Will More Prominent Colleges Abandon the SAT? | MindShift

Approximate Reading Time: < 1 minute

Are we finally starting to move away from standardized, high stakes testing?

“Standardized test scores add remarkably little to our ability to predict a student’s success beyond what their high school GPA and course schedule already tell us,” Maguire claims. “We believe our new test optional policy better aligns with our holistic and careful reviews of student applications. We also believe the policy will encourage more students to consider Ithaca College and help further diversify our applicant pool.”

“They’re incredibly imprecise,” says FairTest spokesman Robert Schaeffer. “They under-predict for women and over-predict for men, for example. And they’re highly coachable, which gives kids who are already likely to do well another leg up.”

  • The implication? Parents and teachers should choose basic e-books like the Kindle or Nook over enhanced e-books, such as the iPad, if they want a more literacy-focused co-reading experience with children. Prompting kids with questions that relate to the text, labeling and naming objects, and encouraging kids to talk about the book’s content from their own perspective all elicit kids to be more verbal, and can lead to improved vocabulary and language development, the study states.

    But if “engagement” is the objective, the issue gets murkier. When it came time to measuring “child-book” engagement, based on the child’s direct attention and touch, more kids showed higher levels of engagement for the e-books than the print books, though a majority were equally engaged by both book types. Children also physically interacted with the enhanced e-book more than when reading either the print or basic e-book.

  • Matt and colleagues found no significant differences in academic outcomes between the two conditions: students in both courses did equally well in terms of grades, pass rates, and standardized measures of statistics knowledge. This falls in line with many, many other studies that have showed no difference in student outcomes between online (or distance) and face to face courses, and the website No Significant Differences is a good place to explore this research.

    It’s not just that the hybrid course is just as good though; it also took less time from teachers and students. The kids in the hybrid condition had 2 fewer hours of class per week (although they apparently spent an extra 30 minutes per week outside of class). Students learned the same amount with less time investment from students and much less investment in faculty. Its exciting to imagine how gaining efficiencies in certain courses could help students finish school faster and learn more and help universities allocate more resources to more complicated learning tasks. In the radio interview, we discuss more about what this means, how it would not apply to all subjects or learning goals, and why the results are promising.

    Despite many Australians now working more than eight hours each day, productivity had not grown over the past decade.

    Highly productive workers spent two-thirds of their time on meaningful work, they took longer breaks, spent less time travelling to work and allocated more time to leisure and recreation.

Global Edmonton | Student gets a zero: Teacher gets suspended

Approximate Reading Time: < 1 minute

via Global Edmonton | Student gets a zero: Teacher gets suspended.

Formal education takes another giant leap towards irrelevancy:

EDMONTON – A teacher with more than three decades of experience is speaking out after he says he was suspended for giving a student a zero.

Lynden Dorval has been a physics teacher at Ross Sheppard High School for 15 years and a teacher in the Edmonton Public School system for 35 years. Last week, he was suspended indefinitely for what he says was insubordination for disobeying an order not to give zeros to students.

“My prinicipal has been giving me directive for almost a year-and-a-half to not give students zeros if they don’t hand in work or show up to write an exam,” Dorval tells Global News. “Instead we have a comment policy where we’re supposed to put in comments indicating what they haven’t done. The problem with that is the marks program doesn’t count that for anything, so if a student had only done half the work then their average mark would be based only on that half the work. The average is calculated by whatever marks are in there.”

This sounds suspiciously like the work of a bully.

via What do non-programming designers have to know? | Janet H. Murray’s Blog on Inventing the Medium.

Exactly!!!

What should she know instead? Key concepts of computational architecture like these:

Information abstraction: Is data separate from proprietary code and stored in a standardized format i.e. in an XML file or a SQL data base rather than in Flash? It is semantically segmented so it can be accessed at multiple granularities?

Modularity: Is the display of the program separate from the data and from any other complex calculations? Will the owners be able to display it on multiple platforms or move it when the current platform becomes obsolete?

Encapsulation: Are the computational structures embedded within one another like Russian dolls, so that you don’t have to recode every layer when you make a change to one of them? Can you reuse the same routines, and especially can you reuse routines for common functions e.g. draw a tree diagram by drawing on other people’s functions like a Java library?Understanding these concepts are much more important for designers than learning the syntax of any particular programming environment.

Visual ability predicts a computer science career: Why? And can we use that to improve learning? « Computing Education Blog

Approximate Reading Time: < 1 minute

This is interesting, and may explain why teachers have trouble with science and math (and why kids who are inclined towards science and math have trouble with teachers).

This is from a longitudinal study, testing students’ visual ability, then tracking what fields they go into later. Having significant visual ability most strongly predicts an Engineering career, but in second place (and really close) is “Mathematics and Computer Science.” That score at the bottom is worth noting: Having significant visual ability is negatively correlated with going into Education. Nora points out that this is a significant problem. Visual skills are not fixed. Training in visual skills improves those skills, and the effect is durable and transferable. But, the researchers at SILC found that teachers with low visual skills had more anxiety about teaching visual skills, and those teachers depressed the impact on their students. A key part of Nora’s talk was showing how the gender gap in visual skills can be easily reduced with training (relating to the earlier discussion about intelligence), such that women perform just as well as men.

Computational Literacy and Literacy vs. Competency

Approximate Reading Time: 2 minutes

The comment about competency vs literacy is a really good one.

So I’ll end with a caution about relying on the word literacy. It’s a word I’m deeply troubled by, loaded with historical and social baggage and it’s often misused as a gatekeeping concept, an either/or state; one is either literate or illiterate.

In my own teaching and research I’ve replaced my use of literacy with the idea of competency. I’m influenced here by the way teachers of a foreign language want their students to use language when they study abroad. They don’t use terms like literacy or fluency, they talk about competency. Because the thing with competency is, it’s highly contextualized, situated, and fluid. Competency means knowing the things that are required in order to do the other things you need to do. It’s not the same for everyone, and it varies by place, time, and circumstance.

via » 5 BASIC STATEMENTS ON COMPUTATIONAL LITERACY SAMPLE REALITY.

Here’s a summary of the 5, along with the take-aways:

  1. 10 PRINT 2+3

    1. Code CAN be obvious – assuming, of course, you understand the fundamentals of computer languages. If you don’t, you will be routinely mistaken. It’s those fundamentals people need to learn when they learn programming, not the picayune details of the specific language they are using this minute.
  2. 10 PRINT “HELLO WORLD”

    1. Communicating with the “outside world” is an important thing to understand.
  3. 10 PRINT “GO TO STATEMENT CONSIDERED HARMFUL”: GOTO 10

    1. “Programming is a set of practices, with its own history and tensions. ” Discipline is important.
  4. 10 REM PRINT “GOODBYE CRUEL WORLD”

    1. “Yes, code does what it says. But it also says things it does not do. ” Also, annotation is important.
  5. 10 PRINT CHR$(205.5+RND(1));:GOTO 10

    1. “There’s a limit to the usefulness of the concept of literacy when talking about code.”

Looks great. Basically a picture book. You’d think that for the price ($13.99) it would be more interactive and that it would include everything one would normally need from a table of elements – like the ion charge, for instance. It’s not like they have to invent this information. For this price, I should not have to buy another app (or book) just to look up facts.

This is one of the classic examples of what I see as a disturbing trend – HD. Don’t get me wrong – I love clear, crisp pictures. What I DON’T like is having to run updates as overnight jobs because they are so bloated that they take forever to download.
