Intellectual Demand
What does this really mean?

intelligence

uni entry score
knowledge
(instructable)
(instructable)
procedural
know-how
"fluency"
(not instructable but learnable)
putting it all
view of self as
a learner
(not instructable but learnable)
into action
not reading
not more/better "instruction"
"...but I've taught them that!"

“… those children who became more
self-controlled from childhood to young adulthood had better outcomes by the age of 32 y, even after controlling for their initial levels of childhood self-control.”

For example

e.g., Stankov et al. (2012) Learning & Individual Differences
"Confidence: a better predictor of academic achievement thank self-efficacy, self-concept and anxiety?"
e.g., Raemdonck, et al. (2011) Vocations & Learning
"Does self-directedness in learning and careers predict the employability of low qualified employees."
From Westwell & Panizzon (2011)

"… For those with the capacity to take advantage of these changes, typically the affluent, expanding opportunities led to improved outcomes. But for those without, events left them further behind than ever.”

not throwing away - getting a more complete view
first step to meaningful Intellectual Demand
(but not the last)
1. understand the problem


2. devise a plan


3. carry out the plan

4. look back
SEARCH - underline the question
SORT - identify relevant information

SEE - visualise, draw a diagram/map
SELECT - decide what are you going to use

SOLVE - use your knowledge & information

SENSE - does it make sense?

APPLICATIONS
The teacher explains how a school science idea can be applied to a number of different phenomena (e.g.,the movement of objects, substances with similar properties)
The teacher uses science to help students understand the world outside school
The teacher clearly explains the relevance of broad science concepts to our lives
The teacher uses examples of technological application to show how school science is relevant to society
HANDS_ON
Students are required to design how a school science question could be investigated in the laboratory
Students spend time in the laboratory doing practical experiments
Students do experiments by following the instructions of the teacher
Students are asked to draw conclusions from an experiment they have conducted
INTERACTION
The lesson involved students' opinions about the topics
Students are given opportunities to explain their ideas
There is a class debate or discussion
INVESTIGATION
Students are given the chance to choose their own investigations
Students are allowed to design their own experiments
Students are asked to do an investigation to test out their own ideas

Instead, students should conduct investigations with appropriate guidance and instructional scaffolding. Finally, making science relevant seems important for student’s achievement, as captured by the positive link between models and applications in science (APPLICATIONS) and science achievement."
"... our analyses clearly indicate that there are particular pedagogical approaches underlying inquiry that appear to be more influential on student’s achievement in science."
"Overall, our findings do not imply that scientific investigations are not valuable to students’ learning of science and their science achievement.
However, the evidence seems to strongly suggest that students who independently select and carry out such investigations tend to have lowered science achievement.
...such investigations may lack proper instructional scaffolding.

...investigations, in of themselves, are not effective, particularly if students are left to discovery processes on their own...

Does this word

Does this word
have an e?
EFs and prefrontal cortex are the first to suffer, and suffer disproportionately, if something is not right in your life. They suffer first, and most, if you are:
stressed,
sad,
lonely,
sleep deprived,
or not physically fit
(Arnsten 1998, Liston et al. 2009, Oaten & Cheng 2005)
(Hirtetal. 2008, von Hecker & Meiser 2005)
(Baumeister et al. 2002, Cacioppo & Patrick 2008, Campbell et al. 2006, Tunet al. 2012)
(Barnes et al. 2012, Huang et al. 2007)
(Best 2010, Chaddock et al. 2011, Hillman et al. 2008).
Any of these can cause you to appear to have a disorder of EFs, such as ADHD, when you do not.

You can see the deleterious effects of stress, sadness, loneliness, and lack of physical health or fitness at the physiological and neuroanatomical level in prefrontal cortex and at the behavioural level in worse EFs (poorer reasoning and problem solving, forgetting things, and impaired ability to exercise discipline and self control).
