Within computer science education, many educators are incorporating software testing activities into regular programming assignments. Tools like JUnit and its relatives make software testing tasks much easier, bringing them into the realm of even introductory students. At the same time, many introductory programming courses are now including graphical interfaces as part of student assignments t...

since the emergence of the process-oriented approach to second language writing instruction two main questions have been what and how error feedback should be given to the students. the question of whether teachers should provide feedback on grammar in the writing assignments of english as a foreign language students, and if so how, has been a matter of considerable debate in the field of secon...

This study investigated the effects of blog-mediated instruction on English-as-a-foreign language (EFL) learners’ writing performance and anxiety. In addition, it aimed to probe into the EFL learners’ attitudes towards blog-mediated writing instruction. The participants of the study included forty-six Iranian EFL learners from two intact university classes, who were randomly assigned to the Con...

In the research of searchable encryption, fine-grained data authorization is a convenient way to manage search rights for users. Recently, Liu et al. proposed scheme with verification, which can control and verify results. this paper, we first present forgery attack against al.’s then propose novel verifiable in edge environment. Based on key aggregate mechanism Merkle hash tree, our not only a...

For a robust brain-computer interface (BCI) system based on motor imagery (MI), it should be able to tell when the subject is not concentrating on MI tasks (the "idle state") so that real MI tasks could be extracted accurately. Moreover, because of the diversity of idle state, detecting idle state without training samples is as important as classifying MI tasks. In this paper, we propose an alg...

OBJECTIVE While promising, electroencephaloraphy based brain-computer interfaces (BCIs) are barely used due to their lack of reliability: 15% to 30% of users are unable to control a BCI. Standard training protocols may be partly responsible as they do not satisfy recommendations from psychology. Our main objective was to determine in practice to what extent standard training protocols impact us...

The current study investigated the effectiveness of genre-based instruction on the development of EFL learners’ writing skills. Participants were 34 undergraduate students majoring in textile engineering at an Iranian state university, and they had enrolled in the English for specific academic purposes course. Participants were taught how to write 4 types of business letters, highlighting the p...

Brain-computer interface (BCI) has attracted great interests for its effectiveness in assisting disabled people. However, due to the poor BCI performance, this technique is still far from daily-life applications. One of critical issues confronting BCI research is how to enhance BCI performance. This study aimed at improving the motor imagery (MI) based BCI accuracy by integrating MI tasks with ...

Preliminary evidence suggests that handwriting difficulties are common to children with Attention Deficit Hyperactivity Disorder (ADHD). However, the nature of the task-specific impairments is needed to be clarified. The aim of this study was to describe handwriting capacity in ADHD children without DCD and identify underlying factors of performance by use of outcome-oriented assessments and a ...

Background: English language writing is important in university entrance examinations in Japan and influences what learners and teachers do in English classes. This is especially noticeable in secondary education in Japan. While much research on university entrance examinations in Japan has been conducted, little attention has been paid to the types of writing required in these examinations. Me...
