The success of an intervention depends not only upon its theoretical soundness, but also on proper implementation that reflects
the guidelines derived from its theoretical conception. Debates surrounding the effectiveness of problem-based learning (PBL)
have focused on its theoretical conception and students’ learning outcomes, but implementation is seemingly absent from the
picture. This paper attempts to describe what research evidence is needed to fill in this missing information and provide
a clearer picture of PBL. The author examines current PBL implementation practices and identifies potentially confounding
variables that may play a role in inconsistent or conflicting research results in PBL. For example, various models of PBL
have been developed and implemented to afford the specific instructional needs of the institution or learner population. These
PBL models are in fact quite different in terms of the nature of problem solving and the degrees of self-directed learning,
which theoretically, should result in different types of learning outcomes. Without distinguishing the models used, the results
of comparative PBL research could have been confounded. Furthermore, human factors are another set of confounding variables
that could influence the students’ learning processes and consequently affect PBL implementations and research results. To
remedy these problems and reach PBL’s full potential, as well as obtain a more accurate picture of PBL as an instructional
method and its effects on students’ learning, some fundamental changes are needed. 相似文献

Early childhood is a critical period of rapid physical, cognitive, and psycho-social development of a child. The quality of
care and education which a child receives at this crucial age will determine to a great extent the level of his/her physical
and cognitive development in the future. In Nigeria, Early Childhood Care, Development and Education (ECCDE) is an aspect
of Universal Basic Education which was introduced in 1999 to increase the access of children to basic education and improve
the state of education in the country. While all hands are on deck to ensure successful implementation and achievement of
the objectives of the scheme, it is unfortunate that ECCDE is facing some challenges thus making it unrecognized in Nigeria.
This paper examines the challenges of early childhood education in Nigeria. To improve the situation, the following measures
are recommended: establishment of more public crèche, kindergarten, and nursery schools by the government; enforcement of
the use of mother tongue in the teaching of children; training more personnel in the field of early childhood education in
tertiary institutions; and introducing unified curriculum as well as providing more infrastructures. 相似文献

Lynne Cherry Brandwein Lecture March 2010 National Science Teachers Association (NSTA) Conference, Philadelphia, PA. Young
Voices on Climate Change: Inspired and Empowered Youth Tackle Climate Science and Find Climate Solutions. As a child, Lynne
Cherry was profoundly connected to the natural world and a special place. She watched the destruction of her world. Now, through
her Young Voices on Climate Change project, she is trying to give teachers and young people the tools to prevent planetary
meltdown on a greater scale. Global climate change is upon us and the need for education and action is immediate. Outreach,
visual storytelling, and scientific understanding are especially necessary in light of the recent polls that show that the
public is becoming more confused and less concerned about climate change. Cherry’s climate book, co-authored with photojournalist
Gary Braasch, and her Young Voices on Climate Change films feature climate solutions. They’re about win–win—save the environment,
protect human health, reduce global warming gases, demonstrate youth making a difference with practical tools, motivate engagement
in climate science, take pride in increased science literacy, reach young people through their hearts as well as their minds,
and save money. Although young people can help their parents, peers and communities understand climate science, they can also
show them that reducing CO2 is in their economic interest, and spur them to take action. School carbon reduction initiatives are spilling over into communities
yielding measurable results in both global warming gas reductions and significant monetary savings. 相似文献

Part II of “Reclaiming Kindergarten” continues the discussion related to responding to the crisis in today’s kindergarten.
In Part II, two policy questions are posed, the answers to which seek to respond to this continuing crisis. The questions
center on issues related to engaging families in kindergarten and the need to consider a new early childhood paradigm where
kindergarten is part of a continuous and seamless educational experience spanning prekindergarten through third grade. As
in Part I, examples of classroom practice are used to illustrate the effective implementation of these principles in a kindergarten
classroom. 相似文献

The focus of this article is on articulating the importance of teacher development of constructs about homeless children and
families and examining factors that influence teachers’ perceptions of children and families who are homeless or at high-risk
of becoming homeless. The article also explores some strategies to support teachers in transforming their perceptions of homeless
children and provides case examples of how this process can work. Three case studies explore how teacher educators and practicing
teachers can work together to reflect on their own perceptions of homeless children from high-poverty backgrounds and how
educators were able to transform their own perceptions in being able to better serve their students. 相似文献

Early childhood teacher educators frequently enhance their teaching by reading children’s books to their adult students. It
is not unusual for faculty outside of early childhood to question devoting precious class time to read-alouds which they may
consider a curious, if not frivolous, instructional strategy. Quality children’s literature can, however, enhance students’
experiences in the college classroom, contribute to their understanding of course content, promote their personal growth and
self-understanding, increase their appreciation for quality children’s literature, and enhance their ability to integrate
storybooks into their own teaching. Children’s books often capture a child’s point of view. They have the potential to provide
historical or cultural perspectives on children and families. They also can lead to the examination of universal truths and
can facilitate the discussion of sensitive or emotional issues A list of books with suggested uses is included. 相似文献

This editorial examines neuroscience and its impact on the field of education. Starting with a narrative between two young
children, the author intertwines research with basic principles of learning, using the interaction between two 4-year-olds
to illustrate the precepts. The four principles are: (1) the brain is uniquely organized; (2) the brain is continually growing;
(3) a “brain-compatible” classroom enables connection of learning to positive emotions; and (4) children’s brains need to
be immersed in real-life, hands-on, and meaningful learning experiences. The editorial concludes with an illustration of how
the brain works while two children are playing at the small animal center in their classroom. 相似文献

This study examined changes in student motivation and achievement in science during a visit to a university children’s science
museum. The study was based on the pretest–posttest control comparison group design with four treatment groups: control, exhibit,
lesson and exhibit/lesson. The sample consisted of 228 sixth-grade students from a Louisiana public school who were randomly
assigned to one of the four experimental groups. Pretest, posttest and delayed posttest measures of intrinsic motivation and
achievement in science were obtained using the Children’s Academic Intrinsic Motivation Inventory and an achievement test
written to measure areas of science incorporated in the museum exhibits. The data were analysed using a one-way ANOVA, dependent
t tests and Pearson r. Significant differences were found within groups for (1) the lesson group in motivation and (2) the exhibit group in achievement
from pretest to posttest and from posttest to delayed posttest. A significant relationship between level of motivation and
science achievement was revealed for the exhibit group on the delayed posttest. There were no other significant findings to
support that the treatment led to any long-term effects on motivation or achievement within any of the four experimental groups. 相似文献
