1. Introduction
In a 2006 commentary on the status of science education in the United States, the Nobel
prize winner Carl Wieman and his colleague Katherine Perkins (Wieman & Perkins,
2006) asserted that “there is considerable evidence that science classes from elementary
school through to university are generally failing to provide most students with a
thorough understanding of science that will allow them to live and work successfully in
the twenty-first century. Sadly, these classes are also frequently suppressing whatever
interest students may have in the subject” (p. 290). Similarly, a European Commission’s
report entitled “Science Education Now: A renewed pedagogy for the future of Europe”
(2007) affirmed that many studies have identified an alarming decline in European
young people’s interest in science and blamed this decline on the way science is taught
in schools. Concurrently, research has shown that citizens of developing countries lack
the necessary knowledge and skills in science and technology to function in the modern
world (Ogawa 1998). What makes the above findings worrying is that they have
emerged at a time when education, political, economic, and community leaders
worldwide have agreed that science and technology are the catalysts for change in
modern society and when science is needed by all citizens to make informed decisions
regarding science-related scientific issues such as global warming and the green house
effect.
Against this backdrop of alarming news, what are the teaching approaches that are
recommended to improve the quality of science education and what does research say
about the status of science education worldwide. Consequently, the purpose of this
chapter is to summarize the major trends in promising approaches to teach science,

with knowledge transmitted by the teacher. Rather, they believe that most people learn
best through personal experience and by relating new information to what they already
PL O
know. They also understand that learners need to construct their own scientific
M SC
society and to develop attitudes that will help them to use their knowledge and skills
responsibly when taking every day and professional decisions. They must develop skills
that are particularly important for effective functioning in the ever-changing world of
work in which the traditional bases of economic competition continue to change
(Partnership for 21st Century Skills, 2011). This requires that students develop a strong
conceptual base and essential problem solving and critical thinking skills that they can
apply in a variety of situations; knowledge and skills that should be the focal points of
teaching and learning science in the classrooms of the twenty first century (Resnick,
1999).
To be effective and efficient citizens of the scientific and technological world in which
we presently live and in order not to be alienated, overwhelmed, and demoralized by the
changing world, it is not sufficient for students to remember information in the same
way it was presented in class; that is to learn by rote. Instead, they need to be able to use
what they have learned in novel situations to answer new questions, solve new
problems, relate what they have learned to everyday life, and facilitate learning new
subject matter; that is, to learn meaningfully (Mayer, 2002). Rote learning is described
as learning new information through the use of memorization. It suggests the absence of
connections between new and previously learned information. Because new information
is not connected to existing concepts in the learner’s mind, it is easily forgotten
(Anderson & Ausubel, 1966). In contrast, meaningful learning, described by Ausubel
(1968) as the establishment of non-arbitrary relations among concepts in the learner’s
mind, is the fundamental process that underlies the acquisition of useful information and
the construction of new knowledge (Novak, 1990). BouJaoude (1992) argued that
students who are able to establish connections among concepts and other forms of
knowledge are more likely to understand and remember what they learn. Also, they
might be able to address misunderstandings and to solve problems through the use of
the relations they construct between new knowledge and relevant existing concepts.
There are a variety of ways by which students can accomplish meaningful learning. In
S
TE S
the following the author describes a number of strategies that can be used for
meaningful learning including concept mapping, analogies, summaries and answering
R
AP LS
questions, inquiry strategies, and conceptual change strategies, strategies to address
environmental issues, and using ICT in teaching and learning.

2.1. Concept Maps
One of the teaching/learning strategies that have been shown to enhance learners’
science achievement and meaningful understanding is concept mapping. Concept
mapping has been used in science education in a variety of ways. Concept maps, for
E –
H
example, can play a significant role in curriculum development, learning, and teaching
in many disciplines (Novak, 1998). They are useful in science curriculum planning for
PL O
separating significant from trivial content (Starr & Krajcik, 1990). Furthermore, concept
M SC
maps have been used as assessment tools because they measure dimensions different
from those revealed by traditionally used assessment instruments (Markham, Mintzes,
& Jones, 1994). Finally, concept maps have been used in instruction in a variety of
contexts. Each context reflects an alternative theory of knowledge acquisition. On the
SA NE
one hand, the rationalist theory of learning suggests that subject matter has an inherent
structure that should be conveyed to learners. In this context, a concept map should be
evaluated by relating it to an ideal map, teacher-constructed map, or an expert concept

