Enablers and Constraints of STEM Programme Implementation: an External Change Agent Perspective from a National STEM Programme in Finland.

An international need exists for effective programmes that will enhance learners' interest in studies and careers related to science, technology, engineering and mathematics, i.e. STEM. When considering the impact of STEM programmes, it is important to identify what can enable or constrain effective programme implementation. As such, enablers can be systematically supported and constraints tackled to maximise a programme's impact. This study considers a nationwide STEM programme in Finland that involved 450 teachers and their learning communities. The study followed an interpretative paradigm, collecting data through semi-structured interviews and analysed with data-driven thematic analysis. The study participants were 14 external change agents operating between participating learning communities and the national programme administration and, thus, had a valuable overview on how the programme evolved. The most important enablers of effective programme implementation were versatile support, programme flexibility and long-term vision. Two major constraints were limited resources and collaboration challenges. Considering the findings of this study can help design effective STEM programmes by providing various support mechanisms for educators, particularly scaffolding; peer and school administrator support; flexibility to enable embedding activities and adapting programme objectives to participants' everyday work; long-term vision to support both lifelong learning and a continuum between different STEM programmes; sufficient time and economic resources to achieve a long-term impact; and collaboration and networking opportunities at the local, regional, national and international levels.

Co-designing a pedagogical framework and principles for a hybrid STEM learning environment design.

The importance of engaging and effective learning environments for science, technology, engineering and mathematics (STEM) has been internationally recognised. However, no comprehensive pedagogical frameworks exist that support STEM learning environment design. In this study, a pedagogical framework and principles for STEM learning environment design were created based on participatory focus groups involving 10-18-year-old students, teachers, school directors, parents, university students and STEM professionals. Representatives of key stakeholder groups in Belarus, Finland, Germany, Greece and Spain (total n = 132) were invited to focus group discussions in which their wishes related to the pedagogical framework were collected. A second focus group discussion session, engaging the same stakeholder groups (total n = 137), was implemented to validate the framework. A final review for the framework and its design principles was conducted in online focus group sessions, involving 20 experts in curriculum, STEM, educational policy and/or educational technology from all participant countries. The co-designed framework, which is strengthened by the research literature, entails the following design principle categories: (1) General principles, (2) Cross-curricular skills, (3) Ways of teaching and learning, (4) Socio-emotional aspects and (5) Educational compatibility. The design principles created in this study have been employed in developing a hybrid (virtual, physical, formal, non-formal and informal) STEM environment, but they can be employed in any (STEM) learning environment design. Instead of focusing on singular design principles, we recommend considering a wide range of different design principles in order to support multiple ways of teaching and learning and to develop both subject-related and cross-curricular competencies.

Signaled night awakening and its association with social information processing and socio-emotional development across the first two years.

STUDY OBJECTIVES: Night awakening is common in infancy, and some infants continue to have signaled night awakenings throughout early childhood. However, the influence of signaled night awakening on children's social development is less explored. In the present study, longitudinal associations between signaled night awakening, social information processing, and socio-emotional development were measured within the CHILD-SLEEP birth cohort in two groups formed based on parent-reported night awakenings. METHODS: At 8 months, there were 77 infants in the waking group (≥3 awakenings) and 69 infants in the nonwaking group (≤1 awakening). At 8 and 24 months, social information processing was measured as children's attention to neutral and emotional faces, and at 24 months, parent-reported socio-emotional behavior was measured with the Brief Infant-Toddler Social and Emotional Assessment (BITSEA) questionnaire. RESULTS: The two groups showed different patterns of attention to emotional faces. The waking group had a more pronounced attentional bias to fearful versus happy faces, whereas in the nonwaking group, attention to fearful and happy faces did not differ. In addition, at 24 months, the waking group had more dysregulation problems and lower social competence than the nonwaking group, but no clear differences in internalizing or externalizing problems were found. CONCLUSIONS: Our results contribute to the literature by showing that during the first 2 years of life, signaled night awakening is associated with social information processing and socio-emotional behavior.

Exposure to electronic media was negatively associated with speech and language development at 18 and 24 months.

