Digital inclusion of people with intellectual disabilities is not commensurate with those without disabilities. Societal, political, financial, individual and interpersonal barriers help explain this disparity. Caregivers can act as both support and gatekeeper to internet access and use by adults with intellectual disabilities. This study investigated micro-level interpersonal factors influencing access and use of the internet by an adult with intellectual disabilities to explore the balance and interplay of power and support around the processes of digital inclusion and online risk taking. Taking a case study approach, perspectives of three key stakeholders were gathered via interviews: the person with intellectual disabilities, his mother and a paid support worker. Perspectives and experiences were contrasted using systemic functional linguistic analysis of discourse to explore the ways power and support were represented in the language of negotiated digital inclusion. Dynamics between the parent and person with intellectual disabilities and between the parent and paid staff clearly influenced processes of digital inclusion and were affected by varying priorities, positions and perceptions of power to allow, disallow and monitor access and use of the internet. These had the power to shape and drive internet access. Language choices by the person with intellectual disabilities showed that he was not fully aware of the risks involved in engaging with certain aspects of digital inclusion but how he spoke about the internet indicated some autonomy in technology use. Supporting the development of digital competence, confidence and resilience in people with learning disabilities should be combined with support to increase self-awareness regarding digital risk. Those supporting people with intellectual disabilities towards digital inclusion need additional guidance on how to do this effectively for the people they support.  相似文献

This paper presents Chinese heritage parents' perspectives on young children's use of technology as a tool for language and cultural learning. Growing up with Confucian heritage culture, some Chinese parents have particular cultural beliefs about learning that value effortful learning practices and the social context of learning. However, some Chinese parents believe technology is just a tool for entertainment and keeps children away from social interaction, which leads to their preference of print-based literacy practices at home. Four parents from different families whose children were between the ages of four to five participated in this study. These parents were interviewed about their experience and history of using technology and their thoughts about technology as a tool for language and cultural learning. Four narratives were constructed to describe parents' experiences, histories, opinions, cultural values and beliefs. Parents' perspectives were influenced by a variety of intertwined factors, including their own childhood language learning experiences, their histories of using technology, their cultural values and beliefs about learning, the purpose of technological experiences, and the quality of available technological resources. Pedagogical implications for using technology with children and communicating with parents are discussed.  相似文献

Binocular disparity provides one of the important depth cues within stereoscopic three-dimensional (3D) visualization technology. However, there is limited research on its effect on learning within a 3D augmented reality (AR) environment. This study evaluated the effect of binocular disparity on the acquisition of anatomical knowledge and perceived cognitive load in relation to visual-spatial abilities. In a double-center randomized controlled trial, first-year (bio)medical undergraduates studied lower extremity anatomy in an interactive 3D AR environment either with a stereoscopic 3D view (n = 32) or monoscopic 3D view (n = 34). Visual-spatial abilities were tested with a mental rotation test. Anatomical knowledge was assessed by a validated 30-item written test and 30-item specimen test. Cognitive load was measured by the NASA-TLX questionnaire. Students in the stereoscopic 3D and monoscopic 3D groups performed equally well in terms of percentage correct answers (written test: 47.9 ± 15.8 vs. 49.1 ± 18.3; P = 0.635; specimen test: 43.0 ± 17.9 vs. 46.3 ± 15.1; P = 0.429), and perceived cognitive load scores (6.2 ± 1.0 vs. 6.2 ± 1.3; P = 0.992). Regardless of intervention, visual-spatial abilities were positively associated with the specimen test scores (η2 = 0.13, P = 0.003), perceived representativeness of the anatomy test questions (P = 0.010) and subjective improvement in anatomy knowledge (P < 0.001). In conclusion, binocular disparity does not improve learning anatomy. Motion parallax should be considered as another important depth cue that contributes to depth perception during learning in a stereoscopic 3D AR environment.  相似文献

Advances in online geospatial technologies (GST) have expanded access to K-12 classrooms which has implications for the support teachers require to effectively integrate GSTs to promote learning. Previous studies have shown the impact of GST-integrated lessons on student engagement, spatial thinking skills, and/or content knowledge; however, most of these studies have been small in scope and scale and frequently focus on the affordances of the technology, without addressing the context of the implementation and student characteristics for whom GST is most impactful. We attempt to address some of these gaps. Our program scaled an effective GST-focused professional learning and development program to a national audience through a facilitator development model. This paper explores the student characteristics and lesson factors that resulted in student interest in science and technology and careers in those fields. After teaching a Geospatial Inquiry lesson created during a teacher workshop, teachers (n = 82) submitted the lessons and surveys on the implementation of Geospatial Inquiry lessons. The implementation surveys and lessons were scored for alignment to the principles of high-quality Geospatial Inquiry. Students (n = 1924) completed a post-lesson retrospective survey and indicated the extent to which their perceptions and attitudes toward science and technology changed because of the lesson. Results indicate that teacher GST performance is associated with increases in student outcomes. Students with previous exposure to science activities were more likely to have increased interest and excitement in science and careers in science but decreased interest in technology careers. Students who had previous exposure to technology activities had increased interest and excitement in technology and careers in technology but decreased interest in science careers. Geospatial Inquiry lessons also had a significant impact on students who are traditionally underrepresented in STEM fields. After participating in the lessons, students who identify as female reported higher engagement and interest in science and higher interest in science careers. Students who identified as Black or Hispanic also reported higher interest and excitement in science and technology, and students who identified as Black reported marginally higher interest in science careers.  相似文献
