The development of the ability to recognize the meaning of iconic signs

Early developmental psychologists viewed iconic representation as cognitively less complex than other forms of symbolic thought. It is therefore surprising that iconic signs are not acquired more easily than arbitrary signs by young language learners. One explanation is that children younger than 3 years have difficulty interpreting iconicity. The current study assessed hearing children's ability to interpret the meaning of iconic signs. Sixty-six 2.5- to 5-year-olds who had no previous exposure to signs were required to match iconic signs to pictures of referents. Whereas few of the 2.5-year-olds recognized the meaning of the iconic signs consistently, more than half of the 3.0-year-olds and most of 3.5-year-olds performed above chance. Thus, the ability to recognize the meaning of iconic signs gradually develops during the preschool years. Implications of these findings for sign language development, receptive signed vocabulary tests, and the development of the ability to interpret iconic symbols are discussed.     

WHAT IS AV DOING IN A HUMANITIES DEGREE?

The Communication module of the B.A. (Hons) Humanities modular degree at Bristol Polytechnic involves non‐Art & Design students in practical audio‐visual media work through ‘live’ projects undertaken for ‘clients’ in the community ‐‐ schoolteachers, social workers, charities, etc. ‐‐ the work being carried out in teams of between 2 and 5.

The theoretical base of the course is face‐to‐face interaction in real‐life situations such as the classroom and the television interview. The method of assessment here is to present examinees with selected communicative events on videotape and call for analysis and comparison, and evaluation of the theoretical approaches employed. This places a premium on students being able to apply theory directly to real‐life situations, rather than rehearse those theories in essay form.

The course is both intended by the staff and perceived by the students to be distinctly different from the other modules of an otherwise book‐based degree in providing for the essentially practical application of ideas and a basic introduction to alternative modes of communication. By means of the projects, drawn from a variety of sources far removed from the degree course and the institution, the analytical, research, and design skills of the students are applied in a realistic way to broaden their own perspectives and to be of lasting benefit within the community.     

An Attempt To Measure and Facilitate Counselor Effectiveness

This study evaluated the use of Interpersonal Process Recall (IPR) with videotape (as opposed to more traditional methods) in improving the effectiveness of practicum students. The practicum students were randomly assigned to one of three treatment groups: (a) a video-IPR, (b) an audio-IPR, and (c) supervision using an audiotape of a regular counseling session. Three judges were asked to rate videotapes of 54 practicum students conducting their final counseling session with a coached client. The judges rated two time-samplings of the final session by means of a scale consisting of three parts: (a) 33 behavioral and feeling items, (b) a single global evaluation representing the normal curve with the baseline divided into eight equal segments, and (c) a request for the judges to write any adjectives or phases that they felt described the practicum student. The results were not as convincing as had been anticipated. This article discusses possible reasons that the results were not convincing and implications the results have for future research within this area of counselor education.     

Designing Curriculum-Based Mathematics Professional Development for Kindergarten Teachers

This study examines the influence of a year-long mathematics professional development program on Kindergarten teachers’ beliefs, content knowledge, instructional practices, and their students’ achievement. The professional development program is grounded in the theoretical construct of learner-centered professional development and focuses on supporting teachers’ integration of standards-based pedagogies aligned with the Common Core State Standards in Mathematics. Data analysis included examining 15 Kindergarten teachers’ mathematics content knowledge, their beliefs about mathematics, their enactment of student-centered pedagogies, and student achievement on curriculum-based assessments. Findings indicated that teachers adopted more student-centered pedagogies and embraced more student-centered beliefs about mathematics teaching during their time in the project. Further, Kindergarten teachers also demonstrated gains in their mathematical content knowledge, and those content knowledge gains were linked to gains in student achievement.     

The Roles of Parental Support and Family Stress in Adolescent Sleep

The current study examines the association between parental support and adolescent sleep under varying levels of family stress. Participants included 316 adolescents (M_age = 16.40 years, 43% male) and their parents (M_age = 45.67 years, 91% mothers) from diverse ethnic backgrounds. Both adolescents and parents completed questionnaires and adolescents wore wrist actigraphs and completed self‐reports on their sleep for 7 consecutive days. Results indicated that under contexts of family stress, more parental support was linked to longer sleep duration, less sleep variability, and less time spent awake during the night. Findings suggest that under contexts of family stress, cohesive family relationships may provide a sense of stability and security that is necessary for healthful sleep.     

Latent Profiles of Reading and Language and Their Association With Standardized Reading Outcomes in Kindergarten Through Tenth Grade

The objective of this study was to determine the latent profiles of reading and language skills that characterized 7,752 students in kindergarten through tenth grade and to relate the profiles to norm-referenced reading outcomes. Reading and language skills were assessed with a computer-adaptive assessment administered in the middle of the year and reading outcome measures were administered at the end of the year. Three measures of reading comprehension were administered in third through tenth grades to create a latent variable. Latent profile analysis (LPA) was conducted on the reading and language measures and related to reading outcomes in multiple regression analyses. Within-grade multiple regressions were subjected to a linear step-up correction to guard against false-discovery rate. LPA results revealed five to six profiles in the elementary grades and three in the secondary grades that were strongly related to standardized reading outcomes, with average absolute between-profile effect sizes ranging from 1.10 to 2.53. The profiles in the secondary grades followed a high, medium, and low pattern. Profiles in the elementary grades revealed more heterogeneity, suggestive of strategies for differentiating instruction.     

Empirical versus subjective procedures for identifying gender differences in science test items

When judgmental and statistical procedures are both used to identify potentially gender-biased items in a test, to what extent do the results agree? In this study, both procedures were used to evaluate the items in a statewide, 78-item, multiple-choice test of science knowledge. Only one item was flagged by the sensitivity reviewers as being potentially biased, but this item was not flagged by the statistical procedure. None of the nine items flagged by the Mantel-Haenszel procedure were flagged by the sensitivity reviewers. Eight of the nine statistically flagged items were differentially easier for males. Four of these eight measured the same category of objectives. The authors conclude that both judgmental and statistical procedures provide useful information and that both should be used in test construction. They caution readers that content-validity issues need to be addressed when making decisions based on the results of either procedure.     

Screening for problem parenting: preliminary evidence on a promising instrument

This paper reports on efforts aimed toward the development of more effective procedures for identifying mothers who are at elevated risk for problems in parenting. We present data from two independent samples of known maladaptors and corresponding comparison mothers and report on our attempts to cross-validate a promising screening instrument composed of items that index social support and parenting attitudes. The resultant 20-item scale correctly identified over 90% of maladaptive and comparison mothers. When this scale was cross-validated on a second independent sample of maladaptors and comparison mothers, it was again almost 90% accurate. Issues concerning the field application of this promising instrument are discussed and its possible limitations are considered.
