Grammatical and discourse variation across educational blogs : A multidimentional analysis

This thesis critically addresses the Anglo centric bias and methodological fragmentation in digital discourse studies, particularly the neglect of professional digital genres in 'outer circle' English contexts. It aims to systematically identify, compare, and interpret the dominant linguistic dimensions characterizing British and Pakistani educational blogs. A rigorous dual-pronged Multidimensional Analysis (MDA) was employed on two purpose built corpora (BEBC and PEBC, 150 posts each). This involved a 'Classic MD' for external benchmarking and a 'New MD' with expanded features to uncover emergent, genre-specific dimensions. Meticulous data preprocessing, including validation of automated tagging, ensured data integrity. Factor analysis and ANOVAs revealed statistically significant cross cultural differences. Findings demonstrate educational blogging is not monolithic but profoundly shaped by distinct sociocultural priorities. The PEBC exhibits dimensions reflecting "Informational Density and Formal Argumentation," characterized by authoritative, objective, and syntactically elaborate prose, consistent with formal English prestige in Pakistan. Conversely, the BEBC is defined by "Elaborative Temporal and Descriptive Discourse," foregrounding personal narratives, subjective reflection, and direct engagement, aligning with Western pedagogical traditions valuing authenticity. This study makes significant contributions by providing a robust, dual-layered MDA framework for novel digital genres and offering empirical evidence for genre hybridity and 'glocalization,' thereby challenging simplistic formal-informal binaries. Critically, it serves as a decolonizing intervention in World English scholarship, quantitatively proving the systematicity of an 'outer circle' variety and fostering a pluri centric understanding of global English. Practically, insights are provided for intercultural professional communication, evidence-based digital literacy pedagogy, and genre-specific assessment. Delimitations regarding corpus representativeness and interpretive aspects are transparently acknowledged.
