Impact of Secondary Students’ Content Knowledge on Their Communication Skills in Science

The expert blind spot (EBS) hypothesis implies that even some experts with a high content knowledge might have problems in science communication because they are using the structure of the content rather than their addressee’s prerequisites as an orientation. But is that also true for students? Explaining science to peers is a crucial part of cooperative learning methods such as the “jigsaw method”. Our study examined the relationship between science communication competence (SCC) and content knowledge (CK) of 10th-grade students (N = 213). Using latent class analysis, we identified two types of students with a different relationship between CK and SCC. Using path analysis, we found that the first type of 109 students primarily used their science CK as the “resource” for addressee-oriented science communication and both their SCC and their CK were correlated with each other. For the second type of 104 students (who used other resources), their CK even had a small negative effect on their SCC. Using t tests, we found that those students primarily using their CK as the resource for communication performed significantly worse in the communication test than did those students who used other resources. Using the EBS hypothesis, we suggest that students’ CK might have ambiguous effects in communication if the content structure—rather than their addressee’s prior knowledge—is used as the primary orientation for communication. We suggest that an effective use of cooperative learning techniques in classroom requires a special prior training for their science communication skills.     

Teaching Linear Functions in Context with Graphics Calculators: Students’ Responses and the Impact of the Approach on Their Use of Algebraic Symbols

This study analyses some of the consequences of adopting a functional/modelling approach to the teaching of algebra. The teaching of one class of 17 students was observed over five weeks, with 15 students undertaking both pre- and post-tests and 6 students and the teacher being interviewed individually. Use of graphics calculators made the predominantly graphical approach feasible. Students made considerable progress in describing linear relationships algebraically. They commented favourably on several aspects of learning concepts through problems in real contexts and were able to set up equations to solve contextualised problems. Three features of the program exerted a triple influence on students use and understanding of algebraic symbols. Students concern to express features of the context was evident in some responses, as was the influence of particular contexts selected. Use of graphics calculators affected some students choice of letters. The functional approach was evident in the meanings ascribed to letters and rules. Students were very positively disposed to the calculators, and interesting differences were observed between the confidence with which they asked questions about the technology and the diffidence with which they asked mathematical questions.

Knowledge Restructuring in the Development of Children’s Cosmologies

The development of children’s cosmologies was investigated over a 13‐year period, using multi‐modal, in‐depth interviews with 686 children (217 boys, 227 girls from New Zealand and 129 boys, 113 girls from China), aged 2–18. Children were interviewed while they observed the apparent motion of the Sun and Moon, and other features of the Earth; drew their ideas of the shape and motion of the Earth, Moon and Sun, and the causes of daytime and night‐time; then modelled them using play‐dough; which led into discussion of related ideas. These interviews revealed that children’s cosmologies were far richer than previously thought and surprisingly similar in developmental trends across the two cultures. There was persuasive evidence of three types of conceptual change: a long‐term process (over years) similar to weak restructuring; a medium‐term process (over months) akin to radical restructuring; and a dynamic form of conceptual crystallisation (often in seconds) whereby previously unconnected/conflicting concepts gel to bring new meaning to previously isolated ideas. The interview technique enabled the researchers to ascertain children’s concepts from intuitive, cultural, and scientific levels. The evidence supports the argument that children have coherent cosmologies that they actively create to make sense of the world rather than fragmented, incoherent “knowledge‐in‐pieces”.     

Investigating the Impact of NGSS-Aligned Professional Development on PreK-3 Teachers’ Science Content Knowledge and Pedagogy

This pilot study investigates the impact of a 2-week professional development Summer Institute on PK-3 teachers’ knowledge and practices. This Summer Institute is a component of [program], a large-scale early-childhood science project that aims to transform PK-3 science teaching. The mixed-methods study examined concept maps, lesson plans, and classroom observations to measure possible changes in PK-3 teachers’ science content knowledge and classroom practice from 11 teachers who attended the 2014 Summer Institute. Analysis of the concept maps demonstrated statistically significant growth in teachers’ science content knowledge. Analysis of teachers’ lesson plans demonstrated that the teachers could design high quality science inquiry lessons aligned to the Next Generation Science Standards following the professional development. Finally, examination of teachers’ pre- and post-Summer Institute videotaped inquiry lessons showed evidence that teachers were incorporating new inquiry practices into their teaching, especially regarding classroom discourse. Our results suggest that an immersive inquiry experience is effective at beginning a shift towards reform-aligned science and engineering instruction but that early elementary educators require additional support for full mastery.     

