Model development as a research tool: an example of PAK-NISEA.
Shafique, Farzana ; Mahmood, Khalid
Introduction
Research is an inquiry process that has clearly defined parameters
and has as its aim the discovery or creation of knowledge, or theory
building; testing, confirmation, revision, refutation of knowledge and
theory; and/or investigation of problem for local decision making
(Hernon, 1991). Leedy and Ormrod (2001) put it as "the systematic
process of collecting and analyzing information (data) in order to
increase our understanding of the phenomenon about which we are
concerned or interested".
Research provides theoretical foundations for any discipline and
helps in its development. Unfortunately, research in librarianship is
still in its embryonic stage and lack a body of knowledge (evidence
based). Keeping this in view, Haddow (1997) stressed that if librarians
fail to build a body of knowledge, it will be difficult to develop this
profession. The status of librarianship's intellectual base, the
degree of scholarship, must be regarded with some suspicion. Librarians
should actively seek to address these criticisms by adding their
research to the growing body of knowledge. Similarly, Busha and Harter
(1980) have pointed out that if librarianship is to merit the in demand
designation "science," a significant number of scholars and
research workers must regularly apply scientific method to analyze
relationships among the problems which librarians are obligated to
explore and which they are qualified to solve. Moreover, the study of
library science can attain recognition as a true science only when a
general body of theory is developed.
Research Methods Used in Librarianship
Koufogiannakis and Crumley (2006) have reviewed the current trends
of research in librarianship and found that there are several areas
which contain more research than others. Consistently, topics in
information storage/access/retrieval have greater amounts of research
being published, as do collectionsrelated issues, and service
activities. On the other hand, the areas of information seeking, LIS
analysis, LIS education, LIS theory, history, methodology, the
profession, publishing and scientific and professional communication all
have less research being published. There are huge gaps in our evidence
base in these latter areas and they all require further exploration to
move our profession forward. Busha and Harter (1980) and Powell and
Connaway (2004) have listed many research methods which are currently
used in librarianship. For example:
Experimental Research
It is a research method, in which the researcher attempts to
maintain control over all factors that may affect the result of an
experiment. In doing this, the researcher attempts to determine or
predict what may occur (Key, 2002). It is a collection of research
designs which use manipulation and controlled testing to understand
causal processes. Generally one or more variables are manipulated to
determine their effect on a dependent variable
(Experiment-Resources.com, 2009).
Survey Research
Survey research is one of the most important areas of measurement
in applied social research. The broad area of survey research
encompasses any measurement procedures that involve asking questions of
respondents. Surveys can be divided into two broad categories: the
questionnaire and the interview. Questionnaires are usually
paper-and-pencil instruments that the respondent completes. Interviews
are completed by the interviewer based on what the respondent says
(Trochim, 2006b).
Historical Research
Sometimes we gain the best knowledge by looking into the past
rather than into the future. Historical research attempts to do just
that. Through a detailed analysis of historical data, we can determine,
perhaps to a lesser extent, cause and effect relationships. Historical
research can also mean gathering data from situations that have already
occurred and performing statistical analysis on this data just as we
would in a traditional experiment. The one key difference concerns the
manipulation of data. Since historical research relies on data from the
past, there is no way to manipulate it. Therefore, historical research
can often lead to present day experiments that attempt to further
explore what has occurred in the past (AllPsych & Heffner Media
Group, 2003).
Operations Research
Operations research (OR) is the application of scientific method to
management operations in an effort to aid managerial decision-making.
Techniques of operations research are concerned with the activities of
organizations, or systems, and are designed to provide management with a
quantitative basis for decision making (Busha & Harter, 1980).
Additional Research Methods in Librarianship
Observation and Description: Gorman and Clayton (2005) define
observation studies as those that "involve the systematic recording
of observable phenomena or behavior in a natural setting" (p. 40).
It is a branch of anthropology that deals with the scientific
description of specific human cultures and has a long history. It
permits researchers to study people in their native environment in order
to understand "things" from their perspective. Until recently,
few library and information science studies have included this method;
however, observation is gaining favor as LIS researchers seek to
understand better the role of information in people's everyday
lives (Free Library, 2009).
The Case Study Method: Case study research excels at bringing us to
an understanding of a complex issue or object and can extend experience
or add strength to what is already known through previous research. Case
studies emphasize detailed contextual analysis of a limited number of
events or conditions and their relationships. Researchers have used the
case study research method for many years across a variety of
disciplines. Social scientists, in particular, have made wide use of
this qualitative research method to examine contemporary real-life
situations and provide the basis for the application of ideas and
extension of methods (Yin, 1984).
