Abstract:
Accountability systems that measure student learning rather than student achievement have the potential to more accurately evaluate school quality. However, one methodological concern has remained surprisingly absent from discussions of value-added modeling. Standardized assessments that exhibit either positive or negative correlations between achievement and achievement gains will produce value-added estimates that contradict actual patterns of school effectiveness. This study uses student-level state assessment data to explore the ramifications of these relationships for value-added indicators. Within this state's assessment, the author finds strong negative relationships between achievement and subsequent achievement gains--initially low-scoring students appeared to gain more than their high-achieving peers. Because students are not randomly assigned to schools by achievement, these child-level correlations strongly influence school-level value-added estimates, in some cases quite dramatically. However, the manifestation of these relationships varies across four different analytic techniques, depending on how a particular approach modeled the associations between initial status and gain.

Abstract:
This paper reports classroom research dealing with the difficulties encountered by schoolchildren in the acquisition of angle concept. Two obstacles were pointed out in previous studies: the side-length obstacle and the salience of the prototypical right angle. The first aim of the present study is to determine the extent to which a teaching sequence based on a concrete situation in the meso-space can enable pupils to progress in their conceptualization of angles. This problem situation is based on the notion of visual field. The angle appears in real space between two infinite directions that correspond to two lines of sight. The specificity of this situation is to confront pupils with an angle between two infinite directions in space. The second goal of this research is to study the links between the two obstacles. To answer these research questions, we compared two versions of the teaching sequence, one dynamic (the angle varies) and one static (the angle does not vary) in 3rd and 4th grade classes. The unfolding of the sequence was analyzed and pupils were tested individually before and after the sequence. They were requested to draw angles and angle variations. The results showed that (1) the sequence helped the pupils progress (2) the obstacle of side-length is not the only difficulty faced by pupils; the salience of the prototypical right angle constitutes a real learning obstacle and (3) the type of angle produced and the ability to change its size are linked. In conclusion, the implications for teaching are presented. (Contains 7 tables and 8 figures.)

Abstract:
In contrast to the well documented male advantage in psychometric mental rotation tests, gender differences in chronometric experimental designs are still under dispute. Therefore, a systematic investigation of gender differences in mental rotation performance in primary-school children is presented in this paper. A chronometric mental rotation task was used to test 449 second and fourth graders. The children were tested in three separate groups each with different stimulus material (animal drawings, letters, or cube figures). The results show that chronometric mental rotation tasks with cube figures--even rotated in picture plane only--were too difficult for children in both age groups. Further analyses with animal drawings and letters as stimuli revealed an overall gender difference in response time (RT) favoring males, an increasing RT with increasing angular disparity for all children, and faster RTs for fourth graders compared to second graders. This is the first study which has shown consistent gender differences in chronometric mental rotation with primary school aged children regarding reaction time and accuracy while considering appropriate stimuli.

Abstract:
This article relates about some results of an interdisciplinary research project analyzing influencing factors of children's spatial orientation competence in real space carried out by geography educators and psychologists. The focus is on the concept of representation as a theoretical foundation. The research design for collecting data of independent and dependent variables (map-based orientation competence, MBO), and the self-developed measuring instrument are explained. Altogether, 328 pupils of third, fourth, and fifth grade (aged 8-12 years) were tested. The orientation competence of children in strange spaces was slightly above the average, and grew with age. The most spectacular increase was detected on the transition from third to fourth grade. Additionally, boys scored higher than girls. The results also showed that along with age and gender, spatial intelligence (mental rotation) and previous knowledge shape MBO. A limited influence can be attributed to self-concept and previous experiences, while interest has no influence on MBO at all. (Contains 6 tables and 3 figures.)

Abstract:
Educational effectiveness research often appeals to "value-added models (VAM)" to gauge the impact of schooling on student learning net of the effect of student background variables. A huge amount of cross-sectional studies do not, however, meet VAM's requirement for longitudinal data. "Contextualised attainment models (CAM)" measure the influence of schools on student outcomes controlling for family background characteristics in cross-sectional studies. It is argued that the latter are adequate substitutes for student prior attainment. Drawing on data from a 3-point longitudinal study in the city of Berlin, Germany (n = 3,074), reading and mathematics achievement of primary students are investigated to assess effectiveness measures of schools. Estimates are compared for a 3-level growth curve analysis (VAM), a hierarchical linear model controlling for background characteristics (CAM), and one additionally controlling for prior achievement scores (prior attainment model). The article contributes to the enhancement of a feedback culture for cross-sectional study results. (Contains 5 tables, 5 figures and 6 notes.)
