Introduction
“Where is the knowledge we have lost in information?” Eliot (1963)
The computing ‘garbage in, garbage out’ mantra succinctly
express this problem. Which leads to the difficulty of identifying the
‘quality’ information that helps in increasing the user knowledge,
from a bulk of information (Stvilia et al., 2008).
In educational perspective, quality is a critical issue in general, and
more sensitive for Open Educational Resources (OER) (Alkhattabi et
al., 2011) due to the demand of high quality learning content and it needs to be measure through multidimensional criteria (Aladwania
et al., 2002; Alkhattabi et al., 2010).

College and universities are rapidly adopting eLearning platforms
and OER resources for their course delivery and training (Lim et al.,
2006), (e.g. (WOU), (SPeCTRUM), (OLIVE), MIT Open Courseware.
OER resources are facilitated by the use of new multimedia
technologies and the Internet to improve the quality of learning
(Commission of the European Communities, 2001).
This study is concerned about the OER content quality, in terms of knowledge gained from the content available on OER.
users’ concern is about the quality knowledge gain from the
available content in OER 7/14/2014

Problem Statement
Information quality of online content is discussed (Alkhattabi et al., 2011; Masoumi et al., 2012). However, area of ‘Quality’ research,
has been hampered by the lack of consensus on quality of
knowledge in OER.
knowledge quality is a vaguely defined concept. In literature,
researchers (Chiu et al, 2006; Halawi et al., 2008; Jennex et al., 2006;
Liu et al., 2010) used the Data quality (DQ) information quality
(IQ)dimensions to measure the knowledge quality (KQ), which is unjustifiable. Measurement of KQ is the key identified issue of this
study.
Lack of research discuss the KQ considering theory of knowledge
(Artemov et al, 2005; Lehrer, 1990; Lehrer et al., 1969) and
knowledge hierarchy (Braganza, 2004; Brodie et al., 2009; Rowley,
2007)

Purpose of the Study
This study aims to accomplish the following objectives
Examine the essence of knowledge.
Identify the elusive use of IQ dimensions to measure KQ.
Investigate conceptual and operational measurement of Data
Quality, Information Quality and Knowledge Quality through review
of literature.

Significance of Study
This review helps in exploring required dimensions for measuring OER knowledge quality which is the key contribution to the body of OER
literature.
Additionally, the dimensions can be utilized for measuring knowledge quality instrument.
The instrument would be useful to measure the OER knowledge
quality in terms of the knowledge gained by the user from OER
content.

Theory of Knowledge and Knowledge
Hierarchy
The tripartite definition discusses the theory of knowledge,
which argues that knowledge must encompass ‘justified,
true, belief’; the three indispensable conditions to fulfil the
essence of knowledge (Lehrer et al., 1969; Plato,
1921,1967).
Knowledge hierarchy functionally relates the data,
information and knowledge. These terms hold separate
dimensions at each stage that collectively lead to
knowledge starting from the data (Braganza, 2004).

Critique
Previous researchers have used the modified version of either Wang
and Strong’s (1996) DQ dimensions or Delone’s (2003) IQ dimensions
to measure KQ (Chiu et al., 2006; Halawi et al., 2007; Jennex and
Olfman, 2006; Liu et al., 2010; Rao and Osei-Bryson, 2007).
DQ dimensions that are Access Security, Accessibility, Accuracy, Appropriate Amount of Data, Believability, Completeness,
Conciseness, Consistency, Current, Interpretability, Level of Detail,
Objectivity, Relevancy, Reliability, Representation Consistency, Reputation, Timeliness, Understandability, Usefulness, and Value
Added, are adapted for measuring IQ by introducing two further dimensions, i.e. Updated and Verifiability.
However, KQ construct has faced serious negligence; none of the
researchers proposed any new dimensions

Conceptualization and Operational
Measurement of KQ Hierarchy
Quality knowledge encompass truthiness, justification, newness and
actionable nature (adaptable, applicable, and expandable)
Collectively three attributes of tripartite definition (JTB) meet the
essence and quality of knowledge.
Knowledge that is new, innovative, and useful for the
organisation/institution/system fulfils the requirements of quality
knowledge (Chan et al., 2008).
Knowledge is about action and must be used to some end’

Research Design
The exploratory research design is opted.
Exploratory sequential Mixed-method design will be used (Creswell
et al., 2010). Also referred to as instrument development design or
the quantitative follow-up design (Creswell et al., 2003; Morgan,
1998).

For Qualitative Data: Purposive sampling. Participants should be
