Evolution as a controversial issue: a review of instructional approaches

Although evolution has long been considered a controversial issue, little effort has been made to ensure that instructional approaches address the controversial nature of the issue. A framework for understanding the nature of controversy and some defining characteristics of controversial issues are provided. In light of this framework evolution is evaluated to address the defining characteristics of the issue that make it controversial. The purpose of this exploratory review of evolution instruction is to identify a range of instructional approaches reported in extant literature and to determine the extent to which each approach is commensurate with teaching evolution as a controversial issue.     

Fostering alphabet knowledge development: a comparison of two instructional approaches

Preschool-aged children (n = 58) were randomly assigned to receive small group instruction in letter names and/or sounds or numbers (treated control). Alphabet instruction followed one of two approaches currently utilized in early childhood classrooms: combined letter name and sound instruction or letter sound only instruction. Thirty-four 15 minute lessons were provided, with children pre- and post-tested on alphabet, phonological awareness, letter–word identification, emergent reading, and developmental spelling measures. Results suggest benefits of combined letter name and sound instruction in promoting children’s letter sound acquisition. Benefits did not generalize to other emergent literacy skills.     

Implementation of instructional innovations in K-8 science classes: perspectives of inservice teachers

The Iowa Chautauqua Programme (ICP) was disseminated through the National Diffusion Network (NDN) of the US Department of Education as an exemplary model of professional development for inservice science teachers. As a result, several new professional development programmes, emulating the Iowa Chautauqua model, were initiated in diverse settings across the USA. Adhering closely to the principal features of the ICP, the Collier Chautauqua Programme (CCP) was developed in Collier County, Florida. Teacher concerns associated with classroom implementation of instructional innovations promoted by the programme were studied qualitatively during the first year of programme implementation. Data were collected through individual and focus group interviews, workshop and classroom observations, and pre-formatted teacher journals. These data were analysed using the stages of concern (SoC) of the concerns based adoption model (CBAM) as the conceptual framework. Results reveal intricate relationships between classroom implementation by teachers and programme implementation by the school district.     

The development of a science process assessment for fourth-grade students

In this study, a multiple-choice test entitled the Science Process Assessment was developed to measure the science process skills of students in grade four. Based on the Recommended Science Competency Continuum for Grades K to 6 for Pennsylvania Schools, this instrument measured the skills of (1) observing, (2) classifying, (3) inferring, (4) predicting, (5) measuring, (6) communicating, (7) using space/time relations, (8) defining operationally, (9) formulating hypotheses, (10) experimenting, (11) recognizing variables, (12) interpreting data, and (13) formulating models. To prepare the instrument, classroom teachers and science educators were invited to participate in two science education workshops designed to develop an item bank of test questions applicable to measuring process skill learning. Participants formed “writing teams” and generated 65 test items representing the 13 process skills. After a comprehensive group critique of each item, 61 items were identified for inclusion into the Science Process Assessment item bank. To establish content validity, the item bank was submitted to a select panel of science educators for the purpose of judging item acceptability. This analysis yielded 55 acceptable test items and produced the Science Process Assessment, Pilot 1. Pilot 1 was administered to 184 fourth-grade students. Students were given a copy of the test booklet; teachers read each test aloud to the students. Upon completion of this first administration, data from the item analysis yielded a reliability coefficient of 0.73. Subsequently, 40 test items were identified for the Science Process Assessment, Pilot 2. Using the test-retest method, the Science Process Assessment, Pilot 2 (Test 1 and Test 2) was administered to 113 fourth-grade students. Reliability coefficients of 0.80 and 0.82, respectively, were ascertained. The correlation between Test 1 and Test 2 was 0.77. The results of this study indicate that (1) the Science Process Assessment, Pilot 2, is a valid and reliable instrument applicable to measuring the science process skills of students in grade four, (2) using educational workshops as a means of developing item banks of test questions is viable and productive in the test development process, and (3) involving classroom teachers and science educators in the test development process is educationally efficient and effective.     

Computer-based tools for instructional design: An introduction to the special issue

Modern instructional theories are characterized by their focus on rich, multidisciplinary and often collaborative learning tasks that are somehow representative for authentic, real life tasks. This new view on learning heavily increases the complexity of the design process and the resulting instructional systems. It is argued that computer-based instructional design (ID) tools may help to deal with this growing complexity. A framework to distinguish different kinds of ID tools is presented. This framework is then used to introduce the contributions to this special issue.     

The impact of instructional practices in Grades 1 and 2 on reading and spelling achievement in high poverty schools

The objective of this investigation was to examine how instructional practices in 107 first- and second-grade classrooms in 17 high poverty schools moderate the impact on literacy outcomes of literacy-related skills students bring to the classroom. Ratings of teaching effectiveness and time allocation to literacy activities were obtained. Twenty time allocation variables were reduced into seven patterns of literacy activities that were examined as predictors of reading and spelling outcomes. Students’ initial reading ability and interactions of teaching effectiveness ratings by time allocation components predicted reading and spelling outcomes. Discussion centers on immutable versus flexible views of reading development and analytic approaches to examining instructional practices.     

The mainstreaming of charities into schools

Abstract

This paper focuses on the ‘mainstreaming’ of charities into schools. There have been growing concerns about the permeation of business and business values in education, but relatively little attention has been paid to the ways in which schools are increasingly engaged in the ‘business’ of fundraising for charities. Drawing on survey data from the WISERDEducation Multi-Cohort Study (WMCS), the paper outlines young people’s relationship with charities. The data show that young people have a high degree of engagement with charities, in which schools play a significant part. There are likely to be many positive aspects to this engagement, inasmuch as it fosters and reflects young people’s sense of collective responsibility. However, there are also issues about the extent to which this high level of involvement marginalises other approaches to promote the social good and increases the permeation of business values and business into school. The paper concludes that the current mainstreaming of charities into schools is not necessarily a self-evident ‘good’ and that this under-researched phenomenon deserves greater critical attention within and outwith schools.

The instructional design portfolio:

Conclusion In order to make PIHnet forum more usable and useful, we recently redesigned the forum tool based on findings from a survey, interviews and observations of user posting patterns. We also developed a journal tool to assist teachers with their personal reflection. Interviews with four users showed that the new forum was easy to use and effectively helped them communicate with other members. We are still developing the journal tool, so user experiences with the new journal tool have not been investigated yet. We will continue to improve the tools based on critical feedback from actual users.

Identifying and predicting classes of response to explicit phonological spelling instruction during independent composing

After explicit spelling instruction, low achieving second grade spellers increased the number of correctly spelled words during composing but differed in response trajectories. Class 1 (low initial and slow growth) had the lowest initial performance and improved at a relatively slow rate. Class 2 (high initial and fast growth) started higher than Class 1 but below Class 3 and improved at the fastest rate. Class 3 (highest initial but slow growth) had the highest initial performance but improved at a rate similar to Class 1. Class 3 differed from Classes 1 and 2 on orthographic coding. Classes 1, 2, and 3 differed on rapid automatic naming (RAN letters). Spelling instruction plus supplementary activities to improve orthographic coding in working memory and rapid, automatic coordination of phonological and orthographic codes may facilitate transfer of spelling learned during instruction to applying that spelling knowledge during independent composing.
