There is a lively debate among politicians and professors about whether the economy is becoming more polarized and about the importance of education. Dismissing the value of a college education is one of the more popular clever-sounding contrarian ideas of the moment. And there are still a few die-hards who play down the social significance of rising income inequality.

When you translate these abstract arguments into the practical choices we make in our personal lives, however, the intellectual disagreements melt away. We are all spending a lot more money to educate our kids, and the richest have stepped up their spending more than everyone else.

spending on children grew over the past four decades and that it became more unequal. “Our findings also show that investment grew more unequal over the study period: parents near the top of the income distribution spent more in real dollars near the end of the 2000s than in the early 1970s, and the gap in spending between rich and poor grew.”

But it turns out that the children being primed for that race to the top from preschool onward aren’t in such great shape, either.

“What we are finding again and again, in upper-middle-class school districts, is the proportion who are struggling are significantly higher than in normative samples,” she said. “Upper-middle-class kids are an at-risk group.”

troubled rich kids. “I was looking for a comparison group for the inner-city kids,” Dr. Luthar told me. “And we happened to find that substance use, depression and anxiety, particularly among the girls, were much higher than among inner-city kids.”

“I Can, Therefore I Must: Fragility in the Upper Middle Class,” and it describes a world in which the opportunities, and therefore the demands, for upper-middle-class children are infinite.

“It is an endless cycle, starting from kindergarten,” Dr. Luthar said. “The difficulty is that you have these enrichment activities. It is almost as if, if you have the opportunity, you must avail yourself of it. The pressure is enormous.”

these parents and children are responding rationally to a hyper-competitive world economy.

“When we talk to youngsters now, when they set goals for themselves, they want to match up to at least what their parents have achieved, and that is harder to do.”

we live in individualistic democracies whose credo is that anyone can be a winner if she tries. But we are also subject to increasingly fierce winner-take-all forces, which means the winners’ circle is ever smaller, and the value of winning is ever higher.

predominant mode of literacy depends on the technology and mass media it embraces (Sinatra, 1986).

Online learning allows for flexibility of access, from anywhere and usually at anytime—essentially, it allows participants to collapse time and space (Cole, 2000)—however, the learning materials must be designed properly to engage the learner and promote learning.

Cognitive psychology claims that learning involves the use of memory, motivation, and thinking, and that reflection plays an important part in learning.

The development of effective online learning materials should be based on proven and sound learning theories.

Early computer learning systems were designed based on a behaviorist approach to learning. The behaviorist school of thought, influenced by Thorndike (1913), Pavlov (1927), and Skinner (1974), postulates that learning is a change in observable behavior caused by external stimuli in the environment (Skinner, 1974).

Therefore, before any learning materials are developed, educators must, tacitly or explicitly, know the principles of learning and how students learn.

Constructivist theorists claim that learners interpret information and the world according to their personal reality, and that they learn by observation, processing, and interpretation, and then personalize the information into personal knowledge (Cooper, 1993; Wilson, 1997).

The design of online learning materials can include principles from all three. According to Ertmer and Newby (1993), the three schools of thought can in fact be used as a taxonomy for learning. Behaviorists' strategies can be used to teach the “what” (facts), cognitive strategies can be used to teach the “how” (processes and principles), and constructivist strategies can be used to teach the “why” (higher level thinking that promotes personal meaning and situated and contextual learning).

The behaviorist school sees the mind as a “black box,” in the sense that a response to a stimulus can be observed quantitatively, totally ignoring the effect of thought processes occurring in the mind.

Learners should be told the explicit outcomes of the learning so that they can set expectations and can judge for themselves whether or not they have achieved the outcome of the online lesson. 2.  Learners must be tested to determine whether or not they have achieved the learning outcome. Online testing or other forms of testing and assessment should be integrated into the learning sequence to check the learner's achievement level and to provide appropriate feedback. 3.  Learning materials must be sequenced appropriately to promote learning. The sequencing could take the form of simple to complex, known to unknown, and knowledge to application. 4.  Learners must be provided with feedback so that they can monitor how they are doing and take corrective action if required.

Cognitivists see learning as an internal process that involves memory, thinking, reflection, abstraction, motivation, and meta-cognition.

Online instruction must use strategies to allow learners to attend to the learning materials so that they can be transferred from the senses to the sensory store and then to working memory.

Online learning strategies must present the materials and use strategies to enable students to process the materials efficiently.

information should be organized or chunked in pieces of appropriate size to facilitate processing.

Use advance organizers to activate an existing cognitive structure or to provide the information to incorporate the details of the lesson (Ausubel, 1960).

Use pre-instructional questions to set expectations and to activate the learners' existing knowledge structure.

Use prerequisite test questions to activate the prerequisite knowledge structure required for learning the new materials.

To facilitate deep processing, learners should be asked to generate the information maps during the learning process or as a summary activity after the lesson (Bonk & Reynolds, 1997).

