Resources for Best Practices



Central concepts:

 beliefs shape program development

 model programs yield conclusions about

effective practice

 effective practice increases pupils' science

achievement, skills, and attitudes

 supported assumptions shape new

program development









T11.0

Early Efforts in Science Reform

T11.2

 The 1957 Soviet launching of the satellite Sputnik

initiated science education reform in the United States.

 In the twenty-five years since Sputnik the United States

has spent more than $2 billion in the development of

elementary and secondary mathematics and science

curriculum with the goal of preparing future scientists

and engineers.

 Early elementary science curriculum reform was known

as the alphabet soup era named for the three lead

programs SAPA, SCIS, and ESS.



T11.1

The Alphabet Soup

 Science A Process Approach, Science Curriculum Improvement

Study, and Elementary Science Study were designed and field-

tested during the 1960’s, revised in the 1970’s, and underwent

changes in the 1980’s and 1990’s. SAPA II materials are still in

use in the 2000’s.

 They were successful in that they were developed based on

assumptions about learning drawn from prominent learning

theories.

 Each project was developed from teaching strategies consistent

with how children learn best.

 The students played and active role each in curricula, with the

teachers serving as facilitator and guide for learning.



T11.2

The Alphabet Soup (cont.)

 Specific science processes or content areas were selected for

each project, thus narrowing the field of topics to a specialized

few.

 Attention was given to the basic ideas of science, the concepts

and theories.

 All equipment for science activities were packaged with the

curriculum materials.

 Mathematical skills were emphasized. Science process skills

were embedded within all activities.

 The emphasis was placed on doing science, not merely talking

about what scientists do!





T11.3

What Works?

Hands-on, minds-on approaches can be superior

to direct, prescriptive approaches:

 produce greatest gains in achievement,

processes, and attitudes (Table 11.1)

 benefit disadvantaged learners

 improve thinking

 provide intrinsic rewards

 improve retention







T11.4

Attitudes 20 3 15

Process skills 18 21 36

Related skills * 8 4

Creativity 26 34 10

Piagetian tasks 2 5 12









T 11.5

Supported Assumptions

Effective science programs:

» Favor a wholistic view of science

» Includes features that aim to improve

student’s science attitudes, skills, and

content knowledge.

» Promote inquiry-based, hands-on

curriculum and teaching approach.

» Attempt to cover less material, but have the

learners do more to learn at a greater depth





T11.6

Selecting and Using Textbooks



 Even with the reform of science curriculum from the

1960’s the research shows that 21st century

classrooms still rely on a single textbook as the basis

for science instruction.

 Science textbooks still contain some shortcomings in

the areas of gender bias, persons of color, people with

disabilities, and science vocabulary continues to be

emphasized much more than science concepts.

 Texas, California, Florida and North Carolina all have

statewide adoption of textbooks.

» Their student population account for 25% of

school students in the United States.

» Textbook selection committees of these states

tremendously influence the content that most

publishers choose to put into their textbooks.

» Thus a few states tend to determine the content

and features offered to the rest of the nation.









T11.7

Enhancing the Textbooks



The teacher can enhance the textbook to include

more effective learning activities and interesting

information.

This can be done by:

Selecting relevant supplements from web-based materials.

Identifying local resources such as school and community

professionals, local businesses, parks and recreation

facilities, libraries, and museums to serve as rich resources

for classroom speakers and field trips.

Selecting evaluation devices that reflect the preferred

outcomes.





T11.8

Changing the Sequence

 The textbook’s chapter order and organization may

not be what is best for your students. Resequencing

may bring improvements in achievement, attitudes,

and interest to help your learners make clearer and

stronger conceptual connections. See Table 11.2.

 Resequencing material so ideas relate in ways that

make more sense to the learner adds meaning.

 Concept mapping is a method of sequencing of ideas

of a lesson, a version of this can be used to

sequence the text effectively.



T11.9

Selecting the Best Textbook

When screening texts one should ask:

 What does the book expect my students to do?

 What should the students be able to do after they study

the textbook that they could not do before?

 Does the text include important content and related

information?

 With every activity or student project what kind of thinking

is required? How does this address the National

Standards?

 Will this text help my students reach the goals I have set

for them?

 See Table 11.3



T11.10

Using Trade Books

 Trade books use children’s literature as another way to bring

content-focused science materials to the classroom.

 The trade book can provide an aesthetic or emotional dimension

to learning.

 Can involve a wider audience and offer an applied setting for

learning science.

 Trade books include biographies, reference books on science

phenomena, may use fictional characters to illustrate specific

science concepts.

 The annual March issue of the NSTA publication Science and

Children lists the most outstanding science trade books for

children.





T11.11

Using Trade Books (cont.)

 Trade books have their limitations.



 May be used to introduce or complement a lesson or

to support vocabulary and help develop the concept.



 Teachers must carefully scrutinize trade books just

as they would a textbook.



 Some researchers have found that many trade books

contain factual errors, or information and illustrations

that encourage the formation of misconceptions.





T11.12

Best Practices



 “Best practice” is a term used to convey a clearly

defined basis for making an evaluation about a

resource’s or a practice’s impact on learning.



 A “best practice” consists of superior teaching

materials that are used with effective teaching

methods.



 Choosing and using a “best practice” should

result in a significant impact on student learning.







T11.13

Identifying Best Practices



A best practice resource will:

» Be aligned with specific content, teaching and

assessment standards.

» Have a research base.

» Have accurate content that is developed in a way

that promotes student understanding.

» Implicitly or explicitly support equity.

» Engage the interests of most students using

methods of inquiry and require active participation

for learning to occur.



T11.14

Identifying Best Practices (cont.)







 A best practice resource will:

» Frame the content in a learning context that is meaningful

and significant to the learner.

» Be adaptable to a variety of learning settings and promote

discourse which leads to constructed understanding.

» Use appropriate technology in highly effective ways.

» Include tools to help teachers conduct assessments of

increased student learning.

» Innovate, motivate, and hold high expectations for learners.

 A web-based science resource used to identify hundreds of

“best practices” science resources is the Ohio Resource Center

for Mathematics, Science and Reading (ORC) found at

http://www.ohiorc.org





T11.15

Resources for Best Practices



 Current resources strive to serve the needs and interests of all

learners, not just the intellectual elite.



 New programs emphasize conceptual development through

constructivist techniques, use multiple teaching methods to fill

multiple student interests, and incorporate multiple views on

human diversity. See table 11.5.



 Continued classroom testing of materials and lessons and

frequent revision through formative evaluation reduce

conceptual flaws and expand the supported assumptions about

learning.







T 11.16

Resources for Best Practices (cont.)



Numerous small-scale efforts to produce the next

generation of science programs. Some that have

endured rigorous evaluation include:

 AIMS – Activities Integrating Mathematics and Science;

Delta Science Modules; Earth Systems Education; Project

Learning Tree; Project WILD and Aquatic Project WILD

 The Lawrence Hall of Science in Berkeley, CA has

developed and still distributes the Full Option Science

System (FOSS), Primary Exploration for Adults, Children

and Educators in Science (PEACHES), Science Education

for Public Understanding Program (SEPUP), and Science

Activities for the Visually Impaired/Science Enrichment for

Learners with Physical Handicaps (SAVI/SELPH).

T 11.17

Resources for Best Practices (cont.)



Human Resources

 colleagues are readily available and often ignored,

they can expand the teaching experience

 community volunteers can provide expertise in a

variety of areas (Table 11.6)

 volunteers can help in many capacities; not all will

feel comfortable getting up in front of a group of

students (Table 11.7)
