The Impact of High School Science Teachers’ Beliefs,Curricular Enactments and Experience on Student Learning During an Inquiry-based Urban Ecology Curriculum

Inquiry-based curricula are an essential tool for reforming science education yet the role of the teacher is often overlooked in terms of the impact of the curriculum on student achievement. Our research focuses on 22 teachers’ use of a year-long high school urban ecology curriculum and how teachers’ self-efficacy, instructional practices, curricular enactments and previous experience impacted student learning. Data sources included teacher belief surveys, teacher enactment surveys, a student multiple-choice assessment focused on defining and identifying science concepts and a student open-ended assessment focused on scientific inquiry. Results from the two hierarchical linear models indicate that there was significant variation between teachers in terms of student achievement. For the multiple-choice assessment, teachers who spent a larger percentage of time on group work and a smaller percentage of time lecturing had greater student learning. For the open-ended assessment, teachers who reported a higher frequency of students engaging in argument and sharing ideas had greater student learning while teachers who adapted the curriculum more had lower student learning. These results suggest the importance of supporting the active role of students in instruction, emphasising argumentation, and considering the types of adaptations teachers make to curriculum.     

Use of First‐hand and Second‐hand Data in Science: Does data type influence classroom conversations?

In this paper, we examine how students discuss and interpret data and whether these actions vary depending on the type of data they analyse. More specifically, we are interested in whether students perform differently when analysing first‐hand data, which they collect themselves, compared with second‐hand data provided to them. Our data analysis focused on two classrooms using two different curriculum units, chemistry in Grade 7 and biology in Grade 8, collected during the 2002/03 school year from a Mid‐western urban middle school in the USA. We analysed classroom videotape associated with lessons in which students discussed first‐hand and second‐hand data both in small group settings and full class discussions. We found the two types of data offer different benefits and limitations, suggesting that both types of data are important for students to work with as they develop skills in scientific inquiry practices. We discuss the characteristics of classroom discussions around different data sources as well as implications for the design of curriculum materials, instructional environments, and student learning in science.     

The commingling of teacher researcher identities: a mediated approach to teaching action research

This article chronicles and discusses a two-semester graduate level action research course in which the co-authors were instructors. Evidence of prospective teachers' appropriation of a ‘teacher researcher’ identity prompted a closer look at the dynamics of the course experience. Using a theoretical foundation based on the work of Vygotsky, Wertsch, Kozulin and Bakhtin, the notions of experiential learning, shared pedagogical mediation, collaborative problem posing and problem solving, and a resultant commingling of teacher and researcher identities are explored

Perceptual organization,phonological awareness,and reading comprehension in adults with and without learning disabilities

It is not clear from research whether, or to what extent, reading comprehension is impaired in adults who have learning disabilities (LD). The influence of perceptual organization (PO) and phonological awareness (PA) on reading comprehension was investigated. PO and PA are cognitive functions that have been examined in previous research for their roles in nonverbal LD and phonological dyslexia, respectively. Nonverbal tests of PO and non-reading tests of PA were administered to a sample of adults with postsecondary education. Approximately two thirds of the sample had previously been diagnosed as having LD. In a multiple regression analysis, tests of PO and PA were used to predict scores for tests of reading comprehension and mechanics. Despite the nonverbal nature of the perceptual organizational test stimuli, PO strongly predicted reading comprehension. Tests of PA predicted decoding and reading speed. Results were interpreted as supporting the hypothesis that integrative processes usually characterized as nonverbal were nonetheless used by readers with and without disabilities to understand text. The study’s findings have implications for understanding the reading of adults with learning disabilities, and the nature of reading comprehension in general.     

Shifting gears: consequences of including two negatively worded items in the middle of a positively worded questionnaire

A questionnaire used in student evaluations of interdisciplinary courses during six semesters contained two Likert items stated in a direct negative mode which were embedded in a questionnaire (14–18 items) in which the remaining items were phrased in a direct positive mode. In the seventh semester and thereafter, the two negative items were restated as direct positive stems. Item‐analysis demonstrated that in the direct negative mode, the two items had low item‐to‐total correlations and that the internal consistency reliability of the sum score could be improved by eliminating the two negatively phrased items. Also, the two negatively worded items defined a separate factor. After they were reworded into a direct positive mode, these two items showed markedly improved item‐to‐total correlations. Moreover, the unique factor disappeared, which suggests that it was a methodological artefact probably attributable to respondent carelessness. Including a few negative items in an otherwise positively stated questionnaire leads to ambiguity of results rather than controlling for response sets. We therefore recommend against the practice.

TRAINING IN SUPPORT OF THE AMERICAN INDIAN ELDERCARE CAMPAIGN: REPLICATION OF AN AMERICAN INDIAN HOME‐CARE TRAINING PROGRAM

In 1991, the federal Administration on Aging initiated the National Eldercare Campaign to broaden the base of commitment and societal involvement to assist today's vulnerable elderly. With Administration on Aging funding, the project described in this study sought to enhance services to American Indian elders by training individuals as home‐care workers. The project replicated a previously developed American Indian paraprofessional home‐care worker curriculum at Fond du Lac Tribal and Community College in Cloquet, Minnesota. This program, which is transferable to Indian and non‐Indian communities, addressed three contemporary aging issues. First, it addressed the need to incorporate diversity and minority aging knowledge into the curriculum of postsecondary education. Second, it provided more accessible and better quality community‐based in‐home care to meet the needs of frail elderly. Third, this training program confronted the pervasive lack of employment opportunities in many American Indian and other minority communities.     

Editorial

As the incoming editorial team we would like to introduce ourselves to our readers. We are looking forward to doing all we can to further the high standard of the journal and its relevance as an international forum for sharing research and scholarship on teaching, learning and curriculum, and the conditions and policy environment of higher education that impinge on academic work. In an effort to ensure that our processes are efficient and transparent, we have revised the Notes to Contributors, which you will find on the back page. Next year the journal goes to four issues which will together form a somewhat larger volume, but will mean that each issue is smaller. The intent is to publish more frequently so that relevance and currency is enhanced. For this reason we will need to put more stress on observing the general rule that papers are to be 5000–7000 words in length. We are also committed to a more rapid turnaround time for submitted papers and have been working to streamline our management systems with the help of our able administrator, Karen Sanecki.     

Development of a Measure to Assess Youth Self-reported Experiences of Activity Settings (SEAS)

There is a need for psychometrically sound measures of youth experiences of community/home leisure activity settings. The 22-item Self-Reported Experiences of Activity Settings (SEAS) captures the following experiences of youth with a Grade 3 level of language comprehension or more: Personal Growth, Psychological Engagement, Social Belonging, Meaningful Interactions, and Choice & Control. Forty-five youth aged 14–23 years (10 with severe disabilities) completed the SEAS in 160 leisure activity settings. The SEAS has good to excellent internal consistency (Cronbach’s alpha from 0.71 to 0.88) and moderate test–retest reliability (mean scale intra-class correlation coefficient = 0.68), as expected due to changes in activity settings over time. The SEAS was able to differentiate various types of activity settings and participation partners. The SEAS can be used to gain greater understanding of situation-specific experiences of youth participating in various types of recreation and leisure activity settings, including youth with different types of disabilities and those without disabilities.
