ConceptThe goal of the worksop/tutorial is to introduce participants to the fundamentals of Procedural Content Generation (PCG) based on generative grammars, have them experience an example of such a system first-hand, and discuss the potential of this approach for various areas of procedural content generation for games. The principles and examples are based on Ludoscope, a software tool developed at the HvA by Dr. Joris Dormans, e.a.Duration: 2 hoursOverviewWe will use the first 30 minutes to explain the basics of how to use generative grammars to generate levels. The principles of these grammars and model transformations will be demonstrated by means of the level generation system of Spelunky, which we have modeled in Ludoscope.Spelunky focuses solely on the generation of geometry, but grammar-based systems can also be used to transform more abstract concepts of level design into level geometry. In the next hour, the participants will be able to get some hands-on experience with Ludoscope. The assignment will be to generate a Mario-like level based on specific requirements, adapted to the interests of workshop participants.Finally, we are interested in the participants’ evaluation of this approach to PCG. We will use the last 20 minutes to discuss alternative techniques, and possible applications to other areas of PCG, like asset creation, scripting and game generation.Workshop participants are asked to bring a (PC) laptop to work on during the workshop, and are encouraged to work in pairs.

This paper investigates strategies to generate levels for action-adventure games. For this genre, level design is more critical than for rule-driven genres such as simulation or rogue-like role-playing games, for which procedural level generation has been successful in the past. The approach outlined by this article distinguishes between missions and spaces as two separate structures that need to be generated in two individual steps. It discusses the merits of different types of generative grammars for each individual step in the process. Notably, the approach acknowledges that the online generation of levels needs to be tailored strictly to the actual experience of a player. Therefore, the approach incorporates techniques to establish and exploit player models in actual play.

Grammar-based procedural level generation raises the productivity of level designers for games such as dungeon crawl and platform games. However, the improved productivity comes at cost of level quality assurance. Authoring, improving and maintaining grammars is difficult because it is hard to predict how each grammar rule impacts the overall level quality, and tool support is lacking. We propose a novel metric called Metric of Added Detail (MAD) that indicates if a rule adds or removes detail with respect to its phase in the transformation pipeline, and Specification Analysis Reporting (SAnR) for expressing level properties and analyzing how qualities evolve in level generation histories. We demonstrate MAD and SAnR using a prototype of a level generator called Ludoscope Lite. Our preliminary results show that problematic rules tend to break SAnR properties and that MAD intuitively raises flags. MAD and SAnR augment existing approaches, and can ultimately help designers make better levels and level generators.

This paper addresses the procedural generation of levels for collaborative puzzle-platform games. To address this issue, we distinguish types of multiplayer interaction, focusing on two-player collaboration, and identify relevant game mechanics for a puzzle-platform game, addressing player movement, interaction with moving game objects, and physical interaction involving both players. These are further formalized as game design patterns. To test the feasibility of the approach, a level generator has been implemented based on a rule-based approach, using the existing tool called Ludoscope and a prototype game developed in the Unity game engine. The level generation procedure results in over 3.7 million possible playable level variations that can be generated automatically. Each of these levels encourages or even requires both players to engage in collaborative gameplay.

As multimedia gradually becomes more and more an integrated part of video conferencing systems, the use of multimedia integrated desktop video conferencing technology (MIDVCT) will open up new educational possibilities for synchronous learning. However, the possibilities and limitations of this technology must be clearly understood so that it can be used to maximize possible pedagogical benefits and reduce possible pedagogical limitations. This paper analyses the process of integrating MIDVCT in a first-year English language course, and offers insights into theoretical underpinnings of multimedia learning from two perspectives: the generative theory of multimedia learning and the cognitive overload theory. The data discussed in this paper have been drawn from a study which took place in a cross institutional setting at Fontys University of Applied Sciences, The Netherlands. The data were collected and analyzed according to a qualitative approach.

