Huber Inventory of Trainee Self‐efficacy: Assessment of measurement models

The purpose of this study was to further examine the factor structure of the Huber Inventory of Trainee Self‐Efficacy (HITS), a measure of school psychology trainee self‐efficacy. Lockwood et al. (2017, Psychol. Sch., Vol. 54, pp. 655–670) extant data set, collected from 520 school psychology trainees, was utilized. Four measurement models were examined for model fit and factor loadings. Of the four models, a bifactor model with a single latent general self‐efficacy (GSE) and latent domain‐specific factors (i.e., Multidimensional Assessment Skills, Counseling Skills, Professional Interpersonal Skills, and Research Skills) was the most parsimonious. However, standardized loadings indicated that all practice‐related items loaded more significantly onto GSE than their domain‐specific factors, indicating the utility of GSE for practice‐related skills. Of note, the Research Skills factor displayed greater domain‐specific loadings than general loadings. These findings suggest that GSE may be the best indicator of trainee self‐efficacy, though a two‐factor model that represents practical skills versus research skills may also be appropriate. Additionally, reliability scores indicate that subscale interpretation may also be reasonable. Limitations, implications for trainers of school psychologists, and for future research directions are discussed.     

The use of engineering design scenarios to assess student knowledge of global,societal, economic,and environmental contexts

Product archaeology as an educational approach asks engineering students to consider and explore the broader societal and global impacts of a product's manufacturing, distribution, use, and disposal on people, economics, and the environment. This study examined the impact of product archaeology in a project-based engineering design course on student attitudes and perceptions about engineering and abilities to extend and refine knowledge about broader contexts. Two design scenarios were created: one related to dental hygiene and one related to vaccination delivery. Design scenarios were used to (1) assess knowledge of broader contexts, and (2) test variability of student responses across different contextual situations. Results from pre- to post-surveying revealed improved student perceptions of knowledge of broader contexts. Significant differences were observed between the two design scenarios. The findings support the assumption that different design scenarios elicit consideration of different contexts and design scenarios can be constructed to target specific contextual considerations.     

Opportunities Lost: The Pendulum in the USA National Science Education Standards

This article is based on my recent book Time for Science Education (Plenum Publishers, 1998). It begins with the treatment afforded the pendulum in the US National Science Education Standards, and a number of other contemporary curriculum documents. It notes that all of these documents advocate liberal, or wide, goals for science education, including students understanding something of the historical and cultural significance of science. It notes that all the documents ignore the very significant role played by the pendulum in the foundation of modern science, in solving the longitude problem, and in enabling the first accurate clocks to be constructed. There are thus lost opportunities for realising the laudable goals that the Standards set for US science education. Finally, it is claimed that realising these cultural goals for science education requires that the history and philosophy of science be more routinely incorporated into preservice and inservice courses for science teachers.

Bounds for characteristic exponents of discrete linear time varying systems

In this paper we introduce certain constants that characterize exponential stability or exponential unstability of discrete linear time varying systems. We also present bounds for Lyapunov and Perron exponents in terms of the introduced constants.     

Adjustment outcomes of developmental placement: A longitudinal study

Over the years, educators and psychologists have recommended delaying school entry and have developed alternative interventions for young children identified as unready for school. These developmental placement interventions, including readiness kindergartens and pre‐first classes, were developed to avoid both academic and social‐emotional problems in schools. However, the efficacy of these programs has not been proven. This study examined school adjustment outcomes and emotional and learning difficulties, both short‐term and longitudinally, for students who participated in readiness kindergartens and pre‐first classes, as well as for control groups of students. Significant differences were noted in retention rates, dropout rates, and special education placement rates. © 1999 John Wiley & Sons, Inc.     

What types of functions may be the lower Bohl function of a diagonal discrete linear time-varying systems?

In this paper, we give the necessary and sufficient conditions for a function f to be a lower Bohl function of a diagonal discrete linear time-varying systems.     

Using the Principles of BIO2010 to Develop an Introductory,Interdisciplinary Course for Biology Students

Modern biological sciences require practitioners to have increasing levels of knowledge, competence, and skills in mathematics and programming. A recent review of the science curriculum at the University of Queensland, a large, research-intensive institution in Australia, resulted in the development of a more quantitatively rigorous undergraduate program. Inspired by the National Research Council''s BIO2010 report, a new interdisciplinary first-year course (SCIE1000) was created, incorporating mathematics and computer programming in the context of modern science. In this study, the perceptions of biological science students enrolled in SCIE1000 in 2008 and 2009 are measured. Analysis indicates that, as a result of taking SCIE1000, biological science students gained a positive appreciation of the importance of mathematics in their discipline. However, the data revealed that SCIE1000 did not contribute positively to gains in appreciation for computing and only slightly influenced students'' motivation to enroll in upper-level quantitative-based courses. Further comparisons between 2008 and 2009 demonstrated the positive effect of using genuine, real-world contexts to enhance student perceptions toward the relevance of mathematics. The results support the recommendation from BIO2010 that mathematics should be introduced to biology students in first-year courses using real-world examples, while challenging the benefits of introducing programming in first-year courses.
