Mapping undergraduate chemistry students' epistemic ideas about models and modeling

Developing and using scientific models is an important scientific practice for science students. Undergraduate chemistry curricula are often centered on established disciplinary models, and assessments typically provide students with opportunities to use these models to predict and explain chemical phenomena. However, traditional curricula generally provide few opportunities for students to consider the epistemic nature of models and the process of modeling. To gain a sense of how introductory chemistry students understand model changeability, model multiplicity, the evaluation of models, and the process of modeling, we use a construct-mapping approach to characterize the sophistication of students' epistemic knowledge of models and modeling. We present a set of four related construct maps that we developed based on the work of other scholars and empirically validated in an undergraduate introductory chemistry setting. We use the construct maps to identify themes in students' responses to an open-ended survey instrument, the models in chemistry survey, and discuss the implications for teaching.     

Preschool attendance and kindergarten readiness

Scores on the Georgia Kindergarten Assessment Program (GKAP) of 171 students (81 students who had attended preschool and 90 students who had not attended preschool) were analyzed to determine whether school readiness test performance was influenced by participation in preschool programs. Students who had attended preschool demonstrated statistically higher overall school readiness, higher Physical scores, and higher Personal scores than students who did not attend preschool. No difference, however, was found in GKAP scores as a function of type of preschool attended. Only one gender difference was revealed, that in the Social measure on the GKAP in which girls outperformed boys. Implications of our findings and suggestions for further research are discussed.     

Leadership, Learning and Systemic Reform

For three consecutive years, opinion polls in the US have placed education as the top national issue (USA Today, 1999). `Education, Education, Education' has been the personal mantra of UK Prime Minister Tony Blair. These responses are not unique, governments across the globe are engaged in the education reform business, motivated by a range of concerns. Drawing on the experience of a number of countries, this article explores the context for education reform, offering insights into the reform process and questioning some of the conventional orthodoxies about the nature of education change. The author argues that the structural reforms which have been the pre-occupation of governments over recent years have been limited in their impact because of their lack of connection to learning – teacher learning and student learning – and because of the ways in which policy-makers have embarked on the change voyage. She argues that governments need to move away from a compliance models of educational reform, towards an approach which reflects the aspirations of schools and communities, and which is supported by forms of leadership connected to learning.     

Urban African‐American middle school science students: Does standards‐based teaching make a difference?

The current reform movement in science education promotes standards‐based teaching, including the use of inquiry, problem solving, and open‐ended questioning, to improve student achievement. This study examines the influence of standards‐based teaching practices on the achievement of urban, African‐American, middle school science students. Science classes of teachers who had participated in the professional development (n = 8) of Ohio's statewide systemic initiative (SSI) were matched with classes of teachers (n = 10) who had not participated. Data were gathered using group‐administered questionnaires and achievement tests that were specifically designed for Ohio's SSI. Analyses indicate that teachers who frequently used standards‐based teaching practices positively influenced urban, African‐American students' science achievement and attitudes, especially for boys. Additionally, teachers' involvement in the SSI's professional development was positively related to the reported use of standards‐based teaching practices in the classroom. The findings support the efficacy of high‐quality professional development to change teaching practices and to enhance student learning. © 2000 John Wiley & Sons, Inc.

Erase the lines of demarcation: The counselor,the psychologist,and the assessment process

What was once desirable is now mandatory—teamwork between the psychologist and counselor. Because the fundamental function of either profession is basically the same, delineation of job responsibilities may become difficult. Suggestions are offered to reduce the incidence of this problem by reshaping at the training program level. Guidelines also are provided to enhance the working relationship between the psychologist and counselor.     

A comparison of the Stanford-Binet Intelligence Scale and the McCarthy Scales of Children's Abilities with preschool children

The purpose of the present study was to determine the degree to which performance on the McCarthy Scaies of Children's Abilities correlated with performance on the Stanford-Binet for a group of preschoolers. The sample consisted of 44 children ranging in age from 3–11 to 5–4. It was found that the General Cognitive Index scores of the McCarthy Scales correlated well with the Stanford-Binet IQ scores, r^xy = .90. However, 40 of the 44 subjects scored higher on the Stanford-Binet than on the McCarthy Scales.

Correlating Spatial Ability With Anatomy Assessment Performance: A Meta-Analysis

Interest in spatial ability has grown over the past few decades following the emergence of correlational evidence associating spatial aptitude with educational performance in the fields of science, technology, engineering, and mathematics. The research field at large and the anatomy education literature on this topic are mixed. In an attempt to generate consensus, a meta-analysis was performed to objectively summarize the effects of spatial ability on anatomy assessment performance across multiple studies and populations. Relevant studies published within the past 50 years (1969–2019) were retrieved from eight databases. Study eligibility screening was followed by a full-text review and data extraction. Use of the Mental Rotations Test (MRT) was required for study inclusion. Out of 2,450 screened records, 15 studies were meta-analyzed. Seventy-three percent of studies (11 of 15) were from the United States and Canada, and the majority (9 of 15) studied professional students. Across 15 studies and 1,245 participants, spatial ability was weakly associated with anatomy performance (r_pooled = 0.240; CI at 95% = 0.09, 0.38; P = 0.002). Performance on spatial and relationship-based assessments (i.e., practical assessments and drawing tasks) was correlated with spatial ability, while performance on assessments utilizing non-spatial multiple-choice items was not correlated with spatial ability. A significant sex difference was also observed, wherein males outperformed females on spatial ability tasks. Given the role of spatial reasoning in learning anatomy, educators are encouraged to consider curriculum delivery modifications and a comprehensive assessment strategy so as not to disadvantage individuals with low spatial ability.
