A teacher supervising the school practice of student teachers is regarded as an expert who sets an example of good teaching to future teachers and chooses teaching practices that support pupils’ co...
Teacher Guidance in Mathematical Problem-Solving Lessons: Insights from Two Professional Development Programs
2019
When implementing a problem-solving lesson, the teacher needs to provide students appropriate guidance during problem solving. This demanding task requires understanding students’ work in progress and giving them necessary help without constraining their thinking. In this article, we share insights from two professional development programs on how teachers guided students’ problem solving and how they reflected on these instances. One of the programs included Finnish pre-service teachers, while the other program included US in-service teachers. We analyzed video-recorded problem-solving lessons from 16 Finnish and 2 US teachers in grades 6–9. We found two themes about teacher guidance of st…
Eye-tracking revision processes of translation students and professional translators
2019
Great effort has been made to define and to measure revision competence in translation. However, combined eye tracking and keylogging have hardly been applied in revision research. We believe it is...
What are and what aren’t complex nominal expressions in flexible word order languages
2020
AbstractThis paper tackles the challenge of how to identify multi-word (or “complex”) nominal expressions in flexible word order languages including certain Australian languages and Vedic Sanskrit. In these languages, a weak or absent noun/adjective distinction in conjunction with flexible word order make it often hard to distinguish between complex nominal expressions, on the one hand, and cases where the nominals in question form independent expressions, on the other hand. Based on a discourse-based understanding of what it means to form a nominal expression, this paper surveys various cases where we arenotdealing with multi-word nominal expressions. This involves, in particular, peripher…
Assessment of learning strategies with the ACRA and the Brief-ACRA scales: Competitive models, measurement invariance, and prediction of academic ach…
2021
Abstract Learning strategies have been widely studied, and they have been related to academic achievement in several studies. Among the measurement instruments developed, the 44-item version of the Learning Strategies Scale (ACRA) is, by far, one of the most widely used questionnaires in the Spanish speaking context. This instrument has been recently shortened to a 17-item version. Neither the 44-item nor the 17-item version have been tested in the Dominican Republic. The aim of this study is to study the psychometric properties of the 44-item and 17-item versions of the ACRA. Participants were 1712 Dominican secondary school students. Both structures of the ACRA were tested via CFA; alpha …
Let's Talk Biology – Developing a Model for Incorporating English-Speaking Experts into the (Bilingual) Science Classroom
2019
We present an instructional approach to incorporate into biology lessons an exchange of videos between international practicing scientists and secondary-school students. We validated the approach in German school settings in three curricular contexts: genetics, cell biology, and immunology. The participating students (n = 255) were native speakers of German with a background of English as a foreign language. The three participating scientists, English-speaking experts from the United Kingdom and Uganda, were rooted in different fields that were related to the respective curricular topics. We explain how the video exchange model was developed and evaluate students' comments and suggestions f…
Selves, interactive representations and context
2021
Abstract In this paper, I re-examine the notion of ‘clause-as-representation’ in Michael Halliday’s systemic functional theory of language. I argue that ‘representation’ is a mode of linguistic action that cannot be understood in terms of the experiential metafunction alone. Instead, a theoretical account of representation must be undertaken in relation to all the metafunctions. Rejecting encodingist accounts of representation, I develop the argument that representations are interactively constituted and emergent in languaging activity. The paper develops these arguments in relation to a process ontological account of the relations between language and the world-side phenomena that language…
An Efficient Cooperative Smearing Technique for Degraded Historical Documents Images Segmentation
2020
Segmentation is one of the critical steps in historical document image analysis systems that determines the quality of the search, understanding, recognition and interpretation processes. It allows isolating the objects to be considered and separating the regions of interest (paragraphs, lines, words and characters) from other entities (figures, graphs, tables, etc.). This stage follows the thresholding, which aims to improve the quality of the document and to extract its background from its foreground, also for detecting and correcting the skew that leads to redress the document. Here, a hybrid method is proposed in order to locate words and characters in both handwritten and printed docu…
Engagement in Emergency Remote Education
2022
Digital storytelling (DST) has been effective for student engagement in second language (L2) education. Yet, its impact on engagement has commonly been examined in the classroom through synchronous DST tools and platforms. This study enquires whether DST can be equally engaging in the context of emergency remote education caused by the COVID-19 pandemic. The participants of the study are 42 student-teachers of English who developed an asynchronous online DST project. Data were collected through a DST questionnaire and were analysed using quantitative and qualitative data analysis methods. DST was found to generate mainly cognitive engagement through self-reflection processes and behavioural…
Foreign Language learning and teaching Enjoyment: Teachers’ Perspectives
2019
Aim. The primary objective of the present study was to investigate the level of Foreign Language learning Enjoyment and Foreign Language teaching Enjoyment experienced by foreign language teachers in Poland. The secondary aim of the study was to investigate the sources of FLE from the perspective of FL teachers.
 Methods. The informants of the study were Polish educators teaching foreign languages at different educational levels (from primary to tertiary education). To compute the obtained quantitative data, the statistical program STATISTICA was used. Standard descriptive and inferential statistics were used to report means, median and standard deviation for sociodemographic and base…
