Evidence for distinct serial processes in animals: The multiplicative-factors method

The assumption that responses are controlled by distinct serially arranged processes was used by Sternberg (1969a) to explain the result, observed in many human experiments, that two factors have additive effects on reaction time (RT). With slight changes, Sternberg’s explanation of additive factors with RT also explains the result, observed in animal experiments, that two factors have multiplicative effects on response rate. This article describes and interprets 17 examples of multiplicative factors from response-rate experiments with rats, pigeons, and goldfish, as well as some other animal evidence for distinct serial processes. The examples suggest and/or support new and old ideas about generalization, attention, timing, learning, motivation, and response production. Most important, the animal evidence makes the case for distinct serial processes considerably stronger. Since the procedures used in the two sets of experiments (human and animal) have little in common, distinct serial processes may control behavior in a very wide range of situations.

Students' response to traditional and computer-assisted formative feedback: A comparative case study

The national movement towards progress files, incorporating personal development planning and reflective learning, is supported by lecturers providing effective feedback to their students. Recent technological advances mean that higher education tutors are no longer obliged to return comments in the ‘traditional’ manner, by annotating students' work with red pen. This paper considers some of the options currently available for returning computer‐assisted feedback, including the Electronic Feedback freeware. This MS Office application enables tutors to readily synthesise and email feedback reports to students. To further ascertain the value of this software, 169 1st‐year Pharmaceutical Science and Pharmacy students completed a questionnaire to gauge their reaction to formative feedback on an extended laboratory report. This included 110 responses from students graded by three tutors who marked work using either handwritten annotations or the Electronic Feedback program. Principle component analysis (PCA) of the Likert scale responses indicates that the identity of the marker did not significantly affect the response of students. However, the type of feedback was a factor that influenced the students' responses, with electronic feedback being rated superior. A Mann‐Whitney analysis of the satisfaction ratings (generated by PCA) indicates that four features of the assignment and feedback were considered significantly improved when the software was used to create feedback, namely; markscheme clarity, feedback legibility, information on deficient aspects, and identification of those parts of the work where the student did well. Modern academics face a number of challenges if they wish to return meaningful and timely feedback to students, among them large class sizes and infrequent face‐to‐face contact. It is pleasing to note, therefore, that assessors reported taking less time to mark when using the software. It is concluded that electronic formative feedback can be returned more quickly and may be used to synthesise relevant feedback that is both fair and balanced.     

Agency and conformity in school-based teacher training

Concern has been expressed that the current climate in schools militates against trainee teachers’ self-directed development. This article explores the issue of trainees’ capacity for self-direction through the analysis of interviews with 32 trainees, investigating their perceived proactive social strategies. Three proactive strategies were identified: ‘tactical compliance’, personalising advice, and seeking out opportunities to exercise control. It is argued that these strategies are indicative of trainees’ drive to establish a personal teaching identity through self-directed development and the creation of individual development agendas. The article concludes by emphasising the importance of the development of proactive social skills in beginning teachers.     

Keep DRAGging ON: Is solving more problems in DragonBox 12+ associated with higher mathematical performance during the COVID-19 pandemic?

Prior research has shown that game-based learning tools, such as DragonBox 12+, support algebraic understanding and that students' in-game progress positively predicts their later performance. Using data from 253 seventh-graders (12–13 years old) who played DragonBox as a part of technology intervention, we examined (a) the relations between students' progress within DragonBox and their algebraic knowledge and general mathematics achievement, (b) the moderating effects of students' prior performance on these relations and (c) the potential factors associated with students' in-game progress. Among students with higher prior algebraic knowledge, higher in-game progress was related to higher algebraic knowledge after the intervention. Higher in-game progress was also associated with higher end-of-year mathematics achievement, and this association was stronger among students with lower prior mathematics achievement. Students' demographic characteristics, prior knowledge and prior achievement did not significantly predict in-game progress beyond the number of intervention sessions students completed. These findings advance research on how, for whom and in what contexts game-based interventions, such as DragonBox, support mathematical learning and have implications for practice using game-based technologies to supplement instruction.

Practitioner notes

What is already known about this topic

• DragonBox 12+ may support students' understanding of algebra but the findings are mixed.
• Students who solve more problems within math games tend to show higher performance after gameplay.
• Students' engagement with mathematics is often related to their prior math performance.

What this paper adds

• For students with higher prior algebraic knowledge, solving more problems in DragonBox 12+ is related to higher algebraic performance after gameplay.
• Students who make more in-game progress also have higher mathematics achievement, especially for students with lower prior achievement.
• Students who spend more time playing DragonBox 12+ make more in-game progress; their demographic, prior knowledge and prior achievement are not related to in-game progress.

Implications for practice and/or policy

• DragonBox 12+ can be beneficial as a supplement to algebra instruction for students with some understanding of algebra.
• DragonBox 12+ can engage students with mathematics across achievement levels.
• Dedicating time and encouraging students to play DragonBox 12+ may help them make more in-game progress, and in turn, support math learning.

     

Effects of implementation support on children's reading outcomes following an online early reading programme: A cluster-randomised controlled trial

Well-designed computer or app-based instruction has a number of potential benefits (eg increasing accessibility and feasibility of high-quality instruction, reducing time and resources required for training expert delivery, saving instructional time). However, variation in implementation can still affect outcomes when using educational technology. Research generally suggests that without follow-up support after training, implementation of educational interventions is often poor and outcomes reduced. However, the extent to which this is the case when the core element of an intervention is computer or app-delivered is not yet clear. This study investigated the effects of providing ongoing implementation support for Headsprout Early Reading (HER, an early reading programme accessible via a computer or an app), to determine whether such support leads to better outcomes. Twenty-two primary schools (269 learners) participated in a cluster-randomised controlled trial. Eleven schools received initial training followed by ongoing support across the school year, whereas the other 11 schools received initial training and technical support only. Pre- and post-measures of reading skills were conducted using the York Assessment of Reading for Comprehension. We found no effect of implementation support on outcomes, and no effect of implementation support on delivery of the core element of HER. However, there were some effects of implementation support on the implementation of other HER elements relating to the responsiveness of educators to learners' learning within HER. These findings have implications for providing access to high quality online instruction in early reading skills at scale, with minimal training. More broadly, the current study suggests that well-designed computer or app-based instruction can yield positive outcomes with minimal implementation support and training. However, further research is required to ensure the interplay between learners' app-based learning and teacher intervention functions as intended to provide additional support for those who need it.

What this paper adds

• We found that providing implementation support for teachers and teaching assistants delivering Headsprout Early Reading (HER; an early reading programme accessible via a computer or an app) did not affect the reading outcomes of learners.
• We also found the implementation support did not affect delivery of the core, app-delivered element of the programme.
• However, there were notable differences in implementation of other aspects of the programme, particularly in relation to the role of the teacher or educational practitioner in managing the interplay between the app-based learning and teacher intervention for learners who require further support.

Implications for practice and policy

• These findings have implications for providing access to high quality instruction in early reading skills at scale, with minimal training.
• More broadly, the current study suggests that well-designed computer or app-based instruction can yield positive outcomes with minimal implementation support and training.
• However, the findings of this study identify some potential risk of an over-reliance on technology to facilitate the learning of all learners accessing the programme.
• Further research is required to ensure the interplay between learners' app-based learning and teacher intervention functions as intended to provide additional support for those who need it.
