Stress and emotions during experiments in biology classes: Does the work setting matter?

Experiments are a complex teaching method carrying a high cognitive load and the risk of failure, which both may induce stress among students. However, it remains unclear if the work setting modulates physiological, subjective, and/or emotional stress responses during experiments. In a randomized experimental field study school students (N = 104) either watched a biology experiment on video (passive condition), conducted the experiment on their own (active condition) or in small groups (interactive condition). Meanwhile, their subjective stress perception, heart rate variability (HRV), salivary cortisol concentration, and achievement emotions were assessed. In the active condition we observed the strongest subjective and HRV stress responses, followed by the interactive condition. Students of the passive condition displayed the weakest stress reactions. Students of the other two conditions showed a weakened diurnal cortisol decrease, indicating more stress. Across conditions, enjoyment dropped and boredom increased, most pronounced in the passive condition. Moreover, there were some associations between subjective, emotional and physiological stress responses. The findings suggest that conducting experiments alone carries the risk of self-attributed failure signified by elevated stress. In contrast, conducting an experiment in a group is less stressful, as others may constitute a source of support. Watching others conduct an experiment carries a low risk of failure and, thus, the lowest stress responses, but comes with the cost of minimized enjoyment and maximized boredom.     

Exploring online students’ self-regulated learning with self-reported surveys and log files: a data mining approach

Many researchers who are interested in studying students’ online self-regulated learning (SRL) have heavily relied on self-reported surveys. Data mining is an alternative technique that can be used to discover students’ SRL patterns from large data logs saved on a course management system. The purpose of this study was to identify students’ online SRL patterns with the use of data mining techniques. We examined both self-reported self-regulation surveys and log files to predict online students’ achievements and found using log files was more powerful in predicting students’ achievements in an online course than self-reported survey data. Discussions to enhance teaching and learning practices with the use of data mining are provided.     

Investigation of the impact of two verbal instruction formats and prior knowledge on student learning in a simulation-based learning environment

This study investigated how the format of verbal instructions in computer simulations and prior knowledge (PK) affected 8th graders' cognitive load (CL) level and achievement in a multimedia learning environment. Although PK was not found to significantly affect student performance and CL level, instruction format was found to impact both. Students who used narrative simulations were found to have a greater CL but also to perform better than those using simulations with on-screen text instructions. However, no significant differences were found between the cognitive efficiency of the two groups. The difficulty of the subject matter and limitations in students' prior content-related knowledge may have increased the intrinsic CL, such that students had difficulty in interpreting the content even if their PK was relatively high. The narrative instructions were more likely than the on-screen text information to reduce the extraneous CL and promote understanding of content. A new measure of cognitive processing is needed to identify the types of CL involved in e-learning and determine the properties of adequate e-learning materials. Finally, the findings of the study are discussed and suggestions for future studies and instructional design are provided.     

Autonomic Regulation on the Stroop Predicts Reading Achievement in School Age Children

In this study we examined high frequency heart rate variability (HF‐HRV, a parasympathetic index) both at rest and during challenge, to assess if variations in cardiovascular activity measured during a Stroop task could be used to predict reading achievement in typically developing children. Reading achievement was examined using the Peabody Individual Achievement Test–Revised. Results showed that greater HF‐HRV suppression during both the Stroop word and Stroop word–color conflict tasks was associated with better reading achievement. Higher basal levels of HF‐HRV did not predict better reading scores. These results are among the first to show a link between HF‐HRV and reading achievement in a normative school age population, and offer new insight into the association between cognitive activity and autonomic regulation of the heart.     

Exploring the links between students' engagement in cooperative learning, their goal preferences and appraisals of instructional conditions in the classroom

Previous research suggested that social support, belongingness and mastery goals were related to the quality of cooperative learning (CL). In this in-depth study we explored how to differentiate between four effective CL teams and four ineffective CL teams, in terms of students' goals and perceptions of instructional conditions. Apart from the earlier mentioned goals we found students' preference for social responsibility, learning for a certificate and entertainment goals to be salient in the CL setting. Mastery and social responsibility goals were prevalent in effective teams, while learning for a certificate and entertainment goals were prevalent in ineffective teams. Moreover, the type of task, group composition and teacher support were mentioned as reasons for effective or ineffective CL.     

