Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

• Theory, initial concepts and techniques will be introduced during lectures and seminars.
• Much of the learning, understanding and consolidation will take place through the use of structured exercises during seminar sessions and students' own time.
• Short in-class tests covering aspects of the previous week’s work will be set usually on a weekly basis. These tutor marked tests allow rapid feedback and build confidence. Whilst the marks accumulate towards the overall portfolio mark, the tests also perform a formative role enabling students to reflect on their own performance, identify areas of weakness, and practice some of the skills and techniques which will be required in the longer invigilated tests.
• Small coursework tasks developing or consolidating the previous week’s work will be set on a weekly or fortnightly basis. Like the tests, these tutor marked tasks allow rapid feedback and build confidence. Additionally, they ensure that students master specific skills to an appropriate level prior to their requirement in more complex tasks or other modules. As an example, the first task usually involves the plotting of three graphs. Tutor feedback from this task ensures that students are ready to draw further graphs in Biology or Chemistry.
• Students undertake a project in which they explore research questions by applying appropriate statistical concepts and techniques that they have been taught, to numerical data they have obtained. They then interpret their statistical findings to reach meaningful conclusions. The project, thus, both consolidates and assesses a range of statistical procedures.
• Manipulative skills and ability to recall, select and apply mathematics and statistics will be assessed by the two invigilated tests in addition to the portfolio of tasks and in-class tests.
• The Portfolio covers SSK 1-11, SSS1-4, KS 2-4
• The Invigilated Tests cover SSK 1-11, SSS1-4, KS2-4
• The Project using statistics covers SSK6-9, SSS1, SSS4, SSS5, KS 1-4

Teaching Methods and Learning Hours

Summative Assessment

Formative Assessment:

Students will be given self-testing units on a weekly basis in the form of worksheets with answers and/or DUO quizzes. Portfolio tests and tasks with a rapid marking turnaround fulfill a formative as well as summative role (See Section 14). Students have access to two or more mock papers and answers to help prepare for the invigilated tests. The project is submitted in two parts so that early feedback on the Introduction and method can be used to inform the second part of the project. *Attendance at all activities marked with this symbol will be monitored.
