Understanding inclusive STEM high schools as opportunity structures for underrepresented students: Critical components

Inclusive STEM high schools (ISHSs) can be viewed as opportunity structures for students underrepresented in STEM. By opportunity structures, we mean an education that provides not only access to high quality STEM curriculum and instruction or “opportunity to learn,” but also the capacity to create learning environments where students can build STEM social capital and the dispositions, knowledge, skills, and networks to be successful in STEM college majors and careers. This is a cross‐case analysis of case studies that describe the design and implementation of eight “exemplar” ISHSs. Beginning with 10 hypothesized critical components, we found evidence for all 10, but present in unique patterns of prominence, depending on the school context. Further inductive analysis located an additional four emergent critical components that complete the picture of how these successful ISHSs were able to achieve their goals. Importantly, across schools, four components stood out as foundational: a flexible and autonomous administrative structure; a college‐preparatory, STEM‐focused curriculum for all; well‐prepared STEM teachers and professionalized teaching staffs; and supports for students in underrepresented groups. Although many of the critical components found in the ISHSs are also found in the school reform literature, these schools also had characteristics unique to STEM education. This paper is important in understanding STEM high schools as opportunity structures and as a school reform alternative that can help solve equity and social mobility gaps in STEM.     

From failure to success: Changing the experience of adult learners of mathematics

For the last few years, the author has been part of a team developing a mathematics course for students most of whom are women, many of whom are black and all of whom are attempting to gain entry to a teacher-training course by successfully completing a one year re-entry course. It is a requirement that teacher-training students should have attained a suitable standard in mathematics. Further Education colleges where re-entry courses are sited have a sad history of student failure in mathematics. The theoretical environment in which the development of this course took place is described in order to place the course in context. In particular, attention is drawn to the re-definition of mathematics which encourages student enquiry and experimentation in order to establish a basis for understanding the subject, and to the teaching/learning model which creates an environment of respect and confidence. The roles of students and staff in a learning environment of this kind are discussed. Particular attention is paid to the attitudes and feelings of the students and the effects on their expectations.     

Direct instruction revisited: A key model for instructional technology

Rooted in behavioral theory, particularly the radical or selectivist behaviorism of B.F. Skinner (1953, 1954, 1966, 1968, 1974), the direct instruction (DI) approach to teaching is now well into its third decade of influencing curriculum, instruction, and research. It is also in its third decade of controversy. Our purpose is to present the DI model with the notion that the designer can and should use the model effectively based on appropriate assessment of the learners, content, context, and task at hand. To accomplish our goal, we begin with a general discussion of the basic DI framework, followed by a summary of the major DI models that have been used in live instructional contexts. We then shift to a review of how DI has been used in technology-based learning environments. Finally, we conclude with a look into the future of DI.     

A social learning theory comparison of the sexual victimization of adolescent sexual offenders and nonsexual offending male delinquents

OBJECTIVE: This paper tests hypotheses based on Garland and Dougher's (1990) formulation of the "victim to victimizer" relationship which is a social learning theory etiological approach to adolescent sexual offending. METHOD: Two hundred sixteen adolescent sexually victimized sexual offenders and 93 adolescent sexually victimized nonsexual offending delinquents from three Michigan sexual offender treatment facilities participated in an anonymous cross-sectional survey regarding their sexual victimization and offending as well as a social desirability measure. RESULTS: When comparing the two groups, nonsexually offending delinquents and sexually offending delinquents, the latter were found to have: closer relationships with their perpetrators; a higher chance of having a male perpetrator(s); a longer duration of sexual victimization; more forceful sexual victimization; and the experience of penetration as part of their sexual victimization. Logistic regression showed that the gender of the perpetrators being both male and female and the forcefulness of the perpetrators were the best predictors of being in the sexual offender group. CONCLUSIONS: The social learning theory hypotheses were generally supported. Further multivariate research on this theory is warranted.     

Sampling knowledge and understanding: how long should a test be?

Many academic tests (e.g. short‐answer and multiple‐choice) sample required knowledge with questions scoring 0 or 1 (dichotomous scoring). Few textbooks give useful guidance on the length of test needed to do this reliably. Posey's binomial error model of 1932 provides the best starting point, but allows neither for heterogeneity of question difficulty and discriminatory power nor for students' uneven spread of knowledge. Even with these taken into account, it appears that tests of 30–60 items, as commonly used, must generally be far from adequate. No exact test length can be specified as ‘just sufficient’, but the tests of 300 items that some students take are not extravagantly long. The effects on reliability of some particular test forms and practices are discussed.     

Undergraduate Experiences of Division I Athlete Science,Technology, Engineering,and Mathematics (STEM) Graduates

Employing the conceptual model developed by Comeaux and Harrison (Coll Stud Aff J 30(1):75–87, 2011), this study explored the undergraduate experience of Division I athlete STEM graduates. Data collection involved 17 in-depth interviews with former athletes at two research-intensive, public institutions. Results revealed that pre-college characteristics, involvement in purposeful STEM-related activities, and sport participation, as well as academic support and guidance within athletic departments, play important roles in shaping the experiences of athletes who earn STEM degrees. Implications for student affairs professionals, faculty, and others who frequently interact with college athletes and are committed to creating more equitable educational environments are discussed.     

Environmental learning in online social networks: adopting environmentally responsible behaviors

Online social networks are increasingly important information and communication tools for young people and for the environmental movement. Networks may provide the motivation for young adults to increase environmental behaviors by increasing their knowledge of environmental issues and of the specific actions they can take to reduce greenhouse gas emissions. This study examined an application within Facebook.com – the largest online social network in the world – that allowed users to post climate change news stories from other websites and comment on those stories. A survey revealed that users of the social networking application reported above average knowledge of climate change science and that self‐reported environmental behaviors increased during young people's involvement with the Facebook application. Focus groups indicated that peer role modeling through interaction on the site motivated pro‐environmental behaviors, that is, behavior that seeks to minimize the negative impact of one's actions on the natural and built world. Participation in a community of like‐minded users spurred many participants to learn more about climate change and do more to limit its impact.     

Recignising commonalities and reconciling differences in mathematics education

Data from a study of the practices of research mathematicians are used to highlight an exploration of commonalities across and differences between learners in mathematics classrooms. Such commonalities and differences are, it is claimed, central to a teacher's understandings of how to address her role and responsibilities. Commonalities discussed are those between learners,across mathematics and between communities of practice. Differences between syllabus and practice, between school mathematics,mathematics in the world, and academic mathematics and, finally, between members of the different communities of students,teachers of mathematics, mathematics educators, and mathematicians are explored. This revised version was published online in July 2006 with corrections to the Cover Date.     

Lies and Truth: A Study of the Development of the Concept

This study examined the developmental questions of when children begin to use the terms lie and truth, how they understand them, and when their understanding approaches that of adults. 150 subjects in 5 groups (nursery schoolers, preschoolers, first graders, fifth graders, and adults) were presented a series of 8 short puppet plays that systematically varied the presence of absence of the 3 prototype elements: factuality of a statement, the speaker's belief in the factuality or falsity of the statement, and the speaker's intent to deceive the listeners. The interactions of age, factuality, and belief most fully accounted for the use of the terms lie and truth. Persons at different ages differentially weighed the prototypic elements. Responses of fifth graders were transitional between those of the younger children and adults. The results are interpreted as supporting the development of definitional prototypes for these moral concepts.
