This paper reports on the results of 200 Group Suppor Systems (GSS) experiments that have been published between 1971 and June of 1998. 1582 hypotheses resulting from pairings of independent and dependent variables were categorized and analyzed. The results show that the modal outcome for GSS systems compared to face-to-face (FtF) methods is "no difference," while the overall percentage of posi...

With recent developments in communication and information technology there has been increasing research into the role and the impact of computer media in collaborative design. This paper presents a case study that compares two designers collaborating in three different types of virtual environments with face to face (FTF) collaboration. The aim of the study is to identify similarities and diffe...

The standard tool to estimate the phase of a sequence of phase-shifted interferograms is the Phase Shifting Algorithm (PSA). The performance of PSAs to a sequence of interferograms corrupted by non-white additive noise has not been reported before. In this paper we use the Frequency Transfer Function (FTF) of a PSA to generalize previous white additive noise analysis to non-white additive noisy...

Computer mediated communication (CMC) systems are providing new ways to communicate. Yet many text-based CMC systems do not represent the invisible, interactive practices, such as turnnegotiation, commonly found in face-to-face (FTF) conversations. Designing new text structures may help address these problems. To explore the effects of adding rhythmic, non-verbal cues to computermediated commun...

Evolutionary psychologists believe the human mind evolved to solve adaptive problems present in our ancestral environment. Our hominid ancestors survived in face-to-face groups by assessing the cooperative intentions of other group members. Media naturalness theory postulates face-to-face is the most ‘natural’ communication medium. This paper reports results from a laboratory experiment examini...

Due to the versatility as well as its ease of implementation, the Fast Transversal Filters algorithm is attractive for many adaptive filtering applications. However, it is not widely used because of its undesirable tendency to diverge when operating in finite precision arithmetic. To compensate, modifications to the algorithm have been introduced that are either occasional (performed when a pre...

This paper compares the processes of Face-To-Face (FTF) teams and Online Learning Teams (OLTs) and proposes methods to improve the performance of OLTs. An empirical study reviewed the performance of fifteen FTF teams and OLTs and their communication patterns were coded by the TEMPO system developed by Futoran et al. (1989) in order to develop a discourse analysis for each team. The results conf...

In this study, we explored the potential of enriching a wellworking individual writing-to-learn approach in a face-to-face setting and a net-mediated setting. Thirty-six undergraduate psychology students worked in dyads on a common learning protocol in each of these settings. Effects on the collaboration process and on strategy use in the learning protocols were assessed. Participants evaluated...

Abstract Background The Objective Structured Clinical Exam (OSCE) is a useful means of generating meaningful feedback. OSCE feedback may be in various forms (written, face to and audio or video recordings). Studies on are uncommon, especially involving Asian medical students. Methods We compared two methods delivered fourth year students Malaysia: (i) Face (FTF) immediate (semester one) (ii) In...

Objectives: This study examines how the transition to remote delivery during spring of 2020 affected student learning in basic communication course. Methods: Participants three different course modes (face-to-face, online, and live interactive) were enrolled a public speaking with standardized adaptive reading quizzes, exams, speech assignments. completed several measures over semester had thei...
