Load reduction instruction in mathematics and English classrooms: A multilevel study of student and teacher reports

Load reduction instruction (LRI) is a practical instructional framework aimed at managing the cognitive demands experienced by students as they learn. LRI comprises five key instructional principles: (1) difficulty reduction during initial learning, as appropriate to students’ prior learning, (2) support and scaffolding, (3) structured practice, (4) feedback-feedforward, and (5) guided independent application. The present investigation explored student- and teacher-reports of LRI in both mathematics and English. The Load Reduction Instruction Scale – Short was administered to 1773 students and their teachers in 93 mathematics classrooms and 94 English classrooms. Multilevel (Level 1 student; Level 2 classroom) confirmatory factor analysis (MCFA) supported a Level 1 student LRI factor and a Level 2 class-average LRI factor in each of mathematics and English. However, two LRI factors emerged for teachers in each of mathematics and English: one factor related to Principle 1 (difficulty reduction) and one factor related to Principles 2–5 (scaffolding to autonomy). Follow-up multilevel structural equation modeling (MSEM) revealed that teachers adjusted their application of LRI Principle 1 (but not Principles 2–5) as a function of class-average prior learning (lower prior learning was associated with greater application of Principle 1). MCFA also showed that correlations between student- and teacher-reported LRI were low. Follow-up MSEM revealed that student- and teacher-reports of LRI uniquely predicted students’ effort and achievement—suggesting that students and teachers provide distinct insights into instruction (hence the low correlation between them) and highlighting the important role of both informants in capturing a comprehensive perspective on instruction in the classroom.     

The effect of blended instruction on accelerated learning

While online instructional technologies are becoming more popular in higher education, educators’ opinions about online learning tend to be generally negative. Furthermore, many studies have failed to systematically examine the features that distinguish one instructional mode from another, which weakens possible explanations for why online instructional technology can be beneficial. The current study isolates three benefits of the authors’ particular online instructional technology: (1) providing flexibility in how students learn, (2) offering immediate and targeted feedback and (3) increasing student participation and engagement with instructional material. Maximum benefits were observed when students used the online instructional technology to prepare for their face-to-face class – that is, students with this blended instruction learned twice as much content in the same amount of time in comparison to students with face-to-face instruction alone, without creating an atypically high workload.     

Reducing the prior-knowledge achievement gap by using technology-assisted guided learning in an undergraduate chemistry course

There have been many practical obstacles for teachers to implement evidence-based educational technology, especially in STEM classrooms. By implementing learning principles related to Cognitive Load Theory, we developed an innovative Technology-Assisted Guided Learning (TAGL) approach and its web-based instructional tool, combining expertise from educational research and best teaching practices to enhance guided student-centered learning in chemistry. A total of 185 community college students were randomly assigned to learn stoichiometry through either TAGL or one of two active control interventions, traditional direct instruction and Khan Academy, a widely used web learning platform. We found that the TAGL group significantly outperformed both active control groups immediately after instruction, and furthermore, despite the fact that all groups received additional instruction in stoichiometry, the beneficial effects of TAGL compared to the control groups were maintained a month later. Notably, TAGL was able to eliminate the achievement gap between students with low prior knowledge and students with high prior knowledge. Furthermore, prior-knowledge activation was found to be especially beneficial for students with low prior knowledge. Our work contributes to existing research in learning theories and provides new insight toward the development of more effective and adaptive instructional designs. By translating research into practice, this study demonstrates the great potential of using innovative computer-based technology to improve student learning for all.     

