The purpose of this study was to conduct a content analysis of research on technology use for teaching mathematics to students with disabilities. We applied word networks and structural topic modeling of 488 studies published from 1980 to 2021. Results showed that the words "computer" and "computer-assisted instruction" had the highest degree of centrality in the 1980s and 1990s, and "learning disability" was another central word in the 2000s and 2010s. The associated word probability for 15 topics also represented technology use within different instructional practices, tools, and students with either high- or low-incidence disabilities. A piecewise linear regression with knots in 1990, 2000, and 2010 demonstrated decreasing trends for the topics of computer-assisted instruction, software, mathematics achievement, calculators, and testing. Despite some fluctuations in the prevalence in the 1980s, the support for visual materials, learning disabilities, robotics, self-monitoring tools, and word problem-solving instruction topics showed increasing trends, particularly after 1990. Some research topics, including apps and auditory support, have gradually increased in topic proportions since 1980. Topics including fraction instruction, visual-based technology, and instructional sequence have shown increasing prevalence since 2010; this increase was statistically significant for the instructional sequence topic over the past decade.

Background: Despite increasing awareness of the importance of promoting the social responsibility of science, technology, engineering, and mathematics (STEM) professionals, few intervention programs have been developed to enhance the social responsibility of college students or adults in the STEM fields. In this paper, we introduced a new instructional program, called ENACT (engage, navigate, anticipate, conduct, and take action) and examined whether the program increased the social responsibility among safety engineering students (N = 46) recruited from a university located in a southern metropolitan area of South Korea.

Results: In the ENACT program, the college students selected and explored socioscientific issues (SSIs) of their own interest then autonomously engaged in scientific and engineering group projects spanning a semester where they developed solutions to the SSIs and shared them with their communities. At the conclusion of the intervention in this study, they displayed an increased social responsibility regarding the consideration of societal needs and demands, civic engagement and services, and participation in policy decision-making. Social responsibility scores measured after the intervention (post-test) correlated with students' willingness to voluntarily participate in projects involving SSIs. In addition, the intervention effects were more pronounced for the students who initially had medium and low social responsibility scores.

Conclusions: We have shown that social responsibility can be nurtured by systemic instructional approaches, and increased social responsibility can lead to greater commitment to resolving SSIs. Mastering engineering content knowledge and skills is the key element of engineering curricula. However, we are compelled to incorporate social responsibility into the STEM curriculum. We believe that the ENACT model contributes toward this end.
