KORIŠTENJE VIDEO KONFERENCIJE ZA POBOLJŠANJE STUDENTSKE KOLABORACIJE

Video conferencing has been present on software markets for decades. Yet, due to various technical and pedagogical restrictions, it has been relatively rarely used in online education. Following the advent of reliable and high-bandwidth internet protocol connectivity, as well as development of new videoconferencing system, potentials of synchronous computer supported collaborative learning through video conferencing have increased [1] [2]. In ancient Greece, those who weren’t interested to participate in public affairs were called “idiot”, so it may be said that there are a lot of idiots in a world today and the only one who can change things are educational institutions. By supporting synchronous collaborative learning, contemporary education has better chance to develop public citizen and not private individual or “idiot”. To facilitate such synchronous communication between students and teachers, not as a tool for teacher domination but as a tool for authentic education [3], this study looks into recent applications of the BigBlueButton (BBB) videoconferencing system integrated in open-source virtual learning environment, Moodle. In the capacity of learning technologist, author of this paper has been involved in various aspects of this application from software development, through support to teachers and students, to pedagogy. The paper analyse the main motivators for the implementing synchronous computer supported collaborative learning at the University of Applied Sciences. It briefly introduces the main technical issues in the application of Moodle/BigBlueButton, and explores its pedagogical applications in providing a suitable online environment for democratic education and encouragement of students to become “critical agents who actively question and negotiate the relationships between theory and practice, critical analysis and common sense and learning and social change” [4].Videokonferencijski sustavi već su desetljećima prisutni na tržištu. Međutim, zbog različitih tehničkih i pedagoških ograničenja, relativno su se rijetko koristili u online obrazovanju. Pojavom pouzdanog i širokopojasnog pristupa internetu, kao i razvojem novih videokonferencijskih sustava, potencijali sinkronog računalno potpomognutog kolaborativnog učenja (eng. Computer Supported Collaboratice Learning - CSCL) su značajno porasli [1] [2]. U staroj Grčkoj, one koji su imali pravo, a nisu bili zainteresirani za sudjelovanje u javnim poslovima, nazivali su “idiotima”, tako da se može reći da danas na svijetu ima puno “idiota”, a obrazovne institucije su jedine koje mogu promjeniti stvari. Podržavajući sinkrono kolaborativno učenje, suvremeno obrazovanje ima veće šanse da razvije javne građane, a ne privatne osobe ili “idiote”. Da bi se olakšala takva vrsta komunikacije između učenika i nastavnika, ne kao sredstvo za dominaciju nastavnika, već kao alat za autentično obrazovanje [3], u radu se gleda na primjenu BigBlueButton (BBB) videokonferencijskog sustava integriranog u open-source virtualno okruženje Moodle. U radu se analiziraju glavni poticatelji za provedbom sinkronog CSCL, te se ukratko uvodi u tehničke probleme u primjeni Moodle/BigBlueButton i istražuje njegove pedagoške primjene za pružanje odgovarajućeg mrežnog okruženja za demokratsko obrazovanje i poticanje studenata da promiču dijalog, raspravu i argumente potkrijepljene dokazima, te aktivno pregovaraju odnose između teorije i prakse [4]

Strategic Competencies of Prospective Teacher Students Based on Cognitive Style and Gender

This study aims to describe the strategic competencies of prospective teacher students based on cognitive style and gender in formulating, representing and solving problems. This type of research was descriptive qualitative. The supporting instruments were the GEFT (Group Embedded Figure Test) and the task of mathematical non routine problem contained several mathematical concepts, namely circles, trigonometry, and triangles. The research subjects consisted of 2 males Field Independent (FI) and 2 females Field Independent (FI), 6 females Field Dependent (FD) and 4 males Field Dependent (FD). Data was collected through documentation of solving mathematical problem and interview results. The data validity method used method triangulation and referencial adequacy checks. Research datas were analyzed by reducing data, presenting data and drawing conclusions. The results showed that  FI females and males  were more analytical than FD females and males. FI males and FI females both understood problem situations by drawing, but FI males recognized the circle concept more quickly and confidently than FI females. FI females were more analytical in the process of transferring problem situations into pictures than FI males. FI males and FI females both represented problem situations in pictures and symbols but FI females tended to have more logical pictures and symbols than FI males. FD females tended to understand problem situations by drawing more than FD males, therefore FD females were said to be more analytical in transferring problem situations into pictures compared to FD males. The four types of subjects did not arrive at a correct final solution

