Changing Minds With the Story of Adaptation: Strategies for Teaching Young Children About Natural Selection

Research Findings: Educational guidelines recommend a delayed, piecemeal approach to instruction on adaptation by natural selection. This approach is questionable given suggestions that older students’ pervasive misunderstandings about adaptation are rooted in cognitive biases that develop early. In response to this, Kelemen et al. (2014) recently showed that young children can learn a basic yet comprehensive explanation of adaptation by natural selection from a picture storybook intervention. However, this research was conducted in a laboratory-based setting with children from middle and higher socioeconomic backgrounds. To further explore the intervention’s efficacy, this investigation examined whether Kelemen et al.’s (2014, Experiment 2) findings extend to a more diverse sample of children tested in a more naturalistic setting, namely, after-school programs. After a 10-min picture storybook reading that described adaptation within a fictitious but realistic mammal species, 5- to 6- and 7- to 8-year-old children’s learning of adaptation was examined. Results revealed that younger and older children benefitted from the intervention; however, older children displayed pronounced learning and generalization. Practice or Policy: Findings confirm that children are capable of learning complex biological ideas and that comprehensive storybook interventions are simple but powerful teaching tools. Implications for instruction on natural selection are discussed.     

Putting Making into High School Computer Science Classrooms: Promoting Equity in Teaching and Learning with Electronic Textiles in Exploring Computer Science

Recent discussions of making have focused on developing out-of-school makerspaces and activities to provide more equitable and enriching learning opportunities for youth. Yet school classrooms present a unique opportunity to help broaden access, diversify representation, and deepen participation in making. In turning to classrooms, we want to understand the crucial practices that teachers employ in broadening and deepening access to making. In this article, we investigate two high school teachers' approaches in implementing a novel eight-week, electronic textiles unit within the Exploring Computer Science curriculum, where students designed wearable electronic textile projects with microcontrollers, sensors, and LEDs. We share teachers' emergent practices in transforming their classrooms into makerspaces, including valuing student expertise and promoting connections in personalized work. We discuss the ways these practices succeeded in broadening access to making while deepening participation in computing and establishing home-school connections.     

Inside Out or Outside In? On Criteria for Selecting Teachers of Religion,and the Case of the Druze

Abstract

This essay explores the issue of dress of teachers of Druze heritage. The Druze, among whom the rules of religious dress are rather specific, do not teach religion in schools, since the Druze religion is secret. The teacher acts as a gatekeeper and model. At the same time, Druze young people are becoming increasingly secular and may relate better to teachers who appear to be part of the modern world. This discussion examines the role of dress in teacher modeling, and the part Druze teachers may have to play in sustaining a small religion in rapidly changing times.     

Foraging on the radial-arm maze: Effects of altering the reward at a target location

Thirsty rats were trained to collect small water rewards from the end of each arm of an eight-arm radial maze. During these training trials and subsequent testing trials, the subjects were allowed to choose a maximum of eight arms. “Preference” for a target maze location was studied by noting when, in the sequence of eight choices, the target was selected. During testing, when one maze location was consistently devoid of water, rats decreased their preference for this arm over trials (Experiment 1). Similarly, rats that learned a saccharin-lithium association demonstrated lower preferences for a maze location that consistently held the conditioned saccharin solution. This was true for animals that received saccharin-lithium conditioning on the maze (Experiment 3A) and for animals conditioned to saccharin in a separate context (Experiment 3B). An increase in preference for a target maze location consistently containing a sweet chocolate milk solution was observed in animals that were water- and food-deprived (Experiment 2). These studies demonstrate that animals will modify their responses toward (preferences for) maze locations that predictably contain an altered reward.     

Teacher–Child Interactions in Early Head Start Classrooms: Associations With Teacher Characteristics

ABSTRACT

Research Findings: The current study examined characteristics of 71 Early Head Start lead teachers in relation to classroom interactions with infants and toddlers. Measured teacher characteristics included education, years of experience, beliefs about child rearing, depressive symptoms, and the temperamental characteristics of positivity and frustration. Teacher–child interactions were measured using the Classroom Assessment Scoring System, Toddler Version (La Paro, Hamre, & Pianta, 2012). Results indicated that field of degree was directly associated with the majority of dimensions of teacher–child interactions. Examination of teachers’ years of experience and intrapersonal characteristics revealed a number of significant interactions, indicating that teacher experience and appropriate beliefs may serve as protective factors in the presence of psychosocial risk factors. Practice or Policy: Overall, our findings suggest that both early childhood education degrees and years of experience are directly or indirectly associated with multiple dimensions of teacher–child interactions, confirming that these patterns established for preschool teachers hold for teachers of infants and toddlers. These results also suggest that years of experience and progressive beliefs about children may be especially important for teachers who are depressed or who have low levels of positivity and high levels of frustration. Implications for future research, as well as preservice and in-service professional development, are discussed.     

Supplemental reading strategy instruction for adolescents: A randomized trial and follow-up study

In this study, the authors examine the impact of a yearlong supplemental reading course involving daily instruction in the learning strategies curriculum on lower achieving adolescent students' reading achievement and motivation. Using a multiple-cohort randomized treatment-control group design over 4 years, they compared achievement and motivation outcomes for 605 sixth-grade students who participated in the intervention with 530 students who did not participate and 593 ninth-grade students who participated in the intervention with 535 students who did not participate. Results indicated significant impacts of the intervention on reading achievement for ninth-grade students but not for sixth-grade students. Significant impacts on reading motivation were found for both sixth- and ninth-grade students. An exploratory follow-up study indicated potential benefits of a second year of intervention for sixth-grade students who are still low achieving after 1 year of intervention.     

A “Toolkit” for developing critically reflective science teachers

The purpose of this paper is to describe various “tools” we use to facilitate critical reflection as we teach prospective science teachers. The notion of “tools” refers to materials and experiences used to facilitate prospective teachers’ critical reflection on science teaching and learning. Reflective tools are not intrusive devices used by instructors to analyse mechanically what prospective teachers are learning; rather, these tools are intended to provide prospective teachers with the means to generate and critique their own views of science teaching and learning. Each tool is described herein with respect to its potential use and the way in which it is introduced to prospective science teachers. We conclude with discussion of the potential for reflective tools to contribute to research on reform of science teacher education, with particular attention to primary teacher preparation.
