Content and timing of feedback in a web-based learning environment: effects on learning as a function of prior knowledge

This study investigated the effectiveness of different types of feedback content (elaborate versus global) and feedback timing (immediate versus delayed) for learning genetics in a web-based learning environment as a function of learners' prior knowledge. It was hypothesized that learning outcomes of students with low prior knowledge would be fostered by immediate elaborate feedback, whereas those of students with more prior knowledge would be enhanced by delayed global feedback. Students' perceptions of the feedback they received were explored. Results showed a significant positive effect of global feedback on learning outcomes for higher prior knowledge learners, although those who received elaborate feedback gave a higher appreciation rating. The findings are discussed in terms of implications for the design and delivery of feedback in web-based learning environments.     

Professional knowledge affects action-related skills: The development of preservice physics teachers' explaining skills during a field experience

Professional knowledge is an important source of science teachers' actions in the classroom (e.g., personal professional content knowledge [pedagogical content knowledge, PCK] is the source of enacted PCK in the refined consensus model [RCM] for PCK). However, the evidence for this claim is ambiguous at best. This study applied a cross-lagged panel design to examine the relationship between professional knowledge and actions in one particular instructional situation: explaining physics. Pre- and post a field experience (one semester), 47 preservice physics teachers from four different universities were tested for their content knowledge (CK), PCK, pedagogical knowledge (PK), and action-related skills in explaining physics. The study showed that joint professional knowledge (the weighted sum of CK, PCK, and PK scores) at the beginning of the field experience impacted the development of explaining skills during the field experience (β = .38**). We interpret this as a particular relationship between professional knowledge and science teachers' action-related skills (enacted PCK): professional knowledge is necessary for the development of explaining skills. That is evidence that personal PCK affects enacted PCK. In addition, field experiences are often supposed to bridge the theory-practice gap by transforming professional knowledge into instructional practice. Our results suggest that for field experiences to be effective, preservice teachers should start with profound professional knowledge.     

The differential effects of prior knowledge on learning: A study of two consecutive courses in earth sciences

We studied the occurrence and nature of learningin a university first year Introduction toGeomorphology course, and its relations with priorknowledge taught in a prerequisite course, and withthe prior knowledge in the to be learned subjects. Tendimensions of knowledge were tapped before and afterthe course by conventional and cognitive structuremeasures that were derived by the concept mappingmethodology. The fine-grain analysis of learningoutcomes yielded the following results: (a) studentsacquired only a small portion of the content in thecourse Introduction to Geomorphology, (b) the priorgeological and geomorphological knowledge did notaffect the learning of the new geomorphologicalcontents, (c) the minor effects appeared within ratherthan across knowledge dimensions, and they affectedmainly the learning of smaller knowledge units, and(d) concept definition cannot be considereda valid probe of knowledge. The differential effects of prior knowledge question thecentral, global and undifferentiated role that schematheories ascribe to prior knowledge in futurelearning. They call for greater reference to theexposed dimensions of knowledge by suggestingadditional factors to be considered in the sequencingof courses, as well as to the acquisition of complexknowledge with partial meaning of the basic knowledgeunits, and the use of new cognitive structure probesof knowledge.     

The influence of prior knowledge on experiment design guidance in a science inquiry context

Designing and conducting sound and informative experiments is an important aspect of inquiry learning. Students, however, often design experiments that do not allow them to reach conclusions. Considering the difficulties students experience with the process of designing experiments, additional guidance in the form of an Experiment Design Tool (EDT) was developed, together with reflection questions. In this study, 147 pre-university students worked in an online inquiry learning environment on buoyancy and Archimedes’ principle. Students were randomly assigned to one of three conditions, each of which contained a different version of the EDT. Since students’ prior knowledge has been found to influence the amount and type of guidance they need, the versions of the tool differed with respect to the level of guidance provided. A pre- and post-test were administered to assess students’ conceptual knowledge. No overall differences between conditions were found. In a subsequent analysis, students were classified as either low, low-intermediate-, high-intermediate, or high prior knowledge students. For Archimedes’ principle we found that low-intermediate prior knowledge students gained significantly more conceptual knowledge than low prior knowledge students in the fully guided condition. It is hypothesised that students need at least some prior knowledge in order to fully benefit from the guidance offered.     