教学策略、方法与结构——以知识与技能教学为例

教学策略是使学生掌握学习结果并形成互动的主要媒介。教学方法是教学策略的一个组成要素,也是传递学习内容并提供学习指导以保证学生掌握所学知识技能的过程。教学策略和方法本身很难说有什么好坏优劣之分,只不过不同的人适合不同的策略,而选择合适的教学策略的目的就是为了充分发挥其功效而不至于浪费或误用。课堂教学结构是指在教学中发挥特定功能的可资辨别的要素。它是教学过程中的基本构成板块,也是充分发挥教学功能,提高教学效率所必需的。课堂教学结构中的核心成分包括:明确教学目标,导入新课,聚焦核心知识点,提供举例或说明,开展练习和给予反馈。各类教学策略或者方法都可以在课堂教学结构中得到运用。

Process-oriented instruction in learning and thinking strategies

Process-oriented instruction is defined as instruction aimed at teaching thinking strategies and domain-specific knowledge in coherence. This new conception of instruction is derived from psychological research on the way students learn and on the interplay between self-regulation and external regulation of learning. In the research reported here the learning effects of a process-oriented instructional program for university students were empirically studied. The instructional program consisted of a diagnostic learning style instrument, a learning guide and tutorials. The results showed that the majority of students reported significant general, knowledge, insight and application learning effects. The program effects were typified more by integrating and making usable metacognitive knowledge already present, than by increasing knowledge about new subjects. Evidence for transfer effects was obtained because participants in the program scored better than non-participants on two exams of another course. The learning effects were higher than the effects of an preliminary version of the program implemented with students from an open university. These results support the importance of the process-oriented instructional model. The linking of a thorough diagnosis of personal learning styles to individually tailored instructional measures, turned out to be a powerful way to activate students to reflect on their learning and to develop their mental models of learning.     

Impact of simulator-based instruction on diagramming in geometrical optics by introductory physics students

We examine the conceptual development resulting from an instructional experiment with an interactive learning environment in geometrical optics for introductory high school physics. How did teaching-learning processes come to change the ways in which students depicted various everyday optical situations in paper and pencil graphical representations? We view conceptual development as a process resulting in part from increasingly aligning one's practices to a target community by means of participating in a community of practice that uses the target concepts. For formal science learning, this participation requires changes in concepts, epistemological attitude, and in the development and use of representational tools, including diagrams and technical language, as a means of communication. Results of our instructional experiment indicated that students went through major conceptual developments as reflected in the diagrams they constructed and supported by other representational tools and as judged in terms of several perspectives: in identifying the formation of shadows and images, in recognizing the eye as a participating factpr in the optical system, and in changing the types of justifications they provided in their optical reasoning from presuppositional to causal.     

Integrating e-learning into the Direct-instruction Model to enhance the effectiveness of critical-thinking instruction

The Direct-instruction Model favors the use of teacher explanations and modeling combined with student practice and feedback to teach thinking skills. Using this paradigm, this study incorporates e-learning during an 18-week experimental instruction period that includes 48 preservice teachers. The instructional design in this study emphasizes scaffolding, observational learning, mastery of critical-thinking skills, guided practices, cooperative learning, providing feedback, self-reflection, online discussions, and active participation in an online learning community. This study employs 2 critical-thinking tests, 2 inventories, and 1 open-ended reflection questionnaire; and students’ scores on the pretest and posttest are compared via the Repeated Measure Analysis of Variance. The primary findings are as follows: (a) all participants preferred the instructional design in this study; (b) the experimental instruction effectively improved the preservice teachers’ critical-thinking ability as well as their professional knowledge and personal teaching efficacy concerning critical-thinking instruction; (c) the mechanisms contributing to the effectiveness of the experimental instruction mainly included discussing and sharing, observational learning, self-reflection, guided practice, and the learning community.     

Engaging in vocabulary learning in science: the promise of multimodal instruction

To a science ‘outsider’, science language often appears unnecessarily technical and dense. However, scientific language is typically used with the goal of being concise and precise, which allows those who regularly participate in scientific discourse communities to learn from each other and build upon existing scientific knowledge. One essential component of science language is the academic vocabulary that characterises it. This mixed-methods study investigates middle school students’ (N?=?59) growth in academic vocabulary as it relates to their teacher’s instructional practices that supported academic language development. Students made significant gains in their production of general academic words, t(57)?=?2.32, p?=?.024 and of discipline-specific science words, t(57)?=?3.01, p?=?.004 in science writing. Results from the qualitative strand of this inquiry contextualised the students’ learning of academic vocabulary as it relates to their teacher’s instructional practices and intentions as well as the students’ perceptions of their learning environment. These qualitative findings reveal that both the students and their teacher articulated that the teacher’s intentional use of resources supported students’ academic vocabulary growth. Implications for research and instruction with science language are shared.     

