Effects of training peer tutors in content knowledge versus tutoring skills on giving feedback to help tutees’ complex tasks

This study aimed to investigate the effectiveness of training tutors in content knowledge of a particular domain versus training them in tutoring skills of pedagogical knowledge when tutoring on a complex tutee task. Forty-seven tutor–tutee pairs of fourth-year secondary school students were created and assigned to one of the two treatments. Twenty-two tutors received training in content knowledge and the other twenty-five tutors in tutoring skills. Tutors formulated written feedback immediately after the training. Tutees first interpreted the tutor feedback and then used it to revise their research questions. The results showed that tutors trained in tutoring skills formulated more effective feedback than tutors trained in content knowledge. In addition, tutees helped by tutoring-skills tutors found the feedback more motivating than those helped by content-knowledge tutors. However, no differences were found in tutee performance on revision. The findings are discussed in terms of the set-up of this study and implications for improving the effectiveness of peer tutoring.     

An Evaluation of Two Hands-On Lab Styles for Plant Biodiversity in Undergraduate Biology

We compared learning cycle and expository formats for teaching about plant biodiversity in an inquiry-oriented university biology lab class (n = 465). Both formats had preparatory lab activities, a hands-on lab, and a postlab with reflection and argumentation. Learning was assessed with a lab report, a practical quiz in lab, and a multiple-choice exam in the concurrent lecture. Attitudes toward biology and treatments were also assessed. We used linear mixed-effect models to determine impacts of lab style on lower-order cognition (LO) and higher-order cognition (HO) based on Bloom''s taxonomy. Relative to the expository treatment, the learning cycle treatment had a positive effect on HO and a negative effect on LO included in lab reports; a positive effect on transfer of LO from the lab report to the quiz; negative impacts on LO quiz performance and on attitudes toward the lab; and a higher degree of perceived difficulty. The learning cycle treatment had no influence on transfer of HO from lab report to quiz or exam; quiz performance on HO questions; exam performance on LO and HO questions; and attitudes toward biology as a science. The importance of LO as a foundation for HO relative to these lab styles is addressed.     

The Influence of Creationism and Scientism on Attitudes towards Christianity among Kenyan Secondary School Students

The attitude towards Christianity of 624 form six students in Kenya was measured using the Francis scale of attitude towards Christianity Form ASC4B. Indices were developed to measure the view that science attains to absolute truth, the perception of Christianity as necessarily involving creationism, and personal religious behaviour. Sex, academic achievement, study of religion in form six, study of a science subject in form six, parental educational level and parental church attendance were taken into account in the analysis of the data by path analysis. No significant relationship was found between attitude towards Christianity and perception of Christianity as necessarily involving creationism, but the view of science as attaining to absolute truth does have a negative influence on attitude towards Christianity. The significant influences of students’ sex, mother's educational level and father's church attendance on attitude towards Christianity are all mediated through religious behaviour.     

2-Desoxy-D-glucose as an antagonist of glucose in yeast fermentation

2-Desoxy-D-glucose (2DG) has been found to inhibit strongly the anaerobic fermentation of glucose by living yeast.     

The Challenge of Involving Students in the Evaluation Process

This article traces one teacher educator's efforts to engage a class of pre-service and in-service teachers in the evaluation process. It shows that this is both time-consuming and difficult. It confirms McLaughlin's (1991) assertion that teachers find it difficult to appraise carefully the criteria and standards used to evaluate themselves and their students' learning. It also suggests that there are dimensions of power-knowledge at play at the levels of individual teachers (including the lecturer) and the institution.     

Promoting positive attitudes towards science and religion among sixth‐form pupils: dealing with scientism and creationism

A sample of 187 female students, attending a sixth‐form study day on religious studies, completed a questionnaire containing four scales concerned with assessing: attitude towards theistic religion, attitude towards science, scientism and creationism. The data demonstrated a negative correlation between attitude towards religion and attitude towards science. However, this negative correlation was transformed into a positive correlation after taking into account individual differences in the students’ views about scientism and creationism. The implications of this finding are discussed in the context of the increasing support within society for the teaching of alternatives to evolution within the science curriculum. The authors argue both that it is important to challenge scientism by developing a better understanding of the role and limits of scientific methods, and that religious belief about creation should be recognised as essentially a claim about the ontological dependence of nature rather than about the details of its origins and development.     

The relative effects of group size on reading progress of older students with reading difficulties

This study reports findings on the relative effects from a yearlong secondary intervention contrasting large-group, small-group, and school-provided interventions emphasizing word study, vocabulary development, fluency, and comprehension with seventh- and eighth-graders with reading difficulties. Findings indicate that few statistically significant results or clinically significant gains were associated with group size or intervention. Findings also indicate that a significant acceleration of reading outcomes for seventh- and eighth-graders from high-poverty schools is unlikely to result from a 50 min daily class. Instead, the findings indicate, achieving this outcome will require more comprehensive models including more extensive intervention (e.g., more time, even smaller groups), interventions that are longer in duration (multiple years), and interventions that vary in emphasis based on specific students’ needs (e.g., increased focus on comprehension or word study).     

Early years education in Germany and Ireland — a study of provision and curricular implementation in two unique environments

This paper highlights the differences and similarities between a Kindergarten outside Bremen in Lower Saxony, Germany and a Primary School Junior Infant Class in County Cork, Republic of Ireland. Both are concerned with the education of the young child but whereas the Kindergarten is attended by three to six year olds, the Junior Infant Class caters almost exclusively for four to five year old children.

A case study account of both groups is given and an analysis of the activities which took place in each using the ‘Target Child Observational Schedule’ [Sylva et al., (1980)] is presented in bar‐graph form.

The paper concludes that Erzieherinnen, Kinderpflegerinnen and Junior Infant Class teachers need to engage in more interaction with the children in order, in particular, to raise the frequency and quality of linguistic interaction. An increase in the structure of the children's play would help to enhance cognitive development.     

The validity of discrepancy-based definitions of reading disabilities.

This study addressed the validity of distinguishing children with reading disabilities according to the presence or absence of discrepancies between intelligence test scores and academic achievement. Three definitions of reading disability were used to provide criteria for five groups of children who (a) met a discrepancy-based definition uncorrected for the correlation of IQ and achievement; (b) met a discrepancy-based definition correcting for the correlation of IQ and achievement; (c) met a low achievement definition with no IQ discrepancy; (d) met criteria a and b; and (e) met none of the criteria and had no reading disability. Comparison of these five groups on a set of 10 neuropsychological tests corrected for correlations with IQ showed that group differences were small and accounted for little of the variability among groups. These results question the validity of segregating children with reading deficiencies according to discrepancies with IQ scores.
