This study aimed to analyse prospective physics teachers feedback during the implementation of online peer-assessment in Teaching Physics in English course. Twenty prospective physics teachers participated in this study. They were familiar with the use of smart phone in their daily life. They tend to communicate using social media such as WhatsApp application. The students have practiced in using paper based peer-assessment in other courses, but they have not applied it in online method providing real time feedback and score. The implementation of online peer-assessment challenged the students to assess their peer objectively. The lecturers feedback influence students skills how to evaluate their peer performance. Several factors may influence the quality of students online peer-assessment such as students culture back ground, implementation of the online peer-assessment, and practicants performance.

The study investigated the effects of anonymity on online peer assessment and compared three different conditions. Fifty-eight preservice teachers at a mid-size US university engaged in a series of online peer assessments during fall 2017. Peer assessment was embedded in a blended course as a required asynchronous activity using the Canvas learning management system. Students were randomly assigned to three different peer assessment conditions: anonymous, partially anonymous, and identifiable. They were asked to provide feedback comments and rate the quality of peers’ work. The researcher examined to what extent three different conditions had influenced the quality of feedback comments, measured quantitatively through the number of words and negative statements. At the end of the semester, a survey that included a 5-point Likert scale and several open-ended questions was also distributed to analyse students’ perceptions about peer assessment and anonymity. The results indicate that although students prefer anonymity, it may not be a necessary condition for increasing student engagement.

A 2´2 experiment was conducted to determine the effects of anonymity (anonymous vs. named) and peer-accountability (more-accountable vs. less-accountable) on peer over-marking, and on the criticality and quality of peer comments during online peer assessment. Thirty-six graduate students in a Web-based education research methods course were required to critique two published research articles as a part of their course. Peer assessment was carried out on the first critique. Students were randomly assigned to one of the four groups. Peer assessors were randomly assigned three students’ critiques to assess. Peer assessors and the students being assessed were from the same group. Peer assessors assigned a numeric mark and commented on students’ critiques. The four main results were: First, significantly fewer peer assessors over-marked (i.e., assigned a higher mark relative to the instructor) in the anonymous group as compared to the named group (p < .04). Second, peer assessors in the anonymous group provided a significantly higher number of critical comments (i.e., weaknesses) as compared to the named group (p < .01). Third, peer assessors in the named groupand the more-accountable group made a significantly higher number of quality comments (i.e., cognitive statements indicating strengths and weakness along with reasoned responses and suggestions for improvement), compared to the peer assessors in the anonymous group and the less-accountable group (p < .01). Lastly, the students’ responses to the questionnaire indicated that they found the peer assessment process helpful. This study suggests that in online peer assessment, the anonymity and the degree of peer-accountability affect peer marking and comments.

Detection Of Stress

Currently, mental stress is a major problem in our society. It is related to a wide variety of diseases and is mainly caused by daily-life factors. The use of mobile technology for healthcare purposes has dramatically increased during the last few years. In particular, for out-of-lab stress detection, a considerable number of biosignal-based methods and systems have been proposed. However, these approaches have not matured yet into applications that are reliable and useful enough to significantly improve people’s quality of life. Further research is needed. In this paper, we propose a portable system for real-time detection of stress based on multiple biosignals such as electroencephalography, electrocardiography, electromyography, and galvanic skin response. In order to validate our system, we conducted a study using a previously published and well-established methodology. In our study, ten subjects were stressed and then relaxed while their biosignals were simultaneously recorded with the portable system. The results show that our system can classify three levels of stress (stress, relax, and neutral) with a resolution of a few seconds and 86% accuracy. This suggests that the proposed system could have a relevant impact on people’s lives. It can be used to prevent stress episodes in many situations of everyday life such as work, school, and home.

The Media

From artists like Michelangelo to Andy Warhol, art has played an interesting role in conveying messages to society. Worldwide increase in media consumption and increasing time spent on the Internet make art previously concerning niche audiences more widespread. In December 2019, Art Basel, one of the most important art platforms in the world, came to such attention with artwork exhibited in one of its galleries. When Maurizio Cattelan's work titled “Comedian”, which consisted of a banana affixed to a wall with duct tape, was sold for $150,000, it came to the limelight through the media. It was then transformed into a simulation with the interest of marketers and communicators and took its place among real-time marketing examples. In this study, Cattelan's “Comedian” is analyzed in terms of similarly prepared and published Turkish social media advertisements inspired by the artwork. It was seen that simulations most associated with the artwork in terms of visual and meaning had most online interaction and even won awards. Jean Baudrillard’s perspective that a vast process of simulation is taking place over the span of daily life, similar in style to ‘simulation models’ through which operational and cybernetic sciences work, is discussed in this context. The evidence from this study suggests that ‘banana copycats’ are creating by combining features or elements of reality.

Authenticity and transparency constitute two essential dimensions in the digital assessment of competences. Authenticity emphasises the importance of the complexity inherent to online assessment tasks related to real life contexts and are recognised as relevant by students, teachers and potential employers. Transparency has to do with the students’ involvement in the assessment tasks, through the democratisation and knowledge of the used strategies. Self-, co- and peer assessment are powerful instruments in the transparency operationalisation. The current study presents the peer assessment (PA) implementation process in a first cycle university degree curricular unit, in online context. The study was planned according to the following purposes: (a) to identify peer assessment potentialities and constraints in first cycle university degrees; (b) to analyse the questions that are brought forward among students by the application of a scoring rubric; (c) to reflect on the obtained results, aiming at the improvement of the implementation process and its applicability to other curricular units. In this essay, the authors present and discuss the obtained results, and propose recommendations to improve the quality of the peer assessment process.

Quality Of Information

Social media have been central in informing people about the COVID-19 pandemic. They influence the ways in which information is perceived, communicated and shared online, especially with physical distancing measures in place. While these technologies have given people the opportunity to contribute to public discussions about COVID-19, the narratives disseminated on social media have also been characterised by uncertainty, disagreement, false and misleading advice. Global technology companies have responded to these concerns by introducing new content moderation policies based on the concept of harm to tackle the spread of misinformation and disinformation online. In this essay, we examine some of the key challenges in implementing these policies in real time and at scale, calling for more transparent and nuanced content moderation strategies to increase public trust and the quality of information about the pandemic consumed online.

Preparatory Work

Social media platforms such as Facebook have been understood to present new possibilities for interaction. Yet, there have been concerns surrounding the reducing quality of our interaction and conversation. Such debates, however, have not considered the pre-post dimension of online environments: that is, the preparatory work that occurs to online posts before they are shared with their audience. Based on real-time recordings of Facebook Messenger interactions, this article asks what the pre-post perspective tells us about the quality of our interactions online. The analysis is theoretically informed by Goffman and methodologically by conversation analysis and addresses this question with a specific focus on processes of identity construction and face. In presenting innovative screen capture data, this article argues against claims that our interaction online is declining in quality instead showing the ways users perfect their online posts by elaborating a new stage of online communication: the ‘rehearsal’ stage.