AIM: This study evaluated early speech and language development at 18 and 24 months, and associated factors, based on parental reports. METHOD: We followed up the CHILD-SLEEP birth cohort of 1667 Finnish-speaking families, who were randomly recruited in 2011-2013 during routine visits to maternity clinics in the Pirkanmaa Hospital District of Finland. The women were approximately 32 weeks' pregnant at enrolment. Parents reported the size of their child's expressive vocabulary, word combinations, intelligibility, finger-pointing and adherence to instructions. A subsample was studied using the Expressive Language subscale of the Bayley Scales of Infant and Toddler Development, Third Edition. RESULTS: The children's vocabulary was smaller than previously reported. At 18 months of age, 68.8% of the 997 children had a vocabulary of 20 words or less and 35.7% used about five words at most. At 24 months, 32.4% of the 822 children had a vocabulary of 50 words or less and 18.4% used about 20 words at most. Longer child and parental exposure to electronic media was negatively associated with the size of the child's expressive vocabulary. CONCLUSION: Vocabulary size at 18 and 24 months was smaller than previously reported and negatively associated with exposure to electronic media.

Slow-wave activity and sigma activities are associated with psychomotor development at 8 months of age.

STUDY OBJECTIVES: The electrophysiological properties of non-rapid eye movement sleep (NREM) EEG are homeostatically modulated on global and local use-dependent levels. Furthermore, the local NREM quality reflects age-dependent brain maturation and individual, age-independent, and psychomotor potential. Cortical maturation and its electrophysiological marker, Slow-wave activity (SWA), as well as sleep spindles are known to change in topography and quality during the early years of life, but their associations with psychomotor development in infants are unknown. Therefore, we aimed to evaluate the local properties of SWA and spindles (sigma power) and ascertain whether they correlate with psychomotor development in 8-month-old infants. METHODS: Ambulatory polysomnographies were recorded in 56 infants at 8 months of age to calculate the local SWA and sigma powers. The associations between the SWA and sigma powers and psychomotor development (Bayley-III) were examined in 36 of these infants. RESULTS: In both hemispheres, the highest SWA and sigma powers were found occipitally and centrally, respectively, with higher powers in the right hemisphere than in the left. The Bayley-III correlated with local SWA and sigma powers: the occipital SWA and centro-occipital sigma correlated with cognitive scales, and the frontal and occipital SWA and centro-occipital sigma correlated with language and fine motor scales. Most of the correlations were unilateral. CONCLUSIONS: In 8-month-old infants, the NREM sleep quality shows local differences that are mostly attributable to the topical phase of brain maturation. The local NREM parameters correlate with psychomotor development.

Night Awakening and Its Association With Executive Functioning Across the First Two Years of Life.

Longitudinal associations between signaled night awakening and executive functioning (EF) at 8 and 24 months in children with (≥ 3 awakenings, n = 77) and without parent-rated fragmented sleep (≤ 1 awakening, n = 69) were studied. EF was assessed with the Switch task at 8 and 24 months. At 24 months, behavioral tasks and parental ratings of EF (Behavior Rating Inventory of Executive Function-Preschool version) were also used. In the Switch task, children with fragmented sleep were less able to learn stimulus sequences and inhibit previously learned responses than children without fragmented sleep. The groups differed only marginally in parental ratings of EF, and no differences were found in behavioral EF tasks. These results suggest that eye movement-based measures may reveal associations between sleep and EF already in infancy and toddlerhood.

Night awakening in infancy: Developmental stability and longitudinal associations with psychomotor development.

Fragmented sleep is common in infancy. Although night awakening is known to decrease with age, in some infants night awakening is more persistent and continues into older ages. However, the influence of fragmented sleep on development is poorly known. In the present study, the longitudinal relationship between fragmented sleep and psychomotor development (Bayley Scales of Infant and Toddler Development [Bayley-III]; Bayley, 2009) was investigated in infants with (≥3 night awakenings, n = 81) and without fragmented sleep (≤1 night awakening, n = 70) within the CHILD-SLEEP birth cohort at 8 and 24 months of age. Differences in parent-reported (Brief Infant Sleep Questionnaire [BISQ]) sleep parameters were studied at 8, 18, and 24 months of age. Group differences in night awakening were stable across all assessment points. Infants with fragmented sleep slept less in total than infants without fragmented sleep and they did not compensate their nocturnal sleep during daytime. Additionally, infants with fragmented sleep spent more time awake at night than infants without fragmented sleep. However, psychomotor development did not differ between infants with and without fragmented sleep at 8 or 24 months of age. Our findings indicate that early onset fragmented sleep did not have a negative effect on psychomotor development within the first 2 years despite the differences in sleep length among infants with and without fragmented sleep. In the future, more specific domains of cognitive development and various factors affecting sleep fragmentation should be taken into account when studying the developmental effects of night awakening in infancy.

Respiratory sinus arrhythmia moderates the impact of maternal prenatal anxiety on infant negative affectivity.

