Using a Table of Specifications to improve teacher-constructed traditional tests: an experimental design

We investigated if instruction on a Table of Specifications (TOS) would influence the quality of classroom test construction. Results should prove informative for educational researchers, teacher educators, and practising teachers interested in evidenced-based strategies that may improve assessment-related practices. Fifty-three college undergraduates were randomly assigned to an experimental (exposed to the TOS strategy) and a comparison condition (no specific strategy support) and given materials for an instructional unit to use to construct a classroom test. Results of a multivariate analysis of covariance suggested that students exposed to the TOS strategy constructed a test with higher test content evidence but not response process evidence scores. Furthermore, we found that treatment participants were able to accurately complete the TOS tool and choose items that reflected the subject matter specified in the TOS tool. However, they experienced difficulty selecting items at the cognitive level specified in the TOS tool.     

Infants' Perception of Emotion From Body Movements

Adults recognize emotions conveyed by bodies with comparable accuracy to facial emotions. However, no prior study has explored infants' perception of body emotions. In Experiment 1, 6.5‐month‐olds (n = 32) preferred happy over neutral actions of actors with covered faces in upright but not inverted silent videos. In Experiment 2, infants (n = 32) matched happy and angry videos to corresponding vocalizations when the videos were upright but not when they were inverted. Experiment 3 (n = 16) demonstrated that infants' performance in Experiment 2 was not driven by information from the covered face and head. Thus, young infants are sensitive to emotions conveyed by bodies and match them to affective vocalizations, indicating sophisticated emotion processing capabilities early in life.     

Concreteness Fading in Mathematics and Science Instruction: a Systematic Review

A longstanding debate concerns the use of concrete versus abstract instructional materials, particularly in domains such as mathematics and science. Although decades of research have focused on the advantages and disadvantages of concrete and abstract materials considered independently, we argue for an approach that moves beyond this dichotomy and combines their advantages. Specifically, we recommend beginning with concrete materials and then explicitly and gradually fading to the more abstract. Theoretical benefits of this “concreteness fading” technique for mathematics and science instruction include (1) helping learners interpret ambiguous or opaque abstract symbols in terms of well-understood concrete objects, (2) providing embodied perceptual and physical experiences that can ground abstract thinking, (3) enabling learners to build up a store of memorable images that can be used when abstract symbols lose meaning, and (4) guiding learners to strip away extraneous concrete properties and distill the generic, generalizable properties. In these ways, concreteness fading provides advantages that go beyond the sum of the benefits of concrete and abstract materials.     

A Model of Academic Self-Concept for High School Hispanic Students in New York

This study examined how Hispanic students’ academic self-concept influences the independent variables of family academic expectations, peer relationships, schoolwork, and student–teacher relationships. A survey was administered to 222 ninth-grade students in Long Island, New York, 99 of whom self-identified as Hispanic. A structural equation model analyzed the influence of the independent variables on the dependent variable, academic self-concept. A multiple regression analysis indicated that peer relationships, family academic expectations, and schoolwork were significant predictors of students’ academic self-concept. Peer relationships was a modifying variable on students’ academic self-concept.     

Tipping the Balance from Expert to Facilitator: Examining Myths about Being a Teacher Educator

This self-study addresses two questions: (1) how did self-study aid the teacher educator in interrogating her beliefs about and mediate her projection of teacher-as-facilitator versus teacher-as-expert? and (2) in what ways did prospective elementary teachers in an undergraduate, interdisciplinary science course exert control over their learning as a result of the teacher educator's self-interrogation of practices? In her teaching role with prospective teachers, Nicole explored a major myth about teaching concerning the image of the professor as the primary expert in the classroom. Critical events analysis revealed instances where she exerted power as an expert or assumed the role of facilitator. Instead of clearly marked instances where she took actions to exert her various roles in the classroom, she found that classroom events could not be categorized neatly. There were cases where she acted as an expert and students felt free to make their own decisions about their learning. When she was uncertain or attempted to relinquish control, students often responded by not taking control of their learning.     

The Relationship Between “Teen Mom” Reality Programming and Teenagers' Beliefs About Teen Parenthood

A survey was conducted with U.S. high school students (M = 16.57 years of age) from the Midwest to examine whether exposure to “teen mom” reality programming (e.g., 16 and Pregnant, Teen Mom) was related to teens' perceptions of teen parenthood. Contrary to our hypotheses, analyses revealed that exposure to teen mom reality programming was related to an increased tendency to believe that teen mothers have an enviable quality of life, a high income, and involved fathers. Teens who perceived reality television as realistic were most likely to hold these perceptions. The findings are discussed in terms of cultivation theory.     

How do technique and coordination change during learning of a whole-body task: Application to the upstart in gymnastics

ABSTRACT

When learning swinging skills on a bar there has been conflicting advice in the research literature regarding whether to coach the “gold standard” technique to novices. The present study aimed to determine how technique (joint angle time histories) and (inter-limb) coordination changed as novice gymnasts learned a fundamental gymnastics skill (the upstart). It was hypothesised that both technique and coordination would become more like an expert as learning progressed. Eight novice gymnasts, unable to perform an upstart, underwent four months of training, with the number of successful upstarts out of 10 recorded at the start and then every month subsequently. In the first and last sessions motion capture was used to determine joint kinematics. Root mean squared differences for the joint angle time histories and continuous relative phase at the shoulder and hip were calculated between the novices and an expert gymnast. As training progressed technique and coordination became more like the expert gymnast. The more successful novices were better able to time their actions within the swing than the less successful novices. Gymnastics coaches teach towards a “gold standard” technique since being successful at the skill is not the only goal, as considerations for future skill development are made.     

Parent–child conversations about letters and pictures

Learning about letters, and how they differ from pictures, is one important aspect of a young child??s print awareness. To test the hypothesis that parent speech provides children with information about these differences, we studied parent?Cchild conversations in CHILDES (MacWhinney, 2000). We found that parents talk to their young children about letters, differentiating them from pictures, by 1?C2?years of age and that some of these conversational patterns change across the preschool years in ways that emphasize important features of letters, such as their shape. We also found that children talk about letters and pictures in distinct ways, suggesting an implicit understanding of some of the differences between letters and pictures at an early age. Some differences in parent?Cchild conversations about letters were found as a function of socioeconomic status: Lower SES families appeared to focus more on alphabetic order than higher SES families. The general letter knowledge expressed in these conversations suggests that everyday interactions are an important component of the home literacy environment and that they differ, in some respects, as a function of child age and family background.     

“Moving” the Pyramids of Giza: Measuring the Effects of Ethics Education in a Visual Communication Curriculum

As mass communication scholars and educators, we should be greatly concerned about how we teach ethics to our students. This research posits improving the quality of mass communication education with the intention of producing top-notch journalists who are dedicated to raising the credibility of the profession. Specifically, the research assesses the effects of integrating ethical content within a visual communication course, focusing on two critical and timely issues in visual journalism: the acceptability of graphic photographs and image manipulation. Findings showed significant differences in how participants viewed selected ethical issues in visual journalism from time 1 to time 2.
