Additive effects due to biochar and endophyte application enable soybean to enhance nutrient uptake and modulate nutritional parameters

We studied the effects of hardwood-derived biochar (BC) and the phytohormone-producing endophyte Galactomyces geotrichum WLL1 in soybean (Glycine max (L.) Merr.) with respect to basic, macro- and micronutrient uptakes and assimilations, and their subsequent effects on the regulation of functional amino acids, isoflavones, fatty acid composition, total sugar contents, total phenolic contents, and 1,1-diphenyl-2-picrylhydrazyl (DPPH)-scavenging activity. The assimilation of basic nutrients such as nitrogen was up-regulated, leaving carbon, oxygen, and hydrogen unaffected in BC+G. geotrichum-treated soybean plants. In comparison, the uptakes of macro- and micronutrients fluctuated in the individual or co-application of BC and G. geotrichum in soybean plant organs and rhizospheric substrate. Moreover, the same attribute was recorded for the regulation of functional amino acids, isoflavones, fatty acid composition, total sugar contents, total phenolic contents, and DPPH-scavenging activity. Collectively, these results showed that BC+G. geotrichum-treated soybean yielded better results than did the plants treated with individual applications. It was concluded that BC is an additional nutriment source and that the G. geotrichum acts as a plant biostimulating source and the effects of both are additive towards plant growth promotion. Strategies involving the incorporation of BC and endophytic symbiosis may help achieve eco-friendly agricultural production, thus reducing the excessive use of chemical agents.

Teaching Kindergartners Racial Diversity Through Multicultural Literature: A Case Study in a Kindergarten Classroom in Korea

Research Findings: This qualitative case study examines Korean kindergartners’ literary discussions about racial/cultural diversity during a whole-group read-aloud. Using multiple sources of data, including observations, open-ended interviews, and written materials and children’s artifacts, this study found that (a) the children exhibited a biased attitude toward African characters, and their stereotypical views reflected their allegiance to their social/cultural contexts; (b) literary discussions about race provided the children with valuable opportunities to explore racial diversity, equality, injustice, and freedom; and (c) reading multicultural literature helped the children develop and practice their racial language and literacy skills. Practice or Policy: The findings of the study add several important contributions related to teaching young children multicultural literature. Reading literature should be used to provide a chance to explore real-life problems and critically analyze all of the differences children encounter on a daily basis. Teachers should encourage young children to freely share their views about diverse social issues by creating a space where children feel secure in exchanging different views. In order to create a more supportive literacy surrounding, teachers should understand how profoundly children’s social and cultural environments affect their reading practices.     

The child nobody likes

Disliked children may experience unhappiness, loneliness, and considerable frustration during their early involvement in preschool centers and the early years of school. Teachers of young children, realizing the effects of being disliked on self-esteen and academic, social, and personal growth, must work toward either changing the causes of the problem or attempting to change peer and teacher behaviour toward the disliked child.M.

Facilitating Reading Habits and Creating Peer Culture in Shared Book Reading: An Exploratory Case Study in a Toddler Classroom

Fifteen toddlers (2- to 3-years old, nine boys and six girls) in a university preschool classroom were observed for 7 months while spending time with books during transition time, between story time and lunch. This qualitative case study investigated the ways that teachers can facilitate toddlers’ reading habits by providing literacy opportunities in unstructured learning environments and explored the contexts in which toddlers engage in independent reading activities. The findings of this study show that (1) toddlers can develop literacy through participating in meaning-making activities with peers while reading books together in unstructured environments and (2) toddlers want to read and choose to read in order to satisfy their curiosity, involvement, and social interchange, just as older children do.     

Exploring learning culture in Finnish and South Korean classrooms

The authors aimed to investigate learning culture in classrooms at schools to understand education in Finland and South Korea. For this, Finnish and South Korean university students made observations on classrooms in partner countries and reflected on both education systems based on their own previous experiences (2011–2014). Afterwards, researchers from both countries categorized and thematized the experiences of the participants, and interpreted the main themes to figure out the learning culture in Finland and South Korea. As a result, the learning culture in both countries were characterized into six themes: teacher's autonomy in teaching, authenticity in learning, relationships between teachers and students, learning assessment, student engagement, and student well-being. Noteworthy features of high-performing education were recognized through the observation on the learning culture in both countries.     

Differences in food consumption under intermittent and continuous reinforcement schedules of water delivery: Some implications for schedule-induced behavior

Consumption of food pellets was examined in four water-deprived rats during 1-h sessions in which water was presented once every 30, 60, or 120 sec independently of the rats’ behavior according to three fixed-time (FT) schedules. Correlated with each FT condition was a continuous reinforcement (CRF) control condition in which the rats received, at the start of the session, the number of dipper presentations that were programmed to occur during the corresponding FT condition. During both the FT and CRF conditions, pellets per dipper presentation decreased and food intake rate increased with rate of water presentation, and there was a direct linear relation between log food intake and log water intake. For each of these three measures there was less eating under the FT condition than under the CRF condition, but the difference between the FT and CRF functions decreased at shorter FT values. These data are discussed in terms of the effects of amount of water on food consumption and the principle of temporal summation.     

The role of pre-service teachers’ perceived instrumentality,goal commitment,and motivation in their self-regulation strategies for learning in teacher education courses

This study investigated the influence of pre-service teachers’ (n = 142) perceived endogenous/exogenous instrumentality, goal commitment, and intrinsic/extrinsic motivation on their use of self-regulation strategies (effort regulation, management of time and study environment) for their teacher-education courses. Data were drawn from a customised survey and were statistically analysed using hierarchical multiple regressions. Results demonstrated that pre-service teachers’ endogenous instrumentality was a significant contributor for explaining their use of self-regulation strategies. To facilitate pre-service teachers’ use of self-regulation strategies for learning, our findings suggest that, in addition to having intrinsic motivation for learning in their teacher-education courses, they need to have appropriate understandings of how their current course content connects to their future goals to be teachers in order to promote their use of strategies for self-regulation and learning.     

The Relationship between Phonological Awareness and Early Reading for First Grade Korean Language Learners with Reading Difficulties

This study investigated the differences in four components of phonological awareness (i.e., judgment, deletion, blending, and substitution) and early reading ability across reading levels, and the correlation between phonological awareness (PA) and early reading ability in low and average-achievement groups. 27 students with reading difficulties and 34 students with average reading abilities participated in the study, and all participants were native Korean students in Grade One. The results indicated significant differences between low-achievement and averageachievement groups in PA and early reading measures, which revealed features of Korean phonology as different from English. Furthermore, phonological awareness showed significant positive correlation with both word identification and reading fluency for the low and average-achievement groups. For the low-achievement group, the correlation between phonological awareness and reading fluency was higher than between phonological awareness and word identification.
