Effect of knowledge integration activities on students' perception of the earth's crust as a cyclic system

Systems thinking is regarded as a high‐order thinking skill required in scientific, technological, and everyday domains. However, little is known about systems thinking in the context of science education. In the current research, students' understanding of the rock cycle system after a learning program was characterized, and the effect of a concluding knowledge integration activity on their systems thinking was studied. Answers to an open‐ended test were interpreted using a systems thinking continuum, ranging from a completely static view of the system to an understanding of the system's cyclic nature. A meaningful improvement in students' views of the rock cycle toward the higher side of the systems thinking continuum was found after the knowledge integration activity. Students became more aware of the dynamic and cyclic nature of the rock cycle, and their ability to construct sequences of processes representing material transformation in relatively large chunks significantly improved. Success of the knowledge integration activity stresses the importance of postknowledge acquisition activities, which engage students in a dual process of differentiation of their knowledge and reintegration in a systems context. We suggest including such activities in curricula involving systems‐based contents, particularly in earth science, in which systems thinking can bring about environmental literacy. © 2003 Wiley Periodicals, Inc.

Learning with multiple representations: Extending multimedia learning beyond the lab

The present study extended multimedia learning principles beyond the lab to an ecologically valid setting (homework). Eighteen information cards were used to perform three homework tasks. The control group students learnt from single representation (SR) cards that presented all information as printed text. The multiple representation (MR) group students received the same information, but each card contained either printed text or an informationally equivalent graphic such as a chart or graph. The MR group students performed better than the SR group students on accuracy of their homework answers and on subsequent posttest retention and transfer, and used more information cards while learning. The improved MR group students' performance is discussed in relation to two alternative possible explanations – the nature of the information sources and students' motivation to learn.     

Strategic Keyboard Training and Spelling Improvement among Children with Learning Disabilities and Mental Retardation

The aim of the study was to investigate the effectiveness of a strategic keyboard training program for improving the spelling performance of children with mild disabilities. The sample consisted of 36 mildly disabled students divided into two groups: 18 learning disabled students, and 18 educable mentally retarded students. The teachers used strategic procedures emphasising awareness of word structure and spelling strategies, combined with keyboard training, for a duration of three months (45‐minute sessions, twice weekly). The results demonstrated a significant decrease in spelling errors, as assessed through computer typing and handwriting. However, the comparisons between the group achievements of the learning disabled and mentally retarded children did not reveal significant differences in the development of the spelling performance. Analysis of the results, and of the four case‐studies, pin‐pointed attention onto the initial individual differences in the spelling performance, and onto the students’ individual learning style during training, emphasising the need for an individualised approach in remedial computerised spelling procedures.     

Interviewing youthful suspects in alleged sex crimes: a descriptive analysis

OBJECTIVE: To introduce and evaluate a structured interview protocol designed for investigative interviews of youthful alleged perpetrators of child sexual abuse. METHOD: Seventy-two alleged perpetrators ranging from 9 to 14 years of age (M = 12 years) were interviewed by 1 of 13 experienced youth investigators, employed by the Israeli Ministry of Labour and Social Affairs, about incidents that had been reported by alleged victims. All interviews were conducted as part of the investigators' regular work and followed the structured interview guide appended to this article. RESULTS: Interviewers questioned older and younger children similarly, but addressed fewer invitations, directive questions, and option-posing prompts to suspects who denied the allegations than to those who partially or fully admitted them. The total number of details provided by the suspects did not vary depending on their age or whether or not they fully or partially admitted the allegations. In both cases, more information was elicited using invitations rather than suggestive or option-posing prompts. CONCLUSION: Contrary to expectations, suspects who at least partially admitted their involvement provided considerable amounts of information and were very responsive to free recall prompts, although interviewers used more risky (potentially error-inducing) prompts when interviewing suspects rather than alleged victims.     

