Elementary-age children’s conceptions about mathematics utility and their home-based mathematics engagement

Integrating multiple theoretical frameworks, the authors examined rising first- to fourth-grade students’ mathematics utility conceptions—their knowledge and beliefs about the usefulness of mathematics, home-based mathematics engagement, and grade-level differences in mathematics utility conceptions and home engagement. Most children viewed mathematics as heavily focused on low-level mathematics operations and as learned and used primarily in school. Older children showed more awareness of mathematics as part of daily living, but still viewed mathematics as mostly school-based—more so than their younger counterparts. Results suggest that awareness of mathematics in daily life may be associated with children’s mathematics utility value (perceived usefulness of mathematics). Although children engaged in activities at home with the potential to foster mathematics development, the frequency of engagement was not related to their awareness of mathematics in daily activities. Thus, there may be untapped opportunities for young children to connect the mathematics they learn in school to their daily life.     

Do deaf and hard of hearing youth need antitobacco education?

Little research has focused on tobacco use among deaf and hard of hearing youth. Findings are reported from a first-ever tobacco-related survey, completed by 226 California middle and high school students using either a written questionnaire or the Interactive Video Questionnaire, an interactive multimedia computer video technology. Rates for current smoking (3.1%), ever smoking (45.1%), and multiple types of tobacco use (10.6%) were found to be lower than among high school students generally; mainstreamed students were likelier to have ever tried smoking than their deaf school peers (57.8% vs. 31.8%). No statistically significant associations were found between ever smoking and race/ethnicity, gender, school performance, or prelingual vs. postlingual deafening; a quarter of the sample experienced occasional peer pressure to use tobacco products. Tobacco use covariates, exposure to cigarette marketing and antismoking programming, and tobacco education needs of deaf and hard of hearing youth are discussed.     

Promoting Middle School Students’ Understandings of Molecular Genetics

Genetics is the cornerstone of modern biology and understanding genetics is a critical aspect of scientific literacy. Research has shown, however, that many high school graduates lack fundamental understandings in genetics necessary to make informed decisions or to participate in public debates over emerging technologies in molecular genetics. Currently, much of genetics instruction occurs at the high school level. However, recent policy reports suggest that we may need to begin introducing aspects of core concepts in earlier grades and to successively develop students’ understandings of these concepts in subsequent grades. Given the paucity of research about genetics learning at the middle school level, we know very little about what students in earlier grades are capable of reasoning about in this domain. In this paper, we discuss a research study aimed at fostering deeper understandings of molecular genetics at the middle school level. As part of the research we designed a two-week model-based inquiry unit implemented in two 7th grade classrooms (N = 135). We describe our instructional design and report results based on analysis of pre/post assessments and written artifacts of the unit. Our findings suggest that middle school students can develop: (a) a view of genes as productive instructions for proteins, (b) an understanding of the role of proteins in mediating genetic effects, and (c) can use this knowledge to reason about a novel genetic phenomena. However, there were significant differences in the learning gains in both classrooms and we provide speculative explanations of what may have caused these differences.     

Probeware and Handhelds in Elementary and Middle School Science

This paper reports a test on the feasibility and educational value of probeware and associated instructional materials in middle school science education. We addressed feasibility through consideration of costs, teacher professional development, and instructional design. In order to test our approach, we developed 2 middle school science curriculum units, 6 low-cost probes that interface between handheld Palm computers, and CCLabBook software for the Palms that presents the curriculum, interfaces with the probes for data collection and visualization, and supports guided exploration. The materials were tested by 30 teachers in the first year, and in a follow-up study by 8 of those teachers the second year. We found that teachers were able to conduct the investigations successfully in their classrooms, and that student learning was enhanced through the use of the probes and handhelds. Specifically, students experienced the physical correlation between phenomenon and modeling, which helped them to develop understanding and to confront misconceptions.     

Establishing Media Partnerships in Crisis Response

Social protests in the United States of America (U.S.) are increasing in frequency, including the Dakota Access pipeline protests, the Women’s March in 2017 and 2018, and March for our Lives. Thousands of other protests have also emerged across digital platforms and in interpersonal contexts. This study explores the identity work processes individuals navigate as they engage with or avoid social protest. I conducted interviews with self-identified protesters who discussed the complexities of their experiences. Using CTI and identity gaps, dialogical wisdom are introduced to deepen this analysis. This scholarship provides insights for those interested in the interplay between individual identities and protest, as well how multiple identities and the gaps between them can address conflict.     

Reading Difficulties in Adult Deaf Readers of French: Phonological Codes,Not Guilty!

Deaf people often achieve low levels of reading skills. The hypothesis that the use of phonological codes is associated with good reading skills in deaf readers is not yet fully supported in the literature. We investigated skilled and less skilled adult deaf readers' use of orthographic and phonological codes in reading. Experiment 1 used a masked priming paradigm to investigate automatic use of these codes during visual word processing. Experiment 2 used a serial recall task to determine whether orthographic and phonological codes are used to maintain words in memory. Skilled hearing, skilled deaf, and less skilled deaf readers used orthographic codes during word recognition and recall, but only skilled hearing readers relied on phonological codes during these tasks. It is important to note that skilled and less skilled deaf readers performed similarly in both tasks, indicating that reading difficulties in deaf adults may not be linked to the activation of phonological codes during reading.     

Using a video-based curriculum to develop a reflective stance in prospective mathematics teachers

Although video cases are increasingly being used in teacher education as a means of situating learning and developing habits of reflection, there has been little evidence of the outcomes of such use. This study investigates the effects of using a coherent video-case curriculum in a university mathematics methods course by addressing two issues: (1) how the use of a video-case curriculum affects the reflective stance of prospective teachers (PTs); and (2) the extent to which a reflective stance developed while reflecting on other teachers’ practice transfers for reflecting on one’s own practice. Data sources include videotapes of course sessions and PTs’ written work from a middle school mathematics methods course that used a video-case curriculum as a major instructional tool. Both qualitative and quantitative analytical methods were used, including comparative and chi-square contingency table analyses. The PTs in this study showed changes in their level of reflection, their tendency to ground their analyses in evidence, and their focus on student thinking. In particular, they began to analyze teaching in terms of how it affects student thinking, to consider multiple interpretations of student thinking, and to develop a more tentative stance of inquiry. More significantly, the reflective stance developed via the video curriculum transferred to the PTs’ self-reflection in a course field experience. The results of this study speak to the power of using a video-case curriculum as a means of developing a reflective stance in prospective mathematics teachers.