Library User Studies: According to King (2005), information needs
and expectations are continuously changing in the rapidly changing
information scenario. Libraries need to re-orient their collections,
services, and facilities to keep pace with these advancements. User
feedback is considered as a more reliable factor in measuring the
utility and effectiveness of any library. By making user surveys a
regular part of the library's functions, librarians can provide a
comparative 'snapshot' of usage in various temporal contexts.
Evaluation Research: Evaluation is a methodological area that is
closely related to, but distinguishable from more traditional social
research. Evaluation utilizes many of the same methodologies used in
traditional social research, but because evaluation takes place within a
political and organizational context, it requires group skills,
management ability, political dexterity, sensitivity to multiple
stakeholders and other skills that social research in general does not
rely on as much (Trochim, 2006a). According to Busha and Harter (1980),
studies conducted to obtain objective and systematic evidence of the
success or failure of library project and programs are often categorized
as evaluation research. When a program is evaluated, its relative
effectiveness in terms of standards, goals, and objectives is determined
and described.
Library Surveys: Research studies designed to survey library
conditions and services with an aim of improving their overall quality.
Between 1930 and 1950, the library survey was among the most frequently
used methods to observe, analyze, compare, and describe general
conditions in and related to libraries. Many such efforts were status
surveys, designed primarily to merely evaluate library conditions rather
than to test hypothesis or to explore specific research questions
thoroughly (Busha & Harter, 1980).
Community Surveys: Closely related to library survey is another
descriptive approach-the community survey. Designed to allow careful
inspections of the characteristics of communities and to relate the
features to library goals and objectives, community surveys are attempts
to obtain a detailed working knowledge of various pertinent dimensions,
geographic areas, or publics served by libraries. A purely descriptive
community survey is designed to characterize properties and conditions
of a group of people living or working together in a district or within
an institution. An exploratory community survey devotes attention to
interrelationships between these characteristics and the use of various
library resources, programs, and services. Some community surveys are
attempts to accomplish both of these tasks (Busha & Harter, 1980).
Comparative Librarianship: It is a systematic analysis of library
development, practices, or problems as they occur under different
circumstances (most usually in different countries)-considered in the
context of the relevant historical, geographic, political, economic,
social, cultural, and other determinant background factors found in the
situations under study (Collings, 1971).
Content Analysis: Content analysis is a research tool used to
determine the presence of certain words or concepts within texts or sets
of texts. Researchers quantify and analyze the presence, meanings and
relationships of such words and concepts, then make inferences about the
messages within the texts, the writer(s), the audience, and even the
culture and time of which these are a part. Texts can be defined broadly
as books, book chapters, essays, interviews, discussions, newspaper
headlines and articles, historical documents, speeches, conversations,
advertising, theater, informal conversation, or really any occurrence of
communicative language. To conduct a content analysis on any such text,
the text is coded, or broken down, into manageable categories on a
variety of levels--word, word sense, phrase, sentence, or theme - and
then examined using one of content analysis' basic methods:
conceptual analysis or relational analysis (Colorado State University,
2009).
Delphi Method: Collaborative estimating or forecasting technique
that combines independent analysis with maximum use of feedback, for
building consensus among experts who interact anonymously. The topic
under discussion is circulated (in a series of rounds) among
participating experts who comment on it and modify the opinion(s)
reached up to that point (BusinessDictionary.com, 2009).
Documentary Research: Documentary research is the use of outside
sources to support the viewpoint or argument of an academic work. The
analysis of the documents in documentary research would be either
quantitative or qualitative analysis (or both) (Balihar, 2007). It
involves the use of texts and documents as source materials: government
publications, newspapers, certificates, census publications, novels,
film and video, paintings, personal photographs, diaries and innumerable
other written, visual and pictorial sources in paper, electronic, or
other 'hard copy' form (Scott, 2006).
Model: Another method or device often used by scientists is the
model, a verbal, mathematical, or graphical construct representing a
phenomenon (Busha & Harter, 1980).