Towards a framework for effective instructional explanations in science teaching

ABSTRACT

Instructional explanations have sometimes been described as an ineffective way to teach science, representing a transmissive view of learning. However, science teachers frequently provide instructional explanations, and students also offer them in cooperative learning. Contrary to the transmissive view regarding explanation, studies suggest that instructional explanations might be successful if they are based on an interaction between explainers and explainees, including the diagnosis of understanding and adaptation to the explainee’s needs. The present article has three goals: (1) It will propose a framework for potentially effective instructional explanations, presenting five core ideas of what constitutes effective instructional explanations and two concerning how they should be implemented into science teaching. (2) To justify the framework, the article will review studies on the effectiveness of instructional explanations. It will identify factors that have been researched for their impact on the effectiveness of instructional explanations and discuss them for their applicability to science teaching. (3) This article will connect the research on instructional explanations with the idea of basic dimensions of instructional quality in science. It will discuss the core ideas as particular expressions of the basic dimensions of instructional quality, specifically ‘cognitive activation’ and ‘constructive support’.     

Is there a role for direct instruction in problem-based learning? Comparing student-constructed versus integrated model answers

Problem-based learning (PBL) requires students to formulate learning issues that need to be answered by studying multiple literature resources. Advocates of high instructional guidance argue that this is too cognitively demanding for students and ineffective for learning. Therefore, we examined the effects of studying an integrated model answer in the self-study phase in PBL. Participants (N = 62) engaged in a simulated group discussion, ending with the establishment of learning issues. Then they either studied integrated model answers to the learning issues, or undertook a standard PBL self-study phase in which students needed to construct their own answers based on multiple literature resources. Higher learning outcomes were obtained for the participants who studied integrated model answers when compared to the participants who constructed their own answers. These higher learning outcomes were obtained with lower investment of self-study and equal investment of mental effort during learning.     

The effects of metacognitive instruction embedded within an asynchronous learning network on scientific inquiry skills

The study is aimed at investigating the effects of four learning methods on students’ scientific inquiry skills. The four learning methods are: (a) metacognitive‐guided inquiry within asynchronous learning networked technology (MINT); (b) an asynchronous learning network (ALN) with no metacognitive guidance; (c) metacognitive‐guided inquiry embedded within face‐to‐face (F2F) interaction; and (d) F2F interaction with no metacognitive guidance. The study examined general scientific ability and domain‐specific inquiry skills in microbiology. Participants were 407 10th‐grade students (15 years old). The MINT research group significantly outperformed all other research groups, and F2F (group d) acquired the lowest mean scores. No significant differences were found between research groups (b) and (c). MINT makes significant contributions to students’ achievements in designing experiments and drawing conclusions. The novel use of metacognitive training within an ALN environment demonstrates the advantage of enhancing the effects of ALN on students’ achievements in science.

Item difficulty in the evaluation of computer-based instruction: an example from neuroanatomy

This article reports large item effects in a study of computer-based learning of neuroanatomy. Outcome measures of the efficiency of learning, transfer of learning, and generalization of knowledge diverged by a wide margin across test items, with certain sets of items emerging as particularly difficult to master. In addition, the outcomes of comparisons between instructional methods changed with the difficulty of the items to be learned. More challenging items better differentiated between instructional methods. This set of results is important for two reasons. First, it suggests that instruction may be more efficient if sets of consistently difficult items are the targets of instructional methods particularly suited to them. Second, there is wide variation in the published literature regarding the outcomes of empirical evaluations of computer-based instruction. As a consequence, many questions arise as to the factors that may affect such evaluations. The present article demonstrates that the level of challenge in the material that is presented to learners is an important factor to consider in the evaluation of a computer-based instructional system.     

