The Test of Gross Motor Development-2 (TGMD-2) is a standardized test that measures gross motor abilities that develop early in life. The TGMD-2 is designed to assess the gross motor functioning in children aged 3 through 10 years. The TGMD-2 looks at 12 gross motor skills divided into two subtests: 1) Locomotor (run, hop, gallop, leap, horizontal jump, and slide); and 2) Object Control (ball skills such as striking a stationary ball, stationary dribble, catch, kick, overhand throw, underhand roll).
Scoring: The child is given 1 for a pass, 0 for a failed attempt. There are no partial marks. Add the two trials together to get the total Score for each performance criteria. Add the total scores for each criteria to get the Skill score. At the end of each Subtest (Locomotor and Object Control) add up the 6 skill scores to get the Subtest Raw Score. High Scores indicate better performance than low scores.
Validity - the validity of the test refers to the degree to which theory and evidence support the stated aims of the test. The TGMD-2 has proven that it is valid using three criteria: i) Content-Description Validity (content experts); ii) Prediction Validity (correlates well with other tests of similar gross motor abilities); and iii)Construct-Identification Validity (degree to which the underlying traits of a test can be identified).
Reliability - the study of a test's reliability centres on estimating the amount of error associated with its scores. The error variance is reported in terms of a reliability coefficient which in order to be considered reliable should reach at least .70, preferably .90 or above. Sources of error variance and analyzed in relation to the TGMD-2 subtest and quotient scores; there were content sampling, time sampling, and interscorer differences.
Using the video assess the performance and score each fundamental motor skill (FMS) http://www.youtube.com/watch?v=1Sw-0GKzsJw . Calculate the Skill Scores and Subtest Raw Scores (will be provided as an attached file TGMD II Scoresheets-Self.pdf). Comparing your FMS TGMD-2 scores to FMS from other assessors (will be provided as an attached file TGMD2 Observations Fall 2013 for KINE 3340.xlsx). Identify the similarities and/or differences for your scores with those of the group and the experienced rater. What are the reliability issues to be considered?
