;[http://www.seas.upenn.edu/~cis194/lectures.html CIS 194: Introduction to Haskell (Spring 2013)]: An excellent tutorial to Haskell for beginners given as a course at UPenn by the author of the Typeclassopedia and Diagrams, Brent Yorgey. More compact than LYAH and RWH, but still communicates both basics and some notoriously unfamiliar concepts effectively.<br />
<br />
;[http://learnyouahaskell.com Learn You a Haskell for Great Good! (LYAH)]<br />
: Nicely illustrated tutorial showing Haskell concepts while interacting in GHCi. Written and drawn by Miran Lipovača.<br />
<br />
;[http://book.realworldhaskell.org/ Real World Haskell (RWH)]<br />
: A free online version of the complete book, with numerous reader-submitted comments. RWH is best suited for people who know the fundamentals of Haskell already, and can write basic Haskell programs themselves already. It makes a great follow up after finishing LYAH. It can easily be read cover-to-cover, or you can focus on the chapters that interest you most, or when you find an idea you don't yet understand.<br />
<br />

:A Haskell Tutorial, by Jonathan Tang. Most Haskell tutorials on the web seem to take a language-reference-manual approach to teaching. They show you the syntax of the language, a few language constructs, and then have you construct a few simple functions at the interactive prompt. The "hard stuff" of how to write a functioning, useful program is left to the end, or sometimes omitted entirely. This tutorial takes a different tack. You'll start off with command-line arguments and parsing, and progress to writing a fully-functional Scheme interpreter that implements a good-sized subset of R5RS Scheme. Along the way, you'll learn Haskell's I/O, mutable state, dynamic typing, error handling, and parsing features. By the time you finish, you should be fairly fluent in both Haskell and Scheme.<br />

In Krzysztof Apt, Pieter Hartel, and Paul Klint, editors, First International Conference on Declarative Programming Languages in Education. Springer-Verlag, September 1997. <br> <STRONG>Abstract:</STRONG> This paper introduces a problem solving method for teaching functional programming, based on Polya's `How To Solve It', an introductory investigation of mathematical method. We first present the language independent version, and then show in particular how it applies to the development of programs in Haskell. The method is illustrated by a sequence of examples and a larger case study. <br />

;[http://www.cse.unsw.edu.au/~chak/papers/CK02a.html The Risks and Benefits of Teaching Purely Functional Programming in First Year]<br />
:By [http://www.cse.unsw.edu.au/~chak/ Manuel M. T. Chakravarty] and [http://www.cse.unsw.edu.au/~keller/ Gabriele Keller]. Journal of Functional Programming 14(1), pp 113-123, 2004. An earlier version of this paper was presented at Functional and Declarative Programming in Education (FDPE02). <br> <strong>Abstract</strong> We argue that teaching purely functional programming as such in freshman courses is detrimental to both the curriculum as well as to promoting the paradigm. Instead, we need to focus on the more general aims of teaching elementary techniques of programming and essential concepts of computing. We support this viewpoint with experience gained during several semesters of teaching large first-year classes (up to 600 students) in Haskell. These classes consisted of computer science students as well as students from other disciplines. We have systematically gathered student feedback by conducting surveys after each semester. This article contributes an approach to the use of modern functional languages in first year courses and, based on this, advocates the use of functional languages in this setting.<br />

This tutorial aims to explain the concept of a monad and its application to functional programming in a way that is easy to understand and useful to beginning and intermediate Haskell programmers. Familiarity with the Haskell language is assumed, but no prior experience with monads is required. <br />
<br />
;[[Monads as computation]]<br />
:A tutorial which gives a broad overview to motivate the use of monads as an abstraction in functional programming and describe their basic features. It makes an attempt at showing why they arise naturally from some basic premises about the design of a library.<br />
<br />
;[[Monads as containers]]<br />
:A tutorial describing monads from a rather different perspective: as an abstraction of container-types, rather than an abstraction of types of computation.<br />

<br />
;[http://en.wikibooks.org/wiki/Write_Yourself_a_Scheme_in_48_Hours Write Yourself a Scheme in 48 Hours in Haskell]<br />
:A Haskell Tutorial, by Jonathan Tang. Most Haskell tutorials on the web seem to take a language-reference-manual approach to teaching. They show you the syntax of the language, a few language constructs, and then have you construct a few simple functions at the interactive prompt. The "hard stuff" of how to write a functioning, useful program is left to the end, or sometimes omitted entirely. This tutorial takes a different tack. You'll start off with command-line arguments and parsing, and progress to writing a fully-functional Scheme interpreter that implements a good-sized subset of R5RS Scheme. Along the way, you'll learn Haskell's I/O, mutable state, dynamic typing, error handling, and parsing features. By the time you finish, you should be fairly fluent in both Haskell and Scheme.<br />

In Krzysztof Apt, Pieter Hartel, and Paul Klint, editors, First International Conference on Declarative Programming Languages in Education. Springer-Verlag, September 1997. <br> <STRONG>Abstract:</STRONG> This paper introduces a problem solving method for teaching functional programming, based on Polya's `How To Solve It', an introductory investigation of mathematical method. We first present the language independent version, and then show in particular how it applies to the development of programs in Haskell. The method is illustrated by a sequence of examples and a larger case study. <br />

