Understanding science teaching effectiveness: examining how science-specific and generic instructional practices relate to student achievement in secondary science classrooms

ABSTRACT

In order to create conditions for students’ meaningful and rigorous intellectual engagement in science classrooms, it is critically important to help science teachers learn which strategies and approaches can be used best to develop students’ scientific literacy. Better understanding how science teachers’ instructional practices relate to student achievement can provide teachers with beneficial information about how to best engage their students in meaningful science learning. To address this need, this study examined the instructional practices that 99 secondary biology teachers used in their classrooms and employed regression to determine which instructional practices are predictive of students’ science achievement. Results revealed that the secondary science teachers who had well-managed classroom environments and who provided opportunities for their students to engage in student-directed investigation-related experiences were more likely to have increased student outcomes, as determined by teachers’ value-added measures. These findings suggest that attending to both generic and subject-specific aspects of science teachers’ instructional practice is important for understanding the underlying mechanisms that result in more effective science instruction in secondary classrooms. Implications about the use of these observational measures within teacher evaluation systems are discussed.     

Athletic Identity of Community College Student Athletes: Issues for Counseling

Community college student athletes are unique in their setting in the world of college student athletes. Many compete for the love of their sport, while others have aspirations for transferring to major colleges to continue their participation. The current study made use of the Athletic Identity Measurement Scale with a sample of nearly 400 community college student athletes to begin to understand some of the unique counseling needs of these students. These needs are highlighted by the need for student athletes to have a mentally healthy perspective on the role of sport in life and the relationship of sports to academic pursuits. Community college administrators need to use caution in balancing student development with mental health concerns.     

The effects of different types of text and individual differences on view complexity about genetically modified organisms

ABSTRACT

View change about socio-scientific issues has been well studied in the literature, but the change in the complexity of those views has not. In the current study, the change in the complexity of views about a specific scientific topic (i.e. genetically modified organisms; GMOs) and use of evidence in explaining those views was examined in relation to individual factors and type of text (informational, persuasive, or narrative). Undergraduate students completed measures of their prior views about GMOs their epistemic beliefs about the nature of science, and activities related to food consumption. Participants then read either an informational, persuasive, or narrative passage about GMOs and again answered a question related to their views about GMOs. Participants who read the persuasive passage decreased in the complexity of their views, while those who read the narrative and expository passage increased in the complexity of their views. Additionally, while cultural activities related to the complexity of individuals’ views during the pretest, these significant differences were not evident at posttest after the text intervention. These findings can be used to help scientists and teachers better understand how to communicate information critical to understanding complex science and environmental issues to the public and their students.     

The Structure of Phonological Processing and Its Relationship to Basic Reading

We investigated various structural models of phonological processing and the relationship of phonological processing abilities to basic reading. Data were collected on 116 kindergarten and first grade students. The specific ability model, which included phonological awareness, phonological memory, and rapid automatized naming as separate abilities, had the strongest fit to the data. Of the specific phonological processing abilities, rapid automatized naming was least associated with a second-order factor. Phonological awareness and rapid automatized naming accounted for variance in word reading, although the latter demonstrated limited practical utility. Theoretical and practical implications are discussed.     

Critical race and LatCrit theory and method: Counter-storytelling

Using critical race theory as a framework, the article utilizes counter-storytelling to examine the different forms of racial and gender discrimination experienced by Chicana and Chicano graduate students. After describing the critical race theory framework and counter-storytelling method, the article moves to a story of two composite and data-driven characters, Professor Leticia Garcia and graduate student Esperanza Gonzalez. Various theoretical and conceptual issues such as self-doubt, survivor guilt, impostor syndrome, and invisibility are woven into Esperanza's graduate school and Professor Garcia's pre-tenure experiences.     

Pedagogy and the problem of difference: On reading community in The Darker Side of Black

This paper examines the responses of two groups of high school students to Isaac Julien's film The Darker Side of Black and theorizes what these responses might suggest for how students imagine and argue for community. It explores the tension that is produced as students argue for community as continuous and stable in the face of discontinuity and difference in the diaspora. The paper raises the possibilities for how pedagogy may occupy the space of tension that emerges from competing notions of community. It calls attention to the pedagogic constraints that come from the practice of privileging difference between communities, which might well compromise engagement with difference within. The trope of culture as the attribute of social groups that has come to structure debates on multicultural and antiracist education is critiqued.
