Police officers' perceptions and experiences of promoting honesty in child victims and witnesses

AbstractPurposeThis two‐phase study employed a mixed‐methods design to explore UK police officers' perceptions and experiences of promoting honesty in child witnesses with a special focus on the recommended inclusion of Truth‐Lies Discussions (TLDs) at the start of interviews with children.MethodIn Phase 1, police officers completed an online survey designed to cover their experiences and perceptions regarding truth‐promotion with child witnesses. In Phase 2, police officers were individually interviewed to elicit an in‐depth understanding of current practice relating to this aspect of investigative interviews with children.ResultsAround half of the survey respondents believed that TLDs promote honesty in children. The majority reported always using TLDs during interviews to ensure compliance with UK best‐practice guidance. There was evidence of a misconception among some police officers that children's performance on TLDs was related to their subsequent truth‐telling behaviour. Following analysis of the interview transcripts, we found a main theme of police officers' uses of TLDs, which included (i) gauging children's conceptual understanding of truths/lies, (ii) ensuring no deviation from guidance and (iii) communicating children's credibility to the court. A second main theme revealed the challenges and obstacles police officers perceived when embarking on TLDs. These were that (i) one type of TLD is not suitable for all children, (ii) the training is insignificant and the application is inappropriate and (iii) participants sometimes use alternative strategies to promote honesty with children.ConclusionPolice officers reported following guidance because a failure to do so would jeopordise children's testimony and provided recommendations for future practice‐informed research designs to test techniques for the promotion of honesty in child witnesses.

Understanding the complexity of young children's learning and development in science: A twofold methodological model building on constructivist and cultural-historical strengths

Abstract Young children's learning and development in Science is a complex process. Although a wide range of epistemological, theoretical and methodological frameworks have informed research in Early Childhood Science Education, capturing this complexity remains a challenge. New ways of conceptualizing and researching young children's engagement with Science are needed for responding to this fundamental challenge. The present study brings together the strengths of constructivist and cultural-historical research perspectives to provide deeper insight and a holistic understanding of the unique way young children experience, make sense of, and conceptualize the natural world. In line with the two basic research approaches, a twofold methodological model is introduced. Empirical data were collected in an early childhood setting during a collective science experience centred on the natural phenomenon of cloud formation. Following a constructivist perspective, the data on children's conceptual understanding of the phenomenon was initially analysed. Then, the same data set was analysed from a cultural-historical perspective. In this second step, the children's whole experience of the phenomenon was also captured. Findings reveal the critical role of the children's overall reality in the science concept formation. The study argues that a dialectical interrelation between the two research perspectives is feasible and essential for understanding children's conceptualizations in the moment, as well as how science concepts are formed in the overall reality of everyday life. This adds to the literature on Early Childhood Science Education, where studies have primarily focused on dividing, rather than bringing together the strengths of the two perspectives. The study contributes to the continual challenge of rethinking and overcoming traditional dichotomies in educational research.

Children's Spontaneous Gestures Reflect Verbal Understanding of the Day/Night Cycle.

Understanding the day/night cycle requires integrating observations of the sky (an Earth-based perspective) with scientific models of the solar system (a space-based perspective). Yet children often fail to make the right connections and resort to non-scientific intuitions – for example, the Sun moving up and down – to explain what they observe. The present research explored whether children’s gestures indicate their conceptual integration of Earth- and space-based perspectives. We coded the spontaneous gestures of 85 third-grade children in U.S. public schools (Mage = 8.87 years) as they verbally explained the overall cause of the day/night cycle, the cause of sunrise, and the cause of sunset after receiving science instruction as part of a prior study. We focused on two kinds of gestures: those reflecting the Sun’s motion across the sky and those reflecting the Earth’s axial rotation. We found that participants were more likely to produce Earth rotation gestures for a topic they explained more accurately (the overall cause of the day/night cycle), whereas Sun motion gestures were more common for topics they explained less accurately (the causes of sunrise and sunset). Further, participants who produced rotation gestures tended to provide more accurate verbal explanations of the overall cause. We discuss how gestures could be used to measure – and possibly improve – children’s conceptual understanding and why sunrise and sunset may be particularly difficult topics to learn.

A Pilot Randomized Controlled Trial Testing the Effectiveness of a Pedestrian Training Program That Teaches Children Where and How to Cross the Street Safely.

