The teacher’s focus should target encouragement of theirstudents’ own reflection on their reasoning as well as interpretation of problem situations 25.Contrary to current practices of warning students when they take a wrong step in their solutionefforts, teachers need to encourage students to focus on interpreting specific ideas and theirconnections to the problem at hand 26. This type of facilitation requires significant scaffoldingmechanisms for effective learning to take place 27. The new role of the teachers includescarefully selection, preparation, and implementation of those scaffolds 16, 28. Lack of sufficientguidance will

However, K-12 science education willalso have to reform and support the work of engineering education if improvements in thescience classroom are to be made.In response to this, A Framework for K-12 Science Education: Practices, Crosscutting Concepts,and Core Ideas has been developed by the Carnegie Corporation of New York and the NationalResearch Council and represents a new conceptual framework for science education. Theimpetus for this project stems from the growth of knowledge of science, increased understandingof the learning and teaching of science, and the need for scientific and engineering practices tobe represented in the science classroom. The framework is organized within three

Once the work experience is complete, the teachers receive a $2,000 stipend, half of which is paid by the company and the other half is paid for by the local regional education association (REA).  Each week, the teacher participants must submit a weekly written reflection. This assignment gives the teachers an opportunity to reflect on what they learned during the week and how it will help them become a more effective teacher. It also provides documentation of their experience that can be included in their final

Lipman2 defines critical thinking as “skillful, responsible thinkingthat facilitates good engineering judgment because it relies upon criteria, is self-correcting, andis sensitive to content.” The EFFECT framework is designed on the basis of this definition.EFFECTs begin with a driving question that is embedded in a decision worksheet

Ethics is a key part of this complexity and the next generation of STEM professionals will need the skills to effectively engage the ethical chal- lenges they will face. Burgess is a regular presenter on incorporating ethics in a K-12 setting. A theme throughout these roles is the importance of teaching ethics and promoting ethical reflection in a way that is both accessible and substantive. This is a challenge that Burgess is keenly interested in.

The TPD can provideopportunities for discussion, reflection, and debate.6 In the same way, groups of teachers couldpose a negative influence on the effort if they do not see the value of the content being learned.Van Driel, Beijaard and Verloop13 found that science teaching reform efforts were largelyineffective in a number of countries, largely due to a failure of the TPD program to

Step 3.3 is designedto get students to articulate their understandings of 3-D objects in terms of geometric shapecharacteristics. Step 5.3 asks students to contemplate their proposed design for the communitycenter by prompting a discussion of shape nets and reflection on students’ designs. Step 7.5requires students to determine, from a list of 3-D shapes, which will roll best, and provide ajustification.

As shown in Figure 2, the challenge basedlearning process begins with a big idea and cascades to the following: an essential question, achallenge, guiding questions, activities, team projects, determining and articulating the solution,taking action by implementing the solution, reflection, assessment, and presentation. Whenusing this pedagogy, the teacher’s primary role shifts from dispensing information to guiding theconstruction of knowledge by his or her students around initially defined guiding questions.Students refine the problem, develop research questions, investigate the topic, and work out avariety of solutions before finding the most reasonable one.

So, indicators thathave the potential to have positive implications for girls to make decisions about engineering areincorrectly perceived as barriers, and many times, girls do not give STEM a chance.

Indicators to assess the quality of TPD can be professional developmentdesign, delivery, content, context, and outcomes11. For example, Kwakman (2003)12 investigatedthe factors that influenced teachers’ participation in TPD by using surveys and reformulating theTPD activities in response to a qualitative study. Duncan, Diefes-Dux, and Gentry (2011)4focused on the content of engineering TPD on teachers’ recognition and understanding of thenature of engineering by coding teachers’ reflective pre- and post-journal responses.

., “What’swho’s your favorite pop singer?” Messing around is the term used to describe interactions withtechnology for the purpose of informally seeking information of interest to the individual. In thechat logs, this was represented by quotes such as “What do you know about penguins?” Finally,geeking out describes interactions with technology that are specifically directed towardsincreasing individual expertise and knowledge of a particular subject area of interest. This wouldbe reflected in the chat logs by quotes such as “Our penguin (-shaped ice cube) did better whenwe used cotton balls to insulate.” The HOMAGO framework is descriptive in nature; thus, its usewas analytical in nature as we looked for learning as driven by the appropriation of

Theseparticular reasons do reflect a lack of interest in the activity; students may have the desire to join,but for one reason or another, they are unable to stay after school and participate. By integratingthe informal activity with the formal classroom environment, these otherwise unreached studentscan benefit from the program.

Batsare nocturnal and consequently work under very low light conditions. By using echolocation,they have the advantage of being able to detect their surroundings even in the dark. Like bats, Page 23.329.6whales and dolphins also operate in low light conditions due to their inability to follow normalsleep cycles like most mammalian species on land because of their need to consciously breathe.Specifically, dolphins and whales stay underwater for long
