In a Food Processing–Unit Operations course, students learn the basic equipment that comprises unit operations and techniques commonly used in the food industry to prepare, process, and preserve a variety of food products. Due to the complexity of these operations, students frequently struggle with applying food processing principles to predict how unit operations influence the physical, biochemical, sensory, and nutritional properties of foods. This study is designed to evaluate how pre‐class readings and in‐class group activities improve the students’ learning in a Food Processing course. The survey after the exams shows that 48 and 60% of students agree that reading assignments and in‐class group activities help them understand the course material better, respectively. The mean value of exam scores shows that the students in the intervention section (Spring 2018) had significantly higher scores (88.4%) than that of the two previous sections without intervention (77.6%, Spring 2016 and 82.8%, Spring 2017) (P < .05). It is concluded that using a flipped class element like providing reading assignments and quizzes before the lecture can be an effective preparation technique for students as well as providing the instructors with critical insight into the students’ level of understanding before the lecture. This allows the instructor to focus time spent in class on areas in which students struggle the most.  相似文献

Effects of extended training (nine sessions, 50 trials each) on two-way avoidance response latencies were studied. For each rat, auditory and visual warning signals (CS) were presented on separate trials, either according to a Gellermann series or in 25-trial blocks. Intermittent presentation of the two kinds of trials yielded shorter latencies and higher levels of avoidance performance in response to the noise CS than in response to the darkness CS. Presentation of trials in blocks revealed stronger response-eliciting properties of stimuli presented during the second half of the session than of those presented during the first half. A significant decrease of avoidance performance in the early portions of the delay period, an index of inhibition of delay, was obtained on auditory trials presented in the second half of the sessions. Results indicate that strong fear of the warning signal is required for inhibition of delay of avoidance responses.  相似文献

Students’ perceptions of actual and preferred classroom environment were investigated using the What is happening in this class? questionnaire (WIHIC). The WIHIC assesses seven classroom environment dimensions: student cohesiveness, teacher support, involvement, task orientation, investigation, cooperation and equity. A sample of 978 secondary school students from 63 classes in Queensland responded to the WIHIC. For each item on the WIHIC, students recorded their perceptions of the actual (or real) and preferred (or ideal) classroom environment. Results revealed that statistically significant differences between actual and preferred environments, and that the gap between actual and preferred environment was smaller for more positive classroom environments.  相似文献

Risk behavior was investigated among 1,053 Danish adolescents aged 12–20. Driving a car while intoxicated was rare even among the oldest adolescents, but riding a bicycle while intoxicated was reported by the majority of adolescents aged 14–20. Driving a car at high speeds was widespread among the oldest adolescents (aged 18–20), but still lower than rates reported for same-age American adolescents. Rates of sex without contraception were higher than expected, in spite of early and extensive sex education, while rates of illegal drug use other than marijuana were extremely low. Participation in risk behavior was analyzed in relation to sensation seeking, city size, and various family variables. Results are discussed in the context of the theory of broad and narrow socialization, in which a cultural and multidimensional understanding of socialization is emphasized.  相似文献

In this study we examined the effect of heart rate and behavioral measures of attention on distractibility of 6-, 9-, and 12-month-old infants. The infants were presented with a toy, and a distractor was presented while they attended to the toy. The distractor was presented during heart rate changes indicating sustained attention or attention termination, or during periods of time when behavioral ratings indicated the infant was in focused or casual attention. There were longer distraction latencies during attentional engagement as defined by heart rate changes or behavioral ratings than for periods of inattention. Infants had the longest distraction latencies when heart rate and behavior measures were congruent with respect to attention engagement (heart rate deceleration and focused attention). Conversely, latencies were shortes for congruent values of inattention (heart rate acceleration and casual attention). Infant information processing may be greatest when a heart rate deceleration occurs simultaneously with an episode of focused attention.  相似文献

Large‐scale research projects, conducted in a cross‐European context, are increasingly attractive to educational researchers and policy‐makers. However, this form of comparative research across cultures brings problems concerning the standardization of data collection and analysis, particularly where ethnographic research is concerned, as it prioritizes a full range of qualitative research strategies. This paper outlines the use of a universal model and the approaches recently taken by two research teams and contrasts these with another recent nine‐partner comparative European study that used ethnographic methods. We then describe the analytical procedures used in the project, which encouraged participant observation and individual researcher interpretation in order to generate grounded accounts and outline how they were culturally sensitive and meaningful to research teams who used varied analytical approaches. However, this raised difficult issues for the ‘final’ analysis and the production of a loosely coupled research report. Our pragmatic solution was a process of ‘qualitative synthesis’ whereby individual partner reports were collated by the Project Director and treated as data and a grounded theory approach was applied to generate tentative theory in respect of creative learning. The paper concludes by arguing that data generated by a loosely coupled approach to qualitative comparative research which uses a wide range of data collection methods can be effectively analysed with a qualitative synthesis.  相似文献

The Reconstruction of Primary Teachers' Identities   总被引:3,自引:0,他引:3  
Primary teachers have had to reconstruct their identities in response to the reconstruction of the education system. The holism, humanism and vocationalism of the old Plowden self-identity has been challenged by a new assigned social identity signalled in the assault on child-centred philosophy, the diminution of elementary trust, and changes in the teacher role. These challenges have thrown up new dilemmas for teachers, and represent 'fateful moments' in the careers of their identities. In trying to resolve the dilemmas, teachers have engaged in identity work, characterised mainly by identity talk, and a number of emotional and intellectual strategies. The result has been a partitioning of the old Plowden self-identity, with the 'real self' being largely withheld from the new personal identity and the sense of vocationalism being set to one side. The new personal identity in teaching represents a more instrumental and situational outlook, with the substantial self finding more expression elsewhere. Identity work is still in progress and seems set to continue while teachers have to find ways of relating to two or more competing discourses.  相似文献

Planning and organizing the young child's curriculum and classroom environment is an essential component in the early childhood education program. Every fall in the USA millions of children begin and continue to participate in formal school settings. These children are all unique and differ in cognitive and social maturity.Jeffrey I.