Model Development: A Challenging Research Method for LIS
Researchers
Model development is considered an effective research method. It
assists investigators and scientists in relating more accurately to
reality; it also aids them to describe, predict, test or understand
complex systems or events. Thus, models often provide a framework for
the conduct of research and might consist of actual objects or abstract
forms, such as sketches, mathematical formulas, or diagrams. A model is
an abstraction, a mental framework for analysis of a system. It involves
simplified representations of real-world phenomena (Busha & Harter,
1980; Powell & Connaway, 2004, p. 60). In general terms different
authors suggested the importance of:
A theoretical framework for the definition, criteria and
characteristics of models;
* Practical guidelines that describe the procedural aspects of
model building;
* The availability of data defining the factual situation for the
model which is being constructed (Deal, 1986; Adeyemi 1975).
Characteristics of Models
According to Leimkuhler (1972), following are the characteristics
of models:
* Relatedness, to other models and techniques;
* Transparency, in terms of ease to interpretation;
* Robustness or sensitivity to assumption made;
* Fertility or richness in deductive possibility;
* Ease of enrichment or ability to modify and expand.
Important Role of Models in Research
Models have an important role in research. These can be applied in
research in terms of theoretical constructs (Adeyemi, 1975); testing and
understanding multifaceted system (Busha & Harter, 1980); and
creating connections between research and society (Weiss, 1979). Models
provide guidance for the completion of work or the establishment of
systems and refer to a representation of a real world phenomenon.
A model is a representation or abstraction of an actual object or
situation. It shows the interrelationships (direct or indirect) and
interrelationship of an action and reaction in terms of a cause and
effect. Since a model is an abstraction of reality, it may appear less
complex than reality itself. The model, to be completed, must be
representative of those aspects of reality that is being investigated
(Adeyemi, 1975, p.50). Busha and & Harter (1980) have stressed that
when models have not been properly validated, their employment as a
knowledge source might be unwarranted. In addition, unless care is
taken, models often invite overgeneralizations.
Use of Model Development in LIS Research in Pakistan
Very few efforts were made for developing and proposing models at
doctorate level LIS research in Pakistan. The efforts made include, a
plan proposed by Khan (1991) to be executed under the aegis of
University Grants Commission (Now known as Higher Education Commission)
to overcome the problems faced by the university libraries in terms of
inadequate materials and collections; slow and outdated technical
processing; shortage of funds; lack of manpower in quantity and quality;
absence of coordinated planning and lack of government attention; and
social urgency. Khalid (1997) argued that co-operation and networking in
library and information systems are frequently applied in developed
countries. These countries are getting maximum benefits from these
systems. Contrarily these systems are less used in developing countries.
Keeping this gap in view, Khalid proposed a model for the initiation of
cooperation and networking in countries with less developed systems.
Similarly, Mahmood (2004) proposed an 'Alternative Funding Model
for Libraries in Pakistan'. He argued that to improve library
services in Pakistan, libraries need adequate finance, which is not
available at the moment from the traditional sources. This study is
directed towards finding alternative sources of funding.
Other LIS professionals who have registered in PhD program and are
working to develop a model include, Khawaja Mustafa working on "A
model for network of health science libraries in Karachi" and Syed
Ataullah working on "Digital library initiatives in Pakistan: A
proposed digital library model for the Aga Khan University" (Haider
& Mahmood, 2007).
Model Development Approach for Proposing PAK-NISEA (Pakistan
National Information System for Educational Administrators)
In view of the significant global changes in almost every aspect of
modern life brought about by the science and technology, the role of
education is increasing by being re-defined. In the new situation
education has come to be acknowledged as a vital factor for human
development, which is the core of all developmental efforts. Developed
world achieved extraordinary socio-economic and technological
development because of the realization that education is an asset and
that a sound educational system is vital, which is capable of producing
better human resources and could help in recognition of better economic
and social goals.
In the process of development, education is, therefore, an
investment. This investment has to be made well in time to get full
benefits from the overall development efforts. Free flow of information
is obviously an essential requirement for achieving educational goals
and objectives. Educational administrators require various types of
information and data for efficiently carrying out their official
assignments. They can only do this in a context which allows them to
access, use, validate and communicate required information. In this
context, a number of factors are influencing building up of a sound and
reliable educational structure but the key factor is the user
centered/user friendly information system for educational administrators
which is a neglected connection in Pakistan's national scheme of
things. On the other hand, yet no comprehensive study at the national or
provincial level is conducted to find out the information needs and
seeking behavior of educational administrators which can assist in
designing an effective, efficient and user centered information system
for educational administrators at national level. Keeping this wide gap
in view, this study aimed at finding the information needs and seeking
behavior of educational administrators and proposing a comprehensive and
well integrated user centered/friendly national information system for
educational administrators for desired transformation in the education
of Pakistan. Following are the objectives of the study:
1. To review the existing information system of education in some
developed and developing countries.
