This document discusses using proactive anonymous feedback to enhance student learning in engineering courses. It presents a feedback process where students anonymously provide feedback on topics after each class using an online form. The instructor then adapts teaching based on this feedback. Results showed students earned higher grades and gave the instructor better evaluations when this approach was used compared to traditional methods. Student feedback indicated concepts were clearer due to things like animations and examples. This suggests proactive anonymous feedback can help improve student learning and teaching effectiveness.

Enhancing Student Learning through Proactive Feedback Based Adaptive Teaching...IJITE
This paper presents a proactive anonymous feedback based adaptive teaching for enhancing student
learning for engineering courses. In conventional university teaching, typically, students come to the class
and instructors lecture the material, assign home assignments, take exams, etc. After grading assignments
or exams, the instructor provides feedback to students. Most of the time, students are reluctant to ask
questions or ask instructor to revisit the topic which was already covered. However, there is no immediate
anonymous feedback mechanism for each topic or class to notify the instructor about topics which are not
clear to students. There are advantages that enhance students’ learning experience by using a proactive
anonymous feedback approach in teaching, learning and assessment. In this paper, we present the
immediate impacts of proactive anonymous feedback based adaptive teaching on student learning and
assessment. Furthermore, anonymous online based feedback mechanism provides faster feedback than
conventional mechanism (where students wait until the first exam or so). Immediate feedback for each topic
discussed in the class streamlines the process of reporting and the provision of active studying. The results
show that students get better grade and instructors get better student evaluation score since the anonymous
feedback provides a mechanism for students to ask questions anonymously and the instructors get an
opportunity to answer the questions or concerns in a timely manner. We implemented the proactive
anonymous feedback approach in many courses in different semesters and observed similar results.
However, as an example, we present one course and instructor to illustrate the effectiveness of the
proposed approach.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

1.INTRODUCTION
Most university students learn through attending lectures, completing homework assignments and
quizzes, participating in face-to-face group tutorials, and attending in exams as part of full-time
campus-based programs [1,3,4,5]. Students get opportunities to interact with their professors or
instructors in the classroom as well as during allocated office hours. However, most of the
students are reluctant to ask in the class as they might feel that the questions they ask are very
basic or advanced [1,2,4]. The only way to ask questions either by sending email or meeting
professors during office hours. Even in this case, most students are reluctant to ask questions as
they have fear of being identified as a weak student. Only option available to students is study by
themselves or ask colleagues. In this paper, we present a proactive anonymous feedback
mechanism where students use online forms (e.g., Google form) to provide anonymous feedback
to their instructors and ask questions about any topics that is not clear to them. This feedback
mechanism doesn’t collect any private information that identifies the students. Thus, student can

ask any questions fearlessly. Note that the proposed proactive anonymous feedback mechanism is
in addition to regular homework assignment, quizzes, tests, class discussions, term paper
assignment, etc. There are many advantages that enhance students’ learning experience by using a
proactive anonymous feedback approach in teaching, learning and assessment. Furthermore,
anonymous online based feedback mechanism provides faster feedback than conventional
mechanism (where students wait until the first exam or so). Immediate feedback for each topic
discussed in the class streamlines the process of reporting and the provision of active studying for
feedback. The results show that students get better grade and instructors get better student
evaluation score since the feedback provides a mechanism for student to ask questions
anonymously and instructors get a chance to answer the questions or concerns in a timely manner.
We implemented the proactive anonymous feedback approach in many courses in different
semesters and observed similar results. In this paper, as an example, we present one course and
instructor to illustrate the effectiveness of the proposed proactive anonymous feedback approach.
Most recent related works include [6,7,8] where students receive feedback from instructors
through corrected assignments (homework, testes, quizzes, exams, etc.). Using these assignments
as references, instructor realizes that the students are not at the level that instructed expected.
Furthermore, students who are not hesitant to speak out in the class can also provide some
feedback so that instructor can identify the problems and adapt his/her teaching style or material
to improve teaching and learning for the betterment of the students. It is worth noting that using
these approaches, instructors do not receive feedback about their teaching style and materials in a
timely manner. Furthermore, these approaches are not proactive and are not capable of providing
mechanism of giving anonymous feedback to the instructor from which most students get benefit.
2.METHODOLOGY/PROCESS
In each class, instructors presented the agenda where announcements are announced first and
followed by the review as shown in Figure 1. The review of previous topics is done to connect the
previous topics with the topics that are going to be discussed in the class. During this review time,
instructor also reviews the topics mention in the anonymous feedback. The instructor also
proactively asks the students about anonymous feedback for the topic or any questions that
students have (if any). Students are also suggested to study the lecture material (for at least 15
minutes) after each class. This helps students to understand the topics discussed in the class. If
something is still not clear yet, students are encourages to write about what is unclear to them and
the instructor should consider revisiting in the following class before starting the next topic.

