Research Brief

This academic research Investigated the learners’ outcome and its determinants via experiencing two different treatments.

First treatment by using traditional CMS and second treatment by using FB-based CMS.

A survey based on a developed hybrid eLearning success model is used to collect data.

Findings analyzed to assess the relations in the causal model and to compare the outcome constructs acquired via experiencing the two different systems.

5

Research Motivations

During the last five years; many researchers announced and recommend for further and future research to fill up two gaps:

6

Theoretical gap: The need for a

revised e-Learning system success model

Practical gap: The need for

more understanding of the FB effect

in learning outcome.

7

Theoretical gap: The need for a revised e-Learning system success model

• “A goal of continuing research would be an exploration of how the ISS model would be supplemented in order to more accurately reflect the E-learning environment”.

In 2010; Freeze, Alshare, Lane, & Wen state that

• Factors from the community of inquiry frameworks such as metacognitive, motivational, and behavioral traits of active online students may be a valuable add-on to the eLearning success model

In 2010; Shea & Bidjerano state that

• Considering the perspective of all players of the eLearning system and including additional different factors is important for a proper representation of the system success

In 2012; Bhuasiri et al. state that

• System success dimensions are not technology only, the revolution of web 2.0 and the uniqueness of eLeaning environment especially the different stakeholders guide the researchers to seek for new revised model

Cheng 2012; Lee et al. 2009; Chen 2010; Keramati et al. 2011; Sun et al. 2008; Hassanzadeh et al. 2012; Wang & Chiu 2011

8

Practical gap: The affect of using Facebook in learning outcome.

• Consolidating the Facebook in the learning and teaching process is very important for the students’ education lives and further research is needed to understand this phenomenon

In 2011; Bicen & Cavus

• Future research is needed to investigate more the usability of FB in education

In 2012; LaRue state that

• There is a need for understanding the relation between the learners’ interaction level in the Facebook and their academic success

In 2012; Junco stated that

• Considering the perspective of all players of the eLearning system and including additional different factors is important for a proper representation of the system success

In 2013; Ng & Wong stated that

Problem Statement:

Content Management System (CMS) is widely used in most of the universities worldwide to facilitate higher education stakeholders’ communications.

The challenge is whether Facebook environment “as a CMS system” is favorable and more effective than the traditional CMS system and what determinants/constructs affect the eLearning success.

Recently, few academic studies begin investigating this field of application. Further investigation is needed to fill up the illustrated gaps.

9

Research Objectives:To identify the dimensions of the information system success in the modern e-learning environment, and propose a modified model for e-learning system success.

To implement and test the proposed model when the implemented system is Moodle based.

To implement and test the proposed model when the implemented system is Facebook based.

To compare between the findings of the Moodle-based system analysis and the findings of the Facebook-based system analysis.

Research Design• The study starts up with a theory and ends up with testing

the hypothesis. Deductive Approach

• Statistical analysis based on descriptive measures, variance, covariance techniques are used.Quantitative

Research

• Literature review and systematic reviews techniques are used to build the hybrid model.Qualitative

Research

• This study aims to assess a desired field subjects in two different treatments then compare the outcomes. Field Experiment

Design

• “Counterbalanced Measures Design” technique is performed by assigning participants in different groups and applying treatments to each group in a different order.

Approach

Instrument Tool (Survey)

A questionnaire in English was derived for the study with two major sections.

The first section is for the demographics data, such as age, sex, gender, country, major study, and semester level.

The second section consists of 43 questions covered the independent, mediating and dependent constructs.

The five-point Likert scale with pre-coded numerical scales is used in order to measure the extent of respondent’s view.

22

Population and Sample

The population is

all the Module-

based Master students of LUCT ~ 362.

The minimum sample size

for SmartPls = 70.

the effective sample size

based on the statistical

power value = 153.

In reality, the analysed

sample = 231.

Experimental Design (Counterbalanced Measures Design)

This research is Semi-Experimental design use

AVE

Discriminant Validity (Fornell-Larcker Criterion Analysis)

“Correlation matrix of AVE values” scale used to show that measures outside a specific construct is not related to it.

Rule of thumb is that the square root of AVE value of a specific construct must be greater than all the other values in the same column or row of the correlation matrix

(Hair et al. 2014; Fornell & Larcker 1981).

Multicollinearity Analysis: (VIF) Variance Inflation Factor

Each set of exogenous latent variables in the inner model is checked for potential collinearity problem to see if any variables should be eliminated, merged into one, or simply have a higher-order latent variable developed.

The acceptable level of VIF value is above 0.20 and less than 5.00.

Significance of Construct Model Relations

Three values are used for the assessment that are significant level or probability estimate value (P value), the significance of path coefficient (T-statistics), and path coefficient.

As Hair (2014), the rule of thumbs for assessing the values is:

P-value could be on three levels 1%, 5% or 10%, but the popular level in psychological studies is 5% or (0.05).

With 5% significance level, T statistic > 1.96 is significant with a two-tailed test and T Statistics >.98 is significant for a one-tailed test.

Community of Inquiry Framework

87

Brief of COI

The community of inquiry framework is an instructional design model for eLearning developed by Randy Garrison, Terry Anderson et al. (2000).

This framework is for educational context as it proposes a framework for the use of computer-mediated communication to support the education process.

The framework has three essential elements cognitive presence, social presence, and teaching presence

88

The Community of Inquiry (CoI) bundle is the result of a project ran from 1997 to 2001.

Definitions of COI

Social presence refers to the ability of learners to project their personality into the community of inquiry, means learners can introduce themselves as a real people within the online communication or interaction.

Teaching presence construct outlines task sets such as organization, design, discourse facilitation, and direct instruction and articulates the specific behaviours likely to result in a productive community of inquiry.

Cognitive presence refers to the extent to which the participants in any particular configuration of a community of inquiry are able to construct meaning through sustained communication.

89

Preece’s Sociability and Usability Framework

90

Brief of Preece’s S&U

Preece (2000, 2001) proposed system usability and system sociability as determinants of the online community success. Goals, purposes and functions of the community affect the needs of online communities.

This framework used in many studies where the finding mostly shows a relationship between sociability and social benefits and usability and functional benefit.

91

Definitions of Preece’s S&U

Sociability dimension involves the measures related to the purpose, people, and policies. Purpose factor refers to the interaction and involvement levels of community participants.

Usability dimension covers the measures related to dialog and social interaction support, information design, navigation, and access.

Success definition of the online community differs based on the perspective of whom.

92

Delone and Mclean Information System Success Model

93

Brief of D&M IS Model

D&M IS success model is a result of attempts to provide an integrated scene of IS success that enables comparisons between different studies. It propose a broad and acceptable meaningful of the information system success.

The founders of this famous theory are William H. Delone and Ephraim R. McLean in 1992. Later on, the same authors revised the original theory and proposed an updated model after ten years in response to comments announced by other different researchers.

The updated model proposed six different dimensions of the IS success and provided an identifying, describing, and explaining the relationships among the six dimensions of success.

94

Definitions of D&M IS Model

System quality construct comprises the desirable characteristics of the system itself and includes related measures of the IS itself.

Information quality construct comprises the desirable characteristics of the information system output.

Service quality construct characterizes the quality of the support offered to system users by the IS department and IT support workforce.

The (intention to) use construct characterizes the user utilization level of the desired information system.

User satisfaction construct comprises the user’s level of satisfaction when using the desired information system.

Net benefits construct comprises the extent to which desired information system are contributing to the success of the desired users.95
