Test Anxiety and Working Memory

In the present study, information processing of test anxiety is explained within the framework of the ACT* model. The author used the speed-accuracy tradeoff method to investigate the effect of test anxiety on each subsystem of working memory. The sample was made up of 119 college students enrolled in an educational psychology course. Test anxiety affected performance on the verbal-analogies task but not on the rhyming-judgment and visual-spatial tasks. The participants' subvocalization of the rhyming words may have drawn attention to the task itself and preempted the effect of test anxiety on task performance. Also, the activation processes for the visual-spatial tasks may have occurred in a different dimension or separate from the verbal processes of test anxiety.     

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.     

Implications of task structure on self‐regulated learning and achievement

School tasks interact with student motivation, cognition, and instruction to influence learning and achievement. Heeding calls for additional research linking motivational and cognitive factors in learning and instruction on specific tasks within authentic classroom settings we quantitatively and qualitatively track 90 tenth‐grade science students’ motivation, reported use of learning strategies, achievement, calibration, and task perceptions as they engage in a well‐structured task (WST) and an ill‐structured task (IST). Students achieved higher grades on, and reported more ease and value for, the WST whereas they utilised critical thinking and peer learning strategies more on the IST. Lower academic achievers calibrated their achievement less accurately on each task and experienced lower grades, interest, ease, and management capability on the IST. Conversely, higher academic achieving students reported more self‐efficacy and effort regulation and lower anxiety and elaboration on the IST. Motivation – notably less intrinsic goal orientation in low academic achievers and higher task value and self‐efficacy – predicted performance on the IST. The structure of tasks may provide prompts that illicit unique self‐regulated learning responses in students.     

Interleaved practice in multi-dimensional learning tasks: Which dimension should we interleave?

Research shows that multiple representations can enhance student learning. Many curricula use multiple representations across multiple task types. The temporal sequence of representations and task types is likely to impact student learning. Research on contextual interference shows that interleaving learning tasks leads to better learning results than blocked practice, but this research has not investigated whether it matters on which dimension we interleave learning tasks. Many educational materials include multiple task types and multiple representations. Should we interleave representations or task types? We conducted a classroom experiment to investigate the effects of interleaving task types (while blocking representations) and interleaving representations (while blocking task types). The participants (158 5th- and 6th-graders) worked with a corresponding version of an intelligent tutoring system for fractions. Our results show an advantage for interleaving task types over interleaving representations. These results extend prior work on contextual interference by showing that this effect is sensitive to the dimension being interleaved. We also extend the literature on learning with multiple representations by investigating the effect of interleaved practice with different representations. The results provide guidance to designers of complex curricula.     

Finnish students’ reasons for their achievement in classroom activities: focus on features that support self-regulated learning

The aim of this study was to investigate how finnish students explain factors that contribute to their achievement in classroom learning activities and whether these factors are related to support of self-regulated learning (SRL) in classroom. Over seven weeks, 24 primary school students were videotaped during their typical classroom activities in 28 lessons to capture moments when they succeeded in learning tasks. From the video observations, 62 episodes were edited and used in stimulated recall interviews in which students were asked to report the reasons they related to their achievement in learning situations. Data-driven content analysis was used to analyse the open-ended interview data. The video observation data were analysed and sorted into theory-driven categories in order to find out how SRL was supported in classrooms. The results showed that students describe achievement through the actions that they took in the learning situations, such as being able accomplish the task. The reasons given for their achievement dealt with ability to accomplish the tasks or doing academic activities in order to achieve in the task. Furthermore, the students recognised classroom activities that support SRL, acknowledging their contribution to their achievement, mostly through the support that they received from their teachers and peers.     

Comparing Class- and Task-Level Measures of Achievement Goals

Models of achievement goals suggest that different tasks and contexts influence the goals students adopt at a given time. However, many studies of achievement goals rely on measures assessed at the class level, analyze results with a variable-centered approach, and employ self-report questionnaires, which may reduce understanding of the contextual factors that arise as students interact with tasks. We compared a behavioral, task-level measure of middle school students' achievement goals to a self-reported, class-level measure and analyzed both measures' relations to task performance and quarterly grades using both variable-centered and person-centered approaches. Task-level goals predicted task performance but not quarterly grades, while class-level goals predicted grades but not task performance. The two measures of achievement goals were not related. This work demonstrates the importance of measuring goals at multiple levels and suggests opportunities for changing students' behaviors and achievement through motivation at the task level.

