Constructed response items can both measure the coherence of student ideas and serve as reflective experiences to strengthen instruction. We report on new automated scoring technologies that can reduce the cost and complexity of scoring constructed-response items. This study explored the accuracy of c-rater-ML, an automated scoring engine…

For decades, direction finding has been an important research topic in many applications such as radar, location services, and medical diagnosis for treatment. For those kinds of applications, the precision of location estimation plays an important role, since that, having a higher precision location estimate method is always desirable. Although…

Skill prerequisite information is useful for tutoring systems that assess student knowledge or that provide remediation. These systems often encode prerequisites as graphs designed by subject matter experts in a costly and time-consuming process. In this paper, we introduce "Combined student Modeling and prerequisite Discovery"…

The incorporation of prerequisite skill structures into educational systems helps to identify the order in which concepts should be presented to students to optimize student achievement. Many skills have a causal relationship in which one skill must be presented before another, indicating a strong skill relationship. Knowing this relationship can…

For corrective feedback (CF) to contribute to second language (L2) development, some cognitive processes need to be completed. Learners need to notice and comprehend the CF, reflect on and deeply process it, and finally integrate it into their interlanguage (Gass, 1997). Written languaging (WL), which requires learners to explicitly explain to…

This study aimed to investigate the effects of the integration of indirect feedback and concordances on improving grammatical accuracy in Thai EFL undergraduate students' writing and to explore the students' perceptions toward the intervention. Thirty third-year undergraduate students who studied at a government university in Bangkok were the…

Although several studies have investigated the self-assessment (SA) of writing skills, most research has adopted a cross-sectional research design. Consequently, our knowledge about the longitudinal development of SA is limited. This study investigated whether SA instruction leads to improvement in SA accuracy and in second language (L2) writing.…

Many empirical findings of previous studies have suggested a connection between motivational factors and L2 writing. Nonetheless, the impact of motivational factors on the genre-based L2 writing has not gained much attention. The present study explored the extent to which the characteristics of two writing tasks involving different genres interact…

Non-native phoneme perception can be challenging for adult learners. This article explores two routes to strengthening early representations of non-native targets: perceptual training, which focuses on auditory discrimination of novel contrasts, and articulatory training, which highlights the articulatory gestures of non-native categories. Of…

Over the last two decades, there has been an increasing interest in third language (L3) phonology (Cabrelli Amaro, 2012; Cabrelli Amaro & Wrembel, 2016). However, research so far has been primarily directed at specific stages of learning and has independently explored either production (e.g., Llama, Cardoso, & Collins, 2010; Llama &…

It is unknown whether and to what extent cognitive individual differences may play different roles in paper versus computer-based second language (L2) writing. This exploratory study is a first attempt to explore this issue, focusing on the effects of working memory and language aptitude on the quality of paper versus computer-based L2 writing…

Engaging students in the creation of learning resources is an effective way of developing a repository of revision items. However, a selection process is needed to separate high- from low-quality resources as some of the materials created by students can be ineffective, inappropriate or incorrect. In this study, we share our experiences and…

This study investigates the impact on L2 oral performance of participatory structure of strategic planning (individual vs. collaborative pair planning) and task complexity (simple vs. complex tasks) defined according to the number of elements involved. It also explores individual and collaborative planners' planning behaviours prior to simple vs.…

Taken together, the Coherence Principle of Multimedia Learning Theory and the Integrated Systems Hypothesis propose that co-occurring and semantically congruent verbal and visual information should be integrated into one mental representation that enhances memory. The purpose of this paper was to examine how learning pseudowords with matching…

Experimental research on the interface between second language vocabulary knowledge, including collocations, and translation competence is scarce. The present study investigates the role played by three determinants of collocation knowledge (knowledge level -- recall versus recognition, congruency, and constituent word types) in the accuracy of…
