Inquiry Investigation: A New Approach to Laboratory Reports

Hand, B.; Keys, C. W. Inquiry Investigation: A New Approach to Laboratory Reports. Sci. Teach. 1999, 66, 27-29.

The authors have developed a science writing heuristic the follows a path of inquiry to be used for student investigations.

The Science Writing Heuristic, part I
A template for teacher-designed activities to promote laboratory understanding.

  1. Exploration of pre-instruction understanding through individual or group concept mapping. 
  2. Pre-laboratory activiitesm including informal writing, makeing observations, brainstorming, and posing questions.
  3. Participation in laboratory activity (can be student generated procedure).
  4. Negotiation phase I - writing personal meanings for laboratory activity (lab journals?).
  5. Negotiation phase II - sharing and comparing data interpretations in small groups (for example making group charts).
  6. Negotiation phase III - comparing science ideas to textbooks or other printed resources (for example writing group notes in response to focus questions).
  7. Negotiation phase IV - individual reflection and writing (for example, creating a presentation such as a poster or report or a larger audience).
  8. Exploration of post-instruction understanding through concept mapping
The writing heuristic, part II
A template for student thinking.
  1. Beginning ideas - what are my questions?
  2. Tests - what did I do?
  3. Observations - what did I see?
  4. Claims - what can I claim?
  5. Evidence - How do I know? Why am I making these claims?
  6. Reading - How do my ideas compare with other ideas?
  7. Reflection - How have my ideas changed?

"The SWH give students multiple opportunities to develop conceptual understanding by integrating practical laboratory work with peer group discussion, writing, and reading." p. 28

"Next students engage in pre-investigation activities, which might include making initial observations or explorations, writing questions and brainstorming ideas."

"Prompts 4 & 5 direct students to construct a deeper understanding of their laboratory findings by stating the knowledge, claims, or understandings gained from the lab and providing a coherent set of reasons for those claims. Prompt 6 guides students to check their explanations with an authority figure such as a text book or teacher."

-Note: while I love the idea of students being the final authority on their findings, I do think the final step of researching the phenomena explored and comparing their results to previously established results is a necessary step at this stage.

What if I need to see a doctor today? What is online lab viewing? Will I have +++++++++
access to all my lab reports? How do I update my personal contact information?do my lab report

all outcomes of lab experiments. These info ... If you have an answer

just take down some notes so that you will not forger it in your

report. Below are ...
