Many would agree that learning occurs when new information is stored in memory. Therefore, most learning efforts typically focus on encoding processes, such as additional study or other forms of repetition. However, as I will outline in this thesis, there are other means by which to improve memory, such as retrieval practice in the form of tests. Testing memory has a reinforcing effect on memory, and it improves retention more than an equal amount of repeated study – referred to as the testing effect – and it has been assumed that retrieval processes drive this effect. Recently, however, this assumption has been called into question because of findings that suggest that articulation, that is, the act of providing an explicit response on a memory test, may play a role in determining the magnitude of the testing effect. Therefore, in three studies, I have examined the effects of retrieval and articulation on later retention, in an attempt to ascertain whether the testing effect is entirely driven by retrieval, or if there are additive effects of articulation. I have also explored possible boundary conditions that may determine when, and if, the effects of retrieval and articulation become selective with respect to memory performance. In all three studies, participants studied paired associates and were tested in a cued recall paradigm after a short (~5 min) and a long (1 week) retention interval, and retrieval was either covert (i.e., responses were retrieved but not articulated) or overt (i.e., responses were retrieved and articulated).  In Study I, I demonstrated that uninstructed covert retrieval practice (by means of delayed judgments of learning) produced a testing effect (i.e., improved memory relative to a study-only condition) similar to that of explicit testing, which supports the idea that the testing effect is mainly the result of retrieval processes. In study II, I compared memory performance for covert and overt testing, and found partial support for a relative efficacy in favor of overt retrieval, compared to covert retrieval, although the effect size was small. In Study III, I further explored the distinction between different response formats (i.e., covert retrieval vs. various forms of overt testing), specifically handwriting and keyboard typing. I also examined the relative efficacy of covert versus overt retrieval as a function of list order (i.e., whether covert and overt retrieval is practiced in blocks or random order) and its manipulation within or between subjects. The results of Study III were inconclusive insofar as a relative efficacy of covert versus overt retrieval, with respect to later retention, could not be demonstrated reliably. The list order manipulations did not appear to affect covert and overt retrieval selectively. More importantly, in cases where a relative efficacy was found, the effect size was again small. Taken together, the three studies that of thesis indicate that the benefit of testing memory appears to be almost entirely the result of retrieval processes, and that articulation alone adds very little – if anything – to the magnitude of the testing effect, at least in cued-recall paradigms. These findings are discussed in terms of their theoretical implications, as well as their importance for the development of optimal teaching and learning practices in educational settings. / <p>At the time of the doctoral defense, the following paper was unpublished and had a status as follows: Paper 3: Accepted.</p>

Under de senaste åren har intresset för test baserat lärande ökat och det förekommer evidensatt detta fenomen fungerar inom flera områden som bland annat test format, personligaegenskaper samt återkoppling från ett test. En aspekt som det däremot finns få studier av ärtestbaserat lärande i relation till individuella skillnader i kognition. Den föreliggande studienfokuserar därför på individuella skillnader avseende arbetsminneskapacitet och episodisktminne och dess effekter på ihågkomst av svenska-swahili-ordpar. I studien ingick 163gymnasieelever, varav 82 var flickor och 81 var pojkar med en medelålder om 17.10 år.Multipla regressionsanalyser undersökte deltagarnas förmåga att minnas 60 svenska-swahiliordparfyra veckor efter inlärningsperioden. Analysen visade att både arbetsminneskapacitetoch episodiskt minne predicerar långtidsretention för studerade ordpar. För testbaserat lärandevar det endast det episodiska minnet som signifikant predicerade retentionen. Studien indikeraratt det episodiska minnet, är centralt både för att studera ordpar och att lära in ordpar genomtestbaserat lärande. Däremot är det enbart arbetsminnet som har betydelse för att lära sig ordparvia att studera ordparen. / During the last years, the interest for test-enhanced learning have increased and robust evidenceconcerning test format, personal characteristics and feedback have been obtained. However,few studies have examined test-enhanced learning in relation to cognition. The present studytherefore focused on examine the individual differences in working memory capacity and theepisodic memory and the effects of those on recall of Swedish- Swahili word pairs. The studyincluded 163 students whereof 82 girls were and 81 were boys, with a mean age of 17.10 years.Multiple regressions investigated whether the participated could correctly recall 60 Swedish-Swahili word pairs four weeks after the learning session. The analysis showed that both theepisodic memory and working memory capacity predicted long-term retention for studied wordpairs. For test based learning only the episodic memory had a significant prediction for longterm retention. The study indicate that the episodic memory is central both for learning throughstudy and learning through test-enhanced learning. While working memory was important onlylearning through study.

