Testgütekriterien der „Profilanalyse nach Grießhaber“. Evaluation eines Verfahrens zur Erfassung grammatischer Fähigkeiten von ein- und mehrsprachigen Grundschulkindern

A diagnostic goal of the “Profile analysis according to Grießhaber” is the assessment of the grammatical ability to place verbs in German sentences in the correct syntactical position. To evaluate the test quality for the first time, 403 monolingual and multilingual primary school children were randomly assigned to three different test materials: Test material that specifically stimulated the target competence led to the best test results. This indicates a low objectivity of application. In addition, ceiling effects for primary school children were detected, which means that the profile analysis can only slightly differentiate among the grammatical abilities of the children. Retest reliability and objectivity of analysis are also too small. In summary, the test quality of the assessment tool should be improved with respect to all of the test quality criteria considered. Hence, we recommend standardizing the profile analysis better and adding more sensitive diagnostic criteria for primary school aged children. Other aspects of profile analysis, for example the improvement of diagnostic competencies of teachers, are recommended for future research.     

Comment on Elbers' article: Which competence? For whom? For what?

In reaction to Elbers' paper, several comments are made concerning the unit of analysis used to observe children's cognitive activity, the nature of the competence assessed, and the role of the task, or the object of knowledge, in which the child and the adult interact. It is argued that the testing situation is a social event in which the adult and the child interact on a specific object and negotiate a common interpretation of the task and the situation. From this perspective, the testing situation appears to be a learning situation in which new knowledge is acquired.     

Le Logiciel ‘Derive’ comme revelateur de phenomenes didactiques lies a l'utilisation d'environnements informatiques pour l'apprentissage

In this article, we address the issue of integration of computer environments in the mathematics secondary curriculum, by referring to the results of a research project carried out with the software DERIVE. Firstly, we present the research project and its theoretical framework, secondly, we evidence some didactical phenomenas linked to the DERIVE transposition of mathematical knowledge and learning processes in this environment which, in our opinion, play a crucial role in integration issues.This revised version was published online in September 2005 with corrections to the Cover Date.     

The Heuristic for Thinking About Culturally Responsive Teaching (HiTCRiT)

Michèle was hurrying to class. How, she thought, could she offer the students in her African American English in Society and Schools class a method of understanding, comparing, and abstracting the studies they had been reading in class? The heuristic described in this study evolved from a desire to capture aspects of several seminal studies that illustrated how African American English was deployed in classrooms for productive work with African American students. Michèle recalled that whenever she asked graduate students or practicing teachers what they, other teachers, and schools might do to improve the schooling of students of color, one of the most consistent responses was Culturally Responsive Pedagogy (CRP). However, when pressed and asked what one would detect in classrooms where CRP is being put into practice, few were able to specify what an observer might see. Specifying the dimensions of CRP and its relationship to the heuristic had not been on Michèle’s mind. Even so, it was during the class discussion that the heuristic’s relevance to CRP became clearer. Jonathan, who had been tapped as a teaching assistant in an English language arts methods class, believed HiTCRiT could be modified to use with teacher education candidates, as a substitute for the standardized lesson planning tool used in the department. He piloted its use with the class the following semester. Utilizing HiTCRiT to explain research and existing practices as well as to assist teachers in creating culturally relevant instruction modified and shaped it, creating a more robust tool. Thus, the HiTCRiT came into being and came to inform our thinking and teaching practice.     

Assessment of the effects of student response systems on student learning and attitudes over a broad range of biology courses

With the advent of wireless technology, new tools are available that are intended to enhance students' learning and attitudes. To assess the effectiveness of wireless student response systems in the biology curriculum at New Mexico State University, a combined study of student attitudes and performance was undertaken. A survey of students in six biology courses showed that strong majorities of students had favorable overall impressions of the use of student response systems and also thought that the technology improved their interest in the course, attendance, and understanding of course content. Students in lower-division courses had more strongly positive overall impressions than did students in upper-division courses. To assess the effects of the response systems on student learning, the number of in-class questions was varied within each course throughout the semester. Students' performance was compared on exam questions derived from lectures with low, medium, or high numbers of in-class questions. Increased use of the response systems in lecture had a positive influence on students' performance on exam questions across all six biology courses. Students not only have favorable opinions about the use of student response systems, increased use of these systems increases student learning.     

