A promising science and literacy instructional model with Hispanic fifth grade students

Abstract

This study evaluated the Science and Literacy Instructional Model aimed at helping primarily Hispanic bilingual/English Learners (ELs) and economically disadvantaged fifth grade students with science achievement as measured by high-stakes standardized science achievement scores. The model combined purposeful planning, innovative academic vocabulary instruction, and a Lesson Design Lab. Difference-in proportions tests were used to determine if students at two school campuses showed positive achievement gains on a state science test. This study found statistically significant results with medium to large effect sizes at both campuses. Findings contribute to much needed research, practice, and policy in the area of effective models to assist both teachers and students in an era of high-stakes testing.     

Extinction of the overshadowing CS after overshadowing in conditioned taste aversion

Using a conditioned taste aversion preparation overshadowing of flavor-illness association was produced through the presentation of a second flavor during the interval between the first flavor and illness. The modulatory effects of extinguishing the association between the second (over-shadowing) flavor and illness on conditioned responding to the target flavor was investigated. In Experiment 1, we found that, following one-trial overshadowing, extinction of the overshadowing flavor had no effect on conditioned responding to the target flavor. In Experiment 2, we found a similar absence of an effect of extinction of the overshadowing stimulus in a multitrial over-shadowing paradigm. Experiment 3 confirmed the results of Experiments 1 and 2 using conditioning parameters that were designed to weaken the association between the overshadowed flavor and illness. In Experiments 4 and 5, we used simultaneous presentation of the flavors during conditioning and obtained a weakened aversion to the overshadowed flavor when the overshadowing CS was extinguished. These findings are inconsistent with previous observations in conditioned fear preparations that suggest that extinction of the association between the overshadowing stimulus and the unconditioned stimulus attenuates overshadowing. Possible reasons for the discrepant results are discussed.     

The Effects of Pre‐School Experience on Reading Attainment: a four year cross‐sectional study

This paper examines the reading attainments of a sample of Year 2 children who had one of three types of preschool experience. The results of a 4‐year cross‐sectional study of a sample of all Year 2 children (n = 834) from six randomly selected primary schools within one Local Education Authority (LEA) are presented. The children had attended nursery or playgroup or experienced no preschool provision outside the home: they were not matched for social background. Pupils’ scores on The Primary Reading Test (PRT) [France, N. (1981) The Primary Reading Test (Windsor, NFER/Nelson] are compared over the 4 years, as are the reading Standardised Assessment Task (SAT) scores of the last two cohorts. Results are not clear cut. For 3 of the 4 years, the group with no‐preschool experience performed significantly less well than at least one of the other two groups with some type of preschool experience on the PRT. The SAT levels of nursery children were significantly higher than those of the other two groups. Conclusions, based on such a small study, are tentative. It appears that preschool provision has an effect on children's reading attainments and that this is still significant in Year 2. The validity of the SAT is considered as a factor in the relative reading attainments of the three groups.     

‘Here I come again’: the cost of success for higher education students diagnosed with autism

This qualitative study used Interpretative Phenomenological Analysis to consult with 16 autistic UK higher education (HE) students about their experiences of success. An in-depth participatory approach encouraged participants to become co-analysts of their data.

Participants offered counter-narratives to deficit-based interpretations of autism, giving accounts of making themselves ‘extra-visible’ as autistic in order to assert their rights. The autism diagnosis was perceived both as an aid to self-understanding and a cause of additional barriers. In raising awareness of their own needs, participants contributed to broader understandings of autism within their academic communities, inadvertently becoming educators and role models. The research highlights the extra effort required by autistic students to thrive within higher education and the barriers imposed by current requirements to both pursue formal diagnosis, and to disclose it in order to receive adjustments. The research was novel in its approach and in its focus on success, revealing original findings in relation to the challenges and barriers faced by high-achieving autistic students, and the implications for a more inclusive higher education curriculum and environment are considered.     

Recommendations of school students with autism spectrum disorder and their parents in regard to bullying and cyberbullying prevention and intervention

Accumulating evidence suggests that the prevalence of bullying is significantly higher for students with Autism Spectrum Disorder (ASD) than for typically developing students. Additionally, the prominence and growth of social networking and resultant focus on cyberbullying in the last 10 years has added a new dimension to the traditional definitions, environments and experiences of bullying. This paper describes current anti-bullying strategies and the legal climate in regard to bullying in Australia. It then reports on interviews with 10 students with ASD and their parents, and discusses recommendations based on their perceptions for dealing with bullying in schools. Data analysis indicated that both students and parents made a range of recommendations to increase awareness of bullying; improve policies and procedures that can be more clearly communicated to students, teachers and parents; and support programmes that develop communication and relationship building within families and in schools to both prevent bullying and provide coping strategies to deal with bullying if it occurs. Parents also called for schools to give harsher penalties for offenders, particularly repeat offenders. These student and parent recommendations may contribute to the development of school and government policy and practice to help reduce the incidence of all forms of bullying in schools.     

The Open Learning Initiative: A successful marketing strategy or a devaluation of the Australian system of higher education?

The Open Learning Initiative (OLI) which resulted in the Australian Federal Government setting up a brokering company now known as Open Learning Australia (OLA), first opened its doors in March 1993. Since that time, educators, administrators, politicians and student groups have followed its development with considerable interest. The need to monitor and evaluate this new initiative was given high priority, hence the studies conducted by the Senate Standing Committee on Employment, Education and Training and the University of Melbourne's Centre for the Study of Higher Education. OLA is now into its third year of operation and its final year of Government financial support. By now it is perhaps becoming more apparent just what are its achievements and what are the areas of concern being raised by critics, observers and stakeholders in relation to its impact on Australian higher education.     

Faculty-student engagement in teaching observation and assessment: a Hong Kong initiative

There is now a worldwide focus on the quality of university teaching and yet there is general dissatisfaction in universities with the student evaluation of teaching system. Peer observation of teaching seems to hold much promise in the assessment of teaching quality, but such observation pays little attention to the quality of teaching as perceived by students. One approach to overcome this deficiency is for faculty and students to also partner in the assessment of a faculty member’s teaching, with a student trained in observation and feedback techniques acting as a peer in the observation process. This paper describes and evaluates an ongoing student consultant initiative at Lingnan University in Hong Kong. It presents faculty and student observations in terms of the benefits to faculty regarding potential enhancement of university teaching, and the benefits to students especially in terms of close collaboration with faculty and training in consultation techniques. The paper notes that the student consultant initiative has been more popular with students than faculty, and recommends further investigation of the potential of such programmes in Hong Kong higher education.