2.3. Inquiry Strategies
AP LS
Science has a unique nature and specific teaching strategies might be needed to help
students to understand the content, methods, and nature of science. Contemporary
C EO
conceptions of the nature of science suggest that scientific knowledge is empirically
based, tentative, and value laden. Moreover, scientific knowledge is inferential, creative,
and socially and culturally embedded. The fact that science is by nature empirical,
tentative, value laden and socially embedded necessitates emphasizing meaningful
E –
learning, because, when students learn science by rote they develop unrealistic and
H
There are different strategies by which teachers can provide the context within which
students can learn science meaningfully while concurrently understanding the nature of
M SC
thinking of the big picture, allowing for processing time, and promoting in-depth
interdisciplinary inquiry.
Science educators have developed many student-centered strategies to enhance
U
meaningful learning and help students understand the nature of science. One of the
characteristics of these strategies is that they are both hands-on and minds-on, a
characteristic that allows students to manipulate objects and experience events while at
the same time engaging their minds in thing about science and reflecting on their
experiences. Two of these strategies, general inquiry and problem-based learning are
described in the following.
Inquiry is a teaching strategy that aims to teach students about conducting investigations
and using and assessing evidence in order to answer questions or solve problems.
Scientific inquiry, specifically, refers to the varied ways by which students emulate
scientists by studying the natural world and proposing explanations based on the
evidence derived from their work. Inquiry also refers to the activities of students in
which they develop knowledge and understanding of scientific ideas as well as an
understanding of how scientists study the natural world. Inquiry teaching aims to
develop students’ higher order and critical thinking skills and in-depth and meaningful
S
TE S
scientists work; b) relating content to students’ experiences and prior knowledge; c)
encouraging students to be curious about the world around them, d) providing
R
AP LS
opportunities for integration across different content areas; e) developing students’
communicating skills through sharing of thoughts and collaborative work; and f)
preparing students to be citizen who take informed decisions about science related
C EO
issues.
The extent of teacher guidance during inquiry depends on the learners’ cognitive level
and the level of sophistication in conducting investigations. Herron (1971) developed a
scale that provides teachers with guidelines for using and assessing inquiry in the
E –
classroom (Figure 1). Level 0 is usually used with students who are new to inquiry.
H
Thus they are given the problem, the procedure to follow as well as the solution or
PL O
expected answer. Level 1 is used with students who are a little more advanced, thus they
get the problems and procedure and are required to reach the solution themselves. In
M SC
level 2, the students are only given the problem and are required to develop the
procedure and reach the solution. In level 3, students come up with their own problem,
develop their own procedure, and reach their own solution. This is open inquiry that

