Most existing autograders used for grading programming assignments are based on unit testing, which is tedious to implement for programs with graphical output and does not allow testing for other code aspects, such as programming style or structure. We present a novel autograding approach based on machine learning that can successfully check the…

All students studying Computer Science (CS) deserve to have their basic psychological need for belonging satisfied. In this dissertation, I present two studies of belonging among CS students at the University of Washington-Paul G. Allen School of Computer Science and Engineering. In the first study, my collaborators implemented a resubmission…

As Computer Science course enrollments have increased over recent years, instructors have turned to automated grading systems to help relieve the burden of processing student assignments. However, the available autograding solutions have generally lacked support for traditionally difficult-to-grade advanced topics courses. In this thesis, I…

A well-run introductory CS1 course is essential for all students within CS education. CS1 is necessary to keep students in the major and important to attract non-majors to the CS field. Unfortunately, there are many well-known issues that most CS1 courses have in common: high drop rates, low retention, high student stress, student struggle,…

The Purpose of this dissertation is to explore undergraduate Computer Science (CS) students' writing processes and transfer as they occur in the process of completing a writing assignment in a CS course. In particular, I observe and analyze students' writing processes, and investigate examples of writing knowledge transfer from prior and…

The problem of low student completion rates in distance learning courses remains one of the major issues that institutions of higher learning face. Efforts by school administrators to reverse this trend have so far produced mixed results. The rapid expansion of distance learning has encouraged many institutions to move more courses online,…

Effective software testing identifies potential bugs and helps correct them, producing more reliable and maintainable software. As software development processes have evolved, incremental testing techniques have grown in popularity, particularly with introduction of test-driven development (TDD). However, many programmers struggle to adopt TDD's…

Advances in technology and changes in educational strategies have resulted in the integration of technology into the classroom. Multimedia instructional tools (MMIT) have been identified as a way to provide student-centered active-learning instructional material to students. MMITs are common in introductory computer applications courses based on…

The educational system is changing to meet the needs of 21st century learners, technology integration has become critical in meeting that need. One-to-one computing may close the digital gap that exists and equips students with the skills necessary for success in the 21st century workplace (Lemke & Martin, 2004). While much research exists on…
