This article explores ways to assess interactional performance, and reports on the use of a test format that standardizes the interlocutor’s linguistic and interactional contributions to the exchange. It describes the construction and administration of six scripted speech tasks (instruction-, advice-, and sales tasks) with pre-vocational learners (n=34), and reports on the extent to which these tasks can be used to assess L2 speakers’ interactional performance in a reliable and valid manner. The high agreement found between three independent raters on both holistic- and analytical measurements of interactional performance, indicate that this construct can be measured reliably with these tasks. Means and standard deviations demonstrate that tasks differentiate between speakers’ interactional performance. Holistic ratings of linguistic accuracy and interactional ability correlate highly between tasks that focus on different language functions, and are situated in different interactional domains. Furthermore, positive correlations are found between both holistic and analytic ratings of oral performance and vocabulary size. Positive within-task correlations between analytical ratings of specific interactional strategies and holistic ratings of overall interactional ability show that analytic ratings of Meaning Negotiation and Correcting Misinterpretation provide additional information about speakers’ interactional ability that is not captured by holistic assessment alone. It is concluded that these tasks are a useful diagnostic tool for practitioners to support their learners’ interactional abilities at a sub-skill level.

Little is known about the effects of different instructional approaches on learner affect in oral interaction in the foreign language classroom. In a randomized experiment with Dutch pre-vocational learners (N = 147), we evaluated the effects of 3 newly developed instructional programs for English as a foreign language (EFL). These programs differed in instructional focus (form-focused vs. interaction strategies- oriented) and type of task (pre-scripted language tasks vs. information gap tasks). Multilevel analyses revealed that learners’ enjoyment of EFL oral interaction was not affected by instruction, that willingness to communicate (WTC) decreased over time, and that self-confidence was positively affected by combining information gap tasks with interactional strategies instruction. In addition, regression analyses revealed that development in learners’ WTC and enjoyment did not have predictive value for achievement in EFL oral interaction, but that development in self-confidence did explain achievement in EFL oral interaction in trained interactional contexts.

In het herstellen en behouden van zinvolle bezigheden voor mensen met een lichte of matige vorm van van de ziekte van Alzheimer is doelstelling van groot praktisch belang. De studies gericht op dit doel hebben vertrouwd op de verschillende strategieën van zelfmanagement van instruction cues. Zeven studies werden gevonden die plaats hadden in de periode 2008-2012 (dat wil zeggen, de periode waarin onderzoek op dit gebied daadwerkelijk vorm heeft gekregen). Die strategieën bestaan uit het gebruik van (1) verbale signalen aangeboden via audiorecorders, (2) visuele signalen aangeboden via computersystemen, en (3) een combinatie van verbale en visuele signalen gepresenteerd via computersystemen. Dit artikel geeft een overzicht van de hiervoor genoemde strategieën en bespreekt de resultaten daarvan, hun algemene doeltreffendheid, op prestaties en stemmingen, en hun geschiktheid en bruikbaarheid. Thema's voor toekomstig onderzoek werden eveneens onderzocht. ABSTRACT Helping people with mild or moderate Alzheimer's disease restore and maintain constructive occupations is an objective of great practical importance. Studies targeting this goal have relied on different strategies for self-management of instruction cues. Seven studies were identified in the period 2008- 2012 (i.e. the period in which research in this area has actually taken shape). These strategies consist of the use of (1) verbal cues presented via audio recording devices, (2) pictorial cues presented via computer-aided systems and (3) combinations of verbal and pictorial cues presented via computer-aided systems. This paper reviews these strategies and discusses their outcomes, their overall effectiveness on performance and mood, and their suitability and practicality. Issues for future research are also examined.

Little is known about the effect of diverging pedagogies on the development of interactional oral skills in a foreign language. In a controlled study, we evaluated three newly developed instructional programmes that were situated in the same training context, but that differed in instructional focus and type of task. These were compared to the effects of business-as-usual instruction. Multilevel analysis revealed that all experimental groups outperformed the ‘business-as-usual’ control group on oral interaction skills (N = 199), with similar results for the programmes. Positive effects were found on interaction skills for trained contexts of use only. No transfer was found to tasks in other contexts of use. We conclude that receiving contextualised oral interaction instruction is beneficial to the development of pre-vocational learners’ interaction skills.

Even learners with good language ability do not automatically engage in interactional encounters in the foreign language. Affective factors, such as speakers’ willingness to communicate (WTC), self-confidence and enjoyment of oral interaction play an important role in this (e.g. Dewaele & MacIntyre, 2014; MacIntyre, 2002). Little is known, however, about the effects of different instructional approaches on learner affect in oral interaction in the foreign language classroom. In a randomized experiment with Dutch pre-vocational learners (N = 147), we evaluated the effects of three newly developed instructional programmes for English as a foreign language (EFL). These programmes differed in instructional focus (form-focused vs interaction strategies-oriented) and type of task (pre-scripted language tasks vs information gap tasks). Multilevel repeated measures analyses revealed that learners’ enjoyment of EFL oral interaction was not affected by instruction, that WTC decreased over time, and that self-confidence was positively affected by combining information gap tasks with interactional strategies instruction. In addition, regression analyses revealed that development in learners’ WTC and enjoyment did not have predictive value for task achievement in EFL oral interaction, but that development in self-confidence did explain task achievement in trained interactional contexts. These results suggest that it is worthwhile for practitioners to address the development of self-confidence in their language lessons, and that they could do so my combining the use of information gap tasks with interactional strategy instruction that includes compensation-and meaning negotiation strategies.

