Wechsler Intelligence Scale for Children (WISC)

Audio Transcript Auto-generated

• 00:02 - 00:06

  So we, um, had Wexler's intelligence scale for Children.

• 00:07 - 00:08

  The w i sc.

• 00:09 - 00:11

  Um, this is a performance assessment.

• 00:13 - 00:15

  Um, and you'll learn we're gonna talk a little bit

• 00:15 - 00:17

  about what it measures.

• 00:19 - 00:20

  So what is the w i S e.

• 00:21 - 00:24

  It is the obviously intelligence scale for Children.

• 00:25 - 00:28

  We're gonna be talking about what it is, um, who

• 00:28 - 00:31

  is given to the parts and the reliability and validity.

• 00:36 - 00:40

  It is actually an assessment of academic achievement typically given

• 00:41 - 00:44

  to Children between the ages of six and 16.

• 00:46 - 00:48

  It's used for an intelligence test.

• 00:49 - 00:52

  Um, and it's in its fifth edition, which is the

• 00:52 - 00:53

  most recent version.

• 00:54 - 00:58

  It typically takes 45 to 65 minutes.

• 00:58 - 01:02

  Um, and it's what we would know as tthe e

• 01:02 - 01:07

  full scale i Q or the intelligence quotient of a

• 01:07 - 01:08

  child's abilities.

• 01:13 - 01:16

  So some of the measures and constructs of this test

• 01:17 - 01:18

  the way it scored is it's made up of 10

• 01:19 - 01:22

  sub tests with five scores to use to calculate the

• 01:22 - 01:25

  full, like you were going to talk about that in

• 01:25 - 01:25

  a second.

• 01:26 - 01:29

  But the full version of this actually has 15 sub

• 01:30 - 01:34

  tests which, um, Onley 10 are considered the core of

• 01:34 - 01:38

  it, so they actually narrow it down to from 10

• 01:38 - 01:38

  to 5.

• 01:39 - 01:43

  But it actually the full version of this has 15.

• 01:47 - 01:54

  So, um, this actually it was constructed to look at

• 01:54 - 01:59

  reading, X reading, written expression, math, listening comprehension and Orel

• 02:00 - 02:04

  expression. Um, as well.

• 02:04 - 02:07

  So, like, this is kind of like the broken down

• 02:07 - 02:12

  terms from what you'll see in just a second eso

• 02:12 - 02:17

  It measures the intellectual functioning of verbal comprehension, perceptual reasoning,

• 02:17 - 02:19

  working memory, processing speed.

• 02:21 - 02:24

  And then it goes in those categories, actually, go ahead

• 02:24 - 02:28

  and provide the scores for the Verbal Comprehension Index, the

• 02:28 - 02:32

  Perceptual Reasoning Index and the working memory indexed and PS

• 02:33 - 02:38

  I. So those obviously are taken, and then they're broken

• 02:38 - 02:46

  down further to give you those scores for the reliability

• 02:47 - 02:47

  for this test.

• 02:48 - 02:49

  It actually was quite good.

• 02:50 - 02:52

  Um, the scale reliability was examined.

• 02:53 - 02:56

  I'm using test retest and split half methods.

• 02:58 - 03:02

  Um, the reliability coefficients were really good.

• 03:03 - 03:05

  Adequate to very good, as we can see.

• 03:06 - 03:14

  And the test retest coefficients showed that they, um, that

• 03:14 - 03:17

  they were all like sub skills.

• 03:18 - 03:23

  Um, except picture concepts were adequate to very good, too.

• 03:24 - 03:27

  So all in all, it was quite reliable.

• 03:28 - 03:31

  It was determined that it was quite reliable by this

• 03:32 - 03:33

  particular journal in several journals.

• 03:33 - 03:38

  Actually, that we saw, um, after researching this, but this

• 03:38 - 03:42

  isn't was determined AIG AA an adequate to very good

• 03:43 - 03:47

  reliability method in regarding the validity.

• 03:48 - 03:55

  Um, in order to examine that they took the Ravens

• 03:55 - 04:00

  standard progress maitresse ease in the Wechsler The W S

• 04:01 - 04:02

  I s C in 1974.

• 04:04 - 04:06

  Um, and they kind of compared them.

• 04:06 - 04:11

  And they they had the results indicate that there were

• 04:11 - 04:12

  significant correlations.

• 04:13 - 04:18

  So the validity was determined by those two methods.

• 04:19 - 04:22

  Eso That's how we kind of came up with the

• 04:22 - 04:25

  most recent W I s C test.

• 04:27 - 04:32

  Um so in these are some of our sources.

• 04:33 - 04:36

  Oh, I guess one of those didn't say, But we

• 04:37 - 04:40

  will add that, um, it was actually a textbook, as

• 04:40 - 04:42

  we saw in the beginning of the slide.

• 04:43 - 04:46

  So that is our that's actually our classroom textbook and

• 04:47 - 04:50

  paid to 1 67 So that is our test.

• 04:51 - 04:58