En ökad efterfrågan på talare av mandarin kinesiska (hädanefterkinesiska) i väst har lett till ett ökat behov av högkvalitetsundervisning i kinesiska. I den här undersökningen studerade 24 svenska modersmålstalare utan tidigare kinesisk språkerfarenhet 60 svenska ord i kombination med deras kinesiska motsvarighet. Hälften av paren lärdes genom upprepade studier (där ordparen presenteras samtidigt) och hälften av paren genom aktiv minneshämtning (där ordparen presenteras separat). Varaktigheten av upprepade studieroch aktiva minneshämtningen likställdes. Alla de kinesiska tecknen presenterades tillsammans med en fonologisk representation. Efter att ha lärtde 60 ordparen, utfördesett flervalstest för att bedöma läranderesultatet. För att testa för den fonologiska representationens betydelse vid inlärning så presenterades hälften av ordparen från varje betingelse utan deras fonologiska representation under testningen. Logistikblandade modellerfann att prestationvar signifikant bättre förupprepade studier jämfört med aktiv minneshämtningoch att tillgång till en fonologisk representation under testninginte gav signifikant bättre testprestanda. / An increased demand for speakers of Mandarin Chinese (henceforth Chinese) in the West has lead to an increased need for high quality teaching of Chinese. In the present study, 24 native Swedish speakers with no prior Chinese language experience studied 60 Swedish words paired with their Chinese equivalents. Half of the pairs were learned by repeated studying (with the word pairs presented simultaneously) and half of the pairs by active retrieval (with the word pairs presented separately). The durations of repeated study and active memory retrieval were equated. All the Chinese characters were presented along with a phonological representation. After learning the 60 word pairs, a multiple-choice test was conducted to assess learning outcome. To test for for the importance of the phonological representation, half of the word pairs learnt in each condition had the representation removed during testing. Logistic mixed models found that performance was significantly better for repeated studying compared to active memory retrieval and that having access to a phonological representation during testing did not yield significantly better test performance.

A primary goal of education is the acquisition of durable knowledge which challenges the use of efficient pedagogical methods of how to best facilitate learning. Research in cognitive psychology has demonstrated that repeated testing during the learning phase improves performance on later retention tests compared to restudy of material. This empirical phenomenon is called the testing effect. The testing effect has shown to be robust across different kinds of material and when compared to different pedagogical methods. Despite the extensive number of published papers on the testing effect, the majority of the studies have been conducted in the laboratory. More specific, few studies have examined the testing effect in authentic settings when using course material during the progress of a course. Further, few studies have investigated the beneficial effects with test-enhanced learning by the use of neuroimaging methods (e.g. fMRI). The aim with the thesis was to investigate the effects of test-enhanced learning in an authentic educational context and how this is related to individual differences in working memory capacity (Study I and II) as well as changes in brain activity involved in successful repeated testing and long term retention (Study III). In study I, we examined whether repeated testing with feedback benefitted learning compared to rereading of introductory psychology key concepts in a sample of undergraduate students. The results revealed that repeated testing with feedback was superior compared to rereading both immediate after practice and at longer delays. The effect of repeated testing was beneficial for students irrespectively of WMC. In Study II, we investigated test-enhanced learning in relation to the encoding variability hypothesis for the learning of mathematics in a sample of fifth-grade children. Learning was examined in relation to both practiced and transfer tasks. No differences were found for the practiced tasks. Regarding the transfer tasks, the results gave support for the encoding variability hypothesis, but only at the immediate test. In contrast, when we followed up the durability of learning across time, the results showed that taking the same questions over and over again during the intervention resulted in better performance across time compared to variable encoding. Individual differences in WMC predicted performance on the transfer tasks, but only at the immediate test, regardless of group. Together, the results from Study I and Study II clearly indicate that testenhanced learning is effective in authentic settings, across age-groups and also produces transfer. Integrate current findings from cognitive science, in terms of test-enhanced learning, by the use of authentic materials and assessments relevant for educational goals can be rather easily done with vi computer based tasks. The observed influence of individual differences in WMC between the studies warrant further study of its specific contribution to be able to optimize the learning procedure. In Study III, we tested the complementary hypothesis regarding the mechanisms behind memory retrieval. Recurrent retrieval may be efficient because it induces representational consistency or, alternatively, because it induces representational variability - the altering or adding of underlying representations as a function of successful repeated retrieval. A cluster in right superior parietal cortex was identified as important for items successfully repeatedly retrieved Day 1, and also correctly remembered Day 7, compared to those successfully repeatedly retrieved Day 1 but forgotten Day 7. Representational similarity analysis in this region gave support for the theoretical explanations that emphasis semantic elaboration.

