    Learner-Centered Nature Walks details the research of Heather van der Grinten in supplementing Junior Ranger Walks with a learner-centered mindset. The approach was intended to reflect her personal growth as a museum educator, demonstrate the viability of the Bank Street praxis of progressive education in an environmental education setting, and highlight potential growth for future Junior Ranger lesson-planning. The methodology involved experimenting with lesson plans, keeping a detailed reflection journal, and asking for voluntary feedback from peers, supervisors, and participants from June to September 2018. The samples of student work as shown in Appendix A and B were voluntarily given to van der Grinten to be used as part of her analysis. The research has found that asking for input as an initiation to an experience creates an immediate sense of engagement on the part of the participants. The research also concluded that inviting learners to create a visual artifact after a direct sensory experience provided an opportunity for reflection, group discussion, and an informal evaluation tool for the educator to monitor the program’s effectiveness. These findings support the ideal conclusion of a Junior Ranger Walk – an empowered youth who has the skill and desire to engage meaningfully in public lands

    A genotype-first approach identifies an intellectual disability-overweight syndrome caused by PHIP haploinsufficiency

    Genotype-first combined with reverse phenotyping has shown to be a powerful tool in human genetics, especially in the era of next generation sequencing. This combines the identification of individuals with mutations in the same gene and linking these to consistent (endo)phenotypes to establish disease causality. We have performed a MIP (molecular inversion probe)-based targeted re-sequencing study in 3,275 individuals with intellectual disability (ID) to facilitate a genotype-first approach for 24 genes previously implicated in ID.Combining our data with data from a publicly available database, we confirmed 11 of these 24 genes to be relevant for ID. Amongst these, PHIP was shown to have an enrichment of disruptive mutations in the individuals with ID (5 out of 3,275). Through international collaboration, we identified a total of 23 individuals with PHIP mutations and elucidated the associated phenotype. Remarkably, all 23 individuals had developmental delay/ID and the majority were overweight or obese. Other features comprised behavioral problems (hyperactivity, aggression, features of autism and/or mood disorder) and dysmorphisms (full eyebrows and/or synophrys, upturned nose, large ears and tapering fingers). Interestingly, PHIP encodes two protein-isoforms, PHIP/DCAF14 and NDRP, each involved in neurodevelopmental processes, including E3 ubiquitination and neuronal differentiation. Detailed genotype-phenotype analysis points towards haploinsufficiency of PHIP/DCAF14, and not NDRP, as the underlying cause of the phenotype.Thus, we demonstrated the use of large scale re-sequencing by MIPs, followed by reverse phenotyping, as a constructive approach to verify candidate disease genes and identify novel syndromes, highlighted by PHIP haploinsufficiency causing an ID-overweight syndrome.status: publishe
