Teaching statistics in biology: using inquiry-based learning to strengthen understanding of statistical analysis in biology laboratory courses

There is an increasing need for students in the biological sciences to build a strong foundation in quantitative approaches to data analyses. Although most science, engineering, and math field majors are required to take at least one statistics course, statistical analysis is poorly integrated into undergraduate biology course work, particularly at the lower-division level. Elements of statistics were incorporated into an introductory biology course, including a review of statistics concepts and opportunity for students to perform statistical analysis in a biological context. Learning gains were measured with an 11-item statistics learning survey instrument developed for the course. Students showed a statistically significant 25% (p < 0.005) increase in statistics knowledge after completing introductory biology. Students improved their scores on the survey after completing introductory biology, even if they had previously completed an introductory statistics course (9%, improvement p < 0.005). Students retested 1 yr after completing introductory biology showed no loss of their statistics knowledge as measured by this instrument, suggesting that the use of statistics in biology course work may aid long-term retention of statistics knowledge. No statistically significant differences in learning were detected between male and female students in the study.     

Conceptual and empirical differences among various value-added models for accountability

Accountability systems in education generally include indicators of student performance. However, these indicators often differ considerably among the various systems. More and more countries try to include value-added measures, mainly because they do not want to hold schools accountable for differences in their initial intake of students. This study presents a conceptual framework of these value-added measures, resulting in an overview of 5 different types. Using data from Dutch secondary schools, we empirically provide estimates of these different measures. Our analyses show that the correlation between the different types of school effects estimated is rather high, but that the different models implicate different results for individual schools. Based on theoretical considerations, arguments are given to use the following indicators in the value-added accountability models: prior achievement, student-level background characteristics, and compositional characteristics of the student population.     

Bachelor-master Programmes in the Netherlands and Germany

This article compares the results ofthe implementation of the new bachelor-mastersystem in the Netherlands and Germany. TheBologna Process presents the common Europeancontext for this reform process. However, therespective national contexts differ, and so dothe actual implementation processes and theemerging outcomes. For each of the twocountries, a limited number of aspects of thereforms that emerged as most relevant arehighlighted. In the final section, somecommonalities and differences are discussed.The former mainly concern the characteristicsof the binary system in both countries and theintroduction of accreditation in relation tothe bachelor-master system. With respect to thelatter, the implementation strategy and thefunding conditions are most strikinglydifferent, related to the fact that in Germanythe new system is implemented in parallel withthe existing system, whereas in theNetherlands the new system will replace theexisting one.     

Factors Contributing to the Level of Acceptance of Technology in Affluent Private Schools

Abstract

This research was conducted to explore factors that influence the technology acceptance of teachers who are employed at a school where there is wide access to different types of technology. While previous research identified perceived ease of use and perceived usefulness as variables in technology acceptance, not many studies give details about the determining factors of teachers who are given extensive access to a wide variety of educational technology. The researcher therefore aimed to identify distinct aspects that deter the use of the available technology, while also establishing the motivating factors in the target school. Semistructured interviews were conducted with five divergent volunteers. The transcribed interviews were analyzed qualitatively using Atlas.ti to assist in identifying emerging patterns. Through the analyses it became evident that although teachers are presented with technology and recognize the usefulness thereof, flaws in support from the institution are increasingly deterring even teachers with a high technology acceptance from using available technology. It is the researchers’ recommendation that members of management set clear implementation goals to staff members, while dedicating themselves to prioritizing issues such as infrastructure, maintenance of hardware, and effective training opportunities.

Do teachers differ in the level of expectations or in the extent to which they differentiate in expectations? Relations between teacher-level expectations,teacher background and beliefs,and subsequent student performance

ABSTRACT

Previous studies have indicated that, although some teachers have substantial expectation effects on student outcomes, the effects for most teachers are only small. Furthermore, teacher expectations are associated with key pedagogical differences related to teacher beliefs about providing instruction and support for learning. The aim of this study was to explore (a) teacher-level differences in the level and differentiation of expectations, (b) associations between teacher differences in expectations and teacher background and beliefs, and (c) relationships with subsequent student performance. Secondary analyses were performed on data for 42 teachers and their students in New Zealand. The results were supportive of the notion that some teachers were differentiating more between students in their expectations than others. Teachers who differentiated more perceived students generally as more competent, but felt less related to the school team, and perceived more classroom stress. Differentiation in expectations was negatively related to end-of-year mathematics scores.

Dominant achievement goals across tracks in high school

The dominant achievement goals (DAGs) of 7008 students in the third grade of Dutch secondary education (US grade 9) were investigated, based on Elliot & McGregors’ 2 × 2 framework (2001), in relation to track-level and motivational variables. We found the mastery-approach goal and the performance-approach goal, generally considered adaptive, to be more prominent among students in lower tracks. In contrast, avoidance goals were more common in higher tracks. Most notably, in the highest track, the mastery-avoidance goal was the most prominent. Additionally, we found that students with a dominant performance-approach goal scored highest on almost all motivational variables examined; students without a DAG scored mostly second highest. The implications of these findings are discussed.     

Teachers’ Attitudes Toward Multiculturalism in Relation to General and Diversity-Related Burnout

This study focuses on teachers’ general and diversity-related burnout in relation to teachers’ attitudes toward multiculturalism. Results are based on the responses of 120 teachers working at five different urban, ethnically diverse junior vocational high schools in the Netherlands. Analyses indicated that teachers with assimilative attitudes exhibited higher levels of general and diversity-related burnout, whereas there was no relationship between pluralistic attitudes and burnout. In addition, there were no relationships between teacher background variables and attitude and burnout, besides the finding that native teachers experienced less general burnout, and had less pluralistic attitudes, than nonnative teachers.
