Manual pages 125-148 APSC 100 Introduction to Experimentation ASSESSMENT AND MARKING You must attend all lab periods and complete all formal reports/assignments. Attendance will be taken. You will receive an N/C for APSC100 if you miss ANY lab or don’t hand the completed assignment/formal report in. Complete the form on the website to request permission to make up a missed lab if you are sick or have a valid excuse. This form will enable you to make up the lab with another section If your partner is away sick then you can either do the lab on Manual pages 4-5 your own or join with another group. APSC 100 Introduction to Experimentation ASSESSMENT AND GRADING A grade is awarded (A, B, C, D) for each assignment/report. Your overall grade is a weighted average of individual marks. •error propagation worksheet WEIGHTING 5% •tutorial labs (2 of these): 8% each •Formal lab reports (3 of these - labs 1,3,6) 16% each •In-lab analysis work (3 of these - labs 2,4,5) 5% each •project experiments (effort and formal report) 16% Manual pages 4-5 APSC 100 Introduction to Experimentation ASSESSMENT AND MARKING for formal reports How is it graded? •half of the grade is based on your conveyed comprehension of the lab (description of concepts, data analysis, error analysis, etc.) •half of the grade is based on presentation: written English, organization, data presentation, concise explanation, table and figure format – APSC 100 Introduction to Experimentation ASSESSMENT AND MARKING for formal reports What do we expect in a formal report? A typed, technical document that explains scientific principles, procedures and results rigorously and concisely, illustrating your understanding of the subject matter. Resources to help you: Appendix 2 (Manual) contains •A guide to writing formal lab reports •A formal report example - page 83 (you can also download this from the web and use it as a template for your own formal reports) APSC141 will cover basic report writing concepts and organization in the next 2 weeks. The grading criteria (for A, B, etc) that the TA’s use is in the manual pg 5 – also see page 91 in the manual for the TA checklist. Northey and Procter’s book – ‘Writer’s choice’ - has a chapter on report writing and also Manual pages 4-5, 75-91 provides general writing tips APSC 100 Introduction to Experimentation Academic dishonesty THE PENALTY FOR COPYING ANY PART OF ANOTHER LAB REPORT IS TO REPEAT APSC100 NEXT YEAR. This signed statement is needed on the front of all reports: “I verify that this formal report is my own individual work and has not been copied in whole or in part from another source (with the possible exception of equations and/or diagrams from the experimental descriptions on the APSC100 website). Furthermore, I have not and will not lend this report (electronic or hardcopy) to any other student, either now or in the future ” COPYCHECKER WEBSITE: in addition to handing in a hardcopy of your formal reports, a copy must be sent to our copychecker website. The TAs will verify that the hardcopy and e-copy are the same before they mark your report. The copychecker stores your report in a database and compares it against all others to identify similarities. APSC 100 Introduction to Experimentation To avoid repeating APSC100: Do not borrow a lab from anyone. Do not lend your lab to anyone!! IF YOU LEND YOUR LAB TO SOMEONE AND IT GETS COPIED, YOU CAN RECEIVE THE SAME PENALTIES AS IF YOU WERE THE STUDENT THAT COPIED IT. Share your data with your partner in the lab, then write your reports completely independently with no interaction!!! APSC 100 Introduction to Experimentation What should I do before next week? •Complete the error propagation worksheet and hand in at Stirling Hall by 3:00pm Monday next week Tutorial help is available this week- bottom of the error worksheet for details (don’t wait for this, though - start ASAP!!) •read pgs 8-17 (tutorial lab #1) before your tutorial lab next week •Transfer students see me now or contact me later to sign up for a special “modified module 2” session which runs in the evenings next term Scheduled labs for APSC100 Module 2 start NEXT WEEK. The schedule for weeks 2 and 3 is below.
