Project-based learning (PBL) is a teaching approach that has recently gained popularity. It allows students to develop real-world problem-solving skills by working on a project in a classroom setting over an extended period. In software engineering, project-based learning has become a common approach to teaching students how to develop high-quality software. However, there has been debate over the authenticity of these projects, with some arguing that it does not accurately reflect real-world software development challenges and complexities. In this post, we will analyze the authenticity of a course-based software engineering project and how it can be improved to better prepare students for the challenges of the software development industry.
Software engineering Lifecycle and ISTE
The International Society for Technology in Education (ISTE) contains a set of standards for students to use technology effectively for learning. The 4th ISTE standard for students is:
This standard highlights the importance of students using digital tools to manage projects, solve problems, and make informed decisions, as well as the ability to think critically and analyze risks in design, which are essential skills in modern software development.
The software development lifecycle embodies ISTE standard 4 for students, emphasizing the importance of producing high-quality software. The lifecycle comprises four primary stages: specification, design, implementation, and maintenance. The specification stage involves gathering and documenting the software requirements, while the design stage focuses on planning and structuring the software. The implementation stage is dedicated to developing and testing the software, and the maintenance stage involves monitoring and updating the software to ensure that it remains functional and usable over time. Each stage is an iterative process that produces partial outputs of the final deliverables.
Teaching the software engineering lifecycle in a classroom can present several challenges. One of the main issues is that software development is a highly dynamic process that is difficult to replicate in a classroom setting. Classroom projects may lack the same complexity or scope as real-world software projects, which can hinder students’ understanding of the software development lifecycle. Additionally, classroom environments may not provide students with the same level of exposure to real-world tools and technologies commonly used in software development (Kay et al., 2000). To address these challenges, the following project design outline is intended to enhance the effectiveness of a PBL software engineering project by integrating real-world elements.
Project Design
This project design methodology draws inspiration from the backwards design approach (Wiggins, 2005), and it has been compiled from three PBL projects by Shekar et al. (2014), Abad et al. (2019), and Spichkova et al. (2015) that were effectively carried out.
Through the project, students will understand the fundamental software lifecycle process and the reality of rapid changes in real-world requirements. They will also learn about the critical role of effective communication in ensuring customer satisfaction and the importance of maintaining quality standards throughout a software development project.
The software project aims to improve students’ hard and soft skills. Hard skills, which are measurable and specific, consist of software development skills in a particular language or framework, project planning, and written communication. In contrast, soft skills are personal attributes that enable students to collaborate effectively, such as teamwork, decision-making, communication, and organization.
To demonstrate a student’s understanding, the following evidence is required: appropriately documented changes made to the software at appropriate intervals, effective communication with the customer, including asking relevant questions, and the production of working software at the end of the development cycle that adheres to proper design and testing procedures.
Shekar et al. (2019) have proposed a set of assessments that should include the following elements:
- A project proposal that aims to replicate the initial phase of the software development lifecycle, including customer communication.
- A detailed design that specifies various alternatives and justifies the selection of the chosen design.
- A demonstration of the final product that establishes the student’s ability to effectively communicate their solution and exhibit a functional end product.
- The final project report that confirms that the software product was constructed according to the proposed design and testing procedures during the entire software development process.
- A self-reflection component that involves maintaining a journal that records successes, failures, and evaluations of team members.
Best Practices
Software Engineering educators encounter a significant challenge in balancing the provision of a realistic experience and maintaining classroom control when designing a project. The guidelines and best practices presented below are once again derived from successful project designs outlined in Shekar et al. (2014), Abad et al. (2019), and Spichkova et al. (2015).
- Provide real-world connections and real industry experience. Providing inadequate project specifications and forcing requirements to change can effectively challenge students and prepare them for real-world scenarios. A vagueness in the problem description from the client will force students to ask questions and shape their requirements-gathering workflow. Furthermore, a requirements change later in the process can force students to adapt and develop explicit change management skills (Abad et al. 2019).
- Include flexibility and team-oriented decision-making. In the approach by Abad et al. (2019), students can exercise flexibility in their development process by selecting from various software process models, including Opportunistic, Waterfall, Spiral, Concurrent, or Scrum, and justifying their choice of methodology for their system development. They can also modify their chosen process model as the project advances. Similarly, in Spichkova et al.’s (2015) approach, the design architecture incorporates a team-oriented decision-making component to encourage collaborative decision-making among team members.
- Focus on team dynamics. Effective teamwork is a critical factor in the success of a project. It is essential to clarify that everyone has an equal role and that all team members share ownership of the code base (Sepahkar et al., 2014). According to Bates (2022), another crucial aspect is establishing an interactive and asynchronous communication medium which all team members can access and utilize. Examples of such mediums include Facebook messenger, MS teams, and Discord. This fosters a collaborative environment where all team members are accountable to each other and can respond promptly to ensure the success of the project.
- Include personal reflections. Shekar et al. (2014) suggest incorporating personal reflection journals at each stage of the development process. This gives students a high-level view of the entire process and allows them to reflect on their progress. In the reflection journal, students should consider what went well during each stage, any unexpected difficulties they encountered, how to improve pacing, engagement, and assessments, and how to align each stage more closely with the primary objectives of the iteration.
Conclusion
Providing an authentic project-based learning experience in software engineering can be a challenging but rewarding experience for software engineering educators. By designing projects that simulate real-world scenarios, students can develop both technical and soft skills that are crucial for success in the software development industry. Moreover, incorporating assessment strategies that align with the software development lifecycle and emphasizing effective communication, collaboration, and self-reflection can enhance the learning experience for students. By following the guidelines and best practices proposed, educators can strike a balance between providing students with a realistic experience, maintaining classroom control, and preparing them for the challenges and opportunities in the software engineering industry.
