Using critical incident reflections: a self-study as a mathematics teacher educator

In this paper, I report the results of a 4-year study into how my students learn to become mathematics teachers during the combined 15-week methods and field placement course I teach. At the start of most weekly methods class meetings, groups of three or four students reported their critical incidents to each other, and then chose one incident to report to the whole class. Each student then submitted a written report of 10 critical incidents for grading. At the end of each semester, I administered a questionnaire about the usefulness of each of the elements of the course. Using these two main data sources, along with my own personal reflections on the course, this paper answers the question “What are the critical incidents preservice teachers encounter during their field experience, and what do they learn about teaching for understanding through reflecting on those critical incidents?” My analysis of the students’ incident reports found that the issues raised focused on four main areas: teaching and classroom management; student factors such as pre-requisite knowledge, understanding, resistance and motivation; issues concerning relationships with colleagues, students and parents; and school organizational issues such as policies and access to resources. Their learning about teaching for understanding focused on three broad areas: the conditions necessary to teach for understanding; facilitators of teaching for understanding; and barriers to teaching for understanding. The paper concludes with a discussion of the lessons learned about fostering reflection in novice teachers, and suggestions for further research.     

Assessing the impact of information services in a regionalized health-care organization

Objectives: Assessment of the usage of medical library services before and after the implementation of several new services, as well as assessment of the clinical impact of the information provided by the medical library. Methods: A sample of employees, residents and physicians were surveyed using a stratified, random selection process in two surveys 4 years apart. The response rate for the first survey was 52% and the response rate for the second survey was 35.2%. Results: Differences in usage included increased overall use of the librarians and library services, decreased use of the Internet as a source of information, and direct and indirect impacts upon patient care. Information needs of respondents also increased to where 65% of employees and 94% of physicians require information at least once a week. Patient management was the main reason for needing information. The top two specific uses were to find out about a condition and determine a treatment plan. Conclusions: These findings parallel some of the findings of other researchers, and contradict the findings of others. Possible explanations for these findings and implications for future research are discussed.     

Measuring the value and impact of health library and information services: past reflections, future possibilities

Objectives: To summarize the context, history and results of research studies conducted on the value and impact of health library and information services by the author since 1975 and to use this as a basis for examining ongoing developments related to evaluation research. To provide a comprehensive bibliography of library value and impact studies. Methods: Literature review and background based on personal involvement in the studies under discussion. Results: The author's studies demonstrate an ongoing evolution of value and impact studies since the mid‐1970s. In health sciences libraries, the approach taken to measuring value and impact has been strongly influenced by the type of research being conducted in the health sciences field as a whole. As a result, health sciences library researchers have become early adopters of methods that incorporate outcome and impact measures and rigorous research designs, and the concept of evidence‐based library and information practice. The paper recommends that a range of research approaches from various disciplines be used to guide future evaluation research. Conclusions: Value and impact studies will continue to be important resources for evidence‐based practice as health information professionals deal with evolving user needs and new ways of delivering information to a variety of audiences.     

Learning to solve addition and subtraction word problems in English as an imported language

This paper reports an intervention phase of a design study aimed to assist second-grade Filipino children in solving addition word problems in English, a language they primarily encounter only in school. With Filipino as the medium of instruction, an out-of-school pedagogical intervention providing linguistic and representational scaffolds was implemented with 17 children. Pre-intervention, children experienced linguistic difficulties and were limited to conceptualising and solving simple additive structures. Post-intervention interviews revealed improved performance and understanding of more complex structures, but only when linguistic difficulties were minimised. The study identified socially and culturally driven barriers to learning: superficial strategies, children’s engagement, and learning in an urban poor context.     

