After successful completion of the course, students are able to (among others)

• describe, explain, and demonstrate advanced principles and concepts of functional programming and their application in practice.
• explicate the theoretical and practical foundations of functional programming, and to apply them for verifying and validating the correctness of functional programs.
• identify, discuss, and demonstrate in detail benefits and limitations of a (pure) functional programming style.
• solve programming tasks from small to medium size and complexity using basic and advanced concepts and principles of functional programming adequately and professionally.

The course is concerned with advanced concepts and principles of
functional programming and their applications. The lecture part of the
course stretches from functional programming principles to quality
assurance, advanced languages concepts, and applications. Regularly
assigned exercises of the tutorial part of the course give a hands-on
experience of applying the concepts and principles to problems of
suitable kind, size and complexity to get to a profound understanding
of them in theory and practice.

According to current COVID-19 restrictions and directives of the vice rectorate for academic affairs and the dean's office of academic affairs from January 26 abd January 31, 2021, the lecture course 185.A05 Advanced Functional Programming is exclusively held online. The advantages of the directness of face-to-face course meetings shall be preserved to the largest possible extent. All course and tutorial meetings will thus be held as real-time video conferences.

1. Guided self-dependent learning and practicing (online only): Guided by means of lecture and flipped classroom sessions, the self-dependent learning and practicing of the competencies described in the learning outcomes utilizing lecture notes, theoretical and practical exercises, and further self-reliantly chosen material from text books, tutorials, and scientific articles proposed for further reading.
2. Role model and feedback-oriented learning (online only): Presenting, explaining, comparing, contrasting, and rating own and others solutions of assignments in tutor-guided tutorials.
3. Self-assessment tests (online and offline, no physical presence): Tests supporting the regular self-assessment and self-reflection of one's own progress and success of learning; central and control questions.

ECTS Break Down:

The course is assigned 3.0 ECTS points. This corresponds to an average
workload of 75 hours. This average workload is divided among the
various learning activities of the course as follows (the descriptions Part I to Part VI refer to the respective parts of the course notes):

• Guided learning activities (exclusively online, 17.5h)
• Lecture: 7.0h (7 units * 1.0h)
• Flipped classroom: 3.5h (7 units * 0.5h)
• Tutorials: 7.0h (7 units * 1.0h)
• Independent learning activities (studying from home, 56.5h)
• Self-dependent acquirement of learning outcomes: 28.0h (Guide value: Part I/1.0h, Part II/6.0h, Part III/6.0h, Part IV/7.0h, Part V/7.0h, Part VI/1.0h)
• In particular: Solving assignments: 24.5h (Guide value: 4 Assignments * 3.0h, 1 Project * 15.5h)
• Project demo and oral exam preparation: 1.0h
• Project demo (exclusively online, video presence): 0.5h
• Oral exam (exclusively online, face-to-face video presence): 0.5h

The preliminary course meeting and the first lecture take place on
Thursday, 4 March 2021, from 4.15 pm to 6.00 pm (inclusive of a 15min break) via Zoom. The Zoom link has been posted as a TISS message on 1 March 2021; it can also be found on the news board for course news in TISS and in the complementary TUWEL course.

• Online/offline, without physical presence: Four rated submissions of (smaller) programming assignments.

• Online, video presence: One rated submission and demo of a (larger) project assignment.

• Online, video presence: One rated 30 minute oral examination about lecture and tutorial topics and documents (consensually, the oral exam can be replaced by an equivalent oral exam on-site, if the then valid COVID rules should allow this).

There are no other rated assessments.

Required technical equipment: Stable Internet connection, internet connectable device with audio/video receiver and transmitter.

Basic knowledge of the functional programming paradigm as
e.g. imparted in the course LVA 185.A03 "Funktionale Programmierung"
is mandatory.