Resultat från TIMS (Trends in International Mathematics and Science Study, 2019) visar att svenska elever presterar under genomsnittet i matematik både i årskurs fyra och i årskurs åtta. År 2020 sammanfattade Skolinspektionen tre områden som är avgörande för bättre kvalitet i skolan och som sammanfaller väl med bland annat testbaserat lärande. Skolinspektionens (2020) sammanfattning och testbaserat lärandets gemensamma nämnare är vikten av att ha tydliga lärandemål, skapa en varierad och anpassad undervisning som ger elever stimulans och utmaningar efter varje elevs förutsättningar, med stöd av läraren, samt betydelsen av elevers delaktighet och möjlighet till formativa återkoppling.  Mot den bakgrunden samt att det finns grundlig forskning kring testbaserat lärande som högeffektiv inlärningsstrategi analyserades sex lärares erfarenheter av implementeringsarbetet kring testbaserat lärande. Utöver det gjordes en kvantitativ studie inom testbaserat lärande i ämnet matematik. Studien utgår från kognitionsteori och har lärarperspektiv samt en teoretisk referensram i litteratur och artiklar från främst de senaste årtiondena. Efter implementeringen av testbaserat lärande intervjuades sex lärare på en F-6 skola vars undervisning (minst 75 procent av undervisningstillfällena) hade innehållit minst en testbaserad uppgift per lektion under sex veckor. Uppsatsens kvalitativa studie visade lärarnas reaktioner efter implementeringsperioden. De uttryckte en trygghet och motivation i implementeringsarbetet samt hur deras lektionsdesign hade förändrats genom återhämtningsaktiviteterna. De sex lärarna förmedlade också en överraskande positiv upplevelse kring den återkoppling som de testbaserade aktiviteterna gav eleven och läraren, med större möjlighet för läraren att justera sin undervisning för högre måluppfyllelse.Den kvantitativa studien som gjordes i ämnet matematik (aritmetik) i årskurs fyra och fem under en sex-veckors period var en mix av testbaserat lärande (retrieval practice) och delvis inflätat lärande (interleaved practice). Studien med de förutsättningar som gavs visade att testbaserade aktiviteter adderat till delvis inflätat lärande inte höjde resultaten i interventionsgruppen. Vid analysen framkom olika anledningar till resultatet som till exempel utformning och frekvens av de testbaserade aktiviteterna i planeringsschemat, lärarna och elevernas oerfarenhet inom området samt val av interventionsgrupp. / Results from TIMS (Trends in International Mathematics and Science Study, 2019) show that Swedish students perform below average in mathematics for, both in grade four and in grade eight. In 2020, the Skolinsepktionen summarized three areas that are crucial for better quality in schools and that coincide well with, among other things, retrieval practice. Skolverket's (2022) summary and retrieval practice common denominator is the importance of having clear learning goals, creating varied and adapted teaching that gives students stimulation and challenges according to each student's conditions, with the support of the teacher, as well as the importance of student participation and the opportunity for formative feedback. With that background and the fact that there is thorough research on retrieval practice as a highly effective learning method, six teachers' experiences of the implementation work of retrieval practice are analyzed in this essay. In addition to that, a quantitative study is carried out in test-based learning in the subject of mathematics. The study is based on cognitive theory and has a teacher's perspective as well as a theoretical frame of reference in literature and articles from mainly recent decades.  After the implementation of retrieval practice, six teachers were interviewed at an F-6 school whose instruction (at least 75% of the time) had included at least one retrieval practice activity per lesson for six weeks. The essay's qualitative study shows the teachers' positive reactions after the implementation period. They also express a sense of security and motivation in the implementation work and how their lesson design has changed through the recovery activities. The six teachers also convey a surprisingly positive experience regarding the feedback that the retrieval practice activities provide to the student and the teacher, with greater opportunity for the teacher to adjust their teaching for higher goal achievement. The quantitative study that is done in the subject of mathematics (arithmetic) in grades four and five during a six-week period is a mix of retrieval practice and interleaved practice. The study with the conditions provided showed that retrieval practice activities added to interleaved practice did not increase the results in the intervention group. During the analysis, various reasons emerged for the result, such as the design of the retrieval practices activities, frequency of the retrieval practices activities in the planning schedule, the teachers' and students' inexperience in the field, and the choice of intervention group.

