The Role of Informal Support Networks in Teaching the Nature of Science

This study reports the participation of 13 secondary science teachers in informal support networks and how that participation was associated with their nature of science (NOS) teaching practices 2 to 5 years after having graduated from the same science teacher education program. The nine teachers who participated in informal support networks taught the NOS at high/medium levels, while the four non-participating teachers taught the NOS at low levels. The nine high/medium NOS implementation teachers credited the informal support networks for maintaining/heightening their sense of responsibility for teaching NOS and for helping them navigate institutional constraints that impede effective NOS instruction. Several high/medium NOS instruction implementers initially struggled to autonomously frame and resolve the complexities experienced in schools and thus drew from the support networks to engage in more sophisticated forms of teacher decision-making. In contrast, the NOS pedagogical decisions of the four teachers not participating in support networks were governed primarily by the expectations and constraints experienced in their schools. Implications of this study include the need for reconsidering the structure of teacher mentorship programs to ensure they do not promote archaic science teaching practices that are at odds with reform efforts in science education.

     

Conditions for young infants' perception of object trajectories

When an object moves behind an occluder and re-emerges, 4-month-old infants perceive trajectory continuity only when the occluder is narrow, raising the question of whether time or distance out of sight is the important constraining variable. One hundred and forty 4-month-olds were tested in five experiments aimed to disambiguate time and distance out of sight. Manipulating the object's visible speed had no effect on infants' responses, but reducing occlusion time by increasing object speed while occluded induced perception of trajectory continuity. In contrast, slowing the ball while it was behind a narrow or intermediate screen did not modify performance. It is concluded that 4-month-olds perceive trajectory continuity when time or distance out of sight is short.     

Undergraduate research experience for future science teachers: A first effort

Conclusion As a means of providing some insights into the research activity for future science teachers, the project was a qualified success. Throughout its inception and implementation there remained an uneasy compromise between conducting a piece of worthwhile research and providing the maximum possible range of experiences for the students undertaking the subject. The experience undoubtedly was valuable for the students, it provided them with insights which served as the bases for developing individual research proposals, for the evaluation of a curriculum change in a secondary school. In general, through, the scope of the project was too ambitious for the time that was available and this led to a feeling of frustration, if not in the students, certainly in the authors. The investigation itself suffered from obvious limitations which have been discussed above. However, the gains observed in favour of the class using SCIS materials are congruent with those identified by a four-year longitudinal study conducted by Renner et al. (1973) and suggest that a more rigorous investigation is warranted. It may be possible to engage our under-graduate students in a longitudinal study of the effectiveness of SCIS by involving different groups at different stages of the project. We believe that the first attempt has shown that it is a worthwhile component of pre-service teacher education.

Pretend play and patterns of cognition in Down's syndrome children

This study was designed to examine the relationship between cognitive functioning of Down's syndrome subjects as measured by the Bayley Scales of Infant Development and their symbolic play level. Subjects ranged in chronological age from 20 to 53 months and in mental age from 12 to 26 months. Each child was seen at home with the mother or primary caretaker present. A 1/2-hour play session was videotaped, followed by administration of the Bayley Mental Scale and Infant Behavior Record. Analysis of play behavior supported a 4-level scale. Symbolic play level was more highly correlated with mental age than with chronological age. Performance on the Infant Behavior Record was also highly correlated with symbolic play level.     

Reinvigorating adolescent sexuality education through alternate reality games: the case of The Source

This paper presents findings from a focus group study conducted to evaluate The Source, an alternate reality game (ARG). ARGs are a relatively new genre of interactive digital games that use a variety of media to engage game players. We developed modules on sexual health, sexual orientation, and homophobia in a game that was delivered to 133 predominantly African-American and Latino US youth. Ten focus groups were conducted with 43 young people aged 13–18 who played The Source to understand feasibility and acceptability issues and the impact of the game on young people’s attitudes, knowledge, and behaviours. Data were transcribed and analysed for common themes by two independent coders. Four primary themes were identified: (1) the feasibility and acceptability of using an ARG for sexual education; (2) the acceptability of The Source’s specific sexual health content; (3) the game’s influence on sexual health-related knowledge, attitudes, and behaviours; and (4) the impact of the game on young people’s thoughts and responses to sexual orientation and homophobia. Study findings indicate that an ARG is an exciting and interactive way to educate young people on sensitive topics in sexuality education, but that attention to narrative authenticity and effective messaging are important issues to address.     

Role of cognitive prompts in video caregiving training for older adults: optimizing deep and surface learning

Enhancing the cognitive functionality of digital technology can be critical in learning complex topics like caregiving for older adults. This study examines the deployment of cognitive prompts in video-based training to optimize older adults’ cognitive information process in both deep and surface learning. The path analysis revealed the relationship among cognitive prompts, crystallized knowledge and learning outcomes showing crystallized knowledge as a significant mediator between cognitive prompts and learning outcomes. Additionally, cognitive prompts were shown to be significant in activating older learners’ prior knowledge, rendering the learning process more meaningful and purposeful for older adults.