The mediating effects of needs satisfaction on the relationships between prior knowledge and self-regulated learning through artificial intelligence chatbot

The anthropomorphic characteristics of artificial intelligence (AI) can provide a positive environment for self-regulated learning (SRL). The factors affecting adolescents' SRL through AI technologies remain unclear. Limited AI and disciplinary knowledge may affect the students' motivations, as explained by self-determination theory (SDT). In this study, we examine the mediating effects of needs satisfaction in SDT on the relationship between students' previous technical (AI) and disciplinary (English) knowledge and SRL, using an AI conversational chatbot. Data were collected from 323 9th Grade students through a questionnaire and a test. The students completed an AI basic unit and then learned English with a conversational chatbot for 5 days. Confidence intervals were calculated to investigate the mediating effects. We found that students' previous knowledge of English but not their AI knowledge directly affected their SRL with the chatbot, and that satisfying the need for autonomy and competence mediated the relationships between both knowledge (AI and English) and SRL, but relatedness did not. The self-directed nature of SRL requires heavy cognitive learning and satisfying the need for autonomy and competence may more effectively engage young children in this type of learning. The findings also revealed that current chatbot technologies may not benefit students with relatively lower levels of English proficiency. We suggest that teachers can use conversational chatbots for knowledge consolidation purposes, but not in SRL explorations.

Practitioner notes

What is already known about this topic

• Artificial intelligence (AI) technologies can potentially support students' self-regulated learning (SRL) of disciplinary knowledge through chatbots.
• Needs satisfaction in Self-determination theory (SDT) can explain the directive process required for SRL.
• Technical and disciplinary knowledge would affect SRL with technologies.

What this paper adds

• This study examines the mediating effects of needs satisfaction in SDT on the relationship between students' previous AI (technical) and English (disciplinary) knowledge and SRL, using an AI conversational chatbot.
• Students' previous knowledge of English but not their AI knowledge directly affected their SRL with the chatbot.
• Autonomy and competence were mediators, but relatedness was not.

Implications for practice and/or policy

• Teachers should use chatbots for knowledge consolidation rather than exploration.
• Teachers should support students' competence and autonomy, as these were found to be the factors that directly predicted SRL.
• School leaders and teacher educators should include the mediating effects of needs satisfaction in professional development programmes for digital education.

Exploring how children with reading difficulties respond to instructional supports in literacy games and the role of prior knowledge

Digital literacy games can be beneficial for children with reading difficulties as a supplement to classroom instruction and an important feature of these games are the instructional supports, such as feedback. To be effective, feedback needs to build on prior instruction and match a learner's level of prior knowledge. However, there is limited research around the relationship between prior knowledge, instruction and feedback in the context of learning games. This paper presents an empirical study exploring the influence of prior knowledge on response to feedback, in two conditions: with or without instruction. Thirty-six primary children (age 8–11) with reading difficulties participated: each child was assessed for their prior knowledge of two suffix types—noun and adjective suffixes. They subsequently received additional instruction for one suffix type and then played two rounds of a literacy game—one round for each suffix type. Our analysis shows that prior knowledge predicted initial success rates and performance after a verbal hint differently, depending on whether instruction was provided. These results are discussed with regards to learning game feedback design and the impact on different types of knowledge involved in gameplay, as well as other game design elements that might support knowledge building during gameplay.

Practitioner notes

What is already known about this topic

• Instructional supports, such as elaborative feedback, are a key feature of learning games.
• To be effective, feedback needs to build on prior instruction and match a learner's level of prior knowledge.
• Prior knowledge is an important moderator to consider in the context of elaborative feedback.

What this paper adds

• Providing additional instruction (eg, pre-training) may act as a knowledge enhancer building on children's existing disciplinary expertise, whereas the inclusion of elaborative feedback (eg, a hint) could be seen as a knowledge equaliser enabling children regardless of their prior knowledge to use the pre-training within their gameplay.
• Highlights the importance of children's preferred learning strategies within the design of pre-training and feedback to ensure children are able to use the instructional support provided within the game.
• Possible implications for pre-training and feedback design within literacy games, as well as highlighting areas for further research.

