“No Excuses” Charter Schools: A Meta-Analysis of the Experimental Evidence on Student Achievement

Many most well-known charter schools in the United States use a “No Excuses” approach. We conduct the first meta-analysis of the achievement impacts of No Excuses charter schools, focusing on experimental, lottery-based studies. We estimate that No Excuses charter schools increase student math and literacy achievement by 0.25 and 0.17, respectively, for approximately each year of attendance. These are large and meaningful gains. Moreover, these effects are substantially larger than those of attending other kinds of charter schools. We discuss policy implications and offer necessary caveats.     

Associations Between Father Absence and Age of First Sexual Intercourse

Children raised without a biological father in the household have earlier average ages of first sexual intercourse than children raised in father-present households. Competing theoretical perspectives have attributed this either to effects of father absence on socialization and physical maturation or to nonrandom selection of children predisposed for early sexual intercourse into father-absent households. Genetically informative analyses of the children of sister dyads ( N  = 1,382, aged 14–21 years) support the selection hypothesis: This association seems attributable to confounded risks, most likely genetic in origin, which correlated both with likelihood of father absence and early sexual behavior. This holds implications for environmental theories of maturation and suggests that previous research may have inadvertently overestimated the role of family structure in reproductive maturation.     

Responding to Students’ Learning Preferences in Chemistry

This paper reports on a teacher’s and his students’ responsiveness to a new tetrahedral-oriented (Mahaffy in J Chem Educ 83(1):49–55, 2006) curriculum requiring more discursive classroom practices in the teaching of chemistry. In this instrumental case study, we identify the intentions of this learner-centered curriculum and a teacher’s development in response to this curriculum. We also explore the tensions this teacher experiences as students subsequently respond to his adjusted teaching. We use a Chemistry Teacher Inventory (Lewthwaite and Wiebe in Res Sci Educ 40(11):667-689, 2011; Lewthwaite and Wiebe in Can J Math Sci Technol Educ 12(1):36–61, 2012; Lewthwaite in Chem Educ Res Pract. doi:10.1039/C3RP00122A, 2014) to assist the teacher in monitoring how he teaches and how he would like to improve his teaching. We also use a student form of the instrument, the Chemistry Classroom Inventory and Classroom Observation Protocol (Lewthwaite and Wiebe 2011) to verify the teacher’s teaching and perception of student preferences for his teaching especially in terms of the discursive processes the curriculum encourages. By so doing, the teacher is able to use both sets of data as a foundation for critical reflection and work towards resolution of the incongruence in data arising from students’ preferred learning orientations and his teaching aspirations. Implications of this study in regards to the authority of students’ voice in triggering teachers’ pedagogical change and the adjustments in ‘teachering’ and ‘studenting’ required by such curricula are considered.     

“The Scientific Method” as Myth and Ideal

“The Scientific Method” as it has been portrayed in popular and introductory contexts has been declared a myth. The variation that one finds in introductory presentations of “The Scientific Method” is explained by the fact that there is no canonical account among historians and philosophers of science. What, in particular, is wrong with “The Scientific Method”? This essay provides a fairly comprehensive survey of shortcomings of “The Scientific Method”. Included are corrections to several misconceptions that often accompany such presentations. Rather than treating “The Scientific Method” as a useful approximation or an ideal, the myth should be discarded. Lessons can be learned for introductory pedagogical contexts from considering the shortcomings of the myth.     

Family Structure Changes During High School and College Selectivity

Research has shown that family structure changes negatively influence educational attainment, but they overlook qualitative distinctions in college choice, such as college selectivity. Yet, college choice research has largely focused on static measures of family structure, failing to account for year-to-year family structure changes that occur during high school. We merge literature in family and college choice to investigate the role of family-life events on college choice. We found family structure changes that occur early and late in high school influence the selectivity of the college where a student applies, and this relation persists in spite of controls for race, gender, family background, and pre-high school family structures. Including educational expectations, parent–student discussions, and coursework rigor account for the negative association between family structure changes during high school and the selectivity of the college where a student applies. However, late family structure changes during high school continue to correlate negatively with a student’s college enrollment, potentially reflecting realities and financial burdens of attending college, especially selective colleges.     