Teachers' reflections on cooperative learning: Issues of implementation

Cooperative learning (CL) is a well documented pedagogical practice that promotes academic achievement and socialization, yet many teachers struggle with implementing it in their classes. This study reports on the perceptions of 10, middle-year teachers who implemented cooperative learning in a unit of work across two school terms. Data from the interviews indicated that while the teachers had positive experiences with CL, a number encountered difficulties with implementing it in their classrooms. Issues identified included students socializing during group activities and not working, managing time effectively, and the preparation required. Other issues that the teachers identified as being important for successful group work included the composition of the groups, the task the group was to undertake, the social skills training needed, and the assessment of the learning that occurred in the group.     

The relation between intellectual and metacognitive skills in early adolescence.

The first objective of this study was establishing to what extent metacognitive skill is associated with intelligence. As a second objective, the impact of hints on the execution of metacognitive skills was investigated. Both issues have major implications for the training and transferability of metacognitive skills during performance on a representative school task. First, a standardized intelligence-test was administered to a group of first-year secondary-school students. Next, these students solved six math word problems, three without metacognitive hints and three including these hints. Metacognitive skilfullness was assessed through systematical observation, while learning performance consisted of performance on a math task and grade point average (GPA). Results show that without hints metacognitive skilfulness is the main predictor of initial learning, while intelligence additionally enters the regression equation after the presentation of metacognitive hints. GPA also appears to be predicted by a combination of intellectual and metacognitive skills. Consequences for the early acquisition of metacognitive skills are discussed.     

Group characteristics and profiles of shared regulation in collaborative environments involving asynchronous communication / Características y perfiles grupales de regulación compartida en entornos colaborativos de comunicación asíncrona

The processes of socially shared regulation in small groups of students who perform collaborative tasks through forums involving asynchronous communication are explored in this article. The specific aim of the study is to identify profiles of shared regulation in groups of students who have different performance levels on the task, depending on the regulatory activities exercised by the groups and their distribution over time. For that purpose, a case study was developed; six small groups of university students collaboratively performed a complex task (for 29 days) in a virtual environment based on asynchronous discussion forums. The results revealed three different profiles: (i) a profile with stable and high regulation; (ii) a profile with partially stable and medium regulation; and (iii) a profile with unstable and low regulation. The first two profiles were observed in the groups with high performance levels on the task, while the third profile was observed in the low-performing groups. Therefore, some recommendations are suggested to support processes of shared regulation in asynchronous collaborative learning situations.     

基于奇异值分解熵的心率变异性分析

Assessing the dynamics of heart rate fluctuations can provide valuable information about heart status. In this study, regularity of heart rate variability （HRV） of heart failure patients and healthy persons using the concept of singular value decomposition entropy （SvdEn） is analyzed. SvdEn is calculated from the time series using normalized singular values. The advantage of this method is its simplicity and fast computation. It enables analysis of very short and non-stationary data sets. The results show that SvdEn of patients with congestive heart failure （CHF） shows a low value （SvdEn： 0.056±0.006, p 〈 0.01） which can be completely separated from healthy subjects. In addition, differences of SvdEn values between day and night are found for the healthy groups. SvdEn decreases with age. The lower the SvdEn values, the higher the risk of heart disease. Moreover, SvdEn is associated with the energy of heart rhythm. The results show that using SvdEn for discriminating HRV in different physiological states for clinical applications is feasible and simple.     

Working memory load and automaticity in relation to mental multiplication

The authors’ aim was to examine the relations among mental multiplication, working memory load (WML), and automaticity by alternating the difficulty level of task characteristics. In Experiment 1, involving 30 fifth-grade students with mixed abilities, a 2 (WML) × 2 (automaticity) design was utilized. In Experiment 2, involving 21 high-achieving mathematics learners and 21 low-achieving mathematics learners in Grade 4, a 2 (WML) × 2 (automaticity) × 2 (achievement) design was utilized. Regardless of level of automaticity, individuals under low-WML conditions performed more accurately and faster. Regardless of level of WML, individuals under high automaticity conditions performed more accurately and faster. Group difference was significant. The simple effect of WML was bigger under the conditions with low automaticity, in comparison to the conditions with high automaticity. Alternating difficulty level simultaneously in 2 dimensions of testing conditions posed an amplified impact on the low-achieving group.     