2. To review the existing educational system and information system
of education in Pakistan.
3. To study the information needs and seeking behavior of
educational administrators.
4. To propose a model for the national information system for
educational administrators in Pakistan.
5. To validate the proposed model.
Flow chart presented in figure 1 shows the research methodology of
the study.

Model Development Process
This section explains the process of model development including
procedures used for literature search, instrument development, data
collection, and analysis.
Literature Review
To understand different theoretical and practical aspects of the
study, a thorough search of the relevant literature was conducted. For
this purpose, different aspects of information system were reviewed in
detail. Literature related to education system of Pakistan; information
systems especially in education at international and national level;
user studies conducted for finding the information needs and seeking
behavior of intended users especially educational administrators; role
of such studies in the development of effective information systems and
their implementation were collected and reviewed thoroughly. For
literature search standard sources were used e.g., Library literature,
theses, online resources.
Survey
Keeping in view the objectives of the study, a selected group of
experts from the public sector institutes, who, in their discharge of
day to day administrative work, had to depend upon the information
system in education, were identified with the help of reviewed
literature and discussion with experts. The educational administrators
i.e., Registrars/ deans/ heads of departments in universities and
principals of schools and colleges were identified as the target
population for the questionnaire survey. The respondents were from the
Punjab province and Islamabad Capital Territory (ICT). The choice of the
Punjab for the questionnaire survey and interviews is based on three
main grounds: (1) The researcher is based in Punjab and logistic support
for the PhD fieldwork was most conveniently available in this region;
(2) Circumstances in Balochistan and NWFP provinces are not in favor of
field survey; (3) The province is home to over half the population of
Pakistan. About 50% educational institutes are situated within Punjab
province and Islamabad Capital Territory (ICT).
For sampling purpose the Punjab province was divided into clusters
and sub clusters and each district was designated as a primary cluster.
It was tried to get response from each district. Then each district was
divided in sub clusters i.e. tehsils. Sub clusters (tehsils) were
randomly selected. Elements (i.e. schools, colleges and universities)
were selected according to a defined criterion. To get the reasonable
response, 300 (in total) responses were targeted from three groups of
respondents i.e. schools, colleges and universities. Three separate
questionnaires for school, college and university administrators along
with cover letter were distributed through mail, email and personal
visits. Many follow up letters, emails, telephone calls and personal
visits made the achievement of 97.6 percent response possible. The
quantitative data were analyzed with the help of SPSS version 15.
Descriptive statistics such as Mean, Mode, Median, Standard Deviation
etc. were used. Further inferential statistics such as Paired Sample
T-test, ANOVA and MANOVA were used to reach at conclusions.
Interviews
Semi structured interviews were also conducted. Sample for
interviews was chosen through purposive sampling. Interview of three
different categories of experts were conducted i.e., educational
administrators (i.e., ex Vice Chancellors, EDOs, DEOs, Deputy Chiefs of
Education in Planning Commission of Govt. of Pakistan etc.); Information
and library professionals (working on executive positions of well known
institutes); and Information system experts. In total 55 interviews were
audio recorded. The data acquired through open ended questions and
interviews; were analyzed qualitatively. These interviews and review of
the related literature helped in the overall understanding and designing
of the system. A pilot study was conducted to assess the reliability and
validity of the instruments developed for the study.
Important Features of the Proposed Model
Centralization: Due to its characteristics of reduced duplication,
utilization of resources, more centralized control and better
standardization, the proposed model is centralized. Interview with
information system, and library and information science experts made it
very clear that the proposed model should be centralized.
Pooling the Existing Information Systems/Services: Keeping in view,
the interview findings and existing practices of the world information
systems, the proposed information system will pool the existing
information systems and services.
Access and Services based on Knowledge Environment Model: Keeping
the survey and interview findings in view, the proposed products,
services and access will be based on the knowledge environment model.
Keeping in view the diversity of information needs of different level of
educational administrators, the proposed system seeks to offer both a
sophisticated technological environment and also a more traditional set
of services.
