The attempt to establish a common European framework for core platforms' duties and responsibilities toward other actors in the digital environment is at the core of the recent scholarly debate surrounding the Digital Markets Act (DMA) proposal. In particular, the everlasting juxtaposition between the “data power” – as emerging from recent cases (Section 2) – that dominant tech companies enjoy and the concept of consumer sovereignty (Section 3) lies at the core of the proposal's attempt to identify digital core platforms as market gatekeepers. Accordingly, this chapter critically investigates the divide between power imbalance and consumer sovereignty in light of the architecture designed by the DMA, with a specific focus on its effectiveness in identifying gatekeepers' power drivers (Section 4). After highlighting the main critical aspects of the pertinent rules, opportunities for fruitful developments are then identified through the reframing of some of the notions considered in the proposal, and namely the role of “lock-in” effects and “data accumulation” (Section 5). Lastly, this chapter suggests that the DMA advancements – while desirable – are bound to be fragmentary in the absence of a wider appraisal of the nature of data power imbalance dynamics in the modern digital markets (Section 6).

Purpose – To help teacher educators understand how to more fully prepare pre-service teachers (PSTs) for meaningful and effective instruction with multimodal texts and the underlying technologies.

Design – This mixed methods investigation employed designed-based research in that as the authors observed and gathered data on PSTs’ outcomes within the context of a literacy methods course, the authors also engaged in an iterative process of collaborative design to develop a sustainable instructional model across three academic semesters with three cohorts of PSTs. The authors analyzed pre- and post-PST surveys measuring their knowledge of, disposition toward, and self-efficacy with technology and technology in teaching as well their intent to use technology in their future teaching. The authors also coded and analyzed PST lesson plans completed across each semester for instances of meaningful integration of multimodal texts and the underlying technology, and sound literacy instruction. Finally, the authors closely examined differences in how the course was shaped and “reshaped” across all three iterations and noted any differences in PST outcomes related to these shifts.

Findings – Overall findings suggest that enrollment in the literacy methods course improved both PSTs’ self-efficacy and knowledge about teaching with technology while also supporting PSTs’ ability to develop sound literacy instructional plans. Moreover, strategic positioning of multimodal texts and technology, in which integration is seamless, can help PSTs meaningfully and effectively weave multimodal text sets into their literacy lesson plans.

Practical Implications – This chapter contributes to the literature on integrating multimodal texts and the underlying technologies into PST programs by providing explicit, research-based recommendations for how teacher educators can meaningfully and seamlessly infuse multimodal text sets into core curricula and instructional practices.