The development of communicative and narrative skills among preschoolers: lessons from forensic interviews about child abuse

This study examined age differences in 299 preschoolers' responses to investigative interviewers' questions exploring the suspected occurrence of child abuse. Analyses focused on the children's tendencies to respond (a) at all, (b) appropriately to the issue raised by the investigator, and (c) informatively, providing previously undisclosed information. Linear developmental trends characterized all types of responding. When the types of prompts were considered, 3- to 4-year-olds responded slightly more informatively to specific (directive) recall prompts than to open-ended prompts whereas children aged 5 and older were more responsive to open-ended recall prompts. The findings suggest that even 3-year-olds can provide information about experienced events when recall processes are activated, although the ability to provide narrative responses to open-ended recall prompts only becomes reliable later in development.     

It Takes a Village: Developing Library of Congress Genre/Form Terms

The Library of Congress (LC) is in the process of developing a separate thesaurus of genre/form terms, which describe what a work or expression is, rather than what it is about. From the beginning, LC policy specialists realized that to accomplish this undertaking, it would be both necessary and desirable to collaborate with the library community. This article examines and evaluates the various methods of collaboration used by LC in the creation of the genre/form thesaurus.     

Science and Scientific Curiosity in Pre-school—The teacher's point of view

Nowadays, early science education is well-accepted by researchers, education professionals and policy makers. Overall, teachers’ attitudes and conceptions toward the science subject domain and science education influence their ways of teaching and engagement. However, there is a lack of research regarding factors that affect this engagement in pre-school years. The main assumption of this study is that teachers’ attitudes regarding science in pre-school can shape children's engagement in science and develop their scientific curiosity. Therefore, the main objectives of this study are to investigate the attitudes of pre-school teachers toward engaging in science and to explore their views about the nature of curiosity: who is a curious child and how can a child's natural curiosity be fostered? An extensive survey was conducted among 146 pre-school teachers by employing both qualitative and quantitative approaches. Results indicate that most of the participants believe that scientific education should begin in early childhood; very young children can investigate and take part in a process of inquiry; and scientific activities in pre-school can influence children's long-term attitudes toward science. Despite these views, most participants felt they did not possess sufficient scientific knowledge. Furthermore, participants expressed diverse opinions when asked to identify what constitutes curiosity, how the curious child can be identified and how a child's curiosity can be fostered. The research findings carry significant implications regarding how to implement scientific activities in pre-school, and how to encourage pre-school teachers to engage children in scientific activities in a way that will nurture their natural curiosity.     

Encouraging Girls into Science and Technology with Feminine Role Model: Does This Work?

This study examines the effect of a program that aimed to encourage girls to choose a science, technology, engineering, and mathematics (STEM) career in Israel. The program involved school visits to a high-tech company and meeting with role model female scientists. Sixty ninth-grade female students from a Jewish modern-orthodox single-sex secondary school in the same city as the company participated in the study. The control group contained 30 girls from the same classes who did not participate in the program. Data were collected through pre-post questionnaires, observations, and focus group interviews. It was analyzed for three main themes: perceptions of scientists and engineers, capability of dealing with STEM, and future career choice. Findings indicated respect toward the women scientists as being smart and creative, but significant negative change on the perceptions of women scientists/engineers, the capability of dealing with STEM, and the STEM career choices. Possible causes for these results are discussed, as well as implications for education.     

Teachers’ interpretations of texts-image juxtapositions in textbooks: From the concrete to the abstract

The paper examined expert literature teachers’ coping with a novel textbook, integrating literature with visual arts, which is a particular interdisciplinary case of text-image relations in textbooks. Examination was performed within the framework of teachers’ responses to curricular changes and of theory regarding strategies of interdisciplinary instruction. Data regarding teachers’ coping was collected via video recorded deep interviews and analysed qualitatively using the phenomenological approach. Findings revealed four phases of a recurring pattern of performance: (a) retrieving prior knowledge about texts, (b) cycles of processing and refinement (comprising comparing-identifying-matching, making meaning of elements in contexts, eliciting themes and deeply examining artworks’ devices), (c) mindful evaluation of the juxtaposition, and (d) pedagogical reasoning. Four potential roles of the textbook visual artworks, for promoting literature learning, were inferred. The study shed some light on the involvement of teacher cognition and culture of teaching in the reading, evaluating, and adapting of novel curricula. A deeper understanding of the factors involved in the introduction of novel materials, examined from a cognitive perspective, may inform teachers’ professional development and curriculum developers as well as promote implementations of curricular reforms.