Maternal prenatal anxiety is associated with infants' temperamental negative affectivity (NA), but it is unclear to what extent children vary in their susceptibility to prenatal influences. We tested a hypothesis that infants' respiratory sinus arrhythmia (RSA), an index of parasympathetic vagal tone and a potential marker of differential susceptibility to environmental influences, moderates the effects of maternal prenatal anxiety on the development of infant NA. Prenatal anxiety was assessed during the last trimester of pregnancy in a low-risk community sample. Infant NA, baseline RSA, and maternal postnatal anxiety were assessed at 8-10 months of infant age. Regression analyses were performed to predict infant NA on the basis of prenatal anxiety, infant baseline RSA, and their interaction (N = 173). Maternal prenatal anxiety and infant RSA interactively predicted infant NA at 8-10 months. Among infants with high RSA, a significant positive association between prenatal anxiety and infant NA was observed, whereas prenatal anxiety did not predict infant NA among infants with low RSA. Vagal tone, as indexed by baseline RSA, may provide a promising marker of differential susceptibility to the long-term effects of varying intrauterine conditions.

Dry paths effectively reduce road mortality of small and medium-sized terrestrial vertebrates.

Wildlife passages are widely used mitigation measures designed to reduce the adverse impacts of roads on animals. We investigated whether road kills of small and medium-sized terrestrial vertebrates can be reduced by constructing dry paths adjacent to streams that pass under road bridges. The study was carried out in southern Finland during the summer of 2008. We selected ten road bridges with dry paths and ten bridges without them, and an individual dry land reference site for each study bridge on the basis of landscape and traffic features. A total of 307 dead terrestrial vertebrates were identified during the ten-week study period. The presence of dry paths decreased the amount of road-killed terrestrial vertebrates (Poisson GLMM; p < 0.001). That was true also when considering amphibians alone (p < 0.001). The evidence on road-kills on mammals was not such clear. In the mammal model, a lack of dry paths increased the amount of carcasses (p = 0.001) whereas the number of casualties at dry path bridges was comparable with dry land reference sites. A direct comparison of the dead ratios suggests an average efficiency of 79% for the dry paths. When considering amphibians and mammals alone, the computed effectiveness was 88 and 70%, respectively. Our results demonstrate that dry paths under road bridges can effectively reduce road-kills of small and medium-sized terrestrial vertebrates, even without guiding fences. Dry paths seemed to especially benefit amphibians which are a threatened species group worldwide and known to suffer high traffic mortality.

Autonomic arousal to direct gaze correlates with social impairments among children with ASD.

The present study investigated whether autonomic arousal to direct gaze is related to social impairments among children with autism spectrum disorder (ASD). Arousal was measured through skin conductance responses (SCR) while the participants (15 children with ASD and 16 control children) viewed a live face of another person. Impairments in social skills was assessed with the Developmental, Dimensional and Diagnostic Interview. The level of arousal enhancement to direct gaze in comparison to arousal to faces with averted gaze or closed eyes was positively associated with impairments in social skills (use of language and other social communication skills and use of gesture and non-verbal play) among children with ASD. There was no similar association among children without ASD. The role of arousal-related factors in influencing eye contact behaviour in ASD is discussed.

Rural-urban differences in health and health behaviour: a baseline description of a community health-promotion programme for the elderly.

STUDY OBJECTIVE: To (1) describe the setting and design of the Good Ageing in Lahti Region (GOAL) programme; (2) by using the baseline results of the GOAL cohort study, to examine whether living in urban, semi-urban, or rural communities is related to risk factors for chronic diseases and functional disability in ageing individuals. DESIGN: The baseline data of a cohort study of ageing individuals living in three community types (urban, semi-urban, rural). Data were collected by two questionnaires and laboratory assessments. SETTING: Fourteen municipalities in the Lahti region (Päijät-Häme County) in Finland. PARTICIPANTS: A regionally and locally stratified random sample of men and women born in 1946-50, 1936-40, and 1926-30. A total of 4,272 were invited and 2,815 (66%) participated. MAIN RESULTS: Elevated serum cholesterol, obesity, disability, sedentary lifestyle (<2 times/week walking), and high fat intake were more prevalent in rural vs. urban and semi-urban communities. After adjustment for sex, age, education, obesity, diet, physical activity, smoking, and alcohol use, rural communities remained the only community type with increased (p<0.05) probability for high BMI (OR 1.33) and high waist circumference (OR 1.43). CONCLUSIONS: The unfavourable health and lifestyle profile, together with an old population, makes health promotion for elderly citizens a special challenge for rural communities such as those in Päijät-Häme County, Finland. Most, if not all, of the differences in health between the three community types were explained by educational background, physical activity, and smoking.