Implications for practice and/or policy

• Pre-training for literacy games should highlight key features of the learning content and explicitly make connections with the target learning objective as well as elaborative feedback.
• Pre-training should be combined with different types of in-game feedback for different types of learners (eg, level of prior knowledge) or depending on the type of knowledge that designers want to build (eg, metalinguistic vs. epilinguistic).
• Modality, content and timing of the feedback should be considered carefully to match the specific needs of the intended target audience and the interaction between them given the primary goal of the game.

     

The effect of financial education on pupils’ financial knowledge and skills: Evidence from a Solomon four-group design

Abstract

The present study used a Solomon four-group quasi-experimental design to examine the short-term effect of a large-scale national financial education program on children’s knowledge and skills in responsible spending and performing transactions effectively. Our study included a representative sample of Dutch pupils in the fifth grade of primary school (N?=?2,650). Controlling for different children-specific characteristics, results showed that the program increased pupils’ knowledge and skills scores in performing transactions effectively, but not in responsible spending. The insights gained from the present study show how financial education programs that enable children to immediately apply what they learn in practice can improve children’s knowledge and skills regarding certain financial competencies.     

Epistemic beliefs and prior knowledge as predictors of the construction of different types of arguments on socioscientific issues

This study investigates whether university students’ epistemic beliefs and prior knowledge about controversial socioscientific issues (SSIs) can predict the different types of arguments that students construct. Two hundred forty-three university students were asked to construct different types of supportive arguments—social, ethical, economic, scientific, ecological—as well as counterarguments and rebuttals after they had read a scenario on a SSI. Participants’ epistemic beliefs and prior knowledge were assessed separately. Results showed that students’ epistemic beliefs and prior knowledge predicted the quantity, quality, and diversity of the different types of arguments the students constructed. In particular, students who held sophisticated epistemic beliefs about the structure of knowledge and exhibited relatively more robust prior knowledge scores, produced arguments of greater quantity, better quality, and higher diversity than students with less sophisticated epistemic beliefs and low prior knowledge scores. Educational implications are discussed.

The impact of diversity,prior academic achievement and goal orientation on learning performance in group capstone projects

ABSTRACT

Capstone projects are common in undergraduate programmes, providing students with a culminating educational experience designed to draw on the knowledge and skills accumulated over the course of their studies. While there are many benefits to capstone projects, they are not without challenges. In particular, when these projects are conducted in groups, forming groups to optimise the learning outcomes and managing group dynamics can be challenging. In this article, we report on the analysis of data collected from 346 undergraduate business students who completed capstone projects at a Hong Kong university. Measures included students’ learning goal (mastery and performance), satisfaction with their supervisor and group diversity in relation to gender, prior academic achievement, self-report nationality and programme of study. Analysis of this data in conjunction with student grades for the project was conducted to inform improvements in design and delivery of the capstone subject to improve students’ learning outcomes. The results showed that for groups consisting of three students, group diversity in respect to prior academic achievement as measured by grade point average (GPA) is positively related to the grade achieved in the capstone project. However, diversity in respect to the nationalities in the group was related to poorer performance. Furthermore, the more teacher-focused the group supervisor’s approach was, the worse the grade achieved for the project. The results suggest that groups made up of students of different nationalities tend to have lower grades compared to homogeneous groups. In contrast, having a group with a mix of GPAs can result in higher grades on the project. While these findings have informed our understanding of group performance on capstone projects, work is needed to fully understand what underlies the diversity effects identified which will be explored with future cohorts.     

The role of letter knowledge acquisition ability on children's decoding and word identification: Evidence from an artificial orthography

Background

Letter knowledge is crucial in the first stages of reading development. It supports learning letter-sound mappings and the identification of the letters that make up words. Previous studies have investigated the longitudinal impact of early letter knowledge on children's further word reading abilities. This study employed an artificial orthography learning paradigm to explore whether the rate of letter learning modulates children's reading and word identification skills.

