Gender Difference in Teachers’ Mathematical Knowledge for Teaching in the Context of Single-Sex Classrooms

This study examines gender differences of teachers on their mathematical knowledge for teaching in the context of single-sex classrooms in Saudi Arabia. A translated version of the Mathematical Knowledge for Teaching (MKT) instrument (Learning Mathematics for Teaching [LMT], 2008) in Number and Operation Content Knowledge (CK) and Knowledge of Content and Student (KCS) scales were administered to 197 teachers (146 male and 51 female). Two-sample t test and multiple regression were conducted to compare the two groups and test the effect of teacher background variables. Female teachers significantly scored better than their male counterpart. Gender, years of teaching experience, and specialization significantly predicted teachers’ content knowledge, F(3, 187) = 13.180, explaining 41.8 % of the variance. Only gender and specialization significantly predicted teachers’ knowledge of content and student, F(2, 191) = 6.335, explaining 24.9 % of the variance. Further comparing items in the MKT instrument where female teachers outperformed male teachers confirmed that female teachers were better in attending to the content knowledge in the context of student’s learning.

     

Translating expertise into effective instruction: The impacts of cognitive task analysis (CTA) on lab report quality and student retention in the biological sciences

Poor instruction has been cited as a primary cause of attrition from STEM majors and a major obstacle to learning for those who stay [Seymour and Hewitt [1997]. Talking about leaving: Why undergraduates leave the sciences. Boulder, CO: Westview]. Using a double‐blind design, this study tests the hypothesis that the lack of explicit instructions in scientific inquiry skills is a major factor in both low STEM retention and academic underperformance. This project delivered supplemental instruction to students in a laboratory‐based undergraduate biology course (n = 314) that was derived either from cognitive task analyses (CTAs) conducted with expert biologists (treatment) or was authored and delivered by an award‐winning biology instructor (control). Students receiving traditional instruction were almost six times more likely to withdraw from the course than students in the treatment condition (8.1% vs. 1.4% of initial enrollment). Of the students who completed the course, those who received the CTA‐based instruction demonstrated significantly higher levels of performance in the discussion section of their written laboratory reports. Significantly higher performances were seen specifically in the areas of analyzing data to formulate valid conclusions, considering alternative explanations, consideration for the limitations of the experimental design and implications of the research. © 2010 Wiley Periodicals, Inc.

Online homework impact in undergraduate mathematics and business statistics courses

This evaluation examines the impact on student success rates related to changes in instructional programmes in undergraduate mathematics and statistics courses. Success for students taking courses with a computer-based homework component was compared with success of students who took the course in prior semesters without the computer-based component. Graphical and analytical tools are used to compare results. Results come from multiple semesters of each type of homework application, for both pre-calculus algebra and business statistics courses. Students whose performance is utilised in this study are undergraduate students taking introductory level college mathematics or business statistics courses, with mostly no prior instruction at this level. Comparing the success of the intervention group with the success of the baseline control group, findings support that the students using the computer-based homework instruction are just as successful as those using the traditional method of homework instruction. Utilising the online homework applications, provide several important advantages in today’s universities, including the reduced time for faculty grading, consistency of graded assignments across all sections of a course and most importantly, immediate feedback for students.     

Developmental Changes in the Relations Between RAN,Phonological Awareness,and Reading in Spanish Children

We examined the developmental relations of phonological awareness (PA) and rapid automatized naming (RAN) with reading in a cross-sectional study with 874 Spanish children from Grades 2 to 6. Our main prediction was that the RAN–reading relationship would decrease due to a gradual change in reading strategy, from serial decoding to sight word reading. Therefore, in contrast to most previous studies, we used discrete reading tasks. Serial RAN tasks for objects, colors, digits, and letters were included. First, we examined whether the RAN tasks loaded on the same constructs across time. An alphanumeric and a nonalphanumeric factor were identified, which were invariant over time. In subsequent multigroup structural equation models we found that the PA–reading relationship was low but slightly increased in the higher grades. As predicted, the RAN–reading relationship decreased for words, whereas the relationship remained stable for pseudowords.     