Hartel and Rinus Plasmeijer, editors, Functional Programming Languages in Education, LNCS 1022, pages 85-102. Springer-Verlag, December 1995. <br> <STRONG>Abstract:</STRONG> This paper discusses our experience in using a functional language in topics across the computer science curriculum. After examining the arguments for taking a functional approach, we look in detail at four case studies from different areas: programming language semantics, machine architectures, graphics and formal languages. <br />

;[http://www.cse.unsw.edu.au/~chak/papers/CK02a.html The Risks and Benefits of Teaching Purely Functional Programming in First Year]<br />
:By [http://www.cse.unsw.edu.au/~chak/ Manuel M. T. Chakravarty] and [http://www.cse.unsw.edu.au/~keller/ Gabriele Keller]. Journal of Functional Programming 14(1), pp 113-123, 2004. An earlier version of this paper was presented at Functional and Declarative Programming in Education (FDPE02). <br> <strong>Abstract</strong> We argue that teaching purely functional programming as such in freshman courses is detrimental to both the curriculum as well as to promoting the paradigm. Instead, we need to focus on the more general aims of teaching elementary techniques of programming and essential concepts of computing. We support this viewpoint with experience gained during several semesters of teaching large first-year classes (up to 600 students) in Haskell. These classes consisted of computer science students as well as students from other disciplines. We have systematically gathered student feedback by conducting surveys after each semester. This article contributes an approach to the use of modern functional languages in first year courses and, based on this, advocates the use of functional languages in this setting.<br />

:A Haskell Tutorial, by Jonathan Tang. Most Haskell tutorials on the web seem to take a language-reference-manual approach to teaching. They show you the syntax of the language, a few language constructs, and then have you construct a few simple functions at the interactive prompt. The "hard stuff" of how to write a functioning, useful program is left to the end, or sometimes omitted entirely. This tutorial takes a different tack. You'll start off with command-line arguments and parsing, and progress to writing a fully-functional Scheme interpreter that implements a good-sized subset of R5RS Scheme. Along the way, you'll learn Haskell's I/O, mutable state, dynamic typing, error handling, and parsing features. By the time you finish, you should be fairly fluent in both Haskell and Scheme.<br />

:By Eric Etheridge. From the intro: "This tutorial assumes that the reader is familiar with C/C++, Python, Java, or Pascal. I am writing for you because it seems that no other tutorial was written to help students overcome the difficulty of moving from C/C++, Java, and the like to Haskell."<br />
<br />
;[http://www.ibm.com/developerworks/linux/tutorials/l-hask/ Beginning Haskell] <br />
:From IBM developerWorks. This tutorial targets programmers of imperative languages wanting to learn about functional programming in the language Haskell. If you have programmed in languages such as C, Pascal, Fortran, C++, Java, Cobol, Ada, Perl, TCL, REXX, JavaScript, Visual Basic, or many others, you have been using an imperative paradigm. This tutorial provides a gentle introduction to the paradigm of functional programming, with specific illustrations in the Haskell 98 language. (Free registration required.)<br />

In Krzysztof Apt, Pieter Hartel, and Paul Klint, editors, First International Conference on Declarative Programming Languages in Education. Springer-Verlag, September 1997. <br> <STRONG>Abstract:</STRONG> This paper introduces a problem solving method for teaching functional programming, based on Polya's `How To Solve It', an introductory investigation of mathematical method. We first present the language independent version, and then show in particular how it applies to the development of programs in Haskell. The method is illustrated by a sequence of examples and a larger case study. <br />

Hartel and Rinus Plasmeijer, editors, Functional Programming Languages in Education, LNCS 1022, pages 85-102. Springer-Verlag, December 1995. <br> <STRONG>Abstract:</STRONG> This paper discusses our experience in using a functional language in topics across the computer science curriculum. After examining the arguments for taking a functional approach, we look in detail at four case studies from different areas: programming language semantics, machine architectures, graphics and formal languages. <br />
<br />
;[http://www.cse.unsw.edu.au/~chak/papers/CK02a.html The Risks and Benefits of Teaching Purely Functional Programming in First Year]<br />
:By [http://www.cse.unsw.edu.au/~chak/ Manuel M. T. Chakravarty] and [http://www.cse.unsw.edu.au/~keller/ Gabriele Keller]. Journal of Functional Programming 14(1), pp 113-123, 2004. An earlier version of this paper was presented at Functional and Declarative Programming in Education (FDPE02). <br> <strong>Abstract</strong> We argue that teaching purely functional programming as such in freshman courses is detrimental to both the curriculum as well as to promoting the paradigm. Instead, we need to focus on the more general aims of teaching elementary techniques of programming and essential concepts of computing. We support this viewpoint with experience gained during several semesters of teaching large first-year classes (up to 600 students) in Haskell. These classes consisted of computer science students as well as students from other disciplines. We have systematically gathered student feedback by conducting surveys after each semester. This article contributes an approach to the use of modern functional languages in first year courses and, based on this, advocates the use of functional languages in this setting.<br />
