Money, sex, and drugs: a case study to teach the genetics of antibiotic resistance

The goal of the work reported here was to help students expand their understanding of antibiotic resistance, the Central Dogma, and evolution. We developed a unit entitled "Ciprofloxacin Resistance in Neisseria gonorrhoeae," which was constructed according to the principles of scientific teaching by a team of graduate students, science faculty, and instructors. A variety of activities and assessments were used, including a case study, short lectures, and group problem-solving. Implementation of "Ciprofloxacin Resistance in Neisseria gonorrhoeae" in a college freshman seminar suggests these materials are useful in increasing understanding of complex biological topics and improving problem-solving abilities.     

Connectedness to Campus and Likelihood of Help-Seeking for Suicidality among College Women

The goal of the present study was to examine the link between connectedness to campus and the likelihood of help-seeking from a mental health professional/school counselor for thoughts of suicide among college women. An online survey was administered to college students to assess perceived likelihood of seeking help, feelings of connectedness to campus, sense of togetherness with peers, and presence of a supportive group of friends on campus. Findings indicated that feeling connected to campus was positively associated with perceived likelihood of help-seeking for suicidal ideation. Furthermore, this association was stronger among participants reporting either a sense of togetherness with peers or a supportive group of friends. Efforts to increase students’ sense of connection to the larger campus community and build peer relationships may promote help-seeking for suicidal ideation among college women.     

Can middle‐school science textbooks help students learn important ideas? Findings from project 2061's curriculum evaluation study: Life science

The transfer of matter and energy from one organism to another and between organisms and their physical setting is a fundamental concept in life science. Not surprisingly, this concept is common to the Benchmarks for Science Literacy (American Association for the Advancement of Science, 1993 ), the National Science Education Standards (National Research Council, 1996 ), and most state frameworks and likely to appear in any middle‐school science curriculum material. Nonetheless, while topics such as photosynthesis and cellular respiration have been taught for many years, research on student learning indicates that students have difficulties learning these ideas. In this study, nine middle‐school curriculum materials—both widely used and newly developed—were examined in detail for their support of student learning ideas concerning matter and energy transformations in ecosystems specified in the national standards documents. The analysis procedure used in this study was previously developed and field tested by Project 2061 of the AAAS on a variety of curriculum materials. According to our findings, currently available curriculum materials provide little support for the attainment of the key ideas chosen for this study. In general, these materials do not take into account students' prior knowledge, lack representations to clarify abstract ideas, and are deficient in phenomena that can be explained by the key ideas and hence can make them plausible. This article concludes with a discussion of the implications of this study to curriculum development, teaching, and science education research based on shortcomings in today's curricula. © 2004 Wiley Periodicals, Inc.

Facilitating Student Learning,the Assessment of Learning,and Curricular Improvement Through a Graduate Social Work Integrative Seminar

Social work programs undertake to educate competent professionals and to promote critical thinking among students who are expected to become lifelong learners. In addition, programs are called on to develop reliable and valid measures for assessing student learning outcomes and to use assessment results to reflect upon and strengthen curriculum. This study explores the use of a graduate integrative seminar to accomplish these goals. The authors describe the learning and assessment processes of the seminar. The authors used a mixed-method research design to analyze data from students over a 3-year period regarding the effectiveness of the seminar as well as from graduate faculty regarding student achievement of curricular objectives. Results indicate that formative assessment processes promote student learning in a manner that mobilizes students to strive for excellence, and that an embedded measure of learning outcomes in the form of a final integrative project may serve as a rigorous assessment tool.     

Understanding how educational maths apps can enhance learning: A content analysis and qualitative comparative analysis

Educational applications (apps) are ubiquitous within children's learning environments and emerging evidence has demonstrated their efficacy. However, it remains unclear what the active ingredients (ie, mechanisms), or combination of ingredients, of successful maths apps are. The current study developed a new, open-access, three-step framework for assessing the educational value of maths apps, comprised of type of app, mathematical content and app design features. When applied to a selection of available maths apps previously evaluated with children in the first 3 years of school (the final sample included 23 apps), results showed that practice-based apps were the most common app type tested (n = 15). Basic number skills, such as number representation and relationships, were the most common area of mathematics targeted by apps (n = 21). A follow-up qualitative comparative analysis showed observed learning outcomes with maths apps were enhanced when apps combined the following: a scaffolded and personalised learning journey (programmatic levelling) and explanations of why answers were right or wrong (explanatory feedback), as well as praise, such as ‘Great job!’ (motivational feedback). This novel evidence stresses the significance of feedback and levelling design features that teaching practitioners and other stakeholders should consider when deciding which apps to use with young children. Directions for future research are discussed.

Practitioner notes

What is already known about this topic

• Educational apps have been shown to support maths attainment in the first 3 years of school.
• Several existing frameworks have attempted to assess the educational value of some of these maths apps.
• Emerging experimental evidence also demonstrates the benefits of specific app design features, including feedback and levelling.

What this paper adds

• Practice-based maths apps are the most common type of app previously evaluated with young children.
• These evaluated maths apps have mostly focused on basic number skills.
• The combination of explanatory and motivational feedback, with programmatic levelling (either dynamic or static), was a necessary condition for enhancing learning outcomes with maths apps.

Implications for practice and policy

• The inclusion of feedback and levelling in maths apps should be considered by app developers when designing apps, and by educational practitioners and parents when deciding which apps to use with their children.
• Further consideration is also needed for the development of educational apps that include a broad range of maths skills.

     

A Training Performance Indicator Model For Monitoring the Effectiveness of High–Risk Training: Report of a Study in Progress

High–risk operations, including the nation's commercial nuclear power industry, are devoting extensive resources and leadership to improve human performance through training. The evaluation of the effectiveness of this training is the focus of on–going research. This report summarizes the methodology of a research study in progress at one nuclear utility and de scribes a training performance indicator model that was developed during the study. The model organizes the types of performance indicators currently thought to be worthwhile in monitoring training effectiveness. The model contains twelve categories of indicators. Each category is described and illustrated in this report.