Exploring the Roles of Social Participation in Mobile Social Media Learning: A Social Network Analysis

Social media is increasingly becoming an essential platform for social connectivity in our daily lives. The availability of mobile technology has further fueled its importance – making it a ubiquitous tool for social interaction. However, limited studies have been conducted to investigate roles of social participation in this field. Thus, the study investigates roles of social participation in mobile social media learning using the “ladder of participation and mastering.” Participants were students taking an educational technology course in a local university. The study was conducted in a four-month period. Data was collected from discussions while learning among the students a social media platform, Facebook groups, on mobile devices. The data was analyzed using a social network analysis tool, NodeXL. Data was analyzed based on egocentric networks, betweeness centrality, and closeness centrality. The findings revealed that there are four roles of social participation in mobile social media, which are: (i) lurkers; (ii) gradually mastering members/passive members; (iii) recognized members; and (iv) coaches. The findings also indicated that over the course of four months, learners can inter-change roles of social participation – becoming more central or less central in learning discussions. As a result, a roles of social participation continuum for mobile social media learning is proposed. Future research could be conducted in other fields to investigate whether the continuum produced could be used to understand the relationship between mobile social media learning and social participation roles

Accommodating Students Different Learning Styles with the Use of Technology

The understanding of different learning styles is crucial for student academic success. The area of concentration pertaining to this topic includes the cognitive development during the adolescent age group selected. To create a good academic foundation, the teacher must exhibit different forms of learning styles to the students to create awareness and a good academic foundation. With the mass inclusion of technology in our society and education system, this research will attempt to understand the positive and negative effects of technology on effecting the students’ ability to use their effective learning style. Through the use of literature reviews and interviews with three teachers, this senior capstone examines the availability and access to technology and the effects of incorporating technology in the classroom to accommodate the students’ different learning styles

Cognitive apprenticeship in vocational students mathematical decision making skills

Exploring the decision-making abilities of undergraduate students, including students from vocational education backgrounds, is the main priority in the achievement of mathematics learning in general and in Calculus courses particularly. Decision-making processes require cognitive guidance through activities describing in detail the systematic steps of each process. It is implicitly said as part of a cognitive apprenticeship procedure. There are claims that students with a vocational education background can develop their academic and practical potential more through a cognitive apprenticeship model. In addition, using video as visual media learning allows students to sharpen their skills. Therefore, the study aims to explore the distinction in achievement and improvement of mathematical decision-making skills between undergraduate students who learn with a Video-assisted Cognitive Apprenticeship approach (CAV), and they are who receive Cognitive Apprenticeship learning (CA) with conventional learning. A quantitative study with the Static-Group Pretest-Posttest Design was employed as a methodology in the research. Based on the research stage, there are differences in achievement and improvement of student decision-making skills with a review of the type of vocational school between undergraduate students

The Effectiveness of an Accelerated Cohort Program on Grade Point Averages in the Industrial Process Control Technology Program at a Rural Middle Tennessee Community College

The purpose of this causal comparative study was to determine the effectiveness of accelerated cohort technical programs on student success, defined by grade point average, for both traditional and adult learners compared to traditional technical programs at the community college level. The study was conducted within the Industrial Process Control Program (IPCT) at a community college satellite campus located in a predominately rural county in middle Tennessee. The sample included 138 students who had successfully completed all remediation requirements and a minimum of one first semester IPCT course between the years of 2011 and 2014. Archival data was collected through cooperation with the community college\u27s Institutional Research Department. The research was conducted utilizing a 2X2 factorial design with testing for significance achieved through the use of a two-way ANOVA with an alpha level of .05. The study found no significant effect or interaction when considering the grade point averages of students regardless of delivery method or age. The study concluded that accelerated cohort programs are a viable alternative to traditional delivery methods. The researcher suggests that further study is needed on multi-site programs and accelerated cohort student motivation
