This study explores the development of multiple dimensions of linguistic complexity in the writing of beginning learners of German both as a group and as individuals. The data come from an annotated, longitudinal learner corpus. The development of lexicogrammatical complexity is explored at 2 intersections: (a) between cross‐sectional trendlines and the individual development paths of 2 focal learners and (b) between different complexity variables. The study contributes to the empirical body of linguistic complexity research by close tracking of beginning learners over 4 semesters of collegiate study of German as a second language (L2). For this purpose, data for multiple variables were collected at dense time intervals using multiple waves, and correlation analysis between various datasets was performed. The results confirm some general developmental trends established in previous research. However, the study also found significant variability between individual and cross‐sectional data. Furthermore, differences found for more specific complexity measures between this study's results and previous research are explained in terms of differences in instructional approaches. In addition, the study contributes to the discussion of methods and metrics appropriate for tracking the development of complexity in foreign language writing. The study concludes with implications for L2 pedagogy and further research, including applications of computational methods.

This study tracks the development of syntactic complexity in the writing of two beginning German as a second language learners with English as a first language over four semesters of collegiate language study by using developmental profiling techniques applied to an annotated learner corpus. The focus of the investigation is on individual developmental pathways and differences between learners who follow the same instructional sequences. The study explores variation in terms of frequencies of the selected complexity features (coordinate, nominal, and nonfinite verb structures) using corpus analysis techniques with semi-automatic corpus annotation. Two developmental profiles emerge from an in-depth contextual investigation of the target linguistic phenomena. The results show that the general developmental trend is for increasing frequency and range of syntactic complexity features with learners diverging more from one another in the second half of the observation period. This study addresses existing gaps in interlanguage complexity research by focusing on benchmarking development rather than gauging proficiency, addressing specific rather than global complexity measures, and targeting instructed learners at beginning rather than high-intermediate and advanced proficiency levels. Suggestions for future developmental second language acquisition research and foreign language pedagogy are made.

This article reports on a corpus-based, developmental pedagogical intervention for the teaching of German modal particles (MPs) in which learners examined their own emerging MP use as well as that of their native-speaking keypals in the context of electronically mediated, project-based collaboration. Individual learner development was traced micro-genetically over a period of nine weeks using Telekorp, a bilingual learner corpus with a built-in control corpus. The current study contributes to the teaching of second language (L2) pragmatics with respect to the authenticity of the interactions, the corpus-enabled nature of the intervention, the developmental scope of the data, and the potential for ‘hyper-noticing’ in Internet-mediated intercultural foreign language education.

Research on data-driven learning (DDL), or teaching and learning languages with the help of electronic corpora, has shown that it is both effective and efficient. Nevertheless, DDL is still far from common pedagogical practice, not least because the empirical research on it is still limited and narrowly focused. This study addresses some gaps in that research by exploring the effectiveness of DDL for teaching low-proficiency learners lexico-grammatical constructions (verb-preposition collocations) in German, a morphologically rich language. The study employed a pretest-posttest design with intact third- and fourth-semester classes for German as a foreign language at a US university. The same collocations were taught to each group during one class period, with one group at each course level taking a paper-based DDL lesson with concordance lines from a native-speaker corpus and the other one taking a traditional rule-based lesson with textbook exercises. These constructions were new to third-semester students, whereas fourth-semester students had been exposed to them in the previous semester. The results show that, whereas the DDL method and the traditional method were both effective and resulted in lexical and grammatical gains, DDL was more effective for teaching new collocations. The study thus argues in favor of using paper-based DDL in the classroom at lower proficiency levels and for languages other than English.

A B S T R A C TThis study explores ab initio development of syntactic complexity in a longitudinal corpus of learner German writing from a Dynamic Usage-Based perspective. It contributes to the research on L2 writing complexity by focusing on beginning learners of an L2 other than English (German) and on fine-grained measures of syntactic complexity, operationally defined here as syntactic modification.The results show that not only ubiquitous global measures of syntactic complexity but also more specific measures, namely frequencies of syntactic modifiers, can serve as developmental indices at beginning L2 proficiency levels. The learners in this study modified their writing from the very onset of language study and the overall size and range of the modification system did not significantly change over four semesters. However, its composition changed continuously and reflected non-linear waxing and waning of different modifier categories. The study confirmed some results from previous crosssectional research showing that interlanguage development is characterized by a decrease in cognitively easier (e.g., uninflected) categories and an increase in cognitively more difficult (e.g., inflected and clausal) categories. The high variability that was found along with uniform group trends demonstrates the necessity of simultaneous investigations of linguistic development in groups and individuals.