Achievement,underachievement and cortical activation: a comparative EEG study of adolescents of average and above‐average intelligence

In this study the neural efficiency phenomenon (more efficient brain function in brighter as compared to less intelligent individuals) was investigated regarding differences in intelligence (average vs. above‐average intelligence) and scholastic achievement (achievers vs. underachievers). The cortical activation (assessed by event‐related desynchronisation in the EEG) of 31 male adolescents was measured while performing a verbal and figural version of Posner's letter matching task and two creativity tasks. During the figural Posner task, average intelligent underachievers showed higher frontal activation than similarly intelligent achievers and brighter underachievers, whereas average intelligent achievers showed higher posterior activation. During one creativity task underachievers were frontally less activated than achievers. The results provide first evidence that different achievement levels are also reflected in different levels of cortical activation.     

First-year students’ appraisal of assessment tasks: implications for efficacy,engagement and performance

This study investigated students’ appraisals of assessment tasks and the impact of this on both their task-related efficacy and engagement and subsequent task performance. Two hundred and fifty-seven first-year students rated their experience of an assessment task (essay, oral presentation, laboratory report or exam) that they had previously completed. First-year students evaluated these assessment tasks in terms of two general factors: the motivational value of the task and its manageability. Students’ evaluations were consistent across a range of characteristics and level of academic achievement. Students’ evaluations of motivational value generally predict their engagement and their evaluations of task manageability generally predict their sense of task efficacy. Engagement was a significant predictor of task performance (viz. actual mark) for exam and laboratory report tasks but not for essay-based tasks. Findings are discussed in terms of the implications for assessment design and management.

Grammaticality judgments and reading skill in grade 2

Do the language problems associated with reading disability extend to sentence-level knowledge? If so, how should these problems be characterized? In this study, second graders were presented with two different oral syntactic tasks, equivalent in grammatical complexity, but varying in the actual task demands placed upon the reader. In theJudgment task, subjects were asked to distinguish between grammatical and ungrammatical sentences; in theCorrection task, subjects were asked to remedy violations of grammaticality. Performance on these sentence-level tasks was, in turn, examined in relation to reading scores, memory span, and metaphonological skill. The Judgment task revealed a wide range of ability among second-graders, and scores were systematically affected by the syntactic nature of the violation. However, performance on Judgment was not associated with reading ability or metaphonological skill, and scores were minimally affected by short-term memory factors. Mean scores on the Correction task were comparable to those achieved in the Judgment task and were also systematically affected by syntactic factors. However, performance on Correction was strongly associated with reading ability and metaphonological skill, and was greatly affected by short-term memory factors. These results suggest that reading disability does not reflect problems in basic syntactic knowledge. Instead, sentence-level problems that have been observed in less-skilled readers may be caused by the nonlinguistic processing demands of the syntactic measures typically employed.

The impact of criteria-referenced formative assessment on fifth-grade students’ theater arts achievement

The purpose of this study was to examine the effects of criteria-referenced formative assessment (CRFA) on students’ achievement in theater arts. The role of type of task in differentiating the treatment-achievement relationship was explored. The analytical sample included 520 fifth-grade students from 13 schools in New York City. Schools were randomly assigned to the treatment or control group. Selection bias in treatment assignment at student level was adjusted with propensity score analysis. CRFA had a positive effect on students’ achievement on performance tasks (d = 0.25), but no significant effect on students’ performance on the analytical constructed response tasks or the theater vocabulary multiple-choice items.     

The effects of a structured learning sequence on Children's correlative thinking about biological phenomena

The purpose of this study was to determine if the achievement on correlational thinking tasks could be enhanced by a set of structured training exercises. The exercises were based on Piaget's analysis of the development of correlative thinking in adolescents. The achievement of the ninth grade students was greater than the achievement of the fifth and seventh grade students. However, some of the ninth grade students exhibited difficulty with the equivalence and reciprocal exclusion operations that were necessary for the solution of the correlation tasks. The results of the study suggest that the ninth grade students may be in the transition zone for this particular operation.     

Understanding STEM-focused high school students’ perceptions of task importance: The role of “standing out” and “fitting in” in mathematics class

One theoretical extension of Optimal Distinctiveness Theory (ODT;  and ) is that individuals will work toward the satisfaction of their own social identity needs for differentiation (standing out) and assimilation (fitting in). Because these needs serve as driving forces behind the attitudes people adopt, and the behaviors they enact, the motivational properties of these needs are likely to be manifest in achievement contexts. Bridging ODT and Expectancy-Value Theory, this article examines the prediction that academic tasks are seen by students as more important when they contribute to students’ ability to stand out (task differentiation) from and fit in (task assimilation) with their classmates. This prediction was supported among an ethnically diverse sample of STEM-focused high school students who rated the importance of 18 mathematics-related academic tasks. Additional analyses demonstrated that the association between task assimilation and task importance was stronger for students who perceived their academic learning environment to be performance-focused (performance goal structure). There also was a significant interaction between task differentiation and task assimilation, such that the association between task assimilation and task importance attenuated at higher levels of task differentiation. The present study is one of the few investigations to assess how students’ valuing within a single academic domain might fluctuate from one academic task to the next (e.g., taking notes versus working out problems on the board). The Discussion addresses the theoretical and practical significance of acknowledging differentiation and assimilation as vehicles for motivating students in the classroom.     