The cognitive school recognizes the importance of individual differences, and of including a variety of learning strategies in online instruction to accommodate those differences

The Kolb Learning Style Inventory (LSI) (Kolb, 1984) looks at how learners perceive and process information, whereas the Myers-Briggs Type Indicator (Myers, 1978) uses dichotomous scales to measure extroversion versus introversion, sensing versus intuition, thinking versus feeling, and judging versus perception. In the following discussion, we consider the Kolb Learning Style Inventory.

Attention: Capture the learners' attention at the start of the lesson and maintain it throughout the lesson. The online learning materials must include an activity at the start of the learning session to connect with the learners. Relevance: Inform learners of the importance of the lesson and how taking the lesson could benefit them. Strategies could include describing how learners will benefit from taking the lesson, and how they can use what they learn in real-life situations. This strategy helps to contextualize the learning and make it more meaningful, thereby maintaining interest throughout the learning session. Confidence: Use strategies such as designing for success and informing learners of the lesson expectations. Design for success by sequencing from simple to complex, or known to unknown, and use a competency-based approach where learners are given the opportunity to use different strategies to complete the lesson. Inform learners of the lesson outcome and provide ongoing encouragement to complete the lesson. Satisfaction: Provide feedback on performance and allow learners to apply what they learn in real-life situations. Learners like to know how they are doing, and they like to contextualize what they are learning by applying the information in real life.

Online strategies that facilitate the transfer of learning should be used to encourage application in different and real-life situations.

Constructivists see learners as being active rather than passive.

it is the individual learner's interpretation and processing of what is received through the senses that creates knowledge.

“the process of using a prior interpretation to construe a new or revised interpretation of the meaning of one's experience in order to guide future action” (p. 12).

Learning should be an active process. Keeping learners active doing meaningful activities results in high-level processing, which facilitates the creation of personalized meaning. Asking learners to apply the information in a practical situation is an active process, and facilitates personal interpretation and relevance.

Learners should construct their own knowledge rather than accepting that given by the instructor.

Collaborative and cooperative learning should be encouraged to facilitate constructivist learning (H

When assigning learners for group work, membership should be based on the expertise level and learning style of individual group members, so that individual team members can benefit from one another's strengths.

  Learners should be given control of the learning process

Learners should be given time and opportunity to reflect.

Learning should be made meaningful for learners. The learning materials should include examples that relate to students, so that they can make sense of the information.

Learning should be interactive to promote higher-level learning and social presence, and to help develop personal meaning. According to Heinich et al. (2002), learning is the development of new knowledge, skills, and attitudes as the learner interacts with information and the environment. Interaction is also critical to creating a sense of presence and a sense of community for online learners, and to promoting transformational learning (Murphy & Cifuentes, 2001). Learners receive the learning materials through the technology, process the information, and then personalize and contextualize the information.

Behaviorist strategies can be used to teach the facts (what); cognitivist strategies to teach the principles and processes (how); and constructivist strategies to teach the real-life and personal applications and contextual learning. There is a shift toward constructive learning, in which learners are given the opportunity to construct their own meaning from the information presented during the online sessions. The use of learning objects to promote flexibility and reuse of online materials to meet the needs of individual learners will become more common in the future. Online learning materials will be designed in small coherent segments, so that they can be redesigned for different learners and different contexts. Finally, online learning will be increasingly diverse to respond to different learning cultures, styles, and motivations.

Online instruction occurs when learners use the Web to go through the sequence of instruction, to complete the learning activities, and to achieve learning outcomes and objectives (Ally, 2002; Ritchie & Hoffman, 1997).

For younger students, I think that the ability to make something professional-looking, like a real grown-up would, is paramount.  Sadly, I think this means that LOGO and BASIC aren't much use any more*.

So, we have a few choices.  You can try to write phone apps that look just like real phone apps, design interactive websites that look just like real interactive websites, or do something with embedded systems / robotics.  Avoid the temptation to make these things into group projects; the main thing every student needs to experience is the process of writing code, running it, debugging it, and watching the machine react to every command.

It is important to consider what an 11 to 18-year old is familiar with in terms of mathematics and logical thinking. An average 11-year old is probably learning about fractions, simple cartesian geometry, the concept of units, and mathematical expressions. By 15, the average student will be taking algebra, and hopefully will have the all-important concept of variables under his/her belt. So much in CS is dependent on solid understanding that symbols and tokens can represent abstract concepts, values, or algorithms. Without it, it's still possible to teach CS, but it must be done in a very different way (see Scratch).

At this point, concepts such as variables, parenthesis matching, and functions (of the mathematical variety) are within easy reach. Concepts like parameter passing, strings and collections, and program flow should be teachable. More advanced concepts such as recursion, references and pointers, certain data structures, and big-O may be very difficult to teach without first going through some more foundational math.

The key is that the concepts in CS aren't just there for the hell of it. Everything was motivated by a real problem, and few things are more satisfying than fixing something you really want to work with a cool technique or concept you just learned.