Development in Phases: The use of Spiral Model Approach: All three
categories of interview respondents mentioned that as the proposed model
will cover all three levels of education i.e. school, college and
university education, thus the model should emerge in phases and with
the successful completion of one phase, the other should be started. The
approach for this purpose used is "Spiral Model" in which the
objectives, alternatives and constraints are determined, mechanism is
developed for risk analysis, and then prototypes (sample models) are
developed and implemented. If successful, the next level plan is
developed and executed.
Clearly Defined Objectives and Activities of PAK-NISEA: The new
system requirements are defined in the coming section, after a
comprehensive system study of the various education enterprise processes
in Pakistan, in as much detail as possible. It involved survey and
interviewing internal and external users, preparation of detailed flow
diagrams showing the process or processes for which the IS is to be
developed, the inputs and outputs in terms of how the data is to be
recorded/ entered and the form in which the results are to be presented.
Following are the objectives of the proposed model:
* To provide information with easy access
* To provide update and current information in the field of
education
* Training of Educational Administrators
* To ensure availability of valid, reliable and needed information
* Training of other staff members i.e., Information
providers/librarians etc.
* To have linkage within educational institutes of the country
* To provide information according to the administrators'
specific needs
* To develop and maintain an online full text database of
educational documents related to administrators' information needs
* To generate and maintain adequate media of information
* To have linkage within educational information systems of the
world.
Risk analysis: Ongoing monitoring, maintenance and evaluation: It
is important part of the system development from initial stage to
complete implementation of each step. It includes addressing any factors
which may risk the successful completion of entire project of PAK-NISEA
development including alternative strategies and constraints.
Prototyping: Based upon the finalized strategy and the preliminary
design, the first prototype (sample model at a small scale) of the new
system will be developed.
[ILLUSTRATION OMITTED]
The system will be developed in phases. As a first prototype only
the system will prepare a module for higher education sector of the
Punjab province and Federal Area of Pakistan. As the results of the
survey and reviewed literature reveals that universities are fewer in
number and enjoying better ICT facilities so the first prototype would
cover higher education sector only.
Development and verification of next-level product: The prototype
prepared will be tested against benchmarks based on end users'
expectations and evaluated risks to verify the various aspects of the
development. Refinements and rectifications of the prototype will be
undertaken until target users' satisfaction is achieved before
development of the next level of the system.
[ILLUSTRATION OMITTED]
The second prototype will cover a module for secondary & higher
secondary education sector of the Punjab province and Federal Area of
Pakistan. The prototype 2 will be tested and verified.
[ILLUSTRATION OMITTED]
The third prototype will cover a module for primary education
sector of the Punjab province and Federal Area of Pakistan. The
prototype 3 will be tested and verified.
Plan of next phase for other provinces: The preceding steps are
iterated until the end user is satisfied that the refined IS represents
the final product desired. The final IS will be constructed based on the
refined prototypes. The final system (An information system for Punjab
Province and Federal Area of Pakistan, covering school, college and
university sectors) will be thoroughly evaluated and tested. Routine
maintenance will be carried out on a continuing basis to prevent
large-scale failures. In the next phase of the plan applying above three
prototyping approaches the NISEA will be developed in NWFP & AJK,
Sindh, and Baluchistan provinces as well. A final product will be a
National Information System for Educational Administrators in Pakistan.
Components of PAK-NISEA
The components of the proposed information system include: a)
geographic acquisition and distribution coverage and type of information
acquired, b) primary users, c) media classification, d) information
acquisition, e) information selection, f) information processing, g)
information storage, h) products and services, and i) management
structure and funding.
Validation of the Model
The draft model is sent to the experts of education, information
system and library and information science for validation. For this
purpose some national and international experts/professionals, who are
well known in their respective fields were contacted through mail/e-mail
and were requested to give their comments on the draft of proposed
model. Observations received will be qualitatively analyzed and
ideographically summarized (Till the writing of this paper, the model is
in validation phase). In the light of experts' opinion, necessary
amendments will be made to the model before final presentation in the
dissertation.
Conclusion
The model development is an effective research method which
provides a logical guideline to the researchers in proposing any new
system or services etc. This tool helped, in this study, to propose a
user centered/friendly information system for educational administrators
in Pakistan. Following recommendation are made on the basis of this
study:
As research provides theoretical foundations for any discipline and
helps in its development, the LIS professionals should engage themselves
in research for the development of their profession.
* Model development has proved to be an effective research tool. It
should be used more frequently in LIS research as well. LIS researchers
in Pakistan should pay special attention on it.
* The example of PAK-NISEA explains the logical steps of model
development. Other researchers should take help from this experience.
