Using scaffolded rubrics to improve peer assessment in a MOOC writing course

This study explored the value of using a guided rubric to enable students participating in a massive open online course in writing to produce more reliable assessments of their fellow students’ writing. To test the assumption that training students to assess will improve their ability to provide quality feedback, a multivariate factorial analysis was used to determine differences in assessments made by students who received guidance on using a rating rubric and those who did not. Although results were mixed, on average students who were provided no guidance in scoring writing samples were less likely to successfully differentiate between novice, intermediate, and advanced writing samples than students who received rubric guidance. Rubric guidance was most beneficial for items that were subjective, technically complex, and likely to be unfamiliar to the student. Items addressing relatively simple and objective constructs were less likely to be improved by rubric guidance.     

Following their companions as a form of exploration for human infants

Infants' following of other persons, often considered a measure of attachment, qualified as a form of exploration. The results of the first experiment indicated that following can be a means of investigating novel leaders: 16 9--12-month-old infants were as likely to follow an unfamiliar woman as they were the parent and were reliably more likely to follow a moving toy. The second and third experiments assessed the extent to which the experience of following familiar persons promotes learning about the environment. Infants who followed their mothers to 1 place were more likely later to investigate a similar place than those who initially either locomoted independently (experiment 2) or were transported by their mothers (experiment 3). The findings suggested that infants' transactions with the environment need not be considered antithetical to their social behavior.     

The Information Content of Employee Awards

Employers often provide awards to employees to induce greater effort. Although a merit award system may increase effort and productivity, it may also produce unintended consequences if it provides new information to the labor market that enables outside employers to differentiate workers more accurately by their effectiveness. In this paper, I present evidence on the signaling effects of merit awards received by school principals in Chicago using regression discontinuity design methods. I find that principals who just exceeded the threshold for a merit award are over twice as likely to exit their school the year after winning compared to principals who fell just short of the award threshold, consistent with the notion that the labor market views the award as a signal of principal effectiveness. Difference-in-differences estimates show that the award program incentives increased achievement, highlighting the importance of program modifications that reduce the loss of more effective school leaders.     

Diet sampling by wild Norway rats offered several unfamiliar foods

The present experiment was undertaken to examine directly the diet sampling behavior of wild Norway rats (Rattus norvegicus) faced with a choice among familiar and unfamiliar foods. First-generation, laboratory-reared wild Norway rats ate from four food cups. Three of the food cups were in unfamiliar locations and contained unfamiliar foods. The remaining food cup was in a familiar location and contained a familiar food. Subjects in a control group were offered the familiar food in all four locations. We found (1) that subjects in experimental and control conditions took equal amounts of time to first visit food cups in unfamiliar locations, (2) that subjects in the experimental condition (those with access to unfamiliar foods) ate at unfamiliar locations at a slower rate than did subjects in the control condition (those with access only to familiar food), (3) that subjects in the experimental condition were no more likely than subjects in the control condition to eat at one unfamiliar location at a time, and (4) that following a bout of eating at an unfamiliar food cup, subjects in the experimental condition waited no longer than subjects in the control condition before eating from a different unfamiliar food cup. We interpreted these data as indicating that although wild Norway rats are hesitant to eat unfamiliar foods, once they begin to eat such foods, they do not sample among them so as to facilitate identification of any toxin present.     

An Inquiry into the Spontaneous Transfer of Problem-Solving Skill

Problem solving, by definition, involves achieving new understanding in unfamiliar contexts, and is critical to all aspects of life, especially in the educational and scientific arenas. Students learn from many experiences to develop a repertoire of abilities, including the use of logic, which enable them to spontaneously transfer their problem-solving skill to unfamiliar situations. The purpose of this study is to explore the minimum conditions necessary to facilitate the spontaneous transfer of problem solving skill in an unfamiliar context. One hundred and seventy-five subjects were presented with logically identical problems based on the Wason selection task, which differed only in the degree to which a familiar schema could be invoked to help solve the problem. In the pretest stage, only 10.5% of subjects could solve the selection problem in an unfamiliar context, whereas 57.3% could solve it in one that was familiar. The effect of three interventions, prior exposure to a familiar scenario, repeat opportunities on like problems, and process-oriented feedback, on selection task performance in an unfamiliar context was assessed in a posttest stage. Overall, none of the interventions were effective, indicating that the minimum threshold for spontaneous transfer may be above the level of intervention included in this study. Schema theory, implications for instruction, and directions for future research are discussed.     