Pedestrian injury is a leading cause of injury-related mortality for children. This pilot randomized controlled trial tested the efficacy of a training program to teach where and how to cross safely. Using fully immersive virtual reality technology, 142 children 7-10 years of age were recruited, with 130 completing crossing measures before (pretest) and immediately after (posttest) training. Training comprised 1.5 hr, was tailored to each child's performance over trials, and focused on either where to cross (n = 44 children completed testing) or how to cross safely (n = 43); corresponding control groups comprised 22 and 21 children, respectively. Following training, children in the intervention groups completed additional tasks to test conceptual knowledge and generalization of learning. Children in the control groups spent the same time as those in training groups but played a video game that used the same game controller but provided no training in street crossing. The primary outcomes were errors in crossing at posttest, controlling for pretest error scores. Children in the intervention group made from 75% to 98% fewer errors at posttest than control children for all pedestrian safety variables related to where and how to cross safely, with effect sizes (incidence rate ratios) varying between 0.02 and 0.25. They also showed a generalization of what they had learned and applied this knowledge to novel posttraining situations. Training within a virtual pedestrian environment can successfully improve children's conceptual understanding and crossing behaviors for both where and how to cross streets safely.

Children's understanding of multiplication and division: Insights from a pooled analysis of seven studies conducted across 7years.

Research suggests that children's conceptual understanding of multiplication and division is weak and that it remains poor well into the later elementary school years. Further, children's understanding of fundamental concepts such as inversion and associativity does not improve as they progress from grades 6 to 8. Instead, some children simply possess strong understanding while others do not. Other studies have identified an increase across these grades. The present investigation analyses data from seven studies of Grade 6 (n=226), Grade 7 (n=221), and Grade 8 (n=216) children's three-term problem-solving (e.g., 3×24 ÷ 24 and 3 × 24 ÷ 6) and provides a unified account of multiplication and division understanding, one in which grade differences and individual variability coexist and are moderated by sex. Statement of contribution What is already known on this subject? Children's conceptual understanding of multiplication and division is weak and it is unclear whether it increases across the key grades of 6-8. Understanding of the inversion and associativity concepts is characterized by high individual variability, but grade and sex have never been found to be a contributing factor. What does this study add? A meta-analysis of seven data sets (n=643) indicates that grade differences and individual variability coexist and are moderated by sex. Understanding increases across grade only for boys, but an equal number of boys and girls are in the top 10% of conceptual problem-solvers.

Preschool Students' Understanding of a Geometric Shape, the Square

Abstract The purpose of this study was to explore preschool children's conceptual understanding of geometric shapes, the square in particular. There were a total of 115 children, 61 girls and 54 boys, from state preschool education programs, who participated in the study. The data were collected in two semesters through interviews in a one-on-one setting, where the researchers administered a paper-pencil test to the participants. The test included six questions. One question asked children to draw a square, one question asked to select the square among three other geometric shapes, three questions asked to differentiate the square among five to seven geometric shapes which were printed in rotated directions and in various fonts and sizes and one question asked to identify a picture of a square-like real life object among a selection of pictures. The findings showed that 65% of children were able to draw a square accurately, and 77% of children were able to identify a picture of a square-like object. Approximately 69% were able to differentiate three squares in different sizes among five geometric shapes, while 27% of the remaining were not able to identify the square in smaller sizes. Approximately 79% in one task and 56% in another task were unsuccessful in identifying squares in rotated directions. Moreover, there was no gender difference in the test between boys and girls. Findings were interpreted linking to Duval's theory, van Hiele's theory, Prototype theory and Simon's task design model.

On Being in the Wrong Place: The Role of Children's Conceptual Understanding and Ballgame Experience when Judging a Football Player's Offside Position.

We investigated the role of children’s conceptual understanding and ballgame experience when judging whether a football player is in an offside position, or not. In the offside position, a player takes advantage of being behind the defence line of the opposing team and just waits for the ball to arrive in order to score a goal. We explained the offside rule to 7- and 9-year-old children with a Subbuteo setup. They produced drawings of an offside position until it was correct (drawing to criterion). Thereafter, children judged whether a designated player was in an offside position in a computerized task. Like adults, also children found it easier to judge when a player was in a wrong rather than a right place. Only when including frequency of ballgame practice in the analysis it was revealed that boys were better independently of age as they judged the offside position more systematically.

