Teaching methods and learning activities

Carry out well established lab tests and protocols. Short useful expositions of suitable procedures spread. Use of two different laboratories in rotating system.
Follow and guide work students groups through their pre-defined thematic project approach

Evaluation Type

Distributed evaluation without final exam

Eligibility for exams

- Laboratory classes are compulsory for all the students, including the ones under article 4, items a) and b).
The minimum grade of the practical component is 10 marks.

Calculation formula of final grade

Final grade of the course:
NF = 0.25*P + 0.75*LC)
Where,
NF – Final grade of the course
P - Project grade
LC - Laboratorial component

Practical component is obtained as follows:

LC=0.5*REL+0.5*AC
where
REL - weighed grade of two reports of the practical assignments made, respectively REL1 and REL2, one at the Metallurgical Department laboratory, another at the MIning Department laboratory; REL =0.5*REL1+0.5*REL2
and
AC – continuous evaluation component, a personal opinion obtained by analysing student behaviour in the lab, looking at its notebook, evaluating answers to some questions if necessary ...

Examinations or Special Assignments

The final grade of the course includes the evaluation of the following components:

Laboratorial component: Continuous evaluation of practical classes (AC) and two complete reports per group (REL); The page limit is 10.
AC – The students must have a laboratory exercise book where they will do a previous preparation of the assignment, take notes (data and comments), do the calculus and present a conclusion for each assignment (the previous preparation is done at home and the rest in the laboratory). The exercise book will be evaluated in each class, as well as the laboratory performance, which will function as a support to the attribution of the continuous evaluation grade (AC). As an alternative for the laboratory exercise book evaluation, the teachers can choose to demand the presentation of a short report (2 A4 pages maximum) on the seven days after the assignment is done.
REL – reports will be obligatorily on the Metallurgy and Materials Laboratory module (REL1) and on the Mining Laboratory module (REL2)
All the classifications will range 0-20.

Special assessment (TE, DA, ...)

Not applicable, since it is not expected that special students frequent this subject.

Classification improvement

Not foreseen

Observations

All the laboratorial procedures to be used at the practical sessions in the laboratories will be loadable at the site of LCAI in the SiFEUP under the format of either .doc or .pdf files.