The Influence of Achievement Goal Orientations and Task Concreteness on Situational Interest

This study investigated changes in elementary school students’ (n = 140) situational interest as a function of achievement goal orientation profiles and task characteristics. The authors repeatedly measured situational interest during a simulated science learning task in 2 task conditions that differed in the concreteness of the task elements. The authors identified 3 groups of students with different goal orientation profiles: success-, mastery-, and avoidance-oriented. Results of repeated-measures analysis of covariance showed that students with different profiles displayed different patterns of changes in situational interest in the 2 task conditions. The results confirmed the importance of acknowledging the interaction of student and task characteristics in the arousal and maintenance of situational interest across a learning task.     

Do drawing tasks improve monitoring and control during learning from text?

In two experiments it was investigated how drawing as a monitoring task affects self-regulated learning and cognitive load. To this end, participants (Exp. 1: N = 73, Exp. 2: N = 69) were randomly assigned to one of two conditions. In the experimental condition, students were asked to read an expository text on the formation of polar lights consisting of five paragraphs, whereby, after each paragraph, they had to create a drawing of the text's content. In the control condition, students read the same text, but performed no drawing task. In both conditions, students had to give judgments of learning (JoLs) after each paragraph and after reading the whole text as well as rate their cognitive load. Then, they were asked to select paragraphs for restudy. In Experiment 1, participants continued with an assessment of their learning outcomes immediately after their restudy selection, whereas in Experiment 2 they were first given the opportunity to actually restudy the selected paragraphs before working on the posttest. Results of both experiments indicate that JoLs rather than cognitive load predicted posttest performance. Moreover, students in the drawing condition compared with the control condition exhibited more accurate (relative) monitoring in Experiment 1 in that their JoLs were more strongly related to performance. Moreover, JoLs predicted students' restudy decisions in both experiments; however, this effect was by-and-large independent of whether they had to draw. Overall, results hint towards the potential of drawing to support metacognitive monitoring.     

Emergency management students’ perceptions of the use of WebEOC® to support authentic learning

This study investigates the use of software technology that is used by emergency management professionals to create an authentic learning environment in emergency and disaster management courses in the classroom. Participants were 235 upper-level students enrolled in residential and online emergency and disaster management courses at a mid-sized public university in the southeastern USA. Students participated in simulated disaster exercises that were presented through the software; further, as part of the exercise, students used the software to respond to the simulated disaster. Students then completed a survey to assess their perceptions of whether the exercises and software created an authentic learning environment and enhanced learning.     

Enhancing learning in clinical placements: reflective practice,self-assessment,rubrics and scaffolding

Professional preparatory health programmes generally involve clinical placements with a focus on integration of theory into real life practice. Reflective writing is often included in the assessment requirements for clinical placement courses. However enabling students to engage in deeper levels of reflective writing in action, on action and for action requires careful scaffolding and assessment task design within university clinical placement handbooks. The purpose of this case study was to explore iterative refinement of assessment exercises within clinical placement handbook activities. Specifically, the study examined students’ responses to counselling experiences in authentic pharmacy practice, with comparative analysis undertaken for the various versions of the assessment task. Results showed that provision of iteratively developed guidelines, provided to three different groups of students, to support students in the assessment task, increased the marks achieved for individual components of the assessment. The results provide insight into how the design of these types of assessment exercises can be improved.     

Improving learning skills: a self-help group approach

A self-help group approach was used to enhance medical students' self-directed learning (SDL) skills within an elective course. The SDL task profile envisaged included personal responsibility for, self-direction, and self-monitoring of learning. Reflection and learning partnerships were supported and facilitated by discussion and exercises in a small group context. Self-assessment of SDL tasks, as well as measures of approaches to study using the Approaches to Studying Inventory, were obtained. The results showed increased level of self-efficacy regarding the SDL tasks at the end-of-course. The task self-ratings had significant relationships to measures of deep approach to study. Academic achievement (GPA) was significantly higher for students who participated in the elective experience than for controls. Among the participants, 67% showed enhancement of the SDL task profile. Reasons for lack of improvement are discussed. The findings suggest that the approach used maybenefit most, but not all students under constraining conditions.     

