Subject-verb agreement with present and imperfect tenses: A developmental study from 2nd to 7th grade     

Isabelle Negro  Lucile Chanquoy 《European Journal of Psychology of Education - EJPE》2000,15(2):113-133

In French, a verb always agrees in number with its subject. The agreement rule is regularly applied. However, in specific conditions, agreement errors occur. These errors consist in agreeing the verb with the local noun, instead of with the first occurring noun, which is the subject, when two nouns differing in number precede the verb. Currently, one of the most powerful hypotheses to explain this kind of errors suggests that subject-verb agreement errors result from a temporary overload in working memory. In this regard, a developmental study, combined with an analysis of the differences between tenses of the French indicative has been led. We hypothesized a decrease of agreement errors with children’s grades and that the agreement with the imperfect tense may have a lesser cognitive cost than the agreement with the present. The objective of this work was thus to study the management of subject-verb agreement in children from 2nd to 7th grades (between the age of 7 and 12), for the present and the imperfect. The results confirmed that the imperfect is acquired more rapidly than the present. The cognitive cost of the agreement would be lower with the imperfect than with the present. These data were analyzed in the framework of the knowledge development model proposed by Anderson (1983).  相似文献   

Upper limb joint muscle/tendon injury and anthropometric adaptations in French competitive tennis players

The purpose of this study was to examine the relationship between the upper limb anthropometric dimensions and a history of dominant upper limb injury in tennis players. Dominant and non-dominant wrist, forearm, elbow and arm circumferences, along with a history of dominant upper limb injuries, were assessed in 147 male and female players, assigned to four groups based on location of injury: wrist (n = 9), elbow (n = 25), shoulder (n = 14) and healthy players (n = 99). From anthropometric dimensions, bilateral differences in circumferences and in proportions were calculated. The wrist group presented a significant bilateral difference in arm circumference, and asymmetrical bilateral proportions between wrist and forearm, as well as between elbow and arm, compared to the healthy group (6.6 ± 3.1% vs. 4.9 ± 4.0%, P < 0.01; ?3.6 ± 3.0% vs. ?0.9 ± 2.9%, P < 0.05; and ?2.2 ± 2.2% vs. 0.1 ± 3.4%, P < 0.05, respectively). The elbow group displayed asymmetrical bilateral proportions between forearm and arm compared to the healthy group (?0.4 ± 4.3% vs. 1.5 ± 4.0%, P < 0.01). The shoulder group showed significant bilateral difference in elbow circumference, and asymmetrical bilateral proportions between forearm and elbow when compared to the healthy group (5.8 ± 4.7% vs. 3.1 ± 4.8%, P < 0.05 and ?1.7 ± 4.5% vs. 1.4 ± 4.3%, P < 0.01, respectively). These findings suggest that players with a history of injury at the upper limb joint present altered dominant upper limb proportions in comparison with the non-dominant side, and such asymmetrical proportions would appear to be specific to the location of injury. Further studies are needed to confirm the link between location of tennis injury and asymmetry in upper limb proportions using high-tech measurements in symptomatic tennis players.  相似文献   

Alternate Conceptions of Preservice Elementary Teachers: The Itakura Method     

Aaron D. Isabelle  Cornelis de Groot 《Journal of Science Teacher Education》2008,19(5):417-435

In this study, we determined the effectiveness of the inquiry-based Itakura method for mediating alternate conceptions of preservice elementary teachers (N = 38) in an integrated mathematics, science, and technology methods course. We investigated alternate conceptions in the expansion of solids due to heating. There was a significant increase in participants’ immediate learning gains after participating in the Itakura method. Retention data was gathered after 1, 2, and 3 months. After 3 months, retention levels dropped slightly, but not significantly. Responses revealed that the majority of the participants did not revert back to alternate conceptions after 3 months.  相似文献   

High-Ability Grouping: Benefits for Gifted Students’ Achievement Development Without Costs in Academic Self-Concept     

Franzis Preckel  Isabelle Schmidt  Eva Stumpf  Monika Motschenbacher  Katharina Vogl  Vsevolod Scherrer  Wolfgang Schneider 《Child development》2019,90(4):1185-1201

Effects of full-time ability grouping on students’ academic self-concept (ASC) and mathematics achievement were investigated in the first 3 years of secondary school (four waves of measurement; students’ average age at first wave: 10.5 years). Students were primarily from middle and upper class families living in southern Germany. The study sample comprised 148 (60% male) students from 14 gifted classes and 148 (57% male) students from 25 regular classes (matched by propensity score matching). Data analyses involved multilevel and latent growth curve analyses. Findings revealed no evidence for contrast effects of class-average achievement or assimilation effects of class type on students’ ASC. ASC remained stable over time. Students in gifted classes showed higher achievement gains than students in regular classes.  相似文献   

Development of Gender Typicality and Felt Pressure in European French and North African French Adolescents     

Adam J. Hoffman  Florence Dumas  Florence Loose  Annique Smeding  Beth Kurtz-Costes  Isabelle Régner 《Child development》2019,90(3):e306-e321

Trajectories of gender identity were examined from Grade 6 (M_age = 11.9 years) to Grade 9 in European French (n = 570) and North African French (n = 534) adolescents, and gender and ethnic group differences were assessed in these trajectories. In Grade 6, boys of both ethnic groups reported higher levels of gender typicality and felt pressure for gender conformity than girls. European French girls and boys and North African French girls reported decreasing gender typicality from Grade 6 to Grade 9, whereas North African French boys did not change. Felt pressure decreased among girls, did not change in European French boys, and increased in North African French boys. Ethnic and gender differences in gender identity development are discussed.  相似文献   

Positive biases in self-assessment of mathematics competence, achievement goals, and mathematics performance     

Caroline Dupeyrat  Christian EscribeNathalie Huet  Isabelle Régner 《International Journal of Educational Research》2011,50(4):241-250

The study examined how biases in self-evaluations of math competence relate to achievement goals and progress in math achievement. It was expected that performance goals would be related to overestimation and mastery goals to accurate self-assessments. A sample of French high-school students completed a questionnaire measuring their math achievement goals and their perceived competence in math. Students’ math grades for the three trimesters of the school year were collected from school records. Bias in self-evaluations was computed by comparing students’ rating on the ‘perceived competence in math’ scale with their actual math achievement as measured by their second trimester math grades. Students were classified into one of three groups (over-raters, accurate raters, or under-raters) depending on whether their self-perceptions of competence in math were higher than, similar to, or lower than their relative math achievement in their class. As expected, overrating of one's performance was related to performance goals. Furthermore, the over-raters were the only group who progressed in their math achievement from Trimester 2 to 3. No relation was found between mastery goals and accurate self-assessment.  相似文献