The impact of technology enhanced science instruction on pedagogical beliefs and practices

The paper presents a qualitative case study of a Technology Enhanced Instruction (TEI) model called Technology Enhanced Secondary Science Instruction (TESSI). The implementation of TEI in TESSI classrooms resulted in significant changes in the educational beliefs, and the teaching and learning practices of those involved: a) classroom structures were modified to emphasize guided, self-directed learning; b) views of learning were transformed to regard skills such as time management, goal setting, self monitoring, and problem solving to be as significant as science knowledge; and c) teachers' roles were changed from transmitters of knowledge to facilitators of learning. These changes are illustrated through reflections by the teachers, students, administrators and researchers associated with the Project. TESSI resulted in a significant increase in enrollment and achievement as measured by government exams.     

Implementing process-based instruction in regular university teaching: Conceptual,methodological and practical issues

This paper reports an experimental field study aimed at examining whether a process-oriented form of instruction (combining program planning and interactive teaching) which produced outstanding results when implemented by a tutor/researcher (see Volet, 1991) could be used successfully by regular university tutors given detailed guidelines but minimal training. A second aim of the study was to establish the respective contribution of the two sub-components of the instructional package. The results of the study were inconclusive and raise a number of conceptual, methodological and practical issues. As in the initial study, experimental students were more satisfied with their learning and for those who had the choice, more inclined to undertake further studies in computing but the intervention did not affect students’ achievement. The results of the study are discussed in relation to the earlier work, and suggestions are made for bridging the gap between educational research and educational practice in higher education.     

The effect of different chunking strategies in complementing animated instruction

The purpose of this exploratory and small‐scale study was to examine the instructional effects of different chunking strategies used to complement animated instruction in terms of facilitating achievement of higher order learning objectives. Eighty‐five students were randomly assigned to three treatment groups: animated program instruction, simple visual‐text (static images and verbal explanation) chunked animated program instruction and the animated complex visual‐text chunked program instruction. The difference between simple and complex chunked instructions is the content. Simple chunks only deal with one content area while the complex chunks explain two or more related content areas. Students interacted with their respective web‐based instructional treatments and completed four criterion measures. Results (ANOVA) indicated that significant differences in achievement were found to exist in facilitating higher order learning objectives when chunking strategies were specifically designed and positioned to complement the animated instruction. Results also indicated that complex chunking is more effective in reducing the cognitive load present in an animated instructional environment, and that students need prerequisite knowledge before being able to profit from animated instruction designed to facilitate higher order learning outcomes.

Direct instruction in math word problems: students with learning disabilities

This investigation was conducted to test the effectiveness of strategy teaching and sequencing practice problems in teaching students with learning disabilities to identify the correct algorithm for solving addition and subtraction word problems. Sixty-two students were assigned to one of three experimental groups: strategy plus sequence, strategy only, and sequence only. The results indicated that students in the strategy-plus-sequence group, as well as those in the strategy-only group, scored significantly higher than did students in the sequence-only group. Findings indicated that strategy teaching was the more effective of the two instructional components. Implications are discussed in terms of instructional design for students with learning disabilities.     

Improving seventh grade students’ learning of ratio and proportion: The role of schema-based instruction

The present study evaluated the effectiveness of an instructional intervention (schema-based instruction, SBI) that was designed to meet the diverse needs of middle school students by addressing the research literatures from both special education and mathematics education. Specifically, SBI emphasizes the role of the mathematical structure of problems and also provides students with a heuristic to aid and self-monitor problem solving. Further, SBI addresses well-articulated problem solving strategies and supports flexible use of the strategies based on the problem situation. One hundred forty eight seventh-grade students and their teachers participated in a 10-day intervention on learning to solve ratio and proportion word problems, with classrooms randomly assigned to SBI or a control condition. Results suggested that students in SBI treatment classes outperformed students in control classes on a problem solving measure, both at posttest and on a delayed posttest administered 4 months later. However, the two groups’ performance was comparable on a state standardized mathematics achievement test.