This thesis explores the opportunities for developing and assessing learners’ EFL oral skills in pre-vocational classrooms in the Netherlands. The thesis contains four studies. First, we evaluate the oral interaction practice offered in EFL coursebooks. In the second study, we explore ways to assess individual ability in oral interaction in a reliable and valid manner. Studies three and four report on two experimental studies. Study three investigates the effects of instructional programs on learners’ interactional ability, and study four investigates the effects of these programmes on the affective measures willingness to communicate, enjoyment and self-confidence. Additionally, this study explores the relationship between these affective variables and task achievement in oral interaction tasks. The thesis furthermore contains a summary and discussion of the main outcomes, suggestions for future research and for educational practice.

Many students persistently misinterpret histograms. This calls for closer inspection of students’ strategies when interpreting histograms and case-value plots (which look similar but are diferent). Using students’ gaze data, we ask: How and how well do upper secondary pre-university school students estimate and compare arithmetic means of histograms and case-value plots? We designed four item types: two requiring mean estimation and two requiring means comparison. Analysis of gaze data of 50 students (15–19 years old) solving these items was triangulated with data from cued recall. We found five strategies. Two hypothesized most common strategies for estimating means were confirmed: a strategy associated with horizontal gazes and a strategy associated with vertical gazes. A third, new, count-and-compute strategy was found. Two more strategies emerged for comparing means that take specific features of the distribution into account. In about half of the histogram tasks, students used correct strategies. Surprisingly, when comparing two case-value plots, some students used distribution features that are only relevant for histograms, such as symmetry. As several incorrect strategies related to how and where the data and the distribution of these data are depicted in histograms, future interventions should aim at supporting students in understanding these concepts in histograms. A methodological advantage of eye-tracking data collection is that it reveals more details about students’ problem-solving processes than thinking-aloud protocols. We speculate that spatial gaze data can be re-used to substantiate ideas about the sensorimotor origin of learning mathematics.

Blended learning offers a learner-centred approach that employs both in-class learning and digital technology to facilitate online learning. Such an approach is especially advantageous to adult-learners in higher education as it meets their educational needs. However, adult-learners’ participation in blended learning programmes remains challenging due to a general lack of online interaction, and no clear teaching strategies that address this concern. Literature relating to adult-learners’ educational needs and online interaction was consulted in order to design teaching strategies that foster adult-learners’ online interaction. The aim of this study is to further validate these teaching strategies, hence a multiple case study was carried out using a mixed method approach. As such, eight teachers and sixteen students from four courses across three universities in Belgium and the Netherlands were interviewed. Additionally, a questionnaire testing a pre-defined set of variables was distributed to 84 students. The results lead to a set of validated teaching strategies that help teachers to further develop their professional skills and expertise. The teaching strategies can be grouped into three categories, namely 1) the teacher's online presence, 2) collaborative learning activities and preparatory learning activities, and 3) the distribution of learning content and learning activities across online and in-class learning. An elaborate set of validated teaching strategies is included. This study aids towards teacher professional development and adds evidence-based knowledge to teaching strategies and instructional frameworks for adult-learners in higher education.

Objectives: To investigate immediate changes in walking performance associated with three implicit motor learning strategies and to explore patient experiences of each strategy. Design: Participants were randomly allocated to one of three implicit motor learning strategies. Within-group comparisons of spatiotemporal parameters at baseline and post strategy were performed. Setting: Laboratory setting. Subjects: A total of 56 community-dwelling post-stroke individuals. Interventions: Implicit learning strategies were analogy instructions, environmental constraints and action observation. Different analogy instructions and environmental constraints were used to facilitate specific gait parameters. Within action observation, only videotaped gait was shown. Main measures: Spatiotemporal measures (speed, step length, step width, step height) were recorded using Vicon 3D motion analysis. Patient experiences were assessed by questionnaire. Results: At a group level, three of the four analogy instructions (n=19) led to small but significant changes in speed (d=0.088m/s), step height (affected side d=0.006m) and step width (d=–0.019m), and one environmental constraint (n=17) led to significant changes in step width (d=–0.040m). At an individual level, results showed wide variation in the magnitude of changes. Within action observation (n=20), no significant changes were found. Overall, participants found it easy to use the different strategies and experienced some changes in their walking performance. Conclusion: Analogy instructions and environmental constraints can lead to specific, immediate changes in the walking performance and were in general experienced as feasible by the participants. However, the response of an individual patient may vary quite considerably.

This paper describes some explorations on the concept of disassemblability as an important circularity indicator for products because of its severe impact on reuse value. Although usefulness of the concept for determining disassembly strategies and for improving circular product design clearly shows in earlier studies, the link with Industry 4.0 (I4.0)-related process innovation is still underexposed. For further technical development of the field of remanufacturing, research is needed on tools & training for operators, diagnostics, disassembly/repair instructions and forms of operator support. This includes the use of IoT and cobots in remanufacturing lines for automatic disassembly, sorting and recognition methods; providing guidance for operators and reduction of change-over times. A prototype for a disassembly work cell for a mobile phone has been developed together with researchers and students. This includes the removal of screws by means of a cobot using both vision & the available info in the product’s Bill-Of-Materials, the removal of covers, opening of snap fits and replacement of modules. This prototyping demonstrates that it is relatively easy to automate disassembly operations for an undamaged product, that has been designed with repairability in mind and for which product data and models are available. Process innovations like robotisation influence the disassemblability in a positive way, but current indicators like a Disassembly Index (DI) can’t reflect this properly. This study therefore concludes with suggestions for an evaluation of disassemblability by looking at the interaction between product, process and resources in a coherent way.