A key challenge of the learning sciences is moving research results into practice. Educators on the front lines perceive little value in the outputs of education research and demand more “usable knowledge”. This work explores the potential instead of usable artifacts to translate knowledge into practice, adding scientists as stakeholders in an interaction design process. The contributions are two effective systems, the scientific and contextual principles in their design, and a research model for scientific research through interaction design. College student study practices are the domain chosen for the development of these methods. Iterative ethnographic fieldwork identified two systems that would be likely to advance both learning in practice and knowledge for applying the employed theories in general. Nudge was designed to improve students’ study time management by regularly emailing students with explicit recommended study activities. It reconceptualizes the syllabus into an interactive guide that fits into modern students' attention streams. Examplify was designed to improve how students learn from worked example problems by modularizing them into steps and scaffolding their metacognitive behaviors though problem-solving and self-explanation prompts. It combines these techniques in a way that is exceedingly easy to author, using existing answer keys and students' self-evaluations. Nudge and Examplify were evaluated experimentally over a full semester of a lecture-based introductory chemistry course. Nudge messages increased students’ sense of achievement and interacted with students’ existing time management skills to improve exam grades for poorer students. Among students who could choose whether to receive them, 80% did. Students with access to Examplify had higher exam scores (d=0.26), especially on delayed measures of learning (d=0.40). A key design decision in Examplify was not clearly resolvable by existing theory and so was tested experimentally by comparing two variants, one without prompts to solve the steps. The variant without problem solving was less effective (d=0.77) and less used, while usage rates of the variant with problem solving increased over time. These results support the use of the design methods employed and provide specific empirical recommendations for future designs of these and similar systems for implementing theory in practice.

It is well established that repeated testing is more beneficial for durable learning than repeated studying of the same material, a phenomenon known as the testing effect. This study sought to investigate the role of working memory capacity (WMC) in relation to the learning process and the difficulty of the material to be learned when using a test-enhanced learning method. As between subject manipulation, participants (n = 99, M = 25.62 years of age) were divided into two groups, one using repeated studying and one using alternated testing and studying. A material of two difficulty levels, as well as immediate and delayed retention tests, was used in each condition as within subject manipulation. Further, an n-back task was used to measure WMC. Results from mixed model ANOVAs showed no significant impact of WMC on either the learning process or retention in relation to the difficulty of the material. The testing condition performed significantly higher than the studying condition on the retention tests. The testing effect is further cemented as a promising method for practical application in the educational sector regardless of both WMC and difficulty level. / Det är väl etablerat att upprepad testning är mer fördelaktigt för hållbar inlärning än upprepad instudering av samma material, ett fenomen känt som testeffekten. Denna studie ämnade undersöka arbetsminnets roll i relation till inlärningsprocessen och svårighetsgrad av material med testbaserat lärande som metod. Som mellangruppsmanipulation delades deltagare (n = 99, M = 25.62 år gamla) in i två grupper, en som upprepade gånger studerade materialet och en som alternerade studerande med tester. Ett material med två svårighetsgrader och ett direkt samt fördröjda retentionstester användes som inomgruppsmanipulation. Vidare användes ett n-backtest som mått på arbetsminneskapacitet. Resultat visade ingen signifikant inverkan av arbetsminne på varken inlärningsprocessen eller retention i relation till svårighetsgrad av material. Testbetingelsen presterade signifikant högre på retentionstest än studiebetingelsen. Testeffekten fastställs ytterligare som lovande metodik för praktisk applikation i utbildningssektorn oberoende av både arbetsminneskapacitet och svårighetsgrad.

Many older adults desire to maintain their quality of life by living and aging independently in their own homes. However, it is difficult for older adults to notice and track the subtle changes in their own abilities because these abilities can change gradually over a long period of time. Technology in the form of ubiquitous sensors embedded in objects in the home can play a role in keeping track of the functional abilities of individuals unobtrusively, objectively, and continuously over a long period of time. This work introduces a sensing technique called “task-based embedded assessment” that monitors how well specific tasks important for independence are carried out using everyday objects found in the home with which individuals regularly interact. Following formative studies on the information needs of older adults and their caregivers, a sensing system called “dwellSense” that can monitor, assess, and provide feedback about how well individuals complete tasks, such as taking medications, using the phone, and making coffee, was designed, built, and evaluated. Multiple longterm (over 10 months) field deployments of dwellSense were used to investigate how the data collected from the system could support greater self-awareness of abilities and intentions to improve in task performance. Presenting and reflecting on data from ubiquitous sensing systems such as dwellSense is challenging because it is both highly dimensional as well as large in volume, particularly if it is collected over a long period of time. Thus, this work also investigates the time dimension of reflection and has identified that real-time feedback is particularly useful for supporting behavior change, and longer-term trended feedback is useful for greater awareness of abilities. Traditional forms of assessing the functional abilities of individuals tend to be either biased, lacking ecological validity, infrequent, or expensive to conduct. An automated sensor-based approach for assessment is compared to traditional performance testing by a trained clinician and found to match well with clinician-generated ratings that are objective, frequent, and ecologically valid. The contributions from this thesis not only advance the state of the art for maintaining quality of life and care for older adults, but also provide the foundations for designing personal sensing systems that aim to assess an individual’s abilities and support behaviors through the feedback of objective, timely sensed information.
