To What Extent Do Reform-prepared Upper Elementary and Middle School Science Teachers Maintain Their Beliefs and Intended Instructional Actions as they are Inducted into Schools?

We report the results of survey research that collected responses of an identical sample (31 beginning mathematics and science teachers, elementary and middle school level) that graduated from a reform-based mathematics and science teacher preparation program, the Maryland Collaborative for Teacher Preparation (MCTP). We compared responses of the same beginning teachers over the two administrations of the survey. The 1st administration was conducted soon after the beginning teachers graduated from the MCTP program, but had not started full teaching. The 2nd administration was conducted after the new teachers had taught full time for a minimum of a full year, with the majority having taught for 2 years. Results indicated that in all areas the MCTP teachers maintained their reform-based beliefs.     

The relative contributions of the Cattell‐Horn‐Carroll cognitive abilities in explaining writing achievement during childhood and adolescence

This study examined the relative contributions of measures of Cattell‐Horn‐Carroll (CHC) cognitive abilities in explaining writing achievement. Drawing from samples that covered the age range of 7 to 18 years, simultaneous multiple regression was used to regress scores from the Woodcock‐Johnson III (WJ III; Woodcock, McGrew, & Mather, 2001) that represent CHC broad and narrow abilities onto the WJ III Basic Writing Skills and Written Expression cluster scores. At most age levels, Comprehension‐Knowledge demonstrated moderate to strong effects on both writing clusters, Processing Speed demonstrated moderate effects on Basic Writing Skills and moderate to strong effects on Written Expression, and Short‐Term Memory demonstrated moderate effects. At the youngest age levels, Long‐Term Retrieval demonstrated moderate to strong effects on Basic Writing Skills and moderate effects on Written Expression. Auditory Processing, and Phonemic Awareness demonstrated moderate effects on only Written Expression at the youngest age levels and at some of the oldest age levels. Fluid Reasoning demonstrated moderate effects on both writing clusters only during some of the oldest age levels. Visual‐Spatial Thinking primarily demonstrated negligible effects. The results provide insights into the cognitive abilities most important for understanding the writing skills of children during the school‐age years. © 2008 Wiley Periodicals, Inc.     

Adding an expert to the team: The expert flight plan critic*

This paper reports the development of a practical tool that provides expert feedback to students following an extended simulation exercise in cross‐country flight planning. In contrast to development for laboratory settings, the development of an expert instructional product for everyday use posed some interesting challenges, including dealing with a larger content scope, less ideal and controllable content structure, greater emphasis on the completeness and continuity of the student experience, and more stringent limits on time and money. Moreover, the transition from laboratory to real world caused the developers to think more critically of the principles of instruction embodied in the product and to place less emphasis on computer tool and technique questions. The product, which will be used in the context of routine ab initio pilot training, is described in terms of how these problems were solved and what lessons were learned that can be applied to the development of future instructional systems involving expertise.     

Learning in context: Technology integration in a teacher preparation program informed by situated learning theory

This investigation explores the effectiveness of a teacher preparation program aligned with situated learning theory on preservice science teachers' use of technology during their student teaching experiences. Participants included 26 preservice science teachers enrolled in a 2‐year Master of Teaching program. A specific program goal was to prepare teachers to use technology to support reform‐based science instruction. To this end, the program integrated technology instruction across five courses and situated this instruction within the context of learning and teaching science. A variety of data sources were used to characterize the participants' intentions and instructional practices, including classroom observations, lesson plans, interviews, and written reflections. Data analysis followed a constant comparative process with the goal of describing if, how, and why the participants integrated technology into their instruction and the extent to which they applied, adapted, and innovated upon what they learned in the science teacher preparation program. Results indicate that all participants used technology throughout their student teaching for reform‐based science instruction. Additionally, they used digital images, videos, animations, and simulations to teach process skills, support inquiry instruction, and to enhance student engagement in ways that represented application, adaptation, and innovation upon what they learned in the science teaching methods program. Participants cited several features of the science teacher preparation program that helped them to effectively integrate technology into their instruction. These included participating in science lessons in which technology was modeled in the context of specific instructional approaches, collaborating with peers, and opportunities for feedback and reflection after teaching lessons. The findings of this study suggest that situated learning theory may provide an effective structure for preparing preservice teachers to integrate technology in ways that support reform‐based instruction. © 2013 Wiley Periodicals, Inc.

Evaluating an Automatically Scorable, Open-Ended Response Type for Measuring Mathematical Reasoning in Computer-Adaptive Tests

The first generation of computer-based tests depends largely on multiple-choice items and constructed-response questions that can be scored through literal matches with a key. This study evaluated scoring accuracy and item functioning for an open-ended response type where correct answers, posed as mathematical expressions, can take many different surface forms. Items were administered to 1,864 participants in field trials of a new admissions test for quantitatively oriented graduate programs. Results showed automatic scoring to approximate the accuracy of multiple-choice scanning, with all processing errors stemming from examinees improperly entering responses. In addition, the items functioned similarly in difficulty, item-total relations, and male-female performance differences to other response types being considered for the measure.     

Equivalence of Free-Response and Multiple-Choice Items

This study examined the relationship of multiple-choice and free-response items contained on the College Board's Advanced Placement Computer Science (APCS) examination. Confirmatory factor analysis was used to test the fit of a two-factor model where each item format marked its own factor. Results showed a single-factor solution to provide the most parsimonious fit in each of two random-half samples. This finding might be accounted for by several mechanisms, including overlap in the specific processes assessed by the multiple-choice and free-response items and the limited opportunity for skill differentiation afforded by the year-long APCS course.

Teaching elementary science methods to women: A male professor's experience from two perspectives

This is an action research study using an N of one (a case study) from the theoretical stance of symbolic interaction. This study of one male science education professor's experience teaching elementary science methods to females is told from two perspectives: the perspective of the professor and of a female coresearcher. In this study, the coresearchers present their perspectives of studying the gender difference between the male professor and his female elementary science method students and the attempts he makes to implement gender inclusive pedagogy. Discussion focuses on what each has learned through this study of examining the professor's practice as he takes action to improve the teaching and learning in his science method classes predominately populated by women. A key implication from this study is the assertion that male science methods professors have a special obligation to break the cycle of inequity in science teaching and learning for females by taking action to foster a female-friendly classroom climate and to encourage females to become engaged in class conversations and activities. However, professors should be aware that both female and male elementary teachers socialized in a system privileging men may not value efforts, or may even actively resist efforts to promote gender-inclusive science education during science methods. © 1998 John Wiley & Sons, Inc.