Young Children''s Disambiguation of Object Name Reference

Children show a disambiguation effect--a tendency to select unfamiliar rather than familiar things as the referents of new names. In previous studies, this effect has been reversed in young 2-year-olds, but not older children, by preexposing the unfamiliar objects, suggesting that attraction to novelty controls 2-years-olds' choices of referents for new names, but a mutual exclusivity and/or lexical gap-filling principle determines preschoolers' selections. Both the disambiguation effect and its reversal by preexposure were replicated in the present study; however, 24-month-olds' rate of selecting unfamiliar over familiar kinds was less when they were simply asked to choose between the items than when they were asked to identify the referents of unfamiliar names. Thus, some young children may have both an attraction to novel tokens and a tendency to honor an abstract lexical principle. Referent selections were also affected by object typicality and word similarity. Correlations between the tendency to acknowledge a new name's unfamiliarity and to treat it like a similar-sounding familiar name suggested that youngsters' phonological matching skills affect their interpretation of new names. Also, 4-year-olds who most often mapped distinctive-sounding new names to unfamiliar kinds tended to admit their unfamiliarity with these names most frequently, suggesting that children's increasing awareness of their own knowledge begins to affect their lexical processing during the preschool years.     

Patterns of Inhibition to the Unfamiliar in Children of Normal and Affectively Ill Mothers

Patterns of 2-3 1/2-year-old children's inhibition and their well and depressed mothers' behaviors in nonsocial and social unfamiliar situations were examined in 88 dyads. Type of unfamiliarity was associated with 2 forms of children's inhibition. 4 more specific patterns were identified: in the nonsocial situation, Inhibition to New Environment with Proximity to Mother; in the social situation, Retreat to Mother, Passivity/Withdrawal from a Stranger, and Wary/Timid Response. The unipolar depressed mothers, particularly those who were recently symptomatic and had a history of the most serious illness, had children who were most inhibited. Serious affective impairment was also associated with the least maternal facilitation of the children's approach to the unfamiliar. Boys were more inhibited to a new environment and girls were more inhibited to a new person. Relations between child inhibition and maternal behaviors suggested that for toddlers and their mothers, encounters with the unfamiliar are interactive events.     

Avoidance of interspecific mating in female Syrian hamsters is stronger toward familiar than toward unfamiliar heterospecific males

Adult Syrian hamster females (Mesocricetus auratus) learn to discriminate against familiar heterospecific males (Turkish hamster, M. brandti). We investigated whether females learn to avoid any heterospecific male after exposure to just one heterospecific male. We predicted that, after being exposed to one heterospecific male, a female would avoid mating not only with that familiar male but also with any unfamiliar heterospecific male. We exposed females to a heterospecific male across a wire-mesh barrier for 8 days and then paired the female with (a) that same heterospecific male or (b) an unfamiliar heterospecific male. Females exhibited lordosis faster and for a longer duration toward the unfamiliar than toward the familiar heterospecific male. However, females were similarly aggressive toward familiar and unfamiliar heterospecific males. Perhaps exposure to stimuli from several heterospecific males (a likely scenario in the wild) would result in females behaving similarly toward familiar and unfamiliar heterospecific males.     

Unconventional Internet genres and their impact on second language undergraduate students' writing process

The Web has become a vast and appealing source of information for undergraduate students writing academic papers. While some online resources are comparable in quality to the materials housed in a library, newly accessible, Web-specific genres, such as interest groups, often undermine traditional expectations of scholarly authority, rigor, and objectivity. Since many of these genres harbor hidden agendas, their impact is often manipulative. Giving the illusion of rigor, they can present challenges for novice undergraduate second language writers who are unfamiliar with North American academic guidelines, yet few studies have examined the impact of such sites on their writing. In order to assess this influence, unconventional, opinion-supporting Web citations in argumentative essays from 70 undergraduate ESL students were isolated and evaluated. Findings revealed that the students who cited unconventional sources appeared to be unaware of their ideological agendas. Additionally, viewing such sources as objective, they used them to support their own viewpoints.     