Student‐centered integrated anatomy resource sessions at Alfaisal University

Alfaisal University is a new medical school in Riyadh, Kingdom of Saudi Arabia that matriculates eligible students directly from high school and requires them to participate in a hybrid problem‐based learning (PBL) curriculum. PBL is a well‐established student‐centered approach, and the authors have sought to examine if a student‐centered, integrated approach to learn human structures leads to positive perceptions of learning outcomes. Ten students were divided into four groups to rotate through wet and dry laboratory stations (integrated resource sessions, IRSs) that engaged them in imaging techniques, embryology, histology, gross anatomy (dissections and prosections), surface anatomy, and self‐directed learning questions. All IRSs were primarily directed by students. During two second‐semester organ system blocks, forty students responded to a structured questionnaire designed to poll students' perceptions of changes in their knowledge, skills, and attitudes as a result of IRS. The majority (60%) of students felt that the student‐centered approach to learning enhanced their medical knowledge. Most students also felt that the IRS approach was advantageous for formulating clear learning objectives (55%) and in preparing for examinations (65%). Despite their positive feelings toward IRS, students did not view this learning approach as an adequate replacement for the knowledge gained from lectures and textbooks. Students' performance on objective structured practical examinations improved significantly for the two curricular blocks that included IRS compared with earlier non‐IRS blocks. A student‐centered approach to teach human structure in a hybrid PBL curriculum may enhance understanding of the basic sciences in first‐year medical students.

Challenges in identifying target skills for math disability screening and intervention

Gersten, Jordan, and Flojo (in this series) review their research on math difficulties, with an emphasis on applying current knowledge to inform practices of early identification and intervention. On a practical level, educators are in dire need of empirically based screening and intervention tools. From a scientific perspective, it is important to recognize the need to clearly define what we seek to identify and remediate, and to acknowledge that we are currently far from achieving this goal despite recent advances in the field. Among the studies reviewed by Gersten et al., as well as other studies by several other researchers, there is much variability in how mathematics difficulties are defined and measured, and even in the terms used to refer to them. I address the degree of consensus and controversy currently characterizing the state of math learning disabilities research, with an emphasis on the usefulness of a developmental perspective in appraising this young field.     

Effects of math anxiety and perfectionism on timed versus untimed math testing in mathematically gifted sixth graders

This study was designed to examine the effects of math anxiety and perfectionism on math performance, under timed testing conditions, among mathematically gifted sixth graders. We found that participants had worse math performance during timed versus untimed testing, but this difference was statistically significant only when the timed condition preceded the untimed condition. We also found that children with higher levels of either math anxiety or perfectionism had a smaller performance discrepancy during timed versus untimed testing, relative to children with lower levels of math anxiety or perfectionism. There were no statistically significant gender differences in overall test performance, nor in levels of math anxiety or perfectionism; however, the difference between performance on timed and untimed math testing was statistically significant for girls, but not for boys. Implications for educators are discussed.     

Development,Implementation, and Assessment of a Lecture Course on Cancer for Undergraduates

The war on cancer has been waged for nearly 40 years, yet the cancer burden remains high, especially among minority and underserved populations. One strategy to make strides in the war on cancer and its disparate impacts is to increase the diversity of the cancer research workforce. We describe an approach to recruit a diverse population of future cancer researchers from an undergraduate student population at a minority-serving land-grant institution. Specifically, we have addressed the following questions: Given the dearth of published reports of undergraduate cancer courses, is it possible for undergraduates at a land-grant institution (rather than a research or medical institution) to successfully learn cancer biology from a lecture-based course? Can we develop a template that has the potential to be used by others to develop and implement an undergraduate cancer course? Can such a course stimulate interest in careers in cancer research? Based on a learning gains analysis, students were able to learn cancer content and related skills, and based on student surveys, students'' interest in cancer research was stimulated by course participation. We have identified aspects of our course development process that were critical for the successful development, implementation, and assessment of the course.
