Factors influencing success in introductory college chemistry

Previous research has found a wide range of predictors of student performance in introductory college chemistry. These predictors are associated with both the students' backgrounds and their high school learning experiences. The purpose of this research study was to examine the link between high school chemistry pedagogical experiences and performance in introductory college chemistry while accounting for individual educational and demographic differences. The researchers surveyed 1531 students enrolled in first‐semester introductory college chemistry courses for science and engineering majors at 12 different U.S. colleges and universities. Using multiple regression analysis, the researchers uncovered several interesting high school pedagogical experiences that appeared to be linked with varying levels of performance in college chemistry. Most notably, the researchers found that repeating chemistry labs for understanding was associated with higher student grades, whereas overemphasis on lab procedure in high school chemistry was associated with lower grades in college. These results suggest that high school teachers' pedagogical choices may have a link to future student performance. © 2005 Wiley Periodicals, Inc. J Res Sci Teach 42: 987–1012, 2005     

The literature of educational psychology and the literature used by writers in educational psychology

Using Psychological Abstracts as the source of the original sample (“first-level”), various characteristics of the literature of educational psychology are compared with the characteristics of a “second-level” literature (defined as the literature that the first level cites). In particular, the scatter (dispersion) of periodical articles over periodical titles is looked at for both levels. The journals most cited within the literature of educational psychology are identified.     

Culturally responsive peacebuilding pedagogy: a case study of Fambul Tok Peace Clubs in conflict-affected Sierre Leone

Recent research on the peace-promoting agency of teachers in conflict-affected contexts has critiqued the dominance of a menu of curriculum initiatives circulated within aid organizations which ignore or dismiss indigenous cultural resources available within local communities. On the other hand, the turn to local culture in peacebuilding interventions has also been critiqued for idealizing the local. This paper presents a case study of the work of Fambul Tok Peace Clubs in conflict-affected Sierra Leone which aim to support teachers in drawing on local practices, rituals and symbols. Using an interpretative approach, alert to the meanings teachers ascribe to their pedagogical practices, it finds that teachers respond to local culture in multiple, sometimes contradictory ways. These range from celebration of indigenous practices as resources for conflict resolution that resonate with their pupils and communities to critique of their oppressive gender norms and inability to address structural drivers of conflict.     

University class size: Is smaller better?

This study investigates the relationship between class size and achievement at the college level. Recent meta-analyses have found a strong relationship between class size and student achievement, but few of the studies examined class size larger than 40 or university-age populations. This analysis examines a university's testing-center data-archives representing 305 sections from 24 different courses. Section sizes ranged from 13 to 1,006. A total of 16,230 test scores were analyzed. The results of this investigation reveal that at the college level, class size may be less important an influence on student achievement than some educators have thought.     

Flavor- vs. tone-cued shock avoidance

In a direct comparison, flavor-cued rats learned to avoid shock in a two-way shuttlebox as well as, or better than, tone-cued rats. These results stand in contrast to the prevalent view that rats encounter difficulty in forming flavor-shock, but not tone-shock, associations. In attempting to account for this contrast, we note that experiments revealing cue-modality specificity employ an aversion paradigm and record ingestive behavior. It is argued that both the paradigm and the dependent variable are inappropriate for assessing shock-avoidance learning, and that cue-modality specificity in such a setting reflects paradigm and response choice rather than a general characteristic of rats.     

Evaluating the quality of peer and self evaluations as measures of student contributions to group projects

ABSTRACT

Educators in higher education commonly use peer and self evaluations to help assess student performance on group projects. Although these evaluations provide multiple benefits, many educators are wary of using them due to concerns about their quality. This study addresses three questions debated in the literature regarding the quality of these assessments. How much do students differentiate among peer contributions through their ratings? How reliable are peer ratings? How much agreement exists between peer and self ratings? Although these questions have been addressed to varying degrees in past work, their answers have been far from settled. While many studies focus on just one of the questions, this study’s data make it possible to address all three questions for the same group of students as well as examine each question by student performance level. The evaluations assessed in this study were completed by a large number of students under conditions associated with obtaining more valid and reliable ratings. Overall, the results provide support for using peer and self evaluations to help assess student contributions to group projects. Peer ratings were largely reliable as group members generally agreed on the scores given to their peers. In addition, most students differentiated among group member contributions through their ratings. Students also tended to rate themselves higher than their peers rated them. This study has implications for how peer and self evaluations can be most effectively used by educators to measure student performance in group work.     

The attainment of doctoral degrees at Flemish Universities: a survival analysis

This paper examines the propensity to attain a Ph.D. degree at the five largest universities in Flanders, the Dutch speaking part of Belgium. It provides insight into the rate at which junior scholars appointed at the universities involved attained their Ph.D.-degree, and the duration of the doctoral training period. Cox’s regression model was applied to statistically analyse the influence of a number of ‘demographic’ and ‘merit’ variables, and variables related to funding source and type of appointment of the junior scholarly staff. Large differences in Ph.D. durations and attainment rates were found across funding sources, research disciplines and types of appointments. The policy background and implications are discussed briefly.     

Teaching Quality Across School Settings

Districts are increasingly making personnel decisions based on teachers’ impact on student-achievement gains and classroom observations. In some schools, however, a teacher’s practices and their students’ achievement may reflect not just individual but collaborative efforts. In other settings, teachers’ instruction benefits less from the insights and support of their colleagues. This article analyzes multiple measures of teacher and teaching quality for 24 language arts teachers in New York City who teach in different types of school environments. Teachers in different value-added quartiles were observed and scored using two protocols, PLATO and CLASS. Schools were categorized as more and less functional using Department of Education environment grades. To compare the practices of higher and lower value-added teachers in more and less functional schools, we conduct MANOVAs of observation scores and use qualitative coding of field notes. We find value-added measures and observation protocols provide confirmatory information in less functional schools but provide contradictory information about teacher quality in more functional schools. Implications for teacher education, policy, and future research are discussed.
