The relevant program learning outcomes are from the general education core.

- Define and explain the concepts, principles, and theories of a field of science.
- Perform experiments that gather scientific information and to utilize, interpret, and explain the results of experiments and field work in a field of science

Learning themes cut across all activities and explorations in the course. These learning themes are the first three items on the course outline.

Students will be able to...

Learning Themes | ||
---|---|---|

Outcome | Materials | Sample Evidence |

Explore physical science systems using scientific methodologies | Syllabus |
Laboratory reports from laboratory 14 final practical laboratory.
Students were given a system to study and no further guidance on how to analyze the system. RB • AH • DL • SL • BS • ET • MVT |

Generate mathematical models for physical science systems | Math relations | |

Write up the results of experiments in a formal format using spreadsheet and word processing software | Rubrics |

Specific learning is centered on the laboratory experiences. Laboratory reports cited above are considered a primary measure of student performance. The final includes single numeric problems typifying that area of study. The last column below is the percent of students who answered that question correctly on the final examination; the results of the final examination item analysis.

Each final utilized a spreadsheet to randomly generate data values. A mail merge was used to produce individually unique final examinations for each and every student. The merge also generated an answer sheet for each student final, these were separated from the final and used to mark each unique exam paper.

The core of the course are the activities and laboratories. The laboratories involve a write-up using spreadsheet and word processing software. The laboratories are marked using a rubric. The course focuses on physical science as a process and method, an exploration in search of mathematical models of system behavior.

The item analysis success rate is directly related to the complexity of the problem. Problems which required only memorized recall of a single fact such as the heat conductivity of a material saw 90% of the students answering correctly. Calculations which require only a single step such as calculations of velocity had a 62% success rate. Problems which involved multiple steps and internal conversions such as determining the number of meters per minute of longitude or the speed of sound based on echo times had 17% and 21% success rates respectively.

The course also sought to impact student values in regards science, specifically the course sought to make science interesting and enjoyable. Survey results indicated that opinions and values were shifted during the term. Instuctor evaluation by the students along with student self-evaluations were also conducted.