Impact of Contact With Grandparents on Children's and Adolescents’ Views on the Elderly

Stereotypes, prejudice, and discrimination against the elderly (ageism) may manifest themselves in children at an early age. However, the factors influencing this phenomenon are not well known. Using both explicit and open-ended questions, this study analyzed the influence of personal and familial parameters on the views of 1,151 seven- to sixteen-year-old Belgian children and adolescents on the elderly. Four factors were found to affect these views: gender (girls had slightly more positive views than boys), age (ageism was lowest in 10- to 12-year-old, reminiscent of other forms of stereotypes and cognitive developmental theories), grandparents’ health, and most importantly, quality of contact with grandparents (very good and good contacts correlated with more favorable feelings toward the elderly, especially in children with frequent contacts).     

The Impact of Learner’s Prior Knowledge on Their Use of Chemistry Computer Simulations: A Case Study

It is complicated to design a computer simulation that adapts to students with different characteristics. This study documented cases that show how college students’ prior chemistry knowledge level affected their interaction with peers and their approach to solving problems with the use of computer simulations that were designed to learn electrochemistry. Students with different prior knowledge levels were found to use different approaches to solving problems with the use of computer simulations. In particular, the cases showed that students with a high level of prior knowledge tended to use the equations and formulas to accomplish the learning tasks and then use the computer simulations to confirm their predictions. Students with a low level of prior chemistry knowledge used the computer simulations as the main resources to accomplish their tasks. Considerations of individual differences and the integration of learning materials were suggested for further research on instructional use of computer simulations.     

Single Mothers’ Experiences of Support at Their Young Children’s School: An Interpretative Phenomenological Approach

This phenomenological study explored six single mothers’ experiences of support at their young children’s school. Themes resulting from interpretative phenomenological analysis suggest the single mothers experienced tangible (e.g., school resources, school-wide events, structural flexibility, teachers’ formal communication) and intangible (e.g., caring relationships with school faculty and staff, experiencing teachers as parenting partners, perceiving acceptance from the school environment) forms of support from their children’s school. Furthermore, results suggest these single mothers experienced intangible supports more prominently than tangible forms of support. The support needs of these single mothers at their young children’s school were also explored including the mothers’ desire for stronger relationships with other parents and families at the school.     

University Lecturers’ Experiences of and Reflections on the Development of Their Pedagogical Competency

In this paper, we investigate university lecturers’ experiences of and reflections on the development of their pedagogical competency during a 9-month university pedagogical course. The effects of long-term university pedagogical training are considered through experienced pedagogical competency by analysing university lecturers’ evaluations of and reflections on their pedagogical competence areas during the course. Data was gathered from 31 participants using a self-evaluation questionnaire and reflective writings, and analysed using a mixed-methods approach. The results show that the participants experienced significant development in their pedagogical competency. However, it became evident that the concept and practice of reflection is not clear, especially in different disciplines. In addition to the number of credits of the training, the design, and the long timeframe of the pedagogical training, the context in which the training is put into practice, as well as the social aspect of reflection, need to be taken into consideration.

The Impact of School-Based Mentoring on Adolescents’ Social–Emotional Health

In order to support at-risk adolescents in their transition to high school, a school-based mentoring program was implemented for a group of 9th and 10th grade students. Due to the need for greater clarity regarding the impact of school-based mentoring on youth outcomes, a quasi-experimental study was conducted to examine the impact of one-to-one mentoring on students’ social–emotional health. Strengths-based survey data were collected from participants at pre-intervention and post-intervention. Findings suggested that school-based mentoring is a promising practice for improving the social–emotional strengths of adolescents and/or protecting them from the risks associated with adolescence.

Mothers’ Perceptions of the Climate of Their Children’s Schools: Covariations With Children’s Academic Adjustment in Families of Mexican Origin

Although Latinx parents’ perceptions of the climate of their children’s schools may play a role in their children’s academic adjustment, research examining this idea is sparse. Every 2 years beginning when children were in fifth grade (M_age = 10.86 years) until they were in 11th grade, Mexican-origin mothers (N = 674) reported on their perceptions of the climate of their children’s schools; information on children’s academic adjustment was collected from children and mothers. Multilevel modeling indicated that when mothers had more positive school climate perceptions, their children valued school more and performed better in school, but did not necessarily hold higher educational expectations. The findings suggest the importance of schools in creating welcoming environments for Mexican-origin parents.     

Finnish Mothers’ and Fathers’ Constructions of and Emotions in Their Daily Lives

This article focuses on parents’ construction of and emotions in their everyday lives. The study brings into focus the meanings in the foreground of everyday life, while also revealing new insights into cultural beliefs and prejudices. Interviews were conducted with five nuclear and four divorced families, and each participant (N?=?18) was interviewed twice. The second interview was a photo-narrative interview, for which each participant took photographs pertaining to their daily life. Content and thematic analysis were applied to the data. Three main categories of everyday life emerged from the data: family daily life, couples’ daily life, and one’s own daily life. The importance of and pleasure derived from one’s own daily life were emphasized as the foundation of well-being for both the individual and the whole family.     