Young Children's Conceptual Understanding of Triangle

This study explored 5-6 year-old children's conceptual understanding of one geometric shape, the triangle. It focused on whether children could draw a triangle from memory, and identify triangles of different types, sizes, and orientations. The data were collected from 82 children attending state preschool programs through a one-on-one interview, during which children completed five paper-pencil tasks. Findings showed that the majority of the children (93%-96%) successfully identified a prototyped triangle. Approximately half of the children experienced difficulties in identifying triangles of different sizes, types, and orientations. The most difficult area was identifying types of triangles, where an isosceles triangle and a right triangle were presented, followed by identifying triangles in different orientations, specifically flipped and rotated ones. Children appeared to identify and classify the triangle relying on the visual prototype. These findings provide support for the Prototyped Theory, van Hiele theory, and for works by Clement and colleagues.

Promoting Honesty: The Influence of Stories on Children's Lie‐Telling Behaviours and Moral Understanding

Moral stories are a means of communicating the consequences of our actions and emphasizing virtuous behaviour, such as honesty. However, the effect of these stories on children's lie‐telling has yet to be thoroughly explored. The current study investigated the influence of moral stories on children's willingness to lie for another individual. Children were read one of three stories prior to being questioned about an accidental wrongdoing: (1) a positive story, which emphasized the benefits of being honest; (2) a negative story, which outlined the potential costs of lying; and (3) a neutral story, which was unrelated to truth‐telling or lie‐telling. Initially, most children withheld information about the event. Older children were better able to maintain their lies throughout the interview. However, when asked direct questions, children in the positive story condition were more likely to tell the truth than those in the negative and neutral conditions. No significant differences were found between the negative and neutral story conditions. The present study also investigated the relationship between children's conceptual understanding and behaviour. The findings revealed that children's knowledge of truths and lies increased with age. Children who lied had significantly higher conceptual scores than those who did not lie. Furthermore, the type of story children were read had a significant impact on their evaluations of true and false statements. Copyright © 2015 John Wiley & Sons, Ltd.

General and math-specific predictors of sixth-graders’ knowledge of fractions

The present study examined predictors of student's knowledge of fraction concepts and procedures in sixth grade (N=334). Predictors included both math-specific and more general competencies, which were assessed in fifth grade. Multiple regression analyses showed that whole number line estimation, non-symbolic proportional reasoning, long division, working memory, and attentive behavior contributed uniquely to a general measure of students’ fraction concepts; on a measure of fraction procedures, whole number line estimation, multiplication fact fluency, division, and attention made unique contributions. The combined predictability of the measures was lower for fraction procedures than for fraction concepts. Although the unique predictors and the amount of explained variance differed according to the fraction outcome, the ability to locate whole numbers on the number line was a major contributor to prediction in each model. Non-symbolic proportional reasoning was particularly predictive of children's conceptual understanding of fractions.

Understanding early elementary children's conceptual knowledge of plant structure and function through drawings.

This study examined children's drawings to explain children's conceptual understanding of plant structure and function. The study explored whether the children's drawings accurately reflect their conceptual understanding about plants in a manner that can be interpreted by others. Drawing, survey, interview, and observational data were collected from 182 students in grades K and 1 in rural southeastern United States. Results demonstrated the children held a wide range of conceptions concerning plant structure and function. These young children held very simple ideas about plants with respect to both their structure and function. Consistent with the drawings, the interviews presented similar findings.

Designing Science Learning in the First Years of Schooling. An intervention study with sequenced learning material on the topic of ‘floating and sinking'

Research on learning and instruction of science has shown that learning environments applied in preschool and primary school rarely makes use of structured learning materials in problem-based environments although these are decisive quality features for promoting conceptual change and scientific reasoning within early science learning. We thus developed and implemented a science learning environment for children in the first years of schooling which contains structured learning materials with the goal of supporting conceptual change concerning the understanding of the floating and sinking of objects and fostering students' scientific reasoning skills. In the present implementation study, we aim to provide a best-practice example of early science learning. The study was conducted with a sample of 15 classes of the first years of schooling and a total of 244 children. Tests were constructed to measure children's conceptual understanding before and after the implementation. Our results reveal a decrease in children's misconceptions from pretest to posttest. After the curriculum, the children were able to produce significantly more correct predictions about the sinking or floating of objects than before the curriculum and also relative to a control group. Moreover, due to the intervention, the explanations given for their predictions implied a more elaborated concept of material kinds. All in all, a well-structured curriculum promoting comparison and scientific reasoning by means of inquiry learning was shown to support children's conceptual change.

