The impact of different teaching approaches and languages on student learning of introductory programming concepts

Many students experience difficulties learning to program. They find learning to program in the object-oriented paradigm particularly challenging. As a result, computing educators have tried a variety of instructional methods to assist beginning programmers. These include developing approaches geared specifically toward novices and experimenting with different introductory programming languages. However, having tried these different methods, computing educators are faced with yet another dilemma: how to tell if any of these interventions actually worked?The research presented here was motivated by an interest in improving practices in computer science education in general and improving my own practices as a computer science educator in particular. Its purpose was to develop an instrument to assess student learning of fundamental and object-oriented programming concepts, and to use that instrument to investigate the impact of different teaching approaches and languages on students’ ability to learn those concepts.Students enrolled in programming courses at two different universities in the Mid-Atlantic region during the 2009-2010 academic year participated in the study. Extensive data analysis showed that the assessment instrument performed well overall. Reliability estimates ranged from 0.65 to 0.79. The instrument is intrinsically valid since the questions are based on the core concepts of the Programming Fundamentals knowledge area defined by the 2008 ACM/IEEE curricular guidelines. Support for content validity includes: 71% of correct responses varied directly with the students’ scores; all possible responses were selected at least once; and 21 out of 24 questions discriminated well between high and low scoring students. CS faculty reviewers indicated that 19 out of 24 questions reflected basic concepts and should be used again “as is” or with “minor changes.” Factor analysis extracted three comprehensible components, “methods and functions,” “mathematical and logical expressions,” and “control structures,” suggesting the instrument is on its way to effectively representing the construct “understanding of fundamental programming concepts.”Statistical analysis revealed significant differences in student performance based on language of instruction. Analyses revealed differences with respect to overall score and questions involving assignment, mathematical and logical expressions, and codecompletion. Language of instruction did not appear to affect student performance on questions addressing object-oriented concepts.Ph.D., Information Science and Technology -- Drexel University, 201

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

Contemporary developments in teaching and learning introductory programming: Towards a research proposal

The teaching and learning of introductory programming in tertiary institutions is problematic. Failure rates are high and the inability of students to complete small programming tasks at the completion of introductory units is not unusual. The literature on teaching programming contains many examples of changes in teaching strategies and curricula that have been implemented in an effort to reduce failure rates. This paper analyses contemporary research into the area, and summarises developments in the teaching of introductory programming. It also focuses on areas for future research which will potentially lead to improvements in both the teaching and learning of introductory programming. A graphical representation of the issues from the literature that are covered in the document is provided in the introduction

Visual and Textual Programming Languages: A Systematic Review of the Literature

It is well documented, and has been the topic of much research, that Computer Science courses tend to have higher than average drop out rates at third level. This is a problem that needs to be addressed with urgency but also caution. The required number of Computer Science graduates is growing every year but the number of graduates is not meeting this demand and one way that this problem can be alleviated is to encourage students at an early age towards studying Computer Science courses. This paper presents a systematic literature review on the role of visual and textual programming languages when learning to program, particularly as a first programming language. The approach is systematic, in that a structured search of electronic resources has been conducted, and the results are presented and quantitatively analysed. This study will give insight into whether or not the current approaches to teaching young learners programming are viable, and examines what we can do to increase the interest and retention of these students as they progress through their education.Comment: 18 pages (including 2 bibliography pages), 3 figure

Emergent requirements for supporting introductory programming

The problems associated with learning and teaching first year University Computer Science (CS1) programming classes are summarized showing that various support tools and techniques have been developed and evaluated. From this review of applicable support the paper derives ten requirements that a support tool should have in order to improve CS1 student success rate with respect to learning and understanding

A review into the factors affecting declines in undergraduate Computer Science enrolments and approaches for solving this problem

There has been a noticeable drop in enrolments in Computer Science (CS) courses and interest in CS careers in recent years while demand for CS skills is increasing dramatically. Not only are such skills useful for CS jobs but for all forms of business and to some extent personal lives as Information Technology (IT) is becoming ubiquitous and essential for most aspects of modern life. Therefore it is essential to address this lack of interest and skills to not only fill the demand for CS employees but to provide students with the CS skills they need for modern life especially for improving their employability and skills for further study. This report looks at possible reasons for the lack of interest in CS and different approaches used to enhance CS education and improve the appeal of CS