Pursuing a Multidimensional View of Transfer

Training researchers and practitioners have typically focused their attention on one type of transfer, the transfer of tasks that require trainees to learn and apply a prescribed standard procedure. Further, researchers and practitioners have examined this type of transfer in situations where supervisors hold trainees accountable for applying the trained knowledge and skill, Performance professionals have developed theoretical frameworks, training principles, and training guidelines to improve transfer based on this conception of transfer. In contrast, this paper presents a multidimensional perspective to training transfer. One dimension concerns task adaptability-a continuum from relatively closed tasks, where task steps are highly prescribed, to relatively open tasks, where the task steps can be adapted to varying circumstances of the job. The other dimension concerns worker autonomy-a continuum from heavily supervised to highly independent work. Based on this expanded perspective of transfer, for each combination of variable, we offer principles for effective transfer as well as specific problems which must be solved to achieve the best results. We also provide suggestions for evaluating training success and derive research propositions that deserve attention.     

Task-Specific Self-Evaluation as a Measure of Achievement Motivation

The validity of an internalized self-reinforcement paradigm as a model of achievement motivation was investigated with a sample of 230 ninth grade black pupils of an inner-city public school located in a midwestern metropolitan area. If achievement behavior is controlled and sustained by covert internal evaluations of performance, then students who more frequently report positive self-evaluations during some specific school-like task may be predicted to: a.) have higher grade point averages than students who less frequently report self-evaluations of task performance; b.) have lower rates of absence from school than students who less frequently report positive self-evaluations of task performance; c.) have greater levels of expected task performance than students who less frequently report positive self-evaluations of performance; d.) have greater expectations that they will be able to positively evaluate themselves for task performance than students who less frequently report positive self-evaluations; e.) have greater congruence between self-established standards and actual performance. Analyzed by 2-way analysis of variance (self-evaluation x sex), the data supported each of the predictions. The results were interpreted to support the conception of self-evaluations of task performance as a model of achievement motivation. In the absence of external rewards, the student sustains his academic behavior by the quality of the covert self-evaluations of his own performance. The positive or negative value of these evaluations depends on self-established standards. Students who tend to evaluate themselves negatively may do so as a function of arbitrarily high standards. Their performance on academic tasks will be less well sustained and their functioning at consequently lowered levels of achievement. The paper-and-pencil self-reports used in the study yielded results comparable to the elaborate laboratory instrumentation of previous studies.     

Child effortful control,teacher–student relationships,and achievement in academically at-risk children: Additive and interactive effects

The joint contributions of child effortful control (using inhibitory control and task accuracy as behavioral indices) and positive teacher–student relationships at first grade on reading and mathematics achievement at second grade were examined in 761 children who were predominantly from low-income and ethnic minority backgrounds and assessed to be academically at-risk at entry to first grade. Analyses accounted for clustering effects, covariates, baselines of effortful control measures, and prior levels of achievement. Even with such conservative statistical controls, interactive effects were found for task accuracy and positive teacher–student relationships on future achievement. Results suggest that task accuracy served as a protective factor so that children with high task accuracy performed well academically despite not having positive teacher–student relationships. Further, positive teacher–student relationships served as a compensatory factor so that children with low task accuracy performed just as well as those with high task accuracy if they were paired with a positive and supportive teacher. Importantly, results indicate that the influence of positive teacher–student relationships on future achievement was most pronounced for students with low effortful control on tasks that require fine motor skills, accuracy, and attention-related skills. Study results have implications for narrowing achievement disparities for academically at-risk children.     

Sampling Variability of Performance Assessments

In this article, performance assessments are cast within a sampling framework. More specifically, a performance assessment is viewed as a sample of student performance drawn from a complex universe defined by a combination of all possible tasks, occasions, raters, and measurement methods. Using generalizability theory, we present evidence bearing on the generalizability and convergent validity of performance assessments sampled from a range of measurement facets and measurement methods. Results at both the individual and school level indicate that task-sampling variability is the major source ofmeasurment error. Large numbers of tasks are needed to get a reliable measure of mathematics and science achievement at the elementary level. With respect to convergent validity, results suggest that methods do not converge. Students' performance scores, then, are dependent on both the task and method sampled.     

Verbal predictive ability and performance on selected science process tasks

This study investigated the relationships between verbal predictive ability, as measured by a word deletion technique called the “cloze procedure,” and performance on selected science process tasks. The results of the study confirmed a highly significant relationship between the two variables, but failed to show that verbal predictive ability is a significantly better predictor of process task achievement than is a standardized test of verbal ability. It is suggested that the results could be utilized in the design of teacher education programs in science if these programs focus primarily on the processes of science.
