A prospective study of the relationship between phonological,semantic and syntactic skills and specific reading disability

Although it is well established that a relationship exists between specific reading disability and spoken language difficulties, the nature of that relationship remains controversial. In the study reported here, the performance of poor readers was firstly compared with that of matched good readers on a series of spoken and written language tasks on three assessment trials 12 months apart, and secondly to that of younger average readers. Five experimental tasks were used to measure the readers' phonological processing skills, and three subtests from the CELF-R were selected to measure the students' syntactic and semantic skills. Reading accuracy and comprehension ability were assessed by the Neale Analysis of Reading Ability-Revised. The results showed that 8–10-year-old poor readers performed poorly in all three linguistic areas concurrently, and that these difficulties persisted. However, the important finding from this study was that while the good readers demonstrated no significant difference between their phonological processing skills and their semantic/syntactic skills, the poor readers' ability did differ according to skill area. The poor readers' phonological processing skills appeared to be particularly impaired, a finding which was further enhanced by results from the reading-match comparison. The results are discussed in terms of current theories of reading disability.     

Enhancement of Mentor Selection Using the Ideal Mentor Scale

Doctoral students seeking faculty mentors have few tools available to assist them. The Ideal Mentor Scale (IMS) is a new measure designed to help graduate students consider the qualities they as individuals most value in a potential mentor. Ph.D. students at 3 different universities (Ns = 82, 250, 380) contributed to the development and cross-validation of the 34-item IMS. Item frequencies indicated that 2 universal qualities were central to graduate students' definitions of a mentor: communication skills and provision of feedback. Principal factor analysis of the IMS indicated that 3 individual differences dimensions reliably underlaid graduate students' importance ratings of mentor attributes: Integrity, Guidance, and Relationship. In one sample, Guidance and Relationship were significantly related to student satisfaction with their mentor. The IMS is an assessment tool that could individualize the initiation and maintenance of mentoring relationships, enhance communication, and ultimately improve the satisfaction of students with their doctoral education.     

Elementary Teachers’ Selection and Use of Visual Models

As science grows in complexity, science teachers face an increasing challenge of helping students interpret models that represent complex science systems. Little is known about how teachers select and use models when planning lessons. This mixed methods study investigated the pedagogical approaches and visual models used by elementary in-service and preservice teachers in the development of a science lesson about a complex system (e.g., water cycle). Sixty-seven elementary in-service and 69 elementary preservice teachers completed a card sort task designed to document the types of visual models (e.g., images) that teachers choose when planning science instruction. Quantitative and qualitative analyses were conducted to analyze the card sort task. Semistructured interviews were conducted with a subsample of teachers to elicit the rationale for image selection. Results from this study showed that both experienced in-service teachers and novice preservice teachers tended to select similar models and use similar rationales for images to be used in lessons. Teachers tended to select models that were aesthetically pleasing and simple in design and illustrated specific elements of the water cycle. The results also showed that teachers were not likely to select images that represented the less obvious dimensions of the water cycle. Furthermore, teachers selected visual models more as a pedagogical tool to illustrate specific elements of the water cycle and less often as a tool to promote student learning related to complex systems.     

Exploring undergraduates' understanding of photosynthesis using diagnostic question clusters

We present a diagnostic question cluster (DQC) that assesses undergraduates' thinking about photosynthesis. This assessment tool is not designed to identify individual misconceptions. Rather, it is focused on students' abilities to apply basic concepts about photosynthesis by reasoning with a coordinated set of practices based on a few scientific principles: conservation of matter, conservation of energy, and the hierarchical nature of biological systems. Data on students' responses to the cluster items and uses of some of the questions in multiple-choice, multiple-true/false, and essay formats are compared. A cross-over study indicates that the multiple-true/false format shows promise as a machine-gradable format that identifies students who have a mixture of accurate and inaccurate ideas. In addition, interviews with students about their choices on three multiple-choice questions reveal the fragility of students' understanding. Collectively, the data show that many undergraduates lack both a basic understanding of the role of photosynthesis in plant metabolism and the ability to reason with scientific principles when learning new content. Implications for instruction are discussed.     

How Moroccan mothers and fathers view child development and their role in their children's education

Despite the documented importance of parental engagement in early learning, little is known about how parents in the Middle East and North Africa understand child development. To inform the literature, a small-scale study involving four focus groups was conducted with parents of children aged six years and under living in Casablanca. The purpose of this study was to explore parents' understanding of and support for their children's early development. Results reveal that parents see a vital role for themselves in their children's upbringing as supporters and nurturers, but little role as teachers. Across different education and income levels, parents in this small-scale qualitative study believe that children's experiences in their first years of life do not affect their longer-term intellectual development or school success and see little value in early intellectual stimulation or formal preschool education. Our results suggest that parents need to understand their role as their child's first educators. Also, it is essential that parents are taught how to promote their children's early cognitive development without undermining their nurturing roles.     

Teachers’ Concepts of Spatial Scale: An international comparison

Metric scale is an important concept taught as part of science curricula across different countries. This study explored metric and relative (body-length) scale concepts of inservice (N?=?92) and preservice (N?=?134) teachers from Austria, and Taiwan, and their concepts were compared with those of teachers from the USA. Participants completed three assessments: the Scale Anchoring Objects (SAO), Scale of Objects Questionnaire (SOQ), and a subsample of participants were interviewed with the Learning Scale Interview. A Rasch analysis was conducted with the SAO and SOQ and results showed that the Rasch model held for these assessments, indicating that there is an underlying common dimension to understanding scale. Further analyses showed that accuracy of knowledge of scale measured by the SAO and SOQ was not related to professional experience. There were significant differences in teachers’ accuracy of scale concepts by nationality. This was true for both metric and body-length SAO assessments. Post hoc comparisons showed that the Austrian and Taiwanese participants were significantly more accurate than the US sample on the SAO and SOQ. The Austrian participants scored significantly higher than the US and the Taiwanese participants. The results of the interviews showed that the Taiwanese experienced teacher participants were more likely to report learning size and scale through in-school experiences than the Austrian or the US participants. US teachers reported learning size and scale most often through participating in hobbies and sports, Taiwanese teachers reported learning scale through sports and reading, and Austrian teachers most often noted that they learned about scale through travel.     

Inquiry-Based Professional Development: What does it take to support teachers in learning about inquiry and nature of science?

This study examined the geologic and evolutionary subject matter and views of inquiry and nature of science (NOS) of a group of 5th–9th grade teachers, and a comparison group, before and after participating in an inquiry-based professional development (PD) experience. Project teachers participated in an intensive, week-long, resident institute where they learned about geology, evolutionary concepts, NOS, and inquiry while engaging in an authentic scientific investigation. They were also given support in how to teach these topics using an inquiry-based approach. Analyses of data indicate that project teachers showed greater gains in subject matter than comparison teachers and the relative change was significantly different statistically. Furthermore, most project teachers demonstrated a shift from less informed to more informed views of inquiry and NOS and the relative change between participant and comparison teachers was significantly different statistically. These gains are promising because they suggest that short-term and intensive PD can support teachers in enhancing their knowledge and views. Moreover, analysis of post-programme questionnaires and interviews indicated that supporting teachers in reflecting on the relationship between their former classroom teaching practice, and new knowledge acquired during PD, may be an important link in enhancing teacher knowledge and supporting change in practice. This suggests that enhanced knowledge and views may not be the only factor contributing to changing one's practice. The study points to the importance of reflection in promoting teacher change. Results from this study add insights to supporting teachers in enacting inquiry-based instruction and teaching about NOS in their classrooms.
