Hands‐on learning is a proven method of improving students’ critical thinking skills. Undergraduate research projects are encouraged to help students develop research and laboratory skills. If properly designed and implemented, research opportunities can be embedded in existing student coursework, which increases the number of students who can participate in these research opportunities. Objectives of this study were twofold: (a) to determine students’ perceptions of an undergraduate research laboratory exercise and (b) provide an innovative laboratory exercise for instructors to implement in their own classrooms. Rolled cookies were prepared by a food science class according to American Association of Cereal Chemists Method 10–50.05, using sucrose and alternative sweeteners and evaluated for physicochemical and organoleptic attributes. After completing the exercise, students evaluated cookie physical/organoleptic properties using a hedonic scale, were asked about personal demographics, and were surveyed about research/writing skills and food processing knowledge using a Likert scale. Approximately 50% of the class responded to the 2018 survey and nearly 85% responded to the 2019 survey. On average, 81.6% of students responded with “Strongly Agree” or “Somewhat Agree” to all survey questions, including data collection and analysis, critical thinking skills, experimental design, and replications. Students responded that detailed instructions provided by instructors were beneficial to their ability to understand experimental design, scientific communication, and the importance of using scientific resources. 相似文献

Children's and adolescents' social reasoning about exclusion was assessed in three different social contexts. Participants (N = 294) at three ages, 10 years (4th grade), 13.7 years (7th grade), and 16.2 years (10th grade), fairly evenly divided by gender, from four ethnic groups, European-American (n = 109), African-American (n = 96), and a combined sample of Asian-American and Latin-American participants (n = 89) were interviewed regarding their social reasoning about exclusion based on group membership, gender, and race. The contexts for exclusion were friendship, peer, and school. Significant patterns of reasoning about exclusion were found for the context, the target (gender or race) of exclusion, and the degree to which social influence, authority expectations, and cultural norms explained children's judgments. There were also significant differences depending on the gender, age, and ethnicity of the participants. The findings support our theoretical proposal that exclusion is a multifaceted phenomenon and that different forms of reasoning are brought to bear on the issue. This model was drawn from social-cognitive domain theory, social psychological theories of stereotype knowledge and intergroup relationships, and developmental studies on peer relationships. The results contribute to an understanding of the factors involved in the developmental emergence of judgments about exclusion based on group membership as well as to the phenomena of prejudice, discrimination, and the fair treatment of others. 相似文献

This review examines contemporary issues in vocational development with emphasis on adolescents' work experiences in social context. Attention is directed to the changing social and cultural context for vocational development, the influence of work experience on adolescent development and educational achievement, and theoretical approaches that guide contemporary studies of vocational development and career maturity. In light of the utility of current theories, new directions are suggested to enhance understanding of adolescent employment, vocational development, and educational pursuits. Social policy initiatives to promote adolescents' exercise of agency and their vocational development are considered. 相似文献

Summary Adults have tried to identify and to seek complex explanations for Potter's success. She explained it simply: “It is much
more satisfactory to address a real live child. I often think that was the secret of the success of Peter Rabbit; it was written
to a child—not made to order” (Lane, 1976, p. 183). She felt the more spontaneous the pleasure, the better the result.
You are encouraged to heed Potter's advice. Address the real live child as you enjoy the pleasure of this adventure into the
life and times of Beatrix Potter and all her animal friends. 相似文献

Children (N = 267, ages 8–14 years, M = 11.61 years, middle to upper-middle income) made predictions regarding groups of same-aged peers from high-wealth and low-wealth backgrounds. The context involved granting access to a special opportunity. From middle childhood to early adolescence children increasingly expected both high- and low-wealth groups to want access to opportunities for their own group. However, children viewed high-wealth groups as motivated in part by selfishness and low-wealth groups as concerned in part with broader economic inequality. Finally, the higher children's family income, the more they expected group-serving tendencies. These findings revealed children's perceptions of exclusive preferences between economic groups, negative stereotypes about high-wealth children, and awareness of some of the constraints faced by low-wealth children. 相似文献

The Developing Inclusive Youth program is a classroom-based, individually administered video tool that depicts peer-based social and racial exclusion, combined with teacher-led discussions. A multisite randomized control trial was implemented with 983 participants (502 females; 58.5% White, 41.5% Ethnic/racial minority; Mage = 9.64 years) in 48 third-, fourth-, and fifth-grade classrooms across six schools. Children in the program were more likely to view interracial and same-race peer exclusion as wrong, associate positive traits with peers of different racial, ethnic, and gender backgrounds, and report play with peers from diverse backgrounds than were children in the control group. Many approaches are necessary to achieve antiracism in schools. This intervention is one component of this goal for developmental science. 相似文献

Most graduate programs in management require students to carry out a substantive research project. However, few management students have a comfortable command of the statistical techniques needed to realize such quantitative projects. This can lead to student anxiety and stress, which challenges instructors to devise ways to build students’ self-efficacy with statistical analysis. Drawing on game-based learning principles, we developed an exercise to help students in a graduate-level research methods course practice these statistical techniques. Designed around a series of four gamified challenges, students perform basic statistical analyses (correlations, t-tests, and simple linear regression) to solve puzzles and unlock a reward hidden in a mysterious red envelope. We used the exercise on seven occasions (five times in the methods course and twice in a graduate program preparatory course). After launching it in fall 2021, we observed that students were engaged and enthusiastic about the exercise. To ascertain its effectiveness more systematically, we collected data in five subsequent sections using a pretest/posttest design (N = 84) which showed that perceptions of statistics self-efficacy increased following the exercise. We conclude by suggesting that our exercise can be tailored to other learning contexts such as management and statistics-centered courses. 相似文献

A large number of American elementary school students are now studying science using the hands‐on inquiry curricula developed in the 1990s: Insights; Full Option Science System (FOSS); and Science and Technology for Children (STC). A goal of these programs, echoed in the National Science Education Standards, is that children should gain “abilities to do scientific inquiry” and “understanding about scientific inquiry.” We have studied the degree to which students can do inquiries by using four hands‐on performance assessments, which required one or three class periods. To be fair, the assessments avoided content that is studied in depth in the hands‐on programs. For a sample of about 1000 fifth grade students, we compared the performance of students in hands‐on curricula with an equal number of students with textbook curricula. The students were from 41 classrooms in nine school districts. The results show little or no curricular effect. There was a strong dependence on students' cognitive ability, as measured with a standard multiple‐choice instrument. There was no significant difference between boys and girls. Also, there was no difference on a multiple‐choice test, which used items released from the Trends in International Mathematics and Science Study (TIMSS). It is not completely clear whether the lack of difference on the performance assessments was a consequence of the assessments, the curricula, and/or the teaching. © 2006 Wiley Periodicals, Inc.
