Assessment Matrix
Other Information
This course is graded in accordance with competency-based assessment, but which also utilise graded assessment
CHD Competent with High Distinction (80 – 100%)
CDI Competent with Distinction (70 – 79%)
CC Competent with Credit (60 – 69%)
CAG Competency Achieved – Graded (50 – 59%)
NYC Not Yet Competent
DNS Did Not Submit for assessment
• To pass the course you need to pass, on average, each type of assessment (exams, pracs and assignments etc.) For example, if there are two exams you need to have an average of 50% to pass and you also need to have passed the other assessment types. You can’t make up marks from one type of assessment to another (e.g. pass the exams but fail the prac component).
• Late work that is submitted without an application for an extension (see below) will not be corrected.
• APPLICATION FOR EXTENSION OF TIME FOR SUBMISSION OF ASSESSABLE WORK - A student may apply for an extension of up to 7 days from the original due date. They must lodge the application form (available online http://www1.rmit.edu.au/students/assessment/extension) at least 24 hours before the due date. The application is lodged with the School Admin Office on Level 6, Bdg 51. Students requiring longer extensions must apply for SPECIAL CONSIDERATION.
• For missed assessments such as exams- you (& your doctor if you are sick) must fill out a special consideration form. This form must be lodged online with supporting evidence prior to, or within, 48 hours of the scheduled time of examination http://www1.rmit.edu.au/students/specialconsideration
What does “all assessments must be passed” mean exactly?
It is your responsibility to understand exactly what you need to do to pass the course, but hopefully the information below will make things clear… if you need more information, please ask a teacher J
This means you need to pass, on average, each type of assessment listed in the table ie:
- Average exam mark (2 exams) is a pass,
- Average Lab report mark (2 reports) is a pass,
- Satisfactory completion of all required Lab Skills (outlined below) AND
- Logbook record keeping is a pass.
If you miss a Lab class you need to provide a copy of your medical certificate or other evidence (court appearance, funeral notice, statutory declaration) to the teacher.
Quizzes are optional in this course.
The quizzes are designed to give you feedback about how well you are understanding the material. Therefore it is highly recommended that you complete the quizzes.
Logbook
Students must attend and record at least 80% of the labs. Records must be finalized within 2 weeks of the experiment. Students must write up their logbook for all labs that they attend to show that they are proficient at recording experiments in a timely manner.
The marking guide shows how the mark will be generated. Only records produced within 2 weeks of the experiment will be graded. Students can self-assess their logbook records using the logbook checklist.
A requirement of this assessment task is that students collect evidence that they have prepared solutions and collected data that shows each solution is fit for purpose. Only some experiments are suitable for this purpose (see checklist). At least 1 of the suitable experiments needs to be amongst those recorded to meet the criteria.
If you are absent or have a medical certificate or other acceptable paperwork to cover an absence, this should be recorded in the logbook checklist.
Lab Reports
If you miss either of the Lab report classes you will only be eligible to write up/catch up the Lab if you provide a medical certificate or if special consideration is granted. For this to occur you need to discuss your situation with the teacher as soon as possible. Other reasons for missing a write up Lab do not mean that you can write up a different report.
Lab reports are due in the session where the activity is done.
There is a document for you to fill out for the report.
Lab Skills Assessment
Lab skills are assessed each week. As well as attending 80% of classes, particular skills must be achieved with the results generated to the required accuracy and precision. The required procedures are: Three solutions must be standardized and used in its titration, a titration curve must be produced and used to find an equivalence point, and a serial dilution done and verified by spectrophotometry. Accuracy & Precision requirements will be defined during each lab class using class data.
If you miss an assessment session note that catch up sessions are only available to students if a medical certificate for the original assessment date or other evidence (court appearance, funeral notice, statutory declaration) has been presented. Note some catch up days are in the revision weeks, so it is to your advantage to attend the original classes if possible to give yourself more time to revise for the exam.
