Australian undergraduate primary school student‐teachers’ responses to child sexual abuse and its mandatory reporting

This study aims to understand how primary school teachers, as mandatory reporters of child sexual abuse, are responding to child sexual abuse and its mandatory reporting, even though many teachers do not receive a compulsory course in Child Protection and its legal requirements in their pre‐service university training. A cohort of 81 Australian final fourth‐year Bachelor of Education (Primary) student‐teachers was asked about four aspects of it. Qualitative data gathered from these student‐teachers’ questionnaires provide important insights into their knowledge of child sexual abuse; their knowledge of Department of Education policy on it; their professional competence in mandatory reporting of it; and their recommended educational and professional training in it. The results show that all of these student‐teachers feel inadequately prepared to address child sexual abuse and mandatory reporting in schools, being unaware of both knowledge of it and the Department’s policy, even though many recognise the gravity of sexual abuse for the child survivor and the need, and seriousness, of child protection. Finally, these student‐teachers all want better training about these issues during their four‐year degree. In conclusion, these results, and some recommendations, may provide a guide for curriculum planners to design compulsory and appropriate pre‐service university courses to enhance student‐teachers’ knowledge, skills and competencies about child sexual abuse and its mandatory reporting.     

Creating Realistic Data Sets with Specified Properties via Simulation

We explain how to simulate both univariate and bivariate raw data sets having specified values for common summary statistics. The first example illustrates how to ‘construct’ a data set having prescribed values for the mean and the standard deviation – for a one‐sample t test with a specified outcome. The second shows how to create a bivariate data set with a specified correlation coefficient.     

Environmental literacy of pre‐service teachers in Israel: a comparison between students at the onset and end of their studies

The adequate preparation of teacher education students in environmental education is a prerequisite for their future ability to design and implement effective environmental education. This longitudinal study compared the environmental literacy of 214 students at the onset and towards the end of their studies, in three academic colleges of education in Israel. A questionnaire and a paired pre‐test–post‐test design were used to explore environmental literacy variables and their perceptions regarding the contribution of their college studies to their environmental literacy and worldviews. Students towards the end of their studies reported increased involvement in most of the study’s environmental behaviour categories as compared to the beginning. Despite this, the pattern characterizing their environmental behaviour did not change: a negative relationship was found between the frequency at which they engaged in different behaviour categories and the environmental‐commitment‐level of the corresponding category. Overall, while their environmental attitudes were positive, both as beginning and advanced students, their level of environmental knowledge remained low. Advanced students noted the limited contribution of their studies to the development of their environmental literacy and worldviews. In spite of the improvement in students’ environmental literacy over the course of their studies, the levels of their environmental literacy towards the end of studies are still inadequate for educators. The findings from this study are of relevance to decision makers bringing environmental education into the policy of teacher education institutions, and for program developers, on effective directions for integrating environmental education given the structures and frameworks of current programs.     

A new microelectronics curriculum created by Synopsys, Inc.

Rapid changes in integrated circuits （IC） technology and constantly shrinking process geometries demand a new curriculum that meets the contemporary requirements for IC design. This is especially important for 90nm and below technologies and the use of state-of-the-art EDA design tools and advanced IC design techniques. The creation of new curriculum is laborious and requires a combination of effort from many specialists from different countries to obtain the best quality. This paper describes the experience in developing a new microelectronics curriculum, based on using Synopsys EDA tools, that is successfully deployed in leading technical universities around the world.     

Computer technology and complex problem solving: Issues in the study of complex cognitive activity

Goals and plans organize much of complex problem solving behavior and are often inferable from action sequences. This paper addresses the strengths and limitations of inferring goals and plans from information that can be derived from computer traces of software used to solve mathematics problems. We examined mathematics problem solving activity about distance, rate, time relationships in a computer software environment designed to support understanding of functional relationships among these variables (e.g., distance =rate × time; time=distance/rate) using graphical representations of the results of simulations. Ten adolescent-aged students used the software to solve two distance, rate, time problems, and provided think-aloud protocols. To determine the inferability of understanding from the action traces, coders analyzed students' understanding from the computer traces alone (Trace-only raters) and compared these to analyses based on the traces plus the verbal protocols (Traceplus raters). Inferability of understanding from the action traces was related to level of student understanding how they used the graphing tool. When students had a good understanding of distance, rate, time relationships, it could be accurately inferred from the computer traces if they used the simulation tool in conjunction with the graphing tool. When students had a weak understanding, the verbal protocols were necessary to make accurate inferences about what was and was not understood. The computer trace also failed to capture dynamic exploration of the visual environment so students who relied on the graphing tool were inaccurately characterized by the Trace-only coders. Discussion concerns types of scaffolds that would be helpful learning environment for complex problems, the kind of information that is needed to adequately track student understanding in this content domain, and instructional models for integrating learning environments like these into classrooms.Members of the Cognition and Technology Group at Vanderbilt who have contributed to this project are (in alphabetical order) Helen Bateman, John Bransford, Thaddeus Crews, Allison Moore, Mitchell Nathan, and Stephen Owens.

A comparison of WISC-R and WAIS-R IQS in a mentally retarded residential population

Although typically regarded as equivalent instruments, the WISC-R and the WAIS-R yield significantly different Verbal, Performance, and Full Scale IQs for an intellectually subaverage group, with the WAIS-R consistently providing higher scores. Implications of this “built-in” increment for issues of eligibility for educational placements and societal benefits are serious, and careful interpretation of IQs in the context of other relevant data is necessary.