While inquiry in science was the focus of the science education standards in the 20th
century, the reformulation of these standards in the 21st century emphasizes the inter-
relationships of science, technology, engineering and math in what is now known as
STEM education which focuses on scientific inquiry and engineering design (National
Research Council [NRC], 2011a). For example, the document entitled “A Framework
for K-12 science education: Practices, crosscutting concepts, and core ideas” suggests
that in the United States all students should have “some appreciation of the beauty and
wonder of science; possess sufficient knowledge of science and engineering to engage
in public discussions on related issues; are careful consumers of scientific and
technological information related to their everyday lives; are able to continue to learn
about science outside school; and have the skills to enter careers of their choice,
including (but not limited to) careers in science, engineering, and technology.” (NRC,
2011a, p. ES 1).
A variety of specific teaching strategies have been advocated to involve students in
S
TE S
inquiry leaning. These include problem-based learning, Predict, Observe Explain
(POE), the learning cycle, and the 5-E learning cycle. Problem-Based Learning (PBL) is
R
AP LS
a form of experiential learning that involves students in posing real-world problems,
preferably from the students’ environment, and using resources, under the guidance of
the teacher, to resolve the problems while at the same time developing content
C EO
knowledge and problem solving skills associated with the problem. The POE’s three
steps allow students to predict what might happen if an event were to take place,
observe what actually happens, then amend their explanations if what they had
predicted contradicts what they observed or add to their original explanations to account
E –
for the observations. The learning cycle involves three steps and requires students to
H
explore, explain, then apply, while the 5-E model – which is an extension of the
PL O
learning cycle – involves engaging students in an activity, allowing them to explore the
problem identified in the activity, explain the results of their exploration, extend their
M SC
As indicated above science educators realize that students’ brains are not empty vessels
waiting to be filled with knowledge transmitted by the teacher. Rather students come to
the classroom with preconceived notions and understandings that they have developed
U
from their experiences. These preconceived notions are sometimes at variance with
accepted scientific knowledge and are called alternative conceptions (or
misconceptions). The existence of misconceptions has been documented in hundreds of
research studies worldwide. The existence of alternative conceptions necessitates the
use of conceptual change strategies that address them directly because they have been
resistant to change by ordinary teaching methods.
One of the first models of conceptual change was developed by Posner, Strike, Hewson,
& Gertzog (1982). This model posits that there are four conditions for conceptual
change to succeed: there should be dissatisfaction with existing concepts and new
concepts should be intelligible, plausible and fruitful. This model was however
criticized because it is overly rational and because it neglects motivational factors such
as students’ goals, values, self efficacy beliefs, and control beliefs (Treagust & Duit,
2008). Others have criticized this model because of its lack of emphasis on context as a
mediator of conceptual change (Treagust & Duit, 2008). Another popular model of
conceptual change was developed by Driver and Scanlon (1989). This model includes
five steps: 1) Orientation, during which students are introduced to the task, 2) elicitation
of students’ ideas, 3) restructuring of ideas during which students are involved in a
variety of activities to restructure their ideas, including the exposure to cognitive
conflict among other activities, 4) application of the new ideas in new situations, and 5)
review change of ideas by comparing the initial ideas to the new ones.
It is worth noting that cognitive conflict (or the use of discrepant events) has played an
important role in conceptual change models with research. However, the use of
cognitive conflict has also been criticized because it does not always lead to successful
and permanent conceptual change (Treagust & Duit, 2008). In conclusion, Treagust and
Duit (2008) assert that multi-dimensional conceptual change perspectives that consider
both cognitive and affective outcomes of learning as conceptual change seem to be
more effective than ones that do not consider these factors even though there have not
been meta-analytical studies that confirm this conclusion.

2.5. Strategies to Address Environmental Issues
R
AP LS
Students living in the 21st century will eventually have to participate in decision-making
regarding science-related issues that are environmental or controversial socio-scientific
C EO
in nature. Preparation for such participation can be accomplished by adopting a science-
technology-society-environment approach (STSE).
The aims of including STSE issues in the teaching of science are helping students to
E –
learn and understand science content and at the same time make informed decisions
H
science curriculum by using a variety of strategies that include the study of products and
systems, issues awareness, moral development, issues investigation and action learning.
M SC
While action learning is the ultimate aim of using STSE approaches, students need to
develop the skills to investigate issues in preparation for decision making and action
learning.
SA NE
These skills include identifying and clarifying the basic question to be answered,
gathering data about the issue under study, evaluating the data, proposing tentative
U
solutions, and determining the acceptability of the solution in the context where it is
being considered.
Two strategies that can be used to investigate issues are the Futures Wheel (BouJaoude,
2000) and the Issues Analysis Technique. The futures wheel is a teaching technique that
encourages students to think creatively in exploring the implications of a particular issue
or event.
There are no right answers when completing a futures wheel and no decision-making
occurs. Rather, it is used to analyze issues in preparation for decision-making. When
developing a Futures Wheel students look at an event, experience or decision and ask
"What might happen if...?" and construct a graphic representation of the direct and
indirect effects of the issue or event that is being analyzed. Similarly, the issues analysis
technique involves students in analyzing issues by identifying the Problem, the issue,
the players who have a role in the issue, the positions of the players concerning the
issue, the beliefs held by the players, and the values on which the beliefs are based.
Based on this analysis, various strategies to resolve the issue are identified.
