Communication and Social Presence: The Impact on Adult Learners' Emotions in Distance Learning 
By Christina Angelaki and Ilias Mavroidis
Abstract
The aim of this work is to examine the
    role of communication and social presence in distance learning environments and
    their impact on the emotions of adult learners. A study was conducted at the
    Hellenic Open University (HOU), using a questionnaire that was completed by 94
    undergraduate and postgraduate students. More than 94 % of the students
    felt the need to communicate with their instructor and fellow students, but
    less actually did. More than 50 % of the students experienced both
    positive and negative emotions, while women were more prone to negative
    feelings. Negative emotions motivated students mainly to contact the tutor,
    while both negative and positive emotions motivated them to contact their
    fellow students. After communication, the majority of students felt positive
    emotions more intensely and negative ones less intensely, due to support and
    encouragement that they received from their tutor and fellow students. More
    than 80 % of the participants considered social presence as an important
    element of communication during their course, related to positive emotions.
    Regardless of the level of the course, age and marital status, quality
    student–tutor and student-student communication in the Hellenic Open University
    has an important effect on students’ emotional well being.

By Erica Smith, Ben Greatrex, Michelle Taylor and Ieva Stupans
Abstract
The study of chemistry is central within science and other associated degrees. At the University of New 
England in Armidale academics need to provide chemistry teaching in both
 a distance and the
    traditional on-campus mode within science and other degrees. This 
study explores the contribution that the adoption of Adobe
    Connect technology can make to support of students and enhancement 
of their
    learning. The preliminary response from students has been 
unequivocally
    positive with an increased confidence around unit materials gauged 
by improved
    student learning outcomes and unsolicited positive comments.
