The Nature–Nurture Question: Teachers’ perceptions of how genes and the environment influence educationally relevant behaviour

Despite a substantial body of research suggesting genetic influence on educationally relevant behavioural traits, it is not clear how the nature–nurture question is perceived by teachers. In order to answer this question, we surveyed 667 UK primary school teachers, and for comparison also surveyed 1,340 parents about their perceptions of genetic and environmental influence on personality, intelligence, behaviour problems, learning difficulties, and mental illness. For these five domains of behaviour, the percentages of teachers who reported that genetics were at least as important as environment were .87, .94, .43, .94, and .91, respectively. Results for parents were similar (.92, .93, .54, .86, and .89). We also found that 80% of teachers reported no coverage of genetics during teacher training.     

An Empirical Investigation Demonstrating the Multidimensional DIF Paradigm: A Cognitive Explanation for DIF

Differential Item Functioning (DIF) is traditionally used to identify different item performance patterns between intact groups, most commonly involving race or sex comparisons. This study advocates expanding the utility of DIF as a step in construct validation. Rather than grouping examinees based on cultural differences, the reference and focal groups are chosen from two extremes along a distinct cognitive dimension that is hypothesized to supplement the dominant latent trait being measured. Specifically, this study investigates DIF between proficient and non-proficient fourth- and seventh-grade writers on open-ended mathematics test items that require students to communicate about mathematics. It is suggested that the occurrence of DIF in this situation actually enhances, rather than detracts from, the construct validity of the test because, according to the National Council of Teachers of Mathematics (NCTM), mathematical communication is an important component of mathematical ability, the dominant construct being assessed. However, the presence of DIF influences the validity of inferences that can be made from test scores and suggests that two scores should be reported, one for general mathematical ability and one for mathematical communication. The fact that currently only one test score is reported, a simple composite of scores on multiple-choice and open-ended items, may lead to incorrect decisions being made about examinees.     

Collaborative Development and Evaluation of an Online Nursing Course

Institutions of higher education acknowledge that online learning represents a growing segment of the modern learning environment, and most students have mastered basic computer skills. However, reluctance to engage in online learning remains among both faculty and students. This article presents a case study of three schools of nursing that collaboratively developed and implemented an online undergraduate-nursing course. The article discusses the challenges that were encountered by faculty and students. The faculty used the distance education literature to address these challenges related to technological, institutional, and pedagogical aspects of online learning, as well as the recruitment and retention of online learners. Quantitative and qualitative methods were used to evaluate the effectiveness of the course. The paper concludes with suggestions to overcome the challenges of online learning, such that faculty and students receive the inherent rewards.     

Knowing and learning about science in a preservice setting: A narrative study

This study employs narrative methods to give a holistic view of the experiences of five mature age preservice teachers in a semester unit of science education. The unit was designed to help teachers examine and make explicit their ideas about science and science teaching and consider ways in which they might put those ideas into practice. The pivotal theme, around which the teachers' experiences could be organised, was found to be learning science. The preservice teachers expressed a need for a supportive learning environment in which concepts were built gradually and introduced using concrete examples. Previous science experience was found to be a major influence on the attitudes the participants brought to the present course. A lack of previous experience or negative past experiences were a major cause of anxiety. Gender was also important as it had limited the science experiences available to some participants in the past and continued to influence the way they participated in classes during the semester. Specializations: primary science, science teacher education, primary school field experience. Specializations: formation of teachers' knowledge, leadership, teacher change, school reform.     

Lamaze breathing: what every pregnant woman needs to know

Lamaze breathing historically is considered the hallmark of Lamaze preparation for childbirth. This column discusses breathing in the larger context of contemporary Lamaze. Controlled breathing enhances relaxation and decreases perception of pain. It is one of many comfort strategies taught in Lamaze classes. In restricted birthing environments, breathing may be the only nonpharmacological comfort strategy available to women. Conscious breathing and relaxation, especially in combination with a wide variety of comfort strategies, can help women avoid unnecessary medical intervention and have a safe, healthy birth.     

Reversing the Downward Spiral of Science Instruction in K-2 Classrooms

This study investigated the extent to which teacher professional development led to changes in science instruction in K-2 classrooms in rural school districts. The research specifically examined changes in (a) teachers’ content knowledge in science; (b) teachers’ self-efficacy related to teaching science; (c) classroom instructional time allotted to science; and (d) instructional strategies used in science. The study also investigated contextual factors contributing to or hindering changes in science instruction. Data sources included a teacher survey, a self-efficacy assessment, content knowledge tests, interviews, and classroom observations. After one year in the program, teachers showed increased content knowledge and self-efficacy in teaching science; they spent more instructional time on science and began using different instructional strategies. Key contextual factors included curricular demands, resources, administrative support, and support from other teachers.     

With Tools and Strategies Teachers Use in Online Courses： A Mexican Public University Case

The rapid development of ICT （information technology and communication） in the last two decades has changed society substantially as a whole. For higher education institutions, the external environment pressure to incorporate ICT in their educational and administrative processes has forced them to invest in resources for infrastructure and training. In addition, teachers have found that they can use technology in their teaching, but lack of full knowledge of how to use it effectively from a pedagogical point of view. The incorporation of new education modalities depends largely on the contextual variables prevailing in the institution and teachers. In UABC （Autonomous University of Baja California）, the early days of online education go hack to 1996, so the study period was from 1996 to 2009. An online survey was designed to fmd out the teachers＇ backgrounds and involvement in online education, their experience as online teachers, and the tools and practices used. Of 97 teachers who were identified with some experience in online teaching, 70% responded to the Survey （68）. It was found that the highest percentage （33%） of teachers who responded the survey started teaching online between 2003 and 2006. 56% of teachers have been teaching between one and five online courses. On the other hand, most teachers recognized that 30%-79% of the content of their courses were online based. The most popular learning management system used is moodle followed by blackboard in teachers＇ preference. In general, teachers expressed using the three main communication tools of online education： forums, chat and e-mail, favoring the use of e-mail. The communication slrategies teachers often use in their courses promoted student-student and student-teacher interaction. In their evaluation strategies, most said that they used self-assessment, rubrics and to a lesser extent online exams and co-evaluation. The results show that most teachers who have been involved in online education in UABC campus have expressed havi
