Learning to play: A review and theoretical investigation of the developmental mechanisms and functions of cetacean play

Play is a behavioral phenomenon most commonly observed in the young of both solitary and social species. Documentation of play in cetaceans varies across species and settings. Cetacean play behavioral repertoires include a broad range of actions, such as the manipulation of diverse objects, blowing bubbles, chasing conspecifics, and swimming in spirals through the water. As is common in research on animal play, cetacean play has been grouped into categories by its form, including locomotor play, object play, and different variations of social play, such as affiliative games, play fighting, and socio-sexual play. Research has primarily focused on recording the topography of cetacean play and the demographics of the individuals engaging in play. However, these classifications are insufficient to address the possible developmental and societal functions of cetacean play behaviors, or the mechanisms with which play behaviors are spread between conspecifics and acquired by young members of cetacean populations. This article applies several developmental and social learning theories in order to organize current knowledge and guide future research.     

Patterns of participation in year 9 academic testing and factors predicting absence on the day of test

Policies aiming to improve educational outcomes are typically based on academic testing data. However, such data only reflect the performance of students who completed the tests. It is possible that students who were absent have shared characteristics. The proportion of students absent out of all eligible school students and whether they have shared characteristics has not been investigated, as this is only possible through the use of linked administrative data. Participants were born in Western Australia in 1994 and 1995, and their birth records were linked to participation status in the Year 9 academic tests to determine the proportion of students who were absent. Logistic regression was conducted to investigate characteristics which predicted absence on test day. A proportion of non-Aboriginal (3.2 %) and Aboriginal students (21.9 %) were absent on test day. Risk factors which predicted the absence included contact with Child Protection and Family Services, history of maternal mental health problems, and fathers aged below 20 years at the time of their child’s birth. A significant proportion of students was absent and therefore not represented in academic achievement information. These students were more likely to have experienced adverse events and therefore are not randomly absent. As these data are typically used to inform policies which aim to improve educational outcomes, they may lack the necessary information to adequately address the complex needs of students who are absent on test day. However, findings suggest that service providers, as well as schools may play an important role in encouraging participation in school.     

Understanding Linear Function: a Comparison of Selected Textbooks from England and Shanghai

This study describes a comparison of how worked examples in selected textbooks from England and Shanghai presented possible learning trajectories towards understanding linear function. Six selected English textbooks and one Shanghai compulsory textbook were analysed with regards to the understanding required for pure mathematics knowledge in linear function. Understanding was defined as being at five levels: Dependent Relationship, Connecting Representations, Local Properties Noticing, Object Analysis and Inventising. These levels were developed by examining the most prominent theories from the existing literature on understanding function. Findings suggested that the English textbooks constrained the structural aspect of understanding linear function due to a point-to-point view of function, while the Shanghai textbook which focussed on a variable view of function overemphasised the algebraic approach. The discussion explored the drawbacks to each approach and what teachers or textbook writers could do to balance these two approaches in order to facilitate students’ understanding towards a structural view of linear function.     

Implications of a Cognitive Science Model Integrating Literacy in Science on Achievement in Science and Reading: Direct Effects in Grades 3–5 with Transfer to Grades 6–7

Reported are the results of a multiyear study in which reading comprehension and writing were integrated within an in-depth science instructional model (Science IDEAS) in daily 1.5 to 2 h daily lessons on a schoolwide basis in grades 3–4–5. Multilevel (HLM7) achievement findings showed the experimental intervention resulted in significant and consistent direct effects in grades 3–4–5 and complementary transfer effects in grades 6–7 on both ITBS Science (+1.08 Grade Equivalent Units [GE]) and ITBS Reading (+.57 GE). Discussed are implications of the findings and related research for changing grade K-5 curriculum policy to allocate increased instructional time for integrated science instruction.     

Physical Sciences Preservice Teachers’ Religious and Scientific Views Regarding the Origin of the Universe and Life

This paper explores final-year physical sciences preservice teachers’ religious and scientific views regarding the origin of the universe and life. Data was obtained from 10 preservice teachers from individual in-depth interviews conducted at the end of the Science Method module. Their viewpoints were analyzed using coding, sorting, and categorizing. They attributed the origin of the universe and life to a blend of theistic, intelligent design or scientific beliefs. Moreover, their academic backgrounds, exposure to topics in Cosmology in the Science Method module, and classroom dialogues did not significantly influence or change their original religious beliefs. However, the dialogues did create an awareness of their own reflected positions regarding the tenacity of beliefs in religion and their inadequate cosmological understandings. The paper has implications for Science Education in addressing preservice teachers’ religious beliefs in contrast to scientific evidence.     

Reciprocal learning: One teacher’s narrative

This paper is a personal narrative from the perspective of one teacher in Toronto who participated in the Canada–China Reciprocal Learning in Teacher Education and School Education Partnership Grant Project. I took part in a Sister School partnership between 2013 and 2017. Over the four years, I came to understand relationships in an international professional learning community. Participating in the project gave me the benefit of seeing my practice through an international lens. For my students, it offered a global citizenship experience. Although there are numerous professional development opportunities in Toronto, this partnership extends beyond a lunch and learn, or a full day professional learning. The commitment to my partners has fueled my desire to incorporate new teaching ideas and has required ongoing reflection on my own teaching practice. In this article, I will explain some of the challenges, stages of development, reciprocal learning, and implications for future international professional learning communities.