Methods

In an initial training phase, 8-year-old Spanish children (N = 30) learned nine artificial letters and their corresponding sounds (two vowels and six consonants). The letter learning rate was set according to the number of attempts needed to name at least seven letters (i.e., 80% correct). These ranged from 1 to 4. In a second training phase, children visualized words made up of the trained letters while listening to their pronunciations. Some words included a context-dependent syllable (i.e., leading to grapheme-to-phoneme inconsistency), and others had an inconsistent syllable (i.e., phoneme-to-grapheme inconsistency). The post-test consisted of a reading aloud task and an orthographic-choice task in which the target word was presented with a distractor equal to the target except for the substitution of a letter.

Results

Children showed a high accuracy rate in the post-test tasks, regardless of whether words contained context-dependent or inconsistent syllables. Critically, the letter learning rate predicted both reading aloud and identification accuracy of words in the artificial orthography.

Conclusions

We provide evidence for the vital role of letter knowledge acquisition ability in children's decoding and word identification skills. Training children on this ability facilitates serial letter-sound mapping and word identification skills. Artificial orthography paradigms are optimal for exploring children's potential to achieve specific literacy skills.

     

Towards an environmental education without scientific knowledge: an attempt to create an action model based on children's experiences,emotions and perceptions about their environment

The paper presents an alternative approach to environmental education which focuses on children's ideas and action rather than scientific knowledge. The approach is based on children's willingness and ability to act and participate in their community and environment. The paper contributes to the development of an alternative pedagogical proposition for environmental education that is inspired by critical education. The proposed action model has emerged from a one‐year qualitative, participatory research in a pilot primary school in Athens, with the active engagement of 60 children, aged 9–12. The action model describes a path from denial of action to willingness for action. It can be used to encourage children to become involved in their environment and community and to feel strong and confident to act.     

Developing observational skills and knowledge of anatomical relationships in an art and anatomy workshop using plastinated specimens

One of the strong trends in medical education today is the integration of the humanities into the basic medical curriculum. The anatomy program is an obvious choice for using the humanities to develop professionalism and ethical values. They can also be used to develop close observational skills. Many medical schools have developed formal art observation training in conjunction with nearby art museums to enhance the visual diagnostic skills of their medical students. We report here on an art and anatomy workshop that paired medical and art students who did drawing exercises from plastinated anatomical specimens and the animated face to hone observational skills. Each member of the pair brought a different perspective and expertise to the work that allowed each to be a mentor to the other. The workshop had three sessions: the first involved drawings of plastinated specimens that allowed an intimate experience with authentic human material; the second involved drawings of the human face; and the third included examination of anatomical texts of important anatomist-artists, a lecture on contemporary artists whose work involves anatomy, and a film demonstrating the facial muscles. We propose workshops such as these will help students increase their ability to detect details. This will assist the medical student in developing diagnostic skills for identifying disease and the art student in using the human body as subject. We further propose that these programs will help students develop humanistic sensitivities and provide an outlet for expression of the emotional aspects of dealing with disease and mortality.     

Investigating effects of the quality of field experiences and personality on perceived teaching skills in German pre-service teachers for secondary schools

Quality of field experiences during teacher education as well as individual characteristics of student teachers are considered important for the development of teaching skills. In the present study we investigated both organizational and individual predictors of self-rated teaching skills in student teachers for secondary schools in Germany (N = 443). As predictor variables for teaching skills after a field experience we assessed the perceived quality of the internship as well as personality traits, as control variables prior educational experiences and academic abilities. The assessed quality feature “linking theory and practice” explained more variance in the prediction of teaching skills than personality traits.     

The influence of feedback of diagnosis and executive function skills on rates of false positive and false negative outcomes for ADHD

This study examined executive function (EF) skills and self-reported symptoms of ADHD. EF skills were measured to determine whether skills were different between groups that reported clinical levels of ADHD symptoms (clinical group) and nonclinical levels of ADHD symptoms (nonclinical group). EF skills in the nonclinical group were also investigated to determine whether differences existed for those who received false positive and negative feedback about an ADHD diagnosis. Results indicated statistically and clinically significant differences in EF skills between the clinical and nonclinical group. Participants in the nonclinical group who reported elevated scores on the ADHD screener after receiving false positive feedback had statistically significantly different EF function scores, but not clinically significant scores, compared to the participants in nonclinical group who received negative feedback.
