Learning to use functional rules in inference tasks

Abstract.— Earlier studies have established that subjects perform less well in inference tasks with nonlinear rules than in tasks with linear rules, and that one source of the lower level of performance in nonlinear tasks is that the subjects cannot utilize a nonlinear rule as well as they utilize a linear rule. The three experiments in this paper investigate whether utilization of a nonlinear rule can be improved by training. The results show that there is some improvement with training, but the improvement could not be attributed to feedback, or to the learning of specific cue and criterion values. Cognitive feedback did not produce higher performance than ordinary outcome feedback.     

Anxiety,Learning, and Instruction (Book)

When witnesses at a trial offer testimony that is vivid, it may be more persuasive than the same testimony offered in a pallid manner. In this paper we elucidate three categories of variables (inferential, attentional/memorial, and affective) that are likely to mediate the effects of the vividness of testimony on jury judgments. These variables are then used to explain discrepant findings among mock juror experiments investigating vividness effects. Finally, we discuss the implications of vividness effects for the legal system.     

Developing a Learning Progression for Curriculum,Instruction, and Student Learning: An Example from Mathematics Education

Learning progressions have been demarcated by some for science education, or only concerned with levels of sophistication in student thinking as determined by logical analyses of the discipline. We take the stance that learning progressions can be leveraged in mathematics education as a form of curriculum research that advances a linked understanding of students learning over time through careful articulation of a curricular framework and progression, instructional sequence, assessments, and levels of sophistication in student learning. Under this broadened conceptualization, we advance a methodology for developing and validating learning progressions, and advance several design considerations that can guide research concerned with engendering forms of mathematics learning, and curricular and instructional support for that learning. We advance a two-phase methodology of (a) research and development, and (b) testing and revision. Each phase involves iterative cycles of design and experimentation with the aim of developing a validated learning progression. In particular, we gathered empirical data to revise our hypothesized curricular framework and progression and to measure change in students. thinking over time as a means to validate both the effectiveness of our instructional sequence and of the assessments designed to capture learning. We use the context of early algebra to exemplify our approach to learning progressions in mathematics education with a focus on the concept of mathematical equivalence across Grades 3-5. The domain of work on research on learning over time is evolving; our work contributes a broadened role for learning progressions work in mathematics education research and practice.     

Dyad Practice Impacts Self-Directed Practice Behaviors and Motor Learning Outcomes in a Contextual Interference Paradigm

We studied dyad practice to determine whether and how alternating practice blocks with a partner impacts self-directed practice scheduling, learning, and perceptions of practice. Participants were assigned to be Partner 1 (P1) or 2 (P2). P1s had a blocked, random, or self-directed schedule, while all P2s self-directed practice of 3, differently-timed keystroke-sequences. P2s showed both own error-dependent practice (switching sequences following better performance) and partner-dependent practice, with the partner's schedule impacting sequence selection and switching frequency. A partner's schedule also impacted learning. Random practice resulted in better timing accuracy than blocked practice for both partners in an immediate and delayed retention test. These data give evidence that self-directed practice behaviors and learning outcomes are modulated by a partner's practice schedule.     

Individualized Challenge Point Practice as a Method to Aid Motor Sequence Learning

We conducted two studies to investigate if and how: (1) the rate of skill acquisition was related to motor performance at retention of a serial RT task (Study 1); and (2) whether rate of skill acquisition and baseline performance could be used to design schedules of practice related to contextual interference (CI) to enhance motor learning (Study 2). In Study 1, a slower rate of skill acquisition of repeating sequences in practice was related to faster response times at retention. Based on performance in Study 1, three levels of individualized CI were created for Study 2. Compared to low and moderate levels of CI, the higher CI practice condition led to faster response times in retention. We conclude that an individualized ‘challenge point’, which generates high CI enhances motor learning by optimizing challenge.     

Improving Graduate Theological Instruction: Using Classroom Assessment Techniques to Connect Teaching and Learning

Classroom Assessment Techniques (CATs) offer immediate, relevant feedback to professors on the teaching process as well as feedback to students on the learning process. While Classroom Assessment Techniques have been introduced, studied and analyzed in undergraduate education, application to graduate theological education has not been advanced. The author describes a recent research project that discerned faculty attitudes toward the implementation of Classroom Assessment Techniques in a seminary setting in hopes that more effective faculty development programs can be designed by implementing CATs.

Using Detect, Practice, and Repair (DPR) to Differentiate and Individualize Math Fact Instruction in a Class-Wide Setting

A multiple baseline design was used across probe sets to evaluate the effect of detect, practice, and repair (DPR) on the math fact fluency rates of a third-grade class. DPR was applied with a large group (n = 11) selected from an intact class (n = 17) in a manner that allowed each student to work on specific problems from a specific basic fact operation (i.e., subtraction, multiplication, or division) based on a daily assessment of their instructional needs. Prior to the implementation of DPR, students were computing an average of 18.4 digits correct per minute (DCPM). After using DPR for 11 sessions, students were computing an average of 31.2 DCPM. This 12.8 DCPM increase over 36 problems required approximately 132 min (12 min per session). Discussion focuses on the need for and challenges associated with developing intervention strategies and procedures that efficiently increase student skills at the class-wide level, with an emphasis on simultaneously meeting the needs of both high and low achievers by differentiating instruction.     

