Preparing Students for Lifelong Learning: A Review of Instructional Features and Teaching Methodologies

Lifelong learning is intentional learning that people engage in throughout their lives for personal and professional fulfillment and to improve the quality of their lives. In today's climate of continual change and innovation, lifelong learning is a critical educational goal. In order to prepare people for lifelong learning, educational opportunities must develop their capacity for self‐direction, metacognitive awareness, and disposition toward lifelong learning. Several instructional features facilitate the development of metacognitive and self‐directed learning skills, and the disposition to lifelong learning: (1) student autonomy, responsibility, and intentionality; (2) intrinsically motivating learning activities; (3) enculturation; (4) discourse and collaboration among learners; and (5) reflection. This article describes and presents examples of how three teaching methodologies—problem‐based learning, intentional learning environments, and cognitive apprenticeship—employ these instructional features.     

Correlation network analysis shows divergent effects of a long-term,high-fat diet and exercise on early stage osteoarthritis phenotypes in mice

Background:Obesity increases knee osteoarthritis(OA) risk through metabolic,inflammatory,and biomechanical factors,but how these systemic and local mediators interact to drive OA pathology is not well understood.We tested the effect of voluntary running exercise after chronic diet-induced obesity on knee OA-related cartilage and bone pathology in mice.We then used a correlation-based network analysis to identify systemic and local factors associated with early-stage knee OA phenotypes among the different diet and exercise groups.Methods:Male C57 BL/6 J mice were fed a defined control(10% kcal fat) or high fat(HF)(60% kcal fat) diet from 6 to 37 weeks of age.At 25 weeks,one-half of the mice from each diet group were housed in cages with running wheels for the remainder of the study.Histology,micro computed tomography,and magnetic resonance imaging were used to evaluate changes in joint tissue structure and OA pathology.These local variables were then compared to systemic metabolic(body mass,body fat,and glucose tolerance),inflammatory(serum adipokines and inflammatory mediators),and functional(mechanical tactile sensitivity and grip strength) outcomes using a correlation-based network analysis.Diet and exercise effects were evaluated by two-way analysis of variance.Results:An HF diet increased the infrapatellar fat pad size and posterior joint osteophytes,and wheel running primarily altered the subchondral cortical and trabecular bone.Neither HF diet nor exercise altered average knee cartilage OA scores compared to control groups.However,the coefficient of variation was≥25% for many outcomes,and some mice in both diet groups developed moderate OA(>33% maximum score).This supported using correlation-based network analyses to identify systemic and local factors associated with early-stage knee OA phenotypes.In wheel-running cohorts,an HF diet reduced the network size compared to the control diet group despite similar running distances,suggesting that diet-induced obesity dampens the effects of exercise on systemic and local OA-related factors.Each of the 4 diet and activity groups showed mostly unique networks of local and systemic factors correlated with early-stage knee OA.Conclusion:Despite minimal group-level effects of chronic diet-induced obesity and voluntary wheel running on knee OA pathology under the current test durations,diet and exercise substantially altered the relationships among systemic and local variables associated with early-stage knee OA.These results suggest that distinct pre-OA phenotypes may exist prior to the development of disease.     

Do we need norms of fitness for children with autistic spectrum condition?

The increasingly sedentary habits of children, and rising obesity levels, are prompting concern for children's future health. Children with autistic spectrum condition (ASC) show a clear trend in this regard. Within school, an understanding of how an individual's fitness compares to age norms is important in order to design appropriate exercise programmes. This study, by Maurice Place, Kathleen Dickinson and Joanna Reynolds, all based at Northumbria University, assessed 100 children with ASC and learning difficulty, and found a wide variation in fitness levels as measured by the Eurofit tests. In addition the measure of cardio‐pulmonary fitness (VO_{2 max}) was generally poor. In boys, body mass index (BMI) showed only a modest correlation with this measure of cardio‐pulmonary fitness, with the results for the girls not being significant. Using a variant of the established BMI calculation did not improve the correlation. To our knowledge this article offers the first set of published Eurofit test results for children with ASC and highlights the generally poor level of cardio‐pulmonary fitness in this group of children.     