Neural correlates of face and object recognition in young children with autism spectrum disorder,developmental delay,and typical development

This study utilized electroencephalographic recordings to examine whether young children with autism spectrum disorder (ASD) have impaired face recognition ability. High-density brain event-related potentials (ERPs) were recorded to photos of the child's mother's face versus an unfamiliar female face and photos of a favorite versus an unfamiliar toy from children with ASD, children with typical development, and children with developmental delay, all 3 to 4 years of age (N = 118). Typically developing children showed ERP amplitude differences in two components, P400 and Nc, to a familiar versus an unfamiliar face, and to a familiar versus an unfamiliar object. In contrast, children with ASD failed to show differences in ERPs to a familiar versus an unfamiliar face, but they did show P400 and Nc amplitude differences to a familiar versus an unfamiliar object. Developmentally delayed children showed significant ERP amplitude differences for the positive slow wave for both faces and objects. These data suggest that autism is associated with face recognition impairment that is manifest early in life.     

Maternal, Teacher, and Child Care History Correlates of Children's Relationships with Peers

Mother and teacher correlates of social competence with familiar and unfamiliar peers in 84 children who entered child care at three different times are examined. Social competence at age 4 was assessed with both familiar and unfamiliar peers. Relationships with both initial and 4-year-old teachers were related to social competence with peers. Maternal attachment relationships at 12 months and at 4 years did not predict social competence with peers.     

Recognition of maternal axillary odors by infants

A series of 5 experiments was conducted to determine whether neonates, at approximately 2 weeks of age, can recognize their parents through axillary odors alone. Breast-feeding infants discriminated between their mother's axillary odor and odors produced by either nonparturient or unfamiliar lactating females. In contrast, breast-feeding infants displayed no evidence of recognizing the axillary odors of their father. Likewise, bottle-feeding infants appeared unable to recognize the odor of their mother when presented along with odors from a nonparturient female or an unfamiliar bottle-feeding female. Several hypotheses were presented in an attempt to account for the differential reactions to maternal odors by breast-feeding versus bottle-feeding infants. It was tentatively concluded that, while breast-feeding, infants are exposed to salient maternal odors and thereby rapidly become familiarized with their mother's unique olfactory signature.     

The role of person familiarity in young infants' perception of emotional expressions

This research investigated the role of person familiarity in the ability of 3.5-month-old infants to recognize emotional expressions. Infants (N = 72) were presented simultaneously with two filmed facial expressions, happy and sad, accompanied by a single vocal expression that was concordant with one of the two facial expressions. Infants' looking preferences and facial expressions were coded. Results indicated that when the emotional expressions were portrayed by each infant's own mother, infants looked significantly longer toward the facial expressions that were accompanied by affectively matching vocal expressions. Infants who were presented with emotional expressions of an unfamiliar woman did not. Even when a brief delay was inserted between the presentation of facial and vocal expressions, infants who were presented with emotional expressions of their own mothers looked longer at the facial expression that was sound specified, indicating that some factor other than temporal synchrony guided their looking preferences. When infants viewed the films of their own mothers, they were more interactive and expressed more positive and less negative affect. Moreover, infants produced a greater number of full and bright smiles when the sound-specified emotion was "happy," and particularly when they viewed the happy expressions of their own mothers. The average duration of negative affect was significantly longer for infants who observed the unfamiliar woman than for those who observed their own mothers. These results show that when more contextual information-that is, person familiarity-was available, infants as young as 3.5 months of age recognized happy and sad expressions. These findings suggest that in the early stages of development, infants are sensitive to contextual information that potentially facilitates some of the meaning of others' emotional expressions.     

