Assessment pattern

Alternative Assessment

Failure in the laboratory may require re-assessment through a defined practical examination

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate that they have successfully met the learning outcomes of the module (see above). Thus, the summative assessment for this module consists of:

• Laboratory report 1: Assessment of practical (experimental) skills and the ability to write scientific reports (LO2, LO3)

• Laboratory report 2: Assessment of practical (experimental) skills and the ability to write scientific reports (LO2, LO3)

• Examination: Assessing LO1 and LO2

Formative assessment

Formative assessment is provided for all types of summative assessment mentioned above. Thus a portion of the experimental sessions and the laboratory reports related to them are formatively assessed. Formative assessment is also provided in tutorials where seen and unseen questions are discussed in preparation for the final examination. Formative assessment also takes place in lectures where opportunities for problem solving allow group work and discussion. This is also provided through weekly online quizzes with associated automatic feedback.

Feedback

Feedback is provided orally throughout the duration of the module in every opportunity (lecture, tutorial, practical session) including one-to-one meetings arranged on student request. Feedback is provided in writing

• After completion of each formative and summative laboratory report

• After completion of tutorials

Module aims

• provide an understanding of the principles underlying elementary quantum theory and their experimental foundation;
• introduce basic principles of current atomic structure;
• develop further understanding of how and why reactions occur.

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

• present the theory and foster enquiry and consolidation through discussion,

• enhance problem solving skills,

• enhance practical (laboratory) skills including the ability to write scientific reports

• give a comprehensive understanding of the standards required for successful completion of the module

The learning and teaching methods include:

• Lectures: Powerpoint presentations and discussion (including some problem solving)

• Tutorials: discussion of pre-set and of unknown questions

• Practical (laboratory) sessions (and associated pre-lab lectures): Experimental work on topics including spectrometric analysis, determination of thermodynamic parameters and investigation of reaction kinetics.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
