STATISTICAL MATHEMATICS AND DATA PROCESSING FOR EARTH SCIENCES

Module MATHEMATICS

Knowledge and understanding.

Students will be able to use mathematical language with rigor and understand the process of developing mathematical models in a wide range of application areas of geology. They will be able to acquire a wide range of calculation and manipulation techniques for the most common mathematical objects, such as sequences, series, limits and derivatives.

Apply knowledge and understanding.

Students will be able to acquire skills in designing and solving a model based on a real-world problem.

Expressing judgments.
Students will be challenged to express informed judgments by evaluating the appropriateness and accuracy of mathematical techniques when applied to engineering problems. They will develop the ability to critically assess and select the most suitable mathematical methods, enhancing their problem-solving skills and engineering decision-making processes.

Communication skills.
The course places a strong emphasis on developing effective communication skills, equipping students with the ability to articulate mathematical concepts and problem-solving approaches clearly and concisely. Through exercises and collaborative discussions, students will learn to convey complex mathematical ideas to both technical and non-technical audiences, a crucial skill for success in their engineering careers.

Learning skills.

Students will actively cultivate essential learning skills, including self-directed study, problem-solving strategies, and adaptability when approaching mathematical challenges. Through a variety of exercises and assessments, students will develop the ability to independently explore and apply mathematical concepts, fostering a lifelong capacity for continued learning in engineering and related disciplines.

Use and understand mathematical language with rigour.

Understand the process of mathematical model-building in a range of application areas of geological sciences.

Demonstrate skills in designing and solving a model based on a real-world problem.

Acquire a wide range of techniques of computation and manipulation of mathematical objects, such as sequences, series, limits, differential calculus in one variable.

Face-to-face lectures and individual and group works.

Information for students with disabilities and / or SLD

To guarantee equal opportunities and in compliance with the laws in force, interested students can ask for a personal interview in order to plan any compensatory and / or dispensatory measures, based on the didactic objectives and specific needs. It is also possible to contact the referent teacher CInAP (Center for Active and Participated Integration - Services for Disabilities and / or SLD) of our Department.

No prerequisites are expected.

1. Written Exam, marked out of 30 (worth 50% of the final mark)

2. Oral Exam, marked out of 30 (worth 50% of the final mark)

Criteria for assigning marks: both for the written and the oral exams, the following will be taken into account: clarity of presentation, completeness of knowledge, ability to connect different topics. The student must demonstrate that they have acquired sufficient knowledge of the main topics covered during the course and that they are able to carry out at least the simplest of the assigned exercises.

The following criteria will normally be followed to assign the grade:

Not approved: the student has not acquired the basic concepts and is not able to carry out the exercises.

18-23: the student demonstrates minimal mastery of the basic concepts, their skills in exposition and connection of contents are modest, they are able to solve simple exercises.

24-27: the student demonstrates good mastery of the course contents, their presentation and content connection skills are good, they solve the exercises with few errors.

28-30 cum laude: the student has acquired all the contents of the course and is able to explain them fully and connect them with a critical spirit; they solve the exercises completely and without mistakes.
