Building Open Educational Resources from the Ground Up: South Africa's Free High School Science Texts

This paper presents a case study of the development of the South African project Free High School Science Texts (FHSST), an initiative to develop a free high school science text for all teachers and learners in South Africa. The goals of the case study were two-fold: to examine and analyze the practices associated with the successes and challenges encountered by FHSST; and to encourage a participatory, analytical process that will assist other open education projects in thinking about and sharing their practices, processes, and strategies. Beyond its implications for South African education, the FHSST project can serve as a model for peer production of open content, offering insights into planning and decision making around 1) recruiting volunteers; 2) sustaining their participation; 3) using technology to create effective workflow; 4) conducting hackathons; and 5) facilitating teacher trials. Findings from this study offers insights into overall approaches and goals that may prove instrumental across open education projects, serving as a reference for development of assessment tools and resources that may assist open education projects in tracking, sharing, and advancing their learnings and success

Analysis and Detection of Information Types of Open Source Software Issue Discussions

Most modern Issue Tracking Systems (ITSs) for open source software (OSS) projects allow users to add comments to issues. Over time, these comments accumulate into discussion threads embedded with rich information about the software project, which can potentially satisfy the diverse needs of OSS stakeholders. However, discovering and retrieving relevant information from the discussion threads is a challenging task, especially when the discussions are lengthy and the number of issues in ITSs are vast. In this paper, we address this challenge by identifying the information types presented in OSS issue discussions. Through qualitative content analysis of 15 complex issue threads across three projects hosted on GitHub, we uncovered 16 information types and created a labeled corpus containing 4656 sentences. Our investigation of supervised, automated classification techniques indicated that, when prior knowledge about the issue is available, Random Forest can effectively detect most sentence types using conversational features such as the sentence length and its position. When classifying sentences from new issues, Logistic Regression can yield satisfactory performance using textual features for certain information types, while falling short on others. Our work represents a nontrivial first step towards tools and techniques for identifying and obtaining the rich information recorded in the ITSs to support various software engineering activities and to satisfy the diverse needs of OSS stakeholders.Comment: 41st ACM/IEEE International Conference on Software Engineering (ICSE2019
