Discourses about a teacher's self-initiated change in praxis: Storylines of care and support

At the foreground of this article is an account of an experienced science teacher's self-initiated change in praxis within an inquiry community. From classroom observation and interviews, data interpretations are made about the discursive practices of the teacher and his colleagues. In particular, the teacher's change in praxis is attributed to his dissatisfaction with previous practice, realization that alternatives were likely to provide better outcomes for his students, commitment to improving his practice, and a supportive school community in which teachers felt comfortable taking personal risks and engaging in professional discussions. The collaborative culture of the study site was characterized by the teachers' caring ethic for their students.     

Senior Design Project Course: A Case Study

The two‐quarter Senior Design Project course given in the Computer Science and Engineering Department of Auburn University gives undergraduate students a significant computer system development experience by working on a project from proposal to prototype. Heavy emphasis is placed on team‐ and project‐management principles, team presentations, the application of standard structured development methodologies, and the generation of formal deliverables after each project phase. Project ideas are canvassed from faculty, graduate students, local industry and community, and from the students themselves. We believe that the knowledge and experience acquired by students from working in a team on a substantial project gives them an insight and perspective that is unattainable through the standard lecture paradigm. The course has received enthusiastic endorsement from industry, accrediting boards, and participating students (albeit at the end of the course!).     

Predictors of teachers perceived self-competence in classroom management

The purpose of this exploratory study was to identify predictors of teacher manageability beliefs (the degree to which teachers believe they can personally manage a behavior). One hundred and eighty-two teachers completed the 39-item, nine-subtest Teacher Manageability Scale (TMS), which asked participants to rate each behavior (on a 5-point scale) by responding to the question “How easily can you manage the behavior when any student…?” Results of a multivariate regression analysis evaluating the relationship between the nine subtests (dependent variables) and eleven teacher-reported independent variables indicated that between 13% and 18% of the variance was predicted for the six TMS subtests achieving significance. The variables related to the greatest number of dependent measures were student academic achievement and socioeconomic status. Surprisingly, principal's disciplinary support and class size (enrollment) failed to predict even a single subtest. Implications for professional educators working with students identified for special educational services and future research are discussed.     

Observations and ratings of preschool children's social behavior: Issues of representativeness and validity

Data were gathered from videotaped recordings of two preschool children engaged in unstructured free play over 12 days each. Observers coded behavior from the videotapes and completed a behavior rating scale for each child after every two observation sessions. Teachers also completed two behavior rating scales per child. Results indicated that at least three 30‐min observation sessions were required to reliably represent a child's overall behavior. Moderate correlations were obtained when observations were compared with teachers' and observers' own ratings, indicating the behavior rating scale did an adequate job of reflecting actual observed behavior. The implications of these results for researchers and practitioners are discussed. © 2005 Wiley Periodicals, Inc. Psychol Schs 42: 13–26, 2005.     

Identification and Evaluation of Local Item Dependencies in the Medical College Admissions Test

Measurement specialists routinely assume examinee responses to test items are independent of one another. However, previous research has shown that many contemporary tests contain item dependencies and not accounting for these dependencies leads to misleading estimates of item, test, and ability parameters. The goals of the study were (a) to review methods for detecting local item dependence (LID), (b) to discuss the use of testlets to account for LID in context-dependent item sets, (c) to apply LID detection methods and testlet-based item calibrations to data from a large-scale, high-stakes admissions test, and (d) to evaluate the results with respect to test score reliability and examinee proficiency estimation. Item dependencies were found in the test and these were due to test speededness or context dependence (related to passage structure). Also, the results highlight that steps taken to correct for the presence of LID and obtain less biased reliability estimates may impact on the estimation of examinee proficiency. The practical effects of the presence of LID on passage-based tests are discussed, as are issues regarding how to calibrate context-dependent item sets using item response theory.     

Investigating teachers’ professional learning in an advanced Master’s degree programme

This study examined how multiple measures can be used to study experienced teachers’ learning. The study was conducted in an advanced Master’s degree programme, aligned with the National Board for Professional Teaching Standards in the United States. The programmatic features and key learning experiences found in the programme are described and connected to the multiple measures used to investigate teachers’ professional learning. Results of the study indicated that multiple measures can be used to examine a programme’s effects on teacher learning; prompted reflections can provide evidence of a programme’s influence on teacher thinking; and programme structure and content are important elements to consider when designing and assessing programmes for experienced teachers. This study also addresses how building a programme around measurable outcomes and then examining the results through multiple measures is an important link in understanding teacher learning.     

Pre‐election perceptions of politicians and their promises as a function of the reference group match between speaker and listener

The Categorization‐Attribution‐Matching or CAM model of persuasion was tested in a field experiment, using an actual election to provide a natural manipulation of reference group similarity‐dissimilarity between speaker and audience. Just prior to the election, 344 Ss rated a set of campaign proposals, which were attributed either to the incumbent Prime Minister of Australia, or to the Leader of the Opposition. Half of the Ss received an unsupported, and half received a supported version of the message, thereby manipulating information content. Ss also rated the speaker, and indicated how they intended to vote. As predicted, speakers and speeches were rated as more credible and persuasive respectively, in the conditions where the political affiliation between source and target was matched, than in the mismatched conditions. And as predicted, the provision of additional information did not make a speaker more credible or a message more persuasive, when reference group salience was high.
