Exploring the Applicability of Simple Syntax Writing Practice for Learning Programming

When learning programming, students learn the syntax of a programming language, the semantics underlying the syntax, and practice applying the language in solving programming problems. Research has suggested that simply the syntax may be hard to learn. In this article, we study difficulty of learning the syntax of a programming language. We have constructed a tool that provides students code that they write character-by-character. When writing, the tool automatically highlights each character in code that is incorrectly typed, and through the highlight-based feedback directs students into writing correct syntax. We conducted a randomized controlled trial in an introductory programming course organized in Java. One half of the population had the tool in the course material immediately before programming exercises where the practiced syntax was used, while the other half of the course population did not have the tool, thus approaching the exercises in a traditional way. Our results imply that isolated syntax writing practice may not be a meaningful addition to the arsenal used for teaching programming, at least when the programming course utilizes a large set of small programming exercises. We encourage researchers to replicate our work in contexts where syntax seems to be an issue.Peer reviewe

Introductory programming: a systematic literature review

As computing becomes a mainstream discipline embedded in the school curriculum and acts as an enabler for an increasing range of academic disciplines in higher education, the literature on introductory programming is growing. Although there have been several reviews that focus on specific aspects of introductory programming, there has been no broad overview of the literature exploring recent trends across the breadth of introductory programming. This paper is the report of an ITiCSE working group that conducted a systematic review in order to gain an overview of the introductory programming literature. Partitioning the literature into papers addressing the student, teaching, the curriculum, and assessment, we explore trends, highlight advances in knowledge over the past 15 years, and indicate possible directions for future research
