• OECD AI System Classification Framework as an analytical lens for comparing AI regulations - The OECD framework is a multifaceted classification approach for characterizing AI systems across technical, ethical, and societal dimensions.
• Onto-Epistemic Heterogeneity - Onto-epistemic heterogeneity holds that learners' diverse ways of being (ontology) and ways of knowing (epistemology) are interconnected resources that should be treated as constitutive of disciplinar
• Onto-Semiotic Approach (OSA) framework for analyzing mathematical knowledge and instruction - The OSA addresses epistemological, ontological and semiotic-cognitive problems in mathematics teaching by proposing a system of theoretical notions and methodological tools.
• Ontological Alignment - Coordinating between students' existing ideas and the representational system of a computational modeling tool — treating a tool's structure (what it makes visible and manipulable) as something a teac
• OpenSciEd practitioner needs maps: a conjecture-map-style framework linking seven support themes to three broad outcomes - The report organizes practitioner-identified needs into maps showing relationships and dependencies among needs, grouped into seven themes: professional learning, teacher agency/collaboration/manageme
• Opportunity-centered teaching framework adapted as four opposing equity mindset dimensions - The article draws on Milner's opportunity-centered teaching framework, rooted in critical race theory and culturally responsive and sustaining teaching, which posits that schools fail diverse students
• OptimNN: neural-network parameter generation (hypernetwork) for optimizing BKT - OptimNN replaces random initialization and direct SGD training of BKT's four per-skill parameters with a feedforward "parameter generation network" f that maps a skill ID to the four BKT parameters, s
• Options framework for addressing co-teaching in value-added models - The article organizes the policy problem of co-teaching in value-added models as a set of options available to policymakers, building on earlier work that described the Full Roster Method.
• Original charter school design rationale: alternative public schools enabling experimentation and innovation within the public school system - The publication describes the founding conception of charter schools as publicly funded but deliberately different institutions.
• OSP's two pedagogical approaches: guided inquiry and constructionism - The article states that the two main pedagogical approaches used in OSP are guided inquiry and constructionism.
• Outcome-domain organization of social and character development measures - The evaluation organizes its many measures into outcome domains, a grouping device for reporting effects across instruments and reporters.
• Output-driven, input-enabled hypothesis: output as both driving force and objective of EFL teaching - A tentative theory of foreign language teaching for tertiary-level students, proposed by Wen (2013, 2014, 2015), which “places emphasis on the importance of language output, or specifically teaching s
• Oxford's (1990) language learning strategy model with six strategy categories - The study's conceptual framework is Oxford's (1990) LLS model, chosen "due to its thorough categorization of LLSs and for its frequent mention and use in the literature." The model divides LLSs into s