Peer Tutoring: Teaching Students with Learning Disabilities to Deliver Time Delay Instruction

This study evaluated the effectiveness of a peer-mediated constant time delay procedure for teaching written spelling to fourth- and fifth-grade students identified as learning disabled. The six peer tutors (each with learning disabilities) taught each other to produce the written spelling for 15 five- to eight-letter words using a 3-s delay and a visual model prompt. A multiple probe design across behaviors (word sets) was used to evaluate the procedure. Data were collected on the number of sessions to criterion, trials to criterion, number and percent of errors, and direct instructional time. The classroom teacher prepared students to serve as tutors using a describe-model-guided practice-feedback sequence. Pre- and post-measures were conducted of generalization of the tutoring procedure as well as observational learning by the tutors. Results indicated that (a) peer tutors reliably implemented the time delay procedure, and (b) the tutor-implemented time delay procedure was effective in teaching written spelling to students identified as learning disabled.     

Mainstreams and Perspectives in Research on Learning (Mathematics) From Instruction

Le domaine de l’enseignement et de l’apprentissage des mathématiques est un exemple des plus représentatives de l’orientation des recherches sur l’apprentissage et l’instruction dans les différentes matières. Au cours du dernier quart de siècle écoulé, ce champ de questionnement a produit nombre d’investigations qui résultent d’une conception de l’apprentissage des mathématiques comme construction sociale de la signification et de la comprehension basée sur la modélisation de la réalité. Dans cet article, quelques tendances majeures et perspectives de recherche s.0s principalement aux Etats‐Unis et en Europe. Il y sera montré que d’une part, les investigations empiriques ont déjà produit des blocs de construction pour l’élaboration d’une théorie de l’apprentissage des mathématiques à partir d’instructions mais que, d’autre part, des questions et des problèmes majeurs requièrent d’être démêlés par la poursuite d’investigations. Ceci y sera documenté de façon exemplaire en utilisant comme cadre de référence quatre composants principaux d’une théorie de l’apprentissage des mathématiques à partir d’instructions: une théorie de l’expertise visant à analyser des compétences dans un domaine; une théorie de l’acquisition tendant à comprendre et expliquer les processus d’apprentissage qui conduisent à la réalisation de compétences; une théorie de l’intervention, focalisée sur la conception d’environnements enseignement‐apprentissage puissants pour provoquer ces processus d’acquisition; et une théorie de l’évaluation s’adressant au développement de méthodes et techniques pour la construction et l’application d’outils et instruments d’évaluation. The domain of mathematics learning and teaching is one of the most representative examples of the subject‐matter orientation in research on learning and instruction. During the last quarter of the past century this field of inquiry has produced a vast body of investigations, resulting in an enriched conception of mathematics learning as involving the (social) construction of meaning and understanding based on modeling of reality. In this article some of the main trends and perspectives in the field of research on mathematics learning and instruction are discussed, and illustrated with examples of empirical research, mainly carried out in Europe and the United States. It will be shown that, on the one hand, the available empirical investigations have already yielded substantial building blocks for the elaboration of a theory of mathematics learning from instruction, but that, on the other hand, major issues and problems need to be unravelled by continued inquiry. This will be documented in an exemplary way, using as a frame of reference four main components of a theory of learning mathematics from instruction: a theory of expertise, aiming at analysing competence in a domain; a theory of acquisition, attempting to understand and explain the processes of learning that are conducive to the attainment of competence; a theory of intervention, focusing on the design of powerful teaching–learning environments for eliciting those acquisition processes; and a theory of assessment, addressing the development of methods and techniques for the construction and application of assessment tools and instruments.     

The Reciprocal Transfer of Learning from Journals to Practice

A strong case can be made for the reciprocal transfer of learning between the journals and practice, as well as for blurring the distinction between the science and practice of I/O psychology. This is because journals consistently provide answers for practice, and the implementation of the answers provides a basis for publication and subsequent research. The author's research and practice in the areas of employee motivation, performance appraisal, training, and personnel selection are used in support of these arguments.     

Learning to Notice Mathematics Instruction: Using Video to Develop Preservice Teachers' Vision of Ambitious Pedagogy

Video is used extensively in teacher preparation, raising questions about what and how preservice teachers learn through video observation and analysis. We investigate the development of candidates' noticing of ambitious mathematics pedagogy in the context of a video-based course designed to cultivate ways of seeing and interpreting classroom interactions. Qualitative analysis of candidates' observations of teaching at the beginning and end of the course generated a framework of practices and associated approaches for noticing instructional interactions. The 3 practices include attending to features of instruction, elaborating on observations, and integrating observations to reason about instruction. Findings reveal that variations in candidates' noticing was tied to their attention to the details of the features of ambitious pedagogy and to the extent to which they integrated observations to examine the relation between student thinking, teaching practice, and mathematical content.     

学习方式的变革:提取促进学习

提取练习效应是指在学习与最终测验之间,等长时间的提取练习与重复学习相比,前者更能促进长时记忆的保持,也称为测试效应。大量研究表明提取测试是一种高效的学习策略,师生却对此认识不足,认为测试只是检测学习效果的评估工具,并不能改变或促进学习。本文主要从提取练习促进学习的认知神经加工机制、提取练习在实践应用中的特点、提高提取练习效应的方法及其在教学实践中的局限四方面梳理了相关研究,为提取练习广泛应用于教学实践提供支持,同时也为师生正确高效利用这一策略提供了参考,使学生获得更高效和持久的学习。