Teacher beliefs have been shown to play a major role in shaping educational practice, especially in the area of grammar teaching―an area of language education that teachers have particularly strong views on. Traditional grammar education is regularly criticized for its focus on rules-of-thumb rather than on insights from modern linguistics, and for its focus on lower order thinking. A growing body of literature on grammar teaching promotes the opposite, arguing for more linguistic conceptual knowledge and reflective or higher order thinking in grammar pedagogy. In the Netherlands, this discussion plays an important role in the national development of a new curriculum. This study explores current Dutch teachers’ beliefs on the use of modern linguistic concepts and reflective judgment in grammar teaching. To this end, we conducted a questionnaire among 110 Dutch language teachers from secondary education and analyzed contemporary school textbooks likely to reflect existing teachers’ beliefs. Results indicate that teachers generally appear to favor stimulating reflective judgement in grammar teaching, although implementing activities aimed at fostering reflective thinking seems to be difficult for two reasons: (1) existing textbooks fail to implement sufficient concepts from modern linguistics, nor do they stimulate reflective thinking; (2) teachers lack sufficient conceptual knowledge from linguistics necessary to adequately address reflective thinking.

A level designer typically creates the levels of a game to cater for a certain set of objectives, or mission. But in procedural content generation, it is common to treat the creation of missions and the generation of levels as two separate concerns. This often leads to generic levels that allow for various missions. However, this also creates a generic impression for the player, because the potential for synergy between the objectives and the level is not utilised. Following up on the mission-space generation concept, as described by Dormans, we explore the possibilities of procedurally generating a level from a designer-made mission. We use a generative grammar to transform a mission into a level in a mixed-initiative design setting. We provide two case studies, dungeon levels for a rogue-like game, and platformer levels for a metroidvania game. The generators differ in the way they use the mission to generate the space, but are created with the same tool for content generation based on model transformations. We discuss the differences between the two generation processes and compare it with a parameterized approach.

In L1 grammar teaching, teachers often struggle with the students’ conceptual understanding of the subject matter. Frequently, students do not acquire an in-depth understanding of grammar, and they seem generally incapable of reasoning about grammatical problems. Some scholars have argued that an in-depth understanding of grammar requires making connections between concepts from traditional grammar and underlying metaconcepts from linguistic theory. In the current study, we evaluate an intervention aiming to do this, following up on a previous study that found a significant effect for such an approach in university students of Dutch Language and Literature (d = 0.62). In the current study, 119 Dutch secondary school students’ grammatical reasonings (N=684) were evaluated by language teachers, teacher educators and linguists pre and post intervention using comparative judgement. Results indicate that the intervention significantly boosted the students’ ability to reason grammatically (d = 0.46), and that many students can reason based on linguistic metaconcepts. The study also shows that reasoning based on explicit underlying linguistic metaconcepts and on explicit concepts from traditional grammar is more favored by teachers and (educational) linguists than reasoning without explicit (meta)concepts. However, some students show signs of incomplete acquisition of the metaconcepts. The paper discusses explanations for this incomplete acquisition.

Sign languages have been recognized as indigenous to Europe by the key European institutions. The European Parliament has passed resolutions on sign languages on three occasions (1988, 1998, 2016a). The Council of Europe’s (CoE) Parliamentary Assembly supported a resolution on sign languages in 2003 (Council of Europe, 2005), and the European Centre for Modern Languages (ECML; an organization established under the auspices of the CoE) has supported work on sign language teaching, learning and assessment (Leeson, Van den Bogaerde, Rathmann, & Haug, 2016

When teaching grammar, one of the biggest challenges teachers face is how to make their students achieve conceptual understanding. Some scholars have argued that metaconcepts from theoretical linguistics should be used to pedagogically and conceptually enrich traditional L1 grammar teaching, generating more opportunities for conceptual understanding. However, no empirical evidence exists to support this theoretical position. The current study is the first to explore the role of linguistic metaconcepts in the grammatical reasoning of university students of Dutch Language and Literature. Its goal was to gain a better understanding of the characteristics of students’ grammatical conceptual knowledge and reasoning and to investigate whether students’ reasoning benefits from an intervention that related linguistic metaconcepts to concepts from traditional grammar. Results indicate, among other things, that using explicit linguistic metaconcepts and explicit concepts from traditional grammar is a powerful contributor to the quality of students’ grammatical reasoning. Moreover, the intervention significantly improved students’ use of linguistic metaconcepts.