What Counts? Sources of Knowledge in Children’s Acquisition of the Successor Function

Although many U.S. children can count sets by 4 years, it is not until 5½–6 years that they understand how counting relates to number—that is, that adding 1 to a set necessitates counting up one number. This study examined two knowledge sources that 3½- to 6-year-olds (N = 136) may leverage to acquire this “successor function”: (a) mastery of productive rules governing count list generation; and (b) training with “+1” math facts. Both productive counting and “+1” math facts were related to understanding that adding 1 to sets entails counting up one number in the count list; however, even children with robust successor knowledge struggled with its arithmetic expression, suggesting they do not generalize the successor function from “+1” math facts.     

Mothers’ Experiences of Children in the Autistic Spectrum in Greece: Narratives of Development,Education and Disability Across their Blogs

Autism occupies a prominent place in scientific research both as a medical and as a socio-cultural phenomenon. Autism is studied as a disorder and a diagnostic label, as an experience of people with autism, their parents and their supporters, and finally as a disability related to stigma and rejection. The purpose of this article is to describe the posted experiences on personal blogs of five mothers who have school-aged children in the autistic spectrum in Greece. The qualitative method of content analysis is used for analysing the personal narratives across their blogs because this method focuses on describing and understanding the presented experiences and acknowledges the central role of the researcher in describing and signifying the issues discussed. The results of the content analysis show that the mothers seem to view autism through a developmental perspective and as they lead efforts for their child’s developmental timeline they are worried about their child’s developmental course and tend to experience high levels of anxiety, depression and burnout. The mothers act as practical scientists and co-therapists, taking an active role in educating and raising their children, finding a school and selecting appropriate interventions. The mothers struggle to obtain quality in education and services, while faced with the absence of technical infrastructure and understaffing in schools, lack of funding, covert or overt practices of acceptance and rejection of people with disabilities in the educational system, the attitudes and ignorance of some educators, and the high cost of private services. These mothers, at first, view autism as a tragedy and within their social environment they face covert or overt rejection since their children are stigmatised as “abnormal”. Later on, the mothers accept their child’s disability as a prerequisite for gaining a new life experience. It seems that the mothers have a mixed perception of disability, which sometimes tends to be closer to the medical model, sometimes to the hybrid model, while other times to the social model of disability.     

On the Operationalisation of Conceptions of Learning in Higher Education and Their Association with Students’ Knowledge and Experiences of Their Learning

Conceptions of learning, as well as other associated aspects of prior knowledge, are theoretically important factors in influencing the manner in which the content and context of learning are engaged. The present study reports on: (a) the operationalisation of some of these factors aimed at isolating sources of explanatory variation that can be used for modelling purposes; and (b) a conservative exploration of the discriminatory power of, and exhibited patterns of association between, such sources of variation as have been isolated. Based on a conservative analytical approach, the results of the present study do not support a single clearly defined empirical model of conceptions of learning and associated constructs. Instead, there is consistent evidence that underlying empirical structures appear to be sensitive to the response context and other factors.     

The Impact of Learning Communities on First Year Students’ Growth and Development in College

This study investigated the direct and indirect relationships between participating in a learning community, student engagement, and self-reported learning outcomes. Using a sample of 241 freshmen at a single urban research university who took the College Student Experiences Questionnaire, the results indicate that after controlling for demographic characteristics and entering composite ACT score, the relationship between learning community participation and learning outcomes are mediated by students’ levels of engagement. Learning community participation was not directly related to educational gains but was indirectly related to educational gains through student engagement. Student engagement in turn was strongly related to educational gains.     

Impact of multimedia on students’ perceptions of the learning environment in mathematics classrooms

We investigated (1) whether the learning environment perceptions of students in classes frequently exposed to multimedia differed from those of students in classes that were not, (2) whether exposure to multimedia was differentially effective for males and females and (3) relationships between students’ perceptions of the learning environment and student engagement in classes that were exposed to multimedia. The sample involved 365 high-school students in 16 classes, nine that were frequently exposed to multimedia and seven that were not. Two instruments were administered to students: one to assess students’ perceptions of the learning environment and another to assess student engagement. There were statistically significant differences between the two groups for all of the learning environment scales, as well as statistically significant interactions between exposure to multimedia and sex for three learning environment scales (Involvement, Task Orientation and Equity). Finally, the learning environment in mathematics classes that involved multimedia was related to student engagement. These results offer potentially important insights into how student exposure to multimedia could promote more positive learning environments and improve student engagement in mathematics.
