Two sets of opaque water-based acrylic coatings were prepared with IR-reflective pigments and conventional pigments. The objective of this work was to determine the efficiency of IR-reflective pigments in limiting the heat buildup of opaque coating formulations. Experiments performed on PVC substrates revealed that IR-reflective pigments significantly decreased the temperature increase above ro...

If students are demotivated, confused and look tired in class, one solution is to use new teaching styles in your class to overcome such problems. This is because learners learn in different ways such as hearing, seeing, taking notes, imagining and visualizing, among many others. The paper reports firstly, the impact of teaching and learning style preferences and their match or mismatch on lear...

Learning analytics for learners has the ability to greatly improve learners’ self-regulation. Current learner dashboards are mostly providing learners with an isolated view of their learning behavior, while we believe learners will gain more from a comparison of their own behavior with that of successful peer learners. In this work-in-progress demonstration we describe our design of a Learning ...

Self-determination theory (SDT) underpins research on learner empowerment, but it is rarely discussed in empowerment-related literature. In addition, a motivational measure stemming from SDT has received little visibility in communication research. To address these concerns, this study focuses on motivational theory and measurement in an attempt to tease out the relationship between motivation ...

In this paper we present a survey of some most significant spoken English learner corpora created up to date. Spoken learner corpora which include speech generated by learners are important in many areas of research and practice, in particular, for identifying typical pronunciation errors of learners of English as a second language (ESL), English as a foreign language (EFL), or English as a lin...

With the aim of storing learner corpora as well as information about the Basque language students who wrote the texts, two different but complementary databases were created: ERREUS and IRAKAZI. Linguistic and technical information (error description, error category, tools for detection/correction...) will be stored in ERREUS, while IRAKAZI will be filled in with psycholinguistic information (e...

In this paper we aim to describe the process by which our personalised web-based collaborative teaching/learning methodology (CECIP – Collaboration – Evaluation – Critical thinking – Individual assessment – learner Profile) evolved originating from Vygotsky’s theory and based on the (C) collaborative construction of student’s knowledge, (E) developing evaluation and assessment skills, (C) devel...