Radial and tibial bone indices in athletes participating in different endurance sports: a pQCT study†

Low magnitude bone-loading sports may benefit bone structure and strength in the exercised limbs. This study compared peripheral quantitative computed tomography measures of radial and tibial diaphyseal strength (strength–strain index, SSI), structure (total area (ToA) and cortical area (CoA), density (CoD) and thickness (CT), and circumferences), muscle cross-sectional area (MCSA) and strength (one-repetition maximum, 1-RM) in male endurance athletes taking part in (i) non-weight-bearing and non-impact sports: swimmers (SWIM, n?=?13) and road cyclists (RC, n?=?10), (ii) non-weight-bearing, impact sport: mountain bikers (MB, n?=?10), (iii) weight bearing and impact sport: runners (RUN, n?=?9). All athlete groups were also compared to sedentary controls (CON, n?=?10). Arm MCSA, 1-RM and radial bone size and strength tended to be greater in SWIM than CON and/or RC (ToA, %difference ±?95%CI, SWIM-CON: 14.6%?±?12.7%; SWIM-RC: 12.9%?±?10.7%) but not different to MB and RUN. RUN had bigger tibial CoA than CON, SWIM and RC (CoA, RUN-CON: 12.1%?±?10.7%; RUN-SWIM: 10.9%?±?9.4%; RUN-RC: 15.8%?±?9.5%) without marked changes in tibial strength indices, lower-limb MCSA or 1-RM. Both MB and RC failed to display any difference in tibial indices, lower-limb MCSA and 1-RM compared to CON. In swimmers, the bone structure and strength of the primary exercised limbs, the arms, is greater than controls and road cyclists. Conversely, although runners experience impact and weight-bearing loading, tibial structure is greater without a substantial difference in tibial strength compared to controls and non-impact sports. Failure to observe a difference in tibial indices in MB and RC compared to controls is unexpected.     

A comparative analysis of the Bender-Gestalt and beery/buktenica tests of visual-motor integration as a function of grade level for regular education students

One hundred twenty-five randomly selected regular education students in grades kindergarten through three were administered the Bender-Gestalt and Beery/Buktenica tests of visual-motor integration. Significant differences between the mean Bender and Beery age equivalent scores at each grade level were found. Correlation coefficients ranged from.21 at the kindergarten level to.71 for the total group and were significant at the first and second grade, as well as for the total group. Implications for their utilization in assessing fine motor readiness development, particularly as they apply to the identification of learning disabilities, are discussed.     

Awareness of the structure and meaning of morphologically complex words: Impact on reading

Many new words middle school children encounter in books they read are relatively transparent derived forms whose meanings might be figured out through analysis of the word parts. Of importance is whether students can not only read and recognize the structure of morphologically complex words but also determine their meanings. This issue was addressed by investigating the relationship of third and fifth graders' awareness of the structure and meanings of derived words and the relationship of these forms of morphological awareness to word reading and reading comprehension. The results showed that awareness of structure was significantly related to the ability to define morphologically complex words; some aspects were also significantly related to the reading of derived words. The three morphology tasks accounted for significant variance in reading comprehension at both grade levels, but the contribution was stronger for the fifth than the third grade. It may be educationally noteworthy that morphological analysis contributed significantly to reading comprehension for the third graders because they are presumably just beginning to learn to read and understand morphologically complex words.     

Job Stress and Satisfaction Among Special Education Teachers: Effects of gender and social role orientation

Eighty-nine female and 43 male special education teachers completed a battery of instruments dealing with job stress and satisfaction and social role characteristics. Social role orientation (expressive, instrumental, balanced, and undifferentiated) was determined for each of the teachers both on- and off-the-job using the Bem Sex Role Inventory, and then analysed in relation to six indices of work-related stress and satisfaction. For female special educators, a balanced social role orientation was associated with higher levels of satisfaction and lower levels of stress, while an undifferentiated orientation was associated with lower levels of satisfaction and higher levels of stress. Implications for teacher preparation programs are discussed, and suggestions for future research are included.     

The Integration of Preservice Teachers’ Naive and Informed Beliefs about Learning and Teaching

Preservice teacher education students are likely to have acquired naive beliefs about learning and teaching, that need to be integrated with theoretically informed beliefs, if they are to function effectively in classrooms. This study explored the nature of such integration using a sample of Graduate Diploma in Education students engaged in an educational psychology subject which was designed to help students develop constructivist beliefs and approaches to learning. Investigation of students’ journal entries, written statements, and stimulated recall interviews related to videotaped practice teaching sessions, revealed that students were able to integrate prior beliefs with the theoretical content of the course, enabling them to describe, and in some cases, evidence informed conditional knowledge.
