1.1.5, ELISA. It does not perform the assay or certify completion of the official activity.
- PLTW Activity 1.1.5: ELISA: Existing official concept reference, not an instruction to perform the full activity
- Sign in to myPLTW: Authorized official curriculum access
- Selective binding and cross-reaction: Janeway Appendix I: introductory Immunization paragraphs; detection/measurement introduction; A-8 for epitope
- ELISA formats and measured-reference interpretation: NCATS Assay Guidance Manual: Immunoassay Formats, Control Samples and Calibration Curve Model Selection
- ELISA background: Supplementary conceptual background and control limits; no clinical algorithm or procedure adopted
- Different clinical tests use different methods: CDC: Recommended tests; background only, not personal testing advice
Submit the same work once
Submit one PDF containing Parts A-C of your model-analysis record to Wk4 Data table: Antigen-antibody and ELISA model by September 18 at 11:59 PM. If I collected this work on paper in class, do not upload a second copy. This assignment is 5 points in Daily Work. The example, guided notes and optional reflection are not separate submissions.
Wk4 Data table: Antigen-antibody and ELISA modelThis is a paper analysis of supplied illustrative labels, not a performed assay, measured calibration, patient result or completed official PLTW activity. Do not invent observations, controls or a positive/negative decision.