Chinese and Australian Year 3 Children's Conceptual Understanding of Science: A multiple comparative case study

Children have formal science instruction from kindergarten in Australia and from Year 3 in China. The purpose of this research was to explore the impact that different approaches to primary science curricula in China and Australia have on children's conceptual understanding of science. Participants were Year 3 children from three schools of high, medium and low socio-economic status in Hunan Province, central south China (n = 135) and three schools of similar socio-economic status in Western Australia (n = 120). The students' understanding was assessed by a science quiz, developed from past Trends in Mathematics and Science Study science released items for primary children. In-depth interviews were carried out to further explore children's conceptual understanding of living things, the Earth and floating and sinking. The results revealed that Year 3 children from schools of similar socio-economic status in the two countries had similar conceptual understandings of life science, earth science and physical science. Further, in both countries, the higher the socio-economic status of the school, the better the students performed on the science quiz and in interviews. Some idiosyncratic strengths and weaknesses were observed, for example, Chinese Year 3 children showed relative strength in classification of living things, and Australian Year 3 children demonstrated better understanding of floating and sinking, but children in both countries were weak in applying and reasoning with complex concepts in the domain of earth science. The results raise questions about the value of providing a science curriculum in early childhood if it does not make any difference to students' conceptual understanding of science.

The use of additive composition in arithmetic: the case of children classified as low attainers

This study investigated the conceptual understanding that low-attaining children have and are able to use in arithmetic. Fifteen 6–7 year old children solved pairs of conceptually-related addition problems. Conceptual relations between equal problems were constructed to reflect aspects of the principle of additive composition. Children's conceptual understanding was explored by examining their capability to use concept-based approaches in related problems, and ability to recognise and explain additive composition relationships. The findings indicate that, when prompted, children who employ only basic calculation procedures have the capability to recognise and use additive composition relations in problem solving. Almost all children showed increased sensitivity to additive composition relations when asked to explain the equality between related problems. Our findings highlight the need to develop pedagogical approaches that instigate low-attaining children's conceptual capabilities and support the operationalisation of these in the kinds of concept-based strategies that are most typically ascribed to high-attaining children.

Individual differences in conceptual and procedural knowledge when learning fractions.

Previous research on children's conceptual and procedural understanding of fractions, and other arithmetic skills, has led to contradictory conclusions. Some research suggests that children learn conceptual knowledge before procedural knowledge, some suggests that they learn procedural knowledge before conceptual knowledge, and other research suggests that they learn conceptual knowledge and procedural knowledge in tandem. We propose that these contradictory findings may be explained by considering individual differences in the way that children combine conceptual and procedural knowledge. A total of 318 Grade 4 and 5 students in the United Kingdom (mean age = 9.0 years) completed a measure of fractions understanding, which included subscales of conceptual and procedural knowledge. A cluster analysis identified 5 distinct clusters that differed from each other in terms of their relative success with conceptual and procedural problems. The existence of these clusters suggests that there may be more than one way in which children draw on conceptual and procedural knowledge. Some children rely more on procedural knowledge and others more on conceptual knowledge, but these differences may not be related to developmental processes. The children in the 5 clusters differed in their total fractions performance and in their understanding of intensive quantities. These differences suggest that children who rely on conceptual knowledge may have an advantage compared to those who rely more exclusively on procedural knowledge.

Developing children's conceptual understanding of area measurement: A curriculum and teaching experiment

The present study examined the effectiveness of three instructional treatments which had different combinations of mathematical elements regarding 2-dimensional (2-D) geometry and area measurement for developing 4th-grade children's understanding of the formulas for area measurement and their ability to solve area measurement problems. Participants were 120 fourth graders. The results showed that the enriched curriculum, involving the geometry motions and area measurement connections effectively facilitated children's mathematical judgments and explanations demanding high-level conceptual understanding. The instructional curricula accentuating only 2-D geometry or numerical calculations for area measurement did not exhibit such effectiveness. Interview data revealed that the geometric operations of superimposition, decomposition, re-composition as well as the concept of congruence were deemed essential by children for the conceptualization of the formulas for area measurement.