Teachers’ beliefs about cues to deception and the ability to detect deceit

This study aimed to test beliefs about cues to deception and the ability to detect lies in a group of teachers with different teaching experience. Their results were compared with the results of non-teachers matched in age and with the results of educational studies and psychology students. Both the beliefs of deception indicators and overall truthfulness assessment did not differ between groups. Teaching experience had no effect on any of the skills tested. In accordance with expectations, the truth bias appeared in both the control group and in the group of teachers.     

Number Knowledge and Young Children’s Ability to Measure Length

Research Findings: In this research we explore the relationship between young children’s number knowledge and their measurement of length. First, we examined 4- to 5-year-olds’ (kindergartners’) understanding of and preference for using standard or nonstandard units to measure length. Second, we investigated whether the following tasks were related to children’s understanding of using standard (i.e., rulers) and nonstandard (i.e., blocks) units to measure length: (a) counting and written number identification knowledge, (b) symbolic or nonsymbolic number magnitude comparison ability, and (c) approximate number line estimation ability. Third, we examined whether understanding these number tasks predicted understanding how to measure length for both standard and nonstandard units. Our results show that young children prefer to use standard units of measurement when given a choice, and some of these children use a ruler correctly. Our results also show an important relationship between children’s understandings of numbers and measurement. Practice or Policy: Given children’s preference for rulers, introducing both nonstandard and standard units in early learning settings concurrently rather than consecutively is recommended for practice.     

Imaginary subjects: school science,indigenous students,and knowledge–power relations

The perspectives of indigenous science learners in developed nations offer an important but frequently overlooked dimension to debates about the nature of science, the science curriculum, and calls from educators to make school science more culturally responsive or ‘relevant’ to students from indigenous or minority groups. In this paper the findings of a study conducted with indigenous Maori children between the ages of 10 and 12 years are discussed. The purpose of the study was to examine the ways that indigenous children in an urban school environment in New Zealand position themselves in relation to school science. Drawing on the work of Basil Bernstein, we argue that although the interplay between emergent cultural identity narratives and the formation of ‘science selves’ is not as yet fully understood, it carries the potential to open a rich seam of learning for indigenous children.     

Perceptual Mapping Software as a Tool for Facilitating School-Based Consultation

Perceptual mapping is a systematic method for collecting, analyzing, and presenting group perceptions that is potentially useful in consultation. With input and feedback from a consultee group, perceptual mapping allows the consultant to capture the group's collective perceptions and display them as an organized image that may foster meaningful understanding of their shared beliefs and serve as a stimulus for discussion and problem solving. Perceptual mapping can give school-based consultants an additional means to bring ideas “to the table” that consultees can clearly conceptualize as originating with them as opposed to the notions of the consultant. The authors illustrate the potential use of and offer support for perceptual mapping as a tool for consultation in schools.     

Conceptions of and early childhood educators’ experiences in early childhood professional development programs: A qualitative metasynthesis

ABSTRACT

Policy makers and early childhood stakeholders across the United States continue to seek policy solutions that improve early educators’ instruction of young children. A primary vehicle for attaining this goal is professional development. This has led to an influx of empirical studies that seek to develop a set of best practices for professional development. While this deductive work is important and informative, it provides limited insight into how professional development is being conceptualized, and how teachers experience, respond to, or learn from these programs. This article begins to address these issues by presenting findings from a qualitative metasynthesis of published peer-reviewed qualitative studies of professional development programs for in-service early educators in the United States. By analyzing, synthesizing, and interpreting these studies, it appears that while such programs may have a positive impact on teachers’ conceptions of practice, there is a need to expand the research literature beyond identifying what works so that it includes studies examining teachers using such practices with children and investigations into teachers’ knowledge of their local teaching and learning communities. This study ends by offering an interpretation of the relationship between these findings and the field of teacher education.