Effects of planning on task load,knowledge, and tool preference: a comparison of two tools

Self-regulated learners are expected to plan their own learning. Because planning is a complex task, it is not self-evident that all learners can perform this task successfully. In this study, we examined the effects of two planning support tools on the quality of created plans, planning behavior, task load, and acquired knowledge. Sixty-five participants each worked with two versions of a planning tool. In one version, learning plans were actively constructed by the learners themselves; the other version provided learners with an adaptable computer-generated plan. The results indicated that the quality of learner-created plans was lower than computer-generated plans. Furthermore, participants reported a higher task load when they constructed the plans by themselves. However, participants gained more structural knowledge about the learning domain when they actively created plans. There was not an apparent preference for one of the tools if participants were to create a plan for someone else. However, if they were to use the plan for their own learning, participants preferred to actively create their own plans.     

Impact of a new integrated medicine program on students’ approaches to learning

This paper presents the results of a study on the impact of a new integrated medical educational design on students’ approaches to learning. Although the new program was based on curriculum features identified in the research literature as likely to promote deeper approaches to learning, the results revealed a more complex response from students. While a proportion of students reacted as expected and changed to deeper approaches, a significant subgroup moved in the opposite direction and adopted more surface approaches. Further analysis revealed that specific features of the new curriculum – integration of content, requirement for both independent and collaborative learning – were likely to polarise students. The findings suggest that shifting students towards deeper approaches to learning may be a more complex task than previously understood. The authors suggest some ways in which such major curriculum change may be moderated so that all learners are more likely to benefit.     

Linking Stereotype Threat and Anxiety

Claude Steele’s stereotype threat hypothesis has attracted significant attention in recent years. This study tested one of the main tenets of his theory—that stereotype threat serves to increase individual anxiety levels, thus hurting performance—using real‐time measures of physiological arousal. Subjects were randomly assigned to either high or low stereotype threat conditions involving a challenging mathematics task while physiological measures of arousal were recorded. Results showed significant physiological reactance (skin conductance, skin temperature, blood pressure) as a function of a stereotype threat manipulation. These findings are consistent with the argument that stereotype threat manipulations either increase or decrease situational‐specific anxiety, and hold significant implications for thinking about fair assessment and testing practices in academic settings.     

Collaborative learning practices: teacher and student perceived obstacles to effective student collaboration

While the educational literature mentions several obstacles affecting the effectiveness of collaborative learning (CL), they have often been investigated through the perceptions of only one actor, either teachers or students. Therefore, some sources of obstacles that teachers and students encounter may not have been revealed. In this study, 19 teachers and 23 students in different disciplines at a pre-service teacher education faculty at a university in Vietnam were interviewed. In total, 47% of the teachers taught science subjects and 53% taught social subjects; 35% of the students majored in science subjects, 57% in social subjects, and 8% in primary education. With regard to study cohorts, 22% of the students were in the first and second year while 78% were in the third and fourth year of their four-year bachelor’s programme. These programmes produce qualified teachers for primary and secondary schools nationwide. Based on grounded theory analysis, four common obstacles to collaboration were identified: students’ lack of collaborative skills, free-riding, competence status, and friendship. Furthermore, the results showed three interrelated antecedents that contribute to these obstacles. Central to the antecedents is the strong focus of the teachers on the cognitive aspects of CL, which led the participating teachers to neglect the collaborative aspects of CL. These antecedents were demonstrated in the ways teachers set CL goals, provided instruction, and assessed student collaboration. This study may be useful for educators, designers, and researchers to foster the quality of student collaboration.     

Evaluation of a surfing programme designed to increase personal well-being and connectedness to the natural environment among ‘at risk’ young people

Outdoor activities can be an important complement to classroom learning, especially for children/young people excluded, or at risk of exclusion, from mainstream schooling. The current research explored the impact of a 12-week surfing programme among such a group in the UK. Pre-post data on physiological health (heart rate (HR)/blood pressure), self-reported well-being (life and domain satisfaction), connectedness (e.g. to nature, school), environmental awareness (e.g. role of sand dunes) and teacher evaluations (e.g. behaviour) were collected. Results found significant drops in HR (suggesting improved fitness), increased satisfaction with appearance, more positive attitudes towards school and friendships, greater environmental awareness and more positive teacher evaluations, post-intervention. A lack of findings in other domains suggests these results were not due to participants simply conforming to demand characteristics. Overall, the results suggest that surfing interventions could have important benefits for vulnerable young people who struggle with mainstream schooling. The need for future research using control groups and longer term follow-up is discussed.