Evaluation of a pilot study on student's conceptual understanding and practical skills acquisition of dietary knowledge

This study is a trial pilot study that investigated if there is a relationship between the method of teaching dietary knowledge in the classroom and students' conceptual understanding and practical skills acquisition of dietary knowledge of children aged 10–11 years. The research was carried out in a school within the Healthy School Scheme Award in rural mid Wales, United Kingdom. The methodology included eliciting the conceptions held by students on the concept of balanced diet and healthy eating using questionnaire, diary and interview before and after a teaching intervention on the concept of balanced diet. The teaching intervention involved comparing a Teaching/Learning Sequence (TLS) with the Regular Teaching Method (RTM) to determine if there will be increase in both conceptual understanding of dietary knowledge and encouragement of healthy eating habits. Parental influence as well as their opinion about their children's conceptual understanding of healthy eating was also elicited via parent questionnaire. The findings from this study clearly indicated some fundamental flaws and misconceptions in participants' knowledge and understanding of balanced diet in both TLS and RTM groups before the intervention but after the intervention, there was a statistically significant improvement of the TLS group over the RTM group and participants opting for healthier snack (less sugar/fat snack). A high percentage of the sampled parents agreed that children should be encourage to cook at home though some considered it to be too risky. The conclusion and implication of this study is that the contexts in which students learn about healthy eating are key factors in determining how receptive they are to nutrition education. The policies that a school adopts, the physical and social environment it provides, the curriculum it chooses, and the quality and methods of instruction all have the potential to significantly affect nutrition education.

Predictors of early numeracy: Is there a place for mistakes when learning about number?

It is one thing to be able to count and share items proficiently, but it is another thing to know how counting and sharing establish and identify quantity. The aim of the study was to identify which measures of numerical knowledge predict children's success on simple number problems, where counting and set equivalence are at issue. Seventy‐two 5‐year‐olds were given a battery of nine tasks on each of three sessions (at 3‐monthly intervals). Tasks measured procedural proficiency, conceptual understanding (using an error‐detection paradigm) and the ability to compare sets using number knowledge. Procedural skills remained fairly stable over the 6‐month period, and preceded children's ability to detect another's violations to those procedures. Regression analysis revealed that children who are sensitive to procedural errors in another's counting and sharing are more likely to recognize the significance of cardinal numbers for set comparisons. We suggest that although children's conceptual understanding of well‐rehearsed routines is often limited, conceptual insight might be achieved by setting tasks that require reflection rather than practice.

The Origins of the Concept Mapping Tool and the Continuing Evolution of the Tool

A research program at Cornell University that sought to study the ability of children to acquire science concepts and the effect of this learning on later schooling led to the need for a new tool to describe explicit changes in children's conceptual understanding. Concept mapping was invented in 1972 to meet this need, and subsequently numerous other uses have been found for this tool. Underlying the research program and the development of the concept mapping tool was an explicit cognitive psychology of learning and an explicit constructivist epistemology. In 1987, collaboration began between Novak and Cañas and others at the Florida Institute for Human and Machine Cognition, then part of the University of West Florida. Extending the use of concept mapping to other applications such as the integration of concept mapping with the World Wide Web (WWW) led to the development of software that enhanced the potential of concept mapping, evolving into the current version of CmapTools now used worldwide in schools, universities, corporations, and governmental and non-governmental agencies. Differences between concept maps and other knowledge representation tools are described. The integration of concept mapping software programs with the WWW and other new technologies permits a new kind of concept map-centred learning environment wherein learners build their own knowledge models, individually or collaboratively, and these can serve as a basis for life-long meaningful learning. Combined with other educational practices, use of CmapTools permits a New Model for Education. Preliminary studies are underway to assess the possibilities of this New Model.

Individual differences in children's understanding of inversion and arithmetical skill

Background and aims. In order to develop arithmetic expertise, children must understand arithmetic principles, such as the inverse relationship between addition and subtraction, in addition to learning calculation skills. We report two experiments that investigate children's understanding of the principle of inversion and the relationship between their conceptual understanding and arithmetical skills. A group of 127 children from primary schools took part in the study. The children were from 2 age groups (6-7 and 8-9 years). Children's accuracy on inverse and control problems in a variety of presentation formats and in canonical and non-canonical forms was measured. Tests of general arithmetic ability were also administered. Children consistently performed better on inverse than control problems, which indicates that they could make use of the inverse principle. Presentation format affected performance: picture presentation allowed children to apply their conceptual understanding flexibly regardless of the problem type, while word problems restricted their ability to use their conceptual knowledge. Cluster analyses revealed three subgroups with different profiles of conceptual understanding and arithmetical skill. Children in the 'high ability' and 'low ability' groups showed conceptual understanding that was in-line with their arithmetical skill, whilst a 3rd group of children had more advanced conceptual understanding than arithmetical skill. The three subgroups may represent different points along a single developmental path or distinct developmental paths. The discovery of the existence of the three groups has important consequences for education. It demonstrates the importance of considering the pattern of individual children's conceptual understanding and problem-solving skills.