An Experimental Study of the Internal Consistency of Judgments Made in Bookmark Standard Setting

Validating performance standards is challenging and complex. Because of the difficulties associated with collecting evidence related to external criteria, validity arguments rely heavily on evidence related to internal criteria—especially evidence that expert judgments are internally consistent. Given its importance, it is somewhat surprising that evidence of this kind has rarely been published in the context of the widely used bookmark standard‐setting procedure. In this article we examined the effect of ordered item booklet difficulty on content experts’ bookmark judgments. If panelists make internally consistent judgments, their resultant cut scores should be unaffected by the difficulty of their respective booklets. This internal consistency was not observed: the results suggest that substantial systematic differences in the resultant cut scores can arise when the difficulty of the ordered item booklets varies. These findings raise questions about the ability of content experts to make the judgments required by the bookmark procedure.     

Teaching a Selection of Heaney’s Troubles Poetry to Upper Post-primary Pupils in Northern Ireland’s Divided Schools: Educational Contexts and Pedagogical Opportunities

Centred on a carefully chosen selection of Heaney’s Troubles poems, this paper explores pedagogical opportunities that the poems present in the context of upper post-primary classrooms in Northern Ireland’s divided schools. Five poems are evaluated in total. These are: ‘The Other Side’, ‘A Constable calls’, ‘The Toome Road’, ‘The Strand at Lough Beg’ and ‘An Ulster Twilight’. While these five poems represent only a small selection of Heaney’s Troubles poems, they nonetheless cover an interesting spectrum in terms of their politico-cultural perspectives. The analysis of the poems focuses on exploring how teachers could use the poems to enable pupils to examine their traditional identities and allegiances and perhaps re-evaluate them in the light of new insights provided by the poems. While suggestions for this pedagogical exploration is at the heart of the paper, the early section establishes some relevant theoretical and educational contexts and the concluding section situates the paper in the context of previous, related curricular initiatives with Northern Ireland. It is to be hoped, finally, that the curricular initiative proposed by the paper could contribute, if even in a small way, to the ongoing search for peace and reconciliation between Northern Ireland’s two main, and still divided, communities.     

Continuity and change in levels of externalizing behavior in school of children from economically disadvantaged families

This study used a person-centered approach to understand continuity and change in the externalizing behavior of children from economically disadvantaged families (N = 134). Groups of children differed in showing high levels of externalizing behavior in first grade (7 years old) that persisted (persistent problem) or decreased (improver) in third grade (9 years old) and low levels in first grade that were stable (unproblematic) or increased (new problem) in third grade. The results showed that verbal ability, behavioral impulsivity, parent maladjustment, and harsh parenting distinguished the persistent problem and unproblematic groups. Family instability was associated with change for the improver and new problem groups. The results suggest the importance of examining changes in the early adjustment to school for children from economically disadvantaged families.     

Factor structure of the pictorial scale of perceived competence and social acceptance with two pre-elementary samples

Competing models of the factorial structure of the Pictorial Scale of Perceived Competence and Social Acceptance (PSPCSA) were tested for fit using multisample confirmatory factor analysis. The best fitting model was tested for invariance (a) across samples of middle-class (n = 251) and economically disadvantaged (Head Start, n = 117) kindergarten children (whose ages ranged from 67 to 86 months), and (b) over time (at the end of preschool and kindergarten) for the Head Start sample. For kindergarten children, regardless of socioeconomic status, the factor structure of the PSPCSA was consistent with the 2-factor model of Competence and Acceptance. This model also fit reasonably well for Head Start children at the end of their preschool year. However, in addition to providing broad support for the dimensionality of the measure, our findings highlight important concerns about the PSPCSA.
