Using Interactive Nutrition Modules to Increase Critical Thinking Skills in College Courses

Objective: To understand how the addition of an evidence-based framework to an online nutrition module influences college students’ critical thinking decision making (CT-DM). Design: Students were individually randomized into an intervention group or a control group. The nutrition modules focused on 2 topics related to different types of eating behavior. Students completed a CT-DM activity to generate a score. Participants: College students, between 18 and 24 years old, recruited from introductory nutrition and agriculture science courses at 2 universities. Intervention: Intervention and control received 2 nutrition modules. The intervention added a CT-DM framework that framed the topic as a problem, incorporated activities, and provided scaffolding. Main Outcome Measures: CT-DM was scored using a validated rubric to assess the use of critical thinking skills when making a food-related decision. Green eating and critical thinking disposition were measured. Analysis: Hierarchical linear regression and t tests were used to assess outcomes. Results: A total of 431 students participated (intervention = 203; control = 228). After controlling for university, the intervention group scored significantly higher on CT-DM (18.1 ± 7.6) compared with the control (15.4 ± 8.4); F (3,428) = 14.58, P \u3c .001. Conclusions and Implications: The results show that an evidence-based framework using nutrition topics encourages CT-DM skills. Future higher-education nutrition interventions should use frameworks to enhance student learning

Utilising a cultural–historical analysis to map the historicity of Social Studies, Natural Science and Technology education in the early years

Background: South Africa needs citizens who are morally sound, adaptive to change, technologically innovative and literate in socio-scientific issues. The young child is apparently being prepared for active citizenry through basic “Social Science, Natural Sciences and Technology” education as encapsulated in the South African curriculum. Aim: We foreground a theoretical and analytical framework to map the cultural–historical trajectory of South Africa’s Beginning Knowledge curriculum. Setting: Cultivating citizenship requires that these science subject domains be incorporated in a coherent, well-conceptualised and relevant early childhood curriculum as suggested by international literature. Educators need to be specialists in socio-scientific issues in both the content and pedagogy of these sciences in order to expound the curriculum. Methods: Our newly coined hybridised theoretical framework - the ‘Hybrid CHAT’ - together with an aligned analytical framework enabled us to illuminate the historical subject-didactical genetic development of Beginning Knowledge. An extensive sample of typographical textbooks, artefacts and cultural tools were analysed and interpreted. Results: Beginning Knowledge is afforded limited teaching time. The knowledge, skills and values associated with these science subjects serve to support and strengthen the acquisition of language and mathematics competencies. Currently, Beginning Knowledge does not sufficiently prepare child citizens for the global demands of the 21st century. Conclusion: Hybrid CHAT could invite further studies to place Beginning Knowledge on par with international curricula. This would also align the curriculum with the aspirations for an ideal South African citizenry as well as prepare child citizens to pursue Science and Technology for social development

Characterization of developmental changes during the establishment and progression of pregnancy in viviparous nearshore rockfish (Sebastes spp.) and the determination of patterns of post-natal growth

The rockfish (Sebastes spp) is a long-lived viviparous marine teleost found around the world. The diversity of the genus and the wide range of habitats in which is found make it essential that more is known about the effects various changes in the environment have on its reproduction, development and growth.Ovarian cyclicity proceeded under controlled conditions and recurrent seasonality was observed in fish that had previously spawned in culture. Delayed fertilization indicates that pregnancy is not a prerequisite for broodstock selection. Characterization of development from first cleavage to parturition established convenient indices to identify changes in development associated with different environmental conditions. Experiments performed to further characterize the ontogeny of osmoregulatory development established protocols for in vitro incubation of embryos and revealed that a reduced salinity conferred significant survival and growth advantages as compared to embryos developing within the mother. These results indicate some maternal physiological inhibition of development may occur.Growth patterns of grass (S. rastrelliger) and brown (S. auriculatus) rockfish reared in the laboratory were characterized as was growth of two groups of brown rockfish collected during their first and second year of development. Changes in both weight and length followed a sigmoid curve comprising an early phase of exponential growth transitioning to a phase of exponential decay. The constituent phases of this curve and the combined data over a period of 1083 culture-days were precisely described by the Gompertz equation. This equation also described the growth of young-of - the-year copper rockfish (S. caurinus) with similar accuracy. Validation of the Gompertz equation was achieved by reference to sizes of rockfish raised from birth. The mathematical model precisely depicted growth from birth to sexual maturity. These data may find application in the development of rockfish culture programs and assist fisheries managers in assessing size and age relationships.Overall the findings can be applied to the existing knowledge of the endocrine control of osmoregulation and to the existing body of data on the endocrine control of pregnancy in the rockfish. The protocols developed will facilitate further examination of the effects of changes in environmental conditions on viviparous reproduction