2.1.Feedback Forms and Process
This section presents feedback form and process that are used in anonymous feedback process for
engineering courses. Figure 2 shown the form for EENG 5532 Wireless Communications course
as an example. The process of collecting feedback is anonymous to give students an opportunity
to share their thoughts and feelings about the given topic, lecture materials, instructors, etc.
without releasing their identity or without any fear.
A typical list of topics covered in wireless communications course at GSU are listed as shown in
Figure 2. After finishing each topic, students are encourages to provide feedback about the topic,
instruction methods, etc. by choosing the correct item from dropdown box as shown in Figure 2.
Figure 2. List of topics for the given course listed in dropdown list.
Figure 3 shows the complete list of questions (with additional overall feedback) about the topic
covered in wireless communications course. When instructor covered a given topic in the class,
students are asked/encourages to participate in this anonymous feedback process within 24 hours.
This early feedback allows instructor to read the comments/feedback in a timely manner.
Furthermore, if there are some topics unclear to students, instructor gets an opportunity to revisit
the topics based on the feedback while reviewing the previous topics in the class. The main goal
of this process is to help students to relate the topics and make connection between different
topics that were covered in different classes.
Regardless of the feedback from students, instructors revisit the previous topics to make smooth
transitions between two topics (topics discussed in the previous class and topics that are going to
be discussed). Note that, on top of feedback, instructor assigns home assignment every week, at
least a quiz after finishing each topic, term paper for the course, at least three test (including final
exam) for the evaluation and assessment.

2.2.Feedback Response for a Given Course
As mentioned, after covering each topic students were encouraged to participate in the feedback
process. The feedback provided by the students was read by the instructor and took adaptive
action to close the loop and for better teaching and learning process. In addition to homework and
tests, pop-up quizzes were also assigned during class time to assess the effectiveness of teaching
and learning. Students were provided their progress in a regular basis.
The Table 1 below shows the number of responses received in spring 2014 and spring 2016 for
each topic of the given course. Most of the students were participating with some exception. For
example, there were very few providing for the last topic as the topic was discussed in the very
last class and student might have thought that there is no time for the instructor to provide the
response to students.

2.4.Student Rating Collected Through the Feedback Process
Figure 4 shows the average score for feedback questions for each topic of the course. Except very
few, most of the topics were interesting to all students as average score is 5 out of 5. The lower
rating may be because of the students who missed previous class and felt disconnected in the
following class as a result they gave low ratings.

given course based on Figure 3.
2.5.Impact on Learning Outcomes, Grades and Assessment
Figure 5. Students’ average score in different assessment and evaluation methods in two different
semesters.

We then plotted the average grades for different evaluation methods for the given course for
spring 2014 and spring 2015. We observed that students got lower average grades in spring 2014
than that in spring 2015. This happened as the instructor implemented the feedback approach
more effectively and emphasized the importance of studying the lecture material after each class
at least for 15 minutes. We also observed that there was no significant difference in average score
for term paper as there was no direct impact of feedback process.
2.6.Students Evaluation Conducted by the Department
All data presented in this section are based on the student evaluation conducted independently for
each course in a given semester by the Department of Electrical Engineering at GSU on behalf of
the instructor. These scores were provided to the instructor by the department in the following
semester (e.g. fall 2014 student evaluation reports were reported to the instructor in spring 2015)
in order not to have any effect on student grading.
We then plotted the student evaluation score for the instructor for different courses as shown in
Figure 6. We observed that the instructor’s ratings are 4.5 or higher (out of 5) except fall 2013. It
is important to point out that high rating is not only because of feedback approach but also
because of the instructor’s teaching skills and philosophy, integration of other technologies in the
class, making learning process fun and enjoyable.
Figure 6. Student response to “Overall, how would you rate this instructor?” out of 5 for
difference courses.
Next, we plotted the score for the Students’ Interest Level before and after taking the course as
shown in Figure 7. We observed that student interest level significantly improved after taking the
course in all courses, as expected. This is because of the instructor’s extra effort to make sure that
students understood the fundamental concept through analogy, example, demonstrations,
animations, PowerPoints, challenging homework assignment, quizzes, exams, etc.

Finally, we plotted the average score for student evaluation for a given course and content
(out of 5 band score) for different courses and semesters as shown in Figure 8. The average score
for each item (shown in legend of Figure 8) is higher than 4.5 (out of 5) accept that for fall 2013
EENG 5540.
Figure 8 Student evaluation for a given course and content (out of 5 band score) for different courses and
semesters.
We conclude this section by noting down that we observed similar results for other instructors
who followed the similar style and the proposed approach. Thus we omitted those results in this
paper.

3.CONCLUSION
In this paper, we have presented a proactive anonymous feedback based adaptive teaching for
enhancing student learning for engineering courses. In conventional university teaching, there are
no immediate anonymous feedback mechanisms for each topic to notify the instructor about
topics which are not clear to students. There are advantages that enhance students’ learning
experience by using a proactive anonymous feedback approach in teaching, learning and
assessment. Furthermore, anonymous online based feedback mechanism provides faster feedback
than conventional mechanism (where students wait until the first exam or so). Immediate
feedback for each topic discussed in the class streamlines the process of reporting and the
provision of active studying habit for students. The study shows that students get better grade and
the instructors get better student evaluation score since the anonymous feedback provides a
mechanism for students to ask questions anonymously and the instructors get an opportunity to
answer the questions or concerns in a timely manner.
ACKNOWLEDGEMENTS
The authors would like to thank the students who participated in the feedback process for
different courses and process of collecting data. Authors would also like to thank the anonymous
reviewers who provided valuable feedback to improve the quality of the paper.
