Motor learning difficulties, such as the developmental coordination disorder (DCD), imply substantial difficulties in learning new motor skills. The purpose of this study was to develop an observation tool for teachers to identify motor learning problems. A further aim was to clarify how teachers can support children with motor learning challenges in the school environment. The study consisted of four sub-studies. The first sub-study comprised a systematic literature review on the psychometric properties and usability of the observation forms used internationally. The Dutch Motor Observation Questionnaire for Teachers (MOQ-T) was selected for cross-cultural translation and adaptation. Its translation work and reliability were analysed in the second sub-study. In the third sub-study, the psychometric properties of the Finnish version, MOQ-T-FI were analysed based on a larger set of empirical data. The last sub-study was a descriptive review exploring more closely how motor learning difficulties can be identified and pupils supported in the school environment. The development as well as reliability assessments of the MOQ-T-FI questionnaire were based on five different data sets. The data of pretest 1 consisted of evaluations by 11 teachers (children n = 33, age 6–13, average 9.85). The data of pretest 2 comprised children in eight comprehensive schools (teachers n = 27; children n = 193; age 6–12, average 9.5). The Finnish reference value data for MOQ-T-FI were collected as comprehensively as possible from the various parts of Finland (teachers n = 111; children n = 850; age 6–9, average 7.7). In addition, two complementary data sets not included in the sub-studies were utilised. The studies demonstrated that teachers have good opportunities to identify motor learning difficulties in the school environment. MOQ-T-FI is a functional, simple to use and culturally neutral screening instrument. In terms of validity, it is relatively suitable for identifying pupils’ motor learning difficulties, and for its usability it ...
