We review the state of genetics instruction in the United States through the lens of backward design, with particular attention to the goals and assessments that inform curricular practice. An analysis of syllabi and leading textbooks indicates that genetics instruction focuses most strongly on foundations of DNA and Mendelian genetics. At the same time, a survey of faculty indicates that other concepts, such as the application of genetics to society or the environment, are viewed as equally or even more important than foundation concepts. This disconnect suggests a need for more explicit goal setting prior to curriculum development. We also review the relationship between concept inventories, multiple-choice tests measuring conceptual understanding, and curricular goals. Existing concept inventories offer a strong foundation on which to build community-developed concept assessments of genetics knowledge. Concept assessments such as these would allow the genetics education community to test hypotheses of curricular change. 相似文献

Although many self-identified bisexual individuals report having at least one child, bisexual parents’ unique experiences, including sexuality-related communication with their children, have been largely absent from the parenting literature. We conducted in-depth interviews via telephone (or digital telephony such as voice over Internet protocol) with 33 individuals who self-identified as bisexual were at least 18 years old, had at least one child (genetic, adopted, step, foster, guardian or partner’s child) and currently living in the USA. Nearly all participants encouraged their children to be tolerant of sexual and gender diversity. Sexual behaviours were primarily discussed in terms of protection from sexually transmitted infections and unintended pregnancy. Participants’ approaches to communication included non-verbal methods (e.g. role modelling) and pragmatic verbal discussion. Participants employed numerous strategies, including age-appropriate, child-driven and opportunistic discussions. Some parents did not discuss sexuality at all with their children. Many had not received training in childhood development or sexuality education. The participants’ experiences were often similar to previous research on parents of other sexual identities. However, due to the unique stigma associated with bisexuality, findings point to a need for developing and providing targeted resources for bisexual parents to assist in discussions about sexuality within the family context. 相似文献

We study the relationship between parental job loss and children's academic achievement using data on job loss and grade retention from the 1996, 2001, and 2004 panels of the Survey of Income and Program Participation. We find that a parental job loss increases the probability of children's grade retention by 0.8 percentage points, or around 15%. After conditioning on child fixed effects, there is no evidence of significantly increased grade retention prior to the job loss, suggesting a causal link running from the parental employment shock to children's academic difficulties. 相似文献

We characterized college human genetics courses for nonscience majors (NSM) by 1) determining the number of U.S. institutions offering courses and the number of students taking them; and 2) surveying course instructors on course demographics, content, materials, and pedagogies. Between 2002 and 2004, an estimated 480 institutions of higher education (15.2%) offered a course: 8.4% of 1667 associate colleges, 16.1% of baccalaureate institutions, 25.3% of master's institutions, and 32.9% of doctoral institutions. This indicates a need to increase access to genetics education in 2-yr colleges. Based on instructor responses, approximately 32,000–37,000 students annually complete an NSM human genetics course out of approximately 1.9 million students earning a college degree each year (2.0%). Regarding course content, instructors consistently rated many concepts significantly higher in importance than the emphasis placed on those concepts in their courses. Although time could be a factor, instructors need guidance in the integration of the various concepts into their courses. Considering only 30.2% of the instructors were reportedly trained in genetics (another 25.4% in molecular and cellular biology) and the small fraction of students completing NSM human genetics courses, these results demonstrate the need for increasing the availability of these courses in undergraduate institutions of higher education, and particularly at 2-yr colleges. 相似文献

Student ratings of teaching effectiveness are widely used to make judgments of faculty teaching performance. Research, however, has found that such ratings may not be accurate indicators of teaching performance because they are contaminated by course easiness. Using student ratings of 9855 professors employed at 79 different colleges and universities, the author hypothesized and found that the relationship between perceived course easiness and perceived course quality was moderated by school academic rankings. More specifically, easiness ratings were more strongly correlated with quality ratings among low‐ranked schools than among high‐ranked schools. Furthermore, the easiness–quality relationship was slightly stronger among public schools than among private schools. The article concludes by discussing the practical implications of these findings. 相似文献

This study examined the predictive utility of five formative reading measures: words correct per minute, number of comprehension questions correct, reading comprehension rate, number of maze correct responses, and maze accurate response rate (MARR). Broad Reading cluster scores obtained via the Woodcock–Johnson III (WJ III) Tests of Achievement served as the criterion variable. Examiners administered all reading measures to 98 students enrolled in upper elementary (UES) and middle school (MS) grades (grades 4 through 8). Results indicated significant intercorrelations within all predictor variables for the combined and UES samples; fewer intercorrelations existed at the MS level. MARR exhibited the highest correlation with WJ III Broad Reading across all correlational analyses. Additional regression analyses indicated that the MARR technique best predicted WJ III Broad Reading cluster scores across all groups analyzed. Limitations of the current study and suggestions for future research are discussed. 相似文献

Many studies have found gender differences in certain areas of academic achievement, such as reading and math. Fewer studies have examined gender disparities in writing skills. The current study explored gender differences in written expression performance. Participants were 1,240 male and female students in third through eighth grade, representing five schools in a rural southeastern school district. Each student was administered an AIMSweb curriculum‐based measurement writing probe during the district's regularly scheduled fall, winter, and spring benchmarks. All measures were scored for total words written and correct writing sequences. Two‐way repeated measures analyses of variance were used to determine whether differences existed in the sample. A significant female advantage was found on both scoring indices at each grade level. These findings have strong instructional and theoretical implications for practicing school psychologists and other educators. 相似文献

Teacher referrals for consultation resulted in two independent teams collecting evidence that allowed for a treatment component evaluation of color wheel (CW) procedures and/or interdependent group‐oriented reward (IGOR) procedures on inappropriate vocalizations in one third‐ and one first‐grade classroom. Both studies involved the application of B‐C‐D‐C designs, with the initial B phase involving the application of independent group‐oriented punishment (IGOP) procedures that were applied in all classrooms at the respective schools and maintained across all phases of the studies. In Study I, the C phase involved that application of IGOP, IGOR, and CW; CW was withdrawn in the D phase and reinstated in the subsequent C phase. In Study II, IGOP procedures were supplemented with CW procedures (first C phase), then IGOR procedures were added (D phase) and withdrawn (second C phase). Results from the two studies converge and provide evidence that CW procedures are effective when applied with IGOP procedures and that supplementing them with IGOR procedures may have little classwide impact on inappropriate vocalizations. © 2010 Wiley Periodicals, Inc. 相似文献