Reading vocabulary influences in phonological recoding during the development of reading skill: a re-examination of theory and practice

Children’s skill at recoding graphemes to phonemes is widely understood as the driver of their progress in acquiring reading vocabulary. This recoding skill is usually assessed by children’s reading of pseudowords (e.g., yeep) that represent “new words.” This study re-examined the extent to which pseudoword reading is, itself, influenced by orthographic rimes (e.g., eep) of words of the child’s reading vocabulary, during the development of reading skill. In Study 1, children with word reading levels of 6–10 years read matched pseudowords that do and do not share an orthographic rime with words of their reading vocabularies. Study 2 was conducted to further examine such a comparison for children of the 6- to 8-year word reading levels. There was a small and constant advantage of shared lexical orthographic rimes for children with reading levels 6–8 years but from 8 to 10 years that advantage increased significantly, as expected by Ehri’s phase account of word reading development. The pseudoword reading of children learning to read English involves use of lexical orthographic components as well as context-free recoding of graphemes to phonemes. This implies a qualification to the common interpretation of pseudoword reading as a measure of context-free grapheme–phoneme recoding. Such a measure should use selected pseudowords that do not share orthographic rime units or other multigrapheme components with words of the children’s reading vocabularies.     

Social Information Processing,Moral Reasoning,and Emotion Attributions: Relations With Adolescents’ Reactive and Proactive Aggression

Connections between adolescents’ social information processing (SIP), moral reasoning, and emotion attributions and their reactive and proactive aggressive tendencies were assessed. One hundred mostly African American and Latino 13‐ to 18‐year‐olds from a low‐socioeconomic‐status (SES) urban community and their high school teachers participated. Reactive aggression was uniquely related to expected ease in enacting aggression, lower verbal abilities, and hostile attributional biases, and most of these connections were mediated by adolescents’ attention problems. In contrast, proactive aggression was uniquely related to higher verbal abilities and expectations of more positive emotional and material outcomes resulting from aggression. Discussion focused on the utility of assessing both moral and SIP‐related cognitions, and on the potential influence of low‐SES, high‐risk environments on these findings.     

Teachers’ experience with inclusive education in Singapore

Teachers’ positive attitude is most critically and consistently associated with successful inclusion. However, little is known about teachers’ first-hand encounters with inclusive education in Singapore. We present findings from a qualitative study on inclusion based on focus group interviews with 202 teachers from 41 resourced primary schools. The data were transcribed and coded using Interpretive Phenomenological Analysis and NVIVO software. Two broad clusters identified were teachers’ positive and negative experiences in implementing inclusion. More reference was made to negative than positive experiences. The most dominant negative experience was stress from challenging behaviours and instructional difficulties of catering adequately for diverse needs in the same classroom. The most salient positive experience was satisfaction with pupils’ progress and new learning for teachers. Classroom practices that facilitated inclusion and the value of training in shaping teachers’ attitudes towards inclusion were highlighted.     

The evolution of an approach for using analogies in teaching and learning science

An important contribution to effective teaching and learning can be made by teachers' understanding of the central topics in each subject area and knowing how to transform their content knowledge into knowledge for teaching. One aspect of this knowledge is the use of analogies which can effectively communicate concepts to students of particular backgrounds and prerequisite knowledge. Indeed, analogies are considered to be an important component in the repertoire of effective teachers. However, research about teachers' use of analogies in science lessons provides little guidance about the optimum approaches that may be taken by preservice teachers, novice teachers, experienced teachers or reluctant analogy users. This paper describes the evolution of an approach for using analogies in science teaching that addresses both findings from the research literature and recognises the needs of practising teachers.

Curiosity and openmindedness in open and traditional classrooms

In an attempt to determine if an open classroom environment encourages greater curiosity and/or openmindedness than does a traditional classroom environment, 41 open classroom children and 42 traditional classroom children completed an openmindedness scale and 5 subtests of a curiosity scale. Sex was included as a factor and IQ was included as a covariate in all analyses. No significant sex differences were found. The significantly higher mean curiosity score for the open classroom group was primarily due to significant differences between classrooms on 2 of the subtests: those measuring preference for novelty and change (p <.05). The results were interpreted as an indication that the open classroom may encourage some aspects of curiosity to a greater extent than does the traditional classroom.
