A developmental analysis of the relationship between response strength and punishment

Two levels of training (100 vs. 500 trials) and two ages of rats (young and adult) were used in a developmental analysis of the relationship between response strength and the effects of punishment. The apparatus was a Y maze with three discriminably different arms. After 100 or 500 reinforced trials, subjects were shocked each time they responded in one arm. The recovery sessions followed the punishment session. Results from the punishment day indicated that: (a) young rats received a greater amount of shock, and (b) additional training increased the amount of shock received by the young but decreased it in the adults. The recovery data showed that: (a) the suppressive effects of punishment were greater for the adults than for the young, and (b) the recovery scores were not influenced by degree of overtraining. The Age by Overtraining interaction suggested that the relationship between response strength and punishment is age dependent. The age differences found with the amount-of-shock and recovery measures provided additional support for the position that younger rats are less competent than adult rats in inhibiting responses.

     

Does teachers’ pedagogical content knowledge affect their fluency instruction?

The relation is studied between teachers’ pedagogical content knowledge of reading and the quality of their subsequent classroom behaviour in teaching fluent reading. A confirmatory factor analysis model with two latent variables is tested and shows adequate goodness-of-fit indices. Contrary to our expectations, the results of structural equation modelling reveal a small but significant γ-value of .29, indicating that only 8% of the variance in teachers’ classroom behaviour in teaching fluent reading is accounted for by teachers’ pedagogical content knowledge of reading. Presumably teacher knowledge is not as stable and conclusive as one might think. More research is needed in determining the factors that work restricting for teachers in putting their knowledge into classroom practice. It is recommended that preservice and in-service teacher training should not be limited to transfer of knowledge, but should also assist teachers in designing and performing effective fluent reading instruction.     

Personality structure,instructional outcomes,and instructional preferences

Four instructional treatments differing in structure and student responsibility were used with 60 abstractthinking and 60 concrete-thinking students. As predicted, abstract students preferred those treatments with less structure and more responsibility; however, abstract and concrete students showed similar achievement levels as a result, of each treatment. The differentiated outcomes hypothesis is offered to account for the findings.

Résumé Quatre méthodes de traitement pédagogique de structure et de responsabilité des étudiants ont été employées avec 60 étudiants pensant abstraitement et 60 étudiants pensant de manière concrète. Ainsi que prévu, les étudiants pensant abstraitement préféraient les méthodes ayant moins de structure et plus de responsabilité. Les deux catégories d'étudiants ont toutefois obtenu des niveaux d'accomplissement pareils avec chaque méthode de traitement. L'hypothèse des aboutissements différenciés est offerte comme explication des conclusions.

Occupational and educational aspirations and attainment of young adults with and without LD 2 years after high school completion

A national longitudinal database was used to compare the aspirations and attainment of individuals with and without learning disabilities (LD) 2 years after high school completion. Analyses revealed that individuals with LD reported lower graduation rates, were more likely to aspire to moderate- (men) or low-prestige (women) occupations, and were more likely to be employed and less likely to be enrolled in some type of postsecondary education program than their nondisabled peers. High educational aspirations in Grade 12 and successful completion of an academic or college-prep high school program were equally important in predicting 2-year postsecondary status for adolescents enrolled in postsecondary education regardless of disability status. However, depending on disability status, different predictors were identified for individuals who were either employed or out of the workforce. These results point to a continued need for transition planning and support for young adults with LD and suggest ways in which professionals can anticipate and adjust for identified differences in aspirations and postsecondary attainment.     

Teacher self-efficacy moderates the relations between imposed pressure from imposed curriculum changes and teacher stress

Based on the Job Demands-resources (RD-R) model, the aim of the current study was to examine how pressure arising from imposed curriculum changes and teacher self-efficacy relate to perceived stress in teachers. Participants (839 teachers working in English schools) completed an online survey that contained questions about demographics, self-reported pressure from imposed curriculum changes, teacher self-efficacy, and perceived stress. Pressure from imposed curriculum changes was positively, and teacher self-efficacy negatively, related to perceived stress. Teacher-self efficacy moderated relations between pressure from imposed curriculum changes and perceived stress. High teacher self-efficacy was associated with lower perceived stress, relative to low teacher self-efficacy, when pressure from imposed curriculum changes was low. The differential advantage offered by high self-efficacy declined as pressure from imposed curriculum changes increased.     

The adaptation of hearing parents of hearing-impaired youths

This study evaluated the emotional and marital adjustment of hearing parents of hearing-impaired youths. Participants included mothers and fathers of hearing-impaired youths and mothers and fathers of hearing youths. In contrast with expectations based on clinical impressions reported in the literature, parents of hearing-impaired youths reported less symptomatology than did parents of hearing youths, and there were no differences in the marital satisfaction of parents in intact families. Moreover, parental adjustment was not associated with the duration of time since the child was diagnosed as hearing impaired. In addition, hierarchical multiple regression analyses revealed that family cohesion was associated with low maternal symptomatology and high marital satisfaction for both spouses. For mothers, low symptomatology was associated with low stress and female gender of child; high marital satisfaction also was linked with a less severe degree of hearing loss in the youth.     

Assessment of Communication Competencies in Engineering Design Projects

Reforms in engineering education have caused a shift from the traditional stand-alone course in technical communication for Engineering students towards communication training integrated in courses and design projects that allows students to develop four layers of competence. This shift creates opportunities for realistic and situated learning, but offers challenges for assessment of communication competence at student, course and program levels. On the basis of a detailed definition of communicative competence, three formats for integrated communication training are described: Linked to design projects, integrated in design projects and integrated at program level. Assessment of communication competence in these formats is constrained by their characteristics with regard to student motivation, individual and group work, and situated learning.