Lie-telling as a mode of antisocial action: Children’s lies and behavior problems

Despite the fact that lie-telling is a common concern among parents, clinicians, and professionals, there has been little systematic investigation of the lies that children tell in relation to their problematic behaviors, nor of other social factors that may influence this relation. This study explored the relation between children’s problem behaviors and their lie-telling in two studies. The first examined whether children would tell an antisocial lie to an unfamiliar adult to conceal cheating behavior. The second analyzed the relation between children’s problem behaviors, parenting styles, and the frequency of lies reported by parents over two weeks at home. Results suggest that children with higher levels of behavior problems are more likely to tell an antisocial lie to an unfamiliar adult and have a higher frequency of parent-reported lies. Results also indicate that parenting approaches moderate the relation between behavior problems and the frequency of lies that parents report.     

‘They start to get malicia’: teaching tacit and technical knowledge

The sociological study of education involves focusing upon teaching and learning, upon explicit instruction and the acquisition of the tacit knowledge and skills that are essential if learners are to become enculturated into a new habitus. Sociological insight into these processes can come from research on conventional educational settings, but is greater when unfamiliar, settings are studied. This paper focuses upon a pedagogic setting of an unconventional kind – a martial art, capoeira.     

Theory of mind and social interest in zero-acquaintance play situations

Many studies have examined associations between children's theory of mind and social behavior with familiar peers, but to date none have examined how theory of mind might relate to behavior toward unfamiliar peers in a play setting. Forty-four 4-year-olds (21 girls, 23 boys) participated in standard theory-of-mind tasks and in a play session with 3 or 4 other children who were unfamiliar. Children were also tested on general vocabulary ability. No relations were found between theory of mind and social engagement. However, positive associations were found between theory of mind and time spent observing, but not interacting with, other children. Possible explanations of the links between theory of mind, temperament, and social interest are considered.     

Inhibited and uninhibited types of children

An initial group of 100 children who were not selected a priori on any behavioral features were observed in laboratory settings at 14, 20, 32, and 48 months and their behaviors coded for inhibition and lack of inhibition to the unfamiliar. The children who had been extremely inhibited or uninhibited at both 14 and 20 months differed significantly at 4 years of age in behavior and cardiac acceleration to cognitive stress. However, for the entire sample, there was no significant relation between degree of inhibited behavior at 14 or 20 months, on the one hand, and inhibition at 4 years of age, on the other, nor any relation between behavior and heart rate acceleration. These results suggest that the constructs inhibited and uninhibited to the unfamiliar refer to children who fall at the extremes of a phenotypic continuum from shyness and restraint to sociability and affective spontaneity.     

STEM Career Changers’ Transformation into Science Teachers

This study examines the transformation (professional growth) of career-changing women scientists who decided to become teachers. Drawing upon Mezirow’s Transformative Learning Theory, we tracked their transformation for 3 years. Our findings revealed multiple identities, disorientation, a perceived sense of meaninglessness, loss and eventual regain in confidence, gain in pedagogical knowledge and skill, and changed perceptions of the social roles of science teachers and scientists. Driven by personal choice or need (financial, intellectual), such transformations were achieved through active pursuit of meaning in one’s work, critical assessment of assumptions, planning, and trying on the unfamiliar role of a science teacher. It is argued that such transition entails complex changes in thinking about science teaching and identifying oneself as a science teacher.     

Segregation and Immigration: An Examination of School Composition for Children of Immigrants

Immigration in the U.S. continues to increase and to become increasingly diverse. About 20% of U.S. students are children of immigrants. This phenomenon is occurring as schools are racially and ethnically resegregating even as race-based decision making for K-12 schooling has been severely limited. This study examines school segregation for children of immigrants who are often an overlooked component of this phenomenon. Using a large national dataset, the author explores the extent to which children of immigrants are segregated from non-immigrants as well as the extent to which they are segregated from Whites. This study also examines how these relationships vary based on a student's race/ethnicity and socioeconomic status. Results show a society where children of immigrants are segregated in school, which carries with it a host of likely negative outcomes. Implications for policy, practice, and future research are discussed.
