The use of polytomous items in assessments has increased over the years, and as a result, the validity of these assessments has been a concern. Differential item functioning (DIF) and missing data are two factors that may adversely affect assessment validity. Both factors have been studied separately, but DIF and missing data are likely to occur…

One of the critical factors contributing to the effectiveness of human tutoring is the conversational aspect of the instruction. Our goal is to develop a general model for supporting dialogues with menu-based input that could be used in both well- and ill-defined instructional tasks. We have previously studied how human tutors provide additional…

Seemingly small situational problems with understanding and changes in the environment can constitute critical aspects in learning a task. I will describe and discuss through a detailed analysis of correction practices in interaction how learning in a situation influences a learner's ability to distinguish and handle continuity and change in…

The study looked at the effects of correction of learners' errors on learning of grammatical features. In particular, the manner of correction (explicit vs. implicit correction) was investigated. The study also focussed on the effectiveness of explicit and implicit correction of developmental early vs. developmental late features. Fifty-six…

This study intends to shed light on the most occurring grammatical and lexical (pragmatic) errors which students make in their compositions. For this purpose, 23 male and female undergraduate students from different majors were asked to take part in the present study. Each week, for four weeks, students were asked to write 4 compositions on…

To investigate the impact of self-correction method as an alternative to the traditional teacher-correction method, on the one side, and to evaluate the impact of personality traits of Extroversion/Introversion, on the other side, on the writing progress of the pre-intermediate learners three null-hypotheses were proposed. In spite of students…

Dynamic Assessment is a new theoretical framework for language assessment, and it is particularly relevant for underrepresented languages and learners. For this study the process is investigated in the context of Yugtun second language learners at a university level. This qualitative teacher action research was a study that involved seven…

Introduction: So far the role of grammar instruction and error correction has been mainly analyzed from the teachers' perspectives. However, learners' attitudes can also affect the effectiveness of any type of learning, especially language learning. Therefore, language learners' attitudes and beliefs should also be considered as a determining…

Surprise is of great value for learning, especially in cases where deep-seated preconceptions and assumptions are upset by vivid demonstrations. In this essay, Jonathan Adler explores the ways in which surprise positively affects us and serves as a valuable tool for motivating learning. Adler considers how students' attention is aroused and…

A postcompletion error (PCE) is a specific kind of cognitive slip that involves omitting a final task step after the main goal of the task is accomplished. It is notoriously difficult to provoke (and hence study) slips under experimental conditions. In this paper, the authors present an experimental task paradigm that has been shown to be…

English and German children aged 2 years 4 months and 4 years heard both novel and familiar verbs in sentences whose form was grammatical, but which mismatched the event they were watching (e.g., "The frog is pushing the lion", when the lion was actually the "agent" or "doer" of the pushing). These verbs were then elicited in new sentences. All…

In this paper I will show the preliminary findings from my study of the discourse in synchronous written chats performed by students who study modern German literature within their first term of German studies. The focus of the study is on learning strategies and discourse strategies and how the Swedish learners make use of them when chatting with…

Begun as an investigation of the linguistic and paleographic evidence on the Old Saxon Leipzig "Heliand" fragment, the dissertation encompasses three analyses spanning over a millennium of that manuscript's existence. First, a direct analysis clarifies errors in the published transcription (4.2). The corrections result from digital…

This study describes the effect of grades on second language writing performance. Do students write better when their essays are graded, and what implications might this have for foreign language instruction? This study compares three different types of student writing: graded compositions; for-credit online discussion boards; and ungraded,…

In this article, we provide an overview of School-wide Positive Behavior Support (SWPBS), an approach to building protective school cultures and preventing the development of problem behavior through instruction, environmental redesign, and attention to systems-level variables. We define the critical features of SWPBS within a prevention science…
